At XP Day 2008 I proposed an open-space session on pair programming. Specifically, I wanted to explore the reasons why programmers might not want to pair, or find it such an unpleasant experience that they’re put off doing it again. Judging by the great number of people who turned up and stayed for the session, …

Slides from XP Day Talk
I’m just back from this year’s XP Day, London. Thanks to everyone who came and packed out the room to hear Rob and I talking about our experiences evolving our team from Scrum to Kanban. The slides are here. There’s also a great transcript of the talk here on Tom Hume’s blog. Thanks Tom!
In Defence of class << self
I recently came across this blog post from the venerable Chris Wanstrath (of github / err the blog fame) which took me somewhat aback. Chris suggests that using class << self to contain class methods (C# / Java programmers read ‘static methods’) is a harmful habit that should be discouraged. I dislike class methods generally: …
DRY up your Cucumber Steps
Update (13th Jume 2012): This is an old, old post that still gets a lot of hits. I don’t recommend this practice anymore. Instead, I recommend composing Ruby methods that carry out these actions. For more details, please see The Cucumber Book. A while back, I asked the Cucumber team for the ability to call …
“Total Programming” and the XP Team
Pair programming brings a great many benefits to a team that’s truly mastered it. Those of us who are lucky enough to have experienced working on a really effective XP team know about that almost magical thing that starts to happen when the barriers between different members of the team break down, egos and code …

I am Extreme
I going to be speaking (with my good friend Rob Bowley) at the forthcoming XP Day conference in London, 11th & 12th December 2008. Which means that I am now officially extreme. Dude. Come to my talk if you want to hear my experiences of breaking a team out of the Scrum mould and doing …
Ubuntu Eee – The OS Your EEE Should Have Been Born With
On finishing a long contract and project at the BBC a few months ago, I was incredibly touched to be given a brand new Asus EEE PC as a leaving gift by my colleagues. Although I loved the tiny form factor and take it with me practically everywhere, I was never quite satisfied with the …

Logging HTTP Error Messages in Ruby and Rails
Rails comes with some default logging stuff built in, but if you’re used to the sophistication of the log4x frameworks, it’s pretty basic. One of my requirements is to be able to log exceptions that occur during an ActionController HTTP request, and have the configurable logging mechanism decide what to do with them – most …

Is the Value Fetish Killing Agile Teams?
Last weekend I was at CITCON Europe, a great opportunity to meet some of the leading minds in the agile software movement. One intriguing new term I heard a few times was “value fetish”. Let me try to explain what I think it means, and discuss the implications for agile teams.
