What is Software to You?
I first experienced software as entertainment (computer games).
Since then software grew into a hobby,
later an education,
then a career,
and then into a business.

As I grow older, I have also started to view software as science
and as art.

That is what this website is about. Software.

Tutorials 
My tutorial site contains 500+ texts organized into structured trails, on Java, web app development and related topics. The number of texts has been growing by about 100 texts per year, and I plan to keep that growth level. The site currently serves about 120.000 unique visitors per month, and this number keeps growing too.
