OpenROCS v2.0

OpenROCS v2.0

OpenROCS is an independent control layer for robotic observatories: a master scheduler that runs routine operations to maximize scientific return, while monitoring and reacting to anomalous situations that could put the facility at risk. Every application and hardware component at the observatory interacts with it. Released under the GNU/GPL license.

Sheet music for gralla

Sheet music for gralla

This site is a catalog of sheet music for gralla. I obtained the 250 initial scores from the web gralla.skamot.com in encore format and using free software, I converted them to lilypond, pdf, midi and mp3. Currently everything is published on github and the online application is 100% javascript

RhinOS

RhinOS

RhinOS is the perfect tool for building a professional website, managed in an easy and dynamic way without needing technical knowledge. Born from the same project as SaltOS, it still receives updates to keep running on the latest PHP releases. Released under the GPL-3.0 free software license.
