  • Mixxx DJ Software

    2008 - present tags: sound open-source music

    Mixxx is Free and open source DJ software for Windows, Mac and Linux that gives you everything you need to perform live mixes.

    I got involved with this lovely open source project through Google Summer of Code in 2008. Since then I’ve contributed thousands of hours and quite a bit of code.

    In 2011, I took over as the project lead developer. Together with a handful of core developers and hundreds of contributors we work together to produce the best free DJ software available. You can check out our code on GitHub.

    As the lead developer I am involved with nearly every major change to Mixxx. Some of the major projects I’ve been heavily involved with over the years include:

    • OpenGL waveforms (my GSoC project)
    • SQLite-based music library
    • arbitrary numbers of decks (previously Mixxx was hard-coded to 2)
    • looping
    • hotcues
    • waveform scratching
    • sample decks
    • worker-thread based architecture for decoding audio
    • key detection and pitch shifting
    • dynamic / resizable UI (rewrite of the original skin system)
    • modular effects system (combined plugin-based and native effects)
    • non-constant beatgrids (allows mixing tracks that change tempo)
    • master sync (persistent syncing of decks)
    • concurrent library scanner
    • internationalization / translation support
    • tools for making evidence-based changes (performance metrics)
    • unit testing

    When I joined the project you couldn’t run Mixxx for more than a few minutes without encountering crashes. That’s what happens when you have thousands of lines of C++ written by 3 distinct teams of people over the course of a decade with close to no documentation!

    My biggest contribution to Mixxx has been restructuring the codebase to prevent common problems that lead to segfaults (i.e. reduction of mutable shared state across threads, separation of realtime callback code from the rest of Mixxx, modularity and good conservative code practices). Stability is a feature!

    I enjoy working on Mixxx because it combines my love of electronic music, software engineering and product design.

  • La Fontaine du Campus Est

    2007 - 2008 tags: sound music

    During IAP 2007, Rob Gens, Zack Anderson, and I worked building our very own Bellagio Fountain at MIT as part of the East Campus annual Bad Ideas competition. We weren’t able to finish it in time, and the project sat around for a year until the 2008 Bad Ideas competition, where we finally finished it up.

    It was a lot of fun and hard work to build, and we ended up getting help from other putzen. Check out the videos and get the source code here: La Fontaine.

  • The Basement

    2002 - 2007 tags: music

    I’m an electronic music fanatic, and I am fixated on most anything that glows. Around 2002 a group of my best friends and I started painting my parents’ basement with UV reactive paint. 5 years later, the room was completely covered with designs and murals. A sound system, comfy couches, and DJ equipment make this room a relaxing hangout for me and my friends.

    The website (another artifact of early-aughts web design — Java applet and all) has pictures, videos, and more information.
