    @Microsoft Can you disappear? And kill all your fucking bosses so they will never work on anything again! EVERYTHING you created is fucking garbage! EVERYTHING you bought always becomes a garbage!

    The @github outage yesterday burned through all our GitHub Actions minutes because their internal package mirrors were super slow. Love getting penalized for something that wasn't our fault.

    The next simplecov version will include a new coverage mode - github.com/simplecov-ruby…. If you use code coverage on CI, you might see a big performance boost, as we had. Our CI runtime dropped from 15 minutes to 10 with this simple change 😱.

    Got the first million downloads for one of my gems! 🎉 It was my first gem, and it became the most used.

    If you use CircleCI, make sure to use blobless checkout. It reduced our checkout step from 1 minute to 20 seconds!🚀And it is used in quite a lot of places.

    Created a new gem to lazily load specified Active Record columns - github.com/fatkodima/acti… This can greatly reduce IO 📉 and improve queries (and application's) performance 📈if you have some large db columns that are not used most of the time.
