systemd sysv init compatibility mode: how it works and troubleshooting when it breaks

systemd sysv init compatibility mode is magical. That is in the sense that it tries to handle compatibility with sysv init scripts while you are distracted looking somewhere else.

When it works it works well, but when things break it makes troubleshooting more difficult. Especially if you don't understand what's going on behind the curtain.

The first thing you need to understand is that this probably doesn't do what you expect:

Keeping track of time

For the last few years I've been using a nifty little program called gtimelog to keep track of how much time I am actually working (and in a basic way on what), and how much time I am off work, whether it is for a meal, a personal phone call, random web surfing etc.

Getting into the zone - Crazy tips for maximum productivity

The zone is a mysterious place familiar to deep thinkers. It is a mode of consciousness in which you are almost superhumanly intelligent and productive. Hard problems are solved in the zone.

13 simple writing tips
