alphadogg writes "For the first time ever, Microsoft can be counted as a key contributor to Linux. The company, which once portrayed the open-source OS kernel as a form of cancer, has been ranked 17th on a tally of the largest code contributors to Linux. The Linux Foundation's Linux Development Report, released Tuesday, summarizes who has contributed to the Linux kernel, from versions 2.6.36 to 3.2. The 10 largest contributors listed in the report are familiar names: Red Hat, Intel, Novell, IBM, Texas Instruments, Broadcom, Nokia, Samsung, Oracle and Google. But the appearance of Microsoft is a new one for the list, compiled annually."
