os-tutorial is an open source educational project by cfenollosa that teaches the basics of building an operating system from scratch. The repository provides step-by-step lessons starting with bootloaders and moving through kernel development, interrupts, memory management, and system calls. Each tutorial is accompanied by clear explanations, code examples, and references to deepen understanding. The project uses x86 assembly and C to illustrate concepts, making it accessible to students and...

...GitHub repository: https://github.com/Northstrix/onda-sfasata Check it out at: https://onda-sfasata.netlify.app/ This app is fully localized into English, Hebrew, and two dialects of German — Hochdeutsch and a mixture of Zurich and Basel dialects (approximately 64%–36%), labeled as “Schwiizerdütsch” I picked the words for this app not based on predefined categories, usage frequency, or the fluency level to which the word might correspond, but on which words could be cleanly cut from the audio tracks. As a result, the word set turned out to be a bit odd, yet unique. Every single sound used in the app, except for success.wav, error.wav, and completed.wav, was extracted from public domain recordings. The success and error sounds are covered by Attribution 4.0 License (https://creativecommons.org/licenses/by/4.0/), the completed sound is available under Creative Commons 0 License (http://creativecommons.org/publicdomain/zero/1.0/)

...The emulator brings back memories from the 1980s, offers graphical features like sprites, character generator, 16-color palette. One goal is to create a framework for making games with 8-bit look and feel, including the process of programming. The programming tutorial helps beginners enter the world of programming in a gamified way.

...Draw a binary integer from a cell going upright, then explore the allowed transforms which may lead you to a factored state in 2 dimensions, from the lowest digit of the 2 odd integers both upright and upleft, its factors, and in the 2d space they are rectangle edges of, those pixels/digitbits must be on when there is an on bit somewhere downleft and downright after crossing empty cells, but if it finds either whole diagonal row empty then it must also be empty/zerodigit. The 2 main rules are: Any 2 cells below may both turn off and turn on the one above, or the reverse, and any on cell may move horizontally to an empty cell.

AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only 5 lines of code: Ten arithmetic and bitwise operations in all. It's called MOTE because a PRNG can't be made much smaller (or faster) without introducing bias or severely reducing avalanche. ...

...It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a 16384-bit key. The BEDBUG generator itself is a mere 5 lines of code: Three rotations; two pseudo-random lookups. The default BEDBUG configuration alternates the rotation constants unpredictably. ...

MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that...

Netmate is a GTK+ program that shows network protocols headers in 32-bit aligned fields, identical as they are represented in Request for Comments (RFCs). It can be used to learn and teach about network protocols and to understand their functionality and collaboration.

YASP (Yet Another Simple Processor) is a 8-bit microprocessor with microcontroller capabilities (I/O ports, REQ, ACK) that can be used as a small computer for educational purposes. Its development environment includes simulators and assemblers.

...As you can see in my GPE documentation, I no longer use the friend keyword quite so liberally (In fact, haven't used it once in GPE). The naming convention I have used is a bit wonky as well. In addition the scoping for all the variables, methods, etc. really needs to be reorganized. I might get around to doing a refactoring on this code, but I wouldn't hold my breath. I wrote it over three years ago, and wrote it in quite a hurry when I did. If you compare this stuff with my GPE code, its like night and day. ...

Assembler for "Tuna", an educational 16-bit RISC VLIW machine used Spring 2007 in CSE 362M at Washington University in St. Louis.

This is a conversion-to-binary training game prototype. Random bits appear, and you must shoot them where they fit onto various bytes (given in octal, hex or even bit ops, decimal or Ascii). Shoot wrongly and you lose that byte, or get it right and win.

A simple operating system made for educational purposes. It will be a 32 bit multitasking open source operating system. Latest release covers interrupt handling, device drivers and shell service.

OpenTCP is a highly robust and portable implementation of the TCP/IP and Internet application-layer protocols intended for those who want to implement TCP/IP functionality in truly resource constrained environments (8/16-bit MCUs).
