1. Free Software / Open Source are Good and True by assertion. There is no God but source code, and Stallman is its prophet. 2. Questions whose answers tend to contradict point 1., such as “Gee, the world runs on Python — as wonderful as job as Guido and his inner circle have done, is it time to ask what an ideal management structure for a technology worth (tens? hundreds? of) billions of dollars might be?” are not welcome — are largely not asked.

An original sin of Free Software which carried through to Open Source and infects HN via its many Open Source believers is a reluctance to take project management seriously. OP shows that Jellyfin’s dictat... er, maintainer is not effectively managing the project. Open Source has no adequate answers (“fork” is not adequate).

Welcome to the human condition, my friend. The good news is that a plurality of novels, TV shows, country songs, etc. can provide empathy for and insight into your experience.

Regarding water specifically, we now have multiple desalination projects of 1MM m^3/day, enough to support a city of 4MM people. They are expensive, but getting cheaper, and real (rich) polities in the Middle East are relying on them.

9. Python got lucky that its inevitable screwups (Python3) didn’t quite kill it.

10. Swift and Kotlin both define programming as serving the compiler (specifically LLVM) rather than serving the coder’s problem. (I haven’t discussed Rust so far since it isn’t attempting to compete with 98% of Python use cases, but if you squint you can see it as going one step further than Swift and Kotlin and in effect forcing the coder to be a sort of human compiler who thinks in types and memory management. This is not a criticism of Rust, BTW.)

0. And behind all of this is Moore’s Law and the demographic explosion of programmers. Python was an implicit, perhaps unconscious bet that if you served people thoughtfully, the tradeoffs with serving the needs of contemporary silicon wouldn’t matter as much.

2. Python is conceptually compact, dominated by hash tables with string keys. The initial leader in the ecosystem, Perl, is conceptually sprawling and difficult to reason about.

3. Python also took lessons from the Unix shell, a mature environment for accommodating beginners and experts.

4. Python had a formal process for integrating C modules from early on.

5. Python’s management has an elegant shearing layer structure, where ideas can diffuse in from anywhere.

6. $NEXT_GENERAL_PURPOSE_LANG (Ruby, Go) weren’t enough better to displace Python. Both were heavily influenced by Python’s syntax, but ignored the community-centric design process that had created that syntax in favor of We Know Best.

7. Speaking of open source entrepreneurialism, JavaScript has become a real rival thanks to the Web (and node), but it is handicapped by the inverse failure mode: where Go is dominated by a handful of Googlers, JavaScript was effectively unmanaged at the STDLIB level for a crucial decade, and now it can’t recover. (I’d also guess that having to write a module system that works well in the chaos that is Web clients and simultaneously the Unix world is a daunting design problem.)

8. Python got lucky that data science took off.

How Earth Got Its Water: A Cosmic Detective Story

The Big Question: How did Earth become a planet with oceans and life, when it formed so close to the hot Sun?

What Scientists Did:

- They used a "radioactive clock" made from two elements: manganese and chromium - Manganese-53 breaks down into chromium-53 over time (like ice melting at a steady rate) - By measuring these elements in meteorites and Earth rocks, they figured out WHEN Earth's basic chemistry was locked in

Key Finding: Earth's chemical recipe was set within just 3 million years after the Solar System formed (that's super fast in space terms!)

The Problem: At that point, early Earth was missing the ingredients for life—especially water, carbon, and other "volatile elements" (stuff that evaporates easily when hot)

Why Earth Was Dry: Close to the Sun, it was too hot for water and other volatile stuff to stick to the rocks that built Earth—they stayed as gas and floated away

The Solution: About 70 million years later, another planet called Theia (which formed farther from the Sun where it was cooler) crashed into Earth:

This collision created our Moon It also delivered water and other life-essential ingredients to Earth

The Big Takeaway: Earth needed a cosmic accident to become livable. Without that lucky collision bringing water from the outer Solar System, we wouldn't be here!

Why This Matters: If Earth needed such specific, lucky events to support life, habitable planets like ours might be much rarer in the universe than we thought.

I found your post “Coding with LLMs in the summer of 2025 (an update)” very insightful. LLMs are memory extensions and cognitive aides which provide several valuable primitives: finding connections adjacent to your understanding, filling in boilerplate, and offloading your mental mapping needs. But there remains a chasm between those abilities and much work.
