Preparing for Computing’s Big One-Oh-Oh

However you slice the pie, we’re between two and three decades away from the centenary celebration for applied computing (which is of course significantly after theoretical or hypothetical advances made by the likes of Lovelace, Turing and others). You might count the anniversary of Colossus in 2043, the ENIAC in 2046, or maybe something earlier […]

Intuitive is the Enemy of Good

In the previous instalment, I discussed an interview in which Alan Kay maligned growth-restricted user interfaces. Here’s the quote again: There is the desire of a consumer society to have no learning curves. This tends to result in very dumbed-down products that are easy to get started on, but are generally worthless and/or debilitating. We […]

How much programming language is enough?

Many programmers have opinions on programming languages. Maybe, if I present an opinion on programming languages, I can pass off as a programmer. An old debate in psychology and anthropology is that of nature vs nurture, the discussion over which characteristics of humans and their personalities are innate and which are learned or otherwise transferred. […]

On too much and too little

In the following text, remember that words like me or I are to be construed in the broadest possible terms. It’s easy to be comfortable with my current level of knowledge. Or perhaps it’s not the value, but the derivative of the value: the amount of investment I’m putting into learning a thing. Anyway, it’s […]

ClassBrowser: warts and all

I previously gave a sneak peak of ClassBrowser, a dynamic execution environment for Objective-C. It’s not anything like ready for general use (in fact it can’t really do ObjC very well at all), but it’s at the point where you can kick the tyres and contribute pull requests. Here’s what you need to know: Get […]

A sneaky preview of ClassBrowser

Let me start with a few admissions. Firstly, I have been computering for a good long time now, and I still don’t really understand compilers. Secondly, work on my GNUstep Web side-project has tailed off for a while, because I decided I wanted to try something out to learn about the compiler before carrying on […]

Updating my ObjC web app on git push

I look at SignUp.woa running on my Ubuntu server, and it looks like this. That title text doesn’t quite look right. $ open -a TextWrangler Main.wo/Main.html $ make $ make check $ git add -A $ git commit -m “Use new main page heading proposed by marketing” $ git push server master I refresh my […]

Automated tests with the GNUstep test framework

Setup Of course, it’d be rude not to use a temperature converter as the sample project in a testing blog post. The only permitted alternative is a flawed bank account model. I’ll create a folder for my project, then inside it a folder for the tests: $ mkdir -p TemperatureConverter/test $ cd TemperatureConverter The test […]

Conflicts in my mental model of Objective-C

My worldview as it relates to the writing of software in Objective-C contains many items that are at odds with one another. I either need to resolve them or to live with the cognitive dissonance, gradually becoming more insane as the conflicting items hurl one another at my cortex. Of the programming environments I’ve worked […]

At the old/new interface: jQuery in WebObjects

It turns out to be really easy to incorporate jQuery into an Objective-C WebObjects app (targeting GNUstep Web). In fact, it doesn’t really touch the Objective-C source at all. I defined a WOJavascript object that loads jQuery itself from the application’s web server resources folder, so it can be reused across multiple components: jquery_script:WOJavaScript {scriptFile=”jquery-2.0.2.js”} […]
