How To Get Into Programming?

writermike asks: "Like many on Slashdot, I practically grew up with computers. I've had one or more since 1978. However, unlike a lot of people here, I simply never learned how to program. Twenty-seven years later, I still know nothing about 'programming.' I'm a fairly successful technology troubleshooter, having been in that role for 15 years, and I find as I delve deeper into why programs fail, my interest in programming rises, and I feel that not knowing the principles is a hole in my knowledge that hampers me a bit. There are so many books and courses out there that seem to focus less on principles and more on specific languages and/or the 'career-track'. I don't really want to code the next great web service. I want to learn principles, then begin to learn a language. Where can I begin the adventure I should have started back in 1978?"

...just start programing.

I'm reminded of the joke: "How can I make money in the stock market?" "Easy: buy stock at a low price, sell it at a high price." Strictly true, but not very useful. Exactly how do you "just start"?

The answer to that depends on what you hope to learn. Programming is a big topic and there are a lot of ways to approach it.

Probably most Slashdotters will answer this question with something practical and job-oriented. "Get a copy of Kernighan and Ritchie, C is a language everybody should know." "Download Perl." "Download the Java SDK." "Use the VBA engine in Word to write macros." Etc. All worth doing if you're looking for a career as a programmer. But I sense that this guy is motivated more by intellectual curiousity than by career development. (As he should be — the developer job market is a tad oversupplied.) He's used computers most of his life, but has an unsatisified curiousity about how the suckers work.

One good way to satisfy that curiousity would be with the very basics: machine language and assembly language. These are not useful skills for most programmers, who only need to know the high-level abstractions of the systems they work with. (Some people would disagree with me on that.) But for satisfying your curiousity about just what computers do, it's a nice exercise.

Or instead of going very low level, you can go very high level, and learn some basic computer science while you're at it. That the route if you read the classic Structure and Interpretation of Computer Programs and work its Scheme programming exercises.

Then again, learning programming on your own is not for everybody. If somebody has managed to be around computers for a long time, but has never go around to learning programming, he probably is the sort of person who needs some initial handholding. Community colleges often have good classes.
