The ROHC library provides an easy and robust way for applications to reduce their bandwidth usage on network links with limited capacity or expensive costs. Headers of network packets are compressed with the ROHC protocol and algorithms. The ROHC protocol is very efficient for compressing VoIP streams which use RTP as a transport protocol. ROHC is also suitable for compressing IP-only (IPv4 or IPv6) flows, UDP flows, and many others.
jPDFNotes is a Java bean component which can be integrated into Java applications or deployed on the Web in an applet or using Java Web start. It allows users to mark up, review, and annotate PDF documents online. Most PDF annotations and features are supported, including graphical, sound, free text, typewriter, measurements (distance, perimeter, and area), file attachments, and bookmarks. All PDF fonts are supported (Types 0-3, OpenType, and TrueType).
YAGAC is a library that when linked to your C program, allows you to conveniently track or trash memory leaks within your application while it is still running. You can have multiple garbage collectors according the code part you are in. It tracks memory assigned by your code only, and does not monitor third part libraries. Tracking can be activated by updating a debug flag without restarting your application. It is intended for use with daemon-type programs.
libjson is a JSON parser and printer that is fully compliant with the JSON spec. The parser is efficient and interruptible with a simple and flexible API. It also optionally supports extensions like C-style comments or Python/YAML style comments, and for security allows the user to set a limit on the number of nested structures and the parse buffer. The library plugs easily into any model since it doesn't include any object model, and plugs easily in any project's memory management since the memory functions can be redefined.
EpochX is a genetic programming framework. It is designed specifically for the task of analyzing evolutionary automatic programming, so is ideal for researchers who require an extendable system for studying the effects of new operators or procedures. It supports 3 popular representations - Strongly-Typed tree GP, Context-Free Grammar GP, and Grammatical Evolution.
The ReportLab Toolkit is a library for programatically creating documents in PDF format. It can quickly and easily create or automate complex, data-driven documents. It features a real document layout engine, flowable objects (such as paragraphs, headlines, tables, images, and graphics), support for embedded Type-1 or TTF fonts, support for Asian, Hebrew, and Arabic characters, support for bitmap images in any popular format, support for vector graphics, a library of reusable primitive shapes, and an extensible widget library. It includes simple demos and more complex tools. It allows for any data sources.
Syncless is an experimental, lightweight, non-blocking (asynchronous) client and server socket network communication library implemented in Stackless Python 2.6. It contains an asynchronous DNS resolver (using dnspython) and an HTTP server capable of serving WSGI applications. It aims to be a coroutine-based alternative of event-driven networking engines (such as Twisted and FriendFeed's Tornado). It is already about that fast, but it has fewer features and is less stable now.
