SEDNTERP 2Update on

Sednterp 2

Based on Sednterp 1 Thanks to John Philo

Same calculations Same logic Imports existing

Sednterp 1 data Multiple versions

Windows XP 7 Mac OSs Linux Web

What’s new in Sednterp 2

Uses “daemon” model SQLite DB Javascript computations in modules Rendering engines for desktop & web Public web version in May

David Hayes’ help file now is a Wiki PDF version available for “unconnected” computers

Daemon has TCP/IP socket Allows external programs to use Sednterp 2 XML commands documented CFA software will use this

Why use Java script?

No recompilation New Computations New Tables of values New User interfaces New Graphs

E.g. Concentration unit conversion
