When someone says β€žScientists do not want you to knowβ€œ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

I think when we made the bar for acceptable presidential candidate conduct β€œis it legal” we were cooked. We all remember β€œthat makes me smart”
but a society needs norms to function smoothly because it’s simply not possible to codify every corner case into law. Without that it’s a race to the bottom.

β€˜The most bitter news’: Iran reels as more than 80 children reportedly killed in school bombing The building appears to be among many devastated in Trump’s β€˜major combat operations’ as long expected attacks arrive

Amidst this tragedy I can’t help but wonder if this was planned with a cursory intent to avoid civilian casualties and the people at the top were so incurious & lazy they didn’t bother to check and thereby realize a Saturday strike would have the opposite effect.

in my experience if I assume the worst ~20% of posts are either trolling, bots or purposeful garbage from the IRA then the internet seems far more sane than it otherwise would when compared to real life interactions

obviously there are real people with bad takes but my cortisol levels are better 🀷

easy carbs are good for keeping glucose levels up, cycling dorks have been slamming gels on rides forever which are basically adult GoGo Squeeze with more carbs and dextrose but waaaaaay less enjoyable

Why isn’t LA repaving streets? With the city’s budget issues and new paving practices, the potholes and cracks on Los Angeles streets are only expected to worsen. With the city’s budget issues and new paving practices, the potholes...

To avoid including alternative mobility affordances (ADA compliant sidewalks and bike lanes) as mandated by several ballot initiatives with big $$, the city is instead doing a bad job paving roads to exploit some notional loophole in said ballot initiatives.

New Yorkers: if you can do so safely, take a moment to step outside (even on your front stoop) for a moment and appreciate how quiet the city is right now. ❄️

Cities aren't loud. Cars are loud.

It seems the only remaining purpose of the school association in college football is to distinguish it from professional football.

If they get stuck they can fall back to a remote driver to resolve confusion I believe? There was a whole meltdown about this recently.

Random idea for web standards people:

An interesting test of a written standard is an implementation. Since we now seem to be living in a world where prototypes are made quickly (AI) one could request such an implementation and view confused interpretations as an opportunity to clarify.

It also leans in the direction of automated reasoning

> By enforcing invariants … we let agents ship fast without undermining the foundation.

We’ve been yelling about this at work: trust wants structured output and checks via ground truth written in logic with interpretable failures

A lot of it reads like guidelines for how to work in large teams

> In practice, this meant working depth-first: breaking down larger goals into smaller building blocks (design, code, review, test, etc)

Which makes me wonder if the people are getting better at communicating amongst themselves too?

How the GNU C Compiler became the Clippy of cryptography FOSDEM 2026: Security devs forced to hide Boolean logic from overeager optimizer

Ancient Aliens meme:

*verified compilers*

Yah totally, we can make nondeterministic systems correct/ robust. In the case of LLMs that’s a per request/per system proposition but there are other such very complex (inscrutable) translation systems with universal correctness properties (like compilers) which makes this analogy somewhat weak 🀷

09.02.2026 20:13 πŸ‘ 0 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

I think we probably agree. On point 2 one can verify generated programs of course (do the verification too please!) Quite separately I can say once and for all what it means for a compiler to be correct in translating between languages but I can’t do that for LLMs which go from English to code.

09.02.2026 20:05 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

When one needs to understand the build system to answer questions about outcomes that’s significantly easier for deterministic pipelines.

Similarly, I see this same argument made wrt compilers but it is possible to say what a compiler should do to be correct, that’s not true for an LLM.

There’s a substantial portion of the US population that’s having a full mental breakdown right now.

This is almost entirely unrelated to the content of the article.

Whenever UB is discussed I rarely ever hear about the reason why it exists and why it’s good: it’s how the compiler tells you about assumptions it needs for optimizations you almost certainly like a whole bunch.

Best modern example is stacked/tree borrows in Rust unsafe regions.

Buried way way down in that article:

There’s also clearly an interesting opportunity to hook up CSmith in a tight loop with the output here to see how well it responds to feedback about output discrepancies
