- Comment on The way two of the usb's are one way while the other is another way 16 hours ago:
I kidt had a problem with my boss’s conouter yesterday where Windows decided it didn’t need to load the drivers for one of the two built in USB 3.0 controllers. On boot, only one of the two controllers would work, either the one for the front ports, or the one for the rear ports.
BIOS recognized a keyboard or mouse in any of the 2.0 or 3.0 ports at POST, but if Windows failed to load the 3.0 driver at boot time, it dropped the keyboard and mouse.
Workaround was to swap them to the 2.0 ports. Final solution was upgrading to Linux.

Suppose he willed his car to his living son, his house to his son, and the remainder of his estate to Bob.
He dies. Son is alive. In this case, son gets house and car. Bob gets everything else.
Suppose son dies first. In this case, the house transfers to the son’s estate, where it is then transferred to son’s heirs. The house was bequeathed to the “son”.
But the car does not transfer to the son’s estate. The car was bequeathed to the “living son”. The car transfers to Bob with the rest of Dad’s estate, not to the son’s heirs.

$5000-$15,000. If you can’t afford a vasectomy reversal, you can’t afford kids.

While it’s not guaranteed, chances are very good that it can be reversed. If you change your mind later, you can attempt to reverse it.
Nobody should be having kids before the age of 30 anyway.

- Comment on I explained economics to my nine year old 1 week ago:
It’s less to do with “tiny variables” and more with the fact that the foundation of the “system” is the capricious whims of human fancy.
“Economist” falls in the same category as “alchemist”, “astrologist”, “psychologist”, etc.

- Comment on "Pilot had to dive aggressively to avoid midair collision over Burbank airport." 1 week ago:
Without pilot intervention, the closest they would have come would have been 4.85 nautical miles laterally, and at the same altitude.
With the pilot intervention, the closest they came was 4.85 nautical miles laterally, and 500 feet vertically.
- Comment on "Pilot had to dive aggressively to avoid midair collision over Burbank airport." 1 week ago:
Agreed. The point of a conservative warning is to give plenty of time and opportunity to react without bouncing your passengers off the ceiling.
Fault for the loss of separation seems to be on the controllers. Not all separation incidents are the same, though. This one seems to be rather minor. By my estimation, the encroachment was a maximum of 264 yards, and the duration of that encroachment (without pilot or controller intervention) would have been less than 10 seconds. Too tight, yes. It needs addressed so it doesn’t become a habitual violation that could lead to more severe encroachment by these controllers. But there was no real danger of bodily harm from this encroachment.
Fault for an overly aggressive maneuver is on the pilot. There was a risk of injury from that overly aggressive response. The pilot’s actions elevated a minor, no-risk event to one that risked serious injury to the passengers and crew. But, he was following instructions from a device designed to improve aviation safety, and the nature of the warnings from that device, an over-response is much safer than an under-response. He has to trust his instruments, and his instruments (erroneously) told him to push the nose down, quickly, lest he hit another plane.
TCAS is designed and intended to reduce risk and prevent harm. In this specific incident, though, it seems like the TCAS-RA actually increased the risk of harm, by calling for an immediate action that wasn’t actually necessary to prevent harm. Is there a way to improve TCAS?
I, too, would like to know how often TCAS incidents were recorded before and after the layoffs. Those layoffs definitely harmed aviation safety. But if someone were injured in this incident, I don’t think I could point the finger at the controllers or lack thereof. This particular incident seems to suggest a shortcoming in the TCAS system.

- Comment on "Pilot had to dive aggressively to avoid midair collision over Burbank airport." 1 week ago:
Just to put this into perspective, here’s a visualization of the flight data. The two aircraft were never on a collision course. They slightly violated a 5-mile separation requirement: their closest point of approach was 4.85 miles. The pilot did need to respond to the TCAS alert, but that alert was very conservative.

I read once that you can use a tampon instead of a rag, but I think that would likely blow out when you throw it. But, you could stuff a corner of the rag into the bottle, and then force a tampon in behind it to secure the rag/wick.

filling it with alcohol/gasoline
You’ll want to experiment, but a 50/50 mixture of gasoline and diesel fuel will give improved results. You can also dissolve Styrofoam packing peanuts and/or soap flakes in the gasoline to give it a stickier consistency.

- Comment on Why don't Americans use electric kettles? 4 weeks ago:
Watts are a unit of power. Regardless of voltage, if your appliance is drawing 3000 watts, it is heating up the same as any other device that draws 3000 watts.
Wires are not sized on the number of watts they can carry. They are sized on the number of amps they carry. If a wire is sized for 10amps, and you are using 12v, you can only get 120 watts through it. Increase the voltage to 120v, and you can get 1200 watts through that same wire. Increase to 240v, and you can get 2400 watts from that wire. The higher the voltage, the less copper you need to carry it. You need thicker insulation to handle that increased voltage, but insulation is cheap. It’s more dangerous to humans who come into contact with the wires, but you can build in additional methods to restrict human contact, such as fancy plugs and sockets.
The UK and Europe had a severe copper shortage when they rebuilt after WWII. They standardized on 240V to reduce the size of wires they needed in their homes. Instead of dozens of, low-amp circuits, they installed only a couple high-amp circuits for their entire home. They designed their household wiring so that the same circuit that powers the alarm clock on their nightstand is also used for their 3000-watt space heater.
They further reduced copper consumption by using undersized wire in a “ring” circuit instead of properly sized wire in a “branch” circuit. Failures in ring circuits are extraordinarily dangerous, because there is no immediate indication that they have failed. Each outlet receives power from two sides of the ring; if one side fails, they draw all their power from the other side, overloading the ring.
The US solution to these problems is intrinsically safer household wiring. We threw copper at the problem, because we had the copper to throw. But what we got in return was a vastly safer system. We managed to get a 240v system that only carries the risks of a 120v system.
- Comment on Why don't Americans use electric kettles? 4 weeks ago:
The issue isn’t the voltage. It is the wattage. UK kettles draw 3kW. US outlets are (typically) only rated for 2.4kW. We can easily get dedicated 30A, 120v outlets that will provide 3.6kW.
US 240v is not the same as UK 240v.
The UK uses a single live phase, (240v with respect to ground), and a neutral (0v with respect to ground).
The US uses two live phases. Each phase is 120v with respect to ground, but they are 180 degrees apart from eachother. Phase to phase is 240V, but either phase to ground is 120v.
A UK kettle expects its neutral phase to be at the same potential as ground, which can’t happen in the US without a 1-to-1 transformer
