BlockHosts is a script to record how many times a local system is attacked, based on configurable scanning of system logs for sshd or other services. When a particular IP address exceeds a configured number of failed login attempts, that IP address is blocked using hosts.allow files, or by using null-routing, or by using packet filtering. An email notification facility is also available.
ErfurtWiki is a fast, user-friendly, and highly configurable hypertext management system. It can store its pages and binary content with MySQL, PEARDB/dbx/ADOdb, dba/dbm, PHP-RPC, or flat file databases. It stands out from similar Wiki implementations in that it allows very easy integration into existing Web sites, features case-insensitive WikiLinks, extensive CSS support, multiple admin tools, is not GPLed, and includes documentation. There are over 200 extension plugins, but everything could still be compacted into one core "library" for easier installation and handling. It is useful for larger sites as well as lightweight backend for private homepages, due to its simple image uploading feature.
Steel Bank Common Lisp is a development environment for Common Lisp, with excellent support for the ANSI standard: garbage collection, lexical closures, powerful macros, strong dynamic typing, incremental compilation, and the famous Common Lisp Object System (multimethods and all). It also includes many extensions, such as native threads, socket support, a statistical profiler, programmable streams, and more. These are all available through an integrated, interactive native compiler which feels like an interpreter. SBCL is unique in being a multiplatform native compiler which bootstraps itself completely from source, using a C compiler and any other ANSI Common Lisp implementation.
CMUCL is a free, high performance implementation of the Common Lisp programming language which runs on most major Unix platforms. It mainly conforms to the ANSI Common Lisp standard. CMUCL provides a sophisticated native code compiler; a powerful foreign function interface; an implementation of CLOS; the Common Lisp Object System; which includes multimethods and a metaobject protocol; a source-level debugger and code profiler; and an Emacs-like editor implemented in Common Lisp. CMUCL is maintained by a team of volunteers collaborating over the Internet, and is mostly in the public domain.
SCaVis is an environment for scientific computation, data analysis, and data visualization designed for scientists, engineers, and students. The program can be used for function and data plotting in 2D and 3D, histograms, statistical analysis, and symbolic calculations using the Matlab/Octave high-level interpreted language.
Moosic is a music player that focuses on easy playlist management. It consists of a server process that maintains a queue of music files to play and a client program which sends commands to the server. The server continually runs through its playlist, popping items off the top of the list and playing each with an external program. The client is a simple command-line utility which allows you to perform powerful operations upon the server's queue, including the addition of whole directory trees, automatic shuffling, and item removal according to regular expressions. The server comes configured to play MP3, Ogg, MIDI, MOD, and WAV files.
