Graph::Weighted is an abstract, weighted graph implementation.

SYNOPSIS

use Graph::Weighted;

$g = Graph::Weighted->new(
data => [
[ 0, 1, 2, 0, 0 ], # A vertex with two edges.
[ 1, 0, 3, 0, 0 ], # "
[ 2, 3, 0, 0, 0 ], # "
[ 0, 0, 1, 0, 0 ], # A vertex with one edge.
[ 0, 0, 0, 0, 0 ] # A vertex with no edges.
]
);

$g = Graph::Weighted->new(
data => {
weight => {
a => { b => 1, c => 2 }, # A vertex with two edges.
b => { a => 1, c => 3 }, # "
c => { a => 2, b => 3 }, # "
d => { c => 1 }, # A vertex with one edge.
e => {} # A vertex with no edges.
}
foo => [
[ 1, 2, 3 ],
[ 4, 5, 6 ],
[ 7, 8, 9 ]
],
}
);

$g = Graph::Weighted->new(
data => $Math_Matrix_object,
retrieve_as => ARRAY,
);

$data = $g->weight_data;

$w = $g->graph_weight;

$w = $g->vertex_weight($v1);
$w = $g->vertex_weight($v1, $w + 1);

$w = $g->edge_weight($v1, $v2);
$w = $g->edge_weight($v1, $v2, $w + 1);

$vertices = $g->heaviest_vertices;
$vertices = $g->lightest_vertices;

$w = $g->max_weight; # Weight of the largest vertices.
$w = $g->min_weight; # Weight of the smallest vertices.

# Call the weight methods of the inherited Graph module.
$x = $g->MST_Kruskal;
$x = $g->APSP_Floyd_Warshall;
$x = $g->MST_Prim($p);

SmokePing is a delux latency measurement tool. SmokePing project can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm datastore and to draw pretty graphs, giving up to the minute information on the state of each network connection.
SmokePing uses latency measurement plugins for seamless extendability.
SmokePing comes with a smart alarm system. Apart from simple threshold alarms, you have the option of defining latency or loss patterns and use them to trigger alarms.
This allows you to define a pattern which would generate a single alarm when the loss goes from below 1% to over 20% and stays over 20% for more than 10 minutes. The advantage of this approach is the virtual elimination of duplicate alarms which you would get with a simple threshold based system.
Alarms can be sent to a mail address or a pager and if you want you can also start an external script to handle the alarms.
Complex Alarms can be written as plug-ins.
SmokePing can also deal with machines who frequently change their IP address by allowing the remote host to call SmokePings attention to its new IP address. In such a setup SmokePing monitors also for how long the remote system could keep its IP address.
To ensure that it is not suddenly monitoring the wrong host, SmokePing further tries to fingerprint each of its Dynamic IP targets via SNMP.
SmokePing is written in Perl. It consists of a daemon process responsible for data collection and a CGI script presenting the data on the web.
The CGI script uses SpeedyCGI to achieve mod_perl like performance without the need to deploy mod_perl on your web server. SmokePing sports a plug-in architecture to easily add new latency measurement capabilities to SmokePing. SmokePing works happily on all Unix platforms.
Enhancements:
- The scoreboard has a list of hottest targets.
- Echoping V6 compatibility.
- Mail templates.
- A failover server for alert email messages.
- Many new plugins.
- Several bugfixes.

Main features:
- fast
- text-based sequence diagram
- call from command line.

lwIP is a light-weight implementation of the TCP/IP protocol suite that was originally written by Adam Dunkels of the Swedish Institute of Computer Science but now is being actively developed by a team of developers distributed world-wide headed by Leon Woestenberg.
Since its release, lwIP very interesting and and today is being used in many commercial products. lwIP has been ported to several platforms and operating systems and can be run either with or without an underlying OS.
The focus of the lwIP TCP/IP implementation is to reduce the RAM usage while still having a full scale TCP. This makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM.
Main features:
- IP (Internet Protocol) including packet forwarding over multiple network interfaces
- ICMP (Internet Control Message Protocol) for network maintenance and debugging
- UDP (User Datagram Protocol) for datagram data
- TCP (Transmission Control Protocol) with congestion control, RTT estimation and fast recovery/fast retransmit
- Specialized no-copy API for enhanced performance
- Optional Berkeley socket API

Orpheus is a light-weight text mode menu- and window-driven audio player application for CDs, MP3, Vorbis OGG and internet stream broadcasts.
Main features:
Text mode user interface
- Based on the ncurses library
- Provides windows, menus and dialogs
- Configurable color schemes
- Configuration is done with dialogs
Player
- Supports MP3 (through mpg123), OGG (with ogg123), CD tracks and internet broadcasts
- Saves and loads playlists
- Provides quick access to recent lists played
- Can combine CD, MP3 and OGG tracks in the same playlist
- Edit MP3 and OGG ID tags feature
- "Repeat track", "Repeat play list" and "Random" play modes
- Play list sorting and search options
- Auto-generated currently_playing file which makes it possible to easily find out from other applications what is playing now
- Internal mixer controller
- Command line interface for controlling an already running instance of the program
Network
- CDDB information retrieval for CDs
- HTTP proxy support
- Auto-load of the Internet radio presets directory from the network
Enhancements:
- This release converts from utf-8 for OGG tracks and supports Internet radio.
- Broadcasts can now be added to the playlist along with the other items.
- For the initial stations directory, the presets directory from the screamer-radio project is used.

Kemistry is a collection of chemical applications for the K Desktop Environment (release 3.x).

Originally the applications were distributed in a single source package, but currently every application is distributed in a standalone package. The available applications are

* KMolCalc - molecular weight and elemental composition calculator
* KemBabel - a file conversion program based on Open Babel

subPersistence is an abstract, light-weight yet flexible framework for working with O/R persistence mappers. It provides for independence of a specific O/R mapper such as Hibernate or Castor.
While you can use Hibernate or Castor (or other O/R mappers) directly, coupling your application too tightly to those can be a bad thing. subPersistence makes it easy to switch underlying O/R mappers, thereby decoupling the application layer from those.
It abstracts away differences between the mappers, while still making it possible to use their specific features if needed.
Enhancements:
- This version updates to Java 5 features such as Generics and is the first version to require Hibernate 3.
