Document clustering project is a data mining suite to cluster a document set. This set of tools was implemented from a series of papers: "Clustering Web Pages Semantically using Combinatorial Topology", "Data mining using granular computing", and "A fast association rule algorithm based on bitmap and granular computing".
Enhancements:
- A bug with hash table has been fixed.

Eureka Public Key was created due to numerous requests for a public key application using our strong encryption techniques. The basic principle for its use is one creates their own public key and distributes the key to whomever they will be transferring encrypted files with.

When one receives a key, they import it into their key database. You can create and import as many keys as you wish. Both public keys are used in the cryption process. You select your particular public key to use and the public key of the person who will receive it.

When a file has been received you put in your public key that matches the one they used and select their public key that was used in the encryption. See the Encryption, Decryption and Import/Export sections for more information on these topics. To create a public key, click on Keys then Create Public Key or click on the gold key icon under the menu items.

All you have to do is define a name for the public key and click on Create. All encrypted files will be written to the Encryptions folder. Likewise, all decrypted files will go to the Decryptions folder. If a file already exists with the same name, it will be overwritten.

Encryption:

To Encrypt a file, click on File then Encrypt.

All you have to do is select Your public key, their public key and click on Encrypt or press enter then select the file you want to process.

The file selected will be encrypted and then placed in your Encryptions folder. Now you can send this file in the manner you prefer.

Note that this application encrypts in a binary format. In other words, it uses the full 256 character set and is not a text file. You will need to send it as an attachment if you are using email to transmit it.

Decryption:

To Decrypt a file, click on File then Decrypt.

All you have to do is select Your public key, their public key then click on Decrypt and select the file you want to process.

The file selected will be decrypted and then placed in your Decryptions folder.

Plutimikation is a math learning game for children. It trains basic calculation skills like multiplication in the number range between 1 and 100.
Its simple, it works and my daughter likes it. Its free software written for the KDE desktop.
Enhancements:

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License.
GNU Scientific Library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite.
Installation Instructions:
GSL follows the standard GNU installation procedure. To compile GSL you will need an ANSI C-compiler. After unpacking the distribution the Makefiles can be prepared using the configure command,
./configure
You can then build the library by typing,
make
Both static and shared versions of the libraries will be compiled by default. Compilation of shared libraries can be turned off by specifying the `--disable-shared option to `configure, e.g.
./configure --disable-shared
If you encounter problems building the library try using the above option, because some platforms do not support shared libraries.
For notes about problems with specific platforms and compilers see the next section of this file (below).
An extensive test suite is available. After compiling the library with "make", it can be invoked with "make check" at the top level. The test output should be directed to a file rather than a terminal, with the command,
make check > log 2>&1
to allow any errors to be examined in detail. By default, only test failures are shown. To see the complete output, set the environment variable GSL_TEST_VERBOSE=1.
If you run the tests and get some failures, please see the notes on platform specific problems below. If you find failures that are not mentioned, please report them to bug-gsl@gnu.org.
The library can be installed using the command,
make install
The default installation directory prefix is /usr/local. Consult the "Further Information" section below for instructions on installing the library in another location or changing other default compilation options.
Enhancements:
- This release adds new support for non-symmetric eigensystems, basis splines, and Mathieu functions.
- It has fixes for all bugs reported since the last release.

OpenSSH LDAP Public Key patch provides an easy way of centralizing strong user authentication by using an LDAP server for retrieving public keys instead of ~/.ssh/authorized_keys.
It uses the standard core.schema/nis.schema and strongAuthenticationUser object class, which can simplify login centralization but could introduce serious security flaws if the LDAP server is not correctly configured.
Enhancements:
- A memory leak has been fixed.
- A potential LDAP filter injection if a username has strange characters in it [()*] has been fixed.
