Apple already has excellent x86 emulation. But Apple has locked-down GPU with a proprietary API that adds another unnecessary translation layer where it hurts more.

Compilers inline everything they can. Partly it's due to lack of better ideas for effective inter-procedural analysis and specialization, but it could also be a symptom of working around the cost of ABIs.

It's even worse with The Matrix where nobody is even sure any more how it was supposed to look, except definitely not as green as the DVD release. Noodle made a charming video about going mad researching this: https://www.yo

If you're a junior now, and think your code is worth stealing, it's probably only a matter of time before you gain more experience, and instead feel sorry for everyone who copied your earlier code (please don't take it person

Fil-C uses `free()` to mark memory as no longer valid, so it is important to keep using manual memory management to let Fil-C catch UAF bugs (which are likely symptoms of logic bugs, so you'd want to catch them anyway). The whole point

Fil-C will crash on memory corruption too. In fact, its main advantage is crashing sooner . All the quick fixes for C that don't require code rewrites boil down to crashing. They don't make your C code less reliable, they just ma

It depends how much the C software is "done" vs being updated and extended. Some legacy projects need a rewrite/rearchitecting anyway (even well-written battle-tested code may stop meeting requirements simply due to the world

Lack of DC fast charging makes the range even more limiting. It takes 2.7 hours to add another 150 miles. Modern EVs can add 150 miles of range in 10-15 minutes.

Debian's tooling for packaging Cargo probably got better, so this isn't as daunting as it used to be. Another likely thing is understanding that the unit of "package" is different in Rust/Cargo than traditionally in

You don't really need 8K for gaming, but upscaling and frame generation have made game rendering resolution and display resolution almost independent.

Extra "wasted" capacity has many benefits for EV battery packs. It allows distributing load across more cells. It allows using cells with a lower C-rating, which typically have better energy density, and longer lifespan. Distribut

The code needs to pass integrity checks of the safe Rust subset, which is a different challenge than writing dangerous code without feedback.

Nothing in the C standard requires bytes to have 8 bits either. There's a massive gap between what C allows, and what real C codebases can tolerate. In practice, you don't have room to store lengths along pointers without disturbi

Note that Fil-C is a garbage-collected language that is significantly slower than C. It's not a target for writing new code (you'd be better off with C# or golang), but something like sandboxing with WASM, except that Fil-C crashe

You seem to think of "rust enthusiasts" as some organized group with a goal of writing Rust for the sake of it. Rust is long past such extremely early adopter phase. What you're seeing now is developers who are interested in

That's non-sequitur. The problem here is that C is too basic, dated, with inadequate higher-level abstractions, which makes writing robust and secure software extra difficult and laborious. "Learning underlying hardware" does

It's not a single return type T that is a sum type. It's two control flow paths returning one type each, and that's a major difference, because the types and control flow are complected together in a way that poorly interacts

Either is another name for a Result type. Either works, but now you have two ways of returning errors, and they aren't even mutually exclusive (Either-retuning function can still throw). Catch-and-wrap doesn't compose in generic c

You've discarded the error type, which trivialised the example. Rust's error propagation keeps the error value (or converts it to the target type). The difference is that Result is a value, which can be stored and operated on lik

It would be a waste of effort to adopt Liquid Glass now. Even Apple hasn't figured it out yet. The new UI breaks existing conventions, and isn't even self-consistent. You're not helping users by jumping into that chaos.

Advancements in lighting can help all games, not just AAA ones. For example, Tiny Glade and Teardown have ray traced global illumination, which makes them look great with their own art style, rather than expensive hyper-realism. But current

It's also a communication problem, because labels like "100-year/1000-year event" are easily misunderstood. * they're derived from an estimated probability of the event (independently) happening each year. It does

reserve() reallocates by at least doubling the capacity. reserve_exact() reallocates by exactly what you ask for. If you reserve() space for 1 more element a 1000 times, you will get ~30 reallocations, not 1000. This inexact nature is usefu
