  • The E2 drives are 200 millimeters (7.9 inches) in length, measuring 76 mm (3 inches) in height, and just 9.5 mm thick (0.4 inches).

    So two of them would be roughly the size of a dual fan GPU. I can definitely see how it would make sense for servers. With that heigh it should just fit in 2U. And then you can probably fit like 30 of them side by side, or more, depending on how much space you need in between for cooling.

    In that physical footprint of the E2 drives you could roughly fit 18 M.2 SSD (2280), but they would still have to be 55 TB each to reach the 1 PB headline, or 16.6 TB each to reach the level of their 300 TB prototype. I think the max you get at the moment would be 8 TB for a 2280 form factor, so they still have pretty good density on their prototype.


  • Since the others tackled polygraph’s uselessness, I want to comment on another angle:

    I think fundamentally in such a case it will be easy for you to convince yourself that you’re telling the truth in the moment you say it.

    After all you are telling the truth to a version of the question, and you only have an assumption that the questioner means a different version of the question. Even if it’s a good assumption, nothing in particular makes your version worse, in fact you could argue it’s better.

    That combined should make it easy to mentally gloss over the contradiction. So I think your physiological reaction will be indistinguishable from telling the truth on control questions.



  • Okay that’s fair. I fricked around with some C++ numerics BLAS header library (I think it was Eigen) on Linux before that was complicated and annoying too. The ARM Fast Models simulator was also a pain. Maybe I just don’t like C++ development now that I think about it.

    C mostly worked okay for me though. And I agree Rust tooling is nice, but admittedly I have not really worked on a big project in it.
