So Bart De Smet is a rock star in Belgium

At least in TechDays Belgium 2013 .

Because, there is a Bart De Smet Unplugged session, which usually for stars, right ?

The other two sessions are also interesting: Behind the scenes of (as many) C# language features and Introducing TypeScript, apparently Bart knows EVERYTHING, curious what he is working on now, according to LinkedIn:

October 2012 – Present (6 months) Bellevue, WA

Yet unannounced projects.

March 2012 – September 2012 (7 months)Redmond, WA

Working on Reactive Extensions (Rx) v2 and various LINQ-related projects.

Now we just need to videos to be uploaded.

@felix9:  Thanks for the link ... was that just posted?  Pretty late, no?

@Richard.Hein: Not sure about the exact time it posted, but I just noticed them today.

And I don't think its so late, I guess they are produced and uploaded from Europe, encoding and distributing also takes time.

Interestingly Bart said in the video above:

Currently I'm working in the Online Services Division, but my big passions are actually virtual machines and languages, I leave it to your imagination what I'm working on in Online Services.

My guess is something similiar to Tangram:

The technology stack includes a declarative side-effect free runtime, an expression language, a graph-based document architecture, and an authoring environment. The technology is shipping as part of Microsoft Powerview, and has been live in Bing since 2009.

Just a thought , of course there are many other stuff like Cosmos/Scope, or something completely new.

@felix9: Well he did say that writing De Bruijn indices has become a way of life ... what can that be used for?  I thought something like Wolfram Alpha - expression rewriters, automated formula manipulation, theorem provers etc....http://en.wikipedia.org/wiki/De_Bruijn_index.  That would fall into the Tangram space, as well.  However, Bart wouldn't bite and give me more hints when I asked.
