Web Objects Ask, They Never Tell | The REST Dialogues
August 13, 2009 11:43

In an exclusive nine-part dialogue with an imaginary eBay Architect, we present an accessible discussion of the REST vs. SOA issue.

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.

In this dialogue series, I argue the case for eBay to adopt a truly REST approach to their integration API.

The Mobile 2.0 Killer App is the App Killer
December 19, 2008 17:05

Mobiles are unique - if you want to miss out on the opportunity they represent, you could choose to see them as just slow computers with tiny interfaces and dodgy Internet connections. Then try to squeeze in your traditional applications; try squeezing the office desktop metaphor with its sedentary documents into a device the size of a mouse!

Alternatively, see them as the most personal, social and dynamic of devices that are becoming connected to the Internet. Now a multi-billion-scale global opportunity opens up to you. That's customers and dollars! In trying to grasp this, some are calling it 'Mobile 2.0', by analogy with its sibling, Web 2.0.

In that light, the Killer App for Mobile 2.0 is the sharer, masher and updater of People, Things, Times and Places... The key to getting Mobile 2.0 right is for it to merge seamlessly into our lives. That means the handling of dynamic and shared data becomes the top priority, even above the handling of applications.

This article describes a Mobile 2.0 platform that makes people and their stuff first class - not applications.   ...

 
The Universe Web
July 18, 2008 19:49

Since the announcement by IBM and Linden Lab that OpenSim can talk to Second Life, I've been thinking again about RESTful Virtual Reality.

I'm not the first, of course. Others have been motivated by the same goal: To bring the Web's scalability, linkability and interoperability into Virtual World platforms.

Ultimately, how to use the same techniques as the Web to link Virtual Worlds together into a single, massive 'Virtual Universe'.

Here's how I would architect the Universe Web...   ...

 
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...   ...

 
Inter-Enterprise REST Integration | The REST Dialogues

In an exclusive nine-part dialogue with an imaginary eBay Architect, we present an accessible discussion of the REST vs. SOA issue.

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).

The "Imperative to Declarative Inversion": Open Data is OK!
May 11, 2006 21:36

There is something about the Internet that nurtures open data, and something about computers that nurtures closed. It is often necessary, but often painful, to make the jump from local, closed data to global, open data.   ...

 
Welcome to 'What Not How'
March 22, 2006 17:00

Declarative Architectures focus on the What, not the How, of programming. 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.   ...
