Architecture and urban planning have been a useful source of ideas for thinking about programming. I have written various blog posts and a paper Programming as Architecture, Design, and Urban Planning that argue why and explore some of those ideas. Like urban planning and architecture, the design of any interesting software system deals with complex problems that can rarely be analysed in full and with structures that will continue to evolve in unexpected ways after they are created. My most recent reading[...]

Figure 1. The Timeless Way of Building - Christopher Alexander Many programmers know the name of the architect Christopher Alexander for his work on design patterns that has been adapted into the world of programming. A lot of people know of the, sometimes ridiculed, patterns like strategy (functions!) or visitor (pattern matching!) and some have read the Gang of Four design patterns book that introduced them. A few people know of the Patterns of Software book by Richard P. Gabriel, which is a much more[...]

Figure 1. Virtually eliminates your coding load. FLOW-MATIC promotional brochure (1957) No-code is a hot new topic for programming startups. The idea is to develop a system that allows end-users to do the programming they need without the difficult task of writing code. There are no-code systems for building mobile apps, analysing data and many more. It is perhaps not a surprise that "eliminating programming load" is not as new idea as some people may think and there is an excellent blog series on no-co[...]

I started to learn how to program in high school at the end of the 1990s using a mix of BASIC, Turbo Pascal and HTML with JavaScript. The seed for this blog post comes from my experience with learning how to program in JavaScript, without having much guidance or organized resources. This article continues a theme that I started in my interactive Commodore 64 article, which is to look at past programming systems and see what interesting past ideas have been lost in contemporary systems. Unlike with Commodor[...]

While the physicists investigate the nature of the mysterious portal that has recently appeared in North London, several human beings recently came through the portal, which appears to be a gate into an alternative universe. As we understood from the last two people coming through the portal, it seems to be a linked with a universe that is in many ways like ours, reached about the same level of social and technological development, but differs in numerous curious details. The paths through which people in [...]
