I heard about St. John's from a twitter thread and find it deeply baffling. It's as if a group of monks wanted to keep the quadrivium and trivium but their clock stopped at the 16th century. One of their faculty proudly said they

The boundary lines of the convex hull can easily have 3 points each. So not as obvious as all that.

The Appolonius circle is a theorem in pure geometry. It is used in the 'method of images' in physics. And not just for ancient textbook problems either. I saw a paper in experimental fluid mechanics that builds up the intuition wi

I work on vehicle routing for a living. Our routing engine is mostly original heuristics, no MIP. The thrust of your remarks is correct IMO. We are forced to support a large number of granular constraints, too large for my comfort. But no s

I'm curious too. And what are the far better alternatives in your opinion? Hexaly claims to go far beyond MIP. Amazon uses it for packing VMs into servers. This video by one of their research scientists was widely circulated at the tim

How did you straighten it out? I am drowning in gating propagating semantic mismatches...

It's a bit confusing now with Numba Cuda also being officially maintained by Nvidia. Also Cuda Python, which looks older. Which of these - warp, numba, cp, is the best bet for a beginner? https://nvidia.github.io/numba-

I wrote a logistics optimization program (think travelling-salesman++) in Python and it gradually took over from the v1 version written in Java. People generally compare "speed of execution" to "speed of coding". I'

I did not. Post-conditioning by your comment and the other one,I can see some signs such attempting to be unusually comprehensive. The 'atoms in your liver' could be an awkward human trying to be poetic about scales. I still don&#

I can roughly guess the train of thought and I am a bit surprised that Claude is failing you. That said, I am puzzled at the algorithms that Claude & GPT "get" and ones that they do not. (former physicist here. would love to k

I wonder how many completely u related applications have that interval check logic coded up somewhere. I'm pretty sure I wrote one for my work codebase. Would I bet my life that the < and <=s are correct? Nope.

Yes that's a brilliant article. I do not think it is in the book yet? I used a poor man's version to solve a puzzle where one arranges polymino pieces on a grid spelling out the date [1]. No pointers, just keeping track of deleted

Hey I am trying to get back into German. What are some of the good channels that you've found? I remember Fokus Deutsch. Spent 4 years in Germany but never took a course out of sheer laziness. I can read children's books but every

Ah this is great. I wrote my own solver in Python+Numba. You've probably seen Robot Reboot https://www.robotreboot.com/challenge . I had a parser that could take a screenshot of the daily puzzles and feed them into my e
