Resource::Loader is a Perl module to load different resources depending.

SYNOPSIS

use Resource::Loader;

$loader = Resource::Loader->new(
testing => 0,
verbose => 0,
cont => 0,
resources =>
[
{ name => never,
when => sub { 0 },
what => sub { die "this will never be loaded" },
},
{ name => sometimes 50%,
when => sub { int rand 2 > 0 },
what => sub { "sometimes was loaded. args: [@_]" },
whatargs => [ qw/foo bar baz/ ],
},
{ name => sometimes 66%,
when => sub { int rand @_ },
whenargs => [ 0, 1, 2 ],
what => sub { "sometimes was loaded. args: [@_]" },
whatargs => [ qw/foo bar baz/ ],
},
{ name => always,
when => sub { 1 },
what => sub { "always was loaded" },
},
],
);

$loaded = $loader->load;
$status = $loader->status;

Resource::Loader is simple at its core: You give it a list of resources. Each resource knows when it should be triggered and if its triggered, will run its code segment.

Both the when and the what are coderefs, so you can be as devious as you want in determining when a resource will be loaded and what, exactly, it does.

I originally wrote this to solve a simple problem but realized that the class is probably applicable to a whole slew of problems. I look forward to hearing to what devious ends you push this module. Really, send me an email - I love hearing about people using my toys.

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!

Resource Management Game project is a Web-based resource management game.

Resource Management Game is a PHP framework for easily creating resource management and strategy games.

Two playable games are included.

The system uses sessions to store data and should work out of the box with little or no configuration.

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

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.
