It is interesting to compare relative increments to learn more about how changed the attitude of the usual suspects to Linux and how newcomers are doing.
“None” developers - i.e. developers who are known to be doing this work on their own, with no financial contribution happening from any company- are little considered by some commenters, but they contributed 34% more this year (passing from 26644 changes to 35663).
Red Hat and HP contributed 30% more, both IBM’s and Novell’s increments in contribution are below the 20% (respectively 17% and 19%), while Oracle and Google are around +24%.
Intel and Fujitsu are over the 40 per cent threshold, but also Marvell and academia contributions (kudos!) grew at the same rate. AMD is about to double its contributions (+96%), and Nokia with an oustanding +125% is leading the group of the non-usual suspects.
The Linux Foundation is loosing ground, with a tiny +6%, though.
