Microsoft 'Midori' mention makes it into new research presentation

Summary: It's been a while since I've found any new information about Microsoft's Midori operating system skunkworks project. But recently, a new Midori nugget surfaced.


As Microsoft codename watchers know, one of the codenames the Softies have tried their best to keep under wraps is "Midori." But last month, one Microsoft researcher slipped an interesting Midori reference into a presentation that makes it seem that Midori is still alive and well.

First, a quick codename refresher: Midori is a new operating system being developed by a team inside Microsoft that isn’t based on the current Windows kernel. Headed by Senior Vice President of Technical Strategy Eric Rudder, Midori is/was to be a distributed, concurrent operating system, according to various tips. Currently, the product and associated deliverables (a related programming language/framework, etc.) are still in technical incubation, I believe.

Another couple of Microsoft codenames that figure into this picture include Drawbridge and Singularity. “Drawbridge” is a Microsoft Research project developed by some of the same folks who helped create the Singularity microkernel operating system inside Microsoft Research. Drawbridge is a new adaptation of the “library OS” concept. It is a form of virtualization that seeks to replace the need for a virtual machine  to run software across disparate platforms. (Thanks to Channel 9's Charles Torre for the concise explanation.)

During a March 9 presentation, Galen Hunt, principal researcher in Microsoft Research's operating-system group, made a brief presentation on Drawbridge (as noted by "felix9" over in the MIcrosoft Channel 9 Coffeehouse chatroom).

We know from previous published articles that Microsoft has managed to test Drawbridge on Windows 7, Windows Server 2008 R2, Windows 7 MinWin, a pre-release version of Windows 8. But now we know that the researchers on Drawbridge also have managed to host it on top of the Xbox platform, Windows Compact Embedded, Barrelfish (another Microsoft Research operating system project) and ... Midori.

Here's the rather grainy slide from a video of Hunt's presentation which includes a reference to Midori:

Hunt said during his presentation that the Drawbridge team has done different library OS implementations across different hosts, and some of these "look very much like Windows as a host and some don't."

As I often note when writing about Microsoft Research projects and incubations, there is no guarantee that any of the technologies discussed and demonstrated here are going to become commercial Microsoft products or parts of products. However, I disagree with some Softies and Microsoft watchers who say that delving into these kinds of Microsoft technologies is nothing but an exercise in Kremlinology. Increasingly, many of these kinds of projects inside the Soft end up influencing heavily technologies that will ship from the company in the next five- to ten years.

  • more vaporware...

    the only stuff M$ is prolific at!

    • Learn the definition of vaporware

      if they do not announce anything then it is NOT vaporware. This is a research project currently and there is no plans on releasing it (at least none that Microsoft has discussed) therefore it is NOT vaporware.
  • KIN?

    The KIN was running on Win7 MinWin?
    • Danger

      I thought Kin was a Danger legacy.
    • Good catch!

      That's very interesting.
  • I thought Midori was a web browser

    ...which I use on Bodhi Linux.
  • I'm glad Midori is not dead

    I've been praying for the death of COM for a long time (although Win8 is keeping it even more alive than ever).

    Midori sounds really interesting, the managed code aspect and the distributed stuff sound very cool.

    Come on MSFT, see it through to the end! Love to see this eventually replace windows...
  • Leave it on the drawing board

    Having a Microsoft hosted OS will take up back 30 years, I want the OS on my hard disk where I control what it does.

    Not to mention of course it'll be a boon for authoritarian reigmes as MS will simply roll over and give them any info they want in exchange for a juicy contract
