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 Treasury.
So it seems most of it will go to other European data authorities.

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 what Julia is being used for at Rigetti (and Intel), and whether there are any plans to release things as open source in the future?

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 cut out of lucrative jobs to the benefit of the company owner's nephew, and feels safer at night due to the rating system.

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 concerned about the possibility of the current Labour party gaining power actually.

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.

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 functionality that CL has above and beyond this that makes it more powerful?

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 being dissipated.

About heating with computers, There is a Dutch company doing this, https://cloud.nerdalize.com/. It's interesting to think about how their economics work, because the heaters will be switched off for large parts of the year, and for much of the day. They must be banking that computation won't get much cheaper over time (in terms of FLOPS/$) because otherwise it'd be hard to recoup their initial investment. In a sense, this almost looks like a bet against Moore's law!

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 (and energy) in inference mode, so that is the step you'd most want to optimize.

I can't help but think it would be really cool to automatically produce a circuit that would output the gradient of the error of the actual NN, so you could optimize that directly.

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, including simple macro definitions and commonly used commands, which is exactly what pandoc's LaTeX reader already does.
