In a good team, it would be joint responsibility. But you make a good point; typically the accountability would be split across engineering and product. So I guess that’s a new interesting difference: you feel less connected to the engineering calls with coding agents, and so accountability slips

you produced it, exactly from the product manager perspective.

PDF Accessibility and Standards – Quarto Quarto 1.9 brings PDF accessibility and standards support, building on new tagging features in LaTeX and Typst.

If you are interested in PDF accessibility, there has been some big progress in Quarto.

Take a look at the latest blog post: quarto.org/docs/blog/po...

At some point a friend of mine was trying to tell me about natural gradients, which I guess is what this is also trying to do in a sense? (natural gradients look at everything under the Fisher curvature or some similar gobbledygook)

sure, I know what that term means, I totally am not reading that paper right now. No, not me.

I'm not raining on the parade, I think it might work! (ie, the math checks out) It's just that I feel like there will be a Hessian term in there somewhere, and I don't have an intuition for how big that'll be.

*Up to second order

But yeah, extremely cool! Have you seen the graphics tricks people do to simulate signed distance fields to a surface defined implicitly by f(x) = 0? It's, more or less, "divide by gradient magnitude", which won't surprise you at all

Brutal, but evidently correct in that context. The whole piece is worth reading.

You can almost see the trajectory in latent space. Pure markov chains on word sequences have no notion of word or structural similarity, and this does. But otherwise, yeah, 100%

Sure but Gemini did this after messing up some regression code or something

I might have made that exact joke in the company chat, yeah. Takes one to know one 😬😬😬

We don’t need to have a discussion of whether these things have any internal experience in order to have a good guess at what a transcript like this would do to someone whose head is not in the right place!

This was mostly unprompted and entirely accidental after it realized it had made a bad analysis (or something like it, I can’t quite remember)

Have you ever experienced a Gemini freakout? This is extremely bleak but completely unsurprising to me. Let me find a screenshot, hold on

I also don’t think most people have tried hard to make LLMs good for *debugging*. They’re weirdly excellent at it (arguably better than they are at writing code, which is a genuine surprise!). You do need to want to use it in that way, and to be willing to put in the effort

It took us a long time to get our code base to a point where opus can be helpful, and I agree with you: *this* is where I’m excited about LLMs for coding. *we* know what needs doing, but it’s a hell of a lot of different cases, and it’s a real drag to do the handling all manually. Opus helps a lot!

* typing out code is definitely one of several time sinks, if you take your job seriously and spend a lot of time exploring options
* it is not the only time sink, but it is one
* claude can help explore a design space in a less committal fashion
* this makes the harder parts of eng more tractable

Hey, for real. Think of this as a friend telling you to log off, for just a bit. It’ll be good for you.

Well, the awoo in Tucson is all the coyotes. But dude, it's like half as loud as the tornado awoos. It's wild.

04.03.2026 19:21 πŸ‘ 2 πŸ” 0 πŸ’¬ 1 πŸ“Œ 1

I lived in Tucson before moving here; there's _way_ more coyotes there! They own the place pretty much lol

04.03.2026 19:19 πŸ‘ 2 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

In Tucson the awooo is at 1am. Here’s it’s at 1pm lol

This is the single weirdest Minneapolis thing I experienced since moving.

No one told me about this when I moved and it freaked me out!!

The new iOS is terrible, something simply Must Be Done about Apple's insistence on making everything rounder and more transparent to the point where I can't read any fucking text on the screen
