Last week Microsoft announced a new platform called Live Mesh that is a software-plus-service offering to enable PCs and other devices to interact with one another over the Internet. Currently access to the preview of this service is available on an invitation only basis (and only in the US for now). I haven’t had a chance to play with it yet myself, but I do see more and more services like these taking hold. Things like Amazon’s S3 and data services, Google’s Gears, Microsoft PopFly and even Facebook’s API make it easier and easier to develop applications that live “in the cloud” and are easily “mashed up” with other, similarly deployed applications. It wouldn’t surprise me if this year’s PDC (in October) features many such in-the-cloud services from Microsoft, with things like online application hosting, database, file storage, and of course interoperability being the centerpieces of such offerings.

Warning: Use of CodeSmith may cause unforeseen productivity

April 2008 -- Business managers rioted outside the offices of CodeSmith Tools in Dallas, TX today complaining of developers 'going home early' and 'getting projects done too soon'. "CodeSmith does their work for them, they just write a template and hit 'run'," said one pointed headed manager, "it's just not fair! What with CLSA, LINQ, .netTiers, and more frameworks all just built in? With all of this productivity they might not need us anymore."
