Not the Astronaut!!
I have been working with computers since the 1980's. My first computer a TI 99 was bought with my paper route money. Now some 40 years later, I have my own HP Proliant ML 350, with a bunch of Virtual Machines I use for development, mostly Linux.
Some time ago I wrote a paper on living with 400 IOs per second which took a look at disc IO.
Read The PaperIn the practical world of computing, it is rather uncommon that a program once it performs correctly and satisfactorily, remains unchanged forever.
