Does it have rust versions of the full stack of libraries like Agnis Johnson's Clipper, etc? How compatible is the kernel with CGAL Rational?

i just took that pesky 's' out of https and it let me click thru.

It's not dead. It's included with every copy of Desktop Excel and probably will be for 20 years. Press Alt-F11 and away you go (enable Developer tab first i guess?). Forms, SQL connectors, collections, alot of other stuff even XML parsing is in there somewhere if you dig around enough.

I mean it's like. not being developed anymore and not added to, and its a pain to have it deal with modern stuff like https but. yeah. its only mostly dead.

Surprised Wildberger’s youtube channel wasnt in here.

People ask whats the point? For me the study of the infinitesimal vs finite has really helped me better understand issues of precision and approximation in computers. I feel like I know exactly why 1/3 plus 1/5 is not exactly 8/15 in my Calculator app. Or why points in my 3d object face are not coplanar after rotation. Or why games have weird glitches when your character is too far from origin point. Or why a spreadsheet shows rounding issues

Jaquard loom was one of the first machines that could operate based on a set of symbols / patterns encoded on a punched card. Computers ran on punched cards until the 1970s. Voting machines used punched cards until pretty recently (infamous "hanging chad" from 2000 US election).

I had this feeling of alien math when I went thru his videos on ancient Babylonian math. They were very serious about the everything divided by sixty stuff. Good times.

The other thing it can give you is computationally exact results since rationals are closed over division. Sine is interesting because where the input is rational the output is almost always irrational and where the output is rational the input is almost always irrational. In computation the first time you use sine in a program you have injected approximation. If you want to build things like reproducible code and geometric caching it can be interesting to compare using a purely rational computation system to an approximative system.
