There's basically no point. Desktop PSU is a solved problem, most designs are all about cost engineering and the tiny sliver of higher power and ultra high efficiency options are not struggling with their current form factor. In the da

Well, kinda. The value is in meeting the spec, yes, but the "certifiable" part is very often a subset of the actual spec. Sort of like in software how someone will inevitably depend on every feature of a public API (including the

I wouldn't be so quick to make guarantees. There's cheaper spec-equivalent devices, sure, but a frequent and recurring feature of military hardware prior to the 2000s is an unexpected dependence on non-spec device characteristics.

Suppose an asteroid strikes the Earth and all human life becomes extinct. What power, specifically, has been transferred, and to where?

I think the question was less about the efficacy of ABS, and more about the failure mode. Is it possible for the ABS system to "fail open" unintentionally, such that depressing the brake pedal has no effect whatsoever?

My employer blocks access to Google Docs as part of our confidential information protection policy. They're certainly not the only ones. I'd hesitate to call on-premises file management "specialized needs" - rather, it&#

Historically this was a huge concern because not every manufacturer implemented their ESD protection properly; or, on occasion, the process technology meant that ESD protection would hinder the functionality of the device. This happened a l

These parts are bonkers. The ringing on its own outputs with a few inches of trace or (heaven forbid) a connector is regularly sufficient to self-trigger the automatic direction reversal. These things genuinely deserve the "experts onl

Learned a few tricks that I'm sure are buried on fstring.help somewhere (^ for centering, # for 0x/0b/0o prefixes, !a for ascii). I missed the nested f-strings question, because I've been stuck with 3.11 rules, where nes

Because, unlike most professions, ATC is immediately, personally responsible for making decisions for which a slight mistake could instantly claim the lives of hundreds of people.

Which language is this? I'm sure some people can clue this together from the hints, but I'm not one of them.

For what it's worth, this post just helped me explain several years of failure to wake from sleep state, across several different MSI-based machines, when I've connected them to an HDMI port in my TV. I think this debug is interes

As someone with a hardware background, I'll throw in my $0.02. The schematic capture elements to connect up large blocks of HDL with a ton of I/O going everywhere are one of the few applications of visual programming that I like.

A lot of these environments inherit a visual presentation style (ladder logic) that comes from the pre-computer era, and that works extremely well for electrical schematics when conveying asynchronous conditional behaviors to anyone, even p

For Uno specifically: I do like the attempt to build out a WASM target, it looks usable. Uno looks to be in a lot better state internally than even two years ago, which is promising - that's one thing I can't get out of either WPF

If Microsoft said "Windows-only, good luck with cross platform," I'd accept it and move on. It's their prerogative to spend their resources enhancing their own platform. Instead, I've been told a half-dozen times th

Presumably because, much like the half-dozen other flexible cross-platform frameworks Microsoft and friends have gotten one-third of the way to a viable product before abandoning to chase the next shiny thing, it's riddled with bugs, a

This is frankly infeasible. Between the decades of trade secrets they would first need to discover, the tens- or maybe hundreds- of billions in capital needed to build their very first leading edge fab, the decade or two it would take for a

I don't agree with the premise. Integrated circuit manufacturing scales well because the cost per transistor is lower with every process improvement, so as process improvements accumulate, more value (or perhaps more productivity) per

With Cloud, as long as you don't mind solving the same problem multiple times every few years when things you depend on go obsolete, indeed it is a nice experience. A lot of people do mind. I won't belabor the point; Steve Yegge s

The US literally stopped issuing new reactor permits in 1979 (down from on-average about 12 per year), and didn't begin issuing new ones until 2012. Out of 177 reactors issued construction permits up through 1979, at most 112 were ever

IronPython is indeed quite a pain to work with, and for a lot of reasons beyond the age. For instance, you don't get numpy or any dependencies that themselves depend on quirks of CPython. The alternative is PythonNET, which executes py

You're already seeing it. Xilinx led the industry in chip interconnect technology, SERDES, MCMs, die stacking... they've been making chiplet designs since 2011. They were the ones inventing all the interconnect and packaging techn

Shorting the inductor temporarily converts some of the energy in the stored electric field of the input capacitor to "stored" magnetic field in the inductor (not quite, since it's only present when current is flowing, but clo

I'll agree that it's largely a semantic difference and that I overstated the significance of the MOSFET involvement as the pass element - you can design single-transistor PNP elements with only a few hundred millivolts dropout, an

I think the big driver for solar inverters was panel cost reductions. With motor drives it's straightforward even 25 years ago to see the benefits and applications of slapping a DSP and some digitizing sensors onto the system to do cra

Maybe 300mA order of magnitude is more common than 3A, but it's not inconceivable. Lots of designs wake up, burst some RF data at a few hundred mA transceiver load for a few tens of microseconds, then go back to sleep for another few s

Sure, direction of current in the magnetics does capture the intended distinction better. Ripple currents are usually non-ideal behavior, and cases where it isn't (discontinuous conduction mode in the boost converter) are probably argu
