AIS Parser SDK (Automatic Identification System) is a ship tracking network using VHF transponders. AIS equipped ships are transmitting their positions, destinations, names, cargo types, etc.
You can receive these transmissions using expensive AIS transponders, or receivers such as those available from Milltech Marine, SeaCAS and Y-Tronic. AIS transponders and receivers output the received information as serial data using AIVDM messages. These are described in the IEC 61993-2 specification, but they are very similar to NMEA 0813 messages output by GPS devices.
The AIS Parser SDK parses these packed serial messages into data structures containing all of the AIS information for each message type. It allows you to easily add AIS capabilites to your desktop and web products, saving you valuable development time.
The SDK consists of 3 C files to link into your project; you then pass serial data to the SDK and it returns data structures with all of the information from the message. The AIS message contents are documented by the ITU M.1371 and IEC 62287 specifications. You will need a copy of these to fully understand the data generated by the SDK.

Beltane is a web-based central management console for the Samhain file integrity / intrusion detection system. Beltane project enables the administrator to browse client messages, acknowledge them, and update centrally stored file signature databases.
Beltane requires a Samhain (version 1.6.0 or higher) client/server installation, with file signature databases stored on the central server, and logging to a SQL database enabled.
In a client/server installation of Samhain, you have individual hosts monitored by Samhain clients, and a central log server (called yule) where also the file signature databases are kept. Beltane enhances this setup by providing an interface to browse client messages, acknowledge them, and modify the file signature database for a client according to the file changes reported by that client.
As the Samhain daemon keeps a memory of file changes, the file signature database need only be up to date when the daemon restarts and downloads the database from the central server. Beltane allows you to use the information logged by the client in order to update the signature database.
Details
Beltane is a PHP4 (also works with PHP5) application, with some additional components written in C. PHP4 (or PHP5) may be compiled as Apache module or as CGI interpreter (Beltane is tested with Linux, Apache 1.3/2.0, PHP 4.3.4/5.0.3 used as CGI interpreter, suexec, no SSL, MySQL and PostgreSQL databases).
Beltane 2 can also be used with an Oracle database.
On the client side, Beltane requires a Javascript capable browser. Cookies must be enabled. We recommend Mozilla/Firefox, as it is rumoured to be the most standard-conforming browser, but most inferior browsers may work as well.
Documentation is provided as SGML and HTML files within the tarball. You are adviced to read the documentation before attempting to install Beltane.
Main features:
- Major performance and scalability improvements for reduced memory consumption, faster baseline database updates, and faster reload of the client panel
- Support for Oracle database (Beltane version 2.1.1 and above)
- Client Status Display (running/dead/unknown)
- Bulk Update from user-defined criteria like: the hostname, a list of files (with or without checksums), or a time window
- On-the-fly Sorting of the message list
- Message Filtering with POSIX regular expressions
- GnuPG Signing of client file signature databases after an update
- Search function for the database.
- Editing of client configurations
- Client Configuration Reload can be triggered
- Multiple Users with logging of login/logouts
- Server Messages can be viewed optionally
Enhancements:
- Multiple administrator accounts are possible, per-user configurability has been improved, and a strict locking policy has been implemented to avoid race conditions.

JGraph Layout Pro is the next generation of Java Graph Layout engine designed for optimal performance with the JGraph core. JGraph Layout Pro project has a flexibility and simple design, enabling you to use circular, tree and force-directed layouts with ease in your JGraph application.
Layout Pro comes with a developers guide and an example applet that demonstrates features such as auto-layout, collapsing/expanding of grouped cells, graph morphing and selective layouting of sub-graphs. Also available is a webstart version.
JGraph Layout Pro provides you with a fully supported layout code base that is actively developed and maintained by the core JGraph development team. Using Layout Pro gives you the added confidence of active bug resolution and developer documentation.
Main features:
- Functionality Pro layouts are designed to use the full set of JGraph features such as partial graph views, grouping, animating graphs as well as all the new optimal API calls available in the JGraph core.
- Documentation and source Layout Pro comes with full source and an up-to-date developers application note.
- Performance Designed from the base up for speed, the Pro layouts make auto-layouting possible on even larger graphs. The Layout Pro tree algorithm is 6-times faster over 25,000 nodes than its JGraph Addons equivalent, even with its additional features, such as support for collapsing tree branches.
- Stability The layout architecture for Layout Pro is based around the principle of complete flexibility. Not only does this help you achieve the functionality you want, also it provides you a solid API designed for stability and minimal changes between new versions. This means less migration effort between releases, so you can confidently upgrade.
- Value Layout Pro represents the best value for money for graph layout software. Combined with the supreme value of the core JGraph library, it makes an unbeatable combination.
Enhancements:
- The functionality for laying out nested groups has been fixed.
- The layout inter-rank spacing calculation in the hierarchical layout has been improved for a more closely spaced result.
- The boundary of the graph now includes edge control points, since it was previously possible to draw a graph where the control points were off the edge of the graph.
