Time and Relative Distance in Source (Code)

Reasoning about a program’s behavior is extremely tricky in the best of circumstances. When you throw in asynchronicity, it is the absolute worst. It’s like your code is trapped in a convoluted time travel movie. You want to perform some operation, but that requires stepping into a time portal and coming out at some indeterminate […]

Three Tips for Migrating from JavaScript to TypeScript

Over time, and especially in the past few years, the tech community has gotten sick of JavaScript and its loose typing. Trying to write a complicated program without static types is like driving at night without headlights—you’ll probably be fine for a while, but there’s a good chance you’ll crash a few times along the […]

Using Decorators to Declaratively Extend Functions

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 […]

GraphQL + Apollo – Part 1: An Introduction

This past September, I attended the Strange Loop conference in St. Louis. Among the plethora of great talks that I attended was one about GraphQL, given by Lee Byron. This talk, supplemented by a great deal of research, convinced me that I should use GraphQL in the project that I started a couple of months […]

Lazy Sequences with ECMAScript 6 Generators

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 […]

Pixels and Palettes: Extracting Color Palettes From Images

Color palettes are usually carefully hand-selected to reflect a desired design aesthetic. Although there have been some attempts to procedurally generate palettes, automated palette creation is very difficult. It’s easy to choose some random colors, but generating a coherent and aesthetically pleasing palette in an automated way is not easy.
