md + lvm2
It's just beautiful what happens when you mix Linux md with lvm2. I just added two 15K 146G disks to my system. They show up as sdc and sdd. Now I do this:
for x in sdc sdd; do
parted /dev/$x mklabel msdos mkpart primary 0 100% set 1 raid on print quit
done
cd /dev; MAKEDEV md
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdc1 /dev/sdd1
pvcreate /dev/md0
vgcreate raid1 /dev/md0
for x in agriffis amg; do
lvcreate -L 50G -n $x raid1
mkfs.ext3 -L $x -O dir_index /dev/raid1/$x
echo "LABEL=$x /home/$x ext3 noatime 1 2" >>/etc/fstab
done
mount -a
Commentify contest
A little while back (in April), we had a contest on #noise that started with David's post regarding a script to comment out words in a C file. The general applicability of this script is questionable, but it was still a fun contest. Here are the instructions:
- Write a command-line filter which will comment out all matches of a pattern given on the command-line, reading a C program from stdin and filtering to stdout. Whether the pattern is a literal, glob, regular expression is up to the contestant.
- The filter should ignore matches that are already contained within a comment (including C++ style comments) or double-quoted string.
The existing gawk implementation on David's blog is an interesting starting point, though it doesn't fulfill all the requirements above.
