Simplicity
Someone has taken (I guess) principles of simplicity from the book Simplicity by Edward de Bono, and made a small web site out of them.
I like it. All points are very valid according to my experience as a programmer. Simplicity is one of those things that everybody claim to honor if you ask them, but in reality complexity is king. The “If it works, don’t fix it” mindset, which would be OK if you could create simplicity the first time around.
The principles “Concepts” and “Divisibility” are in a subtle way each other’s counterparts. You break down big things into parts to get them manageable and understandable, and you create concepts for a bunch of small parts, that is, create something bigger out of them, with the same goal — to make them manageable and understandable.
Someone ought to print these on a T-shirt.
