Free balancing act software for linux

Big Calc is a Kommander version of my oversized, high visibility calculator.

I am learning several scripting and programming languages, and a calculator is usually my first learning project.

This version is basic and does not act the way I want to yet, but I thought it might be useful for someone. I hope you enjoy!

libredblack is a library to provide the RedBlack balanced tree searching and sorting algorithm.

The algorithm was taken from the book "Introduction to Algorithms" by Cormen, Leiserson & Rivest. Frankly I never entirely understood it, but it most definately works!

What is the problem with normal binary trees?: A standard binary tree only works well if the original data is provided in a random order (random in terms of the key being sorted on). If however the data is provided in order, then the tree becomes very un-balanced and searches degrade into nothing more than a linked list.

How is the RedBlack tree different?: The RedBlack tree acts in a way to keep the overall tree fairly balanced as new data is loaded in.

How does it work?: The tree is always organised such that it has the following properties:

Every node is either Red or Black.

A leaf node (a dummy empty node at the end of the tree) is always Black.
If a node is Red then its children are Black.

Every path from the root to a leaf contains the same number of Black nodes.
So from 3 & 4 above, we can see that the longest path (alternating Red and Black nodes) is only twice as long as the shortest path (all Black nodes). Thus the tree remains fairly balanced.

Great! How does it maintain those properties?: Ah, well, thats where I get a bit hazy. I know that it does this by adding Red nodes and then rotating the tree elements and changing the colours to sort out times when two Red nodes become parent-child (breaking rule 3).

nionet is a complete client/server VPN solution for raw ethernet tunnels. Clients are available for Linux and Windows; the server is Linux only.
Due to its object oriented architecture, it is possible to easily plug in new transports. So far it features UDP and DNS tunneling. Being an ethernet layer 2 bridge, several network segments can be connected transparently.
When used in an ISP environment, nionet allows per-user traffic-shaping and precise reporting of used bandwidth. On the fly load balancing is possible. nionet uses sqLite or MySQL for account storage; changes to accounts are immediately active.
Main features:
- Compatible with all protocols that work over 802.3 Ethernet
- Uses mySQL or sqlite as backend for user accounts and session log
- Includes traffic accounting and billing for usage in an ISP environment
- Built-in traffic-shaper allows individual bandwidth-limits
- Values in the database can be changed in flight - e.g. new shaper-values will be activated during a running session. This allows dynamic load balancing.
- Built-In fragmentation - full Ethernet MTU of 1514 is tunnelled
- Transport via UDP or DNS
- Uses a virtual Ethernet adapter to be compatible with all existing software (Linux tap-driver, Windows NDIS driver)

Stencil is a library for developing web-based applications in C++.
It includes request and response objects, a skinnable template engine, server api abstraction, and facilities for load balancing, browser jogging, security and catching runaway CGIs.
Stencil library also includes some useful Javascripts and images.
Stencil is the successor to Groundwork.
Enhancements:
- Fixes a multipart form processing bug.
- All methods use (u)int(16|32|64)_t types rather than (unsigned )(short|long|long long) types.

USBSink is a GNOME program for file synchronization over USB. USBSink is designed for users of removable drives, such as flash drives or external hard disks.

The goal is to have a complete automation of data trasfers, after a task has been defined. With file monitoring and hardware detection features, USBSink is able to respond and act according to relevant events across the desktop.

Open Proxy Scanning Bot (formerly NeoBOPM) is a loadable module for the NeoStats IRC Services. Open Proxy Scanning Bot scans clients connecting to the IRC network for insecure proxies, and also looks up a DNS blacklist for previously registered insecure proxies.
It caches the results of scans to increase perfomance, and with multiple bots, can be configured for load balancing.
It currently supports Hybrid7, Unrealircd, LiquidIRCd, Bahamut, QuantumIRCd, MysticIRCd, NeoIRCd, and Ultimate, with support for other ircds planned.
Enhancements:
- The code was updated to support NeoStats 3.0 Alpha 3.
- The DNS blacklist code was split out to a new module, BLSB.
- Several issues regarding NeoStats consuming 100% CPU when using OPSB have also been corrected.
- gcc 4.0 support was fixed.

dANN library can help create artificial neural networks within other programs. It is currently written in Java, C++, and C#. However, C++ and C# versions can only be obtained through the SVN at the moment.
Also, the C++ and C# versions are not properly documented and cleaned up, although they work. The Java version of the library is well documented and packaged in binary and source form.
The intent is to provide a powerful interface for programs to include artificial neural network technology into their code. It will also act as a testing ground for research and development of new AI concepts.
Enhancements:
- This release was updated to work with the new library layout.
