DebConf 15

I am still alive and currently attending DebConf 15. Feel free to grab me for a talk. I am just shy, not antisocial.

Code name for Ubuntu 18.04 LTS

Every Ubuntu release gets an alliterative code name from Mark Shuttleworth. It is a composition of an adjective and an animal. The upcoming Ubuntu 13.04 has the code name “Raring Ringtail”. Since nearly the beginning, the code names follow the alphabetical order. We will reach the letter Z with Ubuntu 17.04 if no letters are skipped. Will we wrap then and begin with A again?

At UDS-R in Copenhagen, Mark Shuttleworth jokingly said between Jono Bacon’s introduction and Mark’s keynote speech, that vegetables will be used once we run out of letters. He proposed the code name for Ubuntu 18.04 LTS: Brilliant Broccoli!

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

How to purge Wine completely

I had Wine installed and wanted to get rid of it completely. I removed the Wine Debian package and what belong to it, but the Windows applications still appeared in the GNOME main menu. I removed the .wine directory and all local wine-related desktop files:

rm -rf ~/.wine ~/.local/share/applications/wine
rm -f ~/.local/share/applications/wine-* ~/.local/share/applications/mimeinfo.cache

Now there is no sign left that Wine was installed.

libkibi 0.1 released

The first version of libkibi is released. This library is designed for formatting sizes in bytes for display. The user can configure a preferred prefix style. Packages for Debian unstable and Ubuntu 11.04 (maverick) are uploaded.

It contains a README for developers and a byteprefix man page for users, which can be read with man 5 byteprefix once installed. Thanks to Stefano Rivera for writing the man page!

For a demonstration how this library used by an application can look like, read my previous post.
