Oddly, mine is 100 too. I see a flat file with only 1995-grade HTML formatting.

There is no danger of C++20 modules failing to "gain traction". They are already in the Standard. All that is left is to define Standard module names for the Standard library components. Most likely that will be, simply, "imp

Except, all choose to. And, must, if they want to be compatible with code that all must compile.

Fortunately there is no need to standardize it. Everybody implements it, and all the same way.

The good news is that abandoning this "eternal vigilance" has no effect on compilation time, but speeds up development by the exact degree that you don't waste that time and attention anymore.

Every C++ compiler still in use will not even try to open a header-guarded or #pragma once file it has already seen. Anybody trying to optimize on top of that is engaged in foolish superstition. (If you are still using Sun's pre-St

This. For decades, Bloomberg development, and people so unfortunate as to follow them (because of silly book from the early '90s) adhered to an idiotic convention that wrapped every #include directive in an #ifdef block. Of course, all

I have a book by Bernd Heinrich, Mind of the Raven (1999), subtitled "Investigations and Adventures with Wolf-birds". He did research with ravens for years. I tried to find where he mentioned the behavior. One thing he noted thr

Then it is a good thing you have no say in our access to psychiatric pharmaceuticals. The only way known to distinguish one variety of depression from at least a half-dozen others is to see which medication relieves it. So, any RCT of a d

They can certainly be lost, anyway. "A strange game: the only way to win is not to play."

This follows the official line on who did what when, in ancient Egypt. A good series on YouTube channel Uncharted explores cracks in that line. IIRC Khafre, who gets credit for making the Sphinx, left a stela leaning on it boasting of his r

Not only, that, modern CPUs have transistors that switch in 0.1 ns. So even if they got to that speed, it would be 100,000x, not 1,000,000x. And, if they only got to switching in 10 femtoseconds, it would be 10,000x, not 1,000,000x. You mig

The article doesn't mention it, but ravens also act as spotters for wolf packs, leading them to prey.

Solar is by far the cheapest source of energy ever fielded, followed closely by wind. Nukes are among the most expensive still in common use. If you are hearing that nuke power is cheap, you are being lied to. Just now, nukes are about even

Yes. Car, cdr, and cons as the foundation of data structures turned out to be a bad idea nobody has retained.

I wonder whether cubits made of Bose-Einstein condensates would be more stable than what they are trying to make them out of now. It seems like decohering a collection of hundreds or thousands of atoms sharing a single state would take a lo

In modern C++, you get the same benefits as are claimed for "lifetime annotations" by operating at a higher level. In effect, a library may adopt responsibility for what the Rust compiler would have enforced, and where it matters,

Except apartment buildings in Siberia really are collapsing, for exactly the reason noted. We and they might wish they had foundations that didn't depend on the ground staying frozen, but that is not what is there.

Reports were that Energize customers were relieved when Lucid folded, because they would then not get a whole new set of compiler bugs to discover every quarter. They had, instead, the bugs they already knew about and had learned to work ar

I apologize for my impatience. The original description really could plausibly be read to suggest he did not even check for bad input, and just assumed input was OK, maybe with assertions that would run in debug builds. It is true that not

Of course I read it, back when. But people don't read books anymore, do they? Favorite recent book lately is by Don Eyles, "Sunburst and Luminary", about developing the Apollo lunar landing software. I bought it off the web

Yes. People are "only allowed to claim" to know about the merits of a language that they actually know. C++20 is the C++ to compare against, unless she wants to compare against, say, Rust as it was in 2014. C++98 is simply not an

The author does, in fact, bring up C++ herself. It is very strange to have dismissed it while knowing so little about its current status, and so worth bringing up. She didn't have to mention C++ at all. If you don't see C++20 as a

You can believe whatever you like, but the fact is that changes in C++11 and C++20 change the tradeoff between C++ and Rust in fundamental ways. The only way anyone could believe otherwise would be by knowing precious little about the topic

The author claims to know C++, but remarks suggest she has not learned much, if anything, of it since 1998. It is possible that her team is similarly not aware, so that it wouldn't matter if she was.

You might be curious about Kompute++. But anyway, the user-space stuff is still the same. This only affects the kernel modules.
