  • InfluxDB - Build time-series-based applications quickly and at scale.
  • Sonar - Write Clean C++ Code. Always.
  • Zigi - Delete the most useless function ever: context switching.

  • PrusaSlicer

    G-code generator for 3D printers (RepRap, Makerbot, Ultimaker etc.)

  • OCCT

    Open CASCADE Technology (OCCT) is an open-source software development platform for 3D CAD, CAM, CAE. This is a clone of the official repository located on Please use official development portal for registering issues and providing patches.

    They integrated OCCT, so they do now have code to read STEP as part of the code base. Yes, I am aware it is tessellated right now (which is the obvious first step to make it work), but that can be changed in future. Point is: they now have at least half of the necessary code available.

  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Data Platform where developers build real-time applications for analytics, IoT and cloud-native services in less time with less code.
