Jeremy Miller at Code Better gives some advice to developers who are trying to sharpen their saw.

It's also good advice for anyone wanting to start a career in software development.

Similiarly to Jeremy, I wonder if other managers feel the same way about concepts/fundamentals and getting involved with open source projects.

Of course blogs aren't credible so everything Jeremy says is BS, right?

I think you're smart enough to decide on your own.

What about his comment that makes the suggestion to move on if you're in a moderate engineering company?

Are you the rockstar at your shop? Would you rather move on than continue to improve and stay the rockstar?

Is it true that you're only as good as your weakest link?
