Fit-PC

For a 500MHZ CPU it performed as you would think. I bit slow to open/close apps and rendering websites. Video playback from the samples they provided did great.

The Bad

The audio only came out of the left speaker. I found this post
http://fit-pc.com/forum/viewtopic.php?t=227&highlight=audio
in the Fit-PC forums and it helped. However, I had to do it several times and finally I made the adjustments while the unit was powered on, not recommended, and kept testing it while putting the back plate back together.

I may have sent it back if I wasn’t going to use this as a server. Hopefully they fix this part or decide to use another in the near future. If I were using this as a multimedia device that required sound I would have sent it back.

Update

Fit-PC sent everyone from that forum new cables to install. You also had the option of sending you unit back to them to fix. I haven’t done mine yet, since I don’t use audio, but did receive my cables.

GParted

Partition #1, ext3, /dev/hda1 – 3.26GB
Partition #5, swap, /dev/hda3 – 768.74MB, (3*memory) for good measure
Partition #6, ext3, /dev/hda2 – 33.25GB, for /home dir

Later I added a partition for /www and /mysql @ 9GB

Remove the CD drive from apt get

Comment out the CDROM stuff at the top. This way it won’t ask you for your installation CD, “Media change”, and will download the stuff you need. Now you can trash that ISO or CD.

take a look at /etc/mysql/my.cnf
there is a [mysqld] section where you can change the datadir location

steps (not tested!):

1- stop mysqld, sudo /etc/init.d/mysql stop
2- backup your datadir
3- restore the datadir to the new location with mysql permissions
4- change /etc/mysql/my.cnf to specify the new datadir location
5- restart mysqld

Backup scripts for /home, /var/www

For MySQL

mysqldump
or
http://dev.mysql.com/doc/refman/5.0/en/mysqlhotcopy.html

Edit /etc/sysctl.conf and add this line to the end:

vm.swappiness=0

I know the previous one said 10, but 0 really cuts the usage down a lot. I changed mine to 5 and don’t see any change.
