I recently had the chance to give my OOP-in-FP-in-Swift talk again in NSLondon, and was asked how to build inheritance in that object system. It’s a great question, I gave what I hope was a good answer, and it’s worth some more thought and a more coherent response. Firstly, let’s look at the type signature […]
I think the last technical conference I attended was FOSDEM last year, and now I’m sat in the lobby of the Royal Library of Brussels working on a project that I want to take to some folks at this year’s FOSDEM, and checking the mailing lists of some projects I’m interested in to find meetups […]
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 […]
[Note: this post represents the notes made for my talk at iOS Dev UK 2014. As far as I’m aware, the talk isn’t available on the tubes.] The Principled Programmer The first thing to be aware of is that this post is not about my principles. It’s sort-of about your principles, in a way. On […]
You would imagine that by now I would have come to realise how long my attention span is and worked to find projects that fit within it, but no. This is one of the changes I need to make soon. So often I start a project really excited by it, but am really excited by […]
Much is written about various paradigms or orientations of programming: Object- (nee Message-) Oriented, Functional, Structured, Dataflow, Logic, and probably others. These are often presented as camps or tribes with which to identify. A Smalltalk programmer will tell you that they are an Object-Oriented programmer, and furthermore those Johnny-come-latelies with their Java are certainly not […]
Take a look at your slides. For each slide, think how you would present the same information if you didn’t have the slide. Practise that, so that you can give the information on the slide without using the slide as an aide memoire. Practise that, until you can introduce that topic, discuss it, and move […]
I enjoyed Jaimee’s discussion of preparing her public talks, and realised that my approach has moved in a different way. I’ve probably talked about this before but I’ve also changed how I go about it. This is my technique, particularly where it diverges from Jaimee’s; synthesis can come later (and will undoubtedly help me!). I […]
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 […]
Here’s a design I’ve had knocking around my head for a while, and between a discussion we had a few weeks ago at work and Saul Mora’s excellent design patterns talk at QCon I’ve built it. A quick heads-up: currently the logic is all built into a side project app I’ve been working on so […]
