I've always wondered - how can I as a non X engineer be sure that the code on GH is actually deployed on their servers?

  you can't, and it's 100% sure it's not this code running in prod
  • jjordan 1y ago
    100% huh? That's a bold statement with no supporting evidence.
    • Pxtl 1y ago
      Sounds like the right tone when discussing a Musk project.

      Already posted above: https://github.com/twitter/the-algorithm/blob/c54bec0d4e029fe34926ef3258a86ccacc0d0182/trust_and_safety_models/abusive/abusive_model.py#L18 https://github.com/twitter/the-algorithm/blob/c54bec0d4e029f... It's redacted.

      Claiming that there's no supporting evidence is a bold (and obviously false) claim when the code is 2 years old and heavily redacted.

  I don’t think that’s the point of open sourcing things, in general
  • openquery 1y ago
    I agree in general it isn't. But in this case Musk claimed that was the point of open-sourcing the algorithm. Transparency on what they are or are not suppressing.

      When Tesla "open sourced" their patents, they required companies taking them up on it to, not reciprocally, not copy their "designs". So you get access to their patents in exchange for vague restrictions broader than the patent or copyright system.

      Oh, I see. Well, purely on his claim:bs ratio, I'd too take than with a grain of salt :)

  How can you be sure that the machine code that was generated from your C source files actually match the behaviour encoded in them? https://www.cs.cmu.edu/~rdriley/487/papers/Thompson_1984_ReflectionsonTrustingTrust.pdf https://www.cs.cmu.edu/~rdriley/487/papers/Thompson_1984_Ref...

  It’s not. The last “algorithm” release was a random grab bag of code which existed in some of the Twitter repo that might have been tangentially related to recommendations/feed. Source: worked at Twitter in ML/recsys.

      Even if this is the actual production code at this very second, it won't match prod for long if they continue this pattern of only dropping an update every two years or so.

        edit: disregard, misinterpreted
        • wtfwhateven 1y ago
          because the person you replied to said they worked (past tense) at twitter, unlike you who says they [currently] work (present tense) at twitter why would they tell someone not working at twitter anymore to stop working at twitter? and how does that amount to "biased, hypocritical, one-way persecution"
    • majewsky 1y ago
      This does not contradict what GP said.
    • close04 1y ago
      Honest question. Would you even dare to say you work at Twitter and then spill the beans on some very public lie or misdirection? It’s trivial to match your writing style between your HN comments and your work emails to identify you. Musk is famously a very petty, bitter, and vindictive person with an easy to bruise ego. I don’t have any knowledge of the reality inside Twitter but I also have no reason to believe the company would be transparent given the many past controversies, or that any one employee would be able to look at this code which has obvious redactions and say “everything else is definitely 100% prod” and not exactly what GP suggested.
