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
