What can I say?
I am enthusiast of free/libre and open-source software, but my OSS track record is scarce.
OSS project that I'm involved in a bit (not a member):
Alpine Linux.
In the past:
SystemTap.
Some of my old notes that may be still useful for some of you:
linux tips,
math papers (PL).
In 2018 I think I'll finally start some small and infrequently updated blog. Stay tuned!
