I am still alive and currently attending DebConf 15. Feel free to grab me for a talk. I am just shy, not antisocial.
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!
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
This month I built two systems with identical hardware component (except for the case). Here’s the list of components:
- Case 1: Silverstone Sugo SG02-F white
- Case 2: Arctic Cooling Silentium T11 white
- Motherboard: ASRock 880GMH/USB3 R2.0
- Processor: AMD Phenom X4 840 boxed
- Memory: Corsair XMS3 2x 2 GiB DDR3-1333
- Hard drive: Samsung SpinPoint F3 1 TB
- Power supply: be quiet! Pure Power 430W
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
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.
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.
For a demonstration how this library used by an application can look like, read my previous post.
In this Ubuntu cycle, I work on getting the units policy implemented. For this I wrote a library called libkibi. Here are some screen shots how nautilus looks like with libkibi. Some changes are highlighted in red.
The file properties will show the file size in base10 and base2:
PS: I failed to launch nautilus in English. Therefore the screen shots are in German.
PS²: You can grab the modified nautilus package for Ubuntu 10.10 (maverick) from my experimental PPA (at your own risk!).
Why you should use libkibi instead of g_format_size_for_display (from GLib):
- the users can configure their preferred prefix
- rounds correctly (converting an integer to double, do some math, and then round again leads to rounding errors)
- complies to Ubuntu’s Units Policy (except “historic” is selected)
- is faster (between 15% and 35% depending on the processor)
Yesterday I became Debian Developer.
I already used my new @debian.org mail address for uploading a vlc security fix to unstable and audacious & audacious-plugins 2.4.2-1 to experimental.
