MIPS? Or is there something newer

Note that diffsitter isn’t abandoned or anything. I took a year off working and just started a new job so I’ve been busy. I’ve got a laundry list of stuff I want to do with this project that will get done (at some point)

I don’t think that’s true. C++ just has a lot of baggage to deal with and people are doing the best they can with some ridiculous constraints. The sanitizers and things like clang-tidy, and better analysis in compilers seem to be really well received.

I might have misinterpreted what you mean as “standard” (I was originally thinking like you meant that the standard dictates all operations must be safe and doing things like the unsafe/unchecked option references would be outside the standard). I realized that you might mean it like it should be the default behavior, so correct me if I’m wrong there.

Yeah I agree that sane defaults would be nice and that things like unchecked accesses should be more explicit. Having linear types to properly enforce issues with things like use-after-move would also be awesome. I don’t know that anyone has ever accused C++ of being particularly ergonomic. Sum types and pattern matching would be awesome.

Nothing wrong with being a Rust fanboy :), I have written some (https://github.com/afnanenayet/diffsitter).

> but why not just enforce that as standard

I don’t think people want that as standard. The whole point of using C++ tends to be because you can do whatever you need to for the sake of performance. The language is also heavily driven by firms that need extreme performance (because otherwise why not use a higher level language)

There are knobs like stdlib assertions and ubsan, but that’s opt-in because there’s a cost to it. Part of it is also the commitment to backwards compatibility and code that compiled before should generally compile now (though there are exceptions to that unofficial rule).

I don’t think the last two decades of computer graphics research are an Nvidia psyop. Ray tracing is relatively simple and also reflects reality (you’re literally doing a light simulation to approximate how we really see). It’s always been the gold standard for rendering, we just didn’t know how to make it fast enough for real time rendering.

Generally speaking more volume is good. I’m happy I can buy/sell most of my stocks instantly and that I don’t pay execution fees. I don’t think most average traders operate on a horizon/scale that’s directly competing with institutional funds.
