Breaking Up with Google Play: Why Conversations Is Now Free
Conversations, my federated instant messaging client for Android, started out as many traditional open-source projects do: as an attempt to scratch my own itch.

Building a new Windows 3.1 app in 2019: A Slack Client
In October 2019, my company SP Digital held an internal hackathon.

After all, Slack clients exist for most platforms but I’m certain one does…

The Polygons of Another World
There is a playful way to study the architecture of computers of the past. Find a piece of software you know well and try to find out how it was ported to these machine you don't. A good choice would be DOOM. id Software's 1994 mega-hit has been ported to everything. It is designed around a core with no layering…

Why software projects take longer than you think – a statistical model
Anyone who built software for a while knows that estimating how long something is going to take is hard. It's hard to come up with an unbiased estimate of how long something will take, when fundamentally the work in itself is about solving something.
