Free solar energy software for linux

Solar Visitor is a space simulator where the user flies around our Solar System in a 3D view. The program and source code are offered free, there are builds for Windows and Linux. Solar Visitor uses the Ogre graphics library. The planets and objects were created with the Blender program.
Because Solar Visitor is a 3D program, performance depends on the capabilities of the users video system.
If you wish you may build from source using available tools but be warned this is not an easy task. An addition to Ogre a compiler and IDE (on Windows) are required. The Ogre web site has installation instructions for its use. Those without c/c++ experience will find themselves jumping in the deep end.
With the release of version 0.2.x the user can view planets rendered from textures which is a vast improvement over the painted colours of 0.1.0. There is still realism to add. For instance, the orbits are engineered to showcase shadow effects and not be realistic, where eclipses are rare.
The program code is released under the GPL, the media are generated from downloadable images on the web, details of location are provided. Images remain the property of respective owners.
Enhancements:
- bugfixes
- tilted orbits

Astaro Command Center (ACC) is an application for centralized management of Astaro Security Gateways. With ACC, network administrators can easily manage and control multiple Astaro devices.
The intuitive Web-based user interface provides an effective overview that details the actual health of each device, swiftly allowing administrators to see which gateways require immediate action.
Astaro Command Center offers monitoring, inventory management, central update management, WebAdmin single-sign-on, and a world map view.
Enhancements:
- This version changes the GUI to the new look and feel of the ASG V7 style and it adds V7 support.
- It also handles the new daylight saving time dates from the Energy Savings Act in the US and Canada.
- Cluster monitoring global pattern version and UPS battery charge monitoring are now supported, and ACC can be used as an Up2Date Cache for all V7 packages.
- Besides these new features, some minor bugs were fixed.

Search::ContextGraph is a Perl module for spreading activation search engine.

SYNOPSIS

use Search::ContextGraph;

my $cg = Search::ContextGraph->new();

# first you add some documents, perhaps all at once...

my %docs = (
first => [ elephant, snake ],
second => [ camel, pony ],
third => { snake => 2, constrictor => 1 },
);

$cg->bulk_add( %docs );

# or in a loop...

foreach my $title ( keys %docs ) {
$cg->add( $title, $docs{$title} );
}

# or from a file...

my $cg = Search::ContextGraph->load_from_dir( "./myfiles" );

# you can store a graph object for later use

$cg->store( "stored.cng" );

# and retrieve it later...

my $cg = ContextGraph->retrieve( "stored.cng" );


# SEARCHING

# the easiest way

my @ranked_docs = $cg->simple_search( peanuts );


# get back both related terms and docs for more power

my ( $docs, $words ) = $cg->search(snake);


# you can use a document as your query

my ( $docs, $words ) = $cg->find_similar(First Document);


# Or you can query on a combination of things

my ( $docs, $words ) =
$cg->mixed_search( { docs => [ First Document ],
terms => [ snake, pony ]
);


# Print out result set of returned documents
foreach my $k ( sort { $docs->{$b} $docs->{$a} }
keys %{ $docs } ) {
print "Document $k had relevance ", $docs->{$k}, "n";
}

# Reload it
my $new = Search::ContextGraph->retrieve( "filename" );

Spreading activation is a neat technique for building search engines that return accurate results for a query even when there is no exact keyword match. The engine works by building a data structure called a context graph, which is a giant network of document and term nodes. All document nodes are connected to the terms that occur in that document; similarly, every term node is connected to all of the document nodes that term occurs in. We search the graph by starting at a query node and distributing a set amount of energy to its neighbor nodes. Then we recurse, diminishing the energy at each stage, until this spreading energy falls below a given threshold. Each node keeps track of accumulated energy, and this serves as our measure of relevance.

This means that documents that have many words in common will appear similar to the search engine. Likewise, words that occur together in many documents will be perceived as semantically related. Especially with larger, coherent document collections, the search engine can be quite effective at recognizing synonyms and finding useful relationships between documents. You can read a full description of the algorithm at http://www.nitle.org/papers/Contextual_Network_Graphs.pdf.

The search engine gives expanded recall (relevant results even when there is no keyword match) without incurring the kind of computational and patent issues posed by latent semantic indexing (LSI). The technique used here was originally described in a 1981 dissertation by Scott Preece.

Xplanet was inspired by Xearth, which renders an image of the earth into the X root window. All of the major planets and most satellites can be drawn, similar to the Solar System Simulator.
A number of different map projections are also supported, including azimuthal, Lambert, Mercator, Mollweide, orthographic, and rectangular.
Enhancements:
- Added the -grs_longitude option, to specify the longitude of Jupiters Great Red Spot, in System II coordinates. This assumes the Jupiter image has the center of the Great Red Spot at pixel 0 (at the left side of the image) in order to draw it at the right position.
- Added the Icosagnomonic projection, contributed by Ian Turner.
- Fixed a bug where output filenames had an extra digit in some cases.
- Added the bump_map and bump_scale options in the configuration file.
- Added the -glare option to set the size of the suns glare.
- An image map may be specified for the sun in the configuration file now. A shade value is now required for the sun (should be 100, otherwise the sun will have a night side!)
- Added the -arc_spacing option to set the default angular distance between great arc points. It used to be 0.1 degree, so arcs smaller than this wouldnt get drawn.
- Fixed a bug where markers were not aligned properly when using align = "above" or "below".
- Added warnings if options are specified in the [default] section of the configuration file that probably shouldnt be there.

The purpose of Planets 3D is to show a simulation of our solar system. The focus lies on a nice graphic (3D OpenGL) and the possibility to modify the objects of the solar system to see what happens.
This program is written on Linux using C++. In theory it should be portable to windows, because Ive used only plattform independent libraries. Anyone who tries to port it please contact me even if unsuccessful, perhaps I can help overcome arising errors.
By now there is included a small program which converts different coordinate systems into each other. It is called Astroconvert.
Main features:
- simulate the development of the solar system based on calculations of the gravity power
- take screenshots
- load and save solar systems
- modify solarsystem
- switch between different cameras to view the solar system (e.g. look through a shuttle window)

scanlogd project is a system daemon which attempts to log all portscans of a host to the syslog, in a secure fashion.

This release of scanlogd can be built with support for one of several packet capture interfaces. In addition to the raw socket interface on Linux (which does not require any libraries), scanlogd is now aware of libnids and libpcap.

The use of libpcap alone is discouraged. If youre on a system other than Linux and/or want to monitor the traffic of an entire network at once, you should be using libnids in order to handle fragmented IP packets.

Bob the Butcher project is a distributed password cracker package.
This is ALPHA software, full of bugs, some of them being likely to be security holes. Besides, there is no client authentification, so anybody could impersonate a client and alter your search results.
Only use it on a trusted network!
Main features:
- Ciphers near source compatibility with John the Ripper. Bob the Butcher benefits from the fast algorithms that have been develloped for John:
Traditionnal DES Solar Designer
BSDI DES [BROKEN] Solar Designer
FreeBSD MD5 [BROKEN] Solar Designer
Windows NTLM (MD4)
MMX/SSE2 bartavelle
Windows Cache (mscash) bartavelle
Raw MD5 (hex-encoded) bartavelle
Raw SHA1 (hex-encoded) bartavelle
MySQL passwords Noah Williamsson
Netscape LDAP SHA Sun-Zero
Netscape LDAP SHA
MMX/SSE2 Bartavelle
Lotus Domino Jeff Fay
Oracle Passwords Bartavelle
- Password cracking speed scales linearly with the number of cracking clients.
- Central server that can handles several jobs, supporting different priorities (in the future.
- Smart keyspace distribution when several jobs are using the same algorithm (not for now).
Usage:
Build instructions
Only works on pentium or later!
./configure --enable-debug
make
cd bob_client
./bob_client -b
If it segfaults, try again with:
./configure --enable-debug --disable-sse2
bob_server
Just run ./bob_server -k SECRET_KEY
bob_admin
Use it to add jobs and check status. For now only he following commands work:
newjob : add a new job
status : gives general status
jobinf : give detailled status
Dont forget to use the -k switch for PSK.
bob_client Put this one on as many computers as possible, and just run:
./bob_client -d -k SECRET_KEY server_host_name
Enhancements:
- Bugfixes in cyphers, support for Solaris, and a prototype Python server.
