Paul Ford: What is Code?

This issue comprises a single story devoted to ­demystifying code and the culture of the people who make it. There’s some technical language along with a few pretty basic mathematical concepts. There are also lots of solid jokes and lasting insights. It may take a few hours to read, but that’s a small price to pay for adding decades to your career.

Seriously, do yourself a favour and read this. A really exceptional piece on computing, computers and the curmudgeonly subset of people known as programmers.
