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:

CVE-2015-8103: Critical remotely exploitable security hole in existing TurnKey Jenkins deployments

Thanks to ElColmo it has come to our attention that existing deployments of TurnKey Jenkins are still vulnerable to CVE-2015-8103, a critical issue that allows remote code execution by unauthenticated users.

This issue has been fixed with many others by the Jenkins project, as detailed in the  2015-11-11 Jenkins Security Advisory.

    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. Getting into the zone is not easy, but it pays off. The downside to the zone is that it raises your expectations from yourself and others so much you will never be satisfied by normal again. The upside is that you realize what you are truly capable of.

    In the zone, your mind is a blade, a ferocious form of violent, nearly malicious intelligence.

    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.

    On motivation

    Don't wish for the peak while you are still climbing the mountain.

    This is going to take as long as it's going to take to do it at a satisfactory level of quality.

    Mental shortcuts and trying to rush through the motions will significantly extend how long it takes to achieve this goal.

    You have to focus on the next step, and enjoy taking it.

    I suspect you are going to have miserable miserable time if you are praying for it to finally be over.

    Python's timeless principles of good software

    $ python -c 'import this'
    The Zen of Python, by Tim Peters
    Beautiful is better than ugly.
    Explicit is better than implicit.
    Simple is better than complex.
    Complex is better than complicated.
    Flat is better than nested.
    Sparse is better than dense.
    Readability counts.
    Special cases aren't special enough to break the rules.
    Although practicality beats purity.
    Errors should never pass silently.
    Unless explicitly silenced.
    In the face of ambiguity, refuse the temptation to guess.
    There should be one-- and preferably only one --obvious way to do it.
