Free subversion version control system software for linux

The Bazaar Revision Control System is a changeset-oriented revision control system based on Arch that makes it possible to retain previous changes to projects and coordinate development with other developers.
Its goal is to speed development of an upwards- compatible version of Arch.
Main features:
- All the transparent and robust storage features of GNU Arch.
- seamless upgrade path to [WWW] bazaar-ng
- direct support for URLs - one command can checkout or merge from remote locations.
- integrated GPG support - zero setup for most signed archive situations
- faster - checkout, most local operations, commits
- svn-like diff, switch, import, export, log commands
- Explicit tracking of conflicts, preventing accidental commits of files with conflicts
- single merge command that allows merging between arbitrary branches.
- Daily builds of the latest code (Downloads).
- fully compatible with tla - drop in and start using
- supports debian version numbers in branch names
- annotate support
- internationalised via gettext and [WWW] Rosetta.
- Python bindings.
Enhancements:
- More Solaris fixes.
- SSL support and ~/.authinfo support.
- Many UI tweaks.
- A number of bugfixes.

Trac is an advanced tool for tracking software development projects. It provides a simple wiki, issue tracking system and tight integration with the Subversion revision control system. Trac/Subversion Development JumpBox bundles Trac 0.10.4 and Subversion 1.3.1.

WHY USE A JUMPBOX

Its Simple

Open Source applications are great. The applications are powerful, inexpensive and get the job done. But installing and configuring those applications can be a pain. A JumpBox delivers Open Source applications in a way that makes them simple to try, run and operate.

Its Quick

Actually downloading a JumpBox will take the most time. Once thats done, youre just a few minutes from having a working application that can serve multiple users.

Its Portable

A JumpBox collects the application, application dependancies and all application data into a single bundle that can easily be moved from one computer to another. This allows you to start running the application on your desktop and then as usage grows move it to a server without needing to reinstall or reconfigure. Plus with support for Mac OS X, Windows and Linux you can even move the application between platforms with little effort.

Its Safe

Manually installing Open Source applications not only takes a lot of time and effort, but when youre done its still left to you to figure out how to protect the data the application manages. With a JumpBox its easy to add automatic backups of the entire state of the application.

Its Virtual

A JumpBox application is a virtual appliance that bundles the open source application and all its runtime dependancies into a single package that runs on top of virtualization software from VMWare, Parallels or Xen. This means all JumpBox applications automatically gain the benefits of traditional server virtualization and can be dropped into existing virtualization infrastructure when available.

Its Comfortable

JumpBox provides a consistent runtime environment for all applications that we bundle. The applications may differ considerably, but their installation and operation will be familiar no matter which JumpBox you choose.

active acoustic vibration control tool is a set of basic tools for monitoring and modulating audio noise.

The tools aim toward a set of codes and algorithms for monitoring noise signal and modulation and reducing them using active noise control priciples.

Active noise control and soundproofing is a relativly recent development (first researched around 30 years ago), and has been in constant development for many and varied situations and applications.

The basic concept of active noise control is the aplication of equal and opposite force to cancel out vibration.

The project attempts to provide a starting point and library for experimentation into various methods of digital signal processing for active noise reduction and soundproofing.

Noise cancellation has been used in many environments currently active control is best used in constant vibrations with lower frequencys.

The principle is of controlling the noise level by adding an equal and opposite sound to the noise in the environment. The basic principle may be simple but the actual effectivness depends on many environmental factors.

Generally simplistic out of phase sound wave is used which works to some extent and requires little processing (a simple XOR with -1) this will tend to leave a large number of artifacts as the amplitude of higher frequency components (above i->o delay time) rises.

i->o processing delay
e transducer efficiency
p sound propagation characteristics
r reflections

The project aims to provide a framework for many dsp architectures, dac/adc chips, transducers and monitors.

Create tools for acoustic calibration and data logging hardware
To simplify implementation of active noise and vibration control systems.
To provide an open source standard for use within the industry and education.
To encourage hardware producers to distribute standard interface descriptions for their hardware
Enable low cost development of systems using COTS consumer hardware for noise and vibration control.

Distributed Concurrent Versioning System (DCVS) project extends the well-known version control system CVS and the file distribution and synchronization program CVSup with functionality to distribute CVS repositories with local lines of development and handle synchronization of the distributed repositories automatically in the background.
Development lines (branches) are owned by a repository server, repository servers efficiently update each other via CVSup, and CVS ensures correct server use on checkin and branch creation.
Enhancements:
- This release adds miscellaneous bugfixes and the security patches of CVS 1.12.13.
- There are now installation packages for Windows to be installed on Cygwin, for SUSE Linux 10, for FreeBSD 4, 5, and 6, and for Fedora Core 4.

Sitellite Content Management System is an advanced Web-based Content Management System (CMS) and PHP content publishing framework.
Main features:
Cross-Platform WYSIWYG editor
- Sitellite lowers the learning curve of Content Management to the point of being Grandma-friendly, without sacrificing standards-compliance.
"Undo" button!
- Never lose a change or delete a page by accident again! Sitellite keeps every change you make in its automatic version control system.
Most advanced Access Control in PHP
- Sitellite makes it as easy as it should be to implement multi-role privileges into your web site.
Most advanced development model in PHP
- At the core of Sitellite are two Enterprise-scale components: The Sitellite Application Framework and the Sitellite Content Server. These make Sitellites power and flexibility unparallelled in the PHP world.
Built-in multi-lingual help system
- Users know how important help is, and so do we! Thats why we built into Sitellite a top-notch help system that add-on developers can also take advantage of.
Enhancements:
- IE7 is supported.
- Form spam abuse is prevented with CAPTCHA, blacklists, etc.
- Integration with Snipshot.com was added for image editing.
- Coral cache is used for traffic surge protection.
- File download statistics are available.
- The cache is automatically flushed to keep the site cache in sync.
- Google Maps and Google Site Maps were integrated.
- Many user interface improvements were made.
- SEO improvements were done, including more control over URLs.
- Many bugs were fixed.
