Welcome!

Hey! I'm João Marcos, a 24-year-old Rustacean from Brazil 🇧🇷.

Random stuff:

1. I have a blog.
2. I live with 8 cats.
3. If I'm coding then I'm certainly listening music.

Projects

CLI tools

Dotin	🦀	Easy and simple dotfiles manager. Inspired by, and compatible with, stow.
Ouch	🦀	Easiest tool for (de)compressing via CLI. Shipped to Arch, Brew, and more.
Dawctl	🦀	Mouse controller reverse-engineered from Razer's proprietary and closed-source software.
climsg	🦀	Message passing via CLI, messages and signals are broadcasted to multiple listeners.
pasoqa3	🦀	Parser And Summarizer Of Quake Arena 3 log files.
cargo-sweep	🦀	A cargo subcommand for cleaning artifacts, supports filters. (500k+ downloads)

Crates

fs-tree	🦀	Medium	Path Trie with an API focused on filesystem operations.
permissions	🦀	Small	Basic file permission checks. (60k+ downloads)

Experiments in building a programming language:

1. lox 🦀 - First hand-written Lexer, Parser, AST, and basic interpreter.
2. cocoa 🦀 - Experimenting with convenient Lexer and Parser libs, more interpreter experiments.
3. sushi 🦀 - Retrying Cocoa, but with good error reporting.
4. mini-c 🦀 - My first tiny LLVM-IR compiler! For a minuscule subset of C.

HTTP server experiments:

• Marquito 🦀 - An HTTP/1.1 server hand-written in Rust that handles 90k+ requests per second.
• balu 🦀 - A single-thread and blocking HTTP server API.

C

• projeto-itp - A non-SQL CLI-interactive relational database for a college project (Portuguese README).
• loadingnewyear - My first-ever project, draws a colored year progress in the terminal (lol).

C++

• icpc-training - Some of the advanced algorithms I studied for ICPC (programming contests).

Misc

• dotfiles - Personal dotfiles, managed with dotin (my own dotfiles manager).

Games I like

Some programming/engineering games:

1. Factorio (factory building)
2. Exapunks ("robot" scripting)
3. MHRD (build a computer)
4. Logic World (circuit building)
5. TIS-100 (very primitive assembly)
6. Shenzhen I/O (assembly)
7. The Signal State (program with modular synthesizers)

All of the above are Turing Complete, but if you really want to build a computer, go for MHRD or Logic World.

And, some non-engineering games:

1. Chants of Sennaar (translation and puzzles)
2. Hollow Knight
3. Outer Wilds
4. Sable
5. Dark Souls
6. Fallout: New Vegas (cool RPG)
