Algebraic data types and algebraic data structures sound similar. It’s like they ought to be the same thing. But they’re not. They both have ‘algebraic’ in the name, so it’s confusing. I got them mixed up at times. Others have too. But, they’re different concepts. Understanding the difference will help if you’re…
How our mind falls short trying to short cut.
Last month, Google announced that its Nest Secure would be updated to work with Google Assistant software. The problem? Google never told users its product had a microphone to begin with. Simple oversight or invasion of privacy? We break it down.

I've spent a week cosplaying as a disabled user. And I hate it. A couple of months ago, I attended a private talk given by a disabled colleague of mine. "Everyone should believe disabled people's stories about accessibility problems," she said. "But, given that people don't, here's what I want you to do. Spend one…
In February 2018, my wife & I decided to embark on a gruelling quest: to watch all three Lord of the Rings films (extended editions, of course), while attempting to eat everything that got eaten on screen.

I've been enjoying using Go's database/sql package for working with databases. Recently, some mentions of gorm piqued my curiosity about using ORMs in Go vs. using database/sql directly. Having had some mixed experiences with ORMs in the past, I decided to start with a practical experiment by writing the same simple…
One of the anonymous reviewers of my recently published Storage Combinators paper ( pdf ) complained that hiding disk-based, remote, and lo...
One time I had a “great” idea for a telephone company. Service would be free—all the calls you want! But you’d have to listen to advertisements before each one. I asked my friend what he thought the idea was worth. His answer: “I don’t know. Telephone companies make a lot of money. Maybe $1 billion?” […]
How we migrated our Tier 1 service from ruby to rust and didn’t break production.

When I catch a bug before release I’m usually glad, because I’ve narrowly averted ruining someone’s experience or eating their data. Today I found a bug that I wish I hadn’t caught, a bug that I wish I’d released into the wild to witness in its full glory. I found this bug in my digital card game Ring of Worlds, and…
Data is being gathered and created at rates unprecedented in history. Much of this data is intended to drive business outcomes but, according to the Harvard Business Review, “…on average, less than half of an organization’s structured data is actively used in making decisions…” The root of the problem is that data is…

This marks the beginning of a week long adventure in Geneva Switzerland at CERN, to work on a hack project.
Almost every one of you must have written a program, compiled it and then ran it to see the fruits of your hard labour. It feels good to finally see your program working, isn’t it? But to make all of this work, we have someone else to thankful too. And that is your compiler (of course, assuming that you are working in…
Elixir v1.8 comes with many improvements at the infrastructure level, improving compilation time, speeding up common patterns, and adding features around introspection of the system.
I first started using Python in 1993. It's been my main programming language since about 2000. I've written a ton of code in Python, both for work and in my free time. For several years now, I've been growing dissatisfied with it. Partly it's because I'd like more help from my programming tools, such as static type…
