Indeed! It has given me great pleasure to have contributed in to libsodium, unbound, dnscrypt-wrapper, the Linux kernel, netflilter, and now: datum_gateway.

I see this software used in my products that my employer buys off the shelf sometimes.

No sats for that yet, but pleasure alone is why I tinker with things I get to use.

I remember on LKML a guy once wrote that he cleaned up ... a Makefile in Linux. He then said he's proud he can tell his kids that some CGI animated kids movies was made by artists using Linux (I don't know, Blender?) and that he had a tiny part in the making things used to create that movie.

See, I remember that guy :-)
