   I remember very vividly the first time I listened to Daft Punk. I was maybe 16 years old (circa 2003) and was one of the first times I was traveling without my parents. I was on a skydiving trip with my instructor and crew. At night, there

   I used to love OSX for the same reason, but it's insane how much we've lost in this regard. Take Photos for instance; I simply can't drag a picture into a browser anymore; it forces me to drag a picture into the desktop, so t

   And what about an MRI? This website lists rates around 2k USD, while in Brazil you can get one (in high-end modern hospitals in São Paulo) for around R$ 600 (== $120).

   I changed database.yml to use 10 connections. I didn't change the Sidekiq configuration, which still uses concurrency: 25. Strangely, tonight I've seen the first exceptions like `ActiveRecord::ConnectionTimeoutError: could not obt

   Great article! We have a Rails app that uses Puma with MySQL, but so far single threaded (the Puma config has `threads 1,1`), because we migrated from Unicorn and are still worrying about thread-safety. Currently our database.yml pool size

   There's a great Veritasium video explaining the Magnus effect and the Flettner rotor here: https://www.youtube.com/watch?v=2OSrvzNW9FE The Norsepower company (which installs Flettner rotors on ships) also has a short v

   You are correct and the page is wrong. To calculate churn you simply divide the number of churned customers by the number of those customers you had at the beginning of the period. Note I mentioned "those" customers, because you n

    I've been using Sorbet for a while integrated in my SublimeText. I have never added a type signature, not even once. I just use it to prevent me from silly mistakes (like changing a variable name somewhere and breaking code downstream)

    Great article. Just one small tip: instead of using the BigDecimal("123.45") notation, I much prefer typing 123.45.to_d. Anywhere you used Floats, you can just replace them with BigDecimals. They work just the same. Some people ge

    I love Ansible, and we migrated our Rails deployment from Chef to Ansible. Now we have a subfolder /ops in our project that contains all the code to provision our infrastructure and deploy our app. However, I still find it very hard to

    This works wonders, and I first learnt about this approach in the Atomic Habits book [0]. I highly recommend it. I can list at least ten good daily habits that I have developed after reading the book, like doing 2 sets of pull-ups every mor

    Strongly disagree. Very been a customer for years before DO was launched. I've always benchmarked the same apps under the same load in both of them over the years and Linode has beaten DO every single time. Never had any issues with th

    I'm also not a fan of spending this syntax card on this feature. The ... => ... syntax might be needed for something more useful in the future.

    We do the same. The page loads with a div containing something like: `<%= content_tag :div, data: { behavior: 'vue_app', 'initial-data': { some: 'json' } %> <html spinner> <% end %>`

    I'm also very excited for Sorbet. Not because of types specifically (I don't use them and don't plan to), but because I hoped it would give me the same linting experience that ESLint gives me on JS files (unused variables, un

    This. We have very complex business logic directly tied to our Rails / ActiveRecord validations (and, btw, they are a blessing). Also, it's not only validations. We rely heavily on ActiveRecord callbacks, which are awsome. We have

    If you're using delayedjob, I strongly suggest you check out the Performance table in Sidekiq's readme. 465 seconds for DelayedJob against 14 seconds for Sidekiq for the same workload. It's 7100 jobs/sec x 215 jobs/

    I have explored the Node ecosystem/frameworks and Python/Django, but I still wouldn't trade Rails for anything.
