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
- Skinable
- Open source (MIT/expat license)

Distributed Access Control System is a complete, light-weight, single sign-on and role-based access control system distributed under an open source license. It provides:
- extended authentication and role-based access control capabilities for Apache-based web services, CGI programs, and virtually any program or script;
- a wide array of flexible, modular, and efficient authentication methods, including two-factor authentication and hardware tokens;
- powerful, rule-based authorization checking that can be applied transparently to any resource or activity (such as web services, web content, and program features) by Apache-based web services and CGI programs, or virtually any program or script;
- an Apache 2.0/2.2 module, suite of CGI programs, and collection of command line tools for Unix-type platforms, such as Linux, FreeBSD, and Solaris.
Enhancements:
- This release includes an important bugfix to local_passwd_authenticate that prevents invalid passwords from being accepted.

LMS (LAN Management System) is the integrated system of networks management designed for various size internet providers (ISP).

That software writed in PHP, Perl and C, works with variuos database systems.

Inferno is a compact operating system designed for building distributed and networked systems on a wide variety of devices and platforms.
Inferno was originally developed at Bell Labs (the research division of Lucent Technologies).
Inferno Operating System is a well-designed, economical operating system particularly suitable for use in networked devices such as advanced telephones, hand-held devices, TV set-top boxes, and many other embedded applications.
Inferno can run in native mode on an embedded system or in emulation mode under many different operating systems. Inferno has many features in common with Plan 9.
Cross-Platform Portability
Inferno can run as a user application on top of an existing operating system or as a stand alone operating system. Most of the popular operating systems and processor architectures are supported:
Host Operating Systems:
- Windows NT/2000/XP
- Irix
- Linux
- MacOS X
- FreeBSD
- Solaris
- Plan 9
Supported Architectures:
- Intel x86 (386 & higher)
- Intel XScale
- IBM PowerPC
- ARM StrongARM (ARM & Thumb)
- Sun SPARC
Inferno also runs as a plug-in under Internet Explorer version 4 and higher. Each Inferno system presents an identical environment to the applications, irrespective of the underlying host OS or architecture, allowing the developer to work with a truly homogeneous environment across multiple different platforms.
Portable Applications
Inferno applications are written in Limbo, a modern, safe, modular, concurrent programming language with C-like syntax. It is more powerful than C but considerably easier to understand and debug than C++ or Java. Limbo code is compiled into architecture independent byte code which is then interpreted (or compiled on the fly) on the target processor. This means that any Inferno application will run identically on all Inferno platforms.
Transparent Resources
Inferno offers complete transparency of resources and data using a simple but powerful namespace system. By representing resources as files and having one standard communication protocol, resources such as data stores, services and external devices can easily be shared between Inferno systems. A resource interface may be imported to the local system and used by the applications without them knowing, or needing to know, whether it is local or remote.
Security
High level security is an important part of the Inferno system. By using one standard protocol for all network communication, security can be focused on one point and provided at a system level. Inferno offers full support for authenticated, encrypted connections using a certificate based user identification scheme and variety of algorithms including:
- IDEA, 56 bit DES, 40, 128 and 256 bit RC4 encryption algorithms
- MD4, MD5 and SHA secure hash algorithms
A Complete Solution
Inferno is not only an operating system, it is also a complete development environment, providing all the tools necessary for creating, testing and debugging the applications that run within it.
- Acme IDE: includes editor, shell, advanced pattern matching tools & more
- Fast Compiler: with full syntax and compile time type checking
- Graphical Debugger: with full stack trace for currently executing threads

KIWI Image System provides a complete operating system image solution for Linux supported hardware platforms as well as for virtualisation systems like Xen Qemu or VMware. The KIWI architecture was designed as a two level system. The first stage, based on a valid software package source, creates a so called physical extend according to the provided image description. The second stage creates from a required physical extend an operating system image. The result of the second stage is called a logical extend or short an image.
A normal installation process is starting from a given installation source and installs single pieces of software until the system is complete. During this process there may be manual user intervention required. However an operating system image represents an already completed installation encapsulated as a file and optionally includes the configuration for a specific task. Such an operating system starts working as soon as the image has been brought to a system storage device no matter if this is a volatile or non volatile storage. The process of creating an image takes place without user interaction.
This means all requirements of the encapsulated system has to be fulfilled before the image is created. According to this the so called image description tree stores all the information needed to create an image.
Main features:
- Distribution independent
- Support for virtualisation systems like Xen
- Support for deploying images over the network
- Support for VMware / Qemu images
- Support for USB-Stick systems
- Support for LiveCD/DVD systems
- Centralized image description based on XML
- Prebuild boot images for SUSE systems
- Prebuild PXE configuration usable with kiwi netboot images
- SUSE Linux on a 128MB flash card.. yes thats possible
