The Tragedy of systemd

An interesting talk on the history of init and systemd across various different flavors of unix. Touches on software history, how things end up the way they are, and how we respond to change. I am not immersed in this particular unix community, but this talk does a good job of hinting at the later contours of that community.

What Even is SELinux?

I cam across this surprisingly cogent explanation of what SELinux linux is, including a bit of history about where it came from. There’s probably a paper to be written about the various attempts to improve and build on top of the simple-yet-complex chmod/chown/chgrp permissions scheme at the heart of unix.

Service Decorators in Practice

While this isn’t a straight up decorator tutorial, it does describe a practical application of the pattern which (unlike most of the decorator pattern documentation I’ve read) is a decent way of getting your head around the who/what/where/when/why of this pattern, particularly if you’re interested in Symfony’s [...]

It’s unclear if the [...]
