I have just released version 0.2 RC1 of my hardlink program. Compared to the 0.1.X series, the program has been rewritten in C, as Python was to memory-hungry for people with millions of files. The new program uses almost the same algorithm and has almost completely the same bugs as the old version.
The code should be portable to all UNIX-like platforms supporting nftw(). I have tested the code on Debian, FreeBSD 9, and Minix 3.

Over the last years, I have developed a variety of metapackages for managing the package selections of the systems I administrate. The meta packages are organized like this:
jak-standard
Standard packages for all systems jak-desktop
Standard packages for all desktop systems (GNOME 3 if possible, otherwise GNOME 2) jak-printing
Print support jak-devel
Development packages jak-machine-
The meta package defining the computer X Each computer has a jak-machine-X package installed.

Just because Julien did it, I moved my website to almost the same design now. Still using ikiwiki, of course. I’m still missing a few things, such as marking the currently active page in the menu, but I hope to get that done as well soon. Go to http://jak-linux.org/ to see it.

If someone in Germany (or want to send it to Germany [at low costs]) still has (new) Touchpads to sell, I’d buy one or two of them at the reduced price (16GB: 99€, 32GB: 129€), or take them for free.
I promise that I will not sell them to others. I’m interested in WebOS, in running Debian and/or Ubuntu on those devices (for the extra fun factor), and lend it to family members for surfing, etc.

Common licenses for software include the term “worldwide”. Now, what does worldwide mean? The problem with the term worldwide is that it is ambigous and depending on it’s interpretation, violates against DFSG 6 which states: “No Discrimination Against Fields of Endeavor”.
The reason: Space travel. If we take the term worldwide to mean “everywhere on earth”, the license becomes non-free, as it prohibits the use outside of this planet. Affected by this problem are the patent section of GPL-3, the Apache 2.

Yesterday I released version 4 of dh-autoreconf, fixing two bugs, and introducing a new feature: Patching ltmain.sh to make -Wl,–as-needed work.
For this new feature, run dh_autoreconf with the –as-needed option. dh_autoreconf will then patch all ltmain.sh equal to the system one (which should be all ltmain.sh files if libtoolize ran before or via dh_autoreconf). On clean, dh_autoreconf_clean reverses the patch again.
So, if your package runs autoreconf, and patches ltmain.

Yesterday was my 21st birthday, and I received all “Hitchhiker’s Guide to the Galaxy” novels, the five ones in one book, and the sixth one written by Eoin Colfer in another book. Needless to say, the first book weights more than an N900. I did not read them yet, so now is the perfect chance to do so. Yes, I did not know that 25th is towel day, sorry for that.

APT2
I did not write much code or merge much of my prototype code, but some things happened since the last blog post about APT2 specific things in August and I forgot to write about them.
First of all, I dropped the GVariant-based cache. The format strings were simply getting ugly long and were not very understandable, performance was just much too slow (needing more than a few nanoseconds for a package lookup is obviously too slow for solving dependency problems); furthermore, building the cache was also slow and complicated because we needed all attributes of an object at once to pass them to GVariant, leading to ugly API.
