Move over Rake, Thor is the new King

Yes, Rake is certainly the heavyweight in this arena. But it is also clunky and has some oddities, and limitations that are frustrating to work around in day to day usage. Tools are always improving and we shouldn’t stick with something just because we always have. [more inside]

How I Write Code: Pen & Paper

Even though I love programming, I try not to sit in front of a computer screen too much. I do not find staring at a screen all day beneficial, not for my physical health, nor for my mental health. In the last few years, I’ve started a habit of sketching my programming ideas using pen and paper. I’m not talking here about todo lists, or making diagrams. I’m talking about actually writing code using pen and paper. Let me explain.

My Recipe for Optimizing the Performance of Rails Applications

Rails performance audits have been my main occupation and source of income for over a year now. In this blog post, I’ll share a few secrets of my trade. Read on if you want to learn how I approach optimizing an unknown codebase, what tools I use, and which fixes are usually most impactful. You can treat this post as a generalized roadmap for your DIY performance audit with multiple links to more in-depth resources. [more inside]

Rubber Duck Dev Show Episode 4 | Pair Programming - When, Why and How!

In this episode, we discuss the Why, When & How to Pair Program:

RSpec Tracer is a specs dependency analysis tool and a test skipper for RSpec

RSpec Tracer is a specs dependency analysis tool and a test skipper for RSpec. It maintains a list of files for each test, enabling itself to skip tests in the subsequent runs if none of the dependent files are changed. It uses Ruby’s built-in coverage library to keep track of the coverage for each test. For each test executed, the coverage diff provides the desired file list. RSpec Tracer takes care of reporting the correct code coverage when skipping tests by using the cached reports. Also, note that it will never skip any tests which failed or were pending in the last runs. Knowing the examples and files dependency gives us a better insight into the codebase, and we have a clear idea of what to test for when making any changes. With this data, we can also analyze the coupling between different components and much more. [more inside]
