Open source & community
Twenty-eight years of Linux (RHEL, SLES, Oracle Linux, Ubuntu, Debian), FreeBSD, OpenBSD and OpenSolaris: the things I wrote, translated and talked about along the way.

EnderUNIX
I was a founding member and core team member of EnderUNIX, a Turkish open-source group that wrote software, documentation and talks on FreeBSD, OpenBSD, Linux and Solaris, and promoted the BSDs and qmail in Turkey. The site (enderunix.org) is gone, so each item below links to the Internet Archive and to a copy kept here; the software also lives on in the EnderUNIX GitHub organisation.
