A model trained only on public domain/cc0 works would be a counter example... but this ain't one.

No, that model is trained on CC-BY and similarly licensed works that demand attribution - which the resulting model does not give in the required manner. It violates copyright to the exact same extent that training on all rights reserved data does.

This is disappointing. He was by far the most interesting candidate (not necessarily the same as best). Putting for proposals to do things instead of trying his hardest to just repeat sentiments everyone in the party agrees with...

The week long deadline the eighth circuit here seems in violation of that ruling, which imposed its own deadline of merely "timely sought". The word timely is explicitly defined in SCOTUS rules for a petition for a writ of certiorari to mean 90 days, not 7.

And before anyone gives the eight circuit credit for the pause, SCOTUS explicitly stayed the district court ruling until after SCOTUS had a chance to review any eight circuit decision. The eight circuit didn't have the power to not grant a stay here.

Lean's dependency resolution is... apparently... interesting.
Screenshot of terminal: Some mismatched dependencies come transitively from other packages in your lakefile. Try putting `require mathlib` last in your lakefile so that Mathlib's versions take precedence, then run `lake update`.

Re 3) I imagine this makes the contempt proceeding a lot less popcorn worthy though. The chance that the state doesn't just immediately back-peddle is now approximately zero. Before you could imagine things like Hoskins being imprisoned for contempt - refusing orders to countermand his last email.

You can then make a local proxy that forwards to tailscales servers without sending SNI, tell tailscale to use that proxy as the control plane, and everything just works.

Greg @gregmorenz.bsky.social · 09/09/2026
I was sitting around in a hospital waiting room that blocked tailscale... and occupied myself by figuring out how to bypass it. If they're blocking via SNI sniffing like the hospital was - tailscales servers don't care if you set an SNI.

In the example I question the utility of the descriptions of the colours - instead of noting which cards were modified (what the colours mean)... It has a lot of detail, but not the right detail... less verbosity OR the right detail would be better... I wouldn't be satisfied if it was my writing.

The practice seems fine to me if you're reviewing the text for quality. Otherwise, probably controversially, I'd wonder if it's better than doing literally nothing (AI models improve - saved alt text doesn't)

We need more innovation on things like cheap effective sound barriers. Quality of life improvements from quiet cities (and cons...) without requiring everyone be quiet would be massive.

Some initial thoughts, and a complicated mix of feelings. Wow. I mean, Erdos problems are cool (I genuinely mean that), I didn't know about the Jacobian conjecture before it got disproved. But this newest batch from OpenAI hits home in a way the previous announcements did not.

A woodcarver named Becky W (vortenjou.bsky.social, rosehip.wordpress.com) made a sculpture of my nuthatch comic, showing a white-breasted nuthatch sitting on real nuts and hatching one of them. I'm so happy
A wooden carved and painted sculpture of a white-breasted nuthatch sitting on some nuts with a nutmeat with wings flying away into the sky.A four-panel comic. The first panel shows an arrow pointing down at a happy-looking nuthatch bird, and a caption: This is a nuthatch. The caption says "It's called a nuthatch because... wait no" and we see the nuthatch standing on a pile of nuts, tucking them under it. The caption says "That's not... wait" and the nuthatch is roosting comfortably on the pile of nuts. The caption says NO. And we see that one of the nuts has hatched and some walnut meat is flying happily into the air on little wings.

Around here e-bikes are bizarrely not "motor vehicles" by law. There are signs against motor vehicles on paths where some classes of e-bikes are explicitly allowed. There are laws like non-bylaw-speed-limits that bizarrely don't apply if you're on a (e)bike. It's like it's designed to cause chaos.

Great piece explaining why Canadian fires by and large are not the result of forest management issues & for the most part cannot be fought, only mitigated near infrastructure and inhabited areas. Non-Alaskan US views of fire management just do not apply. www.theclimatebrink.com/p/canadas-bo...

Canada's boreal wildfires aren't just bad forest management
Higher fire season temperatures are strongly correlated with increased area burned

Yeah, I'd be pretty happy with that. Perhaps the way to think about this isn't as an admin action, but as remote management for my own devices? Not sure how much sense that makes when scaling away from personal tailnets though.

Greg @gregmorenz.bsky.social · 11/07/2026
As a default enabled thing, definitely terrifying. I have friends on my personal tailnet and don't want me getting hack to imply they get hacked... The control plane now becomes an avenue for a cyber attack with huge blast radius (though tbh I assume any software with auto updates already is).

Greg @gregmorenz.bsky.social · 08/07/2026
Yeah I was proposing solutions that easily show we can improve the problem. Not necessarily the best solutions (I haven't done the work to have a strong opinion on what those are). That said, the numbers above show that line 1 is better but still really really bad.

I strongly doubt - though I don't have studies to back this up - that the cost of fixing this is anywhere near the cost of the healthcare and lost productivity caused by the effects of the PM2.5. Penny wise and pound foolish because the pennies are easier to attribute...

Need an edit button, μg/m^3 not "micro squared g/m^3" lol.

Greg @gregmorenz.bsky.social · 08/07/2026
E.g. this study claims the difference between a road and background is ~2 μg/m^3 - my gut feeling is that's probably an underestimate since the sensors aren't literally on the road like a bike is, but not by an order of magnitude: www.sciencedirect.com/science/arti...

Greg @gregmorenz.bsky.social · 08/07/2026
Roads aren't perfect, but they're nowhere near the hundreds of micro μg/m^3 the subway is. Probably would be worse if you stuck them in a similar tunnel. Not unavoidable at all. Doors keeping the dirty break air in the tunnel and off the platform for instance. Or cycling in more outside air.

I'm seem to be more sensitive air quality than most... but surely you can smell the break dust... that sort of fine particulate isn't good for you long term even if you have no immediate reaction. Googled it out of curiosity and here's some numbers: www.sciencedirect.com/science/arti...

None of this is fundamental. But the city I'm in (Toronto) just doesn't seem to care about making transit pleasant being some low minimum threshold. And I have the luxury of alternatives thanks to not being disabled, and money.

Greg @gregmorenz.bsky.social · 08/07/2026
I've almost entirely stopped. The transit is just unpleasant. Terrible air quality in the subway. Terrible suspension on the bus. So unreliable that biking (with a cheap ebike) let's me leave later and get there on time more reliably. Or driving when I don't want to bike for whatever reason.
