Also, would those 550k Blackwell have good FP64 performance? How would one even compare them?

I want to say I really appreciate that you are putting a lot of thought into this, you certainly have interesting concepts here. However I think it seems a bit far off from the discussion I'm trying to have, and I do not have the bandwidth to fully understand and charitably respond to your points.

Stablecoins. The statute is the GENIUS Act, and the 'opaque companies' are Tether and Circle holding the reserves that back the dollars people in high-inflation countries actually use. The tokens themselves are boring, what's unaudited is whether the t-bills behind them are really there in the amounts claimed.

We don't know what thinking is but pattern matching is definitely a big part of it. That's why people see Jesus on a piece of burnt toast.

Yeah I think the OP is muddling the point by conflating "physician's version of the diagnosis" with "The Diagnosis".

There is absolutely one "The Diagnosis". Human body is a machine, albeit a very complex one, and all measurement sources have noise. But they are all measuring one reality, and if there is a problem, there should be one explanation that all measurements align with. They can be noisy but can never be conflicting (instrument error notwithstanding).

Physicians' ability to arrive at "The Diagnosis" would vary, but it does not mean one does not exist. I am not sure if characterizing human body as derministic or not is relevant here.

It was a social panic. AI PR convinced tech execs that companies who didn’t adopt AI as a significant part of their workforce would fall behind (and in capitalism that means they lost market share and revenue). Investors likely put pressure on execs to do this in addition to the AI PR campaigns. FOMO is chasing the carrot you see everyone else getting, but this was more like chasing the thing that supposedly deters the stick.

It’s also worth mentioning that it still might be the right business strategy for some companies / industries. We are only 3 years into the revolution of AI for business processes and in previous revolutions there were riots, sabotage efforts, factories still being created in the style of the previous revolution, etc.

Not having literal strings in the source code, I do need to get a capital “R” somewhere and the name of the system being “IRIS” in system variable $ZV makes that easy and terse. Apart from that one trick I think it’ll be more or less just fine.

This is what Stephen Colbert called "truthiness". People want to believe what they feel is true even if it is directly contradicted by evidence.

Same. Ironic that a quirk of modern technology would put classical literature back in fashion.

Ensuring integrity definitely requires in person proctored exam centers. It does not require hand written exams.

Hand written exams are either very labor intensive to grade or are confined to multiple choice, so either inflationary to cost of education or inauthentic / inaccurate representation of most knowledge and skills.

The best answer, which enables authentic meaningful high integrity assessment that is also unit cost efficient is to have testing center facilities with institution supplied devices and well trained proctors.

This way instructors can assess students in ways that are relevant and authentic to the subject matter while ensuring the assessments are accurate, consistent, fair and actually reflect the students abilities.

It is more intensive and aesthetic but functionally I believe it’s exactly the same.

Yeah, the current admin is reactionary, they appear to put little thought in, or at least disregard input they dislike. I don't think Ant's ban was about "owning the libs" as much as it was asserting dominance over someone who spoke up counter to the admin's aims and claims. They do listen to money, which is where I see Big Ai paying for executive orders (because the admin forgot what it means to compromise as part of legislating for all americans).

The gray beards were always least threatened by AI. It’s the junior market that’s getting decimated.

New comment by aftbit in "What is a Lithium-ion capacitor?"

aftbit — Sun, 28 Jun 2026 21:15:01 +0000

That wouldn't have contributed much to the discussion. Electrical insights often come from analogies. It's easier for most people to understand time derivatives in the context of an accelerating car than it is to understand them in the context of a capacitor or inductor charging.

Another cool insight is around "dual" relationships in circuits. You can often think of some components as roughly analogous to each other, with a switch of current and voltage. For example, if you connect a capacitor in parallel with a power supply and load, the voltage across it will increase as a function of time until it reaches the power supply voltage. Similarly, if you connect an inductor in series with a power supply and load, the current through it will increase as a function of time until it reaches the current that would otherwise pass through the load.

Like most good analogies, it's not 100% airtight, but it provides useful insights.

They don't have the political will because doing (1) and (2) would result in the removal of whatever politicians approved it.

I was about to link to the same "What's on the Menu" site, which I remembered being an impressive site for library digitization project years ago, but it was apparently retired in January 2025.

Now [1] redirects to [2], essentially an About page with links to the data.

I often ask, usually Gemini, at a medium abstraction level (not general What the diagnosis is, neither specific like What this high serum Ca means). The answers are correct but not enough and ready for consumption without doctor guidance.

A cardiologist friend goes in deep discussions with a specialised model and he is amazed.

This article is mostly AI slop. It’s very recognizable, and that’s probably what you’re picking up on in other articles as well, because it’s everywhere right now.
