Ah, don't worry, we have a concept of "onerous clause doctrine" to help with that. Of course, it's almost entirely up to a judge's discretion what is and is not onerous, so...

Ugh, troff. It's mind-boggling that the closest way to have an actual (hyper)link in a manpage is to use your pager's "search for text" function. No, "JuSt usE gNu iNfO it'S beTtER" is not an answer either

Could you give an outline of an example scenarios? For e.g. "print a line with a highlighted word in it" (alternative to print 'This is \e[7mhighlighted\e[m text\n'), and "print some text, move cursor to the second

Why, that's why you don't do genocide half-heartedly, you need to go all in, roll up your sleeves and really get down to work! Can't get a swarm of radicalized people if there is no people left to get radicalized.

Yeah, I too feel that storing the array's length glued to the array's data is not that good of an idea, it should be stored next to the pointer to the array aka in the array view. But the thrall of having to pass around only a sin

As I understand it, it's the other way around: for x86 (which is TSO) the fence doesn't really matter because the "normal" load is already slowed down, but for ARM it does matter quite a bit, see e.g. [0] (admittedly old

If by "more specialized hardware" you mean "everything that is not x86". Its main intended use is (was?) for chained loads and rcu_dereference(), where hardware does not require an explicit memory fence between loads lik

groans See, and that's why I'm personally fine with [[indeterminate]], etc: all of this is already a finely-splitted hairy mess and I'd rather not see even more keywords introduced if we can just use attributes instead. And

I wonder if you're fine with const, constexpr and volatile also being things. I mean, "const" really doesn't mean what one would naively think (that's what "constexpr" is actually for) and the semantics of

This is a decent reason, but your original comment is dangerously close to a completely strawman argument of "the argument of the func AverageAge(people []Person) should be called peopleToCalculateTheAverageOfTheirAges because what if

A good variable name is the one that is understood by reading it in context , which is why you don't have names like "current_person" or "CurrentIndexOfProductBeingUpdated".

The terminal-based editors like vim/emacs exist. Ideally they should work just as well the GUI-based editors, no matter what text files they're tasked to open and edit. As for the scripts, Unicode is slowly rounding up with the ac

Hmm. I'm fairly certain that most of that assembly code for saving/restoring registers can be replaced with setjmp/longjmp, and only control transfer itself would require actual assembly. But maybe not. That's the prob

Simon Tatham, author of Putty, has quite a detailed blog post [0] on using the C++20's coroutine system. And yep, it's a lot to do on your own, C++26 really ought to give us some pre-built templates/patterns/scaffolds.
