Yesterday Julie Bort wrote in the NetworkWorld site an interesting post called “Cisco doesn’t contribute nearly enough to open source”, where she contends that “”[despite its] .. proclaims it responsible for a half percent of the contributions to the Linux kernel (0.5%). In reality, Cisco has been a near non-entity as an open source contributor”. Of course the author is right in its claims – the amount of contributed code to the Linux kernel is substantial but very “vertical”, and specific to the needs of Cisco as a Linux adopter.
