Project mention: Compiler-Assisted Floating-Point Error Analysis and Profiling with FPChecker | news.ycombinator.com | 2026-07-01
I was expecting them to be aware of https://herbie.uwplse.org/ Herbie but it seems like either they don't know of it or they don't see it as relevant.
My hope for the future is that Herbie's approach can evolve to a point where the person writing the software doesn't directly write FPU operations, any more than you'd manually work out all the best ways to optimise integer arithmetic. You write what you meant and the compiler figures out how to deliver that with FPU instructions. The parameters are more complicated for the second operation, but it's surely tractable.
"I want to calculate function F(x) here, I care about 0 <= x <= 4.0, inside those limits we need +/- 0.1% accuracy, for other values I don't care, and I want you to go as fast as possible within those parameters".

HW-HTML-Drafting-Project
Keyboard like VI. Work in the browser, completely offline. New Program State Manager/Animator. Open-source forever.
Project mention: Needing input on my HTML drafting program's menu system | news.ycombinator.com | 2025-10-01https://github.com/dckimGUY/HW-HTML-Drafting-Project/wiki/Ho...
So far we have come to one very important conclusion: This program desperately needs an 'add' menu. By this I mean a grid of specialized parts that are sort of 'ready-made' and that way the user won't need to understand which CSS properties will give them which thing...
We'll just make up the parts and put them there in some sort of 'part-adding-menu'. Most programs have something like that.
This way, when the user is first entering into the program, there can be a button to simply enter in a new 'editable HTML' part.
To give a little bit more insight into the program: I can tell you that there is a 'single-atomic-component', meaning that every rectangular part that you are seeing is actually made with the same parts inside, regardless of whether they are being used.
This was unavoidable as a choice for the base of this program.
If anyone can, please follow up with some part descriptions for the add menu. One with editable text placed obviously inside of the rectangle has already been suggested. Are there any other 'standard' parts that you know about?
Thanks,
