Ergonomic TypeScript Generics with Higher-Order Functions

Much of TypeScript’s flexibility comes from its support for generics. They’re great for building up reusable abstractions so that you can share the “how” across your codebase even as the “what” varies significantly. In this post, I’ll describe a limitation that recently got in my way, and how I worked around it.

Docker Volumes: Why, When, and Which Ones?

Docker volumes are used to persist data from within a Docker container. There are a few different types of Docker volumes: host, anonymous, and, named. Knowing what the difference is and when to use each type can be difficult, but hopefully, I can ease that pain here.

Using attributedText to Create a Single UILabel with Multiple Styles

This approach lets you style strings without changing the style on the label directly. Below is a step-by-step guide for how to […]

JavaScript-free Web Development with WebAssembly, Bolero, and F#

A while back, I remember hearing about WebAssembly and how it would finally release the web from the grip of JavaScript. (Languages that transpile to JavaScript don’t cut it). Although WebAssembly doesn’t make the news much these days, it turns out there is quite a bit of work being done in this area. Since I […]

BLOBs with Knex and PostgreSQL

My team and I recently decided that we should store user-generated binary files in our PostgreSQL database so that a user could download them at a later time. This is different from uploading those files to something like Amazon S3 (which we’ll likely consider migrating to at some point down the road).

A Gentle Introduction to Local Development with Docker Compose

Getting started with Docker can be a bit overwhelming. There are images, containers, Dockerfiles, docker-compose, etc. In this post, I’ll give a quick introduction to using docker-compose with PHP and MySQL.

Data Binding with Live Data for RecyclerView in Kotlin

When working on an app in Kotlin or Android, it’s very common to use RecyclerViews to display lists of information. Typically, this data will be built up in ViewModels and passed to a list adapter. This works fine for most things and allows interaction with the items. Usually, they don’t need to change directly in […]
