If you're in the Cambridge, MA area or already planning to attend the LibrePlanet 2018 free software conference, come learn about functional package management at my talk: Practical, verifiable software freedom with GuixSD.
Abstract:
GuixSD is a GNU/Linux distribution built from the ground up to empower users to exercise the four freedoms they've been granted by free software. In this talk, you will learn how GuixSD makes it easy to inspect source code, share source code and binaries and even entire system configurations, verify that binaries were built from the source they claim, customize software packages, and experiment without fear of breaking your system.
LibrePlanet is being held at the MIT Stata center. My talk is on Sunday, March 25th, at 3:25pm.
