I think some folks - when they hear "T-shaped developer" - think "front-end" and "back-end".

What does it *really* mean?

Find a copy of this book (there are various editions online - go for a newer one) and look at the chapter headings.

*That* is a T-shaped developer.

It's the classic problem, though. Most software developers have been too busy developing software to learn software development.

@sleepyfox @jasongorman What? I may have been living under a rock, but this is the first time I see a publisher renting out books. For a ridiculous fee, too. What the f?
@confuseacat @sleepyfox There are older editions available as PDFs around and about the Interwebs.
@jasongorman @sleepyfox sure, yes. But let me freak out about the state of the world for a bit, please.
Is McGraw Hill in the student extortion business or have they simply lost their mind?
@jasongorman this book covers the breadth component. Will also need a deep knowledge of one domain (finance or telecom for example).
