Show Navigation

In the end, much of the challenge of programming is in identifying and holding tight to every invariant you can find, those things in your algorithms, applications, or business rules that do not change. The more invariants you can identify, the more you can focus on the local effects of a particular piece of code, and the more risk you can drive out of whatever system you are building.

I’m now convinced that choosing a language based on how easy it is to read or write is a very bad idea. What if we chose musical instruments based on how easy they are to play? Everyone would playing kazoos. You can’t think deeply about music if all you know is a kazoo. Skill at reading and writing code is learned. We should choose languages based on how accurately they allow us to think about the problems we are trying to solve.
