We should stick to humans. They never do anything stochastically.

Oh no, stochastic? Sounds bad.

I do like that one bolded item here is "strong treatment."

Basically, my (limited) experience is that Claude Code is delightful. If there’s a way to make that uniformly better, sign me up.

I just realized that need an explainer article or video on what harnesses actually are, how and why they vary, and how they affect model/agent performance.

The only thing I’d caution is “be careful what you wish for.” It felt like the product that finally got a majority of normies to use the web regularly was Facebook, and, well…

Another part of it is that everyone is now willing to pay lip service to CA needing more housing. It’s now harder to figure out which politicians really mean it.

Yeah. A klaxon or two would really brighten things up.

I feel like the endorsements of a few YIMBY orgs have become less reliable lately, but I don’t have a strong theory for why that is.

Best guess is that is they lose focus and start making recommendations that are closer to what you might expect from a generic left leaning group.

Evolutionary branching of social preferences in a public goo We study the evolution of other-regarding preferences in a public goods game where the production function exhibits varying degrees of complementarity between individual efforts. Individuals are ratio

🧵 New paper w/ Guillaume Cheikbossian: "Evolutionary branching of social preferences in a public good provision game" (ideas.repec.org/p/tse/wpaper...). Can behavioural heterogeneity in cooperation be an adaptive outcome? We think the answer is yes.

I think what any one course can do is very limited, but I’ve been experimenting with “do overs” that still preserve students’ incentive to buckle down. E.g. if they do better on the final, I’ll use it to replace their midterm.

Maybe it’s an onramp for students who developed bad habits? We’ll see.

Yeah. I try not to over extrapolate, but the grading distribution on the midterm in my undergraduate class was more bimodal than in the past.

A week later, I’m still thinking about this. Yes, a strong, fighting, anti-corruption message was part of it, but that alone wasn’t enough.

Hungarian progressives knew they needed a supermajority to undo Orban’s regime, and accepted the costs needed to achieve it.

So, I agree that — back when your boss was less likely to have also attended a critical theory seminar at Harvard — they were more likely to say “stfu” if you ever tried to import that language into a campaign.

But, then I don’t see the issue with Beshear also suggesting that people knock it off.

Yeah. I think it’s uncertain how much this actually sours people on the Democratic Party brand (vs holding substantive positions that are too leftwing), but it’s nonsense to say it “doesn’t happen.”

A lot of people, myself included, have written about youth unemployment over the past year, so it’s worth pointing out that age 20-24 unemployment has plunged over the last 6 months:

New paper in PBR: "Working memory’s pointer system is governed by physical objecthood, not spatiotemporal information"
rdcu.be/fd2tY

Without valid WM pointers, we miss OBVIOUS changes in visible items; the study shows that this "resetting" process is all about objects and not spatiotemporal change!

People in computer science or cognitive science seeing emergent behavior from a simple system treat that as a point in favor of the design of the system being on the right track. The public seems to treat emergent behavior from a simple system as grounds for reductive dismissal.
