In AC, diodes work half the time, every 1/60 second. The “good” LEDs will have circuitry to fully rectify the AC into DC, drop the voltage properly, and smooth the peaks and valleys, so they will be continuously lit. So the cheap LED Christmas lights might have a slight flicker, and the good ones are steady. (Or get fancy with chasing colors, etc.)

All of that happens inside each of the “bulb” enclosures, or sometimes in a box at one end, so it technically doesn’t matter which end they are getting electricity from, since the socket at the far end is still just connected in parallel to the plug at the near end. (Otherwise you wouldn’t be able to link them together.)

It’s just a really bad dangerous idea to reverse them.

It would still work. But it is VERY dangerous. 1. The far end of the light string will now have exposed metal prongs that are energized at 120v, which can be fatal. 2. If the other end gets plugged into a socket, there is a 50% chance it will be a different circuit on a different phase, which can create a 240v direct short, across a wire that has no properly sized circuit breaker. 3. Using it to plug a generator into your house during a power outage can kill electrical workers trying to fix the outage if you fail to open your circuit breakers.

If someone can’t make the own cord, what’s the chance they know how vital it is to flip the breaker?

Two things: 1: there’s a high chance you do cross live and neutral, or even live and live on different phases. 2: using it to plug in a generator to power your house can kill electrical workers who are trying to restore a power outage. (If you fail to open your circuit breaker.)

My guess is that’s how high it needs to be for the sewer to flow in the right direction.

Spoilers in Connect are not readable when I click them. (White on white) Unless I first select the post so the background in grey.

You can get Mint on a “Live” USB flash drive, so you can boot it up and see if it handles all your hardware before you install anything.

Canines have five digits on their front paws, just like we do. Their “dew claw” is equivalent to our thumb, so the outside digit is still a pinky digit.

I’d guess it’s easier for the paramedics to jump out when they first arrive on scene. Nothing happening in the back yet, so they can look around and see the situation while rolling in.

Replace NT in this list with ME and you have all the consumer versions. NT versions 3.5 and 4 were the business versions in parallel with 95, 98, and ME.

I’m switching back and forth at will, which is unusual for me with this type of illusion.

But obsolete jobs do become hobbies.

It’s also the only way that is portable. A professor could evaluate each student, but has no way to transmit that kind of evaluation in a way that schools or employers across the country would trust. They didn’t know who the professor is, or what his standards are, or even if he is being bribed to pass somebody. (Which would happen much more if the professors opinion had the weight that the standardized test does. )

When you have a few inches flat at the end, fold it over and tape it. Repeat as needed.

The skin of that cowling doesn’t look thick enough to do more than streamlining. You’re thinking of the containment ring found in jet engines.

Not zero reason. Some people with certain disabilities could benefit from such a device. (Stephen Hawking for instance, was limited to about 10 words per minute with his button interface. A brain interface on a similar patient could be closer to normal conversion speed.)

It’s like looking through frosted glass. If you’re looking at someone, and trying to figure out what they are doing. Frosted glass means you can kinda see their overall posture, and some big movements. That’s like the skull cap. In order to use it you would have to make large changes in your brain patterns so it can be detected. But put clear glass, even a small window, and you can see exactly. Even a small window on the right place will let you read their lips, or watch their hands. That’s like the implant. Even though the implant reads a very small part of the brain, the data it gets is very clean and gives more precise control to the user.

The Fourier transform is a way to convert from a raw waveform into all of its distinct parts, and back again. Computers do this for some types of sound data compression, such as MP3. Your ears do this (in the cochlea) when converting the physical movement of sound waves into electrical signals for your brain.

There will probably be a new app for the new chairs. You’ll have to upgrade the chair to keep using the app support.

GMail has an option to snooze an email until a later date. It disappears from your inbox, (but could still be accessed from the snoozed folder) and then shows up again on the requested date.
