If you want to understand how 3D projection works, it’s better to solve a few trigonometric equations by hand on a piece of paper, then copy these equations to your Python code.

If you just want to quickly make your own 3D renderer, simply use OpenGL API and the corresponding projection matrix. It will run the same exact formulas inside the driver, just in a 4x4 matrix form, and you can simply experiment with modifying each element of your projection matrix to make your 3D scene rotate the way you want, without bothering to understand the math.

Simply copying some formula from the net will most probably fail.

C++ with -Wall -Werror, and no pointer diddling.

You run it inside DOSBox on your Linux installation, simple!

Extend C++ for safety

I stopped reading after this. Why do you think C++ is unsafe in the first place? Someone decided ro extend it, and now you cannot even read an error message without finishing an university course on lambda calculus first.

Back in the 80386 days there was one model of BIOS that would print ‘CPU not found’ if you had your CRT monitor and VGA videocard plugged in.

It’s either a fairy cosplay, or a moth fursuit.

They probably moved the wall after the toilet was already installed. That half-obscured window covered with plywood above the toilet is telling enough.

It’s about C89 standard, eww.

Ask the guy to hold down the wolves while I teach them how to install Debian

You also have CLOCK_MONOTONIC, which could or could not be the number of seconds since last reboot.

To be honest, this mess was directly inherited from POSIX C system calls.

Seeing RISC-V and VHDL mentioned in [email protected] why am I not surprised. I feel like another community would be better suited for RISC-V study, like [email protected]

It’s false that you cannot sell GPL-licensed work.

Busybox was quickly replaced by BSD-licensed Toybox everywhere for that exact reason.

Copyleft licenses (like the Gnu General Public License) mandate that all derivative works remain free.

This is false. It’s perfectly legal to take GPL-licensed work, modify it, and sell it. As long as the work itself does not reach the general public, you don’t need to release it’s source code to the public (e.g. your work for the military, you take money for your work, and provide source code to them, but not release it publicly).

The first one is a fancy CPU warmer. The second one will play loud noise through your headphones, and setsid will make sure you can’t stop it with Ctrl-C.

There was a thread about console commands seen in movies or TV, when the actors need to do some ‘hacking’ on camera. And the most common one was just installing updates to your Linux distribution of choice.

My go-to joke is

cat /dev/urandom | pxz | grep haxx

Or if you want to be nasty

setsid sh -c 'cat /dev/urandom | pacat -p'

As for puns, less command does the same thing as more on MS-DOS.

tar c file | pxz > file.tar.xz

Play Store link?

I’ve used FreeBSD for about a month in 2005, and still can’t stop talking about it.
