Gas taxes are already an effective road use tax, with infrastructure for collection already in place

Gas taxes are already effectively toll-per-mile, with a bonus incentive to get fuel efficient cars. If we start seeing enough EV adoption to dent gas tax revenues, that's a win.

UWB deals with multipath by having very short pulses. The direct path is always faster, so the "true" pulse is the one which arrives first.

UWB is for locating, not for data here.

This doesn't mean driving is useless. Cars are generally air conditioned, and have a greater capacity to carry luggage than walking. ...so cars should this be _slower_ than cars, given these benefits

Gotcha, so the ideas of "Shut Up and Calculate" QM about wavefunction collapse for ideal systems aren't incomplete.

Okay, so you're a quantum physicist and you can answer my question! My understanding of QM is that a quantum's system's state is suddenly and discontinuously changed by a measurement. My understanding of this article is a bit

I think it's fair to count the number of missions (it's at least consistent across engine types), though I'd probably prefer to also see the number of engine-missions as well. But in defense of counting the number of missions

The Dust Bowl threatening people with starvation hardly seems comparable with high rents. If SF got hit by a natural disaster which destroyed the Tech community (analogous to farming as the main industry of the midwest), you bet people wou

I mean, it's not like it's expensive to manufacture! One person soldering and maybe a single board and usb plug, its probably easy to make money if you can sell them for $30 or so in the volumes of 100's.

I don't see this happening. The propeller physics aren't changing. If you are using the quadrotor architechure, directly lifting your playload with no wings, there's a sound-per-kg number that can't be engineered away.

If you're going to be this pedantic, 50 is greater than 48. They're not wrong.

I think younger engineers' morality towards the military distinguishes between technology for great-power warfare, and technology for bombing weddings in Yemen. Aside from some real outliers, nobody of any age wants to lose a war with

Haddington's arm is 5-axis, which is not enough to put a tool in an arbitrary position and orientation. To put a tool in an arbitrary position (3 DOF) and orientation (3 DOF), a 6-axis arm is needed. If their encoder technology is so

Stated goal is 4 customers per month! Are there 4 perpetually bra-frustrated people with unlimited disposable income in NYC? Hell yes! Apparel is a different world from consumer electronics in terms of pricing.

True, but a quick look at the Space Shuttle launch configuration shows that aerodynamics, while not totally irrelevant, were _not_ the dominant concern.

Electric turbopumps are an answer to the question: "how small can you make a commercially viable orbital rocket?" Atmospheric drag effects rocket performance less and less the larger a rocket gets (square-cube law), so that a rock

But, if the birds derive a significant portion of their yearly calories from eating berries during the harvest, you will still do damage to bird populations. Also, an open berry field keeps birds nearby. If the birds can't eat the be

Defies rationality? It's perfectly rational to prefer a system of measurement that is more meaningful to you.

So I'm quite confused by this article's emphasis on boys outperforming girls more in richer school districts. If you look at the scatter plot, girls outperform boys in English by a much larger margin.

I mean, if we attribute this to the period during the Peloponnesian wars, the kids were definitely not alright. The generation of Athenians after Alcibiades definitely didn't do anything good, and Athens ultimately lost the war.

As a github user, i don't see any way the acquisition could possibly make my user experience better. I don't use any microsoft tools (and I _hate_ all windows after 7), so Microsoft integrating with GitHub has no appeal to me. I t

Well, Github execs could do the responsible thing and cut costs. But that sounds hard, and like it would require effort, so here we go. It's sad.

The delta-v also depends on the mass fraction you can achieve. Removing the tanks might mean a much higher mass fraction, so you have the same delta-v with much lower Isp.

How are they going to get a good seal around the rod at it was being consumed? That sounds like it would limit the thrust the engine can achieve.

One thing i saw was that the rocket can throttle, presumably by changing the rate at which the fuel rod is moved inwards.

Why does GitHub need to be acquired at all? Do the costs of running the servers and hosting the free services not cover the revenue from Enterprise users? I believe that any Enterprise users won't notice even a doubling of the subscrip
