Microsoft — or at least part of Microsoft — continues its quest to persuade open-source developers that Windows should be on their short-list of platforms. You know, right up there with Linux.
Sam Ramji, the Microsoft guy whose job it is to mend fences and foster collaboration with open-source ISVs and other partners points to progress. 
Exhibit A: Ramji — his formal title is director of platform technology strategy — will keynote at this spring’s EclipseCon conference. Not traditionally a big venue for Microsoft execs.
Exhibit B: Nearly a third (30 percent) of SugarCRM’s business is now on Windows, he says. SugarCRM is the open-source CRM pioneer. Two years ago Microsoft and SugarCRM inked a technical collaboration pact.
Exhibit C: Of the 140,000-some-odd applications on the Sourceforge repository some 77,000 now run on Windows, Ramji says. Admittedly, a large number of that 140,000 are probably dead apps, but why quibble?
