how ignorant are you?

[BigV]

I understand much in the way of mechanical devices. However...

Steering and suspension and alignment are all out of my league. I don't even know how they do it in the shops.

There are considerable gaps in my understanding of how radio works. I have even built an extremely simple crystal radio, and I still don't understand how the little machine can pull the music out of the air and pipe it into my head.

There are a ton of things I don't understand the why of even if I understand the how of. Fancy wrapping paper, headed straight to the trashcan. :scratches head:

The Wankel Rotary Engine? I've owned them, and seen all the cutaway drawings, and I still don't completely follow it. Only three moving parts. Elegant, supremely elegant.

more later...

I'm a fair programmer, I still don't understand:
Continuations
Closures
or why people think Best Practices are a good idea.

Reading Programming Ruby: The Pragmatic Programmers' Guide will give you a good start on continuations and closures. The Ruby language has both.

Best Practices, at least the way we use them, are just rules of thumb. They are a formalized equivalent of "Hey, you know what works for me?".
