As we are coming up on the end of the year I want to take a look at a project which is unique and outside the mainstream of Linux projects. I don't think any project embodies distinct and useful technology quite as well as Puppy Linux does. Puppy's 5.4 "Slacko" edition was released recently and it struck me as an interesting and fun way to wrap up the year.
