Author here, if that word still applies to code written with the help of an LLM. I paired Russ Cox’s idea to add images inside QR code [1] and spelling out the contents in a low resolution bitmap font. [1] https://research.swtch.

You can do it a bit faster by not quicksorting the entire array, as you don't really care about the order of the lowest and highest numbers as long as they are not close to the middle. There is also an approximate algorithm that does n

For Opus 4.8, 142.3k input, 2.0m output for the entire project. No longer have access to Fable 5 to check.

Corrected the dates, thank you! What are the other errors?

by dimview 3mo ago
Thank you. Of course the dates were out of order. The Java library (com.hp.creals) is 1999-2004, paper is from 2005. Unfortunate price of LLM-assisted development. Corrected.

That should be doable, too. Maybe as a next project.

This is different from a CAS. For example, if you ask it to do exp(100)+1-exp(100), it does not rearrange and cancel out the two exp(100)s. Instead, it does exp, addition, and subtraction, all with as many digits as you ask for.

Correct, but if you don't know the next digit is 2, you can think it's all 9s, another representation of an integer number.

Author here. I could not find a constructive‑reals calculator on iPhone, so I ported the engine Android uses: Hans Boehm's com.hp.creals plus AOSP's UnifiedReal/BoundedRational. Used Opus 4.8 to do the port and Fable 5 for th

Looks like it uses seven colors (including bodies of water). Can it be done with fewer colors? The four color theorem does not quite apply, as all bodies of water have to be the same color.

Eskimo bowline is non-exploding, nevertheless I wouldn't use bowline (or eskimo bowline) while rock climbing without somehow securing the working end. Kalmyk loop (which is exploding variant of eskimo bowline) is probably not secure enough

Kalmyk loop is exploding - pull to untie. Bowline is not. Bowline requires stopper knots when used on on modern ropes, otherwise it can slip. I've never seen kalmyk loop slip. Both are simple and can be tied around things.

Why does everyone likes bowline so much when eskimo bowline or kalmyk loop ( http://dimview.org/knots/ ) is much better?
