Anatomy of Linux Kernel Shared Memory
An anonymous reader sends in an IBM DeveloperWorks backgrounder on Kernel Shared Memory in the 2.6.32 Linux kernel. KSM allows the hypervisor to increase the number of concurrent virtual machines by consolidating identical memory pages. The article covers the ideas behind KSM (such as storage de-duplication), its implementation, and how you manage it.
Have you been living in a box?
Linux is to IBM what 'FreeCreditReport.com' is to Experian.
They've been using it for years to hook people into their hardware so they can then switch them up to proprietary software to actually get the job done. They pretend to be wildly open source and all about doing it cheap ... and once you get roped in you find out to actually do what you want, you gotta pay for it.
Unless you were born sometime in this year (like the last 4 months) I find it hard to believe you are unaware of IBMs Linux advocacy ... They seem to do more for Linux than Redhat does, Canonical is the only company I can think off thats more visibly Linux centric than IBM.

"or has linux networking changed sense 2005"
No, Mr. Ballmer - nothing has changed in Linux in years now. It's safe to stick your head back up your arse, and assume that Windows is superior to everything in the world. The schmucks out there still believe it, and sales are stable.
"Windows is like the faint smell of piss in a subway: it's there, and there's nothing you can do about it." - Charlie Br
So if you disagree, why did you go ahead and point out examples for me?
Aside from all the places that memory is shared between processes, theres no sharing between processes ... yea, I totally get you ...
Yes, if you exclude everything else, this is new and exciting.
