Engineers describe a system whose input and output behavior are known and whose inner workings are otherwise mysterious as a black box. Bruno Latour describes the black box as: the way scientific and technical work is made invisible by its own success. When a machine runs efficiently, when a matter of fact is settled, one …

How transistors think
The parts of the computer that do the “thinking” are mostly made of little electronic switches called transistors. If you connect two wires to a transistor, you can use the voltage on one wire to control the voltage on the other. What’s especially handy for engineering purposes is that the presence or absence of a …
Is technological progress good or bad? Yes.
Technology keeps getting better. Do our lives get better as a result? In certain specific ways, maybe yes, but in general, I would say, not really. How is that possible?

No one has ever written an original song
Sampling, remixing and mashups make some people angry. A lot of people think that repurposing existing ideas is bad, that it’s lazy, or a form of stealing. We value originality highly. Should we? My own experience of music making is that there are no original ideas. There are novel combinations of old ideas, but it’s …

Robot counting for humans
When you delve behind the scenes with the internet, you immediately come face-to-face with a lot of threatening computer gibberish. The most menacing codes are the ones that stand for colors, random-seeming strings of letters and numbers like #99CC66 or #4F102A. Sometimes you see colors described verbally: “black”, “white”, “blue”, etc. That’s fine for simple …

Why I love Gawker
I’m a jazz guy. I like improvising in front of an audience. I like publishing a post while it’s still only a third finished. It keeps the fire lit under me to get the rest written. I was looking for a blog platform congenial to this method of working. Then I read a PC Magazine …

Turning sound into electricity At the physical level, a sound is a rhythmic vibration of air molecules. Your ears can detect subtle …
