Loosely integrated development environment 4 weeks ago

Small pieces loosely joined. It was the title of a book written by David Weinberger back in 2002, but one could say it’s also become something of a mantra for software development for the 21st century. Good software is not monolithic; rather it is composed of small pieces, easily testable, …

Reverse-engineering the "breathing" LED 6 months ago

Perhaps it's not surprising, but Apple has a patent on the iconic "breathing" pattern used for the sleep indicator LED on all their computers. Recently — for a personal project — I wanted to see if I could replicate this effect. It turns out that I wasn't alone. Ladyada had also …

Sifteo development with MVC and Ninject 6 months ago

This is a follow-up to previous tutorial on getting started with the Sifteo SDK. If you haven't at least managed to get the example applications from the SDK running, I suggest you start there first. Introduction Once you have the Sifteo SDK installed and working on your system, and you're ready …

Up and running with the Sifteo SDK 7 months ago

I’m pretty excited about Sifteo cubes. I’m even more excited about developing for them. If you’re unfamiliar with Sifteo I recommend checking out the 2009 TED Talk where early prototypes of Sifteo cubes were first introduced to the mainstream. Sifteo cubes represent an entirely …

Why Haskell? 8 months ago

I’m learning Haskell . Maybe you should too. Here’s why: Every programmer has something to say on what other programmers should know in order to be standouts in their field. Back in 2004, for instance, when Python was more obscure than it is now, Paul Graham wrote an essay about …

Thoughts on test-driven development 8 months ago

Clean code is all the rage these days. It’s what all the cool kids are doing. Which is a bit odd, because you would think that clean code should never have been a fad, but rather a staple of software development since the earliest days of FORTRAN. Such is not the case. Instead, it took the …

God, causation, correlation 8 months ago

It’s amazing how frequently studies and statistics are misconstrued for the purposes of demonstrating causality when they actually show no such thing. Sloppy journalism is usually the culprit. For instance, the first sentence of recent article in The Times, entitled Societies worse off when they …

Against being against 8 months ago

The Dalai Lama isn’t as famous as I thought, but he sure can draw a crowd. Yesterday, for instance, I saw him speak at a packed stadium in Tucson, Arizona that felt far more like a giant, over-air-conditioned meat locker than a speaking venue. Nevertheless, His Holiness (or H.H. if you’re into …

A Zen fart 8 months ago

I love this little parable, and felt inclined to re-post it here: There was once a zen monk whose master instructed him to go out into the world with nothing but his robe and begging bowl until he had dissolved his ego to the point where he was no longer blown and buffeted by the winds of praise …

Self wonder 8 months ago

Though I may not see it with the same Augustinian eye, I still love it nonetheless: People travel to wonder at the height of the mountains, at the huge waves of the sea, at the long course of rivers, at the vast compass of the ocean, at the circular motion of the stars; and they pass by …
