Years in IT—
My first mainframe job—
It involved migrating from MVS to OS/390 as part the business’s effort to become Y2K compliant.
My favorite mainframe memory—
I have been involved in porting GPL source applications from IA Linux to Linux on System z. For example, I've ported QEMU to Linux on System z, and operated the IA-based OS. In the Japanese bank, it performed grandly because of the design of the IBM mainframe’s system infrastructure.
