Whether or not cannabis makes psychosis more likely isn't proven, but your N=1 study illustrates how bad it often is. People should know that psychosis isn't just having some weird ideas, but often destroys lives and families.

A naive estimate of accuracy is that, at a rotation speed of 5/sec (1800 degrees/sec) a 1 ms error in release time causes a 1.8 degrees aim error, or 3 yards at 100 yards. You could hit the broad side of a barn, but not a buffalo.

Once you dig up the top kilometer of a planet's crust, what's under your feet? The next kilometer! That would suck to do to Earth, but we can launch all of Mars's mass into the swarm.

The burned propellant and oxygen mass (as H2O and CO2) almost all ends up back in the atmosphere when you launch to LEO, so you can keep running electrolysis (powered by solar) to convert it back to fuel.

The energy to build the system comes from the partial assembled system, plus some initial bootstrap energy. It grows exponentially. We seem to have enough today to build small factories in orbit. The manufacturing scale comes from designing

People can build a factory that makes satellites. And then a factory that makes factories to make satellites. There is plenty of material in the solar system (see my other response), and plenty of orbits, and launch capability can scale wit

The inner planets contain enough mass to create a shell of 1 AU radius with mass of 42 kg/m^2. That sounds like a plausible thickness and density for a sandwich of photovoltaics - GPUs - heat sinks. You don't build a rigid shell o

What do you think the limiting factor is? I don't see why we can't scale manufacturing of satellites up as far as we want. If we mine out a substantial fraction of the mass of the earth, we can go harvest asteroids or something.

If you set Time Machine to use encrypted backups, it will create a fake disk that's really a directory tree with a bunch of gigabyte-sized binary chunks. This is safer because it doesn't require the file system to support anything

https://www.brennancenter.org/our-work/research-reports/poli... has a list of police body cam retention policies. 90 days is pretty common, though it ranges from 30 days to 5 years. Documents are kept longer. But

Deleting data according to a pre-defined schedule (often 90 days) is legitimate and standard. It's good that agencies do this, to limit exposure due to data breaches. And it's normal for courts to issue a preservation order for sp

I think the PG designers would be surprised by the claim that it wasn't designed for this. Database designers try very hard to support the widest possible range of uses. If all queue actions are failing instantly, you probably want a s

All of which is arguably true, but misses the point that uploading your age verification documents to every social media site you might want to look at is very likely to result in them getting hacked and leaked. Working with startups, I&#x2

Right, if there's something like a small hole in a pressure tank, it's very unlikely to be aligned exactly with the CG, so the tank will spin around and the net thrust will be near zero. If a pressure tank splits in half, both hal

At the speeds we're familiar with, basketballs and golf balls have elastic collisions. At orbital speeds, satellites are nearly inelastic. So fragment exit velocities lie between the two initial velocities, k v1 + (1-k) v2 for some k t

You could launch some missiles, blow a few satellites into smithereens, and gradually over the next few months they would take out the others. That's a poor kind of war weapon. An effective weapon is one where you can inflict damage co

If you're copying from another painting, you don't paint a figure and then decide to move it a centimeter to the left. But original paintings often have such changes.

No one will ever agree on when AI systems have equivalent functionality to a human brain. But lots of jobs consist of things a computer can now do for less than 100W. Also, while a body itself uses only 100W, a normal urban lifestyle uses a

The opposite. The (unsubstantiated and probably false) claim is that the Green party was helped or funded by Russian energy companies, who benefited by Germany shutting down its nuclear plants.

Checking the arithmetic in every paper published seems like an good use case for LLMs. Has someone built a better version than uploading a PDF to ChatGPT and asking it to check the arithmetic?

It's rare for there to be little wind in the North Sea. It's only a couple days a month when it's below 1/3 capacity. And it's negatively correlated with solar: a day that's both cloudy and low-wind is very rar

Sailors had a lot of harmful sayings. It's possible to navigate without being able to measure your longitude. Like if you're looking for an island, you should first navigate to the correct latitude and then sail along that latitud

My conclusion is that microkernels offer some protection from random reboots, but not much against hacking Say the USB system runs in its own isolated process. Great, but if someone pwns the USB process they can change disk contents, interc

Given that inside information makes prediction markets more accurate, why do you believe it doesn't make stock markets more accurate? If, say, Enron insiders could've shorted their own stock, that would have improved accuracy and

Nations have a tipping point where the violent minority can take power if there are enough of them. "Enough" might be only 10%. So a nation with 10% violent people is violent, while a nation with 9% violent people is peaceful. It

It works somewhat better at the national level than the company level. By encouraging companies to move fast, some will fail but the employees will have gained experience that gets carried into other companies in the industry. At the compan

The people who show up to town council meetings lean heavily to the side of security over liberty. The most obvious reason is that it's mostly retired homeowners with busybody personality types. Privacy and liberty advocates are unlike
