The 2010 Eclipse community survey [PDF] has just been released, and again Linux and Ubuntu is showing strong growth on the developer workstations. Some of you may remember my post on this subject last year.
From last year Windows continued its decline, while Linux continued its ascent as a developer platform:

Working from the ODS document that provides additional data, I then dug up the linux OS stats. Ubuntu has grown from 14.4% last year to 18.3% this year, or 56.1% of those running Linux as their development platform.

The growth is less spectacular as a deployment environment (which are always more conservative, no surprise here), with Ubuntu growing from 11.4% to 12.6% of all OS used for deployment, or 28.7% of the linux subset. In the same period, Windows remained stable.

This is good stuff.

For both development and deployment… both Ubuntu and Fedora showed year to year growth according to the survey.
It's unfortunate that CentOS isn't broken out. It's unclear how CentOS installs are handled in that survey. Are they RHEL or are they other? Other surveys like GroundWork's deployment stats show CentOS can be a significant deployment target.
Yes, that's a miss
Good question to ask the Eclipse foundation. From their list of choices, I guess it might have fallen under Linux-Redhat or Linux-Other. Hard to tell.
not just the ratios we need
of course it could be that there's better windows development tools than eclipse so people have been leaving it – you'd have to look at absolute numbers as well as relative quantities
Absolute numbers
Right, but the only absolute numbers we have is the number of respondents. Even if that does not mean much, they are significantly larger than in 2009.
