I've used it to record oscilloscope captures. Especially useful since audio cards are cheap high res adc's.

Offset curves are painful. Farouki et al suggest using a restricted subset of polynomials that are easy to work with. I ran into them when trying to get a constant-speed (arc length) parametrization of splines. https://faculty.en

They lack a bunch of emissions control equipment like fuel injection, catalytic converters, and the like. They are 60's or maybe 80's car engines that are still made since nobody in GA wants to pay for better ones.

Interesting that branch was chosen over CMOV in the ToString bool case, it's a PGO case study: https://discourse.llvm.org/t/rfc-cmov-vs-branch-optimization...

Changing from a clearinghouse net once a day settlement to real time gross settlement is a huge change especially if you are a small bank running ancient software.

Regulation E limits liability for fraud. ACH isn't an anonymous system either.

If you are using so much bandwidth on a gigabit line that the buffers are actually used, I'd think you probably want a higher grade of service than home internet.

Yes, true. But at that point you have to run on exotic 4p/8p systems since you start running out of memory channels. 256GB DIMMs go for ~3k, so 133k for just 1TB is still a bit much.

That's insanely overpriced. A 128gb lrdimm is $1000. So a tb on a commodity 8 mem slot board would be 8k plus a few thousand for the cpu and chassis.

Twice the voltage = half the current for the same power, and 1/4 the resistive losses in the wiring.

We can trace the dependency on gas to Germany's ill advised policy to go all in on coal & gas after shutting down nuclear. Other countries now have an enormous economy entering the market, driving up prices and effectively controll

Bingo. This is why they loved the ACA. Only allowed one scoop of ice cream? Great I'll use an enormous scoop.

And? It's Congress' job to make policy and pass laws. They can and should take advice but the whole point of democracy is that the policymakers are democratically accountable.

Mathematics has known about solitons since 1844. I thought it was well known that rogue waves are Peregrine solitons? Few other models can explain their observed behavior as well.

Technocracy + bureaucracy = sloth. There's no incentive to risk anything. You aren't directly answerable to the people whom you consider beneath you anyway. Nothing improves. If FAA won't do their job, then that power (such a

Yeah it's really disappointing that even in high cost consumer electronics there's very little incentive to innovate in non-sexy areas :(

Well the big electrolytic caps you need for the passive filters are infamously unreliable which is why you see everyone trumpeting their "Japanese" brand capacitors which are supposed to be better. The caps you need for the active

Could be denser. Instead of a big passive EMI filter, use an active one (noise cancelling, essentially). It's a little baffling why they aren't more widely used, they aren't that complicated. https://u.dianyuan.com

You can make a very limited clone using the st25r3916 mikrobus click board and a sparkfun rp2040 carrier Not the same but actually available to buy. Same NFC chip, no ui, no sub ghz sdr chip.

It's pretty common to license peripheral bits of an ASIC from other companies. You don't even get to look at their blobs or much else.

Oh my god this is incredible! And it has the full pinout so you can use debug accessory mode! Game changing!

You don't get promotions from speeding up code, unfortunately. Nobody cares about something that's difficult to motivate to the program managers or demo. Clearly some egos have been bruised, but that's the reality of open sou

The "Use logging's interpolation" warning has always annoyed me. If logging is in your hot path, that might be an issue. Me f-string interpolating some info logs that run once for convenience is not. Low value junk like this

From the Boehm article: > Many users consider the result of 1+2 to be a finite number, and find it confusing to be able to scroll through lots of zeros on the right.
