BlueJ is an interactive Java development environment. It provides a unique user interface that presents a graphical display of the application classes and their relationships, and it lets users interactively create objects of any class. Once objects have been created, users can interact with them directly. This interaction mechanism allows for much greater testing and experimentation than in conventional environments. BlueJ is suited for teaching and learning OO and Java.
Boxes is a text filter that can draw any kind of box around its input text. Box design choices range from simple boxes to complex ASCII art. A box can also be removed and repaired, even if it has been badly damaged by editing of the text inside. Since the generated boxes may be open on any side, the program can also be used to create regional comments in any programming language. New box designs of all sorts can easily be added and shared by appending to a free format configuration file. In addition to being a command line tool, Boxes integrates well with any text editor that supports filters.
chrony is a client and server for the Network Time Protocol (NTP). This program keeps your computer's clock accurate. It was specially designed to support systems with intermittent Internet connections, but it also works well in permanently connected environments. It can also use hardware reference clocks, the system real-time clock, or manual input as time references.

Weasel Reader is an e-text reader for Palm OS. It is geared towards reading Project Gutenberg e-texts, but will work on any ASCII file. It uses zlib for compression, resulting in good file sizes, an important consideration for Palms. Weasel reads both zTXT (its own format) and PalmDoc files. It includes features such as bookmarks, annotations, categorization, searching, beaming, VFS access, and many display options. Also included is makeztxt, a command line program to generate zTXT databases. makeztxt supports regular expressions to automatically generate a list of bookmarks. Java and Perl/PHP versions of makeztxt are also available.
HickUP is a small multi-platform system for managing applications for a user or project environment. The user can, through a GUI or command line tool, choose which applications and versions they want to use. The project manager can specify allowed applications and versions of these the project members can select. The user can then select one of multiple environments to use at login or within a specific shell.
