• What is property testing?

  Published Oct 23, 2023

  Property testing is a developmental approach to writing tests (both unit tests and integration tests) which helps developers find the limitations of their software. It isn't an all-encompassing set of principles or practices which impacts the whole development lifecycle, unlike Test Driven Development. Instead, it's isolated to the testing process, and it focuses on procedurally generating test inputs and then checking the properties of the output, rather than relying on a predefined list of "Input X gives Output Y." …

• Error Handling Across Programming Languages

  Published Sep 10, 2023

  One of the most frustrating yet fascinating facets of using a programming language is how it handles errors. Many of these error handling patterns include the traditional try/catch, error flags, unions, multiple return values, error paths, etc. These patterns are fascinating to investigate and see the various methodologies and practices languages and libraries have used to implement them. This is by no means an exhaustive list or investigation. Rather, it's a review of what I've personally experienced with error handling. …

• Stateless Logic

  Published Sep 9, 2023

  State is some form of "global" or "shared" memory. It allows code to "remember" or "know" something without having to be retold that fact every time. For instance, let's consider a simple count method which tracks how many times the method was called. Below is an example using state: …

• Separating SQL from code with files: Initial Thoughts

  Published Nov 28, 2022

  Recently I've been working on a side project (that may or may not get published publicly, I haven't decided yet). For this project, I decided I'd try a lot of new things, not all of which worked out as well as I thought (which may be why it stays private). I've tried a new Java/Kotlin framework, briefly tried a new JVM build system (and then went back to Maven), tried new control flow mechanisms, new error handling techniques, etc. It's been more of a playground for new ideas than a true product. …

• Predictions in Tech: Looking Forward from 2022

  Published Nov 11, 2022

  A lot has happened in the world this year. Most of the world has started to move past COVID-19, especially in the U.S., regardless of whether it's really gone. Russia has started a "special operations" (aka. military invasion) inside Ukraine, has had the war go fairly poorly for it, and is now trying to salvage what it can while hurting NATO and Ukraine as much as it can - especially when it comes to energy prices (aka. gas and oil). Elon Musk just bought Twitter, and it currently looks like the bird is on a hard crash course with the ground. Meta has revealed it's spent multiple billions of dollars in the metaverse. Mass layoffs in tech are starting to happen, and there's talk of a coming recession (or maybe a depression). That's also not mentioning the craziness in politics right now. …

• Why Care About Web Accessibility

  Published Oct 20, 2022

  For most people, websites are visual experiences. We see images, we read text, we move the mouse,scroll with our fingers, tap or click on buttons, etc. The only way most people change howthey interact with sites is by switching to another device, such as from a computer to aphone. …

• Introduction to Localization and Langauge

  Published Sep 27, 2022

  I first published this back in 2022. At the time, I was leading the localization effort of an English-only product. The product had existed for over a decade, and over time a lot of bad habits had crept up. This was the public (non-confidential) write-up I made on localization that I could use both internatally and externally. …

• Chains, Buckets, and Iteration

  Published Sep 20, 2022

  Back in high school, I worked on robots with a few other students. When we built our robots, we had motors and wheels that were a foot or two apart. To transfer the energy from our motor to our wheels, we used chains. …
