PowerElectronix··on There's never been a better time to go into math (by: 3blue1brown) [video]
IF (very big if) you could have access to all known variables (with an arbitrarily high precision) and enough compute power AND the system was deterministic, you could very well deduce it. Putting some quantum noise in the mix makes it so no matter how well you know the system and compute it, you can't predict its behavior beyond a certain hard limit.

I argue that part of the source of quantum noise is baked in already in the finer workings of the neurons. So a mathematian isn't condemended to be one just because the universe was in certain configuration a few millenia ago.

I'd say it's the other way around where quantum effects introduce noise in the brain working that makes the system non-deterministic.
PowerElectronix··on How Quickly Can the DoD Rebuild and Recast the Munitions Industrial Base?
You can lower costs by a lot dropping some requirements like component deratings, screening, temperature of operation, mean time between failures rate, etc.

You end up with a _just as good_ device that will fail way more times than before (1:100 or more instead of 1:100000) but is way cheaper and way easier to procure. When it fails just launch another.

I wouldn't specifically do this to the tomahawk as it's used in missions where accuracy is critical in order to avoid collateral damage. But otherwise I'm a strong proponent of applying "new space" logic to military gear.

Synapses in the brain are affected by quantum effects that lower or increase the threshold for firing. Thus they are not deterministic and people do indeed have influence over their own behavior.
PowerElectronix··on Laser Fault Injection on a Budget: RP2350 Edition
The GaN hemt would make sense for a second board iteration where you drive the 75V straight through the diode with a very short (variable) pulse like in this EPC reference design:

https://epc-co.com/epc/products/evaluation-boards/epc9172

That way the 1.4 Ohm resistor doesn't eat like 60-80% of the energy (40amps drop around 60V for an instant 240W in the resistor vs the foward voltage of the diode which is like 1.5V or so for the 60W peak).

PowerElectronix··on Gold is now the top U.S. export
Speaks volumes of the results the policies to make the US a manufacturing and exporting country are getting.
PowerElectronix··on Amazon uses AI to monitor union risk in UK warehouses
This has nothing to do with capitalism, as these practices antagonise paying customers and quality employees and will lose money to the company in the long run.

This has all to do with people wanting control over other people, which may me classified under authoritarism, totalitarism and the such.

PowerElectronix··on Is Liquid Metal Killing Our PCs? Scientific Analysis and a 2-Year Test [video]
They also sell liquid metal under the conductonaut line.

I thought ptm was all the rage anyway as it can't pump out and is very very long lasting, but I'm probably outdated in that respect.

PowerElectronix··on AI-assisted PCB design for KiCad 10
As a HW engineer, nah. No autoroute nor AI is yet even close to do stuff well in PCB design.

This reminds me of the time Elon Musk was only known because of the supercool stuff his companies did.

Found the psycho that tries to blend in just a little bit too much.

PowerElectronix··on Market selloff, rising rates test AI data centre deal boom
The way I see it it's the other way around, rates need to be raised to adjust to the situation. If the actual yield of treasuries is higher than the rates set by the fed due to AI bonds flooding the market and investors requiring more pay from countries running a 5% deficit While in a boom cycle AND strong economy AND high inflation both with and without energy and food in the accounting then the fed just has to hike to not lose their credibility.

Now, I don't expect them to hike too much beyond what the markets price 1-2yr bonds at, that would, like you say do nothing as a lot of inflation comes from the oil disruption.

Looks like this time wasn't different after all.

As the other comment answered, if a crash materializes like the ones before (dotcom bubble, crypto crash, etc) you'd be able to get a lor of ram and a couple of high end GPUs (5090, 4090 and the like) for a grand or two. With that you can a pretty beefy model locally.
PowerElectronix··on America didn't lose its rare earth industry, it sold it
Everyone wants those jobs, it's just that only delevoped countries can have them in numbers. What I whine about is wanting the low-skill jobs back from the developing countries.
PowerElectronix··on America didn't lose its rare earth industry, it sold it
There's no monopoly at all in the US. But the US society has tools at its disposal that make high qualification jobs possible (high end tooling, high end education with a high output of graduates per year, etc).

A highe % of the population can work in high qualification jobs, but the society will also always need cleks, bakers, taxi drivers, etc.

The effects that high qualification jobs have, with the higher value added to products and services, permeates all of society with higher wages than in other countries.

PowerElectronix··on America didn't lose its rare earth industry, it sold it
Not forever, soon enough (or even right now, actually) China will be developed enough that it'll make economic sense to outsource manufacturing of certain goods to other developing countries.

although it seems that the CCP has a problem with this and expects to be the manufacturing hub of the world forever.

PowerElectronix··on America didn't lose its rare earth industry, it sold it
It works fine for the most part, we have cheap chips (not right now, though) cheap parts of cars, cheap TVs, etc. That are manufactured in developing countries (helping them develop in the process) and designed in developed countries (where only this stuff is possible to design).

It just breaks down when bad actors go against reason for long enough, but the market also corrects for that changing supply chains.

Not a quick buck, it's just so much cheaper to have them manufacture magnets and us the cool stuff, plus the other way around would be pretty hard to pull off.

Right now it's what's propelling corning's price, same as in the dot com bubble.

They can have a pretty good LLM running in there, or cad design. For the average joe, having the free tier of AI without the breach of privacy is pretty good already.
PowerElectronix··on Banks are now trying to offload the AI data center debt they just underwrote
My chop block list has those, plus micron, amd, nvidia, sandisk, western digital, skhynix, corning and marvell.

Those should really eat a lot of shit if any of the two ai companies stops buying everything no matter the price.

In a grown up world with grown ups ruling countries and acting rationally, this would just be efficiency increase in the markets.

The US do high qualification job like engineering design, state of the art manufacturing and the such and other countries go to manufacture nuts, bolts and magnets that are mainly low qualification jobs for cheap.

But, we don't live in that world and the magnet dudes wanna wield the magnets against us and the high quali jobs dudes somehow wanna go back to making nuts and bolts.

PowerElectronix··on Container ship sinks in Strait of Hormuz as Iran steps up attacks
Oh, no, it is way too late for that. The strait is closed if we stay, it's closed if we leave, it's just closed forever for everyone that doesn't wanna be attacked or pays the toll to Iran.

This war has shown everyone that it is just too easy to keep a major navigation route closed with drones and mines.

PowerElectronix··on Container ship sinks in Strait of Hormuz as Iran steps up attacks
War crimes are bad, that goes without saying. And this is probably a bit too much even for Iran. But the only card they have left to play is to keep Hormuz closed to inflicy pain in arab countries and the US, and they are going to play it as hard as they can.

What I mean is that this situation was very predictable and very avoidable by just not going all in in an air campaign with an open ended objective.

PowerElectronix··on ASML's strong orders ease fears AI spending boom is running out of steam
Aren't they always selling everything they manufacture? No matter if you are in a boom or a bust, ASML will always have a years long backlog.
PowerElectronix··on How many shots are in the average movie today?
The thing with longer, steady and uncut shots is that the actor has to know how to fight, move, etc otherwise it stops looking like Jason Bourne fighting and starts looking like Matt Damon acting.

That's why older movies just went with a shaky camera and a lot of cuts in a fight scene and have the scene in a take or two, and more modern ones prefer to go all in in training, choreography and long takes and show you what a good production can look like. I personally thank Tarantino for helping bring that kind of cinema from asia.

Also, if you like that stuff, I can't finish this comment without referencing this masterpiece: https://m.youtube.com/watch?v=Bqw369ZskMk

PowerElectronix··on The baffling intelligence of a single cell (2024)
I'd say it's more to do with the scale of the system than with the underlying working systems. If you get a neuron that fires on a certain signal threshold and with that control an actuator, I wouldn't call that intelligence, just signal processing.

If you have a trillion neurons, some doing basinc control stuff like the one before, with others forming systems that tweak or reroute the others depending on other, emergent potentials, then you have intelligence.

If the brain activity stops being only external information driven and starts being internal information driven (this is, it can change how it regulates stuff o even the stuff it regulates, at different levels of consciousness) then we start talking about something more than information processing.

PowerElectronix··on The baffling intelligence of a single cell (2024)
It's a very smart cell, all be said.
