The Science of Expertise (Part I): Introduction to Perceptual Learning

How do you become an expert? Why some Ruby developers can’t explain what they know? Why some developers don’t develop expert skills? What does it mean to be a Ruby expert? To discuss these questions, we’ll explore Perceptual Learning (PL) research. PL is a natural learning process that complements traditional Education. It accelerates expertise by speeding pattern recognition, intuition and fluency on a given subject.

New job, new codebase. How do you even get started?

How to write Badass READMES for your Github projects

You show your GitHub project to people but they don’t understand what the code is about. Why should you take time to write a good README if they can simply “read the code”? They won’t even look at your code if you don’t explain what’s in it for them. Why should anyone care about it? What about making them curious about your project? It saves them time, it shows you care about good communication and that by writing good docs you probably write good code as well....

The Unstuck Guide for Developers

When you get stuck, it’s really easy to block yourself from creatively solving your problem.
