With such a drop required could you harness a tide to produce power. Like maybe allow the tide to fill San Francisco Bay and harness it when it recedes.
Also if you are doing the username/password is incorrect you should also add an artificial delay if it's the username is wrong. Because you can tell which one is wrong my seeing how long it takes the server to respond.
This is basically one of my problems with self driving cars and putting your life in the hands of neural networks. It could theoretically be possible to find vulnerabilities in these systems. Someone could possible create some sort of genetic algorithm to evolve a sign that could cause a car to veer off the road and crash.
Maybe i'm just scare mongering or worrying about nothing.
I just don't really feel comfortable putting my life in the hands of something that no one knows exactly how it works.
You act like this is uncommon for you. Taller people have to pay more for cloths, buy larger cars, and consume more food. You pay more in gas to transport the extra weight. There are probably many more this isn't some weird thing.
I feel like this is something that helped a lot of people learn. The first programming language I started to learn was TI-BASIC on my calculator because I was bored to death. I wouldn't really recommend a BASIC-esqe language as someone's first. I really with we had some easy preinstalled language on Windows machines. Maybe have Python come with it or something, and some way for people to know it's there.
