The Rich Engineering Heritage Behind Dependency Injection

Andrew McVeigh takes us on a tour of the rich heritage behind dependency injection, what it represents, and tells us why its here to stay.

Java, the OLPC, and community responsibility

The "One Laptop Per Child" project has a great device ready to ship, but there's no Java on there. Let's think about working together to put Java on OLPC!

Paid for OSGi support

Moving towards OSGi is a great idea (and Neil's been busy explaining how recently ) and a lot of key early adopters are already there (Eclipse, WebSphere, Spring ...). But what happens when a commercial organisation wants to go there? You can't call up a regular training organisation -- who likely as not have not heard of OSGi -- in order to start architecting OSGi solutions. Of course, you can come and listen to it in a couple of weeks time at JSig if you're lucky enough to be in (snowy) London; but sometimes you'd need to fall back on experienced resources.

Enter OSGi4Enterprise , an initiative offering support, training and consultancy on the OSGi platform. This has been set up by two existing consumers of OSGi systems; Paremus (whom we've mentioned before on here, with their open-source Newton distrubted component model along with the Infiniflow commercial offering) and Gatespace Telematics (who provide the Knopflerfish OSGi engine and its paid-for sibling Knopflerfish Pro ).

I recall being ahead of the curve before J2EE made it big, and seeing the companies spring up to serve needs of other consumers. Of course, as it grew, the competition also grew; but you could tell that the computing world was going to be changed by the oncoming wave. I think that this is exactly the same situation that we're in at the moment; OSGi is in the process of taking off, and if you look back in a few years time, OSGi will be commonplace under the hood of both GUI and server-side systems.

Well, OK, so I live in Milton Keynes. But I've not made it into London since it started snowing.

Here's a couple of people rolling a giant hailstone out of the way:

No, it's a snowball really

Actually it's more of a surprise to me, since I live in Germany Munich and around this time of year we usually have masses of snow but this year no snow, tempratures around 4 to 12° Celcius and the weather is all haywire.
And last time I was to London in winter it was the other way around...
