mod_access_referer is a module for the Apache HTTP Server that provides access control based on "Referer" HTTP header content.

Why is mod_access_referer useful?
Basically, it allow or deny the access based on what page is shown in the Web browser, which means that if you publish a document (picture, chart or other) in your site, the people will have to visit your Web site to access it, and no one will be able to link just the document.

Motivation:

There are many organizations that publish valuable files (pictures, charts, and other documents) in their Web sites. Those organizations want to make public those files, but at the same time they want the people having visiting their Web sites in order to get those files (example, in order to get revenue from sell banners which are shown at the Web site).

But, there are situations where the files are linked from other Web sites, other than the organization owns. In such situations, the organization is loosing twice: one because the people dont visit the organizations Web site to get the files, and another because the organization still pay the necessary bandwidth to get the files.

Most browsers today send the "Referer" HTTP header in each request that comes from another Web page. This can be used to track from where the resources are linked, but it can be used to allow or deny the access to such resources if the "Referer" is not a page from the organizations Web site.

mod_access_referer is an Apache module that understand the "Referer" HTTP header, and grant or deny access based on the Web page that refered the file.
The "Referer" HTTP header is sent by the browser to the server, and it contains the URL of the resource from where the URL of the asked resource was obtained. The document "Hypertext Transfer Protocol -- HTTP/1.1" RFC 2616 gives the following explanation:

"The Referer[sic] request-header field allows the client to specify, for the servers benefit, the address (URI) of the resource from which the Request-URI was obtained (the "referrer", although the header field is misspelled.) The Referer request-header allows a server to generate lists of back-links to resources for interest, logging, optimized caching, etc. It also allows obsolete or mistyped links to be traced for maintenance. The Referer field MUST NOT be sent if the Request-URI was obtained from a source that does not have its own URI, such as input from the user keyboard."

The QDS library allows Qt applications to access features provided in common desktop APIs in a portable way, without requiring dependencies on any desktop platform library.
This is especially useful for applications targeting the Unix desktops, because Qt/X11 is very generic and only provides features it can implement on all sub platforms. All library code is licenced under 2-clause BSD licence.
Service implementations are loaded from plugins which link to the respective desktop libraries. The plugin to use can be specified on the applications commandline, in the QDS configuration file or QDS can try to autodetect the currently running platform.
Enhancements:
- Autodetection to use GNOME plugin in case GNOME_DESKTOP_SESSION_ID is set
- Replaced the primitive example application with a simple but network aware text editor application
- Support for wildcards in mailcap entries

ID3V2.3 library is a library written in C to provide read and write access to ID3 tags.

ID3V2.3 library is designed to be very easy to use, and is meant to be compiled directly into your project. You can only access the most commonly used tag fields.

The source code is easy to read and well documented.

Example:

#include "genre.h"
#include "lib_id3v1.h"

main()
{
id3Tag tag;

strcpy (tag.artist, "Myartist");
strcpy (tag.album, "Myalbum");
strcpy (tag.title, "Mysong");
strcpy (tag.track, "12");
strcpy (tag.year, "2002");
strcpy (tag.comment, "Mycomment");
strcpy (tag.genre, "Mygenre");

set_id3v2tag(&tag, "/home/sam/myfile.mp3");
}

If you need more info, look into the header file, its really simple.

WebService::Google::Sets is a Perl access to Google Labs Sets site.

SYNOPSIS

use WebService::Google::Sets;

my @os_list = qw(Linux Windows Solaris);
my $expanded_os_list = get_gset(@os_list);

# check something came back
die "No results returned from server" unless $expanded_os_list;

foreach my $element (@$expanded_os_list) {
print $element, "n";
}

WebService::Google::Sets provides function based access to the Sets service hosted at Google Labs.

The Sets service attempts to expand the values you provide. The example provided in the SYNOPSIS would return an array that included "Windows NT", "HPUX" and "AIX" as values in addition to those supplied.

LibQtPod provides access to the contents of an Apple iPod. The code was formerly part of the kio ipodslave, but is now a separate Qt-based library.
LibQtPod library features reading and writing of the iTunesDB music database and provides access to hardware specific information like disc space statistics.
Main features:
- Reading/Writing the iTunesDB Music database
- access to hardware specific information like disc space statistics
Bugs/noticable problems:
- please report any problem you encounter with the software to the sourceforge project page at http://sourceforge.net/projects/kpod
- Since podcasts and smart playlists are unsupported at the moment youll lose them when synchronizing the database.
Installation:
1. `cd to the directory containing the packages source code and type `qmake to configure the package for your system and to create the Makefiles. qmake can be found in the bin directory of your Qt installation. You may have to add the directory to your PATH before running it.
2. Type `make to compile the package.
3. Type `make install to install the programs and any data files and documentation.
4. You can remove the program binaries and object files from the source code directory by typing `make clean.

- This version contains lots of fixes and code cleanups.
- On the functional side, this release adds playlist sorting by setting one of the predefined sort order criteria and a new track(list) search implementation with user definable predicates.
- Browsing while on the go was speeded up by writing out type 52 MHODs; this may also result in smaller gaps between songs.
Whats New in 0.3 RC1 Development Release:
- Documentation fixes
- added trackNumber to ITunesDB::findTrack and TrackPredicated::ByFullInfo
- changed ITunesDB::findFirstTrackBy() and ::getTracksBy() to use a reference instead of a pointer to the predicate

OpenLink Virtuoso is a Virtual Database product that provides transparent real-time access to disparate data sources (ODBC, JDBC, XML, and Web Services), and transparent integration of disparate application logic (e.g. Mono ECMA-CLI and J2EE integration). OpenLink Virtuoso Universal Servers broad protocol support enables it to offer Web, File, and SQL database server functionality alongside native XML storage, and Web services platform functionality as part of a cohesive single server solution.
Virtuoso is at the core a high performance object-relational SQL database. As a database, it provides transactions, a smart SQL compiler, powerful stored procedure language with optional Java and .Net server side hosting, hot backup, SQL 99 and more. It has all major data access interfaces, as in ODBC, JDBC, ADO .Net and OLE/DB.
Virtuoso has a built-in web server which can serve dynamic web pages written in Virtuosos web page language as well as PHP, ASP .net and others. This same web server provides SOAP and REST access to Virtuoso stored procedures, supporting a broad set of WS protocols such as WS-Security, WS-Reliable Messaging and others. A BPEL4WS run time is also available as part of Virtuosos SOA suite.
Virtuoso has a built-in WebDAV? repository. This can host static and dynamic web content and optionally provides versioning. The WebDAV? repository is tested to interoperate with WebDAV? clients built into Windows XP, Mac OSX and others and makes Virtuoso a convenient and secure place for keeping ones files on the net. Further, Virtuoso provides automatic metadata extraction and full text searching for supported content types.
Open Virtuoso supports SPARQL embedded into SQL for querying RDF data stored in Virtuosos database. SPARQL benefits from low-level support in the engine itself, such as SPARQL aware type casting rules and a dedicated IRI data type. This is the newest and fastest developing area in Virtuoso.
