setting up and using modern OpenGL 4.5 core context on X11 with EGL and xcb, without xlib or glx
// This is @mmozeiko's libx + EGL example ported to xcb + EGL
// Original code: https://gist.github.com/mmozeiko/911347b5e3d998621295794e0ba334c4
// It requires EGL_EXT_platform_xcb extension, so if your system is circa the end of 2021 or newer you should be fine.
// Also, I don't know if it works on nvidia. LMK if you test it
// example how to set up OpenGL core context on X11 with EGL
// and use basic functionality of OpenGL 4.5 version
// to compile on Ubuntu first install following packages: build-essential libxcb1-dev libgl-dev libegl-dev, then run:

First computerenhance.com homework with decoding some simple MOV instructions, written in Jai
// RTFM. Starting from page 160
// https://edge.edx.org/c4x/BITSPilani/EEE231/asset/8086_family_Users_Manual_1_.pdf
// NOTE: this leaks all the memory in the world, but maybe I don't care
// How to test: compile .asm files with NASM and then provide them to this program
// then compare the output to the asm source code. I'll make a proper testing harness
// in the future maybe.

An example of compile-time script in jai without producing an executable. You can use it like that instead of bash or python
#!/path/to/jai-linux
#import "Basic";
#import "Compiler";
#run {
set_build_options_dc({.do_output = false});
print("Hello!\n");

Напишите простую реализацию функции для разбора параметров командной строки (getopt). Полагаем, что нам требуется структура данных, содержащая заранее известный допустимый набор параметров различного типа - строки, целые, числа с плавающей точкой и т. д., а также признак, является ли этот параметр обязательным. Полагаем, что параметры могут пере…

Имеется вектор размера N. Необходимо разделить его на M < N равных частей (то есть чтобы количество элементов в каждой части было одинаковым). Части не должны пересекаться и должны покрывать весь вектор (исключение - допускаются промежутки от начала вектора до начала первой части и от конда последней части до конца вектора, но в этом случае необ…
