  • > The hardware team at Jane Street designs FPGAs and ASICs that run some of the fastest trading systems in the world, and the day-to-day work is full of puzzles just like this one: staring at a sea of gates, timing reports, or waveforms and slowly teasing out what’s really going on.

    Although not really any more. AI is really good at debugging failing tests so I no longer have to spend hours - sometimes it was even days - staring at waves and instruction traces.

    Tbh that's one thing I won't miss.

  • Were AI models able to find the solution and easter eggs?

  • Every time I see a Jane Street puzzle of this like I wonder in which way you can improve your problem solving skills for these things and how to extrapolate patterns from other things. I have a gut feeling that this is not only just grinding puzzles, there has to be a way to improve this. Curious if people have some insights on this

  • The EE/IC Design part of me loves this for trying to build a community around what is typically a very opaque and secretive industry. The social justice / millenial part of me hates this for being funded by high frequency trading, of all things. What a colossal waste of resources.

  • I asked Claude to "fuzz the circuit" and, while it didn't work, it basically ended up going the Z3/SMT route and solving it in ~3 hours. This is after the writeups were already out, but still, as a software reverser, pretty wild. Writeup: https://www.babush.me/how-not-to-solve-jane-streets-asic-puz...
