PowerElectronix··on French digital tax may kill VideoLan non-profit
Social spending, by a lot, even though only a 5% cut would set the budgets right.

I bet they can also cut a lot of politicians and designated positions, but I'm not that deluded to think they would.

PowerElectronix··on How do you take a picture of a black hole?
Well, at some point space-time warps so much that unless you are at the center of the would-be singularity, you'd see everything closer to it than you freeze-out as an event horizon appears. If you are inside the event horizon then... I'm clueless about what you'd experience.

If I to guess, you'd see yourself outside an smaller event horizon (as nothing gets through one due to spacetime warping) and you's have a lot of mass very far behind you due again to space time warping so that yout local scape velocity is less than c.

PowerElectronix··on How do you take a picture of a black hole?
I can't think of a way of getting a singularity. As soon as the mass in a region of space becomes high enough to start a black hole, time would freeze and it would take several millions universe lifetimes for the mass to fully collapse into itself, no matter how close of far the observer is to the mass. The way I see it, things would go on as usual inside the black hole, but there's a universal curtain preventing anyone from accessing the interior.

They will tax everyone for everything before they even contemplate controlling their spending.

PowerElectronix··on What we know so far about Spain train crash
In spain the procedure calls for driving by sight. There was a third train coming that stopped because the driver ignored the command to drive at normal speed and drove by sight.

The real issue is that the LZB fails often enough (installed back in 1992 and due for a phased out in favor of a newer system last year with the contract awarded and no work yet started) that the only safety assurance is the person at the command center issuing command flawlessly, which is not sustainable as it can be seen.

Iryo CEO said a few weeks back on a congress hearing that every time the LZB goes out, their trains are completely stopped. This must have slipped the central command resposible's mind as it was ordered to everyone to just restart the march, but the Iryo just couldn't.

PowerElectronix··on Alleged Chinese spy had 'close relationship' with Nvidia boss Jensen Huang
The honeypots are 100% the best part of being a spy or a VIP target for an intelligence agency.

On that note, they never worked on french spies as infidelity and sex stuff hold seemingly zero leverage over french men.

PowerElectronix··on Are stochastic parrots alive?
Is this asking if they're a living being? Because they're clearly not. If this is trying to ask if they have a consciousness, then again the answer is not.

Shuffle the pages of a dictionary according to some rules and you got yourself, according to the author, a living being.

PowerElectronix··on Why birds can fly over Mount Everest (2020)
I loved the article. I knew already about fungi taking millions of years to develop a mechanism to eat wood, but the ramifications into dinos getting huge due to their superior breathing systems was a completely new to me. I thought everyone had lungs on earth!
PowerElectronix··on Valve Responds to Developers Fearing AI Slop and Clones
Not in the least. You can make a 2D platformer and Nintendo can't sue you for copying Super Mario (they'd like to, probably).

The only defense against copies has always be the same, be better than the copies in thing the consumer likes. You can't copy a Mario game, you can't copy a Kojima game, you can't copy a game that has been masterfully done and polished. If slop is gonna eat your lunch, it's only because your game is as good as slop.

PowerElectronix··on The Grid, a factory-scale robot in Massachusetts that builds PCBs on demand
Great news, wish you all the best. I just wish the PCB sizes could stretch a bit to 330mm by 330mm.
PowerElectronix··on Wealth Inequality in America drawn to scale
Or educate, promote or even mandate that a share of a company must be given to the employees of said company.

If you "fool" a hundred thousand individuals to work for a company on a wage and through their work the company ends up been valued at a billion, you become a billionaire. Wouldn't they deserve a bigger cut of the fruit of their labor?

The fastest way to distribute wealth isn't taxes on wealth, it's a better distribution of the wealth generated by labor on the contract that the employee signs.

Outstanding observation.

PowerElectronix··on Superhuman Hardware Design Is the Easy Part
I say that hardware design has a way bigger solution space.

In chess, being able to check hundreds of lines per second makes you a superhuman. But in hardware design you get lost if you try to search the solution space for a circuit, schematic, component selection, layout, routing, stiffener and thermal solution.

There are a few like positioning and routing where the solution space can just be considered infinite as there are infinite copper geometries (even if you stick with straight line polygons) that can connect a number of infinitely differently positioned components.

Then, for the mechanical stiffener, again you have an infinite number of geometries that don't clash with your components, don't run over your copper traces and make the board resist the mechanical tests (which the AI could check with a lengthy FEM analysis per iteration).

After all that, or in parallel with the mechanical analysis you can run the thermal ones and tweak positions of the hot stuff and thickness of stiffener walls to get everything fine.

I just can't see an LLM do that with a board with a few hundred components, even if most are decoupling capacitors.

PowerElectronix··on US designates helium as a critical material
Oh no! My Helium!!

C'mon... First, there's no infrastructure in the US to process the gas and purify to semi manufacturing levels. Second, as soon as the epstein war is done (either by Iran allowing navigation through Hormuz or the arab countries developing alternative routes), Helium orices will go back to be so low it doesn't make financial sense to purify unless you have the volumes they have. And by then, still no infrastructure would be ready for the task.

PowerElectronix··on Superhuman Hardware Design Is the Easy Part
A lot of stuff one learn along the way never gets put formally on a document, and every iteration has to be checked in the lab.

With code or math or simple text, or games, you can have swaths of documents easy to digest and readily available, you can run thousands of tests per second and you can check results right a way.

With a power converter, a ddr4 module, an fpga, you have to build the pcb, assemble it, test stuff little by little, fix thing as they break, increase power, etc.

You can take notes on stuff that has been changed , the reason for the change is usually a few words note if any. And then you find something weird and you see that there is absolutely nothing on internet about it and you have to find out on your own. At least that's my experience with hardware design.

For the important stuff that makes you lose a board or a month of work you make sure to document the reason and the solution, but it usually is in a internal document no one will (regretably) read.

If you then add mechanical stuff, thermal management, failure modes, etc. I just don't think there's enough compute power to bruteforce such a huge space of solutions, even if you don't take into account that you can't really teach the machine about hardware design apart from some open source stuff and development kits where documentation, part lists and gerbers for the pcb are available.

PowerElectronix··on Superhuman Hardware Design Is the Easy Part
You would beat anyone if you could calculate a few thousands moves per second, even more so if you had a neural network that discards suboptimal moves early.

Disclaimer for stockfish in particular: Even if it's mostly bruteforce nowadays, stockfish usually has an edge because it can bruteforce with "taste" and can manage the clock very well knowing when to ponder deeper a position.

PowerElectronix··on Superhuman Hardware Design Is the Easy Part
I have to disagree here. While it's been proven that a lot of things can be done by just searching a very big solution space very fast (either by brute compute or by a sophisticated algo or both), hardware solution spaces are not that easily searched.

For a lot of applications where signal integrity is not critical, high frequency switching is not required and power density is moderate, yeah. Anyone can do that, even an AI. But you don't even need to make a pcb for those cases, just throw the components in a protoboard and fire away.

When you start adding variables to the search space (emi interference, matching routing impedances, heat management, mechanical integrity, etc) the search space grows so big that any non-expert will become lost in it.

Will future cheap compute power be able to overcome this? I'm not betting on it.

PowerElectronix··on Demographic "doomsday" misses the mark
It 100% is. Even thought there are parts that feel like reading different molecules and formulations out of a chemistry books for pages at times, it is generally very good in giving you a sense of how different (and similar) the engineering job was back in the day. Also, the dark humor is the cherry on top (and a necessity for those working with those chemicals, I imagine)
