Free subscribe now software for linux

MUSCLE is a somewhat scalable, robust, cross-platform client-server messaging system for dynamic distributed applications that runs under any POSIX-compliant operating system.
MUSCLE has been developed, used, and refined as the networking component of BeShare, CueStation, CueConsole, and various other audio control applications at Level Control Systems for over four years.
Main features:
- Use BMessage-like muscle::Messages under any operating system.
- Send flattened muscle::Messages from one computer to another over TCP streams, eliminating unnecessary compatibility and protocol-versioning hassles.
- Run a "muscled server" on a central machine, and write (or download) client programs to log in to the server and communicate through it. Once logged in, client programs can discover who else is logged in, send muscle::Messages to other clients, and store muscle::Messages in the servers RAM for other clients to download later. Clients can also "subscribe" to selected data on the server, and be automatically notified whenever it changes. Unicast-style, multicast-style, and broadcast-style Message routing are all supported via an intelligent hierarchical pattern-matching routing mechanism. Writing multiplayer games, IRC style chat applications, SETI style distributed calculation apps, or any other type of distributed software is made easy because MUSCLE handles all the dirty work for you!
- Customize the included "muscled server" by defining your own session logic or message-streaming protocol. (Note that this is only necessary for certain specialized applications--the standard server provides sufficient functionality for most things)
- Write your client code in C++, Java, or Python. Single-threaded and multi-threaded messaging APIs are provided for all three languages.
- Or just use the included message, string, dataIO, hashtable, dequeue, string-tokenizer, reference-count, regular expression and pattern matching parser, and object-pool code by themselves, as handy cross-platform utility classes. All source code is included, and you are free to use and abuse it any way you wish.
- See the Beginners Guide for a more detailed description of the system and its capabilites.
Enhancements:
- This release includes various minor bugfixes to the Java and C++ code, as well as a few minor optimizations.

libpubsub provides everything to setup a simple publish/subscribe environment.
If you are looking for a way to let several processes (not necessarily on the same host) exchange information with each other in a very easy (read at the moment: simple) way, libpubsub may interest you!
The main target is the usage in C++ applications. The package includes a tool to let even shell scripts get in touch with pubsub.
Enhancements:
- the client is able to read the message broker address from the environment variable PUBSUB_BROKER
- added conversion routines between binary data and hexadecimal strings
- added support for very large messages over TCP
- several minor bugfixes and cosmetic changes
- embedded users guide into doxygen generated docs

News::Archive is a Usenet news archiving package for downloading and later accessing news articles in bulk.

It can load articles laid out in INN format, retrieve them from a running news server, or just take articles one-by-one. News::Archive module is compatible with News::Web and Net::NNTP::Server, so the articles can be shared either via the Web or via NNTP.

SYNOPSIS

use News::Archive;
my $archive = new News::Archive
( basedir => /home/tskirvin/kiboze );

# Get a news article
my $article = News::Article->new(*STDIN);
my $msgid = article->header(message-id);

die "Already processed $msgidn"
if ($archive->article( $messageid ));

# Get the list of groups were supposed to be saving the article into
my @groups = split(s*,s*, $article->header(newsgroups) );
map { s/s+//g } @groups;

# Make sure were subscribed to these groups
foreach (@groups) { $archive->subscribe($_) }

# Actually save the article.
my $ret = $archive->save_article(
[ @{$article->rawheaders}, , @{$article->body} ], @groups );
$ret ? print "Accepted article $messageidn"
: print "Couldnt save article $messageidn";

News::Archive keeps several files to keep track of its archives:

active file

Keeps track of all newsgroups we are "subscribed" to and all of the information that changes regularly - the number of articles we have archived, the current first and last article numbers, etc.

Watched over with News::Active.

history database

A simple database keeping track of articles by Message-ID. Makes access by ID easy, and ensures that we dont save the same article twice. The database chosen to maintain these is user-determined.

newsgroup file

Keeps track of more static information about the newsgroups we are subscribed to - descriptions, creation dates, etc.

Watched over with News::GroupInfo.

archive directory

Directory structure of all articles, with each article saved as a single textfile within a directory structure laid out at one section of the group name per directory, such as "rec/games/mecha". Crossposts are hardlinked to other directory structures.

Articles are actually divided into sub-directories containing up to 500 articles, to avoid Unix directory size performance limitations. Individual files are thus stored in a file such as "rec/games/mecha/1.500/1".

Each newsgroup also contains overview information, watched over with
News::Overview. This overview file goes in the top of the structure,
such as "rec/games/mecha/.overview".

You may note that these files are very similar to how INN does its work. This is intentional - this package is meant to act in many ways like a lighter-weight INN.

Usage:

Global Variables

The following variables are set within News::Archive, and are global throughout all invocations.

$News::Active::DEBUG
Default value for "debug()" in new objects.

$News::Active::HOSTNAME
Default value for "hostname()" in new objects. Obtained using
"Sys::Hostname::hostname()".

$News::Active::HASH
The number of articles to keep in each directory. Default is 500;
change this at your own peril, since things may get screwed up later
if you change it after archiving any articles!

The purpose of SingleSub is to a provide a set of tools to make it easier to subscribe to RSS feeds.

It consists of one Perl script and a set of XSLT templates, which provide RSS, HTML and Javascript tools used to subscribe to RSS feeds without restricting them to a specific aggregator.

Instead, a dynamic list of aggregators is provided for the user to choose from. This list of RSS aggregators and how to subscribe to them is provided via several XML formats, so other tool developers can use them as well.

amaroK Now-Webing starts a webserver at an configurable port (Standard is 8080) which display the current song and artist.

Works great for parsing and displaying data on a webserver.

Avis client library is a Java API for clients accessing Elvin event routers, including the open source Avis event router and the commercial Mantara Elvin product.
Avis is an event router service compatible with the commercial Elvin implementation developed by Mantara Software. Avis provides a fast, general-purpose publish/subscribe message bus.
Elvin event routers alllow arbitrary messages, known as notifications, to be exchanged via a publish/subscribe model. Elvin clients subscribe to messages published by other clients using expressions that match messages by their content.
The content-based routing approach used in Elvin routers differs from many other message bus systems that operate by selecting messages published on pre-defined channels, and has the advantage of promoting a much higher level of decoupling between producers and consumers of events.
The name "Avis" derives from the French word avis, meaning advice or notification.
Enhancements:
- This release marks a stable baseline for the Java client API.
- The core set of features required for an Elvin client library are now implemented and stable, including subscription, notification, security, close event notification, liveness checking, and router connection option support.
