The three workers wading through water to open the sluice gates did indeed happen, but it's worth noting that all of them survived just fine and at least two were still alive as recently as a few years ago. I agree, though, I love how

It varies. The physics part is oversimplified and, at times, overdramatized (the threat of a megaton-range explosion being a particularly egregious example). The range of characters is highly limited by the format of the series (hence the f

Thank you, I didn't know about this! Currently still on 5.0 for most of my machines, but this will be helpful once I move to 5.2+.

The volatile keyword will certainly lead to implications for cache coherency, but it cannot bypass the TLB or somehow magically avoid the need to involve the memory controller. Unless I'm grossly misunderstanding something, a majority

I don't understand these slides. The volatile keyword does not magically bypass the mechanism by which modern CPUs write to main memory. Am I missing something, or are they somehow meant to be ironic?

The conversation was about the (nominally technical as well as more mainstream) press, not the experts. My remark regarding "wild hysteria" was made in that context. Experts and competent users will do the same thing they always d

He isn't so much making an argument as stating a simple and fairly trivial observation. It's rather sad that hysterical alarmism has grown to such proportions as to even necessitate such observations. My only objection to his thes

I'm glad the PC enthusiast space hasn't succumbed to the wild hysteria caused elsewhere by the side channel issues. It's tiresome to see every new variation people come up with reported as a new apocalypse all over again. Hal

Sure. It's a correct implementation of the projection method [1] for solving the 2D incompressible Navier-Stokes equations, so it is in fact using genuine physics. In terms of physical accuracy, there are some caveats - it's using

Because of everything you've outlined in your last paragraph and more, I don't know many competent C++ programmers who would call std::string or std::map "zero cost abstractions" with a straight face. That term is more c

Taking into account close calls is a fine idea, but they have to weighed by not merely how close to disaster they actually came but also by the magnitude of the potential consequences. Very few (but not zero, granted) of the known close cal

"Safe" is a relative term. Chernobyl is the worst disaster in nuclear history by a huge margin and killed between 200 (the uncontroversial short term deaths) and 4000 (according to the most pessimistic cancer attribution methodolo

Why do you equate comedy production with obnoxious shouting in public? It doesn't even make sense as a strawman. I don't produce comedies because I'm not a filmmaker. I don't shout random insulting things in public becau

I'm not sure what it is that you're arguing against, where did I advocate shouting abuse outside a school as a productive way of doing anything? Perhaps you could clarify your argument somewhat. Civil debates are great, I'm h

Why does the no heap requirement preclude C++? Obviously, you couldn't use much of the STL (not really a loss in constrained environments), but I don't see a reason to write off the language itself?

Well, there are two at least partly orthogonal points here - the teleological discussion over what computer programming actually is and the practical point regarding which mindset is more likely to lead to better software. I don't know

That's exactly right, thank you. It's a fundamentally simple point often made by embedded and game programmers (perhaps most famously in recent years in Mike Acton's keynote at CppCon [1]), but most programmers seem to have c
