I’m not sure why, but the Ruby Corner is always picking up on my next-to-last post. Weird. I wonder if it’s something I’m not doing properly or what……

Break my code, please
There’s a number of things we can should take into account when writing code — boundary cases, etc., that can make or break a programme. Yes, testing is important, but I think that developing good defensive programming practices is even more important. That said; I present the following, fragile, code. Just about every line has …

Ruby’s ObjectSpace: Subclasses

Oooh Shiny! Magpies don’t know what’s just enough!
I’ve done it. I’ve been guilty of ooh shiny development. You know, those projects where you use the latest and greatest library, tool, or infrastructure not because it’s the best thing to do but because it’s the cool thing to do.

.irbc contents
I think that irb is one of the most useful tools in the rails toolbox. It allows me to quickly determine how something works, sample results (for putting into blogs, don’tcha know) and makes me a more effective ruby developer. One of the nice things about irb is it’s .irbrc file where you can place …

Just Enough Programming: The missing cornerstone
I was just speaking with a coworker about JEP. In the course of our conversation I realized that in my list of the foundations of JEP, I had left off what is perhaps the most important one of all — Pragmatism. If I were to sum up and explain JEP in one word it would …
