If you’ve been in software development for a while, you know that small web applications are ill-suited for massive load. I’m writing this a few days after Black Friday in the US. This year, another large retailer had a site outage, losing tens of millions of dollars in expected sales. The retailer definitely didn’t have a small system, but . . .
I can’t recall when I first heard Nick Bostrom’s Simulation Argument, but I know that it was a long time ago. It seems to resurface in the popular consciousness every few years — often when it is tied to the plot of a movie, or when a celebrity or entrepreneur makes reference to it.
The core of the argument can be found in the . . .
Modeling The Dynamics Of Code And Attention
In conversations about software development, I often ask people whether they’ve heard of Conway’s Law. It’s a doorway to a richer conversation. We can talk about the dynamics of design — how our environment affects us as designers and how the things that we design become part of that environment in a broad feedback loop. Without this . . .
Exploring Structural and Behavioral Abstraction
I’m fascinated by correspondence — when we see the same pattern in more than one place, or even a very different domain. A good example is Postel’s Law, sometimes known as The Robustness Principle. It states that when you are designing components in software you should design them so that they are open to accepting many kinds of input yet . . .
One of my favorite essays from the early 2000s is Clay Shirky’s A Group Is It’s Own Worst Enemy. It describes a dysfunction of on-line communities that is very familiar to us now in the age of social media.Communities often start as free spaces, but eventually chaos and harassment appear. Once they do, quite a bit of the group’s activity . . .
What can we do when we glitch?
How do you think?
It’s an odd question.
People think about thinking all of the time but they seldom talk about how ideas come to them. To the extent that I’m aware of my own process, I recognize that there’s a strong visuospatial component to my thinking. In my mind’s eye I see colors and shapes. When someone is talking, . . .
Growing Through Refactoring
These are interesting times for people who care about refactoring. The 2nd edition of Martin Fowler’s book Refactoring has just been released. As if that weren’t enough, Kent Beck recently wrote up a workflow called test && commit || revert, which can be seen as a new alternative to Test-Driven Development.
