Lots of developers have side projects, but if you ask about them, they’ll probably say, “I’ve got a bunch of ideas and a few things in progress, but nothing I’ve finished.” It seems to be a common theme. Lots of interesting problems and big ideas, but not enough follow-through. A lot has been written about […]
Ruby makes it easy to extend its built-in classes, which can be very convenient and lead to more readable code—but it can also be dangerous. This practice, known as “monkey patching,” is common in the Ruby world, and since Ruby 2, it’s been possible to mitigate some of the risks using refinements.
A lot has been written about the benefits of functional programming, but little of it is accessible to a newcomer. Some of the benefits are easy to understand from an inexperienced perspective (e.g. “it makes concurrency easier”), but others are pretty nebulous. Chief amongst the inscrutable properties of functional programming is its “elegance.” It isn’t […]
“I hate reading other people’s code” is a common refrain among software developers of all experience levels. However, it’s a necessary skill, especially for developers rolling onto existing codebases, and if you approach it with the right perspective and the right tools, it can be an enjoyable and enlightening experience.
The decorator pattern gained fame in the object-oriented world after being featured in the classic 1994 Gang of Four book, Design Patterns. Since then, it’s been used extensively in traditional object-oriented programming as an alternative to inheritance. What’s really going on behind the scenes though, is composition, which means decorators are also great for cleaning […]
Generators are an ES6 feature that started receiving a lot of attention a few years ago because of their potential to ease some of the pain associated with writing asynchronous code. However, with the emergent async/await proposal (mere syntax sugar around generators and promises), some of the shine has worn off, and generators aren’t getting […]
