System cleanup

Tonight was system cleanup day. Baobob showed me where are the gigabytes hide. The home directory got rid of huge, old VCS checkouts of various projects. Then it was time to look at the system directories. I cleaned my apt cache

sudo apt-get clean

and the cache from pbuilder. Then I found something that lead to this blog post: /var/log consumed 3.8 GB. The biggest files were

1.8 GB /var/log/kern.log
1.8 GB /var/log/syslog
4.3 MB /var/log/dpkg.log
1.4 MB /var/log/kern.log.1

Hardware review I

This month I built two systems with identical hardware component (except for the case). Here’s the list of components:

Cases often don’t meet my high requirements. Many cases are sharp-edged, bad designed (inside and outside), use cheep plastic, and/or vibrate, because the hard drives confer their vibration to the case. The Sugo SG02-F case is not perfect, but I will recommend it. The Silentium T11 case has no shard edges, but I won’t recommend it. Too much plastic and optical not appealing.

You probably have to replace the boxed CPU heat sink and use a better power supply if you want a silent system.

How well do these components work with Ubuntu 10.10 (and probably other recent GNU/Linux distributions)? Perfectly. Everything that I tested worked:

  • The USB 2.0 and USB 3.0 ports work with everything plugged in (mouse, keyboard, flash drives).
  • Audio works (only stereo output tested; 5.1 sound was available in Pulseaudio)
  • 2D and 3D graphics work with the free (libre) radeon driver (Compiz runs)
  • LAN works
