Duncan Cragg...

...has spent the last two decades finding ways to explain that programming needn't be limited to:
Threads, Message Queues, Client-Server, CORBA, Web Services, SOAs, Agents, Synchronous Architectures and Imperative Programming

...worked for ThoughtWorks UK from April 2002 to July 2007 and now works for the Financial Times as a Web Application Architect

...is writing a book called 'The Reality Web', about our digital future

...went to both UCL and Imperial College of the University of London (in the Eighties); specialising in Logic during his MSc.

...got hooked on the idea of 'microcomputers' nearly three decades ago, then designed and built one using the 1802 chip, 512 bytes of CMOS RAM, eight switches and eight LEDs

...supports the Open Rights Group, Open Source and Freedom generally

...wonders when his LinkedIn Account will be useful

...loves Django so much he built this blog on it

...has a phone-cam, and used it on himself once, just before his weekly shave:

The Rebels vs. the Empire...

The enemy keeps changing. Bloated 'enterprise' technology has constantly changed form to try and outwit us. First DCE, then CORBA, next J2EE and now:

Google Micro Conference October 5, 2007 11:22 Last night's Google London Open Source Jam (also here) was on the subject of the 'Web' (didn't they invent that? Oh no, that was Microsoft). This event has been getting better and better each time I've attended. There were some very interesting lightning talks held together with a tight structure and plenty of chance to chat, drink cold Leffe and eat cold pizza. And nick [transatlantic translation: 'steal'] the Green & Black's chocolate. An ideal Micro Conference... ...

Which means it is in competition with Java and .Net, and with SOA, for both local and widely distributed applications. If the Web is going to be a platform, the skills you need to learn to program it are the core Web 2.0 technologies such as Ajax, JSON, Atom, Microformats and OpenID. And Ruby. This language, that's capturing the hearts of many Web 2.0 programmers, is ideal for easing the transition from the Java and .Net platforms to the Web platform, as I will show. Even if you're part of a big company that is generally immune to the latest trends, the marriage of Ruby and the Web-as-platform may be something to prepare for. It could even displace your SOA agenda... ...

Although eBay have what they call a 'REST' interface, it is, in fact, a STREST interface, and only works for a few of the many function calls that they make available via SOAP (GetSearchResults, GetItem, GetCategoryListings, etc). In this dialogue series, I argue the case for eBay to adopt a truly REST approach to their integration API. Part 5: The Distributed Observer Pattern ...

Both are approaches I give, ahem, special mention to on all my pages at the bottom of the left-hand column. So it was with some apprehension that I opened up this (PDF) slide pack from Dan Pritchett and Randy Shoup of eBay, presented at SD Forum 2006 recently. I was expecting my prejudices around the issues and techniques of scaling web sites to be challenged, at least. ...

The Web's Declarative nature needn't be broken just because you want two-way dynamic data instead of one-way documents on your site. Instead, write Declaratively to generic Javascripts, plugins and browser features such as Hijax, hInclude, XForms, SVG, XBL, etc. ...

The How has dominated the field - perhaps 80% of programming is done in the traditional Imperative style, where we tell the computer How to do a task in explicit steps. I'd like to show in this blog how Declarative Architectures and technologies are not just an interesting sideshow to the main Imperative attraction, but a complete and powerful programming alternative in their own right - indeed, one which has already dominated certain fields. Imagine being able to simply express What we want the computer to do - to give it constraints and rules - then let it work out for itself How to achieve our goals. I believe that saying What, not How, will become the dominant paradigm in programming. ...
