Free engagement ring settings software for linux

jSettings package is meant to provide a Java library for dealing with program settings. (I use "settings" as just another synonym for preferences, properties, etc but I chose the word settings because of the already existing Preferences and Properties frameworks in Java). It wants to be a powerful tool for the developers of Java programs that want to manipulate structures of settings.
The code (as well as this page) is at an early development and testing stage. On top of that, I am only doing it as a means to teach myself Java (Im an economist by training and by profession) , so even at later stages you can expect the quality of the code to be quite low.
If you feel like any part of the design, code, Javadoc, examples etc is silly please dont hesitate to let me know about it. Also, I would also be happy to include requested features as long as I can understand the need for them and I also know how to do it. So please write to me if you have anything to say about this project!
Main features:
- Handles INI and FSTAB type of files and settings. There is no XML support yet, but I plan to do it if it seems to be requested.
- INI settings are specified by a setting = value pair.
- FSTAB settings are defined by an array of settings, each in a predefined field. I call them like this because the structure is similar to the fstab file in UNIX environments. Logical structure is quite similar to that of XML files.
- Settings can be logically structured into sections.
- There are two degrees of hierarchy available, called hierarchical and non-hierarchical. For example, in a hierarchical organization, the settings in a file called settings.ini, containing the following lines:
[section1]
setting1=value1
[[section1-2]] //Notice the double brackets
setting1-2=value1-2
would be refered to as
settings:section1:setting1
and
settings:section1:section1-2:setting1-2
In a non-hierarchical structure they would be
settings:section1:setting1
and
settings:section1-2:setting1-2 (section1-2 is not a child of section1 anymore).
- Loads settings from external files, either from individual files in ASCII format or from archives containing several settings files.
- Includes support for default values for settings, both for ini and fstab settings.
- The advantage is that the actual ini and fstab files will only contain the deviations from the defaults.
- Includes support for system-wide and user-specific settings, for multi-user environments.
- A program would first load the defaults, then the system-wide settings and then the user-specific ones. Also when modifying the settings, there is a choice between doing it at user and at system level.
- Support for adding/modifying/deleting settings.
- Default support for validating the settings.
- Each ini-type setting and each fstab-type field have a validation rule in the form of a regular expression. When loading the value for that setting/field, it is being checked against the rule and only accepted if it confirms to the rule. Of course, if the user wants it she can have .* as the rule for each setting.
- Support for flushing the changes made to the settings to the external files.
- Extensive logging/debug messages.

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.

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.

Authenticated User Community project is a CGI-based intranet system for K-12 settings.

AUC (Authenticated User Community) is an intranet system designed for use in an educational organization but is also useful in many other settings.

It offers the ability for users to have a uniform web-based interface to discussion forums, e-mail (similar to hotmail, etc.), file management, and a searchable user database.

Also, "Interactive Classrooms" provide a means for students and teachers to have a web-based extension to their in-class interaction.

The system runs from a C-based monolithic CGI script. MySQL is used for database storage. Also, the web-based mail client supports MIME parts/attachments, IMAP, mbox, and multiple mail folders.

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

Konversation > settings > command aliases

For example: alias: np ;replacement: /exec np

Sol Manager is a tool to manage your source files and configuration settings. SolMgr organizes project information in compiler- and platform-independent descriptions and allows conversion to native build scripts, such as makefiles or MS Visual Studio solutions.

GUI is provided to visually control project configurations, and to perform everyday project management tasks such as files addition/removal, dependency management etc.

Notice: SolMgr is under heavy development currently, so it lacks many features and functionality.
