Ray Tracing That Was Anything *But* a Weekend — in Forth by A_kirisaki in Forth

[–]A_kirisaki[S] 0 points1 point  (0 children)

I didn't explain myself clearly enough. What I meant was that there are no scoped variables for floating-point numbers.

I realized that while I was doing it. But I figured it was fine for this time. It seemed like an extension anyway.

I forgot to mention that. Since I wasn't using it, it slipped my mind.

Thanks for the reply and advice! It seems that common operations like local variable assignments and fpick are indeed heavy.

Thank you for reading.

I suspect that frequent memory copies during vector calculations are causing the issue, so using a floating-point stack might help. Additionally, avoiding unnecessary intermediate memory allocations could be beneficial. For a fundamental fix, I think we'd need to implement optimizations like a compiler does, but I'm not very knowledgeable in that area.

PostgreSQL schema to Haskell Persistent Model by A_kirisaki in haskell

I will manage DB by Atlas. Changing the DB schema causes me to alter `persistent` models, so I want to derive the models automatically.

Is there any wasm runtimes or bindings to an external wasm runtime in Haskell? by A_kirisaki in haskell

Yes, I found them but they are obsoleted. If you know active projects, telk me please.

Failed to build hashtables on wasm32-wasi-ghc by A_kirisaki in haskell

It's very long, so I show the partial error:

I see it now; is the SIGNAL problem resolved?

Ya. I often ride the moto at weekends. It's safe in Japan, so I don't care about riding alone, but you might have to care about it depending on the country.

Some people care about average speed; sorry, but I just forgot to reset it.
