xlife is a laboratory for experimenting with cellular automata. It supports loadable rulesets and palettes, different topologies, and up to 256-state cellular automata. It has rules and patterns for Life, Brian's Brain, Perrier's Loops, Langton's Ants and Loops, Wireworld, E.F. Codd's 1975 UCC automaton, some Prisoner's Dilemma games, and many others. It is very fast for step-by-step mode, bounded grid, and chaotic patterns. It has several unique features: a historical mode, a pseudocolor mode, and n-state statistics. It has been developed since 1989. The modern version of Xlife began its history in 2011.
fupids2 is a so-called human oriented IDS based on the FUPIDS project. fupids2 calculates an attacker level for every user on all Unix/Linux/BSD systems in the network. It looks at the behavior of the user (the programs the user uses, the daytime the user is active, the building and room the user uses, the part of the room in which the user sits, and so on) and reports if the user engages in behavior that is unusual for that person. This method can often detect accounts overtaken by attackers.
muhttpd (mu HTTP deamon) is a simple but complete Web server written in portable ANSI C. It supports static pages, CGI scripts, and MIME type based handlers. It drops privileges before accepting any connections, and can log received requests. It has been tested on OpenBSD, GNU/Linux, NetBSD, FreeBSD, Mac OS X, and Cygwin. It runs successfully on 32-bits, 64-bit, little endian, and big endian systems.
Kradview is a viewer of images obtained from different sources such as X-ray, NMR, and DICOM-compatible imaging devices. Its aim is to be an easy-to-use DICOM viewer with instant rendering of images, no matter the size and the zoom of the DICOM image. It allows medical professionals to view X-ray images easily.
Hiawatha is a secure and advanced Web server for Unix. It has been written with security as its main goal. It features advanced access control, prevention of SQL injection and cross-site scripting, banning of clients who try such exploits, the ability to run CGIs under any UID/GID you want, and many other features. These features make Hiawatha an interesting Web server for those who need more security than what the other available Web servers are offering. Hiawatha is also fast and easy to configure.
GODI provides an advanced programming environment for the Objective Caml (O'Caml) language. From INRIA (who created O'Caml) you can get the O'Caml compiler and runtime system, but this is usually not enough to develop applications. You also need libraries, and there are many developers providing them. But it is a lot of work to build and install them. GODI is a system that simplifies this task: It is a framework that automatically builds the O'Caml core system, and additionally installs a growing number of pre-packaged libraries. For a number of reasons, GODI is a source-code based system, and there are no precompiled libraries, but it makes it very simple for everybody to compile them.
PDFTextStream is a PDF text and metadata extraction library available for Java and .NET. It supports all versions of the PDF document specification (including v1.7, used by Acrobat 8, 9, and X), extraction of text encoded using double-byte character sets (including Chinese, Japanese, and Korean), decryption of documents encrypted using 40-bit, 128-bit, 256-bit, and variable bit length ciphers, and extraction of all document metadata provided by PDF documents (including form data, bookmarks, and annotations). Easy integration with Jakarta Lucene is included, as well as interactive form update capability.
