I have been playing around with computers for the last 25 years. That makes a quarter of century (sounds ancient, uh?), and it accounts for 85% of my life.
At age 6, when kids in my class were staring grasping additions with numbers 1 to 20, I typed on my dad's VIC20

print 10*10

and learn about multiplications.

A couple of years later, I wrote a small program to keep track of score in pocket billiard games (just a fancy version of Hello World, taking some input and doing some calculations). Since then, I managed to learn something more and I even got a degree in Computer Science.
