• Software automated testing 123, an entry-level talk about software automated testing. Why you should be doing it (if you’re not already), some advice for test writing, some basic concepts and some basic examples (in Perl, but I trust it shouldn’t be too hard to follow even if you don’t know the language).
• Taming the Snake: Python unit tests, another entry-level talk, but this time about Python unit testing specifically. How to write xUnit style tests with unittest, some advice and conventions and some notes on how to use the excellent nosetests tool.
• Introduction to Debian packaging, divided in four sessions: Introduction, Packaging a simple app, Backporting software and Packaging tools.

Just a quick note about them: the slides shouldn’t be too hard to understand without me talking, but of course you’ll lose some stuff that is not written down, some twists, clarifications of what I mean exactly by different things and whatnot. In particular, the “They. don’t. make. sense. Don’t. write. them” stuff refers to tests that don’t have a reliable/controlled environment to run into. I feel really strong about them, so I wanted to dedicate a few more seconds to smashing the idea that they’re ok, hence the extra slides :-)

Enjoy them, and please send me any comments you have about them!

In the same way, I feel that the mere idea of having a programming-language-dependent packaging system is a broken idea. I know it has advantages, and I know that being specific to the language, some things work better or are more flexible, but I just don’t believe in that idea. Why should I use a different packaging system for certain things just because they’re written in Ruby? Why do I, as a user of those programs/modules, even have to know that there’s some Ruby-specific packaging system, that doesn’t integrate at all with my system’s packaging system, and mixing both leads to a mess?

Not only that, but Rubygems in particular is quite hostile to repackaging into a platform-specific packaging system. A lot of people only provide the gems for their software, which are harder to work with than “normal” tarballs. They also use their own conventions for directories, that break the FHS (for example) and basically only make sense in the context of Rubygems. In that sense, CPAN is much better (although I think using it for application deployment is a very bad idea, but that’s a different matter), because at least it installs everything in sane directories, it doesn’t change Perl in any way, and it’s not a special format, just a repository of easy-to-install, easy-to-work-with, easy-to-hack, easy-to-repackage “distributions”.

Why, oh, why?
