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. Ever since I found out about Perceptual Learning in the book “Badass - Making users awesome”, from Kathy Sierra, I got really curious to learn more about the science behind Perceptual Learning....

“Can you help me build out my developer portfolio?” It’s the first question early-career developers ask when they book a mentoring call with me. They’ve been struggling to find their first developer job. They read an article or a friend tells them they should be focusing on building their tech portfolio. Or they just decided to follow generic advice on the internet. I’ve been mentoring people for many years, and the portfolio question is the first thing they ask me....

Does it take forever to ship even small features on the codebase you’re working on? Is the code hard to understand and maintain? Are projects always running over budget? Are you constantly sacrificing code quality and not paying down technical debt? When you change one feature, does another completely unrelated part of your app stop working? New bugs appear, even though tests never break? 🥵 Those are signs that you are suffering from working on a codebase with low code quality....

Are you looking for courses, training, and resources to improve your Ruby and Ruby on Rails skills, but you are not being paid in US dollars? Most Ruby and Ruby on Rails books and courses are priced in US dollars.

Are you having a hard time picking up the syntax of a new programming language, even though you know how to code?

You want to write smooth professional-looking code. You’re craving some squeaky-clean code. But all you have for lunch every day is a big bowl of legacy spaghetti code.

One of my readers asked: How do you get started when you join a new company? How do you add features to a codebase that is massive, scary, and completely new to you? The first day at your new developer job is just like the first day at a new school. 🚸 A sea of stranger’s faces watching your every move. Unfamiliar smells in the hallway.

Let’s say you’re learning how to paint. When you look at the famous paintings at the museum, you might start asking yourself: “Will I ever be this good? Is this for me? Will I ever understand all of this?” If these questions sound familiar, it’s because you’re not alone. It’s not just you. Believe it or not, the same questions can be applied to coding. Some things, like painting and learning how to code, are hard....

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....

When you get stuck, it’s really easy to block yourself from creatively solving your problem. You start asking “why am I so dumb?”, or thinking that you don’t have a programmer’s brain, or feeling that you’ll never understand anything. How is that helpful? It isn’t. The way we talk to each other (even to ourselves) impacts our performance. It’s not self-help BS. It’s how our brain works. As Dr. Lisa Feldman Barrett, one of my favorite neuroscientists, shows in this short video, “The Power of Words is in the wiring of your brain”:...

You have a technical blog but there is only one problem: no one is reading what you write. Why? Think about it: readers aren’t going through their day waiting for your tech tutorials.

When you’re banging your head against the wall trying to fix a bug, the last thing you want is having to stop and learn how to use the debugging tool.
