Free ring settings software for linux

simplesettings 0.5 is an excellent tool for programmers. It provides simple settings for initialization for third party apps and libraries in Python.

gnome-settings-visualeffects allows the control of the xcompmgr composite manager, it provides the user with control of the shadow radius,opacity,offsets and colour, and the speed of fades and where they are applied.
Main features:
- Splitting shadow configuration into active and inactive windows
- Adding a path locator and version checker for xcompmgr/transset
- Incorporating window translucency (decided on a minimum of 25%)
- Window translucency can be added to active/inactive windows by single windows or window types i.e. File Chooser, applications or application children, and Im hoping that I can make this persistent.
- Increase compatibility with gdesklets
- Propose to luminocity developers a configuration standard for these types of settings, therefore improving the future of the project.
- Incorporate code from xcompmgr/transset to reduce reliance on what are intended to be demos rather than real life tools.
- Notification area tool/Panel applet for accessing effects quickly.

Chart Taglibs is a free taglib (JSP 1.1) library for JFreeChart.
These are easy to use, and allow the developer to draw any graphics supported by JFreeChart using only the tags.
Chart Taglibs currently supports pie charts (2D & 3D), bar charts (2D & 3D), and line charts.
Enhancements:
- New charts are supported: 3D Line charts, Area chars, Ring charts, Stacked Bar charts, Stacked 3D Bar charts, Stacked Area charts, and Waterfall charts.
- A minor bug was fixed to avoid a null pointer exception.
- A new Web page with documentation and screenshots was added.

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.

XiStrat, also known as Extended Strategy is in particular about turn-based, networked multiplayer, non-cooperative, zero-sum, abstract strategy board games (e.g., Chess, Go, Reversi variants, etc.) on 3D-visualized polyhedra and contains a server, client GUI, autoplayer engine, utilities and documentation.
Besides related recreational modern mathematics (single agent, cellular automata, graph/group/complexity/knot theory, discrete geometry, algebra, combinatorics, mathematical physics) is dealt with.
Enhancements:
- New graphs were added, including a Costa discrete minimal surface, sporadic Mathieu M(24), Kleins quartic L2(7), S(5), and A(6).
- The documentation was changed to MathML and contains links to the underlying mathematics (representations, modules, ring, invariants, groups of Lie type, second cohomology).
- The construction of a Schur cover of holonomy groups, morphing, and 2-body systems were implemented.
- Java generics, J3DBuffer, and procedural 3D texture with Perlin noise are now used.

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.

AmaroK now playing is a script that displays the song you are currently playing with amaroK.

Add it to, /usr/share/apps/konversation/scripts

Then add it to command aliases
