I'm not privy to what Boom is doing, but variable intake geometry easily takes care of this.

The faster you go the higher in the atmosphere you can fly, therefore reducing drag (due to air being more rarefied). So it's not as simple as you're thinking.

"It’s long been known that an average person on a bicycle is a more efficient translator of energy per gram per kilometre than any other machine or animal..." I love bicycles!

Not disagreeing with you, but a lot of this is due to drastically lower traffic deaths, because there's very little traffic in Cuba.

On the flip side, you could say they are common enough that they should be on the home row (accessed by a thumb-activate layer switch, of course).

That's the reason why I have a numpad layer on my 46 key split ortholinear keyboard. Your use case doesn't mean you need a physically separate set of keys for this.

I think you meant thanks to a sane(r) macro system? Both Rust and C++ use monomorphisation for generics, I believe shitty compiler errors are due to C++'s templating.

My understanding is that plants with cooling towers don't have this problem. The question is how expensive the towers are to build. Also, some newer nuclear reactor designs don't have this problem as they would operate at much hig

I wonder what other languages you have experience with. C++ is obviously not one of them.

One drawback of Go (in my opinion) is that it has a runtime. So it's very difficult (impossible) to use it with other languages that also have a runtime. So if you learn Go, you'll never be able to use it to interoperate with e.g.

That's the effect of high gherlin and low leptin. It's a well known fact. When I was in the military on guard duty (very funky sleep schedule, you have 4 hours of duty then 2 hours for "sleep"), I was constantly hungry.

Water electrolysis is around 60-80 percent efficient. Hydrogen fuel cells are around 40-60 percent efficient. Plus you spend additional energy to either compress or cool the hydrogen in order to be able to store it. Electricity storage in a

I've used list comprehensions where they make sense. But it's a non-trivial (although a simple) program, so there are for loops too. So I'm using a mix of chain and permutations from itertools, list comprehensions and for loo

I recently ported some very simple combinatorial code from Python to Rust. I was expecting around 100x speed up. I was surprised when the code ended running only 14 times faster.

Oh I wasn't concerned about their greenhouse effect contribution. NOx can cause asthma and bronchitis and can aggravate pre-existing heart conditions. They also form smog. Did I mention that they are bad for the ozone layer?

Burning any fuel in our atmosphere produces nitrous oxides. Synthetic/carbon neutral fuels won't help with that.

Plate tectonics helps with carbon recycling and regulating the temperature of the planet. Temperature drops, rainfall drops (less evaporation), rock weathering slows down (rock weathering normally removes CO2 from the atmosphere). With plat

The final CO2 concentrations are not the problem. The problem is the speed of change. Last time "the planet was much more hospitable", the temperature climb happened over a much, much longer time period. The present speed of C02 i

I've been using an electric razor for years, too, and I agree that they are much cheaper and more environmentally friendly. The only reason I've had to replace them so far is that it becomes impossible to buy replacement blades an

Lead acid batteries have something like 99% recycling rate. Whereas most electronics ends up in the trash.

There is a problem with hemispherical habitats that is often overlooked. There are two forces at play - air pressure acts up trying to lift the skin of the habitat of the ground. This must be opposed by anchoring the habitat to the ground,

An interesting thing happened to me since I started using an inkjet printer with user refillable ink tanks. I actually like to print! I don't have to deliberate "Do I really need this printed?" I don't mind printing a bu

Another advantage of hydrogen-boron fusion is that all the reaction products are charged. Therefore (theoretically) it would be possible to use *very* efficient magnetohydrodynamic methods of converting the reaction energy to electric energ

Yes. Classical keyboards are inefficient in so many ways. Consider that thumb is responsible for 50% of hand function [1]. And we use it to press only one button - the space bar. While pinky is the weakest finger andd we use it for the grea

You're missing the whole split/ortholinear/reduced key count aspect of these custom keyboards.

I've never had a problem with my Ergodox EZ. Maybe it was a particular run that was problematic? I bought mine in August 2018.

Dactyl/Dactyl Manuform is concave. Even more, its shape is programmatically generated, so you can separate control curvature for each axis, stagger, etc. It is literally infinitely customizable.
