Web100

The Web100 project was created to produce a complete host-software environment that will run common TCP applications at 100% of the available bandwidth, regardless of the magnitude of a network's capability. Web100 has endowed TCP with better instrumentation. This instrumentation is the foundation for both the TCP autotuning performed in process-level code and the process- level tools designed to locate bottlenecks within the following major subsystems: the sending application, the sending OS, the Internet path, the receiving OS, and the receiving application. Measurement tools have also been built on this instrumentation to display performance indicators to end-users, as well as provide internal diagnostics for network and system administrators.

NewsForge: Version Control for Non-Programmers with Subversion

"Imagine a utility that lets you make an annotated backup of any of your project files with the click of a mouse or a single command. It would let you review the history of your backups and recover any version you wished. And it would integrate with your file browser and would keep track of files that have changed since your last backup. The utility exists--Subversion, and its companion program TortoiseSVN, can help you safely manage your files as you work with them.

"Subversion is one of a class of programs that has been used by programmers for decades: the source code control system, which developers use to manage changes to program source code. Such software has features that enable large teams to work in a distributed environment on the same files while keeping track of who has done what, and when..."

The Linux Intrusion Detection System (LIDS)

The Linux Intrusion Detection System (LIDS) is a patch which enhances the kernel's security by implementing a reference monitor and Mandatory Access Control (MAC). When it is in effect, chosen file access, all system/network administration operations, any capability use, raw device, memory, and I/O access can be made impossible even for root. You can define which programs can access specific files. It uses and extends the system capabilities bounding set to control the whole system and adds some network and filesystem security features to the kernel to enhance the security. You can finely tune the security protections online, hide sensitive processes, receive security alerts through the network, and more.
