    Can't tell if sarcasm...? What I mean is that the globe should rotate towards the East, not towards the West. This is of course assuming a stationary camera!

    on that note, are you aware that the globe on stripe.com is rotating in the wrong direction?

    So cool to see you guys go from strength to strength since the old days in our EF cohort! Onwards and upwards!

    From the article: Where does the money go? The penalty is divided up between the other European data authorities, while the money that comes to the ICO goes directly to the Treasur…

    That's really cool! I checked Rigetti's github but there seem to be no open source Julia projects there (although, somewhat surprisingly, lots of Common Lisp!). Are you free to say…

    FWIW, it's exactly what I've heard when talking to Uber drivers in London. One guy used to work as a minicab driver; he prefers Uber because he can choose his hours, doesn't get cu…

    It may have been the "literally scared for our lives" part.

    There's deeplearningbook.org, which starts with the basic maths and then goes into considerable detail on cutting edge work.

    (EU national in London) Not at all. I think the doomsday threats are overblown and the negotiating parties will reach a mutually beneficial deal at the 11th hour. Much more concern…

    I do something similar, here's my Makefile -- I have scripts that build figures in a separate directory, /figures. I'm sure it could be terser, but it does the job for me. texfiles…

    Honest question, how is this different from what you can do in e.g. python? The python interpreter supports reloading of modules and evaluation of expressions, is there functionali…

    Isn't it true though that there would be an O(n^2)-type difficulty in adding extra qubits, since they all need to interact? Or is that an oversimplified view?

    Yes, according to the first law of Thermodynamics, energy is conserved; regardless of whether there is computation being done, 100W of electric power will result in 100W of heat be…

    They trained on a computer model of the optical circuit, and only did the feed-forward step on the real thing. The rationale for that is that real-life models spend much more time …

    Well, yes and no. You are absolutely right that a complete implementation of TeX would be difficult, but you could read a subset of the language that is big enough to be useful, in…

    Not entirely what you're describing, but pandoc goes a long way towards being a sort of LLVM for text documents. In order to do all the format conversions, it transforms inputs int…

    yes, it would be really helpful to get some examples of the counterproductive advice.

    The counterargument is that as more and more industries start to do their engineering at the nanoscale (whether coming from above, as in materials and electronics, or from below as…

    There is the fact that proteins are constrained to function as part of organisms that are capable of self-replication. This constraint means that proteins (mostly) are not very sta…

    I don't know if this is what you're referring to, but a common application for government-owned supercomputers is simulating the degredation of nuclear warheads. The degradation of…

    You could compare raw FLOPS (Floating point operations per second) but that would only tell part of the story. These supercomputers are highly engineered for low network latency be…

    Hi Christian, great to have you replying directly like this; I hope my criticism came across as constructive, since I'm super excited about and impressed with this work, as someone…

    Super interesting. If you read the Feynman speech that he references at the beginning, he actually mentions that as you scale machines down, things like mechanical rigidity will de…

    They fund individuals for a fixed, three month period, during which you are free to work on whatever and with whomever you want. After three months, they invest £10000 (in exchange…

    It's completely the latter. (disclaimer: also in the current cohort)
