Well, also Firefox is making an excessive number of calls to that slow system call compared to other browsers (Chrome, Edge).

Manifest V3 is a perfect example of "great idea but terrible execution". The ability to have extension pages be suspended when not in use is great. Improving (and having finer grained) permissions is great. It should have stopped

It's hard to give concrete examples because the problem is inherent to large, "real" codebases - toy examples can't really do it justice. That said, there are some general themes: - The lack of implicit magic in the lang

I built my own that does this :) Just working on improving the UX now... It has some cool features too, like not injecting anything into pages until you activate it (so no performance cost or risk of breaking sites) being less reliant on pe

This doesn't actually happen though. First, VS Code asks you if you trust the workspace, and only when you answer "yes" does it run rust-analyzer.

All of the new documentation is horribly laggy in Firefox and all of the code sections are broken (eg. the visible cursor position does not match the actual cursor position...) This is latest stable Firefox on a high spec Windows 10 laptop.

I think they're probably right about the AI-sharpening using specific knowledge about the moon... However, they are wrong about the detail being gone in the gaussian-blurred image. If they applied a perfect digital gaussian-blur, then

It doesn't really work like that: a second is a second anywhere in the universe, but time at different places in the universe doesn't progress at the same rate. ie. the issue is not with how we define the second. The issue is expe

Not sure what you're referring to? As far as I can tell the national grid operates on a 30 minute settlement period. > For each half hour, known as a Settlement Period, companies can trade up to 1 hour beforehand that time period is

Fake meat is still a form of deception; it's something that's not meat pretending to be meat. If lab grown meat gets good enough to be indistinguishable from "real" meat, then it would no longer be fake, it would just be

"Artificial" is not synonymous with "fake". "Fake" implies a level of deception.

You generally can't actually check the government databases directly, but you can still determine this. First, companies can catch most fraudulent documents simply by looking at the document (eg. are the fonts all correct, does the che

So the table lists "USB 40Gbps" as supporting an 8k display at 60hz, then "Thunderbolt 3" is listed as supporting that transfer speed, but not an 8k display at 60 hz? Which is it?

Another fun technique similar to hazard pointers is epoch-based memory reclamation (implemented here https://docs.rs/crossbeam-epoch/0.9.13/crossbeam_epoch/ ). One advantage of these kinds of "localised&

One neat thing here is that the compiler is aware of which types are `Copy` and not internally mutable (not contianing an `UnsafeCell`). For these types, passing `&T` and `T` are equivalent, so the compiler could just choose the faster

Not really. If you imagine a supply chain with raw materials at one end and finished products at the other, if every step along the chain is taxed even a small amount on their total revenue, the cumulative effect would completely dwarf the

Slightly ironic that Rust is criticized for having multiple string types, and yet the solution to simplify string handling in C is to introduce the exact same types (str_t == &str, strbuf_t == String) albeit without the safety guarantee

Because it's like cavemen pondering the safety of nuclear fusion after discovering fire. Yes: nuclear fusion could be dangerous. No: there is nothing useful that can come out of such "research". You know what would be useful

Yeah... Especially as it's not actually a JIT compiler (yet).

It's not backwards: you run the fuzzer, you look at the code coverage, and you compare that against what you expect to be tested. Then you update the fuzzing harness to allow it to find missing code paths. It's far more doable tha

by Diggsey 4y ago
Fuzz testing has a very high chance of detecting bugs, especially these kind, but you do need to at least check that the fuzzer is reaching the relevant code!

They're saying don't write such a parser in C. Use something else (memory safe language, parser generator, whatever).

It also has higher energy density. Which is important for some applications.

Yeah, arena allocators are a great tool, but they are not a magic bullet either. Also the author's condescension about automatic memory management is... telling. Remembering to call "free" is only one small part of why tools

Yeah a raw pointer makes sense but is equally unhelpful for the caller, since there's still no safe way to access the data. It sounds to me like the Python buffer protocol is under-specified, which can lead to data races in native code
