VisualChannel

At the end of the 1990's I made a personal push-back against using slides in presentations, as I was tired by poorly designed bullet-points presentations. For around a decade, I gave keynotes with no slides at all. In the last year or so I've started using slides again - primarily inspired by watching my colleague Neal Ford who turns the dreaded slide-deck into a genuine enhancement to his talks (and is collaborating on a book project to pass on his techniques). As I've been working with slides again, I've also been thinking about what makes a set of slides an effective part of a talk. Thee main principle I've tried to follow is to think of them as a visual channel that complements the audio channel which is my spoken words. I find that thinking them of separate channels in this way helps me avoid common problems with presentations - many of which are rooted in the commonplace bullet point slides.

MotionGraphics

As I've been using slides again as a visual channel in my talks, I've been making use of animation with diagrams to help communicate my points. The major presentation programs (Keynote and Powerpoint) have long supported animation, but I've been inclinded to look for motion grahics tools that are more powerful and easier to use.

UtilityVsStrategicDichotomy

One of the steady themes I've seen throughout my career is that of the nature and importance of software development. Recently a prospect told one of our salespeople that "software is like sewage pipes, I want it to work reliably and I don't want to know about the details". This is the kind of approach that Nicholas Carr talked about in IT Doesn't Matter. On a contrasting note we've done work for many businesses where IT has been a clearer strategic enabler to their business, allowing them to enter new markets or significantly increase their market share. So is IT a utility, like sewage pipes, or a strategic asset?

iPad

I've not seen myself as an iFanboy. I didn't get an iPhone for ages after it came out, and only got one because it was the only way to upgrade my data plan to 3G. I use a mac, but I also have an Ubuntu desktop. But I have got an iPad, and I think it's a significant product.

Semat

SEMAT (Software Engineering Method and Theory) is an effort initiated by Ivar Jacobson, Bertrand Meyer, and Richard Soley. Its stated aim is to "refound software engineering based on a solid theory, proven principles and best practices". Like many notorious people in the software world I was invited to participate. Thus far I've declined and feel the need to explain why.

Richardson Maturity Model

A model (developed by Leonard Richardson) that breaks down the principal elements of a REST approach into three steps. These introduce resources, http verbs, and hypermedia controls.

ToyotaFailings

One answer for this is to take a sense of proportion. Lean manufacturing techniques were the underpinning of Toyota's rise from an insignificant company in the 1950's to a global giant in the 2000's. By the 1990's other car companies, and many other manufacturers, were busily copying Toyota's techniques. The general sense is that copying these techniques did much to raise the overall quality of cars in the last decade or so. I would be very surprised if the recent problems at Toyota are enough negate that half-century of success.

VersionControlTools

If you spend time talking to software developers about tools, one of the biggest topics I hear about are version control tools. Once you've got to the point of using version control tools, and any competent developers does, then they become a big part of your life. Version tools are not just important for maintaining a history of a project, they are also the foundation for a team to collaborate. So it's no surprise that I hear frequent complaints about poor version control tools. In our recent ThoughtWorks technology radar, we called out two items as version control tools that enterprises should be assessing for use: Subversion and Distributed Version Control Systems (DVCS). Here I want to expand on that, summarizing many discussions we've had internally about version control tools.

ReproducibleBuild

One of the prevailing assumptions that fans of Continuous Integration have is that builds should be reproducible. By this we mean that at any point you should be able to take some older version of the system that you are working on and build it from source in exactly the same way as you did then.

SnowLeopard

I've been intending to upgrade my laptop to Snow Leopard for ages. Particularly once I got Aperture 3, which I'm told works better. But I never quite got around to it, after all operating system upgrades are usually such a pain. (Although Ubuntu upgrades are much less painful than most.)

FeatureToggle

One of the most common arguments in favor of FeatureBranch is that it provides a mechanism for pending features that take longer than a single release cycle. Imagine you are releasing into production every two weeks, but need to build a feature that's going to take three months to complete. How do you use Continuous Integration to keep everyone working on the mainline without revealing a half-implemented feature on your releases? We run into this issue quite a lot and feature toggles are a handy tool to deal with it.

Agile2010

Last week I attended the Agile 2010 conference in Orlando. Agile 20xx is the major US agile-oriented conference whose roots go back to XP Universe and the Agile Development Conference. I've not been a regular attender of the main agile conferences, but I did go last year as well. Rather than make an attempt at a consolidated description, here are a few scattered impressions.

TeamRoom

A common thing you find in agile projects is that the development team sits in a single open team room. It was advocated early on in Extreme Programming and called out as one of primary practices in the second edition. Agilists favor a open team room as it promotes lots of informal and deep communication between people on the team.

Pourquoi, pas comment

Neal Ford and Martin Fowler

Neal Ford and I gave a talk at USI in Paris (2010) on some aspects of why agile works (as opposed to how). This probes at some of the core forces that makes agile effective, rather than looking at techniques. In particular we look at role of communication and feedback and how they interplay in agile environments.

CanonS90

Like many obsessive snappers, I've recently got hold of the Canon S90 camera. It's small enough to fit in your pocket, but has the kind of things that people with pretensions to seriousness like: full manual controls, RAW file support, a good sensor, and an f2 lens.

VcsSurvey

When I discussed VersionControlTools I said that it was an unscientific agglomeration of opinion. As I was doing it I realized that I could add some spurious but mesmerizing numbers to my analysis by doing a survey. Google's spreadsheet makes the mechanics of conducting a survey really simple, so I couldn't resist.

BlueGreenDeployment

One of the goals that my colleagues and I urge on our clients is that of a completely automated deployment process. Automating your deployment helps reduce the frictions and delays that crop up in between getting the software "done" and getting it to realize its value. Dave Farley and Jez Humble are finishing up a book on this topic - Continuous Delivery. It builds upon many of the ideas that are commonly associated with Continuous Integration, driving more towards this ability to rapidly put software into production and get it doing something. Their section on blue-green deployment caught my eye as one of those techniques that's underused, so I thought I'd give a brief overview of it here.

ConversationalStories

Here's a common misconception about agile methods. It centers on the way user stories are created and flow through the development activity. The misconception is that the product owner (or business analysts) creates user stories and then put them in front of developers to implement. The notion is that this is a flow from product owner to development, with the product owner responsible for determining what needs to be done and the developers how to do it.
