If you're not American or English isn't your first language, I realize that doesn't really translate. Its short for the euphemism "everything but the kitchen sink," which is to say as much as possible. The idea is that if you take everything with you, you're prepared for anything. This is sort of like the phrase "when pigs fly": an example in Spanish that means basically the same thing would be "cuando la rana crece el pelo" which means "when frogs have hair"; it doesn't make any sense to people not familiar with the saying but is equivalent.
The idea for Kitchen Sink is that I put as much in this archive as possible. Other portable collections only put in open source software (PortableApps.com), only very small tools (Tiny USB Office), or only tools that will tie into their internal system (Lupo). I put in EVERYTHING I can but avoid:
- Duplicate programs
- Anything buggy or overly obscure
