Our quiz today focuses on Linux, which Linus Torvalds originally created in the early 90s for x86 desktop hardware—about as far from a mainframe as you can get. But its life on mainframes has proved remarkably powerful. Through the mid-to-late 90s, Linux gradually gained serious traction, powered by the internet boom, professional distributions like Red Hat, and growing vendor support from Oracle and IBM.

In 2000, when IBM rebranded its mainframe line as z/Series, it made a landmark decision to port Linux to it, bringing a once scrappy open-source kernel to the most buttoned-up hardware in existence. The unlikely pairing has worked remarkably well, letting enterprises consolidate massive Linux workloads onto single mainframes, and helping give a decades-old platform a truly vital second act.

1. In what year did Linus Torvalds first release the Linux kernel publicly?

 
 
 
 

2. What was the original intent behind Linux when Torvalds began the project?

 
 
 
 

3. Which UNIX-like system inspired Torvalds during Linux’s early development?

 
 
 
 

4. IBM announced major support for Linux in 2000. What was a key strategic goal of that move?

 
 
 
 

5. What do the “Halloween Documents” refer to?

 
 
 
 

6. What role does Linux typically play alongside z/OS in modern environments?

 
 
 
 

7. Which concept allows Linux workloads on a mainframe to scale into the thousands of isolated environments?

 
 
 
 

8. Which animal is the Linux mascot, “Tux?”

 
 
 
 

9. What is a common reason organizations move distributed Linux workloads onto a mainframe?

 
 
 
 

10. What distinguishes Linux on a mainframe from Linux on commodity servers?
