My answers to the questions I posed about porting open source code with LLMs

Last month I wrote about porting JustHTML from Python to JavaScript using Codex CLI and GPT-5.2 in a few hours while also buying a Christmas tree and watching Knives Out 3. I ended that post with a series of open questions about the ethics and legality of this style of work....

Quoting Linus Torvalds

Also note that the python visualizer tool has been basically written by vibe-coding. I know more about analog filters -- and that's not saying much -- than I do about python. It started out as my typical "google and do the monkey-see-monkey-do" kind of programming, but then I cut out the middle-man -- me -- and just used Google Antigravity to do the audio sample visualizer.

A Software Library with No Code

A Software Library with No Code

Provocative experiment from Drew Breunig, who designed a new library for time formatting ("3 hours ago" kind of thing) called "whenwords" that has no code at all, just a carefully written specification, an AGENTS.md and a collection of conformance tests in a YAML file.

Pass that to your coding agent of choice, tell it what language you need and it will write it for you on demand!

This meshes nearly with my recent interest in conformance suites. If you publish good enough language-independent tests it's pretty astonishing how far today's coding agents can take you!

MAGA’s Foundational Lie

Jeffrey Goldberg in The Atlantic (gift link), on the fifth anniversary of the January 6 insurrection and the first year of the second Trump presidency:

We have been watching indecency triumph in the public sphere on and off for more than 10 years now, since the moment Trump insulted John McCain’s war record. For reasons that are quite possibly too unbearable to contemplate, a large group of American voters was not repulsed by such slander — they were actually aroused by it — and our politics have not been the same. Much has been said, including by me, about Trump’s narcissism, his autocratic inclinations, his disconnection from reality, but not nearly enough has been said about his fundamental indecency, the characteristic that undergirds everything he says and does.

A soaring US vs a stagnant EU? “Europeans benefit from more leisure time than Americans, higher life expectancy & lower inequality levels, all w/ comparable productivity rates. However one looks at it, this is a considerably better economic performance.”
