3eb7988a1663··on US Revokes Limits on Power Plants' Climate Pollution
You burn a barrel of oil once. A solar panel lasts for 20+ years. After you have installed it, if China announces they will no longer sell new ones - you have two decades of lead time to start building your own domestically.

Or that Germany shares electricity with the EU, so that everyone is getting subjected to those pains with fuel sources being cut.

One thing that I really want to know - the better models from today vs a year ago - what has changed. They have already pre-trained on all available public data. Scooping up the last percentage of archaic texts which were never digitized is not going to move the needle.

Is it just that the providers are generating tons of synthetic datasets on coding tasks so that the models get more exposure to the right thing to do? Every time someone points out an LLM stupidity they add some training data to patch over the weakness (trivial to generate "there are two 'l's in llama")?

Do replay files require consistency or can you spawn new units from the ether as required? I think you could get a system that would get the broad strokes unit placement correct, but having a shot-for-shot perfect replication seems impossible.

Who is offering the refusal vectors or instructions on how to generate them?

Formal agreements matter unless the counter-party is the US who will gleefully alter the deal the second it becomes inconvenient.
3eb7988a1663··on SR-71's "R2-D2" Could Be Key to Winning Future Fights in GPS Denied Environments
Would that hold up in court if the person were willing to challenge it? That seems a clear cut violation of that person's speech, but I guess anything for "national security".

Indeed this is not the article I originally read either, but very similar breakdown of the problem.
3eb7988a1663··on The Return of Sail Power: Cargo Ships Are Turning Back to the Wind
The article did mention suction sails for the Maersk Tankers, but it does seem like the bulk of the article was about the rotating tubes.
3eb7988a1663··on The Return of Sail Power: Cargo Ships Are Turning Back to the Wind
If anyone else was confused why those pictures were of giant tubes and not canvas sails, you are not alone. Apparently those are some version of "Suction Sails". The vendor's website has a graphic that explains it, though it was fighting my ability to scroll.

Significantly larger, yes.

At the conclusion, he said he spent two years on this! That's a thesis.

I am failing to find the article, but some early online poker systems used the server time as the seed coupled with a weak PRNG. With the information of the hole cards + community cards, after a few hands, could quickly determine exactly what seed was being used and perfectly predict everyone's cards.

I can think of at least two people in my career who were, ahem, load bearing for the company. They did all of the BS, non-sexy work required to keep the place running. Never wasted time on vanity projects, just showed up day after day doing the actual necessary things.

They were criminally under appreciated by management. Their career trajectory significantly worse than those who engaged in the highly visible projects.

Skyrim came out in 2011 and is at this moment, the 55th highest player count on Steam. Just playing top tier single player games over the past twenty years could keep you incredibly busy.

That's exactly how it was revealed that a high quality image intentionally leaked by Trump came from a satellite and not an overhead plane.

3eb7988a1663··on Oil Executives Say the Great Fuel Crisis Is Here
From a purely efficiency standpoint, yes, but practically, electricity->heat is a lot cheaper to install. Plumbing is messy, and bolting on a water circulation system to a roof is harder than delivering more joules over the wires.
3eb7988a1663··on Oil Executives Say the Great Fuel Crisis Is Here
Yeah, but the important question is where would Putin be after that?
3eb7988a1663··on Oil Executives Say the Great Fuel Crisis Is Here
Right after you get that DOGE check.
3eb7988a1663··on Data collected by cars and sold to third parties
The systems must be separate if they were able to disable some of the network connectivity but maintain GPS.

I thought GP was talking about if they had to reconnect the systems for some reason, would archived telemetry suddenly be uploaded. Which is a real possibility, so I was suggesting poisoning the data. Even if you correct the clock today, the previously recorded timestamps cannot be automatically fixed. Even better would be to reset the clock on every startup event.

Which is all still a band-aid solution - a targeted analysis could mostly correct the time-keeping. This just prevents getting scooped up in a simple drag net kind of search.

3eb7988a1663··on Global shortage has led to motor oil rationing at Costco
Things are really about to hit the fan. The world has been surviving off of strategic petroleum reserves, but those are quickly hitting the bottom. The US last reported at 285M barrels[0]. There is a legal floor of ~250M, after which it is reserved for government national defense. Usage has been all over the place, but the drawdown has been somewhere in the region of 1M barrels per day. Public analyses have said that the cavern integrity becomes threatened once levels fall below 300M. Current government claims the "real" floor is at 70M, but I believe this is a transparent ploy to assuage markets.

The Saudi pipeline that was attacked had a capacity of 7M barrels per day. Gone for who knows how long. That 7MBPD that needs to come from somewhere.

Edit: Should add - the big tankers require ~month to move oil to most consumers. So, there is one month of breathing room before the new pipeline loss materializes.

3eb7988a1663··on Data collected by cars and sold to third parties
I did say lose the GPS.
3eb7988a1663··on Data collected by cars and sold to third parties
If you are willing to lose GPS, maybe you could set the car's internal clock to the year 2000. This might fool a cursory data dump that is looking for "last three months of driving habits". Would obviously not stand up to any real scrutiny, but mostly painless.
3eb7988a1663··on Libraries Run Rust Inside Python (With PyO3)
The Python cryptography library switched out C for Rust which invalidated some platforms[0]. 2021 story, so not sure if anything has changed.

   ...Since the Gentoo Portage package manager indirectly depends on cryptography, ""we will probably have to entirely drop support for architectures that are not supported by Rust"". He listed five architectures that are not supported by upstream Rust (alpha, hppa, ia64, m68k, and s390) and an additional five that are supported but do not have Gentoo Rust packages (mips, 32-bit ppc, sparc, s390x, and riscv).

3eb7988a1663··on David Sacks: OpenAI and Anthropic Don't Need Regulations to Pace Frontier Models
The Houthis missile story coming out now also feels like convenient fuel for the fire.
3eb7988a1663··on Houthis used Claude Code to develop missile guidance software: Anthropic
The isolation was so good, many of the workers had no idea what they were doing. Interviews after the war with the rank and file contained quite varied speculation on what the plants were trying to accomplish. I remember one nurse who thought it was all just a cover to get blood samples.

IT tech was probably the one who suggested the approach.
3eb7988a1663··on Linux Zoom client proactively reading everything written to X11 clipboard
Well this was back in COVID, sometime fresh after the always-open-port news had surfaced. Can easily believe the experience has been improved since then.
3eb7988a1663··on Houthis used Claude Code to develop missile guidance software: Anthropic
What is more difficult, building a military missile or the software that runs it? If they are already building weapons, not sure the software to run them was the impediment.

Presumably, the world used dumb munitions without any software for a long time.

3eb7988a1663··on Vintage Scientific Papers with LaTeX
Heh, I read the title and thought this was going to be about someone porting legacy publications into Latex code. Anything from Newton's gravity to Marie Curie radium.

Which would be nice - some seminal publications from not all that long ago are only available as terrible quality scans.
