In February 2000, Scott Courtney's article "S/390: The Linux Dream Machine" was published on LinuxPlanet.com, and raised the level of awareness of mainframe Linux in the general Open Source community. This presentation is a retrospective on how, largely by accident and coincidence, that article came to be, and how mainframe Linux has changed since those early days. PDF

The VM operating system allows many hundreds, or even thousands, of Linux images to run simultaneously in their own virtual machines on a single IBM S/390 or zSeries mainframe. In this presentation, created by David Boyes and presented at SHARE 98 by Scott Courtney, we examine what happens when the number of running Linux images is pushed to its extreme limits. A history of the widely-known "Test Plan Charlie" and lesser-known "Test Plan Omega" demonstrations is included in the presentation. PDF

Linux and other Open Source software offers both technical and business benefits. To an IT executive, the technical merits of Linux may seem to be little more than geeks wanting to show off their "coolness." This presentation by Scott Courtney attempts to bridge the gap, explaining what it is about Linux that has the geeks raving, and how the "coolness" of Linux can actually translate to business advantage.
