Free virtual villagers software for linux

Virtual Ring Buffer (VRB) is an implementation of a character FIFO ring buffer. Virtual Ring Buffer provides direct access to the buffer so the calling program can construct output data in place, or parse input data in place, without the extra step of copying data to or from a calling program provided buffer area.
In order to facilitate this direct access, VRB makes sure that all references to buffer locations for either output or input is always a single contiguous block of memory so that the calling program does not have to deal with split buffer spaces every time the cycling of data reaches the end of the buffer and wraps around to the beginning.
Thus, the calling program is free to use any number of tools available which do not have to be aware that they are operating directly in a ring buffer. In the latest version, VRB also provides a buffer overflow protection mechanism so that buffer overflow bugs force the program to be trapped by the operating system if accessed pointers wander beyond the range of address space managed by VRB. This feature can be disabled if desired, since it occupies 2 extra pages of address space.
VRB does all this without adding any copying overhead of its own. This ability is achieved by placing a mirror image memory map immediately after the buffer that is a reference to exactly the same memory as the buffer itself. Thus a reference to the memory location immediately past the last location in the buffer accesses the same physical RAM as the beginning of the buffer.
Thus a pointer near the end of the buffer that has a length that would otherwise have to wrap around will instead extend into the mirror image space to get the same result, but without any special handling by the program.
Installation:
First extract the source where you wish to store it. One of these commands might be used within the desired directory after the tar files has been downloaded there:
bunzip2 < vrb-0.5.0.tar.bz2 | tar -xpf -
gunzip < vrb-0.5.0.tar.gz | tar -xpf -
A subdirectory called vrb-0.5.0 is created. Execute these command to change into that directory and compile the source (changing the prefix if desired):
cd vrb-0.5.0
./Configure --prefix=/usr/local
make clean
make install
Note that unlike most other source packages using a configuration system, the configure command name is capitalized. The above commands will not install the man pages at this time. To install the man pages, simply copy them to the desired location, such as:
cp -p vrb/man/man3/*.3 /usr/local/man/man3
Usage:
VRBs basic approach designed into its API is that the calling program asks for the address and length of either the empty space where output data can be placed, or the data space where input data is present (previously placed there). These steps are implemented by macros for maximum speed, and are separate for address and length. The calling program then accesses that data directly in the buffer via that address (and length).
Once the data handling is complete, the calling program decides how much of that data it has inserted into empty space, or taken from data space, and calls VRB functions to indicate the which, which updates pointers (but does not copy any data). There are also functions available to assist in doing read/write I/O. Once the man pages are installed, the command man vrb is the starting point.
Enhancements:
- A vrb_empty function was added.
- Dead code in vrb_take was cleaned up.
- A poll loop was implemented in vbuf. vbuf now uses getopt.
- Buffer size calculation and data type/format were fixed in vbuf.

Virtual Cron is a PHP library that can check whether it is time to run a periodical task. The class can be used to check whether it is time to run a task that must run from time to time.

It creates a control file to keep track the last time the task was scheduled.

The class can check the control file last modification time to determined whether it passed a given period of time since the last time the task was run.

If the given interval time has passed since the last run, the class recreates the control file and returns true to inform the application that is time to run the task again.

The "Virtual Universe" is a 3D cyberspace which offers more possibilities than just chat: it is a combination of the Web, chat, and instant messaging within a realistic, three-dimensional cyberspace.
The "Virtual Universe" is a virtual reality environment which runs on top of the Internet.
Main features:
- chat with each other
- see the chat-partner as a virtual, three-dimensional person
- interact and communicate
- be creative in many ways
- create own worlds for any desired subject
Enhancements:
- A lighting bug in .COB/.SCN loader has been fixed.

Virtual Tomcat project is a set of scripts designed to ease administration tasks involved with hosting multiple JVM instances and domains using Apache Tomcat and HTTPd.

The system (which uses jsvc to spawn instances) allows users to deploy their own applets from within their home directories, as well as allowing full access to /manager and /admin applets.

vlsf is a plugin for the LUFS package which allows to write large files (4GB and more) on primitive filesystems like FAT32.
The workaround is simple: the file is stored in small files (chunks) on the real filesystem using the same method and naming scheme as the split utility.
Installing
To install lvfs, you need the prepatched LUFS package or the original version from the LUFS homepage and the patch (see above).
To patch LUFS, do
cd lufs-0.9.7
patch -p0 < ...patchfile
./bootstrap
The rest as usual:
./configure
make
(as root) make install
cd kernel/Linux
make
(as root) insmod 2.6/lufs.ko
(or the equivalent for 2.4/lufs.o)
Version restrictions:
- chunk files must be named after foo.XY (where XY follows the split(1) scheme)
- chunk size is limited to 2GB
- Link/Symlink operations not possible with virtual files
- no cache update functions - you will see wrong data if you work on directly on underlying filesystem
Enhancements:
- In LUFS, version 0.9.7, the kernel module misses an internal cast so virtual files contain the wrong data over 4GB. The vlfs patch contains fixes, but make sure that you compile and install the fixed module.

Kool Virtual Decks project is a professional double CD player emulator like Virtual Turn Tables, BPM Studio or any other as you know.

The idea is that you can mix two songs like a DJ would make in his/her dual cd player or in his/her turntables.

Well this program is just a preview, and idea. It doesnt work yet.

If you want to join to this project or if you have any suggestion please e-mail me.
