It was 2002 or so. I was a student in middle school, and in our school we have additional hours for maths, physics and informatics. So, on informatic lessons we wrote programs in QBasic45. In maths classes we have tonn of homework, and someday it was solving about hundred of quadratic equations. So, I got my father's book about programmng in Delphi 5, and wrote programm for solving this equations. I have Internet connection back there, but it was slow as Dial-up could be.... 28800 or 33600, so, it could be hour or two to download such programm... And not only 2 hours of time, but I remember it costs about $2/hour and for 12-years old boy in developing country it was not the smallest money...
