Weird! Whatever works, I guess. Ha ha.

Okay, assuming you have the developer tools installed, you should be able to use SetFile to make sure CoreServices isn't invisible. Try this in the Terminal: /Developer/Tools/SetFile -a v /System/Library/CoreServices

I've had this happen to me on occasion. I have a suspicion it's got something to do with the column view preview pane not properly releasing a resource on the disk. But quitting the Finder almost always works.

That's because /Library/CoreServices doesn't exist. You want /System/Library/CoreServices I think. ;-) And if for some reason that directory is set invisible as well, just use something like good old ResEdit to make it visible. Though I'm sure someone can suggest something a bit more...

Well, the #1 reason to spoof your wireless MAC address is to gain unauthorized access to a network (assuming you've also cracked the WEP/WPA key if there is one). So we're going to need a bit more convincing than that. ;-) And frankly, I wouldn't be surprised if the AP Extreme card just...

Okay, I'll grasp feebly at an explanation of the difference. STDERR is used mostly for displaying status messages related to how the program is functioning. STDOUT is typically used for the actual meaningful output produced by the program. So for example, if you're tarring to a file, you...

Oh, one more thing: this launches the file server daemon, but it doesn't start up the other daemon that advertises the service over Rendezvous. So don't be startled that it doesn't show up.

No, but you wouldn't be able to do that from the Terminal either without proper access privileges. Oh, and it completely slipped my mind how easy it is to get to a shell: 1. Logout 2. Enter the username ">console", with no password, and hit enter 3. Login 4. Fun Or just reboot the...

Well, there's the "do shell script" instruction in AppleScript, for one. I'm sure there are plenty of other ways to launch a process, too.

As it turns out, this is insanely easy to do. To start AFP: sudo AppleFileServer To stop AFP: sudo killall -TERM AppleFileServer And that's it.

I don't suppose you're running something older than 10.3, are you? This is what the usage message looks like on my system: usage: gcc_select [-n] [-force] [2 | 3 | 3.x] [-h | --help] [-v | --version] [-l | --list] [-root] I'll bet you just need the updated developer...

Was crt1.o just some object file you had in the current directory that you wanted to link into the program you were compiling? You don't need the "-l" flag for that. Just specify it like this: gcc mainfile.c objectfile.o -o theprogram You just have to put .o files as arguments to gcc, like...

It looks like the 10.3 version of chsh properly handles the netinfo database (as opposed to operating on /etc/passwd), so the answer is a qualified yes: you have to be able to use vi well enough to edit the config info it gives you. Heh.

This is actually easy to prevent using the "stick bit". From http://www.kingcomputerservices.com/unix_101/security_basics_part_2.htm: So chmod your drop box to 1733, and users won't be able to screw with the other users' files in the drop box. In fact, the /tmp directory is set up...

It depends on the permissions user B set on the file (likely automatically). In that example, it's like this: Owner (user B): read, write, execute Group: read, execute Everyone: read, execute The default umask is 022, meaning files will be created with permissions 755 (like the example)...

Hmm. I guess the only way to find out for sure would be to run Ethereal for a couple hours (NOT in promiscuous mode) with the filter "udp port domain". Maybe then we'll get some concrete clues. I'd do it now, but it's just about bed time. Heh.

Hmm, very interesting... It works fine for me at home, and that location has the DNS server addresses specified manually (so it'll play nice with my router). But on campus, I have it defined automatically. I just now put in the specific server address, so we'll see what happens.

Do you have the ability to Hotsync this palm with the Mac in question? If so, download iSync, and also the iSync Palm Conduit. http://www.apple.com/isync/download/ The conduit link is kind of buried in the sidebar along the right. Once you've got those installed, set up the conduit in...

You'd think that user A wouldn't be able to access the file he put in the drop box - after all, shouldn't a drop box be write-only? But because of limitations of the user/group/other read/write/execute permissions that OS X uses, that cannot be implemented easily. The drop box will have...

Yeah, like I said, it's pretty much a limitation of the basic Unix permissions. In order to set the directory so that a user can create files in it, the user will also have to be able to read said files. And theoretically, if another user's UMASK is such that files he creates in the drop box are...
