oxbar - configurable X11 status bar for OpenBSD
> oxbar is a X11 status bar for OpenBSD showing various system stats. It has a configurable display and works out-of-the-box on most modern window managers in an intuitive fashion. oxbar supports FreeType font rendering and styling, true transparency & alpha blending on all UI components (including the root window), and a simple configuration format that can concisely support multiple themes.
Understanding X mouse cursors (and their several layers of history)
> The X protocol (and server) come with a pre-defined set of cursors. If your program is happy with one of these, you use it by telling the X server that you want cursor number N with XCreateFontCursor(). As mentioned in the manpage (and hinted at by the function name), the server loads these cursors from a specific X font, which is exposed to clients under the special font name ‘cursor’. Like the special ‘fixed’ font name, this isn’t even a XLFD font name and so there’s no way to specify what pixel size you want your cursors to be in; you get whatever (font) size the font is or the server decides on (if the X font the server is using is one where it can do that, and I’m not sure that the X server even supports resizable fonts for the special cursor font).
gter - a terminal for GUI apps
A shell may be more accurate?
> The goal of Explanations is to try to allow people to play with fun parts of computers. Graphics, compression, audio. The tagline is my biggest inspiration: “Play, don’t show”, riffing off the typical “Show, don’t tell” rule of writers and authors everywhere. Why bother giving a diagram when I give you an inspector and let you poke at things yourself!
> Previously, this series was known as “Xplain” and was more focused on the X11 window system and protocol, but I’ve been slowly moving towards anything that interests me, and I’m hijacking this project for it since I really like the format and style I’ve developed. The code for every single one of these demos is available in the GitHub repo, and I do try to comment heavily and go into even more depth there! Play with the code! Use it for one of your own projects! It’s all MIT/X11 licensed. I very much appreciate followup questions and any sort of feedback through the links mentioned above.
> You might have noticed that when you ran your mouse over the stipple, your cursor changed. That’s because this isn’t just any old stipple image, that stipple is actually the background of a full X server session running in your browser using HTML5 canvas. All of the interactive demos will use this framework to explain what’s going on under the hood.

What I want out of my window manager
> One answer to what I want out of my window manager is ‘fvwm’. It’s my current window manager and I’m not likely to switch to anything else because I’m perfectly satisfied with it. But that’s not a good answer, because fvwm has a lot of features and I’m not using them all. As with everyone who uses a highly customizable thing, my important subset of fvwm is probably not quite the same as anyone else’s important subset of it.
The 80/20 rule rears its ugly head.
Some things about where icons for modern X applications come from
> Although I don’t know how it was done in the early days of X, the modern standard for this is part of the Extended Window Manager Hints. In EWMH, applications give the window manager a number of possible icons, generally in different sizes, as ARGB bitmaps (instead of, say, SVG format). The window manager or desktop environment can then pick whichever icon size it likes best, taking into account things like the display resolution and so on, and display it however it wants to (in its original size or scaled up or down).

Computers suck: episode 17787 of 31279
> And so began my epic journey into the wild and uncharted jungles of the Linux keyboard system. Or should I say systems. I wish I could draw you a map here, but I don’t have one. All I know is, I wandered about through many strange lands, having adventures. Please do not assume that anything in this article is technically correct.
Integrated development window manager
> There is an integrated development window manager where you can: Select any compiler error text in any terminal and open the correct file and line in your text editor. Click on the output of ls in any terminal and open the corresponding file with the correct program. Click any url from any text on your OS and open it in your browser. What if I told you it is actually just a 100 line shell script?
X and NeWS history
> As the guy who single-handedly prevented X from becoming an ANSI standard, I’d be happy to start another thread on this topic if people are interested.

Toward a More Useful X Keyboard
It’s X, so there’s only about a dozen ways to configure things. But at least you can make it do what you want eventually.
Scrolling with pleasure
> Although the article contains a great deal of technical details, I hope that it will be interesting not only to computer programmers, but also to people who wonder how scrolling works under the hood, why we have what we have and how we can make the scrolling better.
