Free simple directmedia software for linux

Simple DirectMedia Layer project is a library that gives portable low-level access for multimedia applications.
Simple DirectMedia Layer is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. It is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power."
SDL supports Linux, Windows, Windows CE, BeOS, MacOS, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. The code contains support for AmigaOS, Dreamcast, Atari, AIX, OSF/Tru64, RISC OS, SymbianOS, and OS/2, but these are not officially supported.
SDL is written in C, but works with C++ natively, and has bindings to several other languages, including Ada, C#, Eiffel, Erlang, Euphoria, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP, Pike, Pliant, Python, Ruby, and Smalltalk.
SDL is distributed under GNU LGPL version 2. This license allows you to use SDL freely in commercial programs as long as you link with the dynamic library.
Enhancements:
- Dynamic X11 loading is only enabled with gcc 4 supporting -fvisibility=hidden. This fixes crashes related to symbol collisions, and allows building on Solaris and IRIX.
- Fixed building SDL with Xinerama disabled.
- Fixed DRI OpenGL library loading, using RTLD_GLOBAL in dlopen().
- Added pkgconfig configuration support.

Simple Firewall is a easy tool for administration users and access control. This tool is made for Linux. Using iptables for packet filtering Write in perl Save rules with xml. That can be run in bash shell and web interface via webmin.

Simple Aggregator is a Web-based news aggregator. It retrieves feeds using Mark Pilgrims Ultra Liberal feed Parser, making full use of its advanced features. It stores the feeds in a MySQL database, and displays news via a PHP frontend.
Enhancements:
- the backend is now ready for categories (planned for the next release)
- the feedsloader script now uses threads for much better performance
- the feedsloader script now periodically cleans up read entries
- the feedsloader script now traps feed encoding errors
- added OPML import and export for feeds
- moved CSS style sheets to a common external file
- small fixes mainly to the user menu links

Simple Equation makes it simple to put equations on the Web. Simple Equation project does not bother the user with the layout of the equation; it just displays it. The focus is on being simple to use.

One of the biggest obstacles to using mathematical expressions on the web is that the user currently needs to worry about layout. Web users should not have to learn a layout engine.

The class is built as a recursive parser. It is pretty easy to add operations to the parser, but it will not scale to a huge set of operations. That is OK, we want to keep things simple. At some point a layout engine may be required for a complexity level. This is not a layout engine.

Currently, only graphical output is generated, but it is hoped that MathML output can be generated automatically if the browser supports it instead of the graphic.

Simple Backup is a shell script to create basic backups using tar, grep, sed, and bash.

Simple Backup works by using a file that contains the folders to be backed up and a file that contains expressions to exclude certain folders/files.

Usage: backup.sh < backuplist > < excludelist >

Free to use at your own risk. The author cant be held responsible for any side effects

XML::Simple::DTDReader is a simple XML file reading based on their DTDs.

SYNOPSIS

use XML::Simple::DTDReader;

my $ref = XMLin("data.xml");
Or the object oriented way:
require XML::Simple::DTDReader;

my $xsd = XML::Simple::DTDReader->new;
my $ref = $xsd->XMLin("data.xml");

XML::Simple::DTDReader aims to be a XML::Simple drop-in replacement, but with several aspects of the module controlled by the XMLs DTD. Specifically, array folding and array forcing are inferred from the DTD.

Currently, only XMLin is supported; support for XMLout is planned for later releases.

Tree::Simple::View::HTML is a Perl class for viewing Tree::Simple hierarchies in HTML.

SYNOPSIS

use Tree::Simple::View::HTML;

## a simple example
# use the defaults (an unordered list with no CSS)
my $tree_view = Tree::Simple::View::HTML->new($tree);

## more complex examples

# use the CSS properties
my $tree_view = Tree::Simple::View::HTML->new($tree => (
list_type => "ordered",
list_css => "list-style: circle;",
list_item_css => "font-family: courier;",
expanded_item_css => "font-family: courier; font-weight: bold",
));

# use the CSS classes
my $tree_view = Tree::Simple::View::HTML->new($tree => (
list_css_class => "myListClass",
list_item_css_class => "myListItemClass",
expanded_item_css_class => "myExpandedListItemClass",
));

# mix the CSS properties and CSS classes
my $tree_view = Tree::Simple::View::HTML->new($tree => (
list_css => "list-style: circle;",
list_item_css => "font-family: courier;",
expanded_item_css_class => "myExpandedListItemClass",
node_formatter => sub {
my ($tree) = @_;
return "" . $tree->getNodeValue()->description() . "";
}
));


# print out the tree fully expanded
print $tree_view->expandAll();

# print out the tree expanded along a given path (see below for details)
print $tree_view->expandPath("Root", "Child", "GrandChild");
