Play Youtube (and many other) Media Links from your Browser with One Click
Make sure mpv is working with local files. Regardless of this article, mpv is about the best media (video) player available for Linux. It will automatically detect if youtube-dl is in your $PATH, and use it to play web URLs. So now all you have to do is to add an entry to Open With settings to open a link with mpv.
Make a screencast with ffmpeg
Several applications to record your desktop exist, but ffmpeg can do it all by itself, via its x11grab format specifier. But there were some challenges: What ffmpeg does when recording your screen is to transcode the X11 video into compressed output, based on file extension.
Customizing the Linux Console
A collection of tricks that also have an effect on the non-graphical environment, a.k.a. the console. I do not use a display manager or splash screen. When my computer boots, I see all messages, then a login prompt. By default the screen would clear before the login prompt shows up, but I have disabled that.
Arrange long Command Output in Columns
There's this one command whose output you need to look at again and again. It's a long list of short words and whizzes by too fast and using your terminal's scroll function is cumbersome. Of course there's more or less, but that is cumbersome, too! Searching the web for a solution only leeds to more complex problem, until on the third try I found column.
Convert man pages to HTML with the Ansi Html Adapter (aha)
I was having a hard time trying to find a man-to-html converter that does what I want: just properly translate what little formatting man uses. What I found (groff, troff, roffit, man2html) seemed to be either outdated (using inline- or even html-styling) or buggy or simply unable to preserve man's formatting.
Window Managers
Linux is somewhat famous for having so many different windowmanagers; this is not a complete list. My interest was in those that I also have a special interest in those that can do both floating and tiling, but not all windowmanagers presented here fulfil that.
Xmountaincolors
It's like Xmountains, but with configurable colors. See the Xmountaincolors project page on notabug or framagit. Screenshot Gallery Here's an example of what the original xmountains looks like (It is still possible to use xmountaincolors in this way by simply not providing a theme name).
Download all files of (a) certain type(s) from a website
If you get a "Forbidden" error for certain folders, it might help to start at the root of the site. This will download all playlists for all soma.fm radio stations into the current folder, omiting low-quality 32 and 24kbit/s stations. Should work with other sites containing playlists.
