I don’t understand why this is a useful effort. It seems like a solution in source of a problem. It’s going to be incredibly easy to end up with hopelessly inefficient programs that need a full redesign in a normal gpu programming model to be useful.

This is an interesting line in the readme:

> The language forces clarity — not ceremony.

I find this statement curious because a language, like this, without ability to build abstractions forces exactly the opposite.

In my mind, cad that you’re not going to manufacture is “modeling”. Not sure if that’s a common verbal distinction.

Breps. Nearly all commercial cad packages operate on boundary representations of objects.

Unfortunately, using a geometry kernel [1] that operates on triangle meshes means this is a no-go for serious CAD usage.

I don’t think it’s falsifiable until there are autism diagnostics that aren’t behavioral. Right now, they’re 100% behavioral, which that any theory that tries to cluster autism symptoms is hopelessly tainted by a recursive definition -> diagnosis -> definition cycle.

I find this type of science is infuriating. Monotropism as a theory of autism or adhd is equivalent to saying that “tendency to focus on a few things” is a theory of autism or adhd. You’re describing the symptoms, which explains almost nothing. A theory of autism would explain the underlying physical causes of the behavior.

As usual, GPT-1 has the more beautiful and compelling answer.

> In this specific situation i constructed that precludes inlining of iterators and allows inlining of for-each, then iterators aren’t inlined.

New comment by nynx in "The ITTAGE indirect branch predictor"

Sure. I can easily see that often being the case for arbitrary code but not interpreter dispatch loops.

I must be missing something here. How would this help predict interpreter dispatch? Those won’t be a function of previous branch history or pc, which may very well be independent of the next opcode. They’d be a function of state in memory or registers.

How did it get into the standard then?

Is it possible to initialize a prng in C++’s std correctly?

It would be insane to put a system as complex as hazard pointers in the C++ standard.

nynx — Mon, 28 Apr 2025 16:34:50 +0000

This is cool for sure. I think you’ll ultimately find that this can’t really be faster than modern OoO cores because python instructions are so complex. To execute them OoO or even at a reasonable frequency (e.g. to reduce combinatorial latency), you’ll need to emit type-specialized microcode on the fly, but you can’t do that until the types are known — which is only the case once all the inputs are known for python.

It seems the product brief is behind a sign-up page. Please indicate to your sales folks that this is highly counterproductive.

Typeclasses are conceptual interfaces. They don’t have anything to do with vtables.

Depending on what kind of software you tend to work on, you may have written a lot of subtly incorrect C.
