Free communications jobs 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.

Computation Job Management (jobman in short) is a program that calls executables according to a given program flow. Each executable is run in a separate process. It is useful when a project needs to carry out a series of calculations that are performed by software written in different languages or supplied by third parties, but invoking individual programs manually is error prone and hard to manage.
The various individual programs dont communicate with each other except via persistent storage. This is especially the case for some scientific computing, quantitative finance, and prototyped programming.
Enhancements:
- A job can output a status string indicating to skip other sibling jobs.
- Fixed a number of bugs.
- Mark the program in beta status as it has been used to manage jobs completed in days.

Buni Meldware Communication Suite (MCS) is a platform-independent groupware package consisting of:
- Meldware Mail
- Meldware Calendar
- Meldware Webmail
- Meldware Secure Administration System
Together the package provides support for thousands of users concurrently to send and receive email and to schedule meetings. MCS uniquely allows you to store all messages and scheduling events in nearly any database and runs on nearly all popular software and hardware platforms.
MCS commitment to platform and database agnosticism aims to meet increasing business requirements to maximize ease and flexibility of managing and accessing data as well as putting a premium on interoperability.
Additionally, while the scheduling and calendaring services can be installed separately, the integrated feature set provides both a distinctive and powerful experience to both users and server-side Mail Based Applications and Collaboration Based Application Services.
The MCS platform provides security integration using LDAP sources including Microsoft Active Directory as well as flat-file and database sources.
Additionally, extensible security allows custom authentication/authorization sources.
Enhancements:
- This is the first milestone release with WCAP, freebusy for webmail, and mature IMAP all together.
- It has undergone extensive hardening, dogfooding, and QA testing.
- The WCAP protocol for calendaring now works well for Thunderbird and Lightning 0.3.
- Webmail calendaring was greatly improved.
- The abillity to download attachments has been added to the webmail interface.
- Numerous performance improvements have been made in SMTP, IMAP, and MIME parsing since 1.0-M7.

Qemulator provides an easy and fast to use image and device management, a "My machines" list and interactive job control.

It comes with a list of all running jobs from where you can open the contol panel for each job and performing on demand action. Full interaction for mounted volumes, usb devices, keyboard and mouse interaction, screenshots, wave capture and save/restore machine state and open vnc viewer is provided.

The project is still under development. Current version should run stable on most Linux machines providing allmost all functions of qemu, but there are still some works to do.

Anyone who has spent enough time in Linux probably believes that you can never have enough control.

LPQ Control PHP script is a tool that parses the output of the lpq command and provides a web interface that allows you to remove print jobs from a printer.

You need to make sure that Apache can execute the lprm command. For a
default Apache installation, you will need to add the following line to
your /etc/sudoers file:

apache ALL=(root) NOPASSWD:/usr/bin/lprm

This allows the PHP program to remove *ANY* specified print job.

mpiBLAST is an MPI based parallel implementation of NCBI BLAST. The project consists of a pair of programs that replace formatdb and blastall with versions that execute BLAST jobs in parallel on a cluster of computers with MPI installed. There are two primary advantages to using mpiBLAST versus traditional BLAST.

First, mpiBLAST splits the database across each node in the cluster. Because each nodes segment of the database is smaller it can usually reside in the buffer-cache, yielding a significant speedup due to the elimination of disk I/O. Second, it allows BLAST users to take advantage of efficient, low-cost Beowulf clusters because interprocessor communication demands are low.

mpiBLAST achieves super-linear speedup in situations where the database is too large to fit into RAM, and near linear speedup in other situations. It does not require a dedicated cluster.

cpulimit is a simple program that attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you dont want they eat too much cpu.

cpulimit project does not act on the nice value or other scheduling priority stuff, but on the real cpu usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.
