PostGIS adds support for geographic objects to the PostgreSQL object-relational
database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing
it to be used as a backend spatial database for geographic information systems
(GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the
OpenGIS "Simple Features Specification for SQL" and has been certified as
compliant with the "Types and Functions" profile.
PostGIS development was started by Refractions Research as a project in open
source spatial database technology. PostGIS is released under the GNU General
Public License. PostGIS continues to be developed by a group of contributors led
by a Project Steering Committee and new features continue to be added.

psycopg2 is a PostgreSQL database adapter for the Python programming language.
It was written from scratch with the aim of being small, fast and stable. It
supports the full Python DBAPI-2.0 and is thread safe.
psycopg2 is different from the other database adapter because it was designed
for heavily multi-threaded applications that create and destroy lots of cursors
and make a conspicuous number of concurrent INSERTs or UPDATEs. Every open
Python connection keeps a pool of real (UNIX or TCP/IP) connections to the
database. Every time a new cursor is created, a new connection does not need to
be opened; instead one of the unused connections from the pool is used. That
makes psycopg very fast in typical client-server applications that create a
servicing thread every time a client request arrives.
Apache HBase is an open-source, distributed, versioned, non-relational database
modeled after Google's Bigtable: A Distributed Storage System for Structured
Data by Chang et al. Just as Bigtable leverages the distributed data storage
provided by the Google File System, Apache HBase provides Bigtable-like
capabilities on top of Hadoop and HDFS.
Features:
-- Linear and modular scalability
-- Strictly consistent reads and writes
-- Automatic and configurable sharding of tables
-- Automatic failover support between RegionServers
-- Convenient base classes for backing Hadoop MapReduce jobs with
Apache HBase tables
-- Easy to use Java API for client access
-- Block cache and Bloom Filters for real-time queries
-- Query predicate push down via server side Filters
-- Thrift gateway and a REST-ful Web service that supports XML, Protobuf
and binary data encoding options
-- Extensible jruby-based (JIRB) shell
-- Support for exporting metrics via the Hadoop metrics subsystem to files
or Ganglia, or via JMX
Darcs is a free, open source revision control system. It is:
* Distributed: Every user has access to the full command set, removing
boundaries between server and client or committer and non-committers.
* Interactive: Darcs is easy to learn and efficient to use because it
asks you questions in response to simple commands, giving you choices in
your work flow. You can choose to record one change in a file, while
ignoring another. As you update from upstream, you can review each patch
name, even the full "diff" for interesting patches.
* Smart: Originally developed by physicist David Roundy, darcs is based
on a unique algebra of patches.
This smartness lets you respond to changing demands in ways that would
otherwise not be possible. Learn more about spontaneous branches with
darcs.
This package contains HTML documentation for the Root framework.
The installed package is 110 MB large.
ROOT stand for "<R>OOTs <O>bject-<O>riented <T>echnologies" - it is an object
oriented data analysis framework written in C++. ROOT has its origin at the
Centre Europeenne pour la Recherche Nucleaire (CERN) and is a cross platform
tool well-known to high energy physicists, but it's also used in a wide range
of other data analysis applications. The system consists of the C/C++
interpreter CINT (for interactive development and rapid prototyping) and
hundreds of classes, which provides functionalities u.a. for:
- Data Histogram and Minimization Operations
- Linear Algebra, Matrix and Vector Operations
- Tree, Ntuple and other Data Containers/Structures
- 2D Graphics, 3D Graphics and Detector Geometry Modeling
- Graphical User Interface
- Operating System and Networking Interface
- Inline Documentation and PostScript Interface
- PROOF Server (parallel computing)
EventMachine implements a fast, single-threaded engine for arbitrary network
communications. It's extremely easy to use in Ruby. EventMachine wraps all
interactions with IP sockets, allowing programs to concentrate on the
implementation of network protocols. It can be used to create both network
servers and clients. To create a server or client, a Ruby program only needs
to specify the IP address and port, and provide a Module that implements the
communications protocol. Implementations of several standard network protocols
are provided with the package, primarily to serve as examples. The real goal
of EventMachine is to enable programs to easily interface with other programs
using TCP/IP, especially if custom protocols are required.
Battle Tanks is a funny battle on your desk, where you can choose one of
three vehicles and eliminate your enemy using the whole arsenal of weapons.
It has original cartoon-like graphics and cool music, its fun and dynamic,
it has several network modes for deathmatch and cooperative -- what else is
needed to have some fun with your friends? And all is packed and ready for
you in Battle Tanks. Some of the game highlights:
* Three vehicles: tank, Shilka, and rocket launcher, each having its
special features
* Lots of weapons: four types of ammo, six types of rockets, landing
troops, mines, etc.
* 13 multiplayer maps (nine ones for deathmatch and four ones for
cooperative mode) in different locations such as city, village, forest,
desert, etc.
* Game world that reacts on player: roads have traffic, buildings can be
destroyed, weather effects are simulated
* Lots of war objects: troops, vehicles, helicopters, etc.
* Keyboard and gamepad are supported
* Dedicated server mode (headless)
Cube is a 3D First Person Shooter that uses OpenGL and SDL. It features:
- Single- and multi-player gameplay
- In-engine editing of geometry in full 3D (you fly around the map, point
and drag stuff to select or modify it), which can even be done with
multiple people at once
- Simplistic, but effective fine grain vertex lighting that looks like
lightmapping and can do dynamic lights and shadows
- No need for any kind of map precompilation, even lighting is done on fly
- Very simplistic quad-tree world structure that can do slopes (height-
fields with caps) and slants, water
- Decent collision detection and physics
- Client/server networking that goes a long way in giving a lag-free game
experience
- Doom/Quake-style singleplayer and multiplayer game with some
uncompromising brutal old-school gameplay

The GGZ Gaming Zone - Core Client Libraries
===========================================
GGZ Gaming Zone core client libraries provides the common procedures
and utilities required to run the GGZ client and games. The routines
are shared by other modules in order to ease coding and promote
compatibility and stability.
This version of the client libraries (0.0.13) should provide
compatibility with version 0.0.13 clients and servers.
The core client libraries is only one part of the GGZ Gaming Zone
client setup. The following additional packages are required:
* libggz - provides commonly used functions and low-level
communications between client modules and the GGZ servers
* gtk-client/kde-client - one or more of the GGZ clients will be
required in order to login to a server, chat and launch games
* gtk-games/kde-games/sdl-games - one or more games or game packs
are required in order to launch and play games
