Free internet communications engine software for linux

Ice, the Internet Communications Engine, is middleware for the practical programmer. A high-performance Internet communications platform, Ice includes a wealth of layered services and plug-ins. Ice means simplicity, speed, and power.
Ice is available under the terms of the GNU General Public License (GPL). Commercial licenses are available for customers who wish to use Ice with proprietary products. Please contact sales@zeroc.com for more information.
Ice is currently available for C++, Java, C#, Visual Basic, Python, and PHP, and is supported on various operating systems. Additional operating systems and languages will be supported in future releases.
Ice consists of the following packages:
Slice The Specification Language for Ice. Slice establishes a contract between clients and servers, and is also used to describe persistent data.
The Slice Compilers Tools to compile from Slice into target languages, such as C++ and Java, or to automatically generate documentation from Slice files.
Ice The Ice core library. Among many other features, the Ice core library manages all the communication tasks using a highly efficient protocol (including protocol compression and support for both TCP and UDP), provides a flexible thread pool for multi-threaded servers, and additional functionality that supports extreme scalability with potentially millions of Ice objects.
IceUtil A collection of utility functions, such as Unicode handling and thread programming. (C++ only.)
IceBox An application server specifically for Ice applications. IceBox can easily run and administer Ice services that are dynamically loaded as a DLL, shared library, or Java class.
IcePack A sophisticated server activation and deployment tool. With IcePack, the complex task of deploying applications in a heterogeneous computer network is dramatically simplified. Simply write a deployment descriptor in industry-standard XML, and IcePack handles the rest.
Freeze Freeze provides automatic persistence for Ice servants. With just a few lines of code, an application can incorporate a highly-scalable evictor that efficiently manages persistent objects.
FreezeScript It is common for persistent data types to change, especially in large software projects. In order to minimize the impact of these changes, FreezeScript provides inspection and migration tools for Freeze databases. The tools support an XML-based scripting capability that is both powerful and easy to use.
IceSSL A dynamic SSL transport plug-in for the Ice core. It provides authentication, encryption, and message integrity, using the industry-standard SSL protocol.
Glacier One of the most difficult challenges for object middleware systems is security and firewalls. Glacier, the firewall solution for Ice, greatly simplifies the deployment of secure applications. Glacier authenticates and filters client requests and allows callbacks to the client in a secure fashion. In combination with IceSSL, Glacier provides a powerful security solution that is both non-intrusive and easy to configure.
IceStorm A messaging service with support for federation. In contrast to most other messaging or event services, IceStorm supports typed events, meaning that broadcasting a message over a federation is as easy as invoking a method on an interface.
IcePatch A patching service for software distributions. Keeping software up-to-date is often a tedious task. IcePatch automates updating of individual files as well as complete directory hierarchies. Only files that have changed are downloaded to the client machine, using efficient compression algorithms.
Enhancements:
- Various additions, including redundant IceGrid registries.

SAP R/3 Communications Suite allows SAP R/3 servers to communicate with external devices such as fax and GSM modems by sending and receiving a fax or SMS.

SAP R/3 Communications Suite provides an easy configuration through a Web interface and a JMX console.

ALTSE is an alternative search engine technology.

It can index up to a couple million Web sites.

A search engine is a program designed to help find information stored on a computer system such as the World Wide Web, or a personal computer.

The search engine allows one to ask for content meeting specific criteria (typically those containing a given word or phrase) and retrieves a list of references that match those criteria.

Search engines use regularly updated indexes to operate quickly and efficiently. Without further qualification, search engine usually refers to a Web search engine, which searches for information on the public Web.

Other kinds of search engine are enterprise search engines, which search on intranets and personal search engines, which search individual personal computers.

Some search engines also mine data available in newsgroups, large databases, or open directories like DMOZ.org. Unlike Web directories, which are maintained by human editors, search engines operate algorithmically.

Most web sites which call themselves search engines, are actually front ends to other search engines owned by other companies. The typical user will often not know which underlying search engine they are using.

madlibs engine project is a MadLibs clone.

The madlibs engine is a tiny engine for MadLibs-like interactive stories. Basically, you enter different words of a certain part of speech.

The program pastes them into a story text, creating weird, funny, or stupid results.

It runs on anything from a line printer to an xterm.

Nelit2 Engine project is a game engine.
Nelit2 Engine is a game engine that uses a Model-View-Controller concept. All View-s classes was developed by me, and you can dont worrie about this.
Model-s classes also was developed by me, but you can modify it for your game or write new class and use Model class how abstract.
The engine uses some popular libraries such OpenGL and SDL.
It works on Unix systems and on Windows.
Enhancements:
- Decoding png, bmp, jpg texture-file.
- 3D mesh.
- Cubemap texturing.

The CheeseMusic engine is the core to most of the cheesetronic audio tools.
CheeseMusic Engine is a flexible and powerful set of components designed to aid in the programming of audio software.
Main features:
- Very fast fixed point mixing/resampling engine. (tops around 200 voices on my duron 850mhz)
- Support for custom Effect Buffers (and LADSPA too).
- Abstract DSP/MIDI layers with support for ALSA/JACK/OSS/Win32
- Support for synthesis helpers such as envelopes,LFOs,filters,ringbuffers,interpolators,declickers,etc
- GUI-Agnostic support thru "Property Bridges" with GTKmm and QT support (but most support is for Qt)
- Qt widgets for configuring many components, such as:
- Audio/Midi drivers.
- Resampler.
- Effect Buffers/Routing.
- Envelopes/LFO,etc.
- Midi-Input managers, with voice/bank/channel allocation and integration to the mixing engine
- Powerful framework for writing MIDI Synthesizers, as programming at voice level is only needed.
