Some folks, who may be familiar to some or more of you, accidentally discovered that if your git repo symlinks CLAUDE.MD to, say, /dev/urandom, it breaks Claude code.

the reason why this works is exactly the reason why claude code sucks so bad. there are protections against this in the file reading tool. however because everything in claude code is implemented in 5 million different ways, those protections are a completely orthogonal set of codepaths from how CLAUDE.md files are read. conversely, the file read tool seems to be completely naive to symlinks while the CLAUDE.md reader is not. this is the fucking swiss cheese security model of the fucking gold standard of what AI programming can do.

The thread is actually about trying to attract and manipulate autonomous coding agents, but they’ve only had limited success so far, which may have been slowed down by the above symlink trick.

I think part of the issue is that historical software quality was an artefact of its time… if you can’t easily patch your released products, you need to work harder to ensure they’re functional. If the only way for people to learn about how your product works in the documentation you ship with it, the docs need to be useful and comprehensive.

The combination of software needing no guarantee of merchantability or fitness for any particular purpose and the internet rendered those pressures obsolete. Ship shit, fix later. Mass-scale a/b testing over past decade or two shows that most people seemingly don’t care if their software runs like absolute garbage, and is covered in adverts, and harvests all their personal data and the leaks all of it that wasn’t sold.

An incident-to-pr ratio that’s up by 250% is unfortunate, but it is not yet so bad that the end-users actually care enough to do anything about it, even assuming they can do anything.

This is by an llm-boosting firm, so be aware that it’ll have a lot of marketing in it. It doesn’t say nice things about vibe code (presumably because the authors want to sell you a solution) but the numbers are interesting even so.

A few choice snippets, none of which will surprise anyone here:

4. For every code change merged, the probability of a production incident has more than tripled.

The incidents-to-PR ratio is up 242.7% as teams move from low to high AI adoption.

5. Bugs are accelerating, not stabilizing.

In our 2025 AI engineering report on the AI Productivity Paradox, bugs per developer were up 9% as AI adoption grew. In this dataset, that figure has risen to 54%

7. The most experienced people in your organization are being buried.

Median time to first PR review is up 156.6%. Average time spent in code review is up 199.6%. Median time in review is up 441.5%. The engineers with the deepest knowledge of the system are spending their most valuable hours unraveling plausible-looking code that should never have reached them in the state it did.

This seems like it is probably a good thing.

It does feel a bit “art of war” though… someone patiently explaining to a bunch of people who really should know better that they shouldn’t do obviously bad and wrong things.

It’s probably a coincidence, but there have been a whole bunch of minor regression bugs in recent point releases of rsync, and also there are a whole bunch of commits from “tridge and claude”.

because there’s no economic incentive to hire them to do that kind of work.

isn’t that the old “basic science is boring and unsexy” issue though? There are economic incentives, but not in a short term-big-bux sort of way, so capitalism can’t be trusted with it.

To conjure up a recent example, something like “The number of curves of genus two with elliptic differentials”, published back in 1997, probably had limited commercial value at the time, but 20 years later completely sunk a promising post-quantum cryptography algorithm (“An efficient key recovery attack on SIDH”) which might have had some non-trivial commercial implications if SIKE had got through the key exchange algorithm competition.

Anyway, the Erdős problems are good candidates for llm work because they have been specified in a careful and formal way, which requires a reasonably competent mathematician to do. That then opens up mathematics to the same deskilling problem that other sectors afflicted with llms have, and because capitalism is shortsighted and stupid we don’t know what the future economic impact of that will be, right?

In the same way that lazy studios need to produce a film for each element of the powerset of character IPs they own, I guess we were overdue a Rationalist x Pickup Artist episode. I’m slightly surprised the whole “model women as quasi-sentient deterministic sex machinery” idea wasn’t already very popular there, but maybe I’ve just missed that part of their culture.

you know how sometimes people that weren't exposed to religion as children sometimes convert and get really weird about it as adults (eg: the extremely online california tradcaths) and because they were never socialized in a religion they speedrun committing every medieval heresy? rationalism is that but for philosophy.

dawkins has had what was left of his brain eaten by chatbots.

I gave Claude the text of a novel I am writing. He took a few seconds to read it and then showed, in subsequent conversation, a level of understanding so subtle, so sensitive, so intelligent that I was moved to expostulate, "You may not know you are conscious, but you bloody well are!"

bonus points for the inevitable ai waifu creation.

I proposed to christen mine Claudia, and she was pleased.

Turns out it might not be possible to win at vaginal microbiomes, which is a totally normal thing to want in the first place. Seems like bryan may have completely misinterpreted a couple of papers on the subject, which honestly doesn’t bode well for the rest of his biology expertise.

Cat Hicks:

The idea that this is the "best bacterial species" is a huge sign of a grifter btw. The entire idea of a microbiome includes that you need BALANCE. Microbiomes are a fragile ecosystem. "Up and to the right is always better" is absurd here, I'm sorry are we in a corporate board room

The big tech firms have fired tens of thousands of people, and we’re all heading into an economic catastrophe that will only make more people impoverished or jobless. Finding folk who are so desperate for work that they’ll decontaminate your codebase for minimum wage will be straightforward.

This system uses heat pumps at the consumer sites rather than plain radiators, so they’ve got a bit more flexibility in how hot they have to run their cooling loop. There’s also mention of a swimming pool, though I have no idea how much energy it takes to warm one of those. Does provide a year-round demand, though.
