Isn't because in Cars the character itself is the IP, not the actor? For example, if Owen Wilson started cosplaying as the Cars character and making money out of it, he could be sued. Reminds me of an Archer bit: https://yo

I didn't know browser vendors supported WASI! I said that as some of us do not use WASI at all, just WebAssembly itself, so they can save some time by not reading this if they're not interested in WASI and/or its limitations.

by fathyb 2y ago
I agree, my personal take: if you don't want to get your hands dirty, WebAssembly is not ready for you yet. It'll take at least 5 more years before the tooling gets into a state where things should just work (especially DWARF supp

It really depends on what you're using. If you use Rust with `wasm32-unknown-unknown`, you'll likely get small binaries (<200 kB). If you use C++ and Emscripten with all features enabled, then yeah you'll have multiple meg

An allocator is free to only `mmap` addresses that are within a range. I think jemalloc could allow you to do that using custom arenas.

If this was intentional, shouldn't it also affect `mach_absolute_time` which is used by the standard libraries of most languages and accessible to Swift? Also note you can get precise JavaScript measurements (and threading, eg. using p

I believe `CACurrentMediaTime` depends on `QuartzCore.framework` and `Date` is not monotonic. I would also find it confusing if I found code doing something like network retries using `CACurrentMediaTime`.

`Box<[u8]>` stores the pointer and its length (2 x size_t), `std::unique_ptr<const uint8_t[]>` only stores the pointer. That's for slices, for dynamically sized types (eg. `Box<dyn ToString>`) it contains a pointer to

by fathyb 2y ago
Another reason it is not true: Rust has fat pointers, eg. `std::unique_ptr<const uint8[]>` and `Box<[u8]>` both contain the same allocation data, but `Box` will be 128-bit on 64-bit systems.

I think that's where you're confused: `Arc` does not do any synchronization, again it's pretty much the same as `std::shared_ptr` (hence the name Arc: Atomically Reference Counted). Your `Locker` does not do what `Arc` does,

What is worrying is what it’ll mean for the access to the West Bank and Gaza, as they’re currently the only international media outlet on the field, and are documenting various atrocities that are currently being looked at by the ICJ.

Both are true, Rust just has more restrictions. It’s not completely equivalent, but you can think of `Arc<T>` as `std::shared_ptr<const T>` as in if you use `unsafe` or `const_cast` you can bypass mutability restrictions. Otherw

Rust `Box` = C++ `std::unique_ptr`, both have the same ABI (just pointers) Rust `Arc` = C++ `std::shared_ptr` Rust `Rc` = C++ `std::shared_ptr` but using a simple integer instead of an atomic so it is not thread safe `Arc` and `Rc` do not a
