XOTcl provides a highly flexible, reflective, component-based object oriented environment that integrates language support for high level object oriented concepts (which are not found in other languages) with reasonable performance. XOTcl is an extension of TCL and was derived from the impressive OTcl language developed by D. Wetherall and C. Lindblad at MIT in 1995 and extended in various ways. XOTcl's language constructs explicitly aim at the complexity in a component gluing layer that is not solved by traditional object orientation in the style of C++ or Java.
Bulk Mailer helps speed the delivery of an email message to many recipients using Sendmail. It's best used in parallel with a mailing list manager such as Majordomo. For input, it takes a file of recipient addresses (one address per line) and a message (with headers already attached) to be sent to the recipients. It sorts the recipient list by reversed domain (so similar ones sort together), splits up the recipients into several groups containing no more than N domains each, creates an SMTP envelope for each group of recipients, and feeds each envelope to sendmail.
NoSQL is a fast, portable, relational database management system without arbitrary limits. It runs under, and interacts with, the UNIX operating system. It uses the Operator/Stream DBMS paradigm. There are a number of "operators" that each perform a unique function on the data. The "stream" is suplied by the UNIX input/output redirection mechanism. Therefore each operator processes some data and then passes it along to the next operator via the UNIX pipe function. This is very efficient as UNIX pipes are implemented in memory. NoSQL is compliant with the relational model.
The QNX Message emulation library provides an emulation of the QNX4 message passing functionality for use with Linux. The package contains an emulation demon that provides the services used by the programs. The applications are linked with a special library that communicates with the demon. The readme file contains a complete list of supported functions.
