Czech/Slovak speaker here. Slovak kept the original sound /uo/, which is written as ô. There are many words with a simple ô/ů substitution, for example Czech “trůn” /tru:n/ vs. Slovak “trôn” /truon/, meaning “throne”.

So no, they are not phonetically equivalent, but they are related.

The rule to read the author list, simplified: first author did the work. Last author funded the research. Everyone else contributed somewhat.

I think this recent paper [1] sheds quite a bit of light on this.

I was surprised how easy it is to setup a time-machine-like backup with rsync. I'm backing up every hour to my server, and a cron job prunes the backups every night. Disarmingly simple.

How does this go with the often quoted mantra that you can only beat compilers today if you're an extremely skilled asm programmer? Or is the problem you describe just about executable size rather than speed?

What does “cease providing” mean? Don’t you have the software? Isn’t the whole point of a standalone program that once you have it, the company can just go bust?

Have a look at Qbserve.

Why the quotes around "Python implementation in JS"? Isn't it literally just that?

That this happens is of course difficult to disprove. My only defense is that very often, I read things from acclaimed people and think "bullshit". I don't have any particular reason to like what Alan Kay says besides having read previously things from him that I liked.

Also, in this particular case, my point wasn't really about the truth value of what he claims (which I'm not fit to judge), but about the clarity of how he claims it.

I'm always blown away by how crisply is Alan Kay able to put complex thoughts into words. I feel that the level of clarity I can achieve on the scale of a sentence or two he can achieve on the scale of several paragraphs.

But it's also very obvious that general relativity can only be an effective theory that fails for very strong fields. No one I know actually thinks there are singularities, those just point to places where GR starts to significantly deviate from reality. Navier–Stokes equations are very accurate on macroscopic scale, but regardless of their mathematical properties, there are no actual blow ups in real world, because ultimately, the liquid is composed from atoms. Likewise, the fields in GR must be ultimately quantized in some way, which will almost certainly break the singularities.

The infinities in QFT are really just a hack. I mean, all those calculations are perturbational in the first place, so they can be hardly considered a "true" picture of reality.

It's rather the degree to which Python is dynamic that makes it slow. PyPy could be considered an implicit JIT compiler for Python, yet it is still far slower than Julia. The level of magic you can apply to Python objects that the interpreter/compiler must support is just a different league than Julia. I'd be interested if someone could compare to JS.

I’d expect the conditioning to be subconscious. Doesn’t matter the computer is locked down. Your brain sees a computer, which triggers a multitasking, distraction-rich mode.

Vast majority of scientists is not able to write idiomatic Fortran, yet alone idiomatic C++. Scientific C++ code that didn't have an oversight from a professional C++ developer will be always horrible. Scientific Fortran code written without such oversight can sometimes be bearable. This is perhaps the main advantage of Fortran.

That all depends on factoring. If running your code once means evaluating some function hundred times, then that's no issue.

One-based indexing is not a semantic issue, it's a language-design decision you may disagree with.

Correct, but git doesn't recompute the hashes locally, so it wouldn't know they are wrong.

They actually use KaTeX [1], which is much faster than MathJax, supports server-side rendering, but supports a smaller subset of LaTeX than MathJax.

Yes, but not every black hole is surrounded by gas.

In general, physics does not work like this.

I've always told my parents who grew up in communist Czechoslovakia that the Chinese communism is a very different beast from the eastern-bloc communism they've know (which Vaclav Havel described masterfully in his texts). But this article would feel very familiar to them.

I think this may be actually the source of much confusion in discussions of how much "work" is good.

It also seems that he works at least partially on his own stuff. For me personally, there is a big difference between working on something for someone, and working on my own ideas. The latter tires me much less.

It is very likely to be a combination of innate predisposition and behavioral effects. Like almost all diseases that are not caused by external bodies, or extremely hereditary. So ADHD is not really a condition, rather, it is an axis on which you can fit somewhere. In extreme cases, I can imagine it's very hard to manage without pills. In most cases, one can probably work through it without pills.

First, the symmetry is not perfect with most snow flakes, if you look closely. Second, I guess there are asymmetric flakes, but they are probably rare. I’m sure though that no current model can explain the distribution of the degree of symmetry, perhaps not even an order-of-magnitude guess.

This is still an area of active research [1,2]. The basic hexagonal symmetry comes from the hexagonal lattice of bulk ice. What is more intriguing is the global symmetry between individual dendrites. From reading some recent papers, I think the mechanism is as follows. The snowflake is small enough that although the temperature and water pressure surrounding it can change quickly, all its dendrites are always exposed to almost identical conditions at a given time, leading to a largely deterministic growth, hence the symmetry.

DNS could always be used only for the initial name registration. After that, ownership would be managed within Keybase.

Potentially, they could still roll this out, because a dot, ".", is currently not an allowed character in a team name.

From the link: "On device revoke, the revoking device makes a new master key, encrypts for the private key for all remaining devices, and writes the new master key to the sigchain along with the statement revoking the old device."

Wouldn't it be more conclusive to look at what neuronal signals travel from the lower back to the brain, and how (if) they differ between chronic-pain patients and healthy people? Or do we miss technology to do that?
