Yep. It's not an async vs not async thing. The way some people talk about it, you'd think the async keyword was at fault. It's all about whether a function is callable in some context. Passing in the context as an argument or

Yeah. You aren't allowed to set up a life insurance policy on someone else's life, or a fire insurance policy on someone else's home. For obvious reasons. But buying an event contract that pays if someone dies or someone&#x27

No I'm just repeating what the original comment said, which is that it's explicitly UB: "5.1.2.4.1 says any volatile access - including just reading it - is a side effect. 6.5.1.2 says that unsequenced side effects on the sam

Why is that missing the point? Loading it twice, possibly with different values, is the intended behavior. It's only undefined because the C spec doesn't specify the order of the loads (unlike most other languages which have a per

Yeah, when naming your language, it's important to keep mind the expectations of people seeing headlines about articles about your language on blog aggregation sites :^) Now I'm thinking about "Smalltalk by Example" and

So true. I haven't checked out the CPU start9 is using (so please don't read this as an attack on them), but so much RISC-V hardware advertises itself as "open", but when you look up the SoC, it's only partially doc

Part of a larger pattern. If you're into travel blogs YouTube will serve you an endless barrage of videos with photoshopped thumbnails, exclusively containing fearmongering about whatever country or city they're visiting. This has

That can't be right. I'm reading this comment on an HDR monitor over DP right now. Don't all USB-C video outputs use DP alt mode too, with an HDMI adapter at the end? And they can do HDR.

Just like human typesetters who mucked around with silly metal cubes were replaced by more efficient word processing software, human writers who muck around with silly words will be replaced by AI. Future writers will work at a ~higher leve

I wouldn't say it's "to blame", but it is more susceptible to bad RNG. If the RNG is bad, you'll get more benefit from adding non-random bits than you would from additional badly RNG'd bits. The probability of

Great article! Love these types of deep dives into optimizations. Hope the project goal works out! I've felt before that compilers often don't put much effort into optimizing the "trivial" cases. Overly dramatic title fo

AFAIK Asahi development needs some hypervisor features for reverse engineering macOS drivers that only exist on M1-M3 and were removed on M4+. So yeah, it may be several years until they get support (or never, if nobody steps up to do it).

Is there any constant more misused in compsci than ieee epsilon? :) It's defined as the difference between 1.0 and the smallest number larger than 1.0. More usefully, it's the spacing between adjacent representable float numbers i

by hmry 6mo ago
Yeah I agree, that seems vey true. Although the average person probably also benefits more from learning about recursive descent and pratt parsing than LL(k) parser generators, automata, and finding first and follow sets :)

Sorry if I was unclear. My point was just that "if you were a victim, wouldn't you want this?" is not a very strong argument. What victims want does matter. But when it affects other people, their needs matter too. Especial

It's been a few years since I worked with the dragon book, but I think the most common complaint was that it starts with like 350 pages on parser theory: generating bottom-up and top-down parsers from context free grammars, optimizing

Privacy is not "convenience", I'm not sure how you arrive at that. And it's also not mine , it's everyone's. I don't want children to die (obviously). I also don't want governments to track the movem

Which points do you disagree with?

by hmry 6mo ago
1) If someone killed my child, I would probably want to kill them back. And yet we don't consider that sufficient reason to make revenge killing legal. The wishes of the victims need to be weighed against the cost it imposes on everyon

Two different meanings of "forever" there. An OS runs for an arbitrarily large finite time , which is different from an infinite time . Same way you can count to any finite integer with enough time, but you can never count to in

-O3 also makes build times longer (sometimes significantly), and occasionally the resulting program is actually slightly slower than -O2. IME -O3 should only be used if you have benchmarks that show -O3 actually produces a speedup for your
