Android is a
Linux-based operating system for mobile devices such as smartphones and tablet
computers. It is developed by the Open Handset Alliance led by Google.
Google purchased the initial developer of the software, Android
Inc., in 2005. The unveiling of the Android distribution in 2007 was announced
with the founding of the Open Handset Alliance, a consortium of 86 hardware,
software, and telecommunication companies devoted to advancing open standards
for mobile devices. Google releases the Android code as open-source, under the
Apache License. The Android Open Source Project (AOSP) is tasked with the
maintenance and further development of Android.
Android has a large community of developers writing applications
("apps") that extend the functionality of the devices. Developers write
primarily in a customized version of Java. Apps can be downloaded from
third-party sites or through online stores such as Android Market, the app store
run by Google. As of October 2011 there were more than 400,000 apps available
for Android, and the estimated number of applications downloaded from the
Android Market as of December 2011 exceeded 10 billion.
Android was listed as the best-selling smartphone platform
worldwide in Q4 2010 by Canalys with over 200 million Android devices in
use by November 2011. According to Google's Andy Rubin, as of December 2011
there are over 700,000 Android devices activated every day.
Koha is an open source Integrated Library System (ILS), used
world-wide by public, school and special libraries. The name koha comes from a
Māori term for a gift or donation
Koha is web-based ILS, with a SQL database (MySql preferred)
cataloguing data stored in MARC and accessible via Z39.50. The user interface is
very configurable and adaptable and has been translated into many languages.
Koha has most of the features that would be expected in an ILS, including:
Simple, clear interface for librarians and members (patrons)
Various Web 2.0 facilities like tagging and RSS feeds
Union catalog facility
Circulation and borrower management
Full acquisitions system including budgets and pricing information
(including supplier and currency conversion)
Simple acquisitions system for the smaller library
Ability to cope with any number of branches, patrons, patron categories,
item categories, items, currencies and other data
Serials system for magazines or newspapers

Free and open-source software (F/OSS, FOSS) or
free/libre/open-source software (FLOSS) is software that is both free and open
source. It is liberally licensed to grant users the right to use, copy, study,
change, and improve its design through the availability of its source code. This
approach has gained both momentum and acceptance as the potential benefits have
been increasingly recognized by both individuals and corporations.
In the context of free and open-source software, free refers to
the freedom to copy and re-use the software, rather than to the price of the
software. The Free Software Foundation, an organization that advocates the free
software model, suggests that, to understand the concept, one should "think of
free as in free speech, not as in free beer".
FOSS is an inclusive term that covers both free software and open
source software, which despite describing similar development models, have
differing cultures and philosophies. Free software focuses on the
philosophical freedoms it gives to users, whereas open source software focuses
on the perceived strengths of its peer-to-peer development model. FOSS is a
term that can be used without particular bias towards either political approach.
Welcome to Qt..
Qt is a cross-platform application framework that is widely used
for developing application software with a graphical user interface (GUI) (in
which cases Qt is classified as a widget toolkit), and also used for developing
non-GUI programs such as command-line tools and consoles for servers. Qt is most
notably used in Autodesk Maya,The Foundry's Nuke, Adobe Photoshop
Elements, OPIE, Skype, VLC media player, VirtualBox, and Mathematica, and
by the European Space Agency, DreamWorks, Google, HP, KDE,
Lucasfilm, Panasonic, Philips, Samsung, Siemens, Volvo,
and Walt Disney Animation Studios.
Qt is developed by an open source project, the Qt Project,
involving both individual developers as well as developers from Nokia, Digia,
and other companies interested in the development of Qt. Prior to the launch of
the Qt Project, it was produced by Nokia's Qt Development Frameworks division,
which came into being after Nokia's acquisition of the Norwegian company
Trolltech, the original producer of Qt. Nokia announced that it is going to drop
Symbian technologies and base their future smartphones on Microsoft platform
instead in February 2011. One month later Nokia announced the sale of Qt's
commercial licensing and professional services to Digia PLC, although Nokia will
remain the main development force behind the framework. On May 9, it was
announced on the Qt Labs website that the groundwork was being laid for the next
major version of Qt, with the expectation that Qt 5 would be released in
Qt uses standard C++ but makes extensive use of a special code
generator (called the Meta Object Compiler, or moc) together with several macros
to enrich the language. Qt can also be used in several other programming
languages via language bindings. It runs on the major desktop platforms and some
of the mobile platforms. It has extensive internationalization support. Non-GUI
features include SQL database access, XML parsing, thread management, network
support, and a unified cross-platform API for file handling.
QDistributed under the terms of the GNU Lesser General Public
License (among others), Qt is free and open source software. All editions
support a wide range of compilers, including the GCC C++ compiler and the Visual
