As Microsoft continues to support and participate in open source communities, the company is again a proud sponsor of the annual O'Reilly Open Source Convention (OSCON), which is being held in San Jose from July 20 to July 24.

In addition to having a booth on the show floor, Tony Hey, the Corporate Vice President for Microsoft External Research, will deliver a keynote address on Thursday July 23, titled "Open Tools and Services on Microsoft Platforms," which will examine the far-reaching changes open research tools and services will have to support every stage of the research process.

Erik Meijer, one of Microsoft's Principal Architects, will also give a keynote talk on Friday July 24 and titled "Fundamentalist Functional Programming."

His talk will argue that fundamentalist functional programming - that is, radically eliminating all side effects from programming languages, including strict evaluation - is what it takes to conquer the concurrency and parallelism dragon.

Following his keynote, Erik is also presenting on using the LiveLabs Reactive Framework to democratize the cloud.

Vijay Rajagopalan, a Principal Architect in Microsoft's Interoperability group, is also giving a talk on Wednesday July 22 in the Product and Services Track, titled "Interoperability - Build Mission Critical Applications in PHP, Ruby, Java and Eclipse Using Microsoft Software & Services."

During his presentation, Vijay will talk about how Microsoft has delivered multiple technologies that focus on interoperability with non-Microsoft and Open Source technologies. He will also show how developers can, today, use Eclipse tools to build Silverlight applications that run on PCs and Macs, as well as how they can develop using combinations of PHP, Java and Ruby in addition to the standard Microsoft languages.

In addition to all the talking, we also expect to do a lot of "showing," and a number of product groups will be represented in the Microsoft booth, including folk from the Education, External Research, Open Source Technology Center, Interoperability and CodePlex parts of the company, all of whom will be giving technical demos and chatting to attendees..

An analyst/partner roundtable discussion is also on the cards, as is a broader interoperability discussion. You won't want to miss any of it.
