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.

Devel::RingBuffer is a Perl module with shared memory ring buffers for Perl scripts diagnosis/debug.

SYNOPSIS

#
# create ringbuffer
#
use Devel::RingBuffer;
use Devel::RingBuffer::TieInt;

my $ringbuf = Devel::RingBuffer->new(
File => somefile.trace,
Rings => 20,
Slots => 20,
SlotSize => 300,
MessageSize => 256,
GlobalSize => 24 * 1024,
StopOnCreate => 0,
TraceOnCreate => 1) || die "Cant create a ring buffer.";

my $ring = $ringbuf->allocate();

Provides shared memory structures (using memory mapped files via IPC::Mmap) to be used by diagnostic and debugger applications for Perl scripts (see Devel::STrace). Using XS/C code to maximize performance, creates a set of ringbuffers with a configurable number of slots.

Each slot includes a field for a linenumber, a timestamp, and a fully qualified subroutine name. Each ring buffer also includes additional headers and fields to support diagnostic interfaces, e.g., watched expressions, command/reponse interfaces to the monitored applications, etc.

jOpenRPG project is a Java implementation of an OpenRPG client.
jOpenRPG is a pure Java implementation of the OpenRPG client. It currently supports Chat, Gametree, basic Python scripting via jython, and more.
It is distributed as an executable jar (support libraries required), or via Java Web Start, and compatible programs.
Version restrictions:
- Expect an exception when exiting the application.
- The app is currently trying to write to a file stored inside the jar and failing. Nothing to worry obout.
- jOpenRPG does *not* currently save the game tree - dont make changes you care about.
- Use the noxml for a smaller download if you already have JAXP installed, or are using java 1.4 or better.

Antiprism project is a suite of programs for the generation, manipulation, and visualisation of polyhedra.
Make a cube
This can be done with unipoly, which can be used to make all the uniform polyhedra.
unipoly cube > cube.off
Display with
off2pov -o cube.pov cube.off
povray +a +p cube.pov
Make the dual octahedron
pol_recip is used for making duals by polar reciprocation.
To make a nice compound the radius of the sphere used for reciprocation needs to be the distance from the cube centre to the mid-point of an edge, and the sphere centre must be the centre of the cube.
unipoly has centred the cube on (0, 0, 0), which is the default centre for pol_recip. The radius can be specified using the -R option and passing two adjacent vertex index numbers of the cube. Use off2pov with the -n option to display the cube with its vertex numbers.
off2pov -x vf -n -o cube.pov cube.off
povray +a +p cube.pov
Vertices 3 and 5 are adjacent, so make the dual octahedron like this, and display it.
pol_recip -R 3,5 cube.off > oct.off
off2pov -o oct.pov oct.off
povray +a +p oct.pov
Merge the polyhedra
OFF files are merged with off_merge
off_util cube.off oct.off > cub_oct.off
Display the result.
off2pov -o cub_oct.pov cub_oct.off
povray +a +p cub_oct.pov
Use colours
To make it clearer that this is a compound of a cube and octahedron the two polyhedra could be given different colours using off_color.
Colour the cube faces red, and the octahedron faces green.
off_color -f 1,0,0 cube.off > red_cube.off
off_color -f 0,1,0 oct.off > green_oct.off
Now merge and display as before, this time making the edge and vertex elements smaller than the defaults
off_util red_cube.off green_oct.off > color_cub_oct.off
off2pov -v 0.02 -e 0.016 -o color_cub_oct.pov color_cub_oct.off
povray +a +p color_cub_oct.pov
Enhancements:
- Edge handling has been improved.
- The GLU tesselator is used for all polygon tesselation, making polygon display more consistent in export formats.
- The minimum enclosing ball is used for camera positioning, allowing better use of screen space.
- Special duals can be calculated automatically.
- There is a new program which spirals points on a sphere, and another which arranges points in rings on a sphere.

Code::Perl is a Perl module to produce Perl code from a tree.

SYNOPSIS

use Code::Perl::Expr qw( :easy );

my $c = derefh(scal(hash), calls(getkey));

print $c->perl; # ($hash)->{getkey()}

Code::Perl allows you to build chunks of Perl code as a tree and then when youre finished building, the tree can output the Perl code. This is useful if you have built your own mini-language and you want to generate Perl from it. Rather than generating the Perl at parse time and having to worry about quoting, escaping, parenthese etc, you can just build a tree using Code::Perl and then dump out the correct Perl at the end.

phpGraphy is a free photo gallery PHP script released under GPL license. Since its beginning, it has been written with simplicity and efficiency in mind following the KISS philosophy.
It should fit many needs, thanks to its easy installation process, it can be setup in less than 3 min to put a small photo gallery online.
For users with thousands of pictures, dont worry as phpGraphy does use a real directory tree to store the pictures (as you probably already have on your hard-drive), youll just have to upload your whole picture collection et voila, phpGraphy will generate the thumbnails and low-resolution pictures for you and even better, it can also auto-import IPTC description in the database (if already embeded in your pictures).
phpGraphy project integrates a bunch of nice features like comments, rating, EXIF/IPTC handling.
Main features:
- On-the-fly Thumbnail/Low resolution picture generation
