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...   ...

How Ruby can enable the Web 2.0 Platform
June 26, 2007 15:17

Web 2.0's definition includes seeing the Web as an application platform. 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...   ...

Web 2.0 and our Digital Rights
June 23, 2006 17:58

Open Data .. has .. recently .. been.. all .. over .. the .. blog .. o .. sphere!

Openness is a classic Us-and-Them issue. Big, nasty Apple/MySpace/Flickr is trying to control what little me/SingleStatus/Zoomr can do with my/our own stuff.

Open Data vs. Closed; Open Source vs. Proprietary; P2P vs. DRM; privacy vs. surveillance. The battles between the freedom of the pioneer, the individual and the minority against the rules and stability of the establishment and the majority form the endless shape of human history.

Us beating Them is Hollywood's favourite subject on-screen - and ironically Them fighting Us Hollywood's favourite battle off-screen.

As an Us-and-Them issue, with Us less powerful than Them, it's also tempting to give up and to follow the crowd - to do what we're told, to not ask for or sieze the privacy and open data we feel entitled to.

However, at XTech 2006 recently, there was a set of talks on the subject with a more positive approach.   ...

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.   ...
