Asking a silly question… what piece of kernel code do you find the most awe-inspiring or impressive?

The top claim is that it's "Incredibly Fast" but I can't find any performance benchmarks. Can anyone find a link?

R-Trees are a good data structure to use in this case, enabling you to query a collection of intervals for overlap with another in O(log(n)) time.

Just to clarify, this requires both the client and the debugging script to be running 3.14? So I cannot have a script running an older version of Python but use a Python 3.14 debug script to attach to the running script?

Yes

If I had the Infinity Stones [1], I'll redefine human legal, political, cultural practices and beliefs so that we set right fitness function as it relates to 'survival of the fittest'. Nature evolved its own criteria for what is fit and unfit. We humans have twisted those around with our beliefs and systems, often for good, but often incorrectly and often inconsistently.

'Fit' cannot be meaningful unless 'unfit' too is, and the unfit are set to some real disadvantage. Trying to attain equality over both fit and unfit is detrimental when taken collectively. Having ethics defined in a way that in practice, those who follow ethics suffer more while those who don't follow have higher chances of success, is not good.

> [numpy] stores everything in rows

This isn't true. Pandas uses Numpy to store columns of data. Theres quite a few technical errors in the article.

Isn't heat free energy in a place like London? I know very little about metro systems so please correct me if this is insane: wouldn't the people living above the tubes be happy to get a heat exchanger (passive) or heat pump (active, but takes more of the heat) that prewarms their hot water supply? People still take warm showers and boil tea and rice/pasta in summer, and in winter the purpose should be obvious. If the water comes in at 30 instead of 10 degrees C, you need to add only a few degrees for showers and floor heating

What do you do in the summer when the homes don’t want the heat?
