My first mainframe job—
My first job was at Prudential Insurance Company. I was a rookie system programmer. Mainframes were the only game in town, and I worked on IBM’s S/370 systems. I started to love mainframe computing–Mondays felt the same as Fridays!

Over the years my career path led me to specialize in mainframe security, a role that I still practice.

My favorite mainframe memories—
I have always admired the mainframe’s stability and resilience in the face of stiff competition from newer platforms. As the technology changes, so does the mainframe.

This Darwinian principle of adaption has allowed the mainframe to retain its place in the present day networked business environment.

On a lighter note, I can vividly recall an incident from my first job. A not-too-happy employee decided to print his resume on the company’s printer. The printing in those days was done in a central location, in the computer room. Through a slight JCL error, instead of one copy the employee had requested one hundred copies of his resume to be printed! This large output drew the attention of the computer operators, who reported the incident. Eventually the whole department came to know, causing much grief and embarrassment to the guilty employee.
