Free message software for linux

GaimGajimNowPlaying is an Amarok script add at the end of your status message in Gajim and Gaim what you are playing now.

Off-the-Record Messaging is a Pidgin plugin that allows you to have private conversations over instant messaging by providing:
Encryption
No one else can read your instant messages.
Authentication
You are assured the correspondent is who you think it is.
Deniability
The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured
the messages he sees are authentic and unmodified.
Perfect forward secrecy
If you lose control of your private keys, no previous conversation is compromised.
Enhancements:
- Translations for English, Dutch, Spanish, French, Slovak
- Added option to not log OTR conversations
- Large messages are now fragmented transparently instead of failing
- Removed "view secure session id" and "verify fingerprint" options from the OTR button menu. Added "authenticate buddy" option in its place. This new option allows you to authenticate your buddies by entering some secret that only the two of you know, rather than by using a long user-unfriendly sequence of hex characters. [The old "verify fingerprint" dialog is still available via an "Advanced..." button from the new "authenticate buddy" dialog.]

Genoa Active Message MAchine is a low-latency, high-throughput driver wrapper for the Linux kernel, using Active Ports (a version of Active Messages).
Genoa Active Message MAchine runs parallel to the IP stack and is designed for LANs only.
Main features:
- A low latency, high throughput communication system for clusters of PCs
- Supports both single and dual CPU processing nodes (Intel IA-32 or x86_64)
- Runs on Gigabit Ethernet
- SPMD parallel processing with message passing
- Can run IP traffic when not in use
- Good programmability thanks to fairly high abstraction level
- Reliable thanks to mechanisms for retransmission of missing packets
- Implemented as a network device driver for Linux 2.6, and released under GNU GPL
Network Of Workstations (NOWs) and clusters of PCs interconnected by modern, industry-standard LAN fabrics (Gigabit Ethernet, Myrinet, SCI) and running the Linux operating system, have became an attractive and cost-effective architecture for parallel and distributed applications. The usual drawback of a standard PC cluster is the poor performance of the support to inter-process communication over the interconnect. Current implementations of industry-standard communication primitives, APIs, and protocols, usually show high communication latencies and low communication throughput.
We have developed a system for inter-process communication, called the Genoa Active Message MAchine (GAMMA). GAMMA runs on Linux clusters of PCs with Intel IA-32 processors (Intel Pentium, AMD K6, and superior models), or x86_64 processors (AMD Athlon64, AMD Opteron, Intel EMT-64), networked by a Gigabit Ethernet.
The core of GAMMA is a custom Linux network device driver, which operates the Network Interface Card (NIC). The GAMMA driver delivers low latency, high throughput communication services based on Active Ports, a mechanism derived from Active Messages. Both point-to-point and broadcast communications are provided. Broadcast communication exploits the Ethernet broadcast directly.
The GAMMA driver is able to manage standard IP traffic as long as no parallel job is running. Therefore, all IP services are up and running whenever the cluster is not in use by any parallel job.
The communication mechanisms implemented in the GAMMA driver are made available to application writers through the GAMMA user library. The GAMMA library provides support to application launch, process grouping, point-to-point/broadcast communications based on the Active Ports mechanisms, and some collective routines (barrier synchronization, and broadcast).
GAMMA provides two levels of QoS. The lower one, corresponding to the fastest communications, is a best-effort service. With this service, network congestion and ``hot spots may cause the receiver NIC or even the LAN switch to loose packets by overrun. The other QoS level provides flow-controlled communication, ensuring reliability up to hardware faults, at a negligible performance penalty.
Installing the GAMMA driver requires only two small and marginal patches to the original Linux kernel. The Linux kernel extended by the GAMMA driver must be installed on each PC in the cluster.
A porting of MPI atop GAMMA is available, called MPI/GAMMA.

AmarokPidgin is a plugin for Amarok that updates your Pidgin status message with what you are currently listening too.
If you want to update your Gaim status message, look from the AmarokGaim package.

python-dime project provides a way to parse and generate DIME messages.

Direct Internet Message Encapsulation (DIME) is a binary message format that can be used to encapsulate multiple payloads into a single message.

Mail::Message::Field contains one line of a message header.

INHERITANCE

Mail::Message::Field
is a Mail::Reporter

Mail::Message::Field is extended by
Mail::Message::Field::Fast
Mail::Message::Field::Flex
Mail::Message::Field::Full

SYNOPSIS

my $field = Mail::Message::Field->new(From => fish@tux.aq);
print $field->name;
print $field->body;
print $field->comment;
print $field->content; # body & comment
$field->print(*OUT);
print $field->string;
print "$fieldn";
print $field->attribute(charset) || us-ascii;

This implementation follows the guidelines of rfc2822 as close as possible, and may there produce a different output than implementations based on the obsolete rfc822. However, the old output will still be accepted.

These objects each store one header line, and facilitates access routines to the information hidden in it. Also, you may want to have a look at the added methods of a message:

my @from = $message->from;
my $sender = $message->sender;
my $subject = $message->subject;
my $msgid = $message->messageId;

my @to = $message->to;
my @cc = $message->cc;
my @bcc = $message->bcc;
my @dest = $message->destinations;

my $other = $message->get(Reply-To);

Net::Oscar project is a pure Perl implementation of the OSCAR protocol used by ICQ and AIM instant message clients.
