No need for crossover cables anymore, (yay) and a couple of simple NetworkManager commands are all that is needed.

Fixing the network performance of a very specific laptop wifi chip pretty easily (especially for NetworkManager).

Currently the best approach on my Lenovo is the parameter set:
modprobe rtl8723be fwlps=0 ant_sel=2 ips=0 swlps=0 swenc=0 disable_watchdog=0

But it also worked with other configurations and does not seem stable. Some suggest turning swenc and swlps on for better perfomance.

Very complex examples for YAD (a zenity fork), standing for yet another dialog.

Creates full option menus and a search window!
I live more in the console, but this is still very impressive.

Completely walkthrough operations manual -- with various considerations along the way.

A key remapping daemon for linux. Contribute to rvaiya/keyd development by creating an account on GitHub. Allows even easier remapping of capslock to escape/ctrl, just like xcape.

Works on any compositor / display server since it works at a system level.

extended xcape alternative, also working under wayland. Can be used to remap any key to output any key (combination) on single tap or long hold. Can also be configured for special double-tap setting that I have not fully understood yet.

Fully functioning wayland environment with many different pre-chosen applications (image viewer, screenshot grabber, clipboard manager, etc).

Intended for nixOS but the choices can give hints as to how to setup a working wayland environment.

Enhanced, modular, bookmarking for newsboat, newsbeuter, or (for that matter) anything that can pass a title and an URL to a program - even from your clipboard.

Chill is a bit of a stretchy definition for this one, (e.g. Celeste might be a cozy adventure but rarely chill gameplay, Owlboy is also very hype)
but they are at least generally in the chill-comfy-cozy zone for much of their runtime

A giant list of older games re-implemented or made to work natively on Linux with Luxtorpeda (a steam compatibility tool, nicely selectable from within Steam itself).

Webtop - Alpine, Ubuntu, Fedora, and Arch based docker containers containing full desktop environments in officially supported flavors accessible via any modern web browser.

You simply navigate to the hosted page and can instantly work in your favorite linux environment --- this seems extremely futuristic. And could be useful to many (I am thinking e.g. of using Windows-only library PCs or doing something at a family's/ friend's house).

Several options that can be set simply through a single file variable for systemd logind.

Simple, efficient and pretty.
A minimal GUI Journaling application - it gets out of your way and allows you to write in markdown.

One neat feature is its calendar view which lists the quick titles of your journal entries for days passed and thus gives you an overview of what you did when and when you were journaling.

If you need a terminal equivalent use jrnl instead.

A comprehensive beginner's guide to setting up Arduino programming from vim and the commandline.

Starts with sample blink program, with classic Arduino board,
but quickly moves on to usage with an ESP8266 (so, easily adaptable to ESP32 boards) and with an included library (in this case Adafruit Neopixels).

A quick guide on how to update xps13 wifi card firmware to newer versions.
Should rarely be necessary since they get merged to the kernel sooner or later,
but might nevertheless be useful.

Many many Linux softwares. Mostly useful as an overview for someone looking for a software in a specific area of computing (audio engineering, writing, database editing, programming, ..) since they are nicely sorted and allow an overview of FOSS alternatives to various software needs.
