You said > I think it should be preferred wherever it's an option for that reason most of all. And that’s far too broad in my opinion. Sure, if you’re writing in a language that makes memory management difficult, like C or Zig, that

This hasn’t been the finding of the R4L project. Go look at their code, it’s shockingly safe outside of the parts that interact with extern “C” symbols, which naturally need to be unsafe.

Just to note, Rust has had compile-time floats for a while now, but yes.

Floating point hardware on different CPU architectures don’t produce bitwise identical results, unfortunately. That’s the big issue. As far as I’m aware, they do produce semantically identical results, but something like the specific bit pa

It’s just much easier for an editor to manage a single interface for plugins over having to host a bunch of very large runtimes. Also, I doubt that you would have a very great time running both .NET and JVM in the same process. For one, bot

If this works for the programs you write, that’s great. It does preclude you from using many great data structures with potentially better performance - especially hash maps. Rehashing is pretty detrimental to most arena allocators you can

by simonask 7d ago
I respectfully disagree. The technique has its place, and I use it once in a while, but whether it makes a positive difference for performance is highly sensitive to a number of factors. For example, bump style allocators allocate very quic

by simonask 7d ago
Step zero of using arena allocation is to build realistic benchmarks so you can measure if it's worth the trouble in the first place. Standard allocators are incredibly good these days, and even plugging in mimalloc or jemalloc will be

> AAA games use allocators extensively They do, but not necessarily together with generic, standard containers. When you find yourself wanting a nonstandard allocator, you usually want it because you want it to have some interesting prop

I think this is a very reasonable question to ask. Language servers are certainly a significant source of slowdowns and editor unresponsiveness, and any time you're doing IPC, that's another source of latency and fragility. My cur

Thanks, now my brain will forever read it like that. I'm not even a little bit French.

Obviously, "slow" has very different meanings depending on context. Allocating a task object or interacting with the runtime in any way may be quite slow when you're in a tight inner loop, but it may be perfectly fast in the

It's not really like there's a budget for it, and "!" is already a type people have seen in the return position of extremely common macros (panic!, todo!, etc.), functions (std::process::exit, etc.), and expressions (ret

by simonask 13d ago
Well, one thing that every Rust programmer knows is the `panic!(...)` macro, and its return type is "!". That's why this compiles, even though not even match arm produces a value, which I think many Rust programmers are famil

Languages with effect systems typically let callers inherit the effects of their callees (e.g., calling an async function means the caller also is async), or force them to handle the effect (e.g., spawn the async call as a task and waiting

You’d just say “over 30” for that kind of temperature, or “almost 40” if it’s at the higher end. I think you’re taking your own unfamiliarity and just assuming that we’re all struggling because you don’t know how to translate what you’re us

The problem is that understanding everything from first principles is often the longest and least efficient road to learning the things that are actually useful. Psychoacoustics is interesting, but it's not something that really helps

by simonask 16d ago
Why would you assume that this particular turn of phrase would be common at all? People usually just say the temperature they’ve heard in the weather report, without giving a range. If you say “over 20”, people don’t assume “close to 30”, b

FYI, none of this has ever made any sense at all to somebody who didn’t grow up with Fahrenheit. Numbers don’t need to go roughly between 40 and 100, and then occasionally 212 and 450. The difference between 20 C and 20.5 C is not generally

33.3 cm is easy to measure out, and 99.9 cm is exactly 1 mm short of 1 meter, well within tolerances for carpentry. Narrower than the mark left by your pencil. But also like, we have calculators…

2 years is not a long time. What I’m telling you is that sentiments have changed dramatically, and every government and company board across the continent is taking actions to position itself according to those sentiments. You won’t see the

Hedging your country’s future on American presidential approval numbers is political suicide in Europe, as it rightly should be.

Also, what lip service, exactly? This is what I mean: Americans don’t understand the immense dividends they have enjoyed from being the defacto symbol of “progress” in the 20th and 21st centuries so far. American solutions were chosen by Eu

Perfect pitch is quite debated. What we know is that: 1) Most people with perfect pitch have it mostly on their main instrument, and they translate the pitch in their inner ear if they hear a different instrument, and 2) Many with perfect p

The tried and true approach is to find a piano teacher in your area, schedule weekly appointments, set aside at least one hour of practice every day between lessons.

My point is that it’s great to understand “why” Western music is the way it is, but it’s largely not the point of music theory. Music theory is useful because it establishes a vocabulary.

All of those systems you mention also include those so-called "pleasant" ratios.

I'm a programmer with a degree in musicology as well. This ain't it. I'm reading your comment with a certain disdain for analysis and theory, which I get - a lot of people come out scarred from music theory training, and I&#x
