All the things

It’s been a long time since I had a side project, or one that didn’t get abandoned very early on. I tend to get sidetracked by other thoughts about computing, or think “while I’m doing this, I’m leaving that unsolved” so nothing gets very far. In an attempt to address that, to clear all of […]

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, […]

Recommend me some books or articles

I’ve been looking for something to read on these topics, can you help? a history of the Unix wars (the ‘workstation’ period involving Sun, HP, Apollo, DEC, IBM, NeXT and SGI primarily, but really everything starting from AT&T up to Linux and OS X would be interesting) a business case study on Apple’s turnaround 1997-2001. […]

On books

I’d say that if there’s one easy way to summarise how I work, it’s as an information focus. I’m not great at following a solution all the way to the bitter end so you should never let me be a programmer (ahem): when all that’s left is the second 90% of the effort in fixing […]

Working Effectively with Legacy Code

I gave a talk to my team at ARM today on Working Effectively with Legacy Code by Michael Feathers. Here are some notes I made in preparation, which are somewhat related to the talk I gave. This may be the most important book a software developer can read. Why? Because if you don’t, then you’re […]

On the extremes of computer science

I didn’t study computer science at school or university, and still manage to work as a programmer. That is not to say that I don’t need to know some things that are taught on computer science courses. Just this week I’ve had to build a couple of different data structures and understand their running time: […]

Staying power

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 […]

It depends? It depends.

Sometimes you ask a question which has a small collection of actionable answers: yes or no. You ask someone who should be able to give that yes or no answer, and they go for the third: it depends. Maybe they can’t actually answer your question, but want to sound profound. Maybe they don’t realise that […]

That can’t possibly work.

A while back I was at a Facebook developer event, talking about techniques for analysing Objective-C. My summary of the problem was something like “it’s one of those things that works pretty well in the ivory towers of practice but completely falls apart when you try to use it in theory.” That’s true of many […]

Fuck. This. Shit.

Enough with the subtle allusions of the previous posts. What’s going on here is not right. It’s not right that I get to pass as a member of the group of people who can work in technology, while others have to justify their very presence in the field. It’s not right that “looking like me” […]
