"A bit of theory, a bit of C, a bit of Bash

But makes you crunch at night until your crash"

What's inside (in a nutshell)

1. Problem Set
   • Isn't there cause it's just theory about bios/uefi/gpt/mbr/partitions/kalilinux/vbox/ubuntu...
   • ... and some more about the scrapyard that heats my dorm room if I will turn on Witcher 3 on High.
2. Problem Set
   • All Console Colors Printer
   • Script that turns everything to lowercase in a catalog

   • Signals Theory Stuff with programs to prove it
   • Own variation of unix shell
5. Problem Set
   • Own implementation of printf w/o use of libs and macros (like va_start, va_arg and va_end) [32bit]
   • Multihread matrix multiplication of two random matrixs
   • Minitalk (server-client messenger w/o using threads and forks with simple login and private messages)
   • Matrix multiplication and optimalization of that proces
   • Creation of FAT and VFAT and then theory and then recover deleted files manually (theory)
6. Problem Set
   • Asm program for proc6502that prints 8-bit number in hex
   • Asm program that looks up for primes in bounds from 1 to 10000
   • Asm program that calculates simple stuff and prints it
   • Asm program that that counts n! on 128bits
   • Asm program that draws Mandelbrot set
