A search for programming knowledge and _why

posted by Jason Kottke   Mar 15, 2012

For her yearly month-long project at Slate, Annie Lowrey wanted to learn how to code. She picked Ruby and became interested in the story of _why, the mysterious Ruby hacker who disappeared suddenly in 2009. In a long article at Slate, Lowrey shares her experience learning to program and, oh, by the way, tracks down _why. Sort of.

The pickaxe book first shows you how to install Ruby on your computer. (That leads to a strange ontological question: Is a programming language a program? Basically, yes. You can download it from the Internet so that your computer will know how to speak it.)

Then the pickaxe book moves on to stuff like this: “Ruby is a genuine object-oriented language. Everything you manipulate is an object, and the results of those manipulations are themselves objects. However, many languages make the same claim, and their users often have a different interpretation of what object-oriented means and a different terminology for the concepts they employ.”

Programming manual, or Derrida? As I pressed on, it got little better. Nearly every page required aggressive Googling, followed by dull confusion. The vocabulary alone proved huge and complex. Strings! Arrays! Objects! Variables! Interactive shells! I kind of got it, I would promise myself. But the next morning, I had retained nothing. Ruby remained little more than Greek to me.

Scripting language comparisons

posted by Jason Kottke   Aug 17, 2011

An extensive side-by-side reference sheet of four scripting languages (PHP, Python, Perl, and Ruby) with which you can compare how the different languages handle variable declarations, concatenations, objects, and hundreds of other things. Great cheatsheet for learning a new language when you’re already familar with one of the others.
