Linear Zoetrope posted:There is but it's unstable, no idea how much of a PITA it is to use though. There's also an approved RFC for per-container allocators: https://github.com/rust-lang/rfcs/blob/master/text/1398-kinds-of-allocators.md It's not fully implemented yet but they're getting there.

Internet Janitor posted:perhaps the endpoint quoted the index because in a strongly-typed language on the other end it happens to be a 64-bit int, and if it were interpreted as a JS number it would parse as a double and lose precision? Twitters API legitimately has to encode Tweet IDs as strings because they exceeded 2^53 Tweets, so the IDs can no longer be represented as Javascript numbers

Pollyanna posted:I still don’t understand how 64-bit is somehow different between Javascript and anywhere else. Javascript doesn't have integers, all numbers are represented as 64-bit floats. Those can only store exact integers up to 53-bits long and silently become imprecise beyond that. code:

I don't get it, how is letting WASM modules call into Web APIs any more of a security/privacy nightmare than letting Javascript call into Web APIs.

Rust Playground allows you to import the most popular crates (which includes itertools) so you can easily peek at the disassembly on there https://play.rust-lang.org/?gist=95ac417519ad84d133ac7982bc496059&version=stable

VikingofRock posted:I couldn't figure out how to turn on LTO there, which is necessary to get itertools iterators to compile away. True, I don't think it's possible to enable LTO on the playground. Nightly Rust somehow manages to compile the iterators away without LTO though

AT&T syntax is a coding horror so it belongs in this thread  taqueso posted:Thanks! I just noticed the compiler understands the heap, it's completely eliding the heap allocated vector in the first two functions and just doing everything on the stack instead. That's seriously cool.

b0lt posted:The ability to replace operator new is required, and replacements are allowed to have side effects, so it has to emit the calls. But Clang does optimize operator new away in this simpler case 🤔 https://godbolt.org/g/B2DaNN edit: Turns out Clang does elide vectors if you build against LLVMs own stdlib implementation, that optimization just doesn't work with the default GNU stdlib for some reason. https://godbolt.org/g/rvCgG5 repiv fucked around with this message at 00:59 on Mar 10, 2018 |

A while back I discovered someone in our project had pulled in filter-object to, as the package name suggests, take an object and create a new object with some, but not all, of the keys of the original. Jesus christ, he published individual NPM packages for each of the ANSI colours. Is this guy for real.

Absurd Alhazred posted:Unrelated: Is this the right thread to laugh at this? The real horror is that anyone was treating OSX OpenGL as "supported" when it hasn't been updated for 8 years. This deprecation is just a formality, for all intents and purposes it was already deprecated.

JawnV6 posted:Having worked on the silicon side, rust whining about ‘silicon bugs’ strikes me as incredibly immature. Calling their own misunderstanding of speculative execution someone else’s bug. The platform APIs they are calling are explicitly supposed to be monotonic, how is that not someone else's bug? e.g. on Windows they are calling QueryPerformanceCounter and MSDN is pretty unambiguous on the matter  I know there are footguns related to using RDTSC directly but that's not what Rust is doing repiv fucked around with this message at 20:16 on Feb 3, 2020 |

Volguus posted:Plus, it's not like they would gain anything by fixing it. People bought the game with this bug in it, obviously it's not a deterrent therefore spending any developer's time to fix it it's just money thrown down the drain. Yes yes they have billions, so what? Basically there is (was) absolutely no incentive at all to look into it. GTA:Online isn't just something users buy upfront, a significant part of its revenue (on the order of billions of dollars) comes from ongoing microtransactions Players who bought the game but then bounced off the online mode because they got sick of loading are lost sources of MTX revenue. This bug easily cost R* millions of dollars.
