As someone who makes a living writing software, I experience the nature of my work and the opinions of the communities of programmers I encounter as generally consistent: programming is hard; tools help a bit; but there are no silver bullets, only lead ones. But there are remarkable discontinuities in this experience. From time to […]
I keep a text file open as I work, and when I learn something, or fix a bug, I make a note of that in the text file. I call it my journal. It’s pretty low-tech, but text search turns out to be a sufficient way to look up past experiences when I find myself […]
At RailsConf, Jeremy McAnally noted that no one had built a new-style Rails generator for the mustache template system. So I’m giving it a try. You can see my progress so far on github. I’ve forked the rails3-generator project started by José Valim and carried on by several contributors, and I’ve added just a little […]
A few weeks ago I posted about my initial impressions of CommonJS’s approach to concurrency, in particular the use of promises. Today I add my look at promises and futures in Clojure. I’m aware that I’m kind of writing these blog posts backwards. I’m learning more as I go, which means before I’m done I […]
The haters are wrong, part one I just finished an excellent blog post by my friend Blake Patterson. It’s about the iPad. Blake realized in the wee hours of Sunday morning that the iPad was actually Alan Kay’s Dynabook, emerging after 40 years in Steve Jobs’ turtleneck-clad arms. Seriously, it’s a great post. Go read […]
It’s a concurrent world, and, increasingly, it’s an asynchronous world too. Many things are going on at the same time, and it’s impossible to determine exactly when each is starting or ending. In other words, everything is fast and out of control. As a software developer, both concurrency and asynchronicity are more important concepts than […]
I’ve wanted to cite this passage a few times now, but I can only find the essay in PDF form. So I’m just going to put the passage here, so I can point back to it in the future. Geeks, if people regularly joke that they couldn’t understand what you do for a living, consider […]
I gave a talk on Ruby’s Enumerators at the DC Ruby Users Group in August. I’ve posted my slides from the presentation, if you’re interested. Basically, I discovered that enumerators make lazy evaluation easy to implement in Ruby, and applying lazy techniques with enumerators may yield more efficient and elegant code.
