As time drained away, he gawped at the screen like a medieval serf trying to comprehend helicopter controls, confounded by one simple question after another - questions such as where he was going, and how many of him there were. I ground my teeth to chalkdust as his hand hovered over the touch screen, afraid to choose, like a man deciding whether to stroke a sleeping wolf.

Finally the prick was done, and once I had waited for him to collect his tickets and his bloody receipt, it was my turn. Having no change, I opted to pay by card. But just as my hand moved toward the keypad to enter my pin, a voice in my head whispered: “You don’t know what it is.” And it was right.

The previously mentioned teach-myself-to-program-Cocoa-apps app is now available in a more-or-less feature-complete beta version.

The program is called Checkpoint, and is used to calculate scores for a certain style of time-speed-distance road rally. It’s something I had first tried to put together as a pure JavaScript+HTML app à la TiddlyWiki (but without the ability to save), and then as a (buggy) Ruby on Rails app I ran on my laptop. Then I realized that it’s probably one of the few apps that really makes sense to run as a pure desktop application.

Anyway, on the off chance that you think you might find this sort of thing useful, follow the link above. It’s free as in beer and runs on Mac OS X 10.4 and later.
