Regression vs. Classification in Machine Learning
Same data, different questionโand your model changes because the decision changes.
This post explains how to choose the right framing, how labels and metrics differ (RMSE vs AUC, etc.), and why โturning regression into classificationโ can change what the model learns in practice.

Or really, I should just rewrite this as a VRP, since it is so close to that anyway and the code I have was just a prototype.

Probably the dumbest prank I ever pulled was at the end of a Python programming class. I wrote two versions of the required programs. The first was in Perl and I gave them a .py extension. Then I wrote them in Python and gave them a .pl extension. Because I was on #Linux, I then used the proper shebang line so the programs would run correctly. I explained when he ran the Python programs that the Python files had the .pl extension. #python #perl #programming

Four options for ๐๐จ๐ฉ๐ฒ in Python:
๐๐๐๐๐๐ ๐๐๐๐ข
๐๐๐ ๐๐๐๐๐๐_๐๐๐๐ข(๐):
... ๐ = ๐.๐๐๐๐ข()
... ๐[๐ท] = ๐[๐ท].๐๐๐๐ข()
... ๐๐๐๐๐๐ ๐
๐ = [[๐ท, ๐ธ], [๐น, ๐บ]]
๐๐ท = ๐
๐๐ธ = ๐.๐๐๐๐ข()
๐๐น = ๐๐๐๐๐๐_๐๐๐๐ข(๐)
๐๐บ = ๐๐๐๐ข.๐๐๐๐๐๐๐๐ข(๐)
c1, ๐๐ฌ๐ฌ๐ข๐ ๐ง๐ฆ๐๐ง๐ญ: nothing is copied, everything is shared
c2, ๐ฌ๐ก๐๐ฅ๐ฅ๐จ๐ฐ ๐๐จ๐ฉ๐ฒ: first value is copied, underlying is shared
c3, ๐๐ฎ๐ฌ๐ญ๐จ๐ฆ ๐๐จ๐ฉ๐ฒ: you decide what is copied and shared
c4, ๐๐๐๐ฉ ๐๐จ๐ฉ๐ฒ: everything is copied, nothing is shared

A true Traveling Salesman Problem on top of the Knapsack Problem takes longer than I want to spend (many minutes vs ~10s) and also does more than I want.
A forced-greedy TSP (near neighbors are all scored 1, farther nodes are all scored 0) is much faster and closer to what I want but still longer than I want (~2m)
The solution to a combinatorial problem is not a faster algorithm, it's a smaller problem.
I need to break the TSP into chunks and solve them separately. The difficult thing is that I need to do this while deliberately remaining unaware of the semantics of the nodes for larger architectural reasons.

Oh "great", uv does the same thing, referencing the pip code: https://github.com/astral-sh/uv/blob/1723ed00d6e6961abcf05d09abe59aaee005a6af/crates/uv-client/src/linehaul.rs#L61-L63
Added after someone who seems to be a #PyPA member filed an issue requesting it: https://github.com/astral-sh/uv/issues/1958

I recently created a lightweight #Python web app that analyzes a stock portfolio against recent market performance. It uses FastAPI and yfinance to pull real-time data and compares the current value of each position to its highest price over the last 30 days. You can upload a CSV of your holdings, and the app gives you a clean summary of where your portfolio stands relative to recent highs. If anyoneโs curious, here's the link:
