Chainsaw is a GUI log viewer and filter for the Log4J package. It listens for LoggingEvent objects sent using the SocketAppender and displays them in a table. The events can be filtered based on Priority, Thread name, Category name, or Message. It can also load events logged to a file.
FaCiLe is a constraint programming library over integer finite domain written in OCaml. It offers all usual facilities to create and manipulate finite domain variables, arithmetic expressions and constraints (possibly non-linear), built-in global constraints, and search goals. It also allows you to build easily user-defined constraints and goals (including recursive ones), making pervasive use of OCaml higher-order functionals to provide a simple and flexible interface for the user.
BitTorrent is a tool for copying files from one machine to another. FTP punishes sites for being popular. Since all uploading is done from one place, a popular site needs big iron and big bandwidth. With BitTorrent, clients automatically mirror files they download, making the publisher's burden almost nothing.
OnlineCourse is a Zope Product that allows you to implement a web based distance learning application. Main features include an online chat classroom, message board, upload of course materials from MSWord .doc files, log of student participation, and provisions for assignment entry, homework entry, and grading.
GNotary is a set of Python scripts that implement an asynchronous digital notary service. Anybody who needs certification of any digital document creates a message digest (like MD5 or RIPEMD160) of that document and submits it to the GNotary service by email. GNotary signs this email digitally (using GnuPG), retains a copy of the certified and time stamped message, and mails it back to the sender, optionally with the public key attached to allow the sender to verify the signed document. At regular intervals, the GNotary server creates message digests of its own logs and distributes them among other GNotary servers, thus making it virtually impossible to forge the chain of evidence that authenticates a submitted document.
XOTclIDE is an integrated (interactive) development environment for the Tcl and XOTcl language, a highly flexible object-oriented extension of Tcl. It provides a Smalltalk-like programming environment similar to Squick. It allows graphical introspection and editing of a running system (based on Tcl's and XOTcl's introspection facilities). The system state can be saved in the form of Tcl packages. It can optionally use a version control system based on a relational database (MySQL, PostgreSQL, ODBC, or SQLite). All system changes are saved to the database on the fly. It provides browsers for viewing and editing xotcl classes and objects. It also contains syntax highlighting and a static code checker for TCL and xotcl. It contains many developer plugins.
