This is a pretty late response, but even as "not too north" as Hamburg it gets close to 10%. Hamburg is at 53.6 degrees North; Berlin is 52.5. Both are just farther north than Calgary, as a pretty reasonable comparison for the US.

Analyzing the industry is tricky, though - do you sell to a feedlot, or raise on pasture to slaughter? (Most cow/calf operations sell to a feedlot, but you sound like you may be keeping them all the way?) The drawback to fully pasture-

Over provision the panels by a good margin and have them at a more southerly angle (for northern hemisphere). You can play around on nrel pvwatts to see what configuration produces the most even expected monthly output: https://p

It's not clear from just pasting a link what you're trying to say in this context. Could you elaborate? PFAs and fluropolymers are all fluorine based. Most plastics and geopolymers are not.

No. Polymers are a general class of molecules that consist of a long chain of repeated subunits. Plastics are polymers, for example. (Poly - many) PFAs specifically have chains of carbon-flourine bonds, among other differentiators. For geop

The 48 bytes of sram are enough to encode several state machines. It has pwm and dedicated IR signalling output, but no ADC for input. It's generally designed to be a very simple controller-of-things. Push an up button, increase the pw

There's a saying from Rod Brooks that I quite like: "Simulations are doomed to succeed." The hard part is making sure the simulation captures enough of the relevant factors and that the physics/etc simulation is accurate

I didn't downvote you, but it seems like a pretty nitpicky question to ask at the "we demonstrated that the thing worked and didn't melt" stage. It shouldn't have to compete - yet. Your question doesn't get at

Don't do that. (Deliberately misgender someone).

Of course not. How would they be able to get over mountains? Or through the English Channel?

It's not a stupid question. And yes. It'd be fairly localized, but the absorption losses would be somewhat proportional to the amount of water in the air, so, uh, don't do this on a rainy day. But the climate effects are prob

Yes, you have to analyze the embodied energy, but solar panels are energy positive within 1-2 years these days: https://www.quora.com/How-much-more-energy-do-solar-panels-p... It's really a no-brainer up to a certain a

Oh, wow - thank you! Looking at the evolution of the Jumars in that is fascinating -- you can see them go from really clunky prototypes to looking like a modern ascender.

I don't know how common this is in row crops, but it's exceptionally common in cattle ranching. The majority of cattle producers ("cow-calf" operations, the ones who raise cattle from birth to about half-grown) are small

The difference between a mid-drive (in which all of the force goes through the rear cassette) and a rear hub drive (in which only the pedal force goes through the rear cassette) is large. Also, most people online report over 2k miles on a c

I think the follow-on post above about making sure to be better about maintaining the chain is part of it. I'm a little lazy with my road bike chain because I mostly only ride it in good weather, and I carried the same attitude to the

The gear advantage of a mid-drive rocks but I was quite surprised that I chewed through a rear cassette in under a year / about 1k miles -- a 250W motor + heavy cargo bike + kid passenger + a large and pretty strong rider exert an awfu

Some quick checking: Average (well, median) US house size: 2000 ft^2 Average UK house size: 68 m^2 = 740 ft^2 That makes for a very, very different HVAC bill. Numbers vary a lot by source but the relationship (2x+ larger in the US) holds. F

Imagine the equivalent of endoscopy: being able to insert a small tube inside of an object and print structures larger than the tube inside of them. Obviously, that requires a lot more than just this, but it's intriguing to think about

Though it's a continuing puzzle to me why ESPs have worse ADCs than the rp2040, given their relative maturity. (Neither is particularly good, mind you, but I'm generally ok with the rp for my toy applications.)

1) (new and innovative) and (safer, written in rust) are orthogonal attributes. (2) Rewriting isn't necessarily a waste of time. There are rewrites of some wretchedly vulnerability-prone (and poorly extensible) core infra like ntpd, su

Oh, no disagreement. "Practical" really means "practical for math things where you want to guarantee correctness, not just have extremely high confidence". I can't think of any normal use of primes that needs someth

Because for practical things we have a faster solution that might also be wrong occasionally (randomized testing). There's no benefit to using any of the known deterministic tests if they're not truly deterministic. The speed gap

by dgacmu 2y ago
If we knew that the extended Riemann hypothesis was true, we could use the Miller test for deterministic primality testing in log(n)^4; the AKS test, which doesn't depend on RH, is lg(n)^6. Do we care? Not for most applications -- doin
