Free concept software for linux

Concepts project is a C++ class library for solving elliptic partial differential equations (PDEs) numerically.

The design principle is the transfer of mathematical objects and grammar used to specify mathematical and numerical models of physical systems isomorphically into simulation software.

The design realization uses the C++ functionality of inheritance and derived classes.

Emnu, new menu for KDE(proof of concept) is a proof of concept I finished at aKademy.

It is a new menu idea.

dnd any files to the startmenu.
dnd any desktop files(shortcut) to the startmenu.

drop quicklauncher and panel buttons.

.....

This is a idea, some codes is toke from baghira sidebar and xkmenu.

Dirty enough, just hack on kbutton.

WordNet project is a large lexical database of English, developed under the direction of George A. Miller. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept. Synsets are interlinked by means of conceptual-semantic and lexical relations.
The resulting network of meaningfully related words and concepts can be navigated with the browser. WordNet is also freely and publicly available for download. WordNets structure makes it a useful tool for computational linguistics and natural language processing.

The Falcon project is an open firewall project with the intention of developing an independent firewall system. [COPYRIGHT-1]

Falcon consists of different modules:
Falcons own proxies (generic TCP-Proxy and application specific proxies)
Squid for web access and caching (modified package for Linux)
BIND-8 for nameservice (coming soon)
qmail for mail communication
OS hardening (coming later)

The concept behind Falcon is pretty simple. It consists of three main parts:

Self-written proxy applications and configure-/logging facilities. These are all
written in Perl.

Third party applications like BIND, Squid, Qmail.

Concepts/instructions/tools for hardening the OS you want to run Falcon on.

Some third party proxies maybe replaced by self-written ones in the future (its up to you

mod_stencil is intended as the "reverse" of server-side includes / mod_include: Instead of having each file include a standard header/footer, all you do is specify the data in the datafile.

When this datafile is requested, mod_stencil will open the stencil/template file, and substitue the data values from the requested value into the stencil. The result is sent to the user.

This module is similar in concept as mod_design, however this is as an Apache 2 module instead of an Apache 1 module.

Net::Server is an extensible, general Perl server engine.
SYNOPSIS
#!/usr/bin/perl -w -T
package MyPackage;
use Net::Server;
@ISA = qw(Net::Server);
sub process_request {
#...code...
}
MyPackage->run(port => 160);
exit;
Main features:
- Single Server Mode
- Inetd Server Mode
- Preforking Simple Mode (PreForkSimple)
- Preforking Managed Mode (PreFork)
- Forking Mode
- Multiplexing Mode using a single process
- Multi port accepts on Single, Preforking, and Forking modes
- Simultaneous accept/recv on tcp, udp, and unix sockets
- Safe signal handling in Fork/PreFork avoids perl signal trouble
- User customizable hooks
- Chroot ability after bind
- Change of user and group after bind
- Basic allow/deny access control
- Customized logging (choose Syslog, log_file, or STDERR)
- HUP able server (clean restarts via sig HUP)
- Dequeue ability in all Fork and PreFork modes.
- Taint clean
- Written in Perl
- Protection against buffer overflow
- Clean process flow
- Extensibility
Net::Server is an extensible, generic Perl server engine. Net::Server combines the good properties from Net::Daemon (0.34), NetServer::Generic (1.03), and Net::FTPServer (1.0), and also from various concepts in the Apache Webserver.
Net::Server attempts to be a generic server as in Net::Daemon and NetServer::Generic. It includes with it the ability to run as an inetd process (Net::Server::INET), a single connection server (Net::Server or Net::Server::Single), a forking server (Net::Server::Fork), a preforking server which maintains a constant number of preforked children (Net::Server::PreForkSimple), or as a managed preforking server which maintains the number of children based on server load (Net::Server::PreFork). In all but the inetd type, the server provides the ability to connect to one or to multiple server ports.
Net::Server uses ideologies of Net::FTPServer in order to provide extensibility. The additional server types are made possible via "personalities" or sub classes of the Net::Server. By moving the multiple types of servers out of the main Net::Server class, the Net::Server concept is easily extended to other types (in the near future, we would like to add a "Thread" personality).
Net::Server borrows several concepts from the Apache Webserver. Net::Server uses "hooks" to allow custom servers such as SMTP, HTTP, POP3, etc. to be layered over the base Net::Server class. In addition the Net::Server::PreFork class borrows concepts of min_start_servers, max_servers, and min_waiting servers.
Net::Server::PreFork also uses the concept of an flock serialized accept when accepting on multiple ports (PreFork can choose between flock, IPC::Semaphore, and pipe to control serialization).

SJphone is a VOIP softphone that allows you to speak with any other softphone, any stand-alone IP-phone, or using ITSP with any traditional wired or mobile phone.

SJphone project supports both SIP and H.323 standards and is fully inter-operable with most major VOIP vendors and ITSP. For SJphone Profiles concept explanation please go to our support page.

Also you can try our current releases that we have not fully tested yet. They are just preview versions for new features, so we do not guarantee their stable work.

Attention!

Having SJphone installed is not enough to talk except over your local network. You have to obtain an account with any ITSP like Vonage or Free World Dialup, or install your own VoIP server.

Cego implements a relational and transactional database system with support for the SQL query language. The current release contains the most common database features for basic table manipulation and data retrieval.

Indexes, foreign keys, views, and stored procedures are also implemented. Future releases (2.0 and above) will support a multi-node database concept with log file shipping for an automatic database application failover.
