The main cash cow of Mathematica is the library, not necessarily the language. They could certainly make the language more open, while keeping the secret sauce in the library. They could also open up some core parts of the library too.

What kind of hidden allocations?

That is not really the same. `std::function` is a heavy-weight type-erased wrapper over callable types.

Problem is, function parameter names are optional, so you can already have something like `[](x){}`, where `x` is a type.

Good to know, I hope other toolchains catch up soon.

I know you are replying about "gov.uk" being clear or not, but I would just like to add that a FAQ would probably not cover an edge case.

C++ modules "exist." They exist in the standard, there are experimental implementation in compilers and there is little to no support yet from build systems (including cmake). I sincerely hope that it turns out OK, but it's n

You can create headers that are usable from C and C++, but you have to actively maintain it that way. As C headers tend to not have function definitions in them, it's fairly easy to avoid the C-only features. I doubt that Linux headers

There is no reason that Rust doesn't share the same infrastructure problems. The main difference is that the kernel maintainers want Rust in the kernel, while if you want to maintain a module written in C++ then you are on your own.

It's definitely not easy or even possible to enable from software. For all intents and purposes displays have three different light sources, with three different fixed spectrum. You can't block a narrow band from red and green pix

Now turn off your monitor! Do you see pure black, or maybe you see the reflection of your room and yourself? #000000 might not be pure black.

There are still some hidden gem features of search that are still there, like prefixing your search terms with site:example.com, or sometimes even better: -site:example.com .

Quoting still seems to work? As I remember + was always for emphasis/importance and quoting was for verbatim, but maybe I remember wrong. I get highlights for Robert here: https://www.google.com/search?q=bob+downey No

Interestingly that does compile in C++, which doesn't even have VLAs. A const int like that is usable as constant expressions: https://godbolt.org/z/PzsashEY4

It looks like that this solution corrects for dispersion in group velocity [1], but it's unclear that it can correct for dispersion in phase velocity at the same time [2]. My intuition that the latter is not possible this way, but opti

I just recently used raw disk images with qemu on Debian to remotely install an other distribution on an other partition and then I rebooted into it.

Yeah, because the "spiral-rule" is dumb, it's not a spiral at all. It's just regular operator precedence.

OK, I don't get `command`. When I run `command time -v sleep 10` it clearly runs /usr/bin/time on my system (the bash builtin doesn't have the -v option), but if I run `command -v time` it outputs `time`, correspond

Point being, it doesn't help you finding /usr/bin/command via regular search in PATH and it reports the builtin instead.

Apart from not being very random, it also wasn't thread-safe.

Most data structures in a project are not performance bottlenecks, so that's alright. While there are much better hash table implementations, std::unordered_map is still usable, although not great.

For C++ many standard library functions can't be implemented in standard C++. And it not only shows some very obvious compiler built-ins in the library, but the library can depend on behavior guaranteed by the compiler which is otherwi

I don't know how it works for C, but in C++ some (but not all!) fixes are recognized as "defects" in the standard and implementers are encouraged to implement the fixes in previous standard versions too.

My guess is that individual atoms entering and leaving the formation happens on a much faster timescale than the formation switching between quasi-stable states. It's almost as-if there are mini phase-transitions between formation size
