Loki Re-Indexer
This was a research PoC for a customer. Back when I wrote this, we realized that Loki has a significant flaw, that's problematic in several scenarios: If you do a hasty reconfig, you'll loose your index and won't be able to rebuilt it. You're left with the data, but cannot access it. This re-indexer enables a series of operational improvements, e.g. easier off-site backups. This sadly never made it upstream. [Github Repo]
Org-mode ox-epub
Epub support plugin for Emacs Org Mode. The only 100+ Star repo I have today. I have not been maintaining it for some time. [Github Repo]
Guix on AWS Packer Bootstrap
Smaller custom engineering to bootstrap the GNU Guix Linux distro on AWS. This was a personal test balloon and a step into immutable and reproducible systems/builds. [Github Repo]
Jenkins CI - Durable Task Plugin
Powershell Profile Loading [Github PR].
Cloudformation Support for Sphinx
Custom out of tree plugin [Github Repo].
Public Radio skill for the Mycroft Voice Assistent
Custom out of tree plugin [Github Repo]. Unknowingly (to me) this skill actually made it into Moritz Metz' show "Netzbasteln" on national public radio (Deutschlandfunk). Fun thing to do, but failed on this "demo day".
