Is Design Dead? (2004)
The rise of agile methods (particularly XP) makes some people wonder if there's any role left for software design. I argue that this change shifts from planned to evolutionary design.

Vale's first prototype for immutable region borrowing
Three years, two states, and one pandemic ago, I wrote about a very weird idea: what if the type system could track which data existed before a pure call, to eliminate its memory safety overhead? 0

Storing Data in Control Flow
A decision that arises over and over when designing concurrent programs is whether to represent program state in control flow or as data. This post is about what that decision means and how to approach it. Done well, taking program state stored in data and storing it instead in control flow can make programs much…

Emacs GUI Library
Lately, my Magit buffer broke once again because of something weird going on with major mode, and I couldn’t stash or commit hunks unless the point was at the beginning of the line. That once again reminded me that Emacs UI is not really a UI, all of it is mere text with a bunch of properties slapped on top.

The controller pattern is awful, and other OO heresy (2013)
Almost a year ago now, Jack Diederich gave a talk entitled “Stop Writing Classes“, in which he implores Python programmers to stop creating classes just for the hell of it, and specifically calls out the common pattern of a class with only a constructor/initializer and a single method—which should, of course, just be…

Resilience requires helping each other out
A common failure mode in complex systems is that some part of the system hits a limit and falls over. In the software world, we call this phenomenon resource exhaustion, and a classic example of th…

How small is the smallest .NET Hello World binary?
Here is a dumb question that you probably never asked yourself: What is the minimal amount of bytes we need to store in a .NET executable to have the CLR print the string"Hello, World!" to the standard output?

How to keep lambda calculus simple
Once upon a time, my curiosity of dependent types transitioned into an endeavour to learn how they work under the bonnet. Then I found the paper called “A Tutorial Implementation of a Dependently Typed Lambda Calculus” or just “Simply Easy” – and began reading it. However, the affairs happening there were so complex…

Goroutines: The concurrency model we wanted all along
Goroutines are the single feature that distinguishes Go from other languages. They look very much like threads, but they are cheap to create and manage. Go's runtime schedules goroutines onto real threads efficiently so you can easily create lots of goroutines.
