Microsoft/Linux milestones

From famous Halloween memos to Microsoft submitting source code for Linux kernel, much has changed

Microsoft Monday made an historic move by submitting device drivers to the Linux kernel under a GPLv2 license. Microsoft has had a checkered past with both Linux and its open source GPL licensing structure, so the move was a jaw dropper. Here is a look at some of the milestones since Microsoft internal memos leaked in 1998 that attacked the open source Linux operating system as it began to pick up steam as an alternative to Windows.
