The headline says "sold out". That doesn't mean prices will go up, that means the memory will not be available at all for many companies and the products they make will not be available to consumers.

There's some clarification here, see the editors note at the end: https://pv-magazine-usa.com/2026/07/28/fcc-bans-foreign-prod... So there won't be an immediate impact on solar inverters, but there

Note that they also banned Chinese inverters at the same time. Industrial inverters are still made in the US but solar inverters are often made in China. So is this an attack on home solar and solar farms?

So do incinerating satellites create tunnels of conductive plasma through the atmosphere? Perhaps they are creating short circuits in the air. Could pieces of junk reaching the lower atmosphere cause lightning strikes by creating conducti

So this looks broad enough that it should apply to online retailers like Amazon also.

Doesn't this mean such data analysis can be used by anyone against anyone else? This does not just mean one political group can do this analysis, any political group or foreign power can make use of the data if it is not protected usi

Perhaps these trades are the result of a national security compromise. The current administration has reducing spending on cybersecurity, so perhaps Trump's own phone has been compromised and a foreign country is using the information

This seems like a prototype for AI malware. Given that an AI agent could run anywhere in a vendors cloud it makes it very similar to a computer worm that can jump from machine to machine to spread itself and hide from administrators while

So what is happening right now with rare earths used for military purposes? My reading says it will take 5-10 years to build processing facilities without which the raw ore is useless. Has the US stopped building missiles and fighter jets

While I do hoard notes I've realized over the years that the main reason I write notes is as a memory aid. If I write it down I remember it better, and I'm more likely to do it. Notes also act as a filter because I write stuff d

Is the root of the problem buying more power or building more grid?

There may be a more subtle issue here. When the specification is interpreted by an LLM that is different than it being interpreted by a person. From the LLM you get a kind of average of how a lot of people wrote that "kind" of

How does many worlds justify the doubling of energy with each quantum split? Probability can double all the energy in existence for every quantum fluctuation? Is energy conserved between realities? If not, that makes reality a very stran

Not everyone sees color exactly the same way, for example some people can see a little into the IR and UV. While the pilots may not be colorblind, the people who repair the displays might be. Situations can also make pilots colorblind, li

Yes, it was supposed to be an alternative graphic for a cockpit radar display in a jet fighter. The goal for any such display is to convey maximum information at a glance. I got feedback from a fighter pilot who said he wouldn't use

Cool, I tried something similar 30 years ago working for a military contractor: http://zoom.interoscitor.com/PetersonEnterprises/Consulting/... I was asked to come up with a 3D display of the airspace around an ai

What is perhaps more important is how this transition will be managed. Are the old methods just being halted and all projects halted and the new methods will take over whenever they start producing products? Switching horses midstream cou

These are their alternatives: What neither Big Tech nor Big Media will say is that stronger antitrust rules and enforcement would be a much better solution. What’s more, looking beyond copyright future-proofs the protections. Stronger envi

They don't seem to have considered fungus spores as PM2.5 either. Seems like a single spore could cause more damage than many carbon particles.

This group has had some success turning machine learning algorithms into low power analog chips: https://sites.dartmouth.edu/odame/ Not the same as general purpose training type computations though.

If this is being recognized as a systemic problem should not the government step in and regulate? Why do they have to wait until after a crash to do anything? Just a statement that there will be no bailout could moderate behavior.

Can't anyone use AI to surveil social media, even ordinary citizens? It seems like it would be easy to surveil ICE, the police, immigrants, all politicians, the military, businesses, government, individuals, groups, anyone and anythin

Rare earths are not rare on Earth, but production of rare earth metals is rare and difficult and almost exclusively done by China. There are two other factors that make this announcement important though. One is the use of the foreign dir

If these strikes really are hitting drug gangs, I would expect the gangs to strike back, just as they do when they attack each other. They already have people in the USA, and they would have no problems with attacking civilians or politici

Isn't the training most of the cost? In which case the current models could have a very long lifetime even if new models are never trained again. They'll go gradually out of date, but for many purposes will still be useful. If

One potential application might be fighting wildfires. Seems like it would be really useful if one firefighter could remotely monitor a dozen autonomous bulldozers that were given general instructions. Would have to acquire a different tr
