This article is a quick introduction to Clojure from someone still learning the language. I work through a few Project Euler problems, refining solutions along the way. In the end I give some general impressions of the language, the install and setup process, and support for Clojure within different development tools. Long time readers of this blog will remember I also used Project Euler to learn Scala basics a while ago. Read the rest of this entry »

I’ve been in need of new workstation for a while, and finally plunked down the cash for it.  I built  a mid range workstation and installed the latest long term release of Ubuntu (Hardy Heron) 64 bit.  The install was remarkably painless, and all of the hardware was auto-magically detected and works great in Ubuntu.  Hardware support is much improved in the recent Ubuntu releases, but if you are looking for a rock solid build that just works with Ubuntu, give these specs a try.

Intimate knowledge of your code editor is required to be competent and productive developer.  Here is a list of shortcuts anyone on the path to becoming an emacs guru should be familiar with.  This shortcut reference card covers mostly intermediate and advanced shortcuts for GNU emacs (most of them will work with Xemacs as well.)  I learned some great new shortcuts while making this cheat sheet; I hope they will be helpful to my readers as well.

This is a list of the best sites on the net for practicing your coding chops, showing off your programming skills, and competing for fame and fortune. Exercise your brain by untangling obfuscation, applying algorithms knowledge, growing your inner math geek, or playing a bit of code golf. These sites have exercises to build on and refine what you already know, or learn the language du jour. Read the rest of this entry »

With all of the gloom and doom forecasts about the global recession and layoffs everywhere, I’m interested to hear how this mess is affecting programmers. Despite the generally abysmal outlook, many statistics specific to the tech sector fall into the unchanged or optimistic buckets.  Meanwhile, TechCrunch and others are proclaiming that the tech industry has been particularly hard hit.  So what say you?
