Rachel Entrekin has won the Cocodona 250 outright in 59:09:48, breaking the overall course record by over 2.5 hours. Second place / M1 is still well over an hour out, and F2 is at least 4 hours behind. One of the most amazing ultrarunning performances in recent memory, simply spectacular!

The project was setting up a pump to pull water from our rain tanks into a new paddock, so it involved both plumbing and wiring — the two most fiddly disciplines, you really need the right parts, improvising is bad. Then I ran out of 90° elbows, discovered the pump had a leaky fill plug, cracked the waterproof electrical junction box, and to cap it all off discovered at the last minute that I’d installed the pump backwards.

You can measure your skill at DIY house projects by the ratio of visits to the hardware store against days of work:

- no visits: god tier
- less than one visit per day: excellent, you know what you’re doing
- 1 visit / day: average

@rami@chaos.social I mean probably - but also you could say a similar thing about shifting the maintenance burden from assembly to compiled languages, from compiled to interpreted, etc. Higher level abstracts are A Thing, I don’t think it’s a huge stretch to imagine an even higher level where we’re specifying whole swaths of applications in a few lines. I guess if you want to be charitable you could say “that’s a prompt!” but the fuzziness and nondeterminism of LLMs make it real hard for me to be charitable.

@glyph@mastodon.social Yeah, that’s one conclusion I’m coming to thanks to this discussion. I was aware of the slipperiness of “quality”, and was kinda doing that deliberately because exploring weather quality matters is (to me) more interesting than defining quality precisely. But what I hadn’t noticed was that “done” was just as slippery — and in order for quality (whatever definition) not to matter, there has to be no maintenance, and that requires “done” to actually be a thing.

@pythonbynight@hachyderm.io @ambv@mastodon.social Ok yes I like this: “explainabibility” (I need a better word but fine) is one reason why code quality matters. Like, if a dam fails, we’d really like to have the blueprints — and for them to be readable! — so we can figure out where we screwed up. “The dam works because the lake holds water” isn’t sufficient.

Specifically what I find fascinating is: the tooling that would be required to make agentic engineering begin to live up to the hype — much better testing tools, formal business logic specification languages, more powerful and easier to use formal verification tools, better static analysis tooling, etc — would be massively useful to software engineering quite regardless of the existence/utility/quality of LLMs. (4/5)

@adriano@lile.cl @frank@frankwiles.social @janl@narrativ.es It’s frustrating because the thing I was trying to discuss about the question of why code quality matters, not yet another “LLMs: good or evil” argument. And for the most part replies have been focused on that — and have really teased out some super interesting points about what “quality” means and why it’s important. And in doing so I think makes a much better case against agentic coding ever working the way proponents claim it might!

@janl@narrativ.es To be clear - my position is that genAI is on balance probably a net negative and if I could unring the bell I would. But also I would say that about the internet — and “there are good things about the internet” is hardly a controversial option (I think?). I get that The Discourse demands extreme opinions but I don’t think it’s “falling for a scam” to find positive things about AI, and I think it’s dead wrong to approach ANYTHING without a sense of curiosity.

Code quality has always been ONE factor; it’s never been always the most important. Eg we often accept complex internals as the price for a clean external API; and we all write sloppy code for one-offs, prototypes, etc. So part of me accepts the “code quality doesn’t matter” argument. I can see a vision of agentic engineering with systems that prove correctness; if an agent produces code that is provably correct, maybe the quality really doesn’t matter! (2/5)

Look this isn’t at all a defense of slop code, but it has me thinking — how much does code quality matter, and why?

It’s maintenance, right? We care about readability because we know we’ll have to make changes, fix bugs, etc.

But so … imagine a codebase that’s magically bug-free and feature-complete. (I’m aware this is a strawman - that’s the point, it’s a thought experiment.) Does it matter if this codebase is well-written? I’m not sure it does! (1/3)

I’m far from convinced that this is actually possible. It’s certainly not now — and I’m not talking about models. Testing and verification tools are nowhere near where they’d need to be, regardless of model quality. Today, code quality DOES still matter; even the best-case version of agentic engineering can’t produce code that’ll never require maintenance. But I can see a possible future where code quality might not matter, or will matter a lot less, and that’s FASCINATING. (3/5)

I do believe that people can change, and that there can (and should) be a path back to good standing in a community.

But that path needs to involve taking ownership of the harm they caused — even if, heck especially if, they’re no longer a person who would do those things. And they need to at least attempt to make amends in some way.

Without these things, I’m not going to be able to assume good intentions of someone trying to come back.

For folks who’re interested in 3d printing whistles: https://www.printables.com/model/417238-loudest-emergency-whistle is the best I’ve found. They’ve been tested on canyoneering trips — we use whistles to communicate over the sound of waterfalls; nothing else is piercing enough to cut through the thunder. These work as well as the gold standard Fox 40 Classic. I print it florescent orange PLA, with an 0.6mm nozzle and 0.3mm layer height, and make lanyards out of orange paracord.
