  • You’ll encounter math eventually. It could be as simple as implementing linear interpolation for a custom type, or understanding why a type is not suited for a particular application (e.g. never use floating points to represent money). If you delve into low-level networking, you’ll need a good understanding of binary/decimal/hexadecimal conversions and operations. If you go into game development or graphics, you won’t survive without a deep understanding of vectors, matrices, and quaternions. Any kind of data science is just math translated to a machine-readable language.

    In my opinion, knowledge of the basic concepts is more important than being good at actually performing mathematics with pen and paper. For example, if you need to apply a transformation to a vector, nobody expects you to whip up a program that does the thing. Instead, you should immediately know:

    • what a transformation is (translation, rotation, scaling, projection, etc),
    • that each transformation has a corresponding transformation matrix,
    • that you’ll have to deal with inhomogeneous and homogeneous coordinates, and
    • that you’ll have to combine the transformation matrices and the original vector.

    That abstract knowledge will give you a starting point. Then you can look up the particulars – the corresponding transformation matrices, the method to convert between inhomogeneous and homogeneous coordinates, and the process of matrix multiplication. I know because I failed calculus.






  • The reality is that, although there are quite a few standalone Wayland compositors, you don’t hear about most of them, because almost all of them suck in one way or another if you go beyond opening terminals.

    Oh, fuck off! I can barely use Blender because dragging a spinner control does something with the cursor that makes Hyprland shit its pants. It’s been fixed and broken several times. May or may not be related: Vaxry has expressed his disdain for Blender in issue notes. (edit) found it: https://github.com/hyprwm/Hyprland/issues/3270

    (edit2) I should also mention that Hyprland is the only compositor where this happens. KDE Plasma, Qtile-wayland, Sway, Wayfire are all fine.





  • “Some people deserve to be punished.” - Amos Burton (actor Wes Chatham), The Expanse season 2, in reference to an opportunist who had been enriching himself during a humanitarian crisis; comparing him to pimps that force kids and vulnerable people into prostitution.

    Full quote

    (after beating up an uncooperative person and threatening him at gunpoint, then getting confronted about it)

    I didn’t kill him. Not yet. He’s a bully, and where I come from, bullies take desperate young girls like your daughter and force them into prostitution. And when they finally get knocked up, they peddle them to johns who get off on that. After they have the kid, they push them right back out on the streets even before they have a chance to heal. And those kids, they use them, too. Some people deserve to be punished.

    Windows search bar

    I’m baffled that people actually have the news on the taskbar. It’s the first thing I kill on every install (not that I use Windows, but sometimes I need it in a VM). I’m not letting Minitrue force-feed me.
