I agree it’s hard to believe it could be faster. But we expect there must be _some_ cut off where more registers is worse, it’s just a question of where. But more-than-one being usually worse seems surprising to me too. I expect it’s unlike

My mental model comparison says that the cost of those may potentially be about the same, with no clear winner over many benchmarks. I’ve even seen recently a claim that using two registers was measured to be slower than stack memory return

Do you own a house? Those come with non-trivial continuing expenses and time investment to maintain (or more expenses to have someone else manage the work.) I assume a mansion would only scale up in expenses from there. Plus taxes go up too

Nope, the bugfix is only $50. The other $49950 is for knowing which line to change. (adapted from old joke from https://allthetropes.fandom.com/wiki/Percussive_Maintenance ) And in practice, it also "buys" you

I wonder if you could scale it so that the goal behaviors were also a market equilibrium. So no complicated prohibitions for going public, but each additional report (aided easily by going public) would cut into your own earnings some perce

We got approximately the same numbers (your clock speed is likely to be much higher). User/system time is quasi-bogus, since it’s a high core count system (although still a bit concerning). I accounted for possible cache effect by runn

I helped work on getting that number from ~400ms to ~150ms maybe 18 month ago for the v1.0 release. FWIW, a big part of it was shedding a couple excess C libraries with bad load times (usually now lazy loading them when required instead). T

It says something like "without interference, some execution path has proven to be as fast as x". This probably isn't exactly what you wanted to know (e.g. expected time), but is likely to be much faster to compute for some t

Isn’t part of the problem here copyright, so Congress would need to make it legal? I thought that’s what killed the Google Books effort anyways. That said, I thought the Internet Archive is still engaged in an ambitious project to scan many

I don’t think that’s really contradictory though. I’ve lived through many cases of the sprinklers being set off accidentally (frozen pipe burst, rc-helicopter blade impact, and idiots using it as a clothes hook) and “some water” isn’t the p

Isn’t that 5% inflation over 5 years? Seems high as that’s about double the US target, but within reason assuming some confirmation bias (increase price gap and reduce duration) and other market lag.

I was trying to find a year on it and couldn’t, but agree it seems newer. FWIW, it’s not required to be able to run any setup code in the child to do arbitrary setup. For instance, WinNT makes that very hard, but has a larger syscall interf

Mainly only the address space is copied, other resources usually become shared, except threads (which don’t get resumed in the child).

That's probably a tricky question, since CPython is also essentially the spec. PyPy talks a bit about this: http://doc.pypy.org/en/latest/cpython_differences.html#diffe... That's true, since Python has r

Excitingly, we soon may be able to have both (if you can compile your C code with a C++ compiler). Coroutines are in the working draft for the C++20 spec, so they may soon be provided by the runtime (and thus integrate into all of the other

Not exactly a systems language, but Python has deterministic destruction (due to the use of reference counting) of non-cyclic data structures. Edit: Oh, and if you don’t think that’s enough, note that Rust doesn’t guarantee destruction to e

I think you're trying to imply this is bad, but for a happier angle on it, let's add to the list of things we're using up: time. We have a giant sun that's only going to be here once. Don't waste the finite time tha

Is it though (a good sandbox, I mean)? A modern OS already tries very hard to be a sandbox that can run anything. What does Wasm bring to the table for iOS? I also feel like this is just a weird year for software, because we've got Was

Did you do each of these after a clean reboot, or are we looking at possible caching effects from the kernel? If any part was in cache, then we might be just comparing shared memory against IPC, and that's an obvious performance win, b

Probably true, but there is in fact the apropos readdir function, which does have a readdir_r variant to address thread safety issues (now apparently deprecated due to other unrelated design issues). So it seems the joke’s on us. Getting AP

Is it required that “rise” and “fall” be boolean/digital operations? I think it would be more reasonable to characterize them as analog/continuous. That could then lead to infinite variations in rates, even just with a single char

I’ve found that I could wear a bandanna under my helmet to cover my ears (and absorb sweat or keep warm, depending on the season), and significantly reduce the wind noise—specifically so I could listen to audiobooks more comfortably.

The article states that this matter is at “temperatures of around 1 million degrees Celsius”. This seems incredible, if true. Is my expectation of how temperature works in a near-vacuum simply flawed? Google seems to say the average tempera

But the copy only has to move n items, but was constructed with m items, where n < m (and usually n << m). Where n is the max size of the queue and m is the total number of items that will ever be enqueued. On the other hand, an ar

Only if you eagerly shift all elements on every operation. If you allocate extra space, and only shift every N operations (N being the max size of the list), it’s O(n/n), eg O(1) amortized. As mentioned already, you can represent it as
