They don't explain what event-driven means, but AFAIK it's based on diffs between frames, which highlight motion and de-emphasise overall brightness/exposure: https://github.com/uzh-rpg/rpg_vid2e?tab=read

It's a shame it's just based on correlation with many additives/processes together, and individual contributing factors weren't singled out. The mechanically-separated pink sludge McNuggets may be ultra processed, but I&

If you're wondering why the paper seems to complicate "simple" constructs by converting them to control flow graphs — that's because many other kinds of static analysis, like tracking when variables are initialized and o

Almost every other principle in the charter can be used to shoot down changes for safety, so I'm afraid the safety part is only wishful thinking, hoping for a Sufficiently Smart Compiler/Analyzer to save them. The charter also cal

Imagine the savings in construction and maintenance costs if you could simplify the conveyor sections to be just two parallel iron rods.

This is a common and difficult problem when simulating fluids using particles. It's possible to simulate using a grid instead, and that computes pressure very precisely, but it has a downside of adding inaccurate viscosity. And there a

I'm surprised the simulation is run on the CPU! This problem has solutions that fit the GPU well, even for grid<>particle conversions.

UB is a guaranteed compilation error in constexpr. However, in regular code UB may only become known after multiple optimization passes (e.g. constant propagation, inlining). It's difficult for the optimizer to meaningfully err at that

LLMs are language models, and I think it's best not to try to extrapolate them to general intelligence. They are universal language translators, and a lossy database of a lot of text. They might be a component of some bigger AI system

This only handles a subset of bounds checks (spatial safety). It has nothing for temporal safety (UAFs), nothing for thread safety, nothing for uninitialized memory, and it doesn't fix C's defaults. This is very much a "we ha

With a caveat that when dithering in color, you need both: linear RGB for diffusion/color blending, and a perceptual color space for palette search. Distance in sRGB is more closely aligned with perception of color than linearized RGB.

I'd use popularity (how many people are using the crate indirectly) divided by trust level in the publisher of the crate. However, publishing a list that basically says "these are the least trustworthy Rust users" would cause

It could work for classifying honest/innocent differences. However, LLMs are incredibly naive, so they could be easily fooled by a malicious actor (probably as easy as adding a comment that this is definitely NOT a backdoor).

BTW, libjpeg turbo had been selected by JPEG (the group) as the reference implementation. There's no reason to entertain the old incompatible libjpeg fork. It didn't have any worthy compression improvements, and if you can use som

Open-source projects depend on their community and contributors, and community management is inherently political. No matter what "neutral" thing you do, some contributors will approve of that, and some will see it as a red flag.

It's basically an OS too. Application isolation, UI toolkit, 3D graphics APIs, storage, network stack. Netscape was right — browsers reduce the underlying OS to (a buggy set of) device drivers.

This makes sense, and explains why there's more Rust game engines than Rust games :) Rust adds friction to quick prototyping, but OTOH it is particularly good at providing robust, safe library APIs (with machine-checked memory manageme

The talk of a light frugal battery is only a marketing spin. The range and usable capacity are small, but the gross battery capacity is only 11% smaller than in Leaf. MX-30 is heavier than Leaf, Kona, and even Tesla Model 3 SR/RWD.

But this needs to be explicit, and doesn't undermine other statically-known lifetimes (pointers to the inner cell can't escape it). Just like statically typed languages have some dynamic dispatch features, but despite that still m

MX-30 is not particularly light, nor spacious compared to other "city" EVs. I get that Mazda has a reputable brand, but MX-30 is just an F.U. to the state of California. Mazda sells less than 10 of them per month. Not ten thousand

I think the point is that Rust encodes more rules in its interfaces (ownership, lifetimes, thread safety). If you misunderstand how a Rust library works, your code most likely won't compile instead of silently causing UB. The rules for

I think the "unknowable" lifetimes are C++'s own making. It's like types in statically vs dynamically typed languages. Types are unknowable at compile time when the compiler doesn't force them to be static. And si

You have to set some baseline. We assume the CPU can divide numbers correctly, even though not all of them did. Autoconf has set the baseline so low that everyone perpetually pays for the technical debt of ancient buggy platforms. Sometim
