Global Assassin is a text-based action game.

The Global Assassin game is a multiplayer, shoot-em-up game set in the first person, and yet its text-based.

The year is 2035, and robots have taken over the Earth. Most humans died during the invasion or were forced to flee the planet. You are part of a small resistance that has managed to survive underground and is now prepared to strike back.

As a trained assassin, your objective is to return to the Earths surface, stealthily move through the worlds major cities, and systematically rid the planet of its invaders.

The details of the game are as follows.

The battlefield consists of 20 cities around the globe.

These cities have been connected for your mission by an ellaborate portal system.

Use the portals to move between cities as you search for and destroy the robots.

You are armed with a gun, bullets, and grenades.

To successfully strike an invader, you and your target must occupy the same city at the precise moment you attack.

You can lay a mine in a given city, and the very next player to enter that city trips the mine.

You remain alive as long as you have health points.

Over time, you automatically earn back health points, bullets, and grenades.

This is a multiplayer game. You may or may not be the only assassin on the planet!

MySQL Global User Variables UDF is a MySQL extension to store persistent variables.

This shared library adds simple user functions to MySQL in order to keep persistent shared variables in memory. These variables and their values are available to all clients. Any data can be stored into these persistent variables, including BLOBs. Since updates are atomic and way faster than MEMORY tables, this is an easy and efficient way to handle counters and sequences.

Usage:

Storing a value

An unlimited number of user variables can be created, as long as memory is available.
The GLOBAL_STORE(, ) stores a new shared global variable.

Examples:

mysql> DO GLOBAL_STORE("online_users", 42);
mysql> DO GLOBAL_STORE("secret_key", "pajfUyfnd");

The GLOBAL_STORE() function always returns 1 unless an error occurred.

Fetching a value

Reading the value of a variable is the job of the GLOBAL_GET() function.
The value is returned, or NULL is the variable is undefined.

Example:

mysql> SELECT GLOBAL_GET("online_users;);
42

mysql> SELECT id FROM pxs WHERE secret_key = GLOBAL_GET("secret_key");
1

Atomic increments

A single function call can read the previous value, add an integer (that can be negative), and store the new value into the variable.

The function is GLOBAL_ADD(, ) and the return value is the new value of the variable.
Updates are always atomic, if the old value is 18 and you add 1, you will always get back 19.

Example:

mysql> DO GLOBAL_ADD("online_users", 1);
mysql> SELECT GLOBAL_ADD("online_users", -4);
39

If the value of a variable was a string, the new value is the increment:

mysql> SELECT GLOBAL_ADD("secret_key", 12);
12

Adding a value to an undefined variable returns NULL.
A handy variant is GLOBAL_ADDP(, ). GLOBAL_ADDP() is similar to GLOBAL_ADD() but returns the PREVIOUS value of the variable instead of the new one.

Example:

mysql> DO GLOBAL_SET("xxx", 10);
mysql> SELECT GLOBAL_ADDP("xxx", 1);
10
mysql> SELECT GLOBAL_ADDP("xxx", 1);
11

Installation:

On most systems, compiling and installing the library should be as simple as typing (as root):

make install

The shared library is installed as /usr/local/lib/udf_global_user_variables.so

If the base directory of your MySQL installation is not in /usr/local, just type:

make

and then copy udf_global_user_variables.so to the right location for UDFs on your system (maybe /usr/lib/).

The name of a variable is limited to 256 bytes. If that limit is too low for your specific application, just edit the MAX_NAME_LENGTH variable on top of the .c file and reinstall. Variable names can contain binary characters.

Values are limited to 65536 bytes. If that limit is too low for you, edit the MAX_VALUE_LENGTH variable and reinstall.

Global Village project is a gnome application designed to place a front-end, or graphical user interface onto the CLI interface of Xplanet, by Hari Nair.
Originally intended to create and update the desktop wallpaper in a gnome environment, showing a traditional rectangular projection of the planet Earth, the scope of the project has been expanded. Global Village now provides as many of the features of Xplanet as seem reasonable, and with the ability for plugins the scope is nearly limitless. But do take it with a grain of salt...
Current Status
Currently, Global Village is barely functional. It can be considered in the pre-alpha stage of development.
It can currently show a preview of the final image, and then display that image on the desktop at user specified intervals (in seconds), and has an icon in the notification area of the Gnome panel.
Plugins are semi-working, but undergoing a lot of change as I decide what they do adn dont need to be capable of. The idea is that plugins will manage all the extra features users require, like cloudmaps, marker and arc files.
Main features:
- Select a planet.
- Select a projection.
- Bodys North Type.
- Rotate the bodys North Pole
- The Zoom level
- The Suns glare
- Latitude and Longitude, which can be set as:
- North Pole
- South Pole
- Equator
- Random Latitude and Longitude
- Or any number of user configerable locations.

vars::global is a Perl module that tries to make global variables a little safer.

SYNOPSIS

# In the place/package where we want to create globals
use vars::global create => qw( $foo @bar %baz );

# Add some more global symbols
vars::global->create(qw( $hello @world %now ));

# Somewhere else, where we need to access those globals
use vars::global qw( $foo @bar %baz );

# Dont try to use globals that do not exist
use vars::global qw( $Foo ); # typo, croaks
use vars::global qw( @inexistent ); # we dont create by default
# use create as above

# You can also import and create new globals
use vars::global qw( $foo %baz ), create => qw( $hey @joe );

# If youre lazy, you can import all the globals defined so far
use vars::global :all;

This module lets you define global variables and gain a slight advantage over blind use of package variables.

The global variables live inside the vars::global package, with the names given by the user. Where the advantage? Its two-fold:

there is an import mechanism that lets you access the global variable without the need to fully qualify its name (i.e. using $foo instead of $vars::global::foo);
the import mechanism ensures that you can import only the global variables that have been explicitly declared so far, which reduces the possibility of a typo.
If you have already "created" the global variable $foo, the import operation is equivalent to do:
*{__PACKAGE__ . ::foo} = $vars::global::foo;
that is, the package variable in the current package is made an alias for the global variable.

The anti-typo check is simply obtained by doing a check before the above import.
Typical usage is as follows:

creation

Early in the module or in the program you create variables prepending the create word, as follows:

use vars::global create => qw( $foo @bar %baz );

access

In the modules where you need to access a given global variable, you can import them very simply:

use vars::global qw( $foo %baz ); # I dont need @bar here ;)

The creation step above automatically imports all the new globals into the current package.

GFS (Global File System) is a cluster file system. It allows a cluster of computers to simultaneously use a block device that is shared between them (with FC, iSCSI, NBD, etc...). GFS reads and writes to the block device like a local filesystem, but also uses a lock module to allow the computers coordinate their I/O so filesystem consistency is maintained. One of the nifty features of GFS is perfect consistency -- changes made to the filesystem on one machine show up immediately on all other machines in the cluster.

GFS consists of a set of kernel patches and userspace programs.
The GFS lock module lock_dlm depends on CMAN and DLM.
The GFS lock module lock_gulm depends on GULM.
The GFS lock module lock_nolock depends on nothing.
Some GFS tools depend on the iddev library.

Building and Installing

1. build and install from cluster tree
cd cluster
./configure --kernel_src=/path/to/kernel
make; make install

- This builds and installs kernel modules, libraries and user programs.

- Kernel modules can also be built within the original kernel source tree by applying the kernel patches from cman-kernel/patches, dlm-kernel/patches and gfs-kernel/patches.

2. build device mapper user space
cd device-mapper
./configure
make; make install

3. build lvm2/clvm
cd LVM2
./configure --with-clvmd --with-cluster=shared
make; make install
LVM2/scripts/clvmd_fix_conf.sh /usr/lib

Load kernel modules

depmod -a
modprobe dm-mod
modprobe gfs
modprobe lock_dlm

Modules that should be loaded: lock_dlm, dlm, cman, gfs, lock_harness and dm-mod if device-mapper was built as a module.

Startup procedure

Run these commands on each cluster node:

> ccsd - Starts the CCS daemon
> cman_tool join - Joins the cluster
> fence_tool join - Joins the fence domain (starts fenced)
> clvmd - Starts the CLVM daemon
> vgchange -aly - Activates LVM volumes (locally)
> mount -t gfs /dev/vg/lvol /mnt - Mounts a GFS file system

Shutdown procedure

Run these commands on each cluster node:

> umount /mnt - Unmounts a GFS file system
> vgchange -aln - Deactivates LVM volumes (locally)
> killall clvmd - Stops the CLVM daemon
> fence_tool leave - Leaves the fence domain (stops fenced)
> cman_tool leave - Leaves the cluster
> killall ccsd - Stops the CCS daemon

Sourdough is a comprehensive web application framework for PHP5. Sourdough provides developers with real-world solutions for common system components such as User Management, Session Handling, User Authentication, Exception Handling and Logging, Template System as well as Form Building and Handling.
Sourdough project does also include a database abstraction layer with excellent support for the popular MySQL database as well as support for many other database systems like PostgreSQL, MSSQL and the new lightweight SQLite.
Sourdoughs extensive feature set can also simplify or eliminate many common, and often tedious, programming tasks.
Main features:
- Built for PHP5: new object model
- Fully object-oriented API
- Contains extensive unit test framework
- Truly independent. Database interactions with Sourdough are truly independent.
- Easy to use. All modules are accessed by a global factory. Dependencies are resolved by Sourdough itself.
Sourdough is a YAPF - Yet Another PHP Framework. Especially now, as interest on PHP 5 is growing, there are more and more frameworks beeing developed. Each of them provides us with nicer code, more functionality and higher abstraction. Still, there is no perfect framework.
Some frameworks better fit for this project, some better fit for another. And usually, designing a framework is just the consequence of a larger growing codebase of some independent projects. A framework then is usually based on existing code. No wonder there are some many frameworks around.
As far as it concerns PHP, I was pretty disappointed up to now. There was not a lot of clean code around. The only projects like PEAR, Horde or BlueShoes were huge and tricky to get into. The main goal of Sourdough is not to provide you with uncountable features and highest possible complexity. The main goal is to provide you with a easy-to-use light weighted tool for daily web applications.
The database abstraction layer that comes with Sourdough is somehow more flexible than others. It attempts to make your database applications completely portable without loosing the power of your RDBMS.
Sourdough does not intend to be the perfect PHP framework. It just wants to open your eyes if you havent found anything useful yet. Give it a try!
Enhancements:
- This release contains extended Captcha image verification and various additions.

JSignal is a loose port of the signal system implemented by GTKs GLib. JSignal project uses signals and handlers to allow for the registration of callback functions to events.
To use JSignal those classes which will emit signals (cause events) must register the signals that each class will emit. Note that if a class extends another class (has a superclass) it will inherit any signals registered by the parent class and can emit those signals as well. In addition a new global-type of signal can be registered which is class non-specific. Any class can emit a global signal.
After you have a class with registered signals you can begin connecting callback functions to those signals. Callback functions are connected (registered to listen for) to signals by specifying the signal and the object instance that will emit that signal; this registration results in the creation of a handler.
Multiple handlers can be configured for the same signal on the same object instance. In addition to instance-specific signal handlers a handler can also be registered to execute when a global signal (created using j_signal_new_global) is emitted; again, regardless of emitting instance. Note that when a global signal is emitted by an instance those handlers that are registered globally (using j_signal_handler_connect_global) will be executed BEFORE any instance-specific handlers.
To emit a signal - thus causing an event - the class which registered the signal should use the j_signal_emit function and pass any additional information to the callback function via the event detail argument. This detail object should be an array of name => value pairs.
Illustrative examples are provided below.
Note: In order for signal inheritance to work properly it is recommended that a classs prototype be given a parent member which points to the constructor of the classs superclass.
Main features:
- Multiple Handlers per Event
Multiple callback functions can be registered per signal per object instance.
- Signal Inheritance
The signals registered by an objects superclass are inherited by any extending child classes.
- Ordered Handler Execution
Like the DOM event handling system all handlers set to fire in response to a particular event fire in the order they were registered.
- Chained Handler Execution
Also like the DOM event handling model, when a handler returns a value of false any subsequent handlers will NOT be executed.
- Temporary Handler Blocking
Handlers can have blocks placed against them cumulatively; allowing for the selectively temporary disabling of handlers.
- Global Signals
Signals (as used in GLib) are class-specific. A signal registered under the class type of Integer can only be emitted by Integer instances. A global signal (registered using j_signal_new_global) can be emitted by any and all instances regardless of their class. This is essentially equivelant to registering a signal using the Javascript Object class type.
- Global Handlers
As signals are traditionally class specific it follows that handlers are instance specific. However global signals can be handled by both instance-specific handlers AND global handlers. A global handler is executed whenever a global signal is emitted, regardless of the emitting instance and its class type. Note that global handlers are executed BEFORE instance-specific handlers.
