It's not clear to me if google is allowed to demand that non-google app phones not be called Android or if that would also be considered anti-competitive. If they must allow Androi…

As a matter of law, the EC may be right, but as a matter of user experience, the idea that the Android market suffers from not having enough OEM-installed software on devices is a …

But he did not purchase health insurance, he purchased travel insurance. It seems to me that the whole thing is "I bought travel insurance and I thought I would be getting global h…

> In reality, most claimants are going to spend much less than 1% of that £5 million limit before they get flown home. It only really applies to people who are at death's door and …

I never claimed it was in bad faith and I don't think it was. Considering incentives and conflicts of interest is perfectly normal and does not mean that someone is operating in ba…

The incentive to say so is pretty clear: if he flies away, not only does the doctor lose a 15,000 costumer, he can also be liable if anything does go wrong. Maybe he was indeed in …

To be sure, travel insurance is very often a very good idea. But it's travel insurance not "whole-world, any hospital, health insurance" (which I am sure you can buy, but not at th…

From his telling, the company was not very communicative when he contacted them, but, fundamentally, saying he should fly back to the UK for treatment and they'll cover the flight …

The reply in the uber blog is less "angry tweet" than "good peer review": it points to a very specific methodological weakness which has bearing on the final conclusions.

For some things, we do. But databases are not magical and setting up a good table/index system &c is also work and there is overhead. Thus, if we are talking about having (for exam…

`isin` is worse in terms of performance as it does linear iteration of the array. Reading in chunks is not bad (and you can just use `chunksize=...` as a parameter to `read_csv`), …

1. No, that function was the bottleneck, by far, and I can tell you that >10,000x was what we got between the initial version and the final one. 2. I don't care about faster at thi…

That is the _FAST_ version of the code (people keep saying "of course, it's slow", when it's the fast version). Here is an earlier version (intermediate speed): https://git.embl.de…

If I can fit the code into numpy-like structure, then Python is typically fine. The issue is when I cannot.

That may be the case. However, my point is that we started with a rather direct implementation of a formula in a paper. This was very easy to write but took hours on a test set (wh…

You are commenting on the variant of the code that is fast enough that it doesn't matter.

"spending an hour figuring out what arcane incantation I need to pass to np.einsum to get the operation I want" Yes, I have also had this experience and I hate how in the end, the …

I think this is part of my argument: as datasets grow faster than single-core CPU speed, performance matters more and more.
