WindowBuilder is a powerful and easy to use bi-directional
Java GUI designer that makes it very easy to create Java GUI
applications without spending a lot of time writing code to
display simple forms. With WindowBuilder you can create
complicated windows in minutes. Use the visual designer and
Java code will be generated for you. You can easily add controls
using drag-and-drop, add event handlers to your controls, change
various properties of controls using a property editor,
internationalize your app and much more.
JGraph is the most powerful, lightweight, feature-rich, and thoroughly
documented open-source graph component available for Java. It is accompanied
by JGraphpad, the first free diagram editor for Java that offers XML, Drag and
Drop and much more!
With the JGraph zoomable component, you can display objects and relations
(networks) in any Swing UI. JGraph can also be used on the server-side, for
example to read a GXL graph, apply a custom layout algorithm, and return the
result as a HTML image map.

MX4J is a project to build an Open Source implementation of the
Java(TM) Management Extensions (JMX) and of the JMX Remote API
(JSR 160) specifications, and to build tools relating to JMX.
JMX is an optional package for J2SE that provides a standard
way to manage applications. It can also be used to wrap legacy
systems and provide a standard interface to the outside world,
enabling the development of web services. JMX allows developers
to write more modular and loosely coupled system components and
reduce the complexity of large, interoperating systems.
Squirrel is a high level imperative/OO programming language, designed
to be a powerful scripting tool that fits in the size, memory bandwidth,
and real-time requirements of applications like games. However Squirrel
offers a wide range of features like dynamic typing, delegation, classes
& inheritance, higher order functions, generators, coroutines, tail
recursion, exception handling, automatic memory management, weak
references, etc.
Squirrel is inspired by languages like Python, Javascript and especially
Lua. The API is very similar and the table code is based on the Lua one.
Heirloom mailx (formerly known as "nail") is derived from Berkeley
Mail and provides the functionality of the System V and POSIX mailx
commands. Additional features include support for MIME, IMAP
(including caching and disconnected use), POP3, SMTP, S/MIME,
international character sets, maildir folders, message threading,
powerful search methods, scoring, and a Bayesian junk mail filter.
Mailx can be used as a mail batch language in nearly the same way as
it is used interactively. It can thus act as a mailbox filter, can
fetch mail from remote accounts, and can send files as attachments.
This program is for any user who retrieves ftp files via
ftpmail or bitftp servers. It runs quietly in the background
and watches the user's mail directory. When the mail-
retrieved file has arrived in full, rftp puts the pieces
together in order and stores the tarball in a directory.
I wrote this several years ago when my only link to the
Arpanet was a uucp link. These days, most FreeBSD users
have a direct link to the net. For the dozens or hundreds
who don't this should be of use.
CLN is a library for computations with all kinds of numbers. It has a
rich set of number classes:
- Integers (with unlimited precision),
- Rational numbers,
- Floating-point numbers:
Short float,
Single float,
Double float,
Long float (with unlimited precision),
- Complex numbers,
- Modular integers (integers modulo a fixed integer),
- Univariate polynomials.
The subtypes of the complex numbers among these are exactly the types
of numbers known to the Common Lisp language. Therefore CLN can be used
for Common Lisp implementations, giving `CLN' another meaning: it
becomes an abbreviation of "Common Lisp Numbers".
Agda is a dependently typed functional programming language: It has inductive
families, which are similar to Haskell's GADTs, but they can be indexed by
values and not just types. It also has parameterised modules, mixfix operators,
Unicode characters, and an interactive Emacs interface (the type checker can
assist in the development of your code).
Agda is also a proof assistant: It is an interactive system for writing and
checking proofs. Agda is based on intuitionistic type theory, a foundational
system for constructive mathematics developed by the Swedish logician Per
Martin-Lof. It has many similarities with other proof assistants based on
dependent types, such as Coq, Epigram and NuPRL.
Yacas (Yet Another Computer Algebra System) is a small and highly flexible
general-purpose computer algebra language. The syntax uses a infix-operator
grammar parser. The distribution contains a small library of mathematical
functions, but its real strength is in the language in which you can easily
write your own symbolic manipulation algorithms. The core engine supports
arbitrary precision arithmetic (although it can optionally be linked with
the library "libgmp3") and is able to execute symbolic manipulations on
various mathematical objects by following user-defined rules.
