Don't tell me, the toothbrush was made of metal, right?

Gravity is not a force, it's a warping of spacetime (mostly a warping of time). It's actually a correlation of those (as explained by general relativity), but it's uncertain which causes which, or if there is another variable that causes each of those.

Here are a couple of videos that do a decent job of explaining how the warping of time makes space "flow" into a massive object.

How does gravity warp the flow of time?

Does time cause gravity?

I wrote that quote from memory...

The exact quote was, "Well HAL, I'll be damned if I can find anything wrong with it."

Also, that pic I found was not from that scene when Bowman said that line, it's from the scene when HAL was doing the crew psych evaluations.

That makes sense for that safety reason, but my understanding is that it works like a transformer, except the primary and secondary are in separeate units. And a transformer is inefficient.

There is also a way to transmit power via RF, usually microwaves, but I think that's inefficient, too.

I heard that the US Congress just changed the laws so that if someone who is doing security research ("white hat") penetrates a system’s security, then they won’t get charged for a crime.

Most of the bad guys who attempt to attack my systems, flag their packets as “white hat”, so I don’t know how that new law is going to work. I think they need some kind of way to register white hats and also have a way for admins to give permission, like with robot.txt.

I think wireless charging is inefficient, isn't it? Does your tooth brush or charger get warm when it charges?

It's interesting that the word "accident" can't be use as a verb. You say "I was is in an accident", but you don't say, "I accidented."

On the Pursuit

An artichokes , it’s hard to reach
Peeling the layers, each one a treat
The bristly bristles defending
Easily scooped while upending
Finally satisfaction and joy
Eat your heart out bok choy.

That's why I said, "the leaders of the Confederacy", like Jefferson Davis and General Lee. I don't mind people who want to worship peaches and mint juleps.

The way some people celebrate royalty in Europe reminds me of how some people in the US celebrate the leaders of the Confederacy from the US Civil War. (The Confederacy was the side that wanted to keep slavery.)

======== SPOILERS =========

I said that the cipher that I used was a common one used in real life. Let me also reveal that it has been used for quite some time now. A cryptanalyst may be able to solve this example by using a brute-force attack on the key with special tools, but that would take some time and I wouldn’t consider that “simple”.

Is the password something that can be easily guessed?

This is how most common breaches occur. Cryptanalysis on ciphertext itself doesn’t happen much except in theory or in well-funded efforts such as governments, or when there is a known weakness or backdoor is in play. (Note: Before I said that knowing that the hash algorithm was sha256 might not be useful, but if you're cracking the password, you'll need to know that.)

How long is the ciphertext?

This can give another clue as to the exact encryption algorithm used. (Remember to subtract out the salt header to determine the actual length.)
