The 30-Day Code Quality Challenge

A free, language-agnostic exercise of will.

Tiny wins, every day.

I've worked on a lot of codebases over the years, and I've discovered a recurring truth:

A steady drum-beat of small quality wins beats occasional large efforts every time.

Big-bang improvements are hard to schedule, difficult to justify, less fun, and don't work as well.

That's why I created this challenge.

Every work day (Mon-Fri), you'll receive a small exercise whose completion will improve the quality of the codebase you work on.

Your job is to implement the change and report your experience back to the group. We'll support each other through the challenges, and celebrate our victories.

Facts, for your perusal:

  • The course is free.
  • The exercises are language-agnostic.
  • Each exercise takes 20 minutes.
  • Completing an exercise improves your codebase.

What do the exercises look like?

Something like this:

  • Run your test suite with the wifi off and see what fails.
  • Grep your codebase for TODO comments. Delete them or create tickets in your issue tracker.
  • Make something immutable that wasn't before.
  • Do something small to clean up that nasty file. You know the one.

“In this course @r00k will give you a whole series of good ideas and you'll turn those ideas in to better code. For me, this worked in both Go and Ruby and I suggest you give it a try!”

“Developer friends, check out @r00k's Code Quality Challenge. Our team completed it recently, and it was an awesome experience. We improved our codebase(s) a little bit each day, and learned a ton doing it.”

Never took the time to follow an online “thing”, but @r00k’s 30 Day Code Quality Challenge was a pleasant experience. Awesome community and great ideas to improve your app's codebase.

Hi, I'm Ben Orenstein!

I've spent the last 10 years mildly obsessed with code and how to make it better.

Currently, I'm building Tuple, an app for remote pair programming.
