I often hear beginners ask, "Is it okay if I use Google a lot?" while they nervously throw glances around the room.
The answer couldn't be a more emphatic yes.
Google is an essential part of every software developers' job. The kind of people that need to do a lot of thinking on the job are called knowledge workers, and it's been suggested that knowledge workers spend 40% of their time looking for information. In other words, almost half of your job as a software developer is about being skilled with Google.
Granted, I could probably remember some of those if I tried really hard, but it's much easier to look them up.
