IBM System/390: The Linux Dream Machine

Running 41,400 Linux virtual machine O/S on a single IBM S/390 mainframe:

[...] This gets better: nobody ever said you could only run one VM Linux system at a time. In fact, you can run multiples of Linux just as you run multiples of CMS. Just imagine one physical computer with several thousand copies of Linux running on it simultaneously, and each of these supporting multiple user connections. Fantasy? I have heard from one system administrator, David Boyes at Dimension Enterprises, who decided to push the envelope on this. His test system finally ran out of resources at 41,400 Linux images. That's not a typo--there were forty-one thousand copies of Linux running on one logical partition of one mainframe, under VM. [...]

Adam Thornton of Flathead Software fired up a 390 emulator called "Hercules" (originally designed to emulate 370-series mainframes on Intel hardware) underneath Linux underneath VM. Then he ran another Linux boot underneath that. The hack value of this is just, well, way cool.

Banco Mercantil Moves to Linux on IBM Mainframe

Venezuelan Bank is First Financial Institution with SuSE Linux

IBM and Banco Mercantil today announced that Banco Mercantil is the first Latin American company -- and among the first financial institutions anywhere -- to implement Linux for the enterprise.

In the first phase of the project, Banco Mercantil has replaced 30 existing NT servers with a single IBM mainframe. Later, applications currently running on Sun and HP servers will be moved to the new Linux platform. In addition, the bank is using Linux mainframe Web applications to enable customers to check bank account information via the Internet. The mainframe's two cryptographic co-processors provide the high level of security necessary for sensitive financial data.  [...]

Free Software Leaders Stand Together

A response to Microsoft's claim that Open Source software is unworkable:

[...] With very little funding, the GNU/Linux system has become a significant player in many major markets, from Internet servers to embedded devices. Our GUI desktop projects have astounded the software industry by going from zero to being comparable with or superior to others in only 4 years. Workstation manufacturers like Sun and HP have selected our desktops to replace their own consortium projects, because our work was better. An entire industry has been built around Free Software, and is growing rapidly despite an unfavorable market. The success of software companies like Red Hat, and the benefits to vendors such as Dell and IBM, demonstrate that Free Software is not at all incompatible with business. [...]
