Wouldn't the point of the class action to be to dilute the cost of representation? If the damages per article are high and there's plenty of class members, I imagine the limit would be how much OpenAI has to pay out.

I imagine the problem they're trying to address is ensuring that everyone _does_ only use correctly cast pointers; as defined, it's legal to use that 14 char array, it's just that it's never what you're meant to do.

You can introduce new APIs and new types to resolve the "is it flexible, or is it 14 chars"; that's more or less one of the explored approaches in the article. It won't make existing uses any clearer or safer though, req

I very much care about whether a function can fail or not, and I encourage all the function colouring needed to convey that.

by dwattttt 2y ago
I don't think the mechanics of being able to convey a niche are stable/developer-accessible, but NonZero is a type provided by the standard library: https://doc.rust-lang.org/std/num/struct.NonZero.html

Clearly you need to randomly decide whether or not to randomise it.

You would use interior mutability, putting things in Cells in the map.

borrow checking relies on types to be able to check; types are what carry borrows after all.

PGO describes the using extra data to guide optimisations, but it doesn't define what those optimisations are. Reading the link, there's several that sound like they match what BOLT is applying (Basic Block Optimization, Function

The code linked does the following: - attempt to acquire an RWLock without blocking - if it does, wake the task waiting for the lock - if it doesn't, return "not ready yet" The RWLock is straight from the standard lib; there

If you think about it, that's what Thumb mode on ARM is.

I believe that doesn't indicate it's spinlocking; the `poll` API is specified to not block.

That rather depends. Compile time certainly wouldn't scale linearly with the size of a function, you could well reach a scenario where adding in a line to a function results in a year being added to the compile time.
