Sounds like a cool sci-fi idea, but you would probably need to put a significant amount of material 1,500,000km away to put a shade over the Sun. Probably comparable to the mass of our atmosphere. And then repeat every decade.

For me the most important defining characteristic of a framework is inversion of control. With a framework high level control flow is dictated by the framework itself. It follows from this that using two different frameworks can be challeng

by planede 4y ago
Yeah, but this has other trade-offs than the other two options of just using a 3rd party framework and inventing your own. Not saying that this is not viable though.

Submissions for the Hutter price also include the size of the compressor in the "total size". So I assume that's hard to beat if you use huge neural networks on the compression size, even if decompression is fast enough.

the `read -r foo < configfile` might be obscure, but every line in a POSIX text file ought to have a newline terminator. If this is worth erroring out on probably depends on context.

[]{}() was always valid, but you can drop the arguments in more cases in C++23.

The difference here is that the behavior would need to be documented. That's why I didn't bother with "the behavior of the program is unspecifed", because that really is just undefined behavior. But yeah, actually listin

You are right, but OP asserted that IB (implementation defined behavior) would be needed for this. IB would also allow this, but it is not necessary. All of undefined/unspecified/implementation-defined allows this. edit: Whether u

Unspecified behavior and implementation defined behavior are distinct in theory. The latter requires the behavior to be documented by the implementer, while the former does not. In practice I dare you to find compiler documentation for each

vector is a template, at most vector<some_type>::operator[] will be a weak symbol, and I bet it's inlined from -O1 and above.

Good news, in C++20 you can add <> there somewhere, although probably it can't be empty. Anyway, probably obscure enough: int main() { []<class=void>(){}(); }

UB does not prevent that. Compilers already have flags for those, for example gcc's -ftrapv and -fwrapv .

I have an autossh + tmux setup. It's along the lines of autossh -M 0 -t remote "tmux new-session -A -D -s $RANDOM$RANDOM$RANDOM$RANDOM" with appropriate ServerAliveInterval and ServerAliveCountMax settings. It works so

What's the typical circuit found in a laptop or phone? They all have to deal with this stuff internally. IMO a cheapo x64 laptop is better than a raspberry PI + some jerry-rigged UPS setup for a low-power home server setup, YMMV.

IMO the arrows point to the right direction, in a sense that in my mental model arrows are typically owned by the pointer, not the pointee. The pointees are typically unaware of what points to them. A base class "doesn't know&quot

I think most importantly your opponents become less likely to knock your number out. The goal is your number to win, not your opponents to lose.

If we discovered them, I don't know. But if they discovered us then they probably use 0-based arrays.

You will, your opponents will choose matching numbers 28% of the time if they use the Nash-equilibrium mixed strategy.

Got the closed-form solution: P_i = a^i (1/a - 1) where a is the real-valued solution of a^3 + a^2 + a - 1 = 0 . a = 1/3 (-1 - 2/(17 + 3 sqrt(33))^(1/3) + (17 + 3 sqrt(33))^(1/3)) edit: The probability to win comes

> unknown non-optimal strategy The hard part is to establish a prior for this "unknown". Otherwise you can't say anything.

What's super surprising if that I'm "dumb" and I play against two "smart" players then I can't have a bad strategy. Assuming that the "smart" players play the Nash-equilibrium mixed strategy then

I feel that it's actually the opposite. There is a world of difference between 0.0...01 and 0.0...001 , where ... represents the same number of 0s in the two cases. Same applies for the other end. edit: Do I really want more resolution

For what it's worth you can define main as auto main() -> int { ... } in actual C++, which is not very far off.

IMO differentiating a specification and reference this way is just nitpicking. However it looks like that at least unsafe rust is underspecified regarding aliasing rules, therefore a bunch of unsafe rust is undefined behavior by definition.

Instead of speculating whether something like this could or could not be true, there should be a way to test it scientifically. * Have pairs of mobile devices set up from factory configuration with WhatsApp and Instagram installed. * Simula
