Description

One of the PuppetLabs guys is trying to enforce best practices on administering Puppet modules, by using base modules and build services and roles on top of them. That way we can re-use external / third-party modules from forge.puppetlabs.com, ideally without touching them at all. He names that "the Lego approach". Full article.

Setup and operate a Mode-S Beast that receives the ADS-B broadcast signals sent out by airplanes.

Building on top of <a href="http://rdimitrov.twistedsanity.net/blog/show.php?entry=Microcontroller%20Class%20D%20Amplifier,%20Rev2">Rouslan Dimitrov's Microcontroller Class D Amplifier</a>, I developed the idea to feed the power amplifier with PCM data directly. Rouslan does some dithering and noise shaping, but I'm convinced that proper interpolation would sound better. The ATtiny is too slow to do even cubic interpolation so I'll move that into the host.

The bootloader menu has to be able to list snapshots created with tagged attribute by snapper or other tools. These attributes control how snapshots are displayed and organized in the boot menu. All the changes are reflected in real time, that is when a snapshot is created it's ready to boot without the hassle to call grub2-mkconfig to refresh menu. The operation and navigating to the snapshot is intuitive and out of box and booting is even more easy to hit the button. The hackweek is based on current implementation to improve the code structure and testing, like code clean up and make it in better shape get upstreamed, improving the menu to use extended attribute to organize the boot menu with defined attributes which can be tagged by snapshot tools like snapper etc.

QADB is the database used to strore results of automated tests in SUSE QA. It only has web intrface, which is mostly just a better DB view. The goal of this project is to create the REST API to it, which can later be used to query for results from external tools (and maybe even later used by the frontend)
