Not a problem, if your interest lies in using them instead of storing them.

Basing on how much it is important to understand categories to know mathematics or to know other languages, I would say nothing. But probably it can be fun, and definitely you can then brag about it. However, if you still have to learn X, d

It is not the only problem, unfortunately. For example, there is no way to specify the order of quantifiers, which is very important (if you commute existiential and universal quantifiers, in general you change the meaning of a formula). So

I am not British nor familiar with British politics. Is there any article that tries to explain the reasons behind what happened? Labours were something like 20% behind when the vote was called, but went close to winning yesterday.

By the same logic, every one in the world who could have bought one kBTC when it was cheap but did not (i.e., more or less every single human in the world) has thrown away $4.8M. Even the OP wasted much more than $4.8M, because they might h

It is very implausible. A sandbox detection algorithm has a lot of different options on what to observe to decide whether it is running in a "genuine" environment or in an "artificial" one. You probably have to see what

The comparison with press does not fully stand. After the invention of printing lots of different publishers were born, while we still have essentially just one Google. So they actually have quite a strong monopoly and quite some power with

I wonder how can anyone expect Bitcoin to become popular, if things keep being that unstable...

There are no physicists' observations here, as I get it, it is all theoretical work, which is essentially mathematics. It is not rigorous mathematics, otherwise we would actually have a proof, but just a proposed reasoning that in time

Usually spacecrafts like that are built in clean rooms and care is taken so they are sterilized when sent to space. I have no specific answer, though.

This is not about computational thinking. This is about Wolfram advertising.

My first guess was that for most fonts the glyph "B" has splines, while "#" does not (only segments) and in line of principle rendering splines is more expensive than rendering segments. But probably this is nowhere that

On the specific issue of the carbon budget, there is a point I miss: what do we count in the carbon dioxide emission by agriculture and livestock? In both cases carbon emitted to the atmosphere is just carbon that was earlier fixated from t

BTW, by GPG I actually meant OpenPGP. The tool itself may have shortcomings, but everyone is welcome to write another one that uses the same standard and works better.

Please correct me if I am wrong, but as I understand it in GPG's case perfect forward secrecy simply cannot be used. PFS can be used in frameworks where the two parties interact and can use DH or similar protocols to establish an ephem

My navigation application supports rotating the map with double touch. You can put it whatever-you-want-up. This is probably rather common in other applications. You might then be a bit confused if you have to look a conventional north-up m

Correct. ZF is anything but realistic. It is just nice for creating mathematical theories, which can indeed be wonderful and also very useful for our world.

Nice, although it would be nice to have an idea of the proofs behind.

It always impress me how much it is difficult to track things in space, so that still in 2016 we may not have an idea of what is happening up there...

The argument is mostly about double comparisons, i.e., checking for belonging to an interval.
