16. SEDNTERP 2 Update on

17. 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

18. 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

19. Why use Java script? No recompilation  New Computations  New Tables of values  New User interfaces  New Graphs  E.g. Concentration unit conversion Download: http://bitcwiki.sr.unh.edu/index.php/Downloads
