  His 'second jury' were comical. "Most were surprised by how little he had taken in relation to the whole: eight megabytes in a platform that consisted of an estimated one gigabyte of code. " Really? One gigabyte of code? Or one gigabyte of third party binaries, precompiled libraries, documentation etc.? All you need are the source files, and those language keywords compress nicely. Exactly how much plain text do you think they have? ' "But that’s the secret sauce, if there is one,” said the juror. “If you’re going to take something, take the strats.” ' Rubbish. The strats are the easy (or at least easier) bit in the high frequency space. That's like taking a dump of the html from facebook/twitter and thinking you've stolen their site. It's the scalable, distributed infrastructure that drives large websites, and it's the fastest possible infrastructure that drives HFT. One thing Lewis got right is the Coke/Pepsi analogy, and it really is that simple. A straight up race. " “It’s way easier to start from scratch.” " It is, and it isn't. In even the worst codebase there will be nuggets of usefulness that will accelerate the process. Isolated parts of the system that you've perfected. Exchange message decoders for example (ITCH, FIX/FAST, etc.). This is especially true when you, the genius who will be starting from scratch, has worked on it for a few years. I assume he was doing something useful in his time at Goldman. I'm not buying the innocent act.

    Aren't these problems the jury faced or measured incorrectly rather than inaccuracies in the article itself?

      And? How does that make it any less useful to have the existing code as a guide?

        I don't know...having the existing code available seems like it would be more useful for the "strat" stuff than for the infrastructure, if you posit that it's all going to be rewritten from scratch in a different language. But I don't know shit about trading, so maybe I'm wrong.
