The Beginning
- HTL 1 Bau und Design
- same stuff over and over again
- coded useful scripts
- published them (http://doebi.at/rechner/)
- too specific
The Idea
"an online easy to use general purpose
statics calculation app"
Make it better
- incompatible with newer OSs
- confusing UI
- expensive
The Concept
-
web app in your browser
-
no dependencies
-
works on any OS
-
server as brain and backup
-
anywhere with any device
