Windows CE 6 Arrives Complete with Kernel Source 169

An anonymous reader writes "Microsoft has launched the sixth edition of their embedded OS Windows CE and this time has included the full source. From the article: 'Developers can now access shared source code for the Windows CE kernel -- as well as certain device drivers and application-level components -- directly from within the Windows Embedded CE 6.0 distribution package. To do this, they click on a function in the IDE that installs the shared source, and indicate their acceptance of the associated shared source license.'"

For those you don't know, 90% percent of Windows CE code (I think its everything expect Windows Media Player and Pocket Internet Explorer) and only charges small royalities (I think it's $6 dollars) per device, and you can do things like port it to a new platform if you wish (assuming you had the required compiler).

I also wonder if there is enough code to flash CE 6 onto a CE 5 device (I have a T-Mobile MDA with Windows CE 5, I wonder if I can simply drop the new kernel in there).

      Typically Micosoft's shared source means that they can share the source code with you, but you can't modify it and redistribute or share it with anyone else. Most of the time it won't compile properly or will fail to operate after compilation due to not knowing what compiler flags to set and / or not having a compiler that will understand and handle any non-standard syntax that's been "injected" into the language.

    At this point in time there have been a number of projects from microsoft that have released their sources under some license or another. Some of them have been true open source licenses, and remarkably those have been hosted on sourceforge along with all the other oss stuff. I'll list the few I know about here and maybe others can mention a few.

    A toolset for building installer packages on windows. Supposedly one of the better ones.
    license: cpl []

    An extension to the ATL. Probably the best toolkit for developing win32 guis in c++ (lightweight and powerful). It's hampered by the fact that documentation for it is scatered around the net (mostly on the code project) and so mostly people usually end up learning about it by reading through the largely uncommented source.
    license: cpl (alternately available under a different, maybe equiavent license if downloaded from microsofts site) []

    A cross platform implementation of the .NET runtime developed by microsoft. Runs on windows and BSD I believe, and has been ported to linux by third parties. I don't believe it includes the .NET framework, and is more designed as a reference implementation of "how to get .NET working on other platforms" than anything else.
    License: shared source r/ []

    Windows CE:
    Mentioned in article. I think they release it under this license for custimization and debuggin purposes.
    License: shared source censing/WindowsCE.mspx []

    So far microsoft seems to use the shared source license and the CPL license.

    The shared source license is relatively restrictive, and generally leaves microsoft with most of the power over issues of reditribution and use of source. Shared source seems to be largely used to distribute code for educational, debugging, and customization uses.

    The CPL is a full blown open source/free software license that was actually written by IBM and I believe is the license that eclipse is distributed under (only under a different name). Community projects like Wix and WTL are being handled under this license.

    My impression from talking to microsoft guys and from working there briefly is that the antipathy felt towards linux and open source is not particularly pervasive in the company. I've met a few people who had negative misconceptions about open source, but whatever the average slashdotter might think microsoft tends to hire smart people who are aware of industry trends and best practices including oss.

    From TFA: The opening up of Windows CE's kernel source code is likely to make Windows CE more attractive as an alternative to Linux in many embedded applications and devices that require substantial customization of the OS, or where source code availability has been mandated by the development team. Additionally, Microsoft touts the terms of its BSD-like shared source license as being preferred by many device and equipment manufacturers that don't want to be compelled to make their OS customizations public and available to their competitors.

    On the other hand, following a long to an older article, I read: In terms of impact to Microsoft's Windows CE Shared Source and Shared Platforms initiatives, Windows Embedded product manager Nic Sagez told that these programs are not migrating to the new licenses any time soon. However, Sagez did not rule out the possibility of a longer term change, based on customer feedback and market requirements.

    Back to TFA: For the first time, Microsoft is making 100 percent of the source code of the Windows CE kernel available as part of the Windows Embedded CE 6.0 operating system package, to everyone who gets the OS package.... but nowhere does it explain just which of the many licenses described in the earlier article [] is actually being used. It seems disingenuous to "touts the terms of its BSD-like shared source license" if the license it's using isn't BSD-like... and, clearly, it's not:

    Developers and companies are permitted to use the evaluation version to begin their projects, and need not pay anything to Microsoft until the time limit expires, after which a non-evaluation version is available for $995 -- or when they begin to ship product that requires run-time royalties, Microsoft says.

    Run-time royalties? BSD-like license? Please!
    • Except for the restrictions regarding legal action, the Ms-PL (Permissive License) [] seems sort of BSDL []-like. You're allowed to edit the source, you're allowed to redistribute it, and you're even allowed to close it (redistribute it sans source). You're not allowed to take credit for the original version and the software is licensed "as-is".

      IANAL but I think the main difference between the Ms-PL and the BSDL is the Ms-PL term 3B:

      If you bring a patent claim against any contributor over patents that you claim

        The point isn't "does MS have a BSD-like license".

        The point is "if they're going to tout their BSD-like license when talking about Windows CE, they bloody well better be using that license for Windows CE".

        Because they're obviously not. Which one are they using? Do you know?
  • This could be a big boon for development of Linux ports to these handheld platforms. The hassles of figuring out how to access certan bits of hardware, could be greatly mitigated through the information in these sources. Of course, great care would have to be taken to avoid contamination and legal issues, but I think it's manageable. I'm a bit concerned that it talks about the kernel and "certain device drivers," though.

    I worked on products using CE 4.2 and 5.0, and we had the source then. Most of it's there, just not some deep kernel internals (like the scheduler). The SS license is a bit restrictive, but hey: whatyagonnado.

    I think they're lowering the cost for everyone. It turns out that most companies that are making a CE product want the source. MS didn't charge for it (well, the CE licenses were pretty expensive to begin with), and it was just costing everybody lawyer-hours.

  • Microsoft are merely following a bandwagon. They won't jump on it, however, until they can be sure of overpowering the driver.

    Back in the 19th century there was much heated debate over whether AC or DC would be better for power distribution. DC had all the big money behind it, but AC had the Laws of Nature behind it. I don't think it's an exaggeration to say that most of what we know today about electronics, would never have been discovered if we were still trying to distribute DC power.

  • So is this the beginning of an open-source Microsoft operating system kernel, atop which a new (.NET powered, perhaps?) Window manager will run? Did Wired have it right all along [] -- except the core will be OpenWinCE instead of Linux?

    Hey -- if Apple fanatics are right, then MS will do something to further imitate Mac OS X, and OpenWinCE under Avalon 2.0 (et al) and dropping all backward compatibility makes more sense than Torvalds taking over the kernel team in Redmond.
