Fuzziqer Software

In ages long past, I worked at Facebook as an intern. When I went to work for realz, I went to Quora, then Airtable, then Bidirectional Energy, and now Harmonic.

I write code for fun sometimes. Here's some stuff I made.

Slide: Roll the balls down the slope. The further down your ball goes, the more points you get! Try to get your ball stuck to block the other player's rolls!
Move Blocks and Eat Stuff (source): a puzzle game based on the ideas and mechanics of Supaplex. This project marks the first time I wrote a game and actually enjoyed playing it. It does not mark the first time I wrote a game without the code becoming a horrendous unreadable mess.
Treads: an arcade-style game. Push the blocks to squish the enemies! But watch out - the blocks bounce and can squish you too! Grab the powerups for a little help. And when something about a level looks different, something about the level behaves differently... strange things await!

Reverse-engineering projects
memwatch (source): a Mac OS process memory editor and search tool. memwatch is a powerful tool for cheating in video games, and works with any game that runs on a Mac.
gctools (source and releases): a set of programs for unpacking and disassembling various console video game file formats. Includes a synthesizer for JAudio BMS sequences, which works with music from Super Mario Sunshine, Pikmin, Luigi's Mansion, Mario Kart: Double Dash, and several other games. This synthesizer also works with SoundMusicSys sequences from classic Mac OS games, which can be extracted with resource_dasm.
resource_dasm (source and releases): a set of programs for unpacking classic Mac OS resources and disassembling applications. resource_dasm parses resource forks of any classic Mac OS application, and can even decompress resources that use their own custom compression schemes. The project also includes some tools for formats used in specific games, such as Realmz, Infotron, Dark Castle, SimCity 2000, Prince of Persia 2, and several others.
GameCube Action Replay Simulator and Control Simulator (GCARS-CS) (source archive) (download): implements Datel's Action Replay in a manner that's compatible with more games, and supports more code types. It also enables online play of some offline multiplayer games by synchronizing key variables across client consoles. This was the first attempt at unofficial online play on the GameCube, and the first to run on actual hardware. In the modern era, however, there are much better ways to play multiplayer GameCube games online via emulators. Here are some scripts that enable online play for a few games (USA versions): Capcom vs. SNK 2, F-Zero GX, Ikaruga, Sonic Adventure 2: Battle, Soul Calibur II, Super Monkey Ball 2, Super Smash Bros Melee v1.0.
Khyller: a free, private server for Sega's Phantasy Star Online. Supports PSO Episodes 1&2 for GameCube, PSO Blue Burst, and PSOv2 for PC, and supports lobbies (but not games) on PSO Episode 3. Don't use this server.
Aeon (old newserv): the successor to Khyller. This server uses a more robust architecture and is more stable. It's multithreaded, but has a broken locking implementation and is therefore unstable... but in my defense, I was 15 years old when I wrote this and had never taken any computer science classes at all. Don't use this server either.
newserv (source and releases): the successor to Aeon. This server is actually good. It's stable and doesn't have concurrency bugs like the previous projects, and implements a superset of both of the previous servers' functionality.

Network systems projects
cyclone (source): a timeseries database engine. A single cyclone instance does the jobs of all of the services that run on Graphite backend machines (carbon-cache, carbon-relay, and the webapp), and provides significantly better performance.
fastweb (source): a multithreaded libevent-based webserver designed for maximum speed. The page you're reading right now was served by fastweb. (Did you notice? Was it fast?)
redis-shatter (source): a sharding proxy for the Redis protocol. Unlike other similar projects like nutcracker, redis-shatter strives to implement as many commands as possible, to make a sharded Redis instance look as much like a standalone instance as possible.
sharedstructures (source): a library for storing data in shared-memory data structures. This is ideally used to store data that requires extremely fast access times, when the number of processes is large enough that keeping a copy in each process would be prohibitively expensive.

Language and compiler projects
nemesys (source): an experimental Python JIT (just-in-time) compiler. Compiles unmodified, unannotated Python to AMD64 assembly and runs it. Doesn't support enough of the language to be practically useful.
equinox (source): an interpreter and JIT compiler for esoteric programming languages. Currently supports Brainfuck, Befunge, and Malbolge.

Unclassified projects
zroot (source): a Julia set fractal generator. It can render still images or videos by producing a sequence of images, which can be piped to ffmpeg. Here's an example.
gb (source): a Nintendo Game Boy emulator. It plays Super Mario Land (without any audio), and not much else.
