Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Why most people recommend to reduce swappiness to 10-20?
Because most believe that swapping = bad and that if you don't reduce swappiness, the system will swap when it really doesn't need to. Neither of those are really true. People associate swapping with times where their system is getting bogged down - however, it's mostly swapping because the system

KDE, QT, GTK, TK, all in several versions and with changing variables and whatnot at every version, and even within a single version.
One would think that QT and KDE are more or less the same, but turns out that, at least from outside KDE, one can't fully define the theme settings (or UI font specifically) from KDE's "appearance" settings. Even for apps that aren't "standalone QT", but KDE! Like fonts on konqueror, and probably dolphin too. KDE has a longstanding...

Whereas gtk-qt-engine doesn't work very well, that is, GTK can't be easily made to "simulate" QT/KDE themes, the converse seems to work very well, and apparently no additional package is needed for that, but QT alone, or actually just qtconfig-qt4, in order to set the QT/KDE* theme as "GTK+".
So one third of the problem of desktop uniformity is solved if you have one GTK2 (I believe it's GTK2, not 3, I'm not sure) theme that you find good enough to have both in...

("bugfix")
Sometimes you open an application that will in turn open some web page, and it will automatically open it with the default browser. The problem is that often you'd prefer that it had been opened in whatever other browser that may be already running, even if it's not the system's default. So I came up with this script in order to try to get this behavior:
Code:
#!/bin/bash
# This "software" (so to speak) is totally UNLICENSED and barely documented. What you see is

Zswap is basically like a "fake swap partition" inside the RAM itself, but instead of just "moving" things from one place to another in the RAM, these things are compacted, instead of being written to the actual swap partition, on the HDD. Or so I understand. It then squeezes more out of the RAM than with non-compressed use, at some cost of CPU due to the compression/uncompressions, and monitoring, but sparing access to the swap partition on the HDD.
