Many hard engineering fields see the impact of their work on the environment directly. Using sustainable materials in your products implies that they’re better for the environment than they might otherwise be. How does this translate to software engineering? Certainly, there are the direct contributors. The maintainers of the linux ACPI kernel module that allow [...]
A fellow engineer asked me about parsing XML in Java and I handed them this utility class I wrote a while ago. The class fit her need so well, she suggested I post it for others to use. It’s only a few lines of code, but it is useful. I find the nodeListTree2Hash method to [...]

I’m building a system that maps a user’s IP to a physical location. This kind of stuff has been around for a while, and it’s so easy I don’t understand is why it’s used so infrequently. It’s as though it’s seen as a tool for the mega-corp ad networks like Yahoo and Google/DoubleClick, but there [...]
About 6 months ago I wanted to pull some data from a bluetooth adapter into a little java app. I did the usual google searching and found (among others) jBluez. Being free and working on Linux, this seemed like the right solution for me. But there are problems with jBluez. It has a few bugs [...]
