libtai is a library for storing and manipulating dates and times. It supports two time scales: (1) TAI64, covering a few hundred billion years with 1-second precision; (2) TAI64NA, covering the same period with 1-attosecond precision. Both scales are defined in terms of TAI, the current international real time standard.
JORA will simplify your development of database applications, establishing implicit mapping between relational database tables and Java classes. JORA uses JDBC for database connection, so it can be used with any database supporting JDBC or ODBC. JORA also allows you to use object-oriented features, such as polymorphism and complex objects, in your database applications.
tkbiff allows arbitrary commands to be executed upon mail reception. If you like programs such as xbiff and xbiff++ but wish they were more flexible, then you'll like tkbiff. Unlike other biffs, tkbiff is fully customizable. tkbiff also doesn't waste your valuable screen space with icons; instead, it shows you the mail itself. It supports UNIX, Mac, and Windows, IMAP, POP, and UNIX-style mail files, and SSL and APOP.
