Free simplified software for linux

simpleJ emulates a simplified computer on your PC: a retro-style video game console that lets you understand how a computer works and write your own video game programs. The first microcomputers were quite simple.

They had a few kilobytes of memory and couldnt run large programs. Many didnt even have an operating system.

Yet they had something valuable: understanding everything about their hardware and software was easy. simpleJ aims to make this possible while running on modern PC hardware.

Samizdat is a generic RDF-based engine for building collaboration and open publishing Web sites.
It provides users with the means to cooperate and coordinate on all kinds of activities, including media activism, resource sharing, education and research, advocacy, and so on. The project intends to promote values of freedom, openness, equality, and cooperation.
Enhancements:
- This version incorporates two years worth of real-world deployment.
- Apart from ubiquitous message translations management and RSS syndication, many old tools were made more flexible and easier to use.
- The focus management interface is simplified, and the front page packs more information into a better layout and allows you to include static headers and footers.
- Even more changes are under the hood: multi-layer caching, gzip and ETag, audio and video uploads, BitTorrent links, HTML and CSS filtering, flexible access control, new moderation features, new languages and themes, simplified installation, and more.

SELinux Policy Editor (seedit) is a tool to make SELinux policies easy to apply. SELinux Policy Editor was originally developed by Hitachi Software.

SELinux Policy Editor is composed of Simplified Policy and tools. Simplified Policy is a policy described by Simplified Policy Description Language (SPDL) which hides the details of SELinux configurations by using name-based configration and reducing the number of permissions.

SELinux Policy Editor includes a GUI to generate SPDL so adminstrators do not have to remember syntax of the language. There are also command line tools in the package.

Following is example policy for Apache using SPDL.
domain httpd_t;
program /usr/sbin/httpd;
allow /var/www/** r,s;
allownet -protocol tcp -port 80 server;

As you see from the example type is not used. You can use file names and port numbers for configuration.

You can try SELinux Policy Editor on Fedora Core 5. It will not affect existing SELinux policies so it is possible to revert to the default SELinux easily.

XML::Writer is a Perl extension for writing XML documents.

SYNOPSIS

use XML::Writer;
use IO::File;

my $output = new IO::File(">output.xml");

my $writer = new XML::Writer(OUTPUT => $output);
$writer->startTag("greeting",
"class" => "simple");
$writer->characters("Hello, world!");
$writer->endTag("greeting");
$writer->end();
$output->close();

XML::Writer is a helper module for Perl programs that write an XML document. The module handles all escaping for attribute values and character data and constructs different types of markup, such as tags, comments, and processing instructions.

By default, the module performs several well-formedness checks to catch errors during output. This behaviour can be extremely useful during development and debugging, but it can be turned off for production-grade code.

The module can operate either in regular mode in or Namespace processing mode. In Namespace mode, the module will generate Namespace Declarations itself, and will perform additional checks on the output.

Additional support is available for a simplified data mode with no mixed content: newlines are automatically inserted around elements and elements can optionally be indented based as their nesting level.

libStreamedXML is a parser for Streamed XML, a simplified subset of XML initially developed for networked embedded applications.
Streamed XML was designed to be simpler and more robust than XML while still keeping the overall structure of such a document.
libStreamedXML library is a C++ parser providing an event-based interface (much like sax).
Enhancements:
- libCStreamedXML and a test program were added.
- libCStreamedXML is a smaller and simpler implementation of a Streamed XML parser written in C.

Ever lost an hour worth of writing an email due to a crashing browser? LiveSaver is a save-as-you-write mechanism for your browser written in Javascript.
It saves form input over browser and operation system crashes, power failures, and session timeouts. It is easy to add to any existing Web site. LiveSaver is particularly useful for blog software, Web mail systems, or any Web site that deals with user input.
Enhancements:
- A MediaWiki Extension was added that allows you to integrate LiveSaver in every MediaWiki installation very easily.
- Self-configuration was added to decrease installation issues.
- The API was simplified.
- Operability was tested with a suite of the latest browsers on Mac OS X and Windows.
