Reboot to {OS}

This a collection of notes and files used in my quest to create "Reboot to Windows" and "Reboot to Linux" scripts (and desktop shortcuts) for Linux and Windows respectively that automatically reboot my system and instruct rEFInd to auto-select the appropriate OS entry.

General Information

The key for achieving this is to modify the EFI Variable PreviousBoot with GUID 36d08fa7-cf0b-42f5-8f14-68df73ed3740, which rEFInd uses to store the last entry selected in the menu and, if using the + default entry, will be used to select the default OS. By doing this, we trick rEFInd into booting the OS we choose without having to be physically there to press the keyboard.

Get Icon Theme in Every Desktop

If you've ever tried to manually look for the current icon theme, you've probably come to the (correct) conclusion that it's simply impossible to do it in a portable way: each desktop environment in existence stores that information in a different place, and it's none give out that info in a common way.

In order to find out the current icon theme then, we first need to find out the current desktop environment and only then we can get the current icon theme in a desktop-dependent way. To do that, we can use the following environemnt variables:

• XDG_SESSION_DESKTOP: contains the name of the current session name.
• XDG_CURRENT_DESKTOP: contains a :-separated list of current desktop names.

Factorio Server on Dokku

This document and associated files describe a very simple procedure to push a Dokku application that will launch a Factorio Multiplayer Server. This are the actual files used to launch my Factorio server, so you should trust that it works.

    ./capture [-h] [-p period] [-d directory]

* Use **-h** to print the above usage line.
* Use **-p period** to specify the period of the screenshots, in seconds. The *period* argument must be a positive integer. Defaults to *15* seconds.
* Use **-d directory** to specify the directory where the screenshots will be saved. The specified directory must exist and be writable. Defaults to the current working directory (which may be not writable, which won't cause an immediate error, but will make scrot fail).

In order to this script to work, you need to have the `scrot` command installed on your PATH.

The script may be paused by sending an interrupt signal (`SIGINT`), typically by pressing the `CTRL-C` key combination. When the script is paused, you may resume it by pressing `ENTER` or end it with another `CTRL-C`.
