Mastering Low Level Caching in Rails
Sometimes when your app is slow, it’s not your fault. Your code might be optimized to the teeth, but it won’t matter if it has to perform intrinsically slow tasks, like fetching data from an external API. In these situations, Rails’ low-level caching can be a life-saver. But caching is infamously tricky. It’s dangerous to go alone. In this article, Jonathan Chase guides us through the landscape of low-level caching. He covers the basics, but more importantly, digs into essential details of cache invalidation and points out common pitfalls. https://www.honeybadger.io/blog/rails-low-level-caching/
monos - monorepo / mono source tree tools and (startup) scripts
Hello, I’ve put together the new monos gem that sports some little tools that let you manage monorepos / mono source trees (for ruby gems). It’s an early stage - for now the mono (or short mo) command line tool lets you run git commands on multiple repo(sitories) with a single command. Cheers. Prost.

Understanding Selection Sort with Ruby
If I asked you to sit down right now and sort a list of numbers, there’s a good chance that you’d intuitively rediscover the selection sort algorithm. It’s a simple approach that can have significant performance implications. That’s why it shows up so frequently in technical interviews - even though most developers never implement sorting from scratch. In this article, Julie Kent walks us through the selection sort algorithm, builds a working implementation in Ruby, and discusses its performance characteristics. https://www.honeybadger.io/blog/ruby-selection-sort/
