Free inventory control system software for linux

A Simple Version Control System is an easy to install and easy to to use version/revision control system.
ASVCS differs from most other version control systems in that ASVCS is designed to keep track of files in place. ASVCS does not allow any changes to be made to files, all changes require the users to change files externally with FTP or SSH access.
ASVCS is very easy to setup and use. Users do not need to work with repository, branches, commit and check-out files. All a user needs to do is upload the changes files and click Update or if enabled just wait for it to be updated automatically.
ASVCS is ideal for small projects or personal use, though it can also be used by large project how do not need or want the complexity of most version control systems.
Main features:
- asy to install and use
- Written in PHP
- Can track binary or text files
- Automatic file tracking (requires cron support)
- Diffs of revisions
- Easy user access management
- Entirely Web based

H-inventory project was developed to meet the needs for a training center of network administrators.
Indeed, the stations are redeployed every week and are not linked to active directory, those are renamed each week so we cannot base us on the name.
The problem is thus the identification of the machine. We thus decided to base us on the concatenation of all the MAC addresses of the machine.
Enhancements:
- Inventory Quick Search Multiple edition of extra fields Cron synchronization Default Location Auto location by script Statistics filtered by locations
- Incidents Quick search Edition and deletion Archiving Multiple incidents types and subtypes
- Monitoring Cron to automate monitoring and audit
- Knowledge Base New
- Deployment Interface and DB improvement New installation method with the 0.2 version of the client
- Admin Maintenance (tar xml files to obtain some space)
- General New installer All interfaces reviewed
- Development (to improve the facility to extend the application) Bug corrections Full php5 object now Comments on code Xhtml 1.0 strict

Sample Inventory Program provides a laboratory inventory management system (LIMS) for Zope.
Many integration tests exist for various aspects of the SIP application, ranging from command line importing of samples and project configuration to CSV Web-based importing of sample modifications.
Main features:
- Cross platform using the Zope 3 appliation server and Python language. Contains over 200 unit and integrations tests.
- Command line import functionality (import application configuration, projects, samples, aliquots and container heirarchies)
- Cross project searches based on Subject Ids, Other Ids, Additional Sample Data, and Sample Types. Uses REPORT Permission.
- Search Form Screenshot
- Project level permissions. Users can be enabled/disabled by removing User Permission in the Applicaiton root. Lab Technician Permission allows users to put contents into a shipment and add/modify Samples. Project Manager permission allows project configuration as well as administering Users for specified projects.
- User and Permission Screenshot
- 100% Web based interface (IE, Mozilla, Safari tested). QT based client in development.
- Projects Overview Screenshot
- Ability to Split Aliquots into smaller units and put them into separate physical containers.
- Ability to Derive Aliquots into other Sample Types. Derived Samples/Aliquots links to their origin sample.
- Locations/Containers are heirarchical and can be restricted to a Project
- Shipments act as virtual containers where Lab Technicans can split aliquots into. AlsocShipments contain Contact Info, Shipping Info and Funding Info. While the Shipment Status will control the status of the Shipment moving from: Incomplete, In-Transit, and finally Received based on date fields being filled out.
- Shipment Screenshot
- Understandable relational model that enables simple reporting to be easily constructed by third party tools such as Jasper Reports
- Batch editing available using CSV files. All changes are transactional. You can easily import hundreds of samples into multiple projects by using CSV files and importing them through the web interface. You can change locations of aliquots by using the CSV import functionality. Any functionality that can be done in the web interface is complimented by CSV functionality.
- Project Search Results Screenshot
- Ability to administer Sample Type, Container Type, Locations and Unit of Measure at the application level to enforce standards across all Projects. Requires Application Manager permission.
- Ability to assign Sample Type, Locations, Technicans in a Project by Project basis.
- Project Administration Screenshot
- Advance Attribute Capture forms enable Project Administrators to specify what attributes for their Sample Types need to be captured for their project. Now non-technical users can ensure that Lab Technicans capture any attribute for any Sample Type. Attributes are limited to: DateTime, Boolean, Float, Integer, String and Text fields. Default Values can be assigned.
- Sample Type Attributes Screenshot
- Finally Sample Type Attributes can have validation scripted on a field by field basis. By using the TALES Validation functionality for Sample Type Attribute Fields. Examples of TALES validation:
- python: value < 100 # value of the field is less than 100
- python: value < datetime.date(2006, 10, 31)
- # value of the field is less than 10/31/2006
- Edit Comments will require a comment to be added to any field that is edited. These are used in conjunction with RDBMS triggers to keep a audit log to ensure that all changes to all inventory can be tracked.

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.

AstroCam is a C based Stepmotor Control system including a PHP-Webinterface.
The first AstroCam version was released in Dec 2001 and was written in C+Tcl/Tk. After i saw, that the combination of Tcl/Tk and C code wasnt a good thing, I wrote a CGI webinterface and a Gtk GUI. A few years later, I removed both parts, rewrote AstroCam completely, built an PHP webinterface and changed the communication system between its components to message queues.
Main features:
Supported Operating Systems:
- OpenBSD i386
- NetBSD i386
- FreeBSD i386
- Linux 2.2/2.4/2.6 i386
Supported Browsers:
- All browsers with IFrame-support (e.g. Konqueror, Internet Explorer, Mozilla/Firefox) should work. Netscape 4.x doesnt work.
Enhancements:
- The installer now can handle directories of the MyServer webserver too.

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.
