    Flipper is already pretty optimized for production usage (flipper does billions of feature checks a day at GitHub), but the latest release (0.10.2) just received a couple new ones — all thanks to community contributions. In jnunemaker/flipper#190 , @mscoutermarsh said: Hi, Would love ...

  • Flipping ActiveRecord

    railstips.org 23 Dec '15, 2am

    Originally, I did not like the idea of an ActiveRecord adapter for Flipper . I work on GitHub.com day to day, so everything I do has to be extremely performant. Using ActiveRecord for something like this felt like way too much overhead. In fact, at GitHub, we use a custom adapter for ...

  • Four Guidelines That I Feel Have Improved My Code

    railstips.org 05 Jul '12, 7pm

  • Let Nunes Do It

    railstips.org 18 Apr '13, 8pm

    In a moment of either genius or delirium I decided to name my newest project after myself. Why? Well, here is the story whether you want to know or not. Why Nunes? Naming is always the hardest part of a project. Originally, it was named Railsd. The idea of the gem is automatically sub...

  • Of Late

    railstips.org 24 Feb '14, 7pm

    A lot has changed over the years. I now do a lot more than just rails and having railstips as my domain seems to mentally put me in a corner. As such, I have revived johnnunemaker.com . While I may still post a rails topic here once in a while, I’ll be posting a lot more varied topics...

  • More Tiny Classes // RailsTips by John Nunemaker

    My last post, Keep ’Em Separated , made me realize I should start sharing more about what we are doing to make Gauges maintainable. This post is another in the same vein. Gauges allows you to share a gauge with someone else by email. That email does not have to exist prior to your add...
