Random Thoughts: Measuring Technical Debt

This is a rambling-about-random-thoughts post. It goes a little out there. Have fun! This post was triggered by the Lean Code talk at #xp2017, by Desmond Rawls (@okokillgo) Using Lean Startup principles to improve code quality. Nick was using the normal code quality metrics for this. That is good, but: not all that actionable, and … Continue reading Random Thoughts: Measuring Technical Debt

Top Gear: A New Refactoring Kata

For the last five or six years, I've been using coding exercises during job interviews. After talking a little with a candidate I open my laptop, call up an editor, and we sit together to do some coding. My favourite exercise for this is a refactoring kata that I came up with. I've always found … Continue reading Top Gear: A New Refactoring Kata

Don’t Refactor. Rebuild. Kinda.

I recently had the chance to speak at the wonderful Lean Agile Scotland conference. The conference had a very wide range of subjects being discussed on an amazingly high level: complexity theory, lean thinking, agile methods, and even technical practices! I followed a great presentation by Steve Smith on how the popularity of feature branching … Continue reading Don’t Refactor. Rebuild. Kinda.

Agile 2015 Talk: Don’t Refactor. Rebuild. Kinda.

Monday, August 3, I had the opportunity to give a talk at the Agile Alliance's Agile 2015 conference in Washington, D.C. My first conference in the US, and it was absolutely fantastic to be able to meet so many people I'd only interacted with on mailing lists and twitter. It was also a huge conference, … Continue reading Agile 2015 Talk: Don’t Refactor. Rebuild. Kinda.

Outside in, whatever’s at the core

I haven't written anything on here for quite a while. I haven't been sitting still, though. I've gone independent (yes, I'm for hire!) and been working with a few clients, generally having a lot of fun. I was also lucky enough to be able to function as Chet's assistent (he doesn't need one, which was … Continue reading Outside in, whatever’s at the core

DevOps and Continuous Delivery

If you want to go fast and have high quality, communication has to be instant, and you need to automate everything. Structure the organisation to make this possible, learn to use the tools to do the automation. There's a lot going on about DevOps and Continuous Delivery. Great buzzwords, and actually great concepts. But not … Continue reading DevOps and Continuous Delivery

Spikes, they’re sharp

One of the concepts that came from XP is the Spike. Especially in teams new to agile, there can be confusion on what a Spike is, and how to deal with them. The best definition of a Spike I've found is this one: "Spike" is an Extreme Programming term meaning "experiment". We use the word … Continue reading Spikes, they’re sharp

Unit Testing JavaScript with QUnit and Mockjax

I've been experimenting a bit with JavaScript. My lack of real knowledge of the language, apart from some simple DOM-manipulations, is starting to become embarrassing! So a couple of months ago I decided I should pick up the JS axe, and do some chopping. And the first step to guiding yourself into any new programming … Continue reading Unit Testing JavaScript with QUnit and Mockjax

XP is Classic Rock

A while back I had a little fun comparing Agile to Rock'n'Roll. It's still one of my favourite posts, and after my recent talk on the benefits of TDD, I got the idea that the best follow-up on that is something about the XP practices. Test Driven Development with Bonnie Riatt The first artist that … Continue reading XP is Classic Rock
