Linux, politics, and other interesting things
There is currently a lot of speculation about the future of Windows following the massive failure of Vista in the market.
One theory that is being discussed is that Microsoft will cease kernel development and adopt a Unix kernel in the same way that Apple adopted a BSD based kernel.
I predict that MS in it’s current incarnation (*) will never do that. Having an OS kernel that enables easy porting of code to/from other platforms is entirely against their business model which relies on incompatibility to lock customers in. Whatever kernel MS use, it has to be incompatible in some ways with everything else. One easy way of achieving this would be to have a shared object (DLL) interface published and have the interface between the libc and other libraries and the kernel be undocumented and ever-changing (simply renumbering the system calls on every minor version increment would be a good start). The DLL interface could then have the complex APIs that MS loves to force on their victims (see Stewart Smith’s post about getting a file size in Windows for an example of the horror ).
The advantage of this approach would be that MS could cease developing an OS kernel (something that they were never much good at) and concentrate on owning the proprietary DLLs. There would be nothing stopping them from using a Linux kernel for this, as long as they release all source to the kernel they use (including the patch to renumber the system calls) they would be within the terms of the GPL.
My specific prediction is that some time between Jan 2011 and Dec 2016 Microsoft will release systems with the majority of the kernel code coming from BSD or Linux as their primary desktop and server operating systems.
Could people who disagree please make specific predictions for the future (including dates and actions) so that we can determine who was most accurate.
(*) For future incarnations of Microsoft after chapter 11 or being split in the way that AT&T was there seems no possibility to predict their actions.
