How Transistors REALLY Work

How Do Transistors Work?

Electric current never flows, since an electric current is not a stuff. Electric current is a flow of something else. (Ask yourself this: what’s the stuff that flows in a river, is it “current” or is it called “water?”)
Wires are not full of current, they are full of charges that can move. Electric charge is real stuff; it can move around. But electric current is not stuff. If we decide to ignore “current,” and then examine the behavior of moving charges in great detail, we can burn off the clouds of fog that block our understanding of electronics.

An excellent explanation of electronics and transistors.

Someone’s List Of Essential Algorithms

5 algorithms you must know:

Algorithms are underrated and probably underused – it comes up maybe 1% of the time, but in that 1% of the time, it’s 100% important. These are real algorithms, with real-world application, but the lesson is in the paradigm.

They list Sorting, Binary Searching, Hashing, Dynamic Programming, and Search Algorithm.

The first four are common, although most people I know simply google solutions, not knowing they’re using a Quick Sort. I don’t think I’ve used any Search Algorithms in my professional life.

Knuth‘s Fundamental Algorithms (volume 1 of his The Art Of Computer Programming – you DO have a copy, don’t you?) describes how to use Linear Lists, Trees, and similar structures. He devotes all of Volume 3 to Searching and Sorting.

LOTS of links. I tend to forget about sites like this, relying on google instead.

I think Pender sent me that link long ago.
