GNUstep is more important now than ever

In creating a pull request for GNUstep-base, the Free Software implementation of the Foundation library from Objective-C, I realised that if there was ever a time for GNUstep, now is it. Although GNUstep may have been envisaged as an official desktop for the GNU system – a role now fulfilled by GNOME – it has […]

On the lesser presentations

Advice on presentations – including that given on this blog, is often geared toward the “showbusiness” presentation. We’re usually talking about the big conference talk or product launch, where you can afford to put in the time to make a good, slick performance: a few days of preparation for a half-hour talk is not unheard […]

Why are you using the wrong licence?

I frequently see posts/articles/screeds asking why people don’t contribute to open source. If it’s important that recipients of open source software contribute upstream, and you are angry when they don’t, why use licences like MIT, Apache, GPL or BSD that don’t require upstream collaboration? Back in the day, Apple released their public source code under […]

The Atoms of Programming

In the world of physics, there are many different models that can be used, though typically each of them has different applicability to different contexts. At the small scale, quantum physics is a very useful model, Newtonian physics will yield evidently incorrect predictions so is less valuable. Where a Newtonian model gives sufficiently accurate results, […]

Stop ignoring the world

Long term readers will have noticed, and everybody else is about to be told, that this blog has had posts in the Responsibility category since 2010. I’m not rigorous in my use of WordPress categories, but it’s not much of a stretch to assume that most of those 40 posts touch on professional ethics, and […]

OOP as an organic approach to computing

I’m reading How Not to Network a Nation, which talks a lot about cybernetics. Not merely cybernetics as the theory of control in complex systems (cybernetics shares a root with “governor”, fans of the etymological fallacy!) but cybernetics as the intersectional discipline matching organisational and management theory with computer science, anthropology, and biology. The study […]

My platform is no platform

I currently use three of the desktop computing platforms (Windows, macOS and GNU/Linux) and one of the mobile computing platforms (Samsung-flavoured Android); I currently get paid to develop software for “the web”, an amorphous non-platform that acts in many ways like a vendor platform orthogonal to those just mentioned. This is not because I want […]

In which new developer tools are dull

Over on I said that I don’t hold out much hope for another “blue plane” style event in developer tools. In one of Alan Kay’s presentations, he referred to the ordinary way of things as the pink plane, and incremental advances in the state of affairs being movements in that plane. Like the square […]

Bottom-up teaching

We’re told that the core idea in computer programming is problem-solving. That one of the benefits of learning about computer programming (one that is not universally accepted) is gaining the skill of problem decomposition. If you look at real teaching of computing, it seems to have more to do with solution composition than problem decomposition. […]

Why I don’t have a favourite programming language

This is my take on Ilya Sher’s similar post, though from a different context. He is mainly interested in systems programming, I have mostly written user apps and backend services, and also some developer tools. I originally thought that I would write a list of the languages and difficulties I have with them, but I […]
