CD-Rchive2 is a complete revamp of the popular but now aged CD-Rchive program. It is intended to be used with cdrecord-ProDVD, cdda2wav, and mkisofs for the production of data and music CDs and data DVDs. Built in tools allow cloning of a complete CD or DVD and writing copies. A Boot Wizard will guide you through steps required to make a bootable CD or DVD, write the code, and compile a binary menu program which runs with isolinux. (If this software suddenly stops working, there is a good chance your cdrecord-ProDVD key has expired; get a new one from the site.)
cgi-util is a fast, easy to use C library for creating CGI programs. Functions are available for initialization (parsing), grabbing fields (by string, integer, double or boolean value), embedding HTML files, and more. It accepts both POST and GET request methods and has extensive error handling.
CGI::Application is a Perl framework intended to make it easier to create sophisticated, reusable Web-based applications. This module implements a methodology which can make Web software easier to design, easier to document, easier to write, and easier to evolve. CGI::Application builds on standard, non-proprietary technologies and techniques, such as the Common Gateway Interface and Lincoln D. Stein's excellent CGI.pm module. CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system, or Web server.
chrony is a client and server for the Network Time Protocol (NTP). This program keeps your computer's clock accurate. It was specially designed to support systems with intermittent Internet connections, but it also works well in permanently connected environments. It can also use hardware reference clocks, the system real-time clock, or manual input as time references.
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.
ColdSync is a portable synchronization tool for Palm devices (PalmPilot, Handspring Visor, etc.) that runs under *BSD, Solaris, Digital Unix/Tru64, Linux, AIX, and Windows NT. It supports PalmOS 2.0 (original PalmPilot) and later. It is only known to support Visor syncing under FreeBSD and Linux, however. It supports IR syncing under Linux. ColdSync can back up, restore, install, and synchronize database, and can be extended and customized through the use of conduits. ColdSync is rather paranoid and takes pains not to delete anything it isn't 100% sure about.
CTSim is a Computed Tomography simulator. It simulates the process of obtaining x-ray data around a phantom object. It then uses various reconstruction algorithms for reconstructing the original image. It supports animation of projection and reconstruction processes, 3-dimensional viewing using OpenGL as well as cross platform support using GTK and Win32.
DansGuardian is a Web content filtering proxy that uses Squid to do all the fetching. It filters using multiple methods including, but not limited to, phrase matching, file extension matching, MIME type matching, PICS filtering, and URL/domain blocking. It has the ability to switch off filtering by certain criteria including username, domain name, source IP, etc. The configurable logging produces a log in an easy to read format. It has the option to only log text-based pages, thus significantly reducing redundant information (such as every image on a page).
