Must have tux case //at 19:04 //by abe
Waah, I must have one of these very neat tux shaped computer cases. And if Acme Systems once will also follow hubertf’s wish for a BSD daemon case, I must have another one. In Germany, you can buy them at Elektronikladen.
And after getting one, I can think about what to do with a Linux box with
a 100 MHz, 32 bit RISC CPU and 16 MB SDRAM. ;-)

Giving root access retroactively //at 18:59 //by abe
How often did you start to edit a file from your usual Unix user account and then noticed, that you only can save the file as root? I often did.
Sec
wrote a little tool named presto which helps in this situation on
FreeBSD. Initially only being a proof of concept tool to show that
write access to /dev/kmem is as good as
root access, the tool now has a useful purpose: Called from any editor
or other tool (e.g. via sudo), it gives
that tool super user privileges retroactively. So in vi, you just can type :!sudo
presto to save the opened file, even if only root can write to
it. (Works only with security level 0 or -1.)
Oh, and btw: Don’t use presto with Emacs. Emacs isn’t an editor for
one file…. ;-)
