Date: Sun 05-Feb-1989 01:56:56 From: Unknown Subject: More Questions OK, after bouncing the cube around, I've got a few more questions about the NeXT OS and Jot. 1) when I delete my mail, I still get .vox and Active.mbox files left around. Are these cleaned up by the 'destroy deleted files' option? I tried it and it didn't but I didn't try real hard. (rm is easier :-) 2) If I'm logged into another Unix machine and rlogin over to our cube, when I exit the rlogin session, the other machines login session hangs. It appears that rlogind doesn't really quit and clean itself up when it gets terminated. This results in having to go in and manually kill the normal login session on the (now) hung machine. The cube also doesn't clean up it's wtmp file, so a who shows that all these dead rlogins are still on the machine. Anybody know why the rlogin's hang? 3) Is it possible to sample the microphone at a rate higher then 8Khz? There's a definate lack of stuff for the DSP chip (ack'd by NeXT in their documentation) and I'ld like to play with the mike until I can get my hands on the DSP. I've tried sampling at 8Khz and then using sfupsample and sfmake but I'm sure that I can get better sound by sampling at 44 Khz right off the bat. Any clues out there? 4) I've indexed about 30 files into Jot. When I go into Jot and try to find the articles relating to, say, printing, I only get 1 or 2 of the articles. when I grep for the same string in my JotFolder, I find 10 or so. Is this related to the problem with the Library not finding all occurances of a given word? Anybody else had this kind of problem? Lastly, has anyone gotten the Optical disk usable by general users? I've hacked together a way, but it involves making disk, umount, and mount suid to root :-(, but those programs are only executable by the group optical. This is a security hole in that anyone in optical can trash any disks on the cube. Anybody have a better way? If anyone wants to see how I did it, send email.

We created a directory on an optical, did a 'sync, sync, eject' and had a trashed directory on the optical when we remounted it. From this I assume that the second sync doesn't wait on the first. BTW, I got a couple replies on how to initialize an optical with only one partition; the magic incantation is: disk -i -t omd-1-all /dev/rod0a. -- mike (carlton@ji.Berkeley.Edu or ...!ucbvax!ji!carlton) >From: swerling@caen.engin.umich.edu (Ace Swerling)
