The Man Who Sold Hot Dogs

Note: This timeless story pre-dates the web, and it has appeared at WisdomGroup.com. Author unknown.

There was a man who lived by the side of the road and sold hot dogs. He was hard of hearing, so he had no radio. He had trouble with his eyes, so he read no newspaper. But he sold good hot dogs. He put signs up on the highway telling how good they were. He stood on the side of the road and cried “Buy a hot dog, mister?” And people bought. He increased his meat and bun orders. He bought a bigger stove to take care of his trade.

One day, his son came home from college to help him out.

Ack 2.0: Written in Perl, Useful With Ruby

Ack is an open source command line tool that lets developers search large trees of source code very quickly. If you are looking for a method definition in a haystack of files, Ack will find that needle for you. Many devs regard Ack as a replacement for grep.

The Elmhurst ChicagoRuby meetings are always a source of unexpected learning. Today ChicagoRuby welcomed Andy Lester, creator of Ack. Andy released Ack 2.0 two days ago. He shared some of the latest features in an impromptu demo.

New RVM Behavior With .ruby-version and .ruby-gemset

I trust RVM to manage my Ruby versions and my gemsets. So when I saw an unexpected change in RVM’s behavior, I was concerned about a possible disruption in my workflow.

Elegant Code

This quote is too long to tweet, but too good to pass up:

Ugly programs are like ugly suspension bridges: they’re much more liable to collapse than pretty ones, because the way humans (especially engineer-humans) perceive beauty is intimately related to our ability to process and understand complexity. A language that makes it hard to write elegant code makes it hard to write good code.
