Comment TF are these toasters *doing*? (Score 1) 53

Every time they talk about this damn thing it's a different size and works by a different mechanism. Explanations given vary from this magnetic field mumbo jumbo to essentially just being a near perfect dead reckoning integrator.

Anyone have links to any actual papers or journalism on the subject that hasnt been oversimplified to the point where it is just nonsense?

Comment Why on Earth would you EVER announce it? (Score 1) 49

If/when true AGI is achieved, only a fool would announce it. What would announcing it do for you? Make you famous? Rich? Cool. Know what's better than all that?

Not telling a damn soul and using the AGI quietly to do whatever the Hell you want. If you want to be rich, the AGI will tell you how to become rich. If you want to be famous, the AGI will tell you how to become famous. You can do both. And you don't have to stop there. A real, vastly superior AGI enables the person controlling it to do anything. The second you tell people about it, you'll lose control over it and then you're the famous idiot who did a cool thing one time. Kids in elementary school will recite your name back on a test. And you could have had everything.

Anyone smart enough to crack AGI can't also be stupid enough to advertise when they do it.

Comment Re:It is low CO2 (Score 5, Insightful) 135

You can get a lot more renewable energy for the money. Colorado tax payers are going to get fleeced by this.

The other issue not mentioned is speed. It takes so long to build nuclear that it can't be part of any realistic plan to address climate change, and it also makes it very prone to corruption because nothing gets delivered for decades.

These are all issues directly related to regulation and unnecessary red tape created out of NIMBYism and irrational fear around radiation. India, Canada, and China aren't stupid. They're building and/or modernizing nuclear power plants like crazy because they're so effective at reliable baseline power, which renewables simply are not. In the US, we force years - sometimes decades - of reviews and permits and defending court cases and other bullshit unrelated to the construction and operation of clean, safe nuclear power.

The other issue going to cost is that the US - again, stupidly - bars reuse of high energy spent fuel. If you simply separate the low energy (relatively safe, but useless for generating power) waste from the high energy fuel remaining and feed the high energy stuff back in, you can extract nearly all the energy, save a ton of fuel costs, mine less fuel, and have vastly less volume of waste and vastly less energetic waste.

Let's assume some sort of absolute mandate were passed to build 5 CANDU-6 (known, proven, safe, reliable design) reactors. No reviews, no permits, no red tape, no lawsuits. Just build the damn things now. You can get one operational in ~3.5 years, all of them in about 4ish years. South Korea and China have built PWRs in 5. Assuming we also lifted the ban on fuel reprocessing, CANDU-6 plants will produce power at a cost of 5-6 cents per kWh, yielding a retail price of 13-17 cents per kWh. US average is about 16.2 cents, California has rates pushing 50 cents. But we're too stupid to get out of our own way and just do it, so we'll keep strangling the poor and middle class economically.

Comment Brute force approach (Score 1) 154

It's clear the brute force approach works and is sometimes the best way to advance. Once you see the path to getting the job done, take it. I see projects like ITER and ChatGPT4 in this category. Can you learn to do these things more efficiently given a few extra years of R&D? Obviously. But you are also a few years behind, and you have probably spent a lot of effort prematurely optimizing.

Comment The color of LEDs (Score 5, Informative) 124

Gas tube signs have a very unique spectral emissions that makes them appear the way they do. Very little effort has been put into LED lighting to properly mimic the appealing spectral emission of incandescent filtered or gas tube colored lighting.

Almost exclusively phosphor coatings have been tuned to cause blue and near UV leds to emit (sort of) broad spectrum white light and nothing more, though it would certainly be possible to develop a phosphor that could more closely approxmiate neon, for instance.

As for direct emission, red green and blue LEDs are mostly now only available at certain wavelengths for tricolor mixing applications. Due to economies of scale, LEDs at other visible wavelengths are extremely underdeveloped technology.

Comment Re:Copper is good enough... really. (Score 1) 66

You are very enthusiastic, but you have forgotten about critical current. The more current you put down a superconductor, the higher the magnetic flux. At a certain level, the magnetism will disrupt the material's ability to form cooper pairs. In most superconducting materials the critical current is quite low, which is why things like MRI magnets and ITER magnets have historically needed to be very very big. Only very recent advancements in state of the art superconductors like REBCO tapes are finally achieving critical currents that touch the lower end of what is needed for grid-scale transmission. My point is this isn't so clear cut; the materials and systems still need lots of additional development to become broadly useful in these applications.

Comment Goldfish brain (Score 1) 278

If you have access to be able to call up Trump, you call him and tell him what you want. You call him as much as he will talk to you. You'd be absolutely stupid not to do it. The guy has the memory of a goldfish; if you have talked to him in the last day, you are his whole world. After a week, he doesn't even know who you are.

Comment Your payment processor is not a bank! Surprise! (Score 4, Insightful) 14

I cannot imagine a more business destroying move than to be a payment processor that collects money from the customer and stiffs the vendor.

It's not even possible to do this in the current us regulatory environment unless your business is doing some horribly shady shit like comingling customer funds with operating accounts.

Imagine if one day Visa just said, oh we are gonna keep the funds from these 750 million daily transactions to ourselves for 3+ months.

Comment Re:OpenAI was already a dubious idea (Score 1) 35

Bingo. Anybody can think of the obvious. If it's a good idea: a product or service people actually WANT, then a thousand, a million people will have also thought of it. By the time you get to me with your stupid napkin, I'll have a list together of all the other people who got to it first.

Back when I was a startup tech consultant, I wouldn't even meet with anyone who didn't have a proper written business plan. I didn't necessarily care to read it, but if you couldn't make the effort to understand your own path forward, you were gonna be a nightmare client. Despite this being an apparently low bar, it worked very well to weed out the people who overvalued their ideas/contributions.

Comment Phrasing (Score 1) 217

> higher propensity to share low-quality news

For anyone reading along, this is just a euphemism of people with low intelligence. It's not as if propensity to share low quality news is some kind of innate human trait that some people have and some people don't. The issue, depending on your perspective is either: 1) people who cannot tell that it is low quality in the first place or 2) a failure of the media's implicit social contract to report truthfully and without bias.
