Here is a summary: "This sketch presents a system that generates procedural textures or shaders using genetic algorithm techniques. The system operates in both artist directed and automatic texture matching modes." P.S. All shaders are generated using Genetic Shaders and all images are rendered using RenderMan. I hope to see you there, please pass this invitation to your friends and colleagues.

I agree, and I've mentioned so before. I think everyone would admit that OD is a better tool for the end user. But that doesn't mean that you should knock IB for what it really does: connect live objects together. (You do remember that this really started as VB vs. IB, then wanged off as you dropped some OD stuff in, knocking it for stuff it *can* do.). While IB is base framework for connecting live objects, OD is a framework which includes dymanic view sharing and data exchange. It's an artifact of it's history that IB is intended as a programmer tool and doesn't need to define the interface for data exchange, etc. That doesn't meam it doesn't facilitate such things, look at Enterprise Objects. IB is a foundation, OD is something a bit higher. >Rather than saying "oh, gee, IB/NeXT can already do much/most of what >OpenDOc does, but in a different way," why not acknowledge that OD has a >great deal to offer Rhapsody as far as parts-nesting/interaction/GUI issues >go, and work on designing a hybrid that combines the *complete* >functionality of OD and the *complete* functionality of the AppKit and >whatever IB has to offer that is appropriate for generic components? An important point is that IB is a manifestation of what you can do with the Obj-C runtime. Of course it's more than a simple exercise to create IB, but the process is simplified by the runtime, and the design of the AppKit classes. I do wish that Apple had of given the OpenDoc team some time to adapt to OPENSTEP, then figure out how to adapt some OD functions into OPENSTEP. Barring this, I hope that some is working on those issues. Instead of worrying about the *complete* functionality of OD, I'd worry about the core of what OpenDoc was supposed to do (*not* what it actually delivered). Perhaps you can express what OD was to give the end user. I think that OD was designed to allow endusers to easily couple programs together. Someone posted an example of auto-scanning photos, processing them with two programs, archiving the photos, changing the photos to optimum size, then placing them into a presentation program. I'm not sure what OD would add that would solve this problem. AppleScript, universally recordable apps, services, and some effort in high level scripting API's would go a long way. Add to this apps that use this scripting strongly *within* the app, even able to save scripts as part of a document, and you go a bit further. Add to this the ability to share views (including some type information for the data displayed). Then include a way for apps to list the types of objects they can vend, along with the datatypes they can process, maybe including if it's a filter or an object to display the data. OpenStep already does this for files, and extends this into services and the pasteboard. If you finish it all up by allowing the program to save files with links to another file, and/or include the data displayed inside the file. Then when opening the file, the app can get the type of the data, request the user prefered view object for the data, instantiate it, and feed it the saved data. (A good example of both methods is HTML, it can include links to other files (images, java), directly embed objects (javascript, visual basic), or links to data with type information which are used to locate the display object (Plug ins). Hmm..you'd still need to add some "auto-coupling", or the ability for two objects to communicate, determine what datatypes they have in commmon (maybe even invoking a translator object), then connecting up. This is the "graph autoconnect to spreadsheet example". The ablity to look up object based upon a datatype is part of this, but something would be needed for the user to find objects. One method is object palettes, another is contextual menus like those from Apple Data Detectors. OpenStep Services are another example (though I don't remember if only applicable services are shown). It still wouldn't be the *complete* functionality of OD, but it may be enough. Apple is committed to some of the above (Scripting), I hope it's added so transparently that virtually every program is scriptable/recordable. Some of the rest was part of things NeXT tried to do (OOE?). I do see lots of places where the lessons learned from OD could be put to some good use. -- Ted Brown tbrown@netset.com

Sure it was. Nobody denies that. You were talking about Visual Basic and components. I brought up IB. Then you said, IB was nothing like OD. Which left me puzzled. NeXT had a rather rudimentary concept for what OD tried to do (links with on-line updating, - looked neat). AFAIK, there was no way to deal with things like: - link some graphic into a text - link this text into a spreadsheet - link this spreadsheet into the former graphic object With OpenDoc gone, Rhapsody will lack a user document component model (which is not at all the same as a component model on the programming level - I'm sure you're aware of that). I heard the blurbs about some JavaBeans stuff, but these are, if I'm not mistaken, vapourware. And, seeing all the energy people put into trying to work out that M$ office stuff, I do not think a good document component model is "too complicated" for Mr. (or Mrs.) Average User.

And IBM didn't deliver the OS/2 version on time. I disagree, I believe OD failed because it was the wrong solution to the right problem. OD required a virutal OS to run in - normal applications had no access to OD parts, and normal applications could not serve OD parts. If you wanted to use OD, you had to "buy into" OD completely, both the user and the developer. You needed OD parts to work on OD documents, both of which were not compatible with any other "classic" application you had. Compare this with the MS solution - flawed as the actual implementation may be. With OLE _any_ application can publish out editors that will work in any other OLE aware application. If you do not have OLE, they are just plain applications. You get OLE support almost for nothing if you try, and OLE applications look and feel like any other application. In a head to head comparison, I have to doubt that OD's object placement abilities, document format, and direct object instantation are better _theoretical_ models, but the reality is that OD war far too different from the rest of the system and very poorly integrated with the normal OS - heck, when I dragged text out of CyberDog, I couldn't open it in Tex-Edit! > OD is failed technology because there is no business model to get rich off > small efficient components.

You need to install the BPF (Berkely Packet Filter) kernel module. Once thats done, you should be able to compile tcpdump (or similar).

From: Weston@icentral.com (Weston Cann) Newsgroups: comp.sys.next.marketplace,comp.sys.next.hardware,comp.sys.next.programmer Subject: Wanted: NS software, advice, hardware Date: Sat, 26 Jul 1997 17:30:20 -0700 Organization: No. Message-ID: <Weston-2607971730200001@annex-slip-00.math.byu.edu> I'm started looking into joining the NeXT/OPENSTEP world a few days ago when I came across some hardware for sale (2 25 Mhz 68040 stations,8 Mb Ram, no HD, 1 monitor, $225. 1 powers up). Since I don't know a whole lot about the specifics of the platform, I've spent the last 48 hours or so reading just about anything I could find online. I've learned more, but I've still got a few questions I'm hoping for help with. First of all, since there's no hard drives included in this offer, and the guy doesn't have a CD with the OS stuff on it, I need to go looking. I'd rather start with something old/used... NS 3.x/Developer or so. I've found a bunch of hardware dealers on the net, but nobody mentioning they sell this. Anybody have a copy they want to sell? Or want to direct me to someone who does? Also, I'm primarily interested in obtaining hardware for the purpose of learning/playing with NeXT development and doing audio/DSP work. What kind of hardware/software is really going to be suffecient for tasks like this? Peripherals & tools? I've read about a "Sound Box" but am not quite sure what this is, and I'm still not quite clear on what development tools are part of the OS package. Finally, if you have some black hardware you'd like to part with around my price range (about $200, but possibly up to the $350 area, including shipping), that you think might fit my purposes, feel free to contact me. And I apologize if any of the questions asked in this post seem to be of a clue-challenged nature. Least I spared you all questions on what I did learn from my days of reading up. Thanks in advance, Weston Oh. One more thing. Anyone know of a history of versions and corresponding features of NeXT/Openstep releases? ____________________________________________________ weston@icentral.com "The best laid plans of mice and men http://www.math.byu.edu/~cann/ are about equal."

All sniffers using the bpf interface should work fine (maybe with some minor changes). I can recommend 'tcpdump' or, if you want a more statistical output 'bpft'. I run the bpft deamon on startup, so I have a full log what traffic is going on in my network, just in case someone is rattling at my door. :-) However if you want to run the majority of available sniffers, tracers, loggers, ... you should consider to play with Linux. -- * Frank M.

The policy I follow, and suggest to others, is don't import ANY header files from within header files defining a class interface except: 1) the header file declaring the class's superclass. 2) any header files declaring protocols which the class conforms to. All other references to other class's should be via the @class directive. - Chris -- _______________________________________________________________________ Christopher A.

There are four fundamental processes that must be running in order for OPENSTEP apps to launch on Windows -- machd, nameserver, pbs (the pasteboard server), and WindowServer. These processes total about 4MB while running (taken from Windows Process Panel). When you launch an app, some additional DLLs for Foundation, AppKit, etc, are loaded as needed. Not all apps need all the kits, so it's hard to calculate the precise impact. I would guess it averages less than 4MB. And of course, once all these processes and DLLs are loaded, they are shared across ALL OPENSTEP apps that might be running simultaneously. So let's say the OS-specific footprint is in the neighborhood of 8MB. These days, that's a $30 SIMM. Also consider this: you get a lot of "free" stuff in that 8MB that makes individual applications a lot smaller. For example, the Windows version of our WriteUp word processor is only 1.7MB. MSWord, by comparison, is 3.7MB. Factor that magnitude of differential for Excel (4.7MB) and PowerPoint (4.2MB) vs their OPENSTEP equivalents, and it's almost equal once all those programs are loaded and running at once. As to runtime performance, my experience is that there is NO noticeable degradation (using long files to stress test, in the case of WriteUp) between the Windows and Mach versions of our app. I think WriteUp "feels" faster than Word running on the same box. YMMV. --- Gregory H.

YMMV. Faster than Word? You wouldn't be saying that PasteUp is dog-slow, now would you? :-) Anyway, one thing I've found is that compositing is about 5 times slower on my NT setup than on Mach. For native-depth blits this is OK, but depth conversions are a killer. For example blitting a 2 bit backing store to a ~ 12 bit native window takes around a second (read: too slow) with NT, whereas it finishes in around 200 ms under Mach (fast enough). Sigh, Marcel

OpenStep/NEXTSTEP/Rhapsody Related Usenet Newsgroups ==================================================== COMP.SYS.NEXT.ADVOCACY This is the "why NEXTSTEP is better (or worse) than anything else in the known universe" forum. It was created specifically to divert lengthy flame wars from .misc. COMP.SYS.NEXT.ANNOUNCE Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. Messages posted to announce should NOT be posted or crossposted to any other comp.sys.next groups. COMP.SYS.NEXT.BUGS A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT-specific groups as well. COMP.SYS.NEXT.HARDWARE Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. COMP.SYS.NEXT.MARKETPLACE NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. COMP.SYS.NEXT.MISC For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! COMP.SYS.NEXT.PROGRAMMER Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. COMP.SYS.NEXT.SOFTWARE This is a place to talk about [third party] software products that run on NEXTSTEP systems. COMP.SYS.NEXT.SYSADMIN Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. ** RELATED NEWSGROUPS ** COMP.SOFT-SYS.NEXTSTEP Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. COMP.LANG.OBJECTIVE-C Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. COMP.OBJECT Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups.

The compiler won't tell you this. [NSThread detachNewThreadSelector:@selector(run) toTarget:universe withObject:nil]; Now think about what this method does: It creates a new thread and in that thread the equivalent of [universe run] will be executed. Any questions left? Answer: No. There's nothing more to it. Do not think one API of one language has anything to do with another API of another language, since they usually don't, not even conceptually. Java doesn't have selectors, and Java 1.0 didn't have Method objects (which basically are selectors _bound_ to a receiver). Hence the requirement to subclass Thread. Will the above work if GCUniverse doesn't inherit from NSThread? It compiles without a peep. Does it run too? If the above is ok, then where do I put my NSLock object? I have other methods in my GCGame object that access variables in the GCUniverse object I just created, so I want to be sure that I can get up-to-date variables... Where do you put _which_ NSLock? Why would you need an NSLock? You don't need a lock only to access variables. Followups to comp.sys.next.programmer since this has nothing to do with comp.lang.objective-C. --Tiggr

New in this release is stability of the language definition, which hasn't changed since the previous release 4.5 months ago. The stability of the compiler and libraries is rapidly increasing, with an 1.0 release to be expected before the end of the year. The attachment below provides basic information on the distribution package. More information on TOM is available on the TOM website, http://tom.ics.ele.tue.nl:8080/, or from the author. Pieter Schoenmakers <tiggr@ics.ele.tue.nl> language: TOM package: tom version: 0.91 parts: compiler(->C), various tools, documentation, examples, test suite, run-time library, libraries, parser generator. author: Pieter Schoenmakers <tiggr@ics.ele.tue.nl> location: http://tom.ics.ele.tue.nl:8080/distrib/ for downloadable source distribution and binaries for selected platforms. description: TOM is an object oriented language developed as a better Objective-C. It doesn't suffer the `C' part (in a way similar to Java) and the `Objective' part is much enhanced. conformance: the C files generated by the compiler need to be processed by GNU CC. The runtime library needs GCC as well; the compiler and some other tools are written in Objective-C. reference: http://tom.ics.ele.tue.nl:8080/ lists more documentation. features: The language promotes usability, as opposed to reusability. To this extent: + classes are extensible entities: a class is fully defined by its main definition and any extensions defined for it, + an extension can add and replace methods. In support of complex added behaviour, an extension can add instance variables. To promote object reusability, an extension can introduce additional superclasses, + extensions can be added to a program at compile, link, or run time. bugs: mail them to <tiggr@ics.ele.tue.nl> restriction: tools: GNU General Public License, libraries: GNU Library General Public License. requires: to build: GNU CC, GNU Make, Bison, Flex, Tiggr's Objective-C Library (available from the same site as TOM) (plus anything needed by autoconf generated scripts). to use: GNU CC. ports: hppa-hpux, i386-freebsd, i386-linux, i386-nextstep3, m68k-nextstep3, ppc-linux. portability: very high: porting to a new machine takes a few hours.

If not, you could do it this way: static NSMutableSet *techs; - init { [super init]; if (!techs) { techs = [NSMutableSet setWithCapacity:100]; } ... return self; } you could do the dealloc like this: - (void)dealloc { ... count--; if ( techs && count == 0 ) { [techs release]; } [super dealloc]; } Though if this is a class var it should only be released when the program terminates, in which case the OS will clean up the memory anyways. -- Steve Dekorte - OpenStep consultant - San Francisco

How does it compare to other middleware? Any real world > testimonials would be greatly welcome. EOF is one of the very best pieces of technology from NeXT. It provides a very complete abstraction layer which allows developers to work at a conceptual layer (dealing with customer objects, stock objects, and so forth) rather than having to deal with writing SQL, managing transactions, and so forth. EOF does all of that for you, and does a better job of managing those resources than many developers can do-- while an experienced DB programmer who spends a considerable amount of effort to optimize database access can do slightly better, that effort would be better spent elsewhere. EOF provides a great modelling tool called EOModeller.app which can query a database and create a sensible schema of relationships from a database, which you can then edit and extend-- creating more relationships, dealing with locking, creating derived data constructs or flattening others, and so forth. > (2) How efficient is it (speed and size)? It's efficient in both terms, since EOF uses a very intelligent caching system for data obtained from the DB using the FoundationKit garbage-collection system. There is some overhead associated with it, of course, which means that EOF is not going to win a "maximum number of transations per second" context, but a major purpose of EOF is to make the client-side more intelligent and capable of manipulating data there instead of always having to bang on the DB server even for simple things. EOF applications don't need to make as many queries to the DB because of the data caching and manipulation capablities. > (3) How robust is it? EOF itself is very robust; EOF applications vary somewhat depending on whether the developers using EOF deal with locking, managing editting contexts (basicly, a bag of changes associated with a particular transaction), and so forth correctly. > (4) How scalable is it? I don't have first-hand experience with very large-scale databases being access via EOF, but my understanding is that it scales up to extremely large situations (terabyte-sized DB's, for instance) and/or accessing multiple databases simultaneously quite well. In fact, EOF is very useful for just that reason, because it allows you to integrate several seperate databases and build relationships between their contents-- even if one DB is Oracle and another DB is Sybase, etc. > (5) Is it difficult to learn? Yes and no. EOF is very eary to learn for someone accustomed to object-oriented programming. But it's a completely different mindset from traditional DB programming-- EOF regards a database as a persistent object store, and the developer creates and works with objects which EOF builds out of the data stored in the database. EOF will let you spit SQL directly to the DB and let you manage connections youself, if you insist on doing so, but that type of thing is not what you want to use EOF for and is the wrong mind-set. > (6) How difficult would it be to provide a C API for existing code? Our > code is built using Sun's cc compiler. The purpose of EOF is to create objects-- EOF fundamentally involves Objective-C. While you can interface between Obj-C and plain C, you want to work with your database using the objects EOF creates for you in Obj-C. In terms of the MVC paradigm, you can use your current C code for the view layer without any problems, but the model layer must be in Obj-C, and the controller layer should be; otherwise, you're simply not taking advantage of what EOF does. > (7) We have a very wide distributed network, and would need to provide > encryption for data that needs to travel over the Internet. How difficult > would this be? Not very, although I think a better solution for secure WAN communication is to use a router-to-router encrypted tunneling approach, which means that _all_ traffic gets encrypted, rather than trying to handle that at the application level. > How does distributed objects technology fit into this? DO doesn't have any direct connection to network- and transaction-level security. In a more general sense, DO allows you to communicate with remote objects exactly as if they were local, which makes IPC much easier and it makes creating applications which communicate with each other much simpler. There are lots of ways that DO could be useful. For example, consider a trading system where there's a big DB containing information about the various positions and so forth. You might use DO so that when a trader does something, anyone else who also was looking at that position will update themselves so that you don't end up with two traders selling the same position, or some other faux pas. Using locking correctly is also important for such a circumstance. -Chuck Charles Swiger | cs4w@andrew.cmu.edu | standard disclaimer ----------------+---------------------+--------------------- I know you're an optimist if you think I'm a pessimist.

Someone else (and now I can't find the message) had a request out for the executable for these for NT. RCS and diff are fairly readily available and CVS builds correctly if you use VC. For everything _except_ wrapped, or binary files, this code seems to work correctly. You appear to need to strip CRs from the NT source although the CVS documentation says otherwise. Does anyone have the whole system working on NT? With binary files the archive files end up corrupt, they have pieces of a number of revisions, and no complete revisions, left in the archive. The version of diff appears to be correct, GNU diff 2.7. The arguments passed to it include a -binary and check in will work correctly if diff is convinced to fail completely. For example, del diff.exe, touch diff.exe - anwser OK to the dialog box that tells you diff.exe is broken and you have one valid revision that can be checked out. The file has only one revision, not multiple, all existing revisions are lost. Anyone have any insight/solutions? Does all of this work correctly with any of the commercial packages? Jim PS Special thanks to Georg Tuparev who's solution on Mach, described in a previous post, appears to work correctly. That is, you need to rebuild RCS with the correct path /usr/gnu/bin so that RCS will pick up the correct diff.

Why don't you just do: : static id techs; : : + new : { : self = [super new]; : if (!techs) techs = [Set new]; : return self; : } Then you compile this with "objc -gc" and, voila, it works ...

I read this book recently. That is the exact name. The authors are Nik Gervae and Peter Clark, both fairly saavy developers who recently worked at NeXT and Sun, respectively, on the development of OpenStep. I thought the book would be extremely helpful to people who are new to OpenStep. It doesn't get very deep, but it's well written and the examples are pretty reasonable. Best of all, it's very current with OpenStep and EOF 2.0, rather than just an upgraded NEXTSTEP book. It does waste some space (but not much) describing features of Sun's OpenStep, which is already a dead product. You can get the book from amazon.com. --Neele

I discussed with my girlfriend this idea and noted some of the specs I want to implement into my App. If you want to add, delete, help or discuss something, I would appreciate it :-) I can write the Mac and PC Versions but every help and/or support is welcome :-) Now a draft of the specs and Ideas I have for my virtual Pet APP: ------------------------------------------------------------ Name: CyberPet or CyberBoz Systems: Macintosh, Windows, Amiga, Newton Shareware or Freeware concept. ------------------------------------------------------------ Basic specs: One-Window based Application which is the Home of the vPet. The Background Image can be changed to different ambients. The real basic is that every App is able to interprete a DNA structure which must be defined (see "The DNA format"). 1.) There is a Bed, Kittchen, Playground, Office and a Door. There are some options in the Window you can click on. With this functions you can interact with your vPet. You can play with him, give food, give Books aso. It could be also thinkable that you can buy thinks like Magazines or Food for your vPet. This must be made in a virtual Supermarket - but is another Idea. 2.) Menu "Pet" point named "wants to Travel" (DNA Export) If you select the Travel Menue in the App the vPet leave through the door and you must select "want to come" to reload it. Is also possible to beam the vPet via Infrared from one Device to another (in the Newton App). From now on you can take this file with you on a Disk or send it via Internet to somebody else - your vPet is Traveling. My Idea is that the vPet can travel from one App to another App. This should be not limited to one Plattform and work in form of a DNA export structure. With this option you can take your vPet with you to work or to a friend. The vPet can visit the vPet from you Friend or Girlfriend. If a external vPet is visiting your vPet in your App there is a chance that you get new vPets with a mixed DNA. But there must be a Male and Female vPet and they have to fall in love. Most of this functions and procedures are RND type and you must have luck to get children vPet out :-) Number and sex of these childrens are also RND. 3.) The DNA format I'm not sure about all the things I want to store inside the DNA. First of all the age of the vPet. I'm also not sure about the source of the first vPet - is there a egg coming with the App like in Creatures or is there only the App and you must find a baby vPet somewhere. (It's also possible that I send you your first DNA by eMail if you are a "good" guy :-) ) In addition to the age there is the sex type, height, weight, eyecolor, haircolor, feetsize and some character specs which handle the control of the vPet. It must be like this: If you feed your vPet twice and it decide to eat, it must become bigger and heavier. Next Day it eat more than before RND controlled. So there could be big and small vPet's and many types of children variations. The same with the intelligence: If you buy magazines and books for your vPet it become more intelligent like a other vPet without these gifts ... and so on ... it is as I said, most of these variations are RND controlled and can be extended in future releases. This is also a major spec in the DNA format that it is upgradeable and downcompatible. Here is also the most room for your suggestions and ideas. I want to have a open discussion about this Idea. Could be great to have all over the World vPets and your vPet can Travel and learn about other cultures. I dont know how to implement this things, but I have many Ideas .. I need also Help from programmers for the Newton App. I plan to publish the DNA specs free and everyone who wants to write vApps like vHospital, vSupermarkets, vFitness and vSport Apps is welcome :-) Is also planed that vPets can cary messages for specific vPets (friends) and there is also a possibility to have a vMarketplace somewhere in the Net. This Idea combines the virtual Identity Idea and the Tamagochi Idea. I need general help from graphic freaks and specific help from coders for the Amiga Version. So, the discussion is opened - hope somebody react positiv on this Idea ?! :-) Regards ... Frank -- Every message from me is a privat statement - NOT from the company i work for!

As I see it, my options would be to use NS3.3 on sparc, or to get Solaris OpenStep. Correct? Is there such a thing as OpenStep for Mach for Sparc? In other words, I understand that I could run the development environment for Sparc, but ideally I would be running the mach kernel with the NeXT BSD layer, etc, on Sparc. Supposing I do use Solaris OpenStep, what does this mean for the applications I construct. How will they run on Solaris? Is some runtime software required to run it on a misc. Solaris machine? I don't know. I must be getting old or something but I'm unable to keep track of what's going on with the "OS Formerly Known as NeXTstep" and Rhapsody and the 30 different development environments for 30 different platforms. Can't they just give it a little squiggley symbol to confuse me a little more? I think the next release should simply be known as: ___ /N e\ \X T/ e-|-<* | v All the different development packages for different computers should have subtlely different symbols.

OK, but that doesn't address the issue of whether or not IB would be suitable as a universally available tool for end users to create dynamic content, which is the point that I'm trying to make. OD documents use the information contained in the bento file to seek out and link together various OpenDoc editors when the document is opened. The end-user never has to worry about the programming details and seldom has to worry about linking the parts together so that they cooperatively share data back and forth. When I drag a webpage from Cyberdog to a word-processor part, all the linking of code is done automatically. If I drag a spreadsheet part on top of a charting part, the code-linking AND the data exchange is done automatically. This is an *end-user* oriented tool. It isn't meant to allow new kinds of applications in the traditional sense to be created. It is meant to allow users to combine user-oriented content in a transparent way. OD does all the code-linking in the background. To the user, embedding the webpage in the spreadsheet looks and feels exactly like embedding a drawing in a wordprocessor window in ClarisWorks. It is a USER-oriented tool, not a programming tool. The actual events taking place behind the scene may be similar or identical to what IB does, but the user need never worry about these issues for the vast majority of tasks that they will use OD for. As I advocated elsewhere, making an OD 2.0 specification that allows for more IB-like functions certainly makes sense, but I sincerely do NOT believe that IB should be used as the basis for creating an OD 2.0. Think of it this way: OpenDoc provides functionality along the lines of the AppKit, but for parts, instead of applications meant to stand alone (although virtually any OD part can be used as though it were a standalone application). Instead of talking about IB being the functional equivalent of OD (there is overlap, but not as much as you appear to believe -*I* believe), we should be talking about how to make the Yellow Box architecture completely component-based. Any app running in the Yellow Box should behave as though it were an OD part -able to embed or be embedded-in other parts. When Rhapsody apps are exported to non-Rhapsody systems, they should function as standalone applications. There should also be a provision for Yellow-box-only components that do NOT export to other systems. These would be lighter-weight parts along the lines of Java Applets, JavaBeans or the less feature-bloated OpenDoc parts (like I understand Brad Hutchings' parts to be like). Rather than saying "oh, gee, IB/NeXT can already do much/most of what OpenDOc does, but in a different way," why not acknowledge that OD has a great deal to offer Rhapsody as far as parts-nesting/interaction/GUI issues go, and work on designing a hybrid that combines the *complete* functionality of OD and the *complete* functionality of the AppKit and whatever IB has to offer that is appropriate for generic components? While not as easy-to-use/program-to/etc, the utility of OpenDOc and the ODF are greater for most end-users than the utility of the AppKit and IB in those areas where components are concerned. Why not merge the two frameworks using an embracing philosophy, rather than talking about "tacking on" *some* of OpenDoc's more trivial features? Rhapsody should become GREATER than MacOS + NeXT, not just be NeXT + one or two bits of MacOS. I want Rhapsody to become OpenDoc on steriods, not merely Just Another Framework that Microsoft will eventually imitate. Microsoft will NEVER imitate OpenDoc. OpenDoc allows Office-like products to be created out of masses of 3rd party products purchased seperately by the end-user. Microsoft can't afford to allow that to happen. OpenDOc was *designed *specifically** so that that could happen. Was the AppKit? Was IB? ------------------------------------------------------------------------- Build a better mousetrap, yes, but then market it like crazy, or instead of catching mice you'll only collect dust. -David Yeargin -------------------------------------------------------------------------

But to limit the size of the possible I think it would be a good (better?) idea to mimic real life and make the "DNA" part only store the characteristics and instincts of the creature, not stuff like age, etc which is a parameter of the individual body that the DNA resides in. As well as allowing the pet itself to travel, why not facilitate the meeting between two pets to produce offspring with a combination of the parent's DNA. If you also allow for DNA "mutation" (i.e. random copying errors) then you'll have the basis for natural selection to take place. The selection will work automatically by the appeal of the vPet to a particular user- "nice" vPets will tend to succeed where "nasty" or useless ones won't. After a time the vpets will take on a life of their own and "evolve" in unexpected and astonishing directions. Obviously to do this the basic protocols for turning the DNA into a body (phenotype) need to be established and based on very simple rules. The first vPets may be rather unsophisticated and perhaps virus-like, but eventually more interesting ones will arise. Go to it! +G+

Even the local sales men couldn't/wouldn't answer that one in a satisfactory way. From what I gather, the Solaris OPENSTEP development environment is available and should be fully OPENSTEP complient (i.e. the programs should be compilable on OPENSTEP for mach 4.x and OPENSTEP for NT/95). I'm quite sure that you'll need a runtime environment to run OPENSTEP programs, however, you certainly don't need the OPENSTEP desktop. > I don't know.

Starting with 3.1, the intel platform was added. Then, with 3.2/3.3 the HP and SUN computers came along. This was always the mach kernel and BSD environment. At this point, NeXT started porting NEXTSTEP development environment to WindowsNT and, together with SUN, defined the OPENSTEP standard. While SUN developed the OPENSTEP for solaris, NeXT continued with the mach and BSD environment, calling the product OPENSTEP for mach, and also with the WindowsNT product, calling it OPENSTEP for windows. > Furthermore, anybody using the name 'OpenStep' should be sued by Apple.

You need to set your code up as the NSTextField's delegate (connect the delegate outlet of the TextField to your delegate object) and you will then receive controlTextDidChange: messages for each keystroke. (See the documentation on delegate methods for NSControl and NSTextField.) Usually when you want to be notified of state changes in any kind of control you receive these notifications through the target/action paradigm of controls, through delegation, or through NSNotifications. These 3 paradigms make it unnecessary to sub-class just to perform standard functionality. - Chris -- _______________________________________________________________________ Christopher A.

Not hard at all. As an example, many programs in the NeXTSTEP/OpenStep realm implement an "inspector" window, which can stay up all the time if the user desires, and every time the user selects a different object the inspector window is updated to reflect information about the currently selected object. -- Stephen L.

One nice thing about OpenStep and Objective-C is that you accomplish many tasks without creating a subclass, but instead by using delegation. A good use of delegation is to adapt the behavior of a general purpose object (say a UI control like a text field) to a particular context (say your app). This way you don't get a slew of specialized NameTextField, and AddressTextField classes, and more importantly, you separate general purpose reusable code from special purpose context dependent (less) reusable code. Delegation is described briefly in the Object Oriented Programming and Objective C Book. In a nutshell, the idea is that the general purpose object, sends messages to a delegate object (if it responds to them), notifying it of important events and delegating some responsibilites to the delegate. The set of delegate methods is fixed at design time, but how you use them is up to you. Its sort of like building in hooks or callbacks, but more flexible. Another related design pattern is the Model-View-Controller paradigm, of long use in the SmallTalk and NeXT worlds. (We used patterns before patterns were cool :-) With MVC, you separate strictly the UI classes and the business area classes, keeping all domain knowledge out of the UI (the view layer) and all UI knowledge out of the domain classes (the model layer). This way you can reuse either independently among other benefits. You glue the two layers together with a Controller object that is the only one that sees both layers, shuttles values between the layers, and responds to user events. Given that you've pushed through all this, the best way to catch keystrokes in most OpenStep situations is actually pretty simple. Set your controller as the delegate of the textfield in IB. Have it implement the appropriate delegate method. Look at the end of NSControl and NSTextField docs to select the one you want, and do what you wish with the keystroke. Its usually quite simple to get notified of UI events. In this case there can be some complications since all text fields on a window share a common text object for editing to conserve memory - called the field editor. Also there are a series of delegate methods sent, in specific orders, that may interact. You may need to experiment to start to see what the effects are. This is usually the best way to go with OpenStep. Creating a UI subclass is sometimes the right approach, but much more often delegation (or notification) is the easiest path. -- Alex Blakemore alex@genoa.com NeXT, MIME and ASCII mail accepted

IMHO BOTH ways are dead ends - I hate to say it, but if you like to do serious work - forget the SPARC platform ! 1) OPENSTEP for MACH for SPARC processors It's exactly the same than OPENSTEP for MACH for the other processors (x86, m68k) you won't notice a difference. BUT: OPENSTEP for MACH won't be supported any longer and will become Rhapsody. So far I haven't seen any sign of a SPARC version of Rhapsody. Another problem is, OPENSTEP for MACH/SPARC does ONLY run on microSPARC-II and superSPARC processors, no hyperSPARC, no ultraSPARC, no turboSPARC !! Sun doesn't offer machines with micro- and superSPARC processors anymore. And here's another problem, if you go with OPENSTEP for Mach: you can't use any Solaris 1/2 programs wich is unaccaptable in about 90% of all cases (running a 3rd party operating system instead of the vendor's OS is not very reasonable) 2) OpenStep Solaris I haven't got a proof from Sun, that they dropped OpenStep Solaris, but it seems so and I tend to believe it. If it's true, this was IMHO Sun's (or Scott's) stupidest decision. OpenStep Solaris made Solaris user friendly (for the first time [forget OpenWindows]), and if you want to attack the PC sector (and Sun will at the end of the year) you have to have a GUI, that beats Windows to make your better OS acceptable for the (standard PC) user. I can't see anything from Sun that fills that gap (using a browser as THE GUI is a joke, IMHO). However, Sun's existing Solaris OpenStep 1.0 cannot compete against OPENSTEP for Mach or Rhapsody. It implements ONLY what's defined in the OpenStep Standard draft 1.0 from 1994. All extensions from NeXT/Apple (new classes, Textsystem, QuickTime,....) are not usable for OpenStep Solaris which makes porting Rhapsody or OPENSTEP Apps impossible (it's more a rewrite) - yes in theory it should be easy, but that's marketing. OTOH Solaris OpenStep needs much more improvment than the missing extensions from NeXT/Apple, it's buggy (but not unstable) and first of all damned SLOW, compared to NeXT's implementation. Conclusion (IMHO): The only reasonable way for developing OpenStep/ Rhapsody Apps on SPARC would be using a NEW version of Solaris OpenStep that can compete with Rhapsody in terms of features, speed, and quality. This would open the SPARC platform for all new Rhapsody Apps (if Sun wants to go into the PC sector, it needs more that good hardware and a good OS, but user apps [ask NeXT about that lesson]) and could make NT less attractive than it already is. BUT, this is wishful thinking and I don't believe it will happen... ...maybe because some people drink too much a kind of coffee... Patrick.

Once the user has made enough Text Object selections for the app to proceed, I'd like to send the cursor to a button and have it wait there for the user to click on it. How can I do this through system events ? I have seen how DrawApp catches certain events and processes them aside from the regular event chain (by overriding NXApp's sendEvent: and catching them there), but for my purposes I think it more simple to repackage the current event structure with my specific modification to the cursor's position and send it back as a new event. I am unsure, though, about 'where' or how to send it. I get the feeling I'm overlooking something. Thanks for any help -- Chris

How does it stay in scope? Sorry, i'm pretty new >to objective-c. The question of the scope of tooLate is not specific to ObjC. This is a Standard C feature. static variables are normally in scope for the current file, but static variables declared within a function are only in scope within that function. Another angle on this is that while automatic variables will go away each time you leave the function, because the stack space is reused, static variables are not allocated on the stack and can therefore will still be holding valid data the next time the function is entered. It is somewhat confusing that automatic stack variables and function-scoped static variables are declared in the same place, but the keyword static makes all the difference. For the purposes of the above explanation, I did not use the ObjC term "method" because a method is really just a function with a couple of extra hidden parameters. In most respects they are the same, including the above discussion of the scope of static variables. -- Brian Willoughby NEXTSTEP, OpenStep, Rhapsody Software Design Sound Consulting Apple Enterprise Alliance Partner NeXTmail welcome

I ADD YOUR NAME IN THE PROGRAMMERS LIST AND I WILL CONTACT YOU IF THE DEVELOPMENT STARTS. YOU WILL RECEIVE THE vPET SDK KIT FREE WITH ALL INFORMATIONS AND FORMAT DESCRIPTIONS. vPET IS YOUR APPLICATION! to Basic specs: I forgott to say that vPet is a game charactered App. Even if there some functions which points to a economic simulation App it should be a GAME ! But the simulation effect is automaticly coming if the vPet is RND controlled :-) More and more i get the impression that this project would be a great game also for childrens. They can learn how to handle with money, how important is health and who to find friends and a partner. The vPet can smoke but then it reduce the health status :-) to 1.) The possible Playgrounds for the vPet A idea from Daire Garvey is to have your vPet on your webpage in a Java applet. Sounds good but then it must make a sence if the vPet is there. Lets play with the Idea: If you transfer the DNA to a vPet Server there must be a possible function for the vPet like searching for a partner or collecting informations. A thinkable way could be to have defined categories like "Go shopping", "do Sport", "make Hollidays", "search a partner" etc. Inside this categories the vPet have a order; like "buy food". If now a other vPet has the needed information or the needed product your vPet is buying/recieving it and stores it in the order field. If now the vPet returns to home it puts the food into the refridgerator and communicate it to you. If the order was to make Holliday and he returns the DNA is modified and the life quality standart is increased or decreased. This adds the question to the project if we need vMoney. How do the vPet pay for Holiday or in the Supermarket ? How do you buy Books for it ? But if we add vMoney we need a vBank, vCreditkard etc ... :-) We can solve this problem if we have a function implemented that give us the possibility to spend our vPet every Month some pocket money and the vPet stores it in the DNA.pocket_money or put it on a vBank. The DNA.bank_number var is important if your vPet wants to buy something on Credit somewhere. If somebody wants to create a vBank he must register it and receive a bank_number. But first we must think on the makeable things. I must shrink the possible interactions in the first release because i dont have the time to implement all ideas :-) to 3.) The vDNA format - VPTP (Virtual Pet Transfer Protocol) Ok, the vDNA format is now the major interrest. I think that the numbers of variables must be expandable for future updates. But to limit the size of the possible vars there must be variable field list with a value range header. That means that there must be libraries (vDNS) which hold the value ranges and there description. The vDNA only represent numbers which access the values inside the vDNS. Is like in real life - there are many combinations possible with only 4 values. Every vDNS has a unique Number which is generated by the main App. The unique part is controlled by the user registration which gives various numbers. Every vPet is registered and everybody can check the popullation state in the web. The registration of your vPet is FREE! Is only to handle the statistics. It could be very interesting to see how many vPets still life and how many are death. If a vPet dies it must be also registered and the name is deleted in the main registry. Btw, it's also thinkable to build vCommunities and vCountries. Functions of these Instances could be to define the life conditions. The life conditions help to handle the DNA.health_state. But this is a future point :-) Example: def type format current_feeling (0,1) as integer current_actualtime as time (stores the export time if the vPet is going to travel) age_birthdate as date height_cm as byte weight_kg as byte sex_type as bolean (true=male, false=female) health_state (0,1) as integer eye_color as byte hair_color as byte feet_size as byte pocket_money bank_number ... character_specs as ??? (still thinking about this point) ... end type dim vDNA as type format Settings: vDNA.current_feeling(0,0) = 1 rem first position of the value range of the feeling DNS which can be from -10 to 10. vDNA.current_feeling(0,1) = 5 rem the 5 is the used value The benefit of this methode is: If we want to extend the possible combinations we can expand the value range inside the DNS library 1. 3.1) NEW - The vDNS format The vDNS Library format is a list of value ranges and their format. The vDNS is handled by the main App and is not transfered. Only a way to update the vDNS must be there. Example: def type format description as string * 30 range (1) as integer end type dim vDNS (x) as format vDNS.description = "Feeling state" vDNS.range(0) = -10 vDNS.range(1) = 10 Something like this should give us a max. of variations. I'm not sure if we should use the description only as description or also as a identifier for a interpreter. I mean, if a other Version of the DNS Library has a other value range in position 1 it must be possible to search inside the field for the Feeling state. 5.)

Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. COMP.SYS.NEXT.SOFTWARE This is a place to talk about [third party] software products that run on NEXTSTEP systems. COMP.SYS.NEXT.SYSADMIN Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. ** RELATED NEWSGROUPS ** COMP.SOFT-SYS.NEXTSTEP Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. COMP.LANG.OBJECTIVE-C Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. COMP.OBJECT Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups.

You will only need one class; a subclass of NSObject that will contain all of your custom behavior. It will be simple; one method to update the status information-- this method will be an action method so that you could have, say, an update status menu item. The Main Window and child status window would be in your main InterfaceBuilder NIB file. In this NIB file, parse the header for your subclass of object-- then create an instance of that class and set all window's delegate to that object (as well as the app delegate). The only code you would write would be either an action method that is activated upon opening the child window or a window delegate method triggered by the child window becoming visible; this methed would simply update the child window's display [if the status display is as simple as a text field, this would be a single line of code + whatever is required to determine the status]. Since it sounds like you only need one editing window, your editing window can be in the main NIB file, as well. No code to make it visible; just add a menu item to the main menu and connect it to the -makeKeyAndOrderFront: action of the editing window... To update the status window form the editing window is equally as trivial. In your editing window, if the user only enters one piece of data, connect the action of the field to the action method defined in your subclass of NSObject. Your done.

Date: Mon, 11 Aug 1997 14:35:12 -0600 From: mvitalo@sprynet.com Subject: Enterprise object modeler and OpenStep in general Newsgroups: comp.sys.next.programmer Message-ID: <871327633.3613@dejanews.com> Organization: Deja News Posting Service Does any know where I can get documentation on the Enterprise Objects Modeler that is in OpenStep? We have looked at online documentation that next provides and have not found any. Also, if anyone has used this, could you tell us about your experience and what you liked/disliked about it. I work for a startup company in Austin Texas. We are evaluating cross platform development enviroments for building the next generation of our product. We have become interested in the possibility of using OpenStep. But we have some questions that are hard to get answers for and I am hoping someone can help us. Our questions loosely fall into the categories of performance and libraries. With respect to the libraries that Openstep provides: 1) Do they all work on every platform that Openstep builds for, or are there limitations? If there are, can you tell us where to learn about them? Or better yet, can you tell us what they are? 2) Are the libraries only available in Objective C? I ask this having read the literature from Next, they said that development could be done in C++. 3) If the libraries are only in Objective C, do you know what mechanism is used for linking C++ and Objective C? 4) What is lacking in the libraries, that is, what do we have to supply outside the obvious design and code that is specific for our app? What I'm really asking here is do we need a strong knowledge of each platform that Openstep builds for? And are we responsible for, and is it required of us, to modify parts of our code for each platform? I expect this to be true, to what degree is what I need to know. Performance is critical for us also, and so we are really interested in the code that Openstep compiles to. We have some questions on the compiler(s) that Openstep uses: 1) What are they? It is my understanding that Next uses the GNU Objective C compiler, with modifications they made. Do they also use that compiler for C and C++? 2) How does the code produced compare with compilers from other venders? Specifically, on the WinTel platform, how does it compare with compilers from Borland, Microsquash, and Watcom? 3) Can you link in assembler? This is not very cross platform'ish, but it gives me an idea of what we are looking at. The real question here is does Openstep provide all the optimization that we come to expect from our WinTel compilers? Our worry is that with the impressive generality that Openstep provides there is a hit in performance. This is what I would expect, but I'm hoping you know. I know that the code that the compiler produces can really have no influence on the performance of the application if it is poorly written. We are continually improving our application and don't want to find out that we need to move to another compiler because Openstep can't deliver on the performance needed. Some other questions we have are: 1) What size and type of application have you built using Openstep? 2) What other applications do you know of that have been constructed using Openstep? 3) For deploying across platforms, how do you construct your installation programs? Does Openstep have an installer? We are Windows developers so our knowledge here is limited to WinTel. 4) How do you write help? Does Openstep provide a tool for this or do you need to get separate tools for each platform? How is that help file then linked to our executable? I expect that this depends on the platform, but I want to know if this is something Openstep takes care of too. 5) Have you or do you know of anyone who has constructed OLE components using Openstep? 6) How well does Openstep connect with an OLE object? Is this easily done? We would like to use our existing interface, written in Delphi, and link this to an Openstep back end. To do this we expect to convert our interface to a OLE object and imbed it in an Openstep application. 7) Is this a reasonable thing to do given your experience with Openstep? We then expect to build the interface in Openstep and move across platforms later. 8) Have I killed you with to many questions? 9) One last question, does it still support Hp unix and sun solaris? -------------------==== Posted via Deja News ====----------------------- http://www.dejanews.com/ Search, Read, Post to Usenet

Weird. I haven't actually used 4.2 release for NT, but I have been used 4.1, 4.2PR1 and 4.2PR2 and while it wasn't 100% stable, it doesn't seem to be as messed up as it is for you. The one thing I've found that'll screw up the NeXT stuff every time is for TCP/IP to be messed up, especially DNS. I somehow doubt that's your problem though. :( Maybe I'll try installing 4.2 final to see if I get the same problems. -Ken -- Kenneth Dyke, kcd@jumpgate.com (personal), kdyke@ea.com (work) Nuclear Strike and OPENSTEP Tools Engineer, Electronic Arts C++: The power, elegance and simplicity of a hand grenade.

Make sure you select "alternate IDE setting" in the Virtual PC Preferences dialog. You'll need to page down to the ETAPI/IDE option (if I remember right) during the install.

Don't do that ! Life is a little simpler if you leave NSApplication alone, and instead create your own AppController class (for app wide stuff only) and make it the NSApplication's delegate. Then have DocumentController's for each kind of document that your app manages. Try to minimize communication between controllers, so that there are few dependencies between them (allows you to shuffle things around easier if needed) The typical reason to subclass NSApplication is if you need to add logic around the event loop by subclassing sendEvent: Some classes in OpenStep are big and complex with lots of hooks to adapt them to different contexts (delegate methods, notifications, setBehavior methods) Often such classes are complex. Its usually much better to take advantage of their built in hooks to adapt their behavior than to try to subclass them. That way you don't have to worry about understanding or disturbing their internal behavior. NSApplication is one such class (NSTextView, NSTableView are others.) You can subclass these things, but it can be tricky, and there are almost always easier ways to accomplish the task at hand. This rule of thumb might not be as strict as it was with earlier NEXTSTEP, but its still probably worth following. (It sounds like the answer to your problem is to name your custom NSApplication subclass in Project Builder's project inspector so it will create a proper main program.) But I strongly recommend not doing that. Please be aware that Draw is an old example, that has passed through lots of hands, and exists mostly to show off various features of the system (its a kitchen sink) It was designed with older NeXTSTEP. Its not necessarily the best model to follow. -- Alex Blakemore alex@genoa.com NeXT, MIME and ASCII mail accepted

I had already discovered my oversight about the project inspector, but I like your idea of moving to a delegation-based design. Moving from a subclass-based viewpoint (Object Pascal & C++) to the Objective-C viewpoint will, I suspect, take me a little while. But that's why I'm spending the time and money to learn the OpenStep environment. Frank Alviani

Welcome Vernetta 18. Be OS Ported to Intel 19 . Subscriptions Now Available 1. OpenStep Newsletter is Back in Production I have hired a second person to help out with the recruiting function, allowing me to focus on publishing the newsletter. That should mean more regular newsletters, with deeper coverage. At the same time this newsletter needs to distinguish itself from other web publications. Every newspaper is now covering the board room antics at Apple, so to provide unique value to my readership, this newsletter will focus on the object technology at Apple, namely OpenStep, WebObjects, Rhapsody, EOF, and Java. Other Apple news will be covered only in passing. 2. Rhapsody has Spreadsheet, Word Processor, Graphics Applications Three different companies have each announced one of the key office productivity applications for Rhapsody. P&L has ported the Mesa Spreadsheet <http://www.plsys.co.uk/plsys/>; Anderson Financial has ported the Write Up wordprocessor<WriteUp@afs.com> and the PasteUp <PasteUp@afs.com> layout manager; Stone Design has ported the Create the "total design studio with web page capabilities" <www.stone.com>; Caffeine Software has ported the Image Processing Tiffany application; Metrowerks is porting over their lattitude library; And some of the mainframe connectivity applications are ported over. These and other applications were ported to the newest release of Rhapsody at the developers kitchen just before the Boston MacWorld Trade Show. As a company that runs happily on NeXTStep 3.2, I have to say that there is a lot of software <ftp://ftp.next.peak.org> that runs on the Mach Operating System, most of which simply cannot be ported to Rhapsody until the Rhapsody developer release becomes widely available. 3. Music Kit Lives Many years ago, NeXT dropped the MusicKit due to lack of commercial demand. NeXT then licensed it to Stanford. More recently Yamaha and Stanford licensed patents and software to a joint venture called Sondius. <www.Sondius-XG.com> The first licensee for Sondius is a company called Staccato Systems. <www.staccatosys.com> The MusicKit offers a computational model of sound generation and allows the application developer to create a particular instrument as a specific instantiation of the generic physical models. Instruments could be traditional musical instruments, such as a piano, or a more abstract sound source such as a door that slams or any other video game sound. These instruments can then be driven by music notes which can be transmitted as midi. Midi represents sound as a series of notes, and allows for 128 (7 bits) instruments to play those notes. Midi only allows the definition of 128 musical instruments, so Sondius is attempting to define an extension to the Midi standard. Of course in the Stanford Newspaper article about the technology, no mention was made as to the source of the software, or that it was implemented in Objective-C. 4. RTF to HTML Conversion. If you have rtf or rtfd files that you want to convert to HTML try LatinByrd. <http://members.ping.at/stefan/> TIFF and EPS images in RTFD docs are automatically converted to GIF, JPEG, and PNG format. And unlike some of the other OpenStep HTML generation products, it works just fine on NeXTStep 3.3. LatinByrd works by reading the RTF file into an object from NEXTSTEP API's 'Text' class. LatinByrd then takes that Text object apart, gathering all the necessary layout info from it and saving out the HTML file. Since the Text class doesn't know of Microsoft style sheets LatinByrd does not parse that information correctly. 5. Java on Rhapsody Java will be the primary development environment on top of the Yellow Box. Existing developers who hear this worry that Objective-C will no longer be an option, but rest assured, that the wizards of the world will have access to incantations not available to the novices. 6. Metrowerks Porting Latitude to Rhapsody The Latitude library implements the Macintosh Applications Programming Interface (API) on Unix. It is now used by Macintosh developers to port applications to Sun's Solaris, and in the future will be used to port to Apple's Rhapsody. Metrowerks is porting the Latitude application to Mach on Intel as a stepping stone to Rhapsody on PowerPC. Metrowerks will then port their own development tools to Rhapsody. Already they have integrated the GNU compiler into their development environment. Metrowerks is also developing a C++ compiler for Rhapsody. Alas, Metrowerks is very much targeting the embedded systems market, rather than the corporate, object-oriented development market. Thus their tools emphasize code performance over flexibility and reusability. Don't expect nib files from Metrowerks initially. Their code saves time and space by writing subroutines that generate the desired User Interface. Sigh. 7. Java Bridge Apple is working on a Java bridge to allow Java client applications on other platforms to talk to Rhapsody servers using something like PDO. More details will follow next month. Meanwhile take a look at a technology for building Java clients to Web Objects <www.advis.com> Does anyone have a better solution for connecting Java Clients to Objective-C servers? 8. Persistent Java I know two companies that are selling persistent Java. O2 <www.o2tech.com> and Servio Logic <www.gemstone.com> Of course there are many more companies selling Java language servers connected to relational databases. Even the persistent Java vendors connect to relational databases, but why bother. With persistent Java you get database persistence, in a nice message-passing based environment. What else could you ask for? Let me know what your experiences have been. 9. Apple Focused on OS not Development Tools There is a huge change over at NeXT/Apple. They used to be a company targeted on corporate mission critical applications. Now they are a hardware vendor trying to ship an operating system. Even the sales of WebObjects at the $80-100 million level pale in comparison to the sales of hardware at the $8 billion level. 10. Microsoft Invests $150 Million in Apple In addition to investing in Apple, Microsoft also agreed to upgrade Microsoft Office on Macintosh for 5 years, in exchange for Apple agreeing to bundle Internet Explorer with the Macintosh Operating System. Effectively Microsoft and Apple are downplaying the competition between their operating systems, and Apple is joining the Microsoft camp in the browser wars. Note that Microsoft cannot afford to allow Macintosh to disappear, for then they would be highly subject to monopoly busting federal law suits. The stock market reacted favorably to this news, presumably because it stabilized the life of the Macintosh; but OpenStep developers fear that it will reduces the pressure on Apple to migrate to Rhapsody. Apple had been trying to move to Rhapsody ASAP as a competitive strategy against Microsoft. Now that they are on the same side there may be less urgency to migrate. OPENSTEP JOB MARKET 11 a)Introduction If you are interested in any of these positions, send email to lozinski@openstepnews.com. I not only place people, I also advise them on what type of company to select. I help individuals find environments that suit their personality type. Everyone ends up very happy with the placements that I make. 11 b)60 Hiring Managers My database now includes 63 OpenStep hiring managers whom I personally know. If you are looking for a particular type of job, one you don't see here, I would be happy to send your resume to the right hiring manager. I know more about these companies than the average individual knows, and am able to tell at which company a particular person would find a compatible work environment. Current openings include: 11 c)Seattle Fast Growing Company This company has passed through the start up phase, and is in the high growth phase. They have contracted with the OpenStep newsletter as a sole source of WebObjects developers, and are paying premium salaries and stock options for experienced OpenStep developers. I am proud to say that these positions are only available through the OpenStep newsletter. 11 d)Washington D.C. Shrink Wrap Vendor Washington finally has OpenStep jobs that are in the commercial product market. This company is successfully building a shrink-wrapped product on OpenStep. Pretty exciting stuff. They have seven major customers already and are on a roll. T hey have an interesting Human Resource Policy. They are looking for cooperative individuals. Several Empire builders were recently laid off, because they interferred with the matrix management (read networking) within the company. Furthermore they want people who love Mach but have come to terms with the market acceptance of NT until such time Rhapsody becomes an acceptable alternative. I personally know the hiring manager. He is great at managing projects, and developing and following a plan that meets the customers application requirements and scheduling requirements. 11 e)Become a Java developer If you are interested in Java, but want to work with a group that understands good Object Oriented Design, then let me submit you to this group. New York or Bay Area Location. I will be meeting with the hiring managers on Wednesday 11 f)San Francisco Bay Area NeXTStep If you love Objective-C, you will love this job. Develop on NeXTStep with no WebObjects in sight and NT nowhere around. 11 g)San Francisco Bay Area: Learn NeXTStep This company is willing to train computer scientists in NeXTStep. 11 h)New York: Know Perl, Learn WebObjects This company is willing to train a beginner NeXTStep developer who knows Perl well. It is a great way to get paid to learn NeXTStep and EOF, and WebObjects. They prefer people who prefer stock options. 11 i)San Francisco WebObjects Storefront This company is looking for developers who have experience building an Internet StoreFront in WebObjects. Work from your home city anywhere in the world. 11 j)NeXTStep System Administrators For a long time the market demand for NeXTStep system administrators has been dead. Now it is starting to come to life, as people are reinvesting in Mach, and planning on Rhapsody. I now have two clients looking for System Administrators, and I expect to get more soon. 11 k)Auspex System Administrator Needed It has been a long time since a client has asked me to find a NeXTStep system administrator. This is a scarce position. If you know auspex, you should jump on this opportunity immediately. 11 l)San Francisco Bay Area NeXTStep System Administrator There is a job for a nextstep system administrator in the San Francisco Bay Area. The company is really focussed on taking good care of its staff, and running the organzation as a network of individuals. For someone who knows NeXTStep 4.1 well and NeXTStep system administration, this is a great opportunity to learn more about networking. Let me know if you are interested. I believe that they will even take foreign candidates. 11 m)Texas Great Family oriented company. You get a lot of house for your money here. The company also has a great comp time policy. If you have to travel at all, all those extra hours are comp time, and when you get back you can take a day off work. Pretty cool benefit. This company has a serious need for 6 senior developers and are promising to fill these positions promptly. This is the company for developers who want to move to Texas. If you want to break into the Financial Applications market, then this is a great opportunity. If you know NeXTStep but need to learn EOF or WebObjects then this company may be willing to give you high value training. 11 n)San Francisco Bay Area The company has an overly large existing application that needs to be migrated to a more solid object architecture. You will be responsible for conceptualizing the desired architecture and evangelizing that approach to the rest of the organization. In the process, you will encounter other points of view. An ability to win over and co-exist with other perspectives is very important. Sensitivity to others' concerns is also very important. Located in the San Francisco Bay Area. 11 o)SnowBoarders Needed If you are into snowboarding, then join the company putting up the definitive Snowboarding Web Site. Fringe Benefits including paid weekends to evaluate the products being resold. These guys go steep both in Snowboarding and in business, so get ready for the ride of your life. San Francisco Bay Area location with offices planned in Colorado, Switzerland, 11 p)Deep South Quiet rural location is the headquarters for an Internet Systems Integrator who loves NeXTStep. The other person I placed there loves the job. The boss tries to insert OpenStep and WebObjects in his own billing system, and whereever his customers let him. 11q)Boston, Washington Consultants Are always needed. One of the projects is very well designed and exciting, one has no design and is in complete confusion. The last one is so large, that changes can only be made very slowly. Of course these are consulting positions. 11 r)Midwest Your boss will be one of the original NeXT Developers. This is a great place for a beginner to solidify his/her grasp of NeXTStep. It is also an interesting application. The company is building customer support software for an Internet service provider, so you also get trained in the intricacies of Internetworking. 12.Tom Love, the Businessman Behind Objective-C Tom Love founded Stepstone with Brad Cox. While Brad developed the original version of Objective-C, Tom made the sales to finance the development. Later as C++ rose to take market dominance over Objective-C, Tom voted in favor of offering both C++ and Objective-C services, was voted down, and left Stepstone. Without his drive and market savvy, Stepstone dwindled into insignificance. Tom went on to offer consulting services, wrote a book "Object Lessons", and helped create IBM's Object Technology Practice. In March of this year, I received a call from Tom asking me if I could find good Objective-C developers that he could teach Java syntax to in a week. This was a hot project, and so on a next-day service basis, I found him the people to develop and test his application. With my usual great intuition, the people I found for him fit the bill exactly. The senior developer of this financial analysis project had spent his whole life doing time-series data analysis; although the applications were in physics, these were skills easily transferred to Wall Street. The junior tester came from a school that aggressively emphasized testing. The pair of them cost the client significantly less than had been budgeted. On July 23rd Tom's application made the Wall Street Journal, front page of section C. In about two weeks, the application will go public and lose password protection. (See <www.riskview.com>). Impressively enough, the application went from design to delivery within 100 calendar days with just three developers. It is not a simple application. Good design, and great management will do it every time. Yes, I take credit for shaving a week off the cycle time with my superior quality recruiting services, but the real applause goes to the great NeXTStep developers who know how to design object applications, and in this case outranked the functional decomposition camp who had a different design approach. The key to good design is flexibility against the unexpected changes that lie ahead. In one instance the team needed to change the time-series analysis from daily to weekly. With a single subclassing, and 15 minutes of work, the change was made, and everything else worked. Tell your boss: OpenStep developers make the best Java developers. They are the only ones in the world with 5 years of Java design experience. 13. Senior Project Managers Available Do you need a Java application delivered in a hundred days? Is your software project over budget and behind schedule? Do you have a critical deadline to meet? If so, I know a number of people who can help you out. These are older, very experience project managers who understand Object Technology, Customer Requirements and Schedules and can integrate them together. These people are also very politically savvy. The basic offer is that you tell them what you need, and they tell you what it takes to accomplish the objectives and the schedule. You give them full authority over all relevant issues, and they deliver what you need. They all have extensive track records that show their ability to accomplish what you need. 14.OpenStep Newsletter Changes Focus The Tom Love project and the huge growth in the WebObjects market have changed the business focus of the OpenStep newsletter. We started out placing average OpenStep developers into corporate positions. We are still doing that, but it is clear that our great advantage is in knowing the best OpenStep developers. My database is filled with exceptionally experienced (4 years or more) OpenStep developers, senior project managers who have proven their value and productivity. If you would like to hire one of these talented people, please let me know. 15.Newton and Emate The Apple Newton and the Emate run the same operating system. It is a modern operating system with a self-like language which runs in minimal memory space. Apple is selling out as quickly as it can manufacture them. Mostly they are selling large shipments to vertical market segments. It would make a great basis for a low-cost network computer. Larry Ellison are you listening? 16.Big Changes in Smalltalk Market Before the arrival of the Web, ParcPlace's Smalltalk provided a very attractive cross-platform solution for corporate applications. Since then, the Web has made Smalltalk less interesting. HTML runs everywhere for free. ParcPlace Smalltalk runs almost everywhere, but costs a lot. In the mean time, ParcPlace had purchased their arch competitor Digitalk and attempted but failed to merge the two products. Eventually they put the Digitalk product on the back burner, and most of the customers fled to IBM Smalltalk. The net result is that ParcPlace was recently trading at a dollar a share, probably close to their asset value. 17.Welcome Vernetta Vernetta Wilson is now working with me.

A comprehensive list is available on Stepwise. Stepwise OpenStep/Rhapsody Information Server http://www.stepwise.com Stepwise has been serving the OpenStep/NEXTSTEP community since March 1993. Some of the many resources on the site include: OpenStep Third Party Software guide, Developer Directory, Mailing List information, extensive listing of FTP and WWW sites related to OpenStep and NEXTSTEP, OpenStep related Frequently Asked Questions. NeXT Software Archives @ Peak.org http://www.peak.org/next http://www.peak.org/openstep PEAK is the premier NeXTStep/OpenStep FTP site in North America. NeXT Software Archives @ Peak.org http://www.peak.org/next http://www.peak.org/openstep PEAK is the premier NeXTStep/OpenStep FTP site in North America. This is the World Wide Web interace to the FTP site. Apple Enterprise Software Group (formerly NeXT Computer, Inc.) http://www.next.com Here is where you'll find the NeXTanswers archive, with information on OpenStep installation, drivers and software patches. Apple Computer's 'Prelude to Rhapsody' Self Support Site http://devworld.apple.com/dev/prelude.html This site has been constructed to help you help yourself to learn as much as possible about the foundation for Rhapsody, today's OPENSTEP. The site provides an informal collection of pointers, references, and starting points for developers who are using the Prelude to Rhapsody bundle, distributed at this year's Worldwide Developer Conference. OpenStep/NEXTSTEP/Rhapsody Related Usenet Newsgroups ==================================================== COMP.SYS.NEXT.ADVOCACY This is the "why NEXTSTEP is better (or worse) than anything else in the known universe" forum. It was created specifically to divert lengthy flame wars from .misc. COMP.SYS.NEXT.ANNOUNCE Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. Messages posted to announce should NOT be posted or crossposted to any other comp.sys.next groups. COMP.SYS.NEXT.BUGS A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT-specific groups as well. COMP.SYS.NEXT.HARDWARE Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. COMP.SYS.NEXT.MARKETPLACE NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. COMP.SYS.NEXT.MISC For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! COMP.SYS.NEXT.PROGRAMMER Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. COMP.SYS.NEXT.SOFTWARE This is a place to talk about [third party] software products that run on NEXTSTEP systems. COMP.SYS.NEXT.SYSADMIN Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. ** RELATED NEWSGROUPS ** COMP.SOFT-SYS.NEXTSTEP Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. COMP.LANG.OBJECTIVE-C Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. COMP.OBJECT Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups. Getting the Newsgroups without getting News =========================================== Thanks to Michael Ross at antigone.com, the main NEXTSTEP groups are now available as a mailing list digest as well. next-nextstep next-advocacy next-announce next-bugs next-hardware next-marketplace next-misc next-programmer next-software next-sysadmin object lang-objective-c (For a full description, send mail to listserv@antigone.com).

While the IconKit works even under NT (hey...need a real browser for WinNT..you foun one :-).. there is a lot of things I discovered in the sources which definitly should be changed since we are now living under Openstep. This starts with method names, autorelease policies and ends with the IConKit using its own private way of "notifications", whcih was cool under 3.x but we now should use the standard mechanism. I would like to continue the work..but would like to donate it to the MiscKit (with Scott as the main author..sure) since we already dplicated some of his work and protocols...and now should fold both pieces together if he is willing to support this move.

I *think* I've got it set up correctly, but something is obviously wrong (it isn't working!): - The overall project is set to build a debug target. - There is a subproject in my main project for my loadable bundle. - It is set up as a "loadable bundle" in the project inspector. - The principal class is specified, and has the same name as the subproject. - There is also a nib file in the subproject. While the entire project builds with no errors or warnings, examining the loadable bundle in the workspace reveals no executable file matching the name in the property list (there is an executable, but it is the bundle name with _DEBUG appended). Stepping through the source in GDB has [NSBundle principalClass] returning an error (NSFileObjectImage... 5) I'm sure I'm missing some small but critical part of the setup, but multiple readings of the documentation have left me at an impass. ANY help that can be provided will be gratefully accepted! I love the environment in general, but these oversights and gotchas in the documentation are driving me nuts! Thanks in advance, Frank Alviani

Most likely you forgot to change the application class from NSApplication to your custom subclass in PB. When you start your program an instance of NSApplication will be created and it one does not respond to you custom methods.

I wonder if Apple bundles Interface-Builder and all the other Tools with their DR ? I have read two books on OpenStep and I am amazed, how powerful the tools are. I hope the premiere release (including development-tools) will be at an affordable price ($200-500), then I think Rhapsody can be a big success for Apple. I'm working in a technical profession (electrical engeneering), where Apple is not "existing" yet. I personally like the way Apple defined programming-interfaces. At my last job I had to create a program that interfaced a PC to a microcontrollerboard. I think thousand of programmers had to implement the same, but it is still horrible to programm the UART at lowest level. When I looked into "Inside Macintosh" I saw how smart it can be when there is a well defined programming-interface. I hope this will be continued with Rhapsody. For me it is MOST important, not to lose time implementing things, thousands of programers have do before. I hope Rhapsody will combine well defined programming interfaces and easy powerfull tools. Another problem to be solved is how to transfer information to developers. In the USA it might be affordable to download documentation, but here in Europe it is a problem. First at all telephone-fees are high and the connection speed is rather slow. (From Austria to the USA it is about 400-800 Bytes/sec, to Germany it is sometimes less than that) But there are some monthly Apple-CDROM-Magazines. I think Apple could distribute certain development-information through them. Apple forever!!

Yes, Rhapsody DR1 will be available to all members of Apple's developers programs (both the associate and partner levels) who sign a NDA (non-disclosure agreement). The Associate level is a mere $250 per year and you get several CD's of OS and experimental software over the year and some level of technical support. It's a good deal. Scott Johnson

You couldn't directly declare something to be complex data, but you could store it as two float samples per pixel. Read the TIFF spec rather than inferring its limitations from some piece of software. Most "TIFF" software I've seen barely manages all of the baseline-TIFF subset. Now, if you're looking for a format where all of the above is actually supported by the "average application", I'm afraid you're out of luck. Most apps wouldn't handle the above regardless of format. ftp.sgi.com:/graphics/tiff/ has the TIFF spec and a more-complete-than- the-average-implementation TIFF library. You should also look at scientifically-oriented data formats, like HDF and FITS. I don't know much about those, but they might be up to the task. regards, tom lane

Surprisingly enough, all this overhead is not necessary in my case. I tried and modified the example code you pointed me to to include my task, and the result is exactly the same as with my simple example code: writeRTFDTo: doesn't work (always writes the string "rtfd"), writeText: and writeRichText: works as they should (cf. my other post on the subject) Bye Uli -- _____________________________________________________________________ Uli Zappe E-Mail: uli@tallowcross.uni-frankfurt.de (NeXTMail,Mime,ASCII) PGP on request Lorscher Strasse 5 WWW: - D-60489 Frankfurt Fon: +49 (69) 9784 0007 Germany Fax: +49 (69) 9784 0042 staff member of NEXTTOYOU - the German NEXTSTEP/OPENSTEP magazine _____________________________________________________________________

Ooops! Overlooking on my side. Unfortunately, it doesn't change a thing (I wrote this NXRead(stream, buffer, 999) in my example code for clarification; actually, I had a look at stream's content in gdb). Nevertheless, I got one step further: actually, the buffer in the example code isn't empty, but contains the string "rtfd" (no matter what text is in the text object). So it turned out that it's a writeRTFDTo: problem; if I use writeText: or writeRichText:, everything works as it should. For clarification, once again the (modified) example code: ------------------------------------- #import <appkit/appkit.h> int main(int argc, char **argv) { id text; NXStream *stream; NXRect rect={ 0,0,1000,1000 }; char buffer[1000]; stream=NXOpenMemory(0,0,NX_READWRITE); text=[[Text alloc] initFrame: &rect text: "This is a test." alignment: NX_LEFTALIGNED]; /**** use one of the following three lines alternatively ****/ [text writeText: stream]; // DOES WORK [text writeRichText: stream]; // DOES WORK [text writeRTFDTo: stream]; // DOES NOT WORK (output is always // "rtfd") NXSeek(stream,0,NX_FROMSTART); NXRead(stream,buffer,999); printf("\n\nOutput:\n%s\n\n", buffer); exit (0); } ------------------------------------- So, what's the problem with this writeRTFDTo: method? Any special treatments necessary? Thanks for your help!

Message-ID: <5tg4la$j2h$2@concorde.ctp.com> Hi, as I already posted there is no documentation for the AppKit functions with OpenStep 4.x. Switching to the 3.3 docu is of little sue since the paramters have changed and even many functions have changed to 4.x. Initally we suspected that NeXT forgot to put the docu on the CD...but the "official" answer seems to be that they really forgot about creating that docu file completely. However...yesterday late at night I woke up and it suddenly appeared before my eyes. The OpenStep Specification !! So if you need a somehow useful function docu..grab the OpenStep spec. However...it is not 100% since at least one function which is included in the spec is misisng in Openstep 4.2 (NSRunLocalizedAlertPanel(...)) But its better then nothing...and better the the 3.x text sicne you don't have to guess the parameters and which functions survivde the move to OpenStep. Aloha Tomi

This may impeed debugging (using gdb) efforts if you are building programs using those libraries. If you need non-stripped libraries, you can build libg++ by hand from the original source. libf2c.a is used only for g77 builds, which is a little harder to build...

When you build your app for profiling (to check how much time in spent in various routines), these alternal libraries are linked in so that you can get accurate timing measurements in the NeXT-supplied methods. If you never build for profiling, they are safe to delete. In fact, a few years back when we mostly had 200MB NeXTstations, this is one of the ways we used to save space. One machine had profiling capability, the rest had more room for source and swap space. -- Gregory H.

I'm not sure that you've hit it since it usually manifests itself as a broken file with an rtfd extension. rtfd's should be folders. The solution is to load a real rtfd file (folder) into the text object, after that the stream operations work correctly. Sounds crazy, but it works. With an app this isn't too much of a problem since you can dump an rtfd file within the app wrapper and just load it. In your case with a UNIX tool it's probably a big deal. Jim

A comprehensive list is available on Stepwise. Stepwise OpenStep/Rhapsody Information Server http://www.stepwise.com Stepwise has been serving the OpenStep/NEXTSTEP community since March 1993. Some of the many resources on the site include: OpenStep Third Party Software guide, Developer Directory, Mailing List information, extensive listing of FTP and WWW sites related to OpenStep and NEXTSTEP, OpenStep related Frequently Asked Questions. NeXT Software Archives @ Peak.org http://www.peak.org/next http://www.peak.org/openstep PEAK is the premier NeXTStep/OpenStep FTP site in North America. NeXT Software Archives @ Peak.org http://www.peak.org/next http://www.peak.org/openstep PEAK is the premier NeXTStep/OpenStep FTP site in North America. This is the World Wide Web interace to the FTP site. Apple Enterprise Software Group (formerly NeXT Computer, Inc.) http://www.next.com Here is where you'll find the NeXTanswers archive, with information on OpenStep installation, drivers and software patches. Apple Computer's 'Prelude to Rhapsody' Self Support Site http://devworld.apple.com/dev/prelude.html This site has been constructed to help you help yourself to learn as much as possible about the foundation for Rhapsody, today's OPENSTEP. The site provides an informal collection of pointers, references, and starting points for developers who are using the Prelude to Rhapsody bundle, distributed at this year's Worldwide Developer Conference. OpenStep/NEXTSTEP/Rhapsody Related Usenet Newsgroups ==================================================== COMP.SYS.NEXT.ADVOCACY This is the "why NEXTSTEP is better (or worse) than anything else in the known universe" forum. It was created specifically to divert lengthy flame wars from .misc. COMP.SYS.NEXT.ANNOUNCE Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. Messages posted to announce should NOT be posted or crossposted to any other comp.sys.next groups. COMP.SYS.NEXT.BUGS A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT-specific groups as well. COMP.SYS.NEXT.HARDWARE Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. COMP.SYS.NEXT.MARKETPLACE NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. COMP.SYS.NEXT.MISC For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! COMP.SYS.NEXT.PROGRAMMER Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. COMP.SYS.NEXT.SOFTWARE This is a place to talk about [third party] software products that run on NEXTSTEP systems. COMP.SYS.NEXT.SYSADMIN Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. ** RELATED NEWSGROUPS ** COMP.SOFT-SYS.NEXTSTEP Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. COMP.LANG.OBJECTIVE-C Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. COMP.OBJECT Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups. Getting the Newsgroups without getting News =========================================== Thanks to Michael Ross at antigone.com, the main NEXTSTEP groups are now available as a mailing list digest as well. next-nextstep next-advocacy next-announce next-bugs next-hardware next-marketplace next-misc next-programmer next-software next-sysadmin object lang-objective-c (For a full description, send mail to listserv@antigone.com).

I've overridden mouseDown: and added a method handleMouseMoved:... - (void)mouseDown:(NSEvent *)theEvent { int mask = NSLeftMouseUpMask|NSLeftMouseDraggedMask; theEvent = [NSApp nextEventMatchingMask:mask untilDate:[NSDate distantFuture] inMode:NSEventTrackingRunLoopMode dequeue:YES]; if([theEvent type] == NSLeftMouseDragged) { [self handleMouseMoved:theEvent]; } } - (void)handleMouseMoved:(NSEvent *)event { NSPoint p; NSEvent *newEvent; int mask = NSLeftMouseUpMask|NSLeftMouseDraggedMask; NSPoint offsetPt = {0.0, 0.0}; NSPoint origPt = [self convertBaseToScreen:[event locationInWindow]]; NSPoint newPoint; offsetPt = [self convertBaseToScreen:offsetPt]; p = offsetPt; newEvent = [NSApp nextEventMatchingMask:mask untilDate:[NSDate distantFuture] inMode:NSEventTrackingRunLoopMode dequeue:YES]; origPt = [self convertBaseToScreen:[newEvent locationInWindow]]; while (newEvent && [newEvent type] != NSLeftMouseUp) { newPoint = [self convertBaseToScreen:[newEvent locationInWindow]]; p.x = newPoint.x + offsetPt.x - origPt.x; p.y = newPoint.y + offsetPt.y - origPt.y; [self setFrameOrigin:p]; offsetPt = p; origPt = newPoint; newEvent = [NSApp nextEventMatchingMask:mask untilDate:[NSDate distantFuture] inMode:NSEventTrackingRunLoopMode dequeue:YES]; } [self setFrameOrigin:p]; } The problem is, when dragging the window around it jumps around, oscillates a little bit, looks really bad. Not at all like dragging a window by the title bar. This code is basically Openstepified Fiend code. I don't understand why its not working... Does anyone out there have any ideas? My gut tells me that something is going on with the Openstep event queue that I don't know about....

Not at all like dragging a window by the title The problem is that your code receives events...and during handling that even changes to location of the window. Event coordinates are in window coordinats and get spooled. Now some of the evetns which alrady are in the queue do no longer match the real position after you have moved the window. Can you follow me ? I have attached my code which drags around the shelf window in my 4.x port of "TheShelf". It does pretty much the same like the stuff you want to do. It bascially is just a view which is used to drag the entire window. The magical line is: curLocation = [ourWindow mouseLocationOutsideOfEventStream]; While you should trace the events...you should not take the mouse location which has been stored in the event. Aloha Tomi @implementation TSShelfDragView - (BOOL)acceptsFirstMouse:(NSEvent *)theEvent { return YES; } - (void)mouseDown:(NSEvent *)theEvent { NSPoint mouseLocation, curLocation, offset; BOOL buttonDown; NSRect theFrame; id ourWindow; ourWindow = [self window]; theFrame = [ourWindow frame]; mouseLocation = [theEvent locationInWindow]; mouseLocation = [ourWindow convertBaseToScreen:mouseLocation]; offset.y = theFrame.origin.y - mouseLocation.y; theEvent = [ourWindow nextEventMatchingMask:NSLeftMouseDraggedMask|NSLeftMouseUpMask]; while( [theEvent type] != NSLeftMouseUp ) { curLocation = [ourWindow mouseLocationOutsideOfEventStream]; curLocation = [ourWindow convertBaseToScreen:curLocation]; theFrame.origin.y = curLocation.y + offset.y; // Here you should check if the mouse button is really still down...important since // otherwise we might get a drag.

MAagic !!! :-) This is actually one of the really cool featues of OpenStep. By default menu cells enable and disable themself automagically. The mechanism is described in the documentation. What it bascially comes down to is: "If a menu item finds a target which is willing to perform the specified action it is enabled...it there is no valid target it is disabled." The items are usually updated after every major event...so it nicely works even for tear off menues and such. Check the docu. Aloha Tomi

Given that you are using 4.1 there might be some other problems with the OpenPanel as well. Selecting directories had some really wierd effects as far as I rememerb and should be considered a bug (e.g. when dropping in a directory it was accepted right away as if you clicked the Ok button..really odd) Sorry if that doesn't really help.

Yeap...I know that. And as I said...to me it makes sense to have the "nil" in the "arrayWithObjects" method...but there is no way to put a "nil" into an NSArray...so the whole thing really seems a little odd given the "quote" which I provided below. So since I already got "bashed" for that one, here comes the orignial piece of docu that I was reffering to: >--- NSImage imageUnfilteredFileTypes + (NSArray *)imageUnfilteredFileTypes Returns a null-terminated array of strings representing those file types for which a registered NSImageRep exists. This list consists of all file types supported by registered subclasses of NSImageRep, and doesn't include those types that can be converted to supported file types through a user-installed filter service. The array returned by this method may be passed directly to the NSOpenPanel's runModalForTypes: method. See also: + imageFileTypes <----- See that "null-terminated" phrase!? This definitly seems like a docu-bug to me...but being burned by the OpenPanel of 4.1 I did not necessarily outrule the possibility of this being a problem in the original posters case. But as Georg propably already posted by now the original problem is more likely related to the "setTreatsFilePackagesAsDirectories" method. And here IMHO we have reached another "docu" problem since it is not properly documented what the default value/behavior of a freshly created "NSOpen/SavePanel" will be. "treatsFilePackagesAsDirectories" should say "Returns YES/NO? for a freshly created instance of NSSavePanel". Aloha Tomi

Date: 24 Aug 1997 18:15:28 GMT Organization: Cambridge Technology Partners, Inc. Message-ID: <5tpto0$aap$2@concorde.ctp.com> Hi, while working on my documentation tool for the MiscKit I ran into this somewhat strange problem (which I consider a "bug" in NeXTs text system) Originally my code looked similar to this one (useless stuff removed for the posting): - (BOOL)_openFile:(NSString *)filename { id newText; id newStorage; id ourLayoutManager = [[textView textContainer] layoutManager]; newText = [NSString stringWithContentsOfFile:filename]; newStorage = [[NSTextStorage alloc] initWithString:newText]; // Do I have to unregister the "reused" layoutManager ?? It should // take care of necessary cleanups when getting reassigned to a // new storage..shouldn't it ? [newStorage addLayoutManager:ourLayoutManager]; } Please notic the "initWithString:" which is valid initMethod for a textStorage since after the init the storage really shows the correct "string" value when you ask for it. However....This simply crashed on me once the NSTextView had to redisplay itself for the first time. The stack showed something deep inside the NSLayoutManagers internals (NSPrivate) category: #0 0x0 in ?? () #1 0x601362e in -[NSTypesetter layoutGlyphsInLayoutManager:startingAtGlyphIndex:maxNumberOfLineFragments:nextGlyphIn dex:] () #2 0x601b046 in -[NSLayoutManager(NSPrivate) _fillLayoutHoleAtIndex:desiredNumberOfLines:] () #3 0x6202bfe in _NSFastFillAllLayoutHolesUpToGlyphIndex () #4 0x604d289 in -[NSLayoutManager(NSPrivate) _firstPassGlyphRangeForBoundingRect:inTextContainer:okToFillHoles:] () #5 0x604d5df in -[NSLayoutManager(NSPrivate) _glyphRangeForBoundingRect:inTextContainer:fast:okToFillHoles:] () #6 0x60c8dfc in -[NSLayoutManager glyphRangeForBoundingRect:inTextContainer:] () #7 0x60346f6 in -[NSTextView drawRect:] () #....... Looking at all the example sources I found, that in some places a different way of "initializing" the NSTextStorage is used. So I tried it like that: - (BOOL)_openFile:(NSString *)filename { id newText; id newStorage; id ourLayoutManager = [[textView textContainer] layoutManager]; newText = [NSString stringWithContentsOfFile:filename]; newStorage = [[NSTextStorage alloc] init]; [newStorage addLayoutManager:ourLayoutManager]; [newStorage beginEditing]; [[newStorage mutableString] setString:newText]; [newStorage endEditing]; } Notice that I now create an empty text storage and after assigning it to the layout manager I set the string value of the textStorage. This magically works. Did I miss something or is this really a bug like I suspect ? Aloha Tomi

While the latter is documented, I couldn't find any information about the former. The same goes for a lot of other NEXTSTEP libs (e.g. libNeXT_p.a <> libNeXT_s.a). The _p.a version is always much bigger in size than the corresponding _s.a. The _p versions are profiling versions (compiled with -p or -pg or whatever the flag is). They're also static rather than shared, which explains more of the size difference. When you build with "make profile", I think you get the shared libraries by default. So you only get profiling info for your own code. If you arrange to link against the profiling libraries instead (I don't remember how I did it, probably Makefile.* hacking), you get profiling info for all of the system functions, too. This makes your profiling output _significantly_ larger, and isn't helpful all that often. Interesting, though.

Here's the actual code where I'm trying to select applications and not files: - (void)addApplication:(id)sender { int result, i; NSOpenPanel *oPanel = [NSOpenPanel openPanel]; id applications = [currentLocation objectForKey:LOGON_APPLICATIONSKEY]; id enabled = [currentLocation objectForKey:LOGON_APPENABLEDKEY]; NSArray *filenames; if(!applications) { applications = [NSMutableArray array]; [currentLocation setObject:applications forKey:LOGON_APPLICATIONSKEY]; } if(!enabled) { enabled = [NSMutableArray array]; [currentLocation setObject:enabled forKey:LOGON_APPENABLEDKEY]; } [oPanel setAllowsMultipleSelection:YES]; [oPanel setTitle:@"Launch Apps..."]; [oPanel setCanChooseDirectories:YES]; // have tried both YES and NO [oPanel setTreatsFilePackagesAsDirectories:YES]; // Have tried both YES and NO if([oPanel treatsFilePackagesAsDirectories] == YES) fprintf(stderr, "treats packages as directories\n"); else fprintf(stderr, "doesn't reat packages as a directory.\n"); result = [oPanel runModalForDirectory:NSHomeDirectory() file:nil types:nil]; if (result == NSOKButton) { filenames = [oPanel filenames]; for(i=0; i<[filenames count]; i++) { NSDictionary *fatr = [[NSFileManager defaultManager] fileAttributesAtPath:[filenames objectAtIndex:i] traverseLink:YES]; NSLog(@"Adding file '%@' with permissions:%@", [filenames objectAtIndex:i], [[fatr objectForKey:NSFilePosixPermissions] stringValue]); if([[NSFileManager defaultManager] isExecutableFileAtPath:[filenames objectAtIndex:i]]) { [applications addObject:[filenames objectAtIndex:i]]; [enabled addObject:@"Y"]; } else { NSLog(@"User %@ does not have execute permission for '%@'!", NSUserName(), [filenames objectAtIndex:i]); } } [launchTableView reloadData]; } } What I hope to be able to do is allow the user to select a bunch of applications that will then be launched later by my app. Right now, the open panel doesn't display applications as single files, so you can't select them. Even specifying [oPanel setCanChooseDirectories:YES] doesn't allow the user to actually select a directory by clicking on it in the panel. You can type in the name of the application but this isn't good enough for me. Have any suggestions? How can I choose applications in an open panel? BTW, these applications are in LocalApps... -- |-------------------------------------------------------------------------| | Mark Trombino | J A M S o f t | | mtrombin@ix.netcom.com | Audio DSP Tools for Openstep & Rhapsody | |-------------------------------------------------------------------------|

However, what does? This is mentioned nowhere. I have 2 questions in this regard: 1. It's easy to locate NEXTSTEP's WindowServer. However, to my understanding it works only in connection with the GUI. Is this wrong, or what process is responsible for keyboard input and screen output during the boot process or in single user mode? 2. I couldn't find any process responsible for the local filesystem (I found nfsd etc., of course). What is it? Thanks for any insight!

One last suggestion. Your code has varaibles named ImageView, ScrollView, etc. This is pretty bad form since by convention, Objective-C classes are capitalized that way.

In my experience, PSsetinstance(TRUE) == [myWindow cacheImageInRect:cacheRect] PSnewinstance() == [myWindow restoreCachedImage], [myWindow flushWindow] PSsetinstance(FALSE) == [myWindow restoreCachedImage], [myWindow flushWindow], [myWindow discardCachedImage] The quickest way to set up the cacheRect is to get the window's frame, then set the origin to (0,0). Of course, if you know exactly which part of the window will be overdrawn (in its own coordinate space) you can specify something smaller. You don't need to convert the PSnewinstance() that typically follows PSsetinstance(TRUE), so that's one line of code that can be removed. In my example above, the three methods shown assume that you call PSsetinstance(FALSE) at the end of a modal loop of some kind where PSsetinstance(TRUE) was called at the top. To conserve memory, it restores the background one final time, then frees the cached image. One final caveat -- don't tell the entire NSWindow to display in the middle of your instance-drawing loop, or you will lose the cacheRect. The assumption here is that you want to retain the background and draw over it without changing the contents as part of the instance session. -- Gregory H.

The message needs to say [oPanel setTreatsFilePackagesAsDirectories:NO]; not YES ! I just tried the following code and it works just fine (ok..I jsut included the interesting lines): NSArray * files; NSArray * acceptedFileTypes = [NSArray arrayWithObject:@"app"]; NSOpenPanel * openPanel = [NSOpenPanel openPanel]; int numberOfFiles; [openPanel setAllowsMultipleSelection:YES]; [openPanel setTreatsFilePackagesAsDirectories:NO]; [openPanel setTitle:@"Open AppWrapper"]; if( [openPanel runModalForDirectory:[[NSUserDefaults standardUserDefaults] objectForKey:@"LastOpenDirectory"] file:nil types:acceptedFileTypes] ) ....etc....etc...

I know that 4.0 and 4.1 had a real bug when the panel was running for directories adn you used drag&drop from the Workspace to drop in some root location at which to continue continue the selection...the open panel would immediatly perform an "Ok" after the drop. I did not cehck this on 4.2 yet...maybe this "feature" is still there. So be warned. But as far as working with file-wrappers is concerned everything seem just fine to me. Aloha tomi

The first method saves away a part of the window's image. Typically after this step, some temporary drawing is done. The second method restores the previously saved image, undoing any drawing that has happened since it was saved. The third method releases the memory used to hold the saved image. - (void)cacheImageInRect:(NSRect)aRect; - (void)restoreCachedImage; - (void)discardCachedImage; And from the OpenStep 4.1 NSWindow documentation: Finally, to support transitory drawing by NSViews, NSWindow declares methods that temporarily cache a portion of its raster image so that it can be restored later. This feature is useful for situations where highly dynamic drawing must be done over the otherwise static image of the window. For example, in a drawing program where the user drags lines and other shapes directly onto a canvas, it's more efficient to restore the window's cached image and draw anew over that than to have all of the view objects send PostScript instructions to the Window Server. For more information, see ƒTransitory Drawing in the NSView class specification, and the individual method descriptions of cacheImageInRect:, restoreCachedImage, and discardCachedImage in this class specification. -- Eric Norum eric@skatter.usask.ca Saskatchewan Accelerator Laboratory Phone: (306) 966-6308 University of Saskatchewan FAX: (306) 966-6058 Saskatoon, Canada.

Apple has not announced the terms of any agreements with Adobe for DPS runtime on Windows, but it seems reasonable to assume they would not have announced free NT runtime bundling without one. I would bet they negotiated a blanket license, since they won't have any control over how (or how frequently) individual software developers deploy the runtime. At this point, my expectation as a developer is that I will be able to incorporate the necessary components of the runtime with any Yellow Box software I bring to market, such that everything installs at once. > Dare I meantion GX in this context? ;-) There would only be surprise if you _didn't_. 8^) -- Gregory H.

There is no difference between [NSArray arrayWithObject:@"LogOn"] and [NSArray arrayWithObjects:@"LogOn", nil] except that the second takes a variable number of arguments and because of this the methods needs a marker (which is nil) to now where the end is.

I was able to read both using OmniPDF, but the fonts were all wrong and the graphical font used for check boxes printed as a large mirror-image "P". It's odd to me that Adobe's PDF reader under NT was able to display the documents perfectly despite the use of Apple fonts. No font substitution was reported. But when I tried to print these documents from NT using my NeXT printer, they printed just like OmniPDF displayed them - with incorrect fonts. So much for a portable document format.

Hmmm. Hopefully I won't botch the explanation too badly. 'self' is an implicit variable within an objective C object which refers to itself. If you are familiar with C++, it is essentially the same as C++'s 'this' variable. My methods pass 'self' (actually I do most of my work in C++, so I use 'this') to other objects or functions when they want to register themselves with someone else (e.g., to provide a callback function). 'super' can be used to call a method of a parent class. For example, a particular class my support a method called pushButton() that does almost everything you want, but not quite. You can create a subclass and implement your own pushButton() method. Your version of the pushButton() method may only do one or two simple things (but which are important to you), and then call the original version of pushButton() in the parent class. This is done by using the 'super' reference. In C++ it is a little uglier, but by and large the same things can be done. (Did I screw it up? My ObjC is a little rusty) Todd Heberlein

There IS magic ;-) Before a filename is displayed your application gets the chance to look at the name and decided if its worth displaing or not. So if you want to do that you tell the panel to accept every file (not filetypes) and then add the code to get the files attributes and see if it is an executable or has the .app extension. Acutally there already is a isExecutableFileAtPath method in the NSFileManager class. You just would have to check if it returns YES for the app wrappers themself. So maybe it all comes down to one additional line of code in one additional delegation method. Sounds easy to me. ;-) Aloha Tomi

Consider this: A company (or institution) uses a data base to store information on its staff and the work they do (i.e. documentation). The company may want to make all (or some) of this avaialble to the network. They furthermore want to let all the world know who works there and what they do. So why not use the database they already have, add a few fields so that the employed can add personal information and then interface this to the web? The same applies to any documentaition or other information. The pages won't change *every* time they are accessed. Infact, they will rarely change. The benefit of this scheme is that the comany will have "uniformed" pages (all pages are presented the same way and have the same functionality) and very little administrative overhead. Now, of course, this compatny want's to have its pages indexed so that web surfers all around the world can find them. In this case it would be very usefull if we had a protocol that would let the automated indexing machines negotiate with the company's server and ask for an existing index rather than scan all pages. In this way, the company could determine which indexes are to be used themselves and the robot indexer can complete its job very quickly. -Robert -- Institut fuer Informatik tel +41 (0)61 321 99 67 Universitaet Basel fax. +41 (0)61 321 99 15 Robert Frank Mittlere Strasse 142 rfc822: frank@ifi.unibas.ch (NeXT,MIME mail ok) CH-4056 Basel X400: S=frank;OU=ifi;O=unibas;P=switch;A=arcom;C=ch Switzerland

Well, not really that easy. And still beside the point. The biggest problem with WOF apps & robots is that the dynamic URLs generated don't clue the robot in to the fact that it has gone into a recursive loop. The canonical example of this is the TimeOff(html) example. Put that where a robot can find it, and then sit back and watch the fun as AltaVista brings your server to it's knees. The second biggest problem is that the session id that's in most dynamic WOF URLs is just going to present some user with a "Sorry, your session has timed out" page (if they're that lucky, and you've implemented a nice pretty one). Not a great ad for your company or it's cool products/services. All that being said, there's no restriction at all in putting whatever you want into the entry point to your WOF apps. This includes all the interesting keywords as to the exciting content therein. This also saves the user of said indexer the pain of seeing gajillions of your dynamic pages showing up as search results, when it only makes sense for him to enter through the one front door anyway.

To sum up: Adding instance variables to a class breaks code that depends on that class. (The "broken" code would need to be recompiled.) Now, I'd always thought it was silly that instance variables were declared in the @interface, but I didn't figure that meant that changing them would actually break the class. It seems to me that, since all Objective-C objects are dynamically allocated, this would be fixable. Maybe it wouldn't be simple, but it would be fixable.

To be precise, adding ivars breaks classes that DESCEND FROM that class. There should not be any impact on non-descendent classes that happen to use functionality of the modified class. That's because the values of ObjC ivars are typically accessed through method calls, EXCEPT in the class where the ivars are declared, and sometimes descendent classes. In OPENSTEP, NeXT/Apple officially frowns on descendent classes using direct access to ivars. For example, it used to be possible in NEXTSTEP subclasses of NSView to say [window doSomething]. In OPENSTEP, you say [[self window] doSomething], which provides a layer of insulation from this problem. > Now, I'd always thought it was silly that instance variables were > declared in the @interface, but I didn't figure that meant that > changing them would actually break the class. The problem is that ivars are stored as a nest of structs. The compiler then resolves direct access to ivars as an offset into the structs. If you then go back and add an ivar at the end of a class somewhere in the middle of this nested hierarchy, the new ivar occupies the same physical space as the first ivar of previously-compiled immediate subclasses. > It seems to me that, since all Objective-C objects are dynamically > allocated, this would be fixable.

My bigger complaint is the ongoing lack of class variables.

This is mentioned nowhere. There is no process responsible for local file system I/O. The biod and nfsd processes are user space processes which implement NFS. NFS was taken out of the kernel many years ago both for efficiency and simplicity since most of its work is different (and slower) than traditional file system I/O. The local I/O subsystem is part of the underlying Unix layer (it must be in order to integrate cleanly and efficiently with the VM subsystem). Every thing having to do with file system IO is handled first by a generic layer of file system and VM structures which then eventually involve calling device specific driver routines to submit block requests to a drive. A view from 20,000 feet shows, that all file system I/O is first handled by the vfs+vinode layer ('v'irtual file system and 'v'irtual inode). This layer isolates the system calls from all device specific and file system specific knowledge. The vinode layer is supported by file system specific layers which can either be built into the kernel or dynamically loaded when a new type of filesystem is to be supported. beneath the vinode layer are also subsystems for performing other device specific I/O routines for ttys/ptys and other types of devices. These intermediate layers implement generic file system operations which turn file system requests into lower level, page level (block oriented) requests. Finally, device specific drivers (like SCSI drivers) are responsible for taking sorted lists of block I/O requests, and transferring data between blocks on a disk drive and buffers in memory. Sorry if I made this sound complicated, it's been a while since I've dealt with this. Although there are a number of different layers to deal with, the code is well designed, with clean interfaces. It ensures, that all I/O, whether based on a direct system call, or caused by VM paging activity is serviced by the same routines in order to maximize the effectiveness and minimize the cost of buffering. It is actually quite a beautiful way of doing things. If you are interested in reading up on how this works, I recommend either of the 'Devil' books. "The Design and Implementation of the 4.4 BSD Operating System", is the most recent devil book in the pink cover. The older one is still useful, but since it describes the 4.3 BSD Unix, is somewhat dated. These are the BSD Unix bibles, the definitive descriptions of the Unix design. -- ___ ___ | James E.

Hm, this sounds very plausible to me. But since VM *is* implemented in the Mach kernel which is supposed to be the most basic layer, this seems to imply that the basic (local) file system I/O is *also* handled by the kernel, or am I totally mistaken at this point? It's what I thought, actually, but it contradicts the documentation that says that NeXTs Mach does *not* handle file system I/O.

That's correct, in the sense that all classes that inherit from the affected class must be recompiled. Code that merely uses the class (or its subclasses) does _not_ have to be recompiled (as it does in, for instance, C++) -- unless it breaks encapsulation and references the class's instance variables directly (which considered a bad practice in general anyway:-) Just adding new methods does _not_ break the class (as it does in, for instance, C++). > Now, I'd always thought it was silly that instance variables were declared > in the @interface, but I didn't figure that meant that changing them would > actually break the class. > > It seems to me that, since all Objective-C objects are dynamically > allocated, this would be fixable. Maybe it wouldn't be simple, but it would > be fixable. Well, my best guess is this is a tradeoff between flexibility and allocation / instance variable access efficiency. In the current scheme, an instance can be allocated as a single blob of memory. Also, ivars in instances of classes and subclasses alike can be accessed by a single pointer+fixed-offset dereference, which is about as efficient as you get.

But in reality, you can survive with static variable declared in the implementation file. And if this is not puristic enough, you always can write a relatively simple category to the NSObject that sticks them in a dictionary and you access them with key-value coding...

Yes: the solution is to check the request headers to determine that the browser is in fact a robot, and generate a special "robot friendly" version of everything on your site. For example, by not maintaining state. Subsequent requests to those URLs that the robot saves would pop you into an appropriate location, but with human-friendly content. As I see it, and I'm *really* extemporising now, the challenges here represent: 1) where does your site cut off robots: you want them to see content, but not, say, the order pages. 2) maintaining what is essentially a separate "user experience" for robots. Which is to say, programming your app for two completely different "users". The alternative here is to program one solution for both, but really, you want the live users to have all the fun, and so your primary focus is and must always be them. And robots don't give a stuff about those graphics. ;-) >2- A hack that would try to work *now* with existing webots. > >Question: can WOF and associated web servers construct faked static >URLs with contents from dynamic pages? > >When a webot visits our site, we could present it a page > >http://www.sharperimage.com/faked_static_pages/TurboTieRack.html > >which would a) contain relevant text to be indexed and b) act as a >valid entry point to our WO App. > >Is this presently possible? Yes, this is the "second" user experience. But you don't need WOF for this, just EOF and a single pseudo-catalogue page template. Then generate a static page for each item (or logical grouping thereof) in your catalogue, with a link/refresh to the real WOF app. This is SO MUCH against the very philosophy of WOF that I can't imagine doing it, and I feel guilty even thinking of it. :-) Your point about the tie-rack is definitely valid, but the question is (note how I deftly change focus :-), how many people are going to type that kind of query, and is Sharper Image or any other client going to ever make enough money off these people to recoup the costs of what is a significant programming challenge? IMHO, it's just as easy, well, vastly easier, to bung all these keywords into the home page (or a couple of pages grouped by subject) where a robot will find them but ordinary human browsers never do. It should be a simple EOF job to run a periodic query over your database, extract the pithy keywords, and pop them into page(s) while you sleep. (just as an aside: view the source of a bunch of pages, and see how many have "sex" hidden in them :-) It would be a cool thing for a third-party to develop a plug-in framework for WOF, but I don't think it's worth it to Sharper Image or anyone else to create a hacky, home-rolled solution (just to have the WOF API change out from under them when the next major release ships. Don't laugh: look how much EOF changed from 1.x to 2.0!). Of course there are other, EVIL, hacks, that I'm sure you'll be hearing about from other people I know. ;-) Dave -------------------------------------------------------------------------- /\/\ David A.

It is possible that the entry WOF app understands that not a human but a robot is bugging it. In this case it produces a gigantic index containing hrefs of strange form.

It's what I thought, actually, but it contradicts the documentation that says that NeXTs Mach does *not* handle file system I/O. The Mach portion does not handle such things. The BSD kernel does. Of course, that's part of the actual mach kernel binary (sdmach or mach_kernel or whatever it is) under NeXTSTEP. A performance choice.

What happened IMO to Objective-C is the opposite of what you say. Originally the heritage of Objective-C was Smalltalk, not C ... What gradually happened, was an increasing influence of C on Objective-C, and the ST influence is becoming less obvious. Objective-C started to look more and more like C, and also started to contain more language extensions that you don't find in ST (that is, went to live a life on its own). To illustrate this, here is a snippet of code out of Brad Cox 1986' Producer (ST to OC converter) : = Block:Node CATEGORIES() { id blockVariables, statements; } + statements:aStatementList { return [[self new] statements:aStatementList]; } - variables:aVarList { if (!aVarList || [aVarList isEmpty]) return self; [aVarList addContentsTo:blockVariables = [Set new]]; [symbolScope add:blockVariables]; return self; } So this was the programming style anno '86. Far from "C heritage". What gradually happened, in part because of the hybrid nature of O-C, in part just because NeXT did this, and people followed the example blindly because of the marketing might of a rich company, is that programmers started to use more and more C elements. The replacement by NeXT of +new by +alloc, -init is a good example. Something like +allocFromZone: doesn't make sense in ST, since it is so tightly linked to C memory allocation issues (the pointer zone where you want the memory for your object allocated). What's happening here is that a method (+new) which doesn't talk at all about allocation, is replaced by something which is closer to the C model. The increasing use of C types in method declarations (instead of Objects) is another example. So Objective-C starts to look more like C and its Smalltalk heritage is sort of getting to the background. It would be quite refreshing for O-C to renew the links with languages like Smalltalk, or Self etc. and model again the programming style after those languages (as it was originally the idea to take ST-80 code and use it in C). I see the work that I'm doing on Blocks (snippets of code that are dealt with like Objects) in this context.

This is certainly not a `C element'; it solves the following problem: use of `new' depends upon reassigning self in a class method to be the address of an instance, and then acting as an instance _in that class method_. Such behaviour is insane, at least in my opinion, and alloc+init solve it. Something like +allocFromZone: doesn't make sense in ST, since it is so tightly linked to C memory allocation issues (the pointer zone where you want the memory for your object allocated). Zone allocation is related to VM issues, which affect every system which has VM, which includes every desktop system currently available. The idea is to group related objects with similar lifetime and activity (as a function of elapsed time) into the same memory `regions' to increase locality of reference. It has nothing to do with C. If a zone were represented as an object, the same concept would be equally useful, also in Smalltalk. The increasing use of C types in method declarations (instead of Objects) is another example. Using the basic C types such as int is a good idea since it is a lot faster than using objects, and most of the time they suffice since the objects wouldn't be used in any way different than the C types are used now. Using structs and unions obviously is an error and the use by NeXT of NSPoint, NSRect and NSSize is something I don't fancy, not even when the argument in favour is `efficiency'. (In C++, the same argument can be held accountable for many errors in the language.) (as it was originally the idea to take ST-80 code and use it in C). How? Syntactically identical? --Tiggr

Download our catalog from our Internet Website http://www.activenetwork.com HARDWARE TRENDS BREAKING SPEED LIMITS Early benchmark tests on a prototype 300-MHz system are promising This fall will mark the arrival of a class of machines based on Intel's 300-MHz Pentium II processors, and early benchmark tests on some of the prototypes show healthy-- if not astounding-- performance gains over previous-generation Pentium systems. At NEC's invitation, PC Magazine had the chance to run tests on the company's new 300-MHz PowerMate Professional, due to ship in September. Although the configuration we tested was preliminary, the machine posted some impressive numbers. On the ZD High-End Winstone 97 test, the PowerMate earned a score of 34.8. This test runs a set of applications that heavily exercise the CPU and graphics subsystem, but purely CPU-intensive tests were really where the machine did well. On our CPUMark32 test, it posted a score of 735; on CPUMark 16, the system earned a speedy score of 556. To put these results in perspective, note that our recent test of the 266-MHz Dell Dimension XPS H266, resulted in a CPUMark32 score of 719, as opposed to the NEC system's 735, and the Dimension was the fastest by a wide margin in a group of systems based on Intel's 266-MHz Pentium II processor. The Dimension did, however, post a slightly higher score on High-End Winstone 97 than the PowerMate--36 rather than 34.8-- thanks to its advanced graphics subsystem. Most of the other 266-MHz system in our roundup posted speed scores well behind the PowerMates. Again, the configuration is still preliminary. More Adrenaline This Fall In the fall, Intel plans to ship its 440LX chip set, which supports Accelerated Graphics Port (AGP) technology and will work with a new dedicated bus for graphics. The speeds posted by 300-MHz machines-- especially on graphics tasks--are likely to benefit greatly from these technologies, as bus bottlenecks currently undermine high-speed processors. Although tests show 300-MHz system to be marginally faster than 266-MHz Pentium units, the new chip set should provide a healthy shot of adrenaline. Many customers will want to time their purchases of 300-MHz machines to correspond with the chip set's arrival, but NEC's $4000 PowerMate is likely to ship in advance of the chip set. Also note that Intel has been speeding up price drops on its high-end chips in recent years, and 300-MHz systems should be substantially cheaper than $4000 by 1998. They promise to be an important step for Intel as it faces increased competition in high-end chips from AMD and Cyrix. ***************** MEMORY************************** HIGHEST QUALITY.

The syntax is rather inspired on the syntax for compound statements, like in : [[anObject isOrange] ifTrue: { [citrus add:anObject]; } ]; where the stuff inside {} is a Block.

As long as there is no Rhapsody DR1 shipping it might be hard to say which would be the cleanes way to integrate the device. Rhapsody is supposed to come with a new "driverKit" called "IOKit" or that like. And there will be QuickTime support which nobody has seen yet as far as the OO wrappers are concerned. (QT in DR1 ?..not really announced officially..so it might be DR2) But you might get started with OpenStep anyway and later plug in the part which delivers the real data... but if its just displaying the Images this is a "NIB-ware" 5 minute drag&drop app. Aloha Tomi

I am not aware of a general way to define 'hardware interface components', every application seems to do it itself (well, on NS3.3 you could build a 'service'... I do not know if this still works on OpenStep/Rhapsody). Writing user level drivers for a given application is not so hard, for Network, SCSI and for serial communication, given effort, time and sufficient documentation (some companies do not even give you the time of the day when you ask them about this and unfortunately all internals are hidden in their binary libraries... go figure) -- * Frank M.

You have to do this from the command line. the .tar part indicates it's a tar (tape archive) file (/bin/tar -xf file.tar, in the location you want it expanded). The GUI automatically has the ability to do do this. If you're going to try to do it from the command line, I'd recommend reading both man pages ("man tar" and "man gzip") to be sure you're using the right arguments, etc. The various archives also have "Openner.app", which is a GUI front end for things like gzip, gnutar, etc. It's a useful tool. -- John "kzin" Rudd jrudd@cygnus.com http://www.cygnus.com/~jrudd =========Intel: Putting the backward in backward compatible.============ Thought for the day: According to the supreme court, proof of innocence isn't enough to avoid execution if you've exhausted your appeals.

Let me put that in a different way. What happened IMO to Objective-C is the opposite of what you say. Originally the heritage of Objective-C was Smalltalk, not C ... What gradually happened, was an increasing influence of C on Objective-C, and the ST influence is becoming less obvious. <...> So Objective-C starts to look more like C and its Smalltalk heritage is sort of getting to the background. It would be quite refreshing for O-C to renew the links with languages like Smalltalk, or Self etc. and model again the programming style after those languages (as it was originally the idea to take ST-80 code and use it in C). Though I'm impressed by what David has done with the portable compiler (I'm still working on my colleagues to switch over from StepStone, sigh), I'm not sure I agree with this last sentiment. I can understand why Objective-C has been migrating towards C - when it comes right down to it, NeXT is more interested in a language which has C's positives (speed, fine control) with sugar to coat some of the negatives. As it currently stands, Objective-C provides tastier sugar than C++. That said, in this day and age, with the fast machines we have, and the problems those machines have (CPU outrunning the main memory, for one), I think it would be much more appropriate to go with Smalltalk or Self, rather than a bastard child of those with C. Of course, this has the market/mind share problem - nobody programs Smalltalk, so nobody wants to. I guess my take on this, going by the popularity of C++ and Java, and my experiences with some of the people most taken by them, is that "everybody" (as opposed to "nobody") is not very knowledgable in object-oriented design, anyhow. If "everybody" were using Objective-C, they'd be using it in _spite_ of the Smalltalk influences, not because of them.

Message-ID: <EXMckvKmrW$b@cc.usu.edu> From: edx@cc.usu.edu Date: 28 Aug 97 22:57:14 MDT Distribution: world MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii I'm in the process of converting several apps from NextStep to OpenStep. It would appear that the Storage Class has disappeared from the environment. Is there a way to coax any FoundationKit classes into performing in a similar fashion? I'd just like a class which will manage a collection of structures, like the Storage class used to let me. Darn it, this can be frustrating - NeXT just seems to love to pull the rug out from under you. What is the point of having a Foundation library if you can't depend on the classes being there from one release to the next? TIA edx@cc.usu.edu

Date: 29 Aug 1997 18:42:35 GMT Distribution: world Message-ID: <5u756r$1t1e@fidoii.cc.Lehigh.EDU> Hi all, I'm writing a WebObjects application (in WebScript, not Objective-C), for which I need to implement a substring search facility. Users will need to hunt for substrings in large text files. For this purpose I thought I could use rangeOfString:. But though WebScript is supposed to support Foundation class methods, this doesn't seem to work. In my test component, the user's search string is called "searchString," and the data to be searched is called searchData. When the searchString is entered and the submit method invoked with the statement searchRange = [searchData rangeOfString:searchString] I get this: Exception while executing method submit: Exception while executing statement : searchRange = [searchData rangeOfString:searchString] Exception while evaluating WebScript expression [searchData rangeOfString:searchString]: Result can't be coerced to type '{?=II}' I'd be the first to admit my relative ignorance on the issue of ObjC-WebScript compatibilities, but if anyone can give me a clue, I'd be infinitely grateful.

DECLARED IN Foundation/NSRange.h SYNOPSIS typedef struct _NSRange { unsigned int location; unsigned int length; } NSRange You may notice that this is a C struct, not an Object. Although WebScript "is supposed to support Foundation class methods" it *only* deals with Objects, not C variables. Unfortunately the side effect is a significant loss of functionality, particularly in this case. Best wishes, mmalc. --

ST is garbage-collected by default, so you don't have to deal with -free / -dealloc either. Objective C, by default, isn't garbage collected, so you're forced to deal with allocation/deallocation issues whether you like it or not. Cheap shot aside, +alloc -init gives you, as a programmer, the choice to either pay attention to locality-of-reference issues or just ignore it. +new does not give you that choice. Addmittedly [Foo new] is 9 whole characters shorter than [[Foo alloc] init]. (whoops I'm doing it again...}->) > The increasing use of C types in method declarations (instead of > Objects) is another example. I'm assuming you refer to the increasing use of explicitly typed objects like (Window *) instead of generic (id) in later versions of NeXTSTEP, and OpenStep APIs, and not about C types like int or structs. (In fact, in OpenStep a couple of entities like events, DPS contexts that were structs in NeXTSTEP are now first-class objects. OTOH things like point, size, rect are still structs -- I don't like this much either. I can understand why NeXT initially chose to use structs in the first place, in light of the hardware it had to run on at the time. With OpenStep they had a chance to cleanup the APIs, and in some ways they weren't ruthless enough...) Another Good Thing IMO. ObjC is a compiled language, like it or not, and as long as I have to go to the compile/link/crash/fix cycle I'd like to get as much support from the compiler as I can get to catch my mistakes. My philosophy: if a method takes an (id) argument, it better be prepared to do something meaningful with it (and no, -doesNotRecognize is not meaningful in my book.), otherwise, by all means, declare it with an explicit, meaningful, type. But to each his own. If you're happy using wholly-untyped APIs, be my guest. Just don't expect me to feel comfortable with them. > So Objective-C starts to look more like C and its Smalltalk heritage > is sort of getting to the background. As far as the transition from NeXTSTEP to OPENSTEP is concerned, I think you're quite mistaken. As it now defines a standard foundation layer with string, array, dictionary etc. classes, in my experience most OPENSTEP code actually uses much less low-level C-style stuff like (char *) string futzing than in NeXTSTEP. > It would be quite refreshing for O-C to renew the links with languages > like Smalltalk, or Self etc. and model again the programming style > after those languages (as it was originally the idea to take ST-80 > code and use it in C). > > I see the work that I'm doing on Blocks (snippets of code that are > dealt with like Objects) in this context. Blocks are quite cool, I agree. Does it work, like in SmallTalk's do:, on each object in a collection of objects? (Forgive my ignorance, I haven't had a chance to look at POC yet.) BTW. do you have plans to support protocols in your Portable Object Compiler in the near future? Does it support categories? (the ObjC FAQ doesn't tell...)

It looks like something corrupted the PostScript stream such that one part of a binary sequence wound up being incomplete, and another part got misinterpreted as a huge array (which then hit the size limit for the interpreter). I suggest doing two things. Run the app under the debugger, and turn on PS tracing. To do this, once your app is running, break, and enter the gdb macro 'showps' (defined in /usr/lib/.gdbinit on 3.X systems). You could have something inserting postscript code at an inappropriate point, or a memory smasher that is corrupting the postscript stream buffer.

This is all correct, but... As long as the subclasses use accessor methods for all variable references, there should be no need to recompile even subclasses.
