I don't think this is true, though I think it's a common misconception. Undefined behavior is not meant to be an optimization tool. It's meant to be an anti-pessimization tool. In other words, it's meant to eliminate ov

UB is pretty damn fundamental to C. Not many people realize it though. It's the fundamental difference between C and C++ compared to Python or C# or Java or Rust or whatever.

Uhm, I'm pretty sure this page is wrong, and the compiler cannot optimize this out. An "indeterminate" value is either an unspecified value or a trap representation. Like they said, the value here cannot be a trap representat

That is completely irrelevant. The point is this is a reason to better regulate or ban digital currency, because it's massively helping the proliferation of ransomware. That people who get attacked by ransomware don't know how to

Very interesting! I feel like all the OS components are now written in DirectUI too. Did it turn out to be the way to go, or did it happen because it was shoved down everyone's throat?

That's good to know, I wasn't aware. But cash by mail... at what scale? How many people were attacked? And I don't see why the RSA analogy is "too harsh". Impractical is impractical.

by wfunction 9y ago
"It takes longer, but it's possible"? That's like saying decrypting RSA "takes longer, but it's possible". Yeah, good luck.

Regarding how awesome Bitcoin must be, can I just take a moment to point out that only half the reason crap like randomware exists (and hits places like hospitals, etc.) is suboptimal security. The other half is untraceable digital paymen

Yeah, I suppose if he's already decided for sure he doesn't want to, then this doesn't apply, good point. If the possibility is there though it seems a little dangerous not to try to save up for it. Worst case is you end up

Yes... I was trying to say, wouldn't it make more sense to work more right now so you can save for when you do have children. Because, like you said, you'll need the money more later than now, and you'll want to spend more

You're mixing lots of things up here. "It will dry out" has everything to do with the amount of heating and nothing to do with its evenness. Soups/sauces heat well despite uneven heating because of secondary effects li
