’Twas brillig, and the slithy git repos
Did gyre and gimble in the wecks:
All mimsy were the borogoves,
And the mome raths Mutex.

“Beware the legacy code, my son!
The classes that bite, the patches that catch!
Beware the Gemfile.lock, and shun
The frumious monkey patch!”

The Selfish Programmer

Using Ruby at work is great… but sometimes it feels like a job!

This year, I rediscovered the joy of writing Ruby apps for nobody but myself—and you should, too! Solo development is a great way to learn skills, to find inspiration, and to distill what matters most about programming.

Building an entire app by yourself can be overwhelming, but this talk will make it easier. We'll start with a minimal toolset that one person can maintain. You'll learn how many "bad" coding practices can actually reduce complexity. You may be surprised how selfish coding can make you a better team member, too!
