I couldn't have a blog and not post something about the Hamster especially as its the name of the blog.
Since 1999, when I joined Vignette, I've used the term Hamster. No particular reason. Sometimes used as a greeting, it's said "Hamstaaaaa!!"
I recently found this little gem on a dictionary site
1. (From Fairchild) A particularly slick little piece of code that does one thing well; a small, self-contained hack. The image is of a hamster happily spinning its exercise wheel.
The people I've used this term with over the years have been highly skilled people I have alot of respect for and this somehow seems even more appropriate now.
