New server case sucks! Part one

ube — Mon, 17 May 2010 13:55:58 +0000

Well, been a long time since I did anything computer related, at least something that takes more than five minutes to fix (excluding surfing the web from my couch). But now I decided to replace my Antec P182 case with a Chenbro ES34069.

I've been looking for a mini-itx case and was considering on going for some atom based mobo, but then I found the ZOTAC G43-ITX SOCKET 775 MINI-ITX which has everything I need to convert from my old system: 5 SATA ports and socket 775. So with a little bit of luck I can use my "old" Q6600 processor. The specs for the mobo states only 65W TDP but I've found a post at their forums stating that with sufficient cooling everyting "should" be ok. So problem one done.

Problem two:
I need to find a low profile heatsink that supports 95W processors. I should probably get the Chenbro case and the mobo and then do some measurements on which height the heatsink can have.

Found this build description online so I know what I have to look forward to for now.

Perl 5.8.8 sucks, or the lack of Perl 5.10 on my box sucks! Really

Been struggling with a regexp using perl since I couldn't get sed to work as I wanted (mainly "+" sucks with sed).

These are my tests:

# echo cold.case.S01E12.qweqwe |perl -pe 's/^(?:(.*)\.(\d+)x(\d+).*)|(?:(.*)\.S(\d+)E(\d+)).*$/\1 \2 \3 \4 \5 \6 \7/'
cold.case 01 12
#echo cold_case.1x12 | perl -pe 's/^(?:(.*)\.(\d+)x(\d+).*)|(?:(.*)\.S(\d+)E(\d+)).*$/\1 \2 \3 \4 \5 \6 \7/'
cold_case 1 12

Notice the three spaces in front of cold.case? It's because I can't get perl to do an alternate match. A friend came up with the following line:
perl -pe 's/(?:^(?.*)\.(?[0-9])+x(?[0-9]+).*$)|(?:^(?.*)\.S(?[0-9]+)E(?[0-9]+).*$)/$+{a} $+{b} $+{c}/'
Which works just fine, if you're running Perl 5.10, and I'm not! Or, it's not in the Gentoo repository yet. So I'll have to wait. Crap!

mdadm sucks

A couple of months ago my box at home died. I came back home for vacation two days ago and started to check why it doesn't start.. One of the disks had been marked as failed (or acctually two, but only one is dead), I was wondering of removing all the data by re-creating the array and scrapping ~3Tb data.. But when I woke up from a nap this evening I thought that maybe the -f flag works with mdadm as well:

# mdadm -A -f /dev/md0 /dev/sd[acdefgh]1

Did the trick, it resetted the failed status on sdh1
