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 […]

Story points: because I don’t know what I’m doing

The scenario [Int. developer’s office. Developer sits at a desk that faces the wall. Two of the monitors on Developer’s desk are on stands, if you look closely you see that the third is balanced on the box set of The Art of Computer Programming, which is still in its shrink-wrap. Developer notices you and […]

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 […]

Representativeness in Software Engineering Research

The first paragraph describes the context of this post in relation to the blog on which it originally appeared, not For this post, I wanted to go a little bit meta. One focus of this blog will be on whether results from academic software engineering are applicable to the work I do as a […]

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”} […]

The code you wrote six months ago

We have this trope in programming that you should hate the code you wrote six months ago. This is a figurative way of saying that you should be constantly learning and assimilating new ideas, so that you can look at what you were doing earlier this year and have new ways of doing it. It […]

Lighter UIViewControllers

The first issue of Objective-C periodical has just been announced: Issue #1 is about lighter view controllers. The introduction tells you a bit more about this issue and us. First, Chris writes about lighter view controllers. Florian expands on this topic with clean table view code. Then Daniel explores view controller testing. Finally, in […]

APPropriate Behaviour is complete!

APPropriate Behaviour, the book on things programmers do that aren’t programming, is now complete! The final chapter – a philosophy of software making – has been added, concluding the book. Just because it’s complete, doesn’t mean it’s finished: as my understanding of what we do develops I’ll probably want to correct things, or add new […]

Specifications for interchanging objects

One of the interesting aspects of Smalltalk and similar languages including Objective-C and Ruby is that while the object model exposes a hierarchy of classes, consumers of objects in these environments are free to ignore the position of the object in that hierarchy. The hierarchy can be thought of as a convenience: on the one […]
