Notes

Random

• To enforce a particular directory as the root directory for Pytest, just drop an empty pytest.ini file into the directory that you want to be the root directory.
• To ensure that a GoCD pipeline can only run based on timer and never on a material, mark the first stage of that pipeline as manual. Or mark it as manual in the template itself.
• Idempotency is an essential feature of automation software like Ansible and FreedomBox. I wonder if there's a way to write a test suite that checks each action in the system for idempotency.
• Download a youtube playlist using

  $ youtube-dl -t <url>

• Android activities are destroyed and recreated on screen orientation change. To avoid this, set

  android:configChanges="orientation|screenSize"

  under the Activity tag inside the AndroidManifest.xml. This only works if the minimum target version is API 13 or more.
• To add a location to bookmarks in Nautilus file manager (default in Gnome 3), navigate to the directory and press Ctrl+D
• Use org + LaTeX Beamer to rapidly create presentations. A simpler tool is mdp (markdown presenter)
• Lektor builds a website by taking all the files in the content/ folder, processing them according to the rules of your Models and rendering them by using templates.
• Create a REPL inside a Clojure REPL

    (defmacro loop_ [& body] `(while true ~@body))
    (-> (read) (eval) (println) (loop_))

• Setting permissions after copying the file will lead to momentary exposure of the private key to other users on the system. Use umask instead.
