Different people can look at, say, a video tutorial and take different things from it.
A new programmer looks at what the video is “supposed” to teach and learns the immediate skill and how to do something in that language or environment.

Awhile back a fellow asked me the best way to increase test coverage at the small startup he works at.
It’s an excellent question.

For the entertaining version, listen to the podcast. For the just-the-facts extra-complete version, I’m...
You’ll often hear folks claim that it’s well-researched that some developers are ten times (or twenty-seven times! Or more!) as productive as the median developer. They often refer these gifted folks as “10x developers.”
