ahazred8ta··on California's new bill requires DOJ-approved 3D printers that report themselves
In 1700s terminology, the process of regulating (training) the militia has to take place after first gathering the 'irregular' militia, whose members bring their own weapons. This was established even in colonial times. https://en.wikipedia.org/wiki/Regulator_Movement_in_North_Ca... You'll recall the Baker Street Irregulars, and Paul Revere's "You know the rest, in the books you have read, how the British Regulars fired and fled." The 2A's 'Arms' also covers non-gunpowder weapons. The right of the People to keep arms comes prior to issues related to their use.
ahazred8ta··on Why Europe doesn't have a Tesla
For the first eight months of Tesla's existence it was an empty paper shell with no money, no employees, and no office. Musk funded them, led the board, and laid out the strategic plan.
ahazred8ta··on NASA Video Simulation of entering a black hole [video]
A typical stellar-mass black hole of 3.3 solar masses has a radius of 10 km, 10,000 meters. At 100 meters outside the event horizon there is a 10:1 time dilation. At 1 meter outside there is a 100:1 time dilation. At 1 cm outside there is a 1000:1 time dilation.

But because you're traveling at almost the speed of light while you're falling in, it only takes you a few microseconds to fall past these points and get to the event horizon. If there was a mirror 1 mm outside the event horizon, a photon could start from 1000 km away, fall in, hit the mirror, and climb back out in 1/100th of a second, even allowing for time dilation. The spaceship will only spend a very tiny fraction of a second in the high time dilation area, even as seen from outside.

ahazred8ta··on NASA Video Simulation of entering a black hole [video]
That's an urban legend. In real life physics, the traveler is being pulled forward by the black hole's gravity, faster and faster, and as it covers the last few miles it's traveling very close to light speed and crosses the last few miles in a tiny fraction of a second. The time dilation is not enough to cancel the increased speed. There's no wall of molasses. An object falling in goes faster, not slower. Objects falling into the black hole do not actually hover just short of the event horizon, despite appearances.

ahazred8ta··on It's Time for America to Admit That It Has a Marijuana Problem
US Prohibition was from 1920 to 1933. The Revenue Act of 1913 already put income tax into effect before that. And early 1900s import tariffs added up to more than the alcohol tax. But yes, we collected a lot from whiskey in the 1800s.
