I decided to shut down most of my projects. All existing static content (text, audio, video) will remain available for as long as possible. Any running code will halt by the end of September. Open source code will remain available on Github.

Here is the complete list:


  • Geostreaks. iOS app for those who work from home and forget to go outside. (Will remain available on the app store for as long as possible.)
  • Search engine for developers.


  • EmacsCast. Podcast about Emacs.
  • Codexpanse Podcast. Exploring the computing nature of reality, ideas of programming and math, and our role in this exciting world.

I'm also stopping my contributions to all collaborative projects.
