This article looks at a couple of approaches for implementing systems with recurring events using message-passing based concurrency (Erlang and Clojure are used in code snippets). In particular it looks at the ping-pong, circle, coordinator and gossip approaches to distributed communication.
I use Markdown for most of my online writing, and also as the format for most of my personal notes. Since I also use Graphviz quite frequently, adding an extension to handle both seemed like a reasonable next step.
We don't know how long we'll live, but we do know our time is limited, and life could be thought of as our endeavor to optimize the economics of our time. Yet, much like the current financial debacle, often the attempt to optimize ends poorly.
The aim of a development group is to build business value. Building technical leverage is the focus on increasing the business value a development group delivers over time.
A reflection on a day when I accidentally broke a production environment by trying to fix a failed deployment. Definitely one of my learning experiences from the past year.
With ten minutes before bed and 35 megs of images to scale, I had my first encounter with Automator. It was a good encounter, and I heartily recommend it to others for--at minimum--batch scaling images.
I wanted to do a fairly mindless little scripting project after spending too much time on well documented and maintained code. It's important to let your hair down sometimes. In this project I use Python and the Python Imaging Library to create a simple photo album.
Answers to a bunch of questions about JET that I get asked frequently. If there are any questions that I didn't answer throw me an email and I'll do my best to answer them.
Once again we're experimenting with a paper reading group for our engineering team, this time with more success than previously, albeit in an unintended direction.
