For someone who is new to text editors and the terminal – the installation process can be really overwhelming.

  What's on your Learning List?

How do you track and decide what topics you want to spend time learning? For a while, I didn’t have a real good solution. Something would trigger me to remember “Oh yeah! I really wanted to learn more about that”. I would spend the evening doing busy learning - it seemed like I was learning but I really wasn’t. Instead of trying to do Deliberate Practice, I’d fool myself into thinking I was investing my time wisely by reading blog posts and examples but no...
