Free 0.6.2 software for linux

This application is a graphical user interface to OpenSSL, RSA public keys, certificates, signing requests and revokation lists.
The keys do have an internal counter, counting its use to avoid a duplicate use of a key for creating a certificate or request. The Keys are encrypted in the database file.
Xca supports next to the usual PEM and DER format of certificates the import and export of PKCS#12 (aka *.pfx) files and the Certificate import from PKCS#7 files.
Certificates can be created by self signing it, by signing it by an other (usually CA) certificate or by signing a PKCS#10 request. Netscape SPKAC is supported since version 0.4.6. The validity dates and x509.v3 extensions can be adjusted to fit ones needs. The use of multiple certificates in CA chains is supported and a tree view of the certificates reflects the dependencies. The application takes care to not create duplicate certificates by checking the serial number(s) on import and creation of certificates.
Certificate Templates can be used to preset the input dialog with reasonable values and to simplify the process of creating certificates and requests.
Issued certificates can be revoked and the revokation list can be created and exported. External revokation lists can be imported and examined.
Main features:
- Database
- Uses one local databasefile for all settings, Keys, Requests and Certificates. IMHO it is an advantage and not a disadvantage
- transactions, recovery and db-exceptions are used to keep it consistent.
- Keys
- import and export of PEM, DER, PKCS#8 private and public RSA keys.
- Key generation with variable length
- Keys are 3-DES encrypted in database

- generate request from certificate.
- import and export in DER, PEM and PKCS#12 format.
- several export formats containing certificate chains or not.
- Signing and encryption of files added, they are written in PEM PKCS#7 format
- Export to TinyCA or "openssl ca" filestructure
- Certificates in tree view or in plain view
- Sorting of certificates by date or serial
- All known X.509 name-entry OIDs can be used in the distinguished name

Torus is a simple game inspired by Torus for DOS. The object of Torus is to clear falling toruses by aligning toruses with the same color on one of several protruding pipes (the game concept is similar to Tetris(R)). It is written in C++ with Qt and STL. Torus for win32 is written in C++ with VXCL.

KXNeur is a X Neural Switcher front-end for KDE. Its a program like Punto Switcher, but has other functionally and features.

Last version can get from svn:
svn://xneur.ru:3690/xneur/xneur and svn://xneur.ru:3690/xneur/kxneur

PS XNeur homepage ( http://xneur.ru ) on Russian only
PPS KXNeur not work without XNeur

dcache is a database library implementing a persistent first-in-first-out cache.
The database (or `cache) size limits are configured at creation time, and as soon as they are reached the oldest records are automatically removed.
dcache library has a number of commandline tools for managing the database.
dcache is a disk based caching database in a single file containing a header and fixed sized hash and data space.
The header holds variables and constants describing the database.
The hash table holds pointers into the data area and hashes of the keys. The hash function used is a crc32.
The data area consists of the data, the key, a 64bit number with application defined use, and two 32bit numbers holding key and data lengths.
The header and hash table are mapped into process address space using the mmap(2) system call. The data area is not memory mapped, thus allowing to handle multi-gigabyte files even on systems with a 32bit address space.
Main features:
- The database size is limited to 63 bits on operating systems supporting large files.
- The database size is limited to 31 bits (2 gigabytes) on operating systems not supporting large files.
- The sum of the length of key, data and record overhead is limited to 31 bits (2 gigabytes).
- The record overhead in the data area is 16 bytes.
- The number of possible keys is limited by the address space of the process, or somewhat over 200 million, whatever comes first.
- Storage of numbers is done in big endian byte order (network byte order). Databases are portable between hosts with different byte orders.
- The size of the cache and the number of records in it are set at creation time.
- The cache is cleaned up automatically, removing old records if theres not enough space for data or records.
- Deletions are supported.
- Multiple readers and writers are supported, provided that the applications lock to database.
- Keys need not be unique.
The dcache library files are published under the GNU Lesser General Public License (dont hesitate to ask me if this is a problem for you). The tools are published under the GNU GENERAL PUBLIC LICENSE.
Enhancements:
- This release fixes a few compiler and linker warnings, among them those breaking the self check when using dietlibc.
- No functional changes were done.

libcfg+ is a C library that features multi- command line and configuration file parsing.
It is possible to set up various special properties such as quoting characters, deliminator strings, file comment prefixes, multi-line postfixes, and more.
It supports many data types such as booleans, integers, decimal numbers, strings with many additional data type flags (such as multiple values for a single option).
Enhancements:
- several major documentation rewrittes for better readability and explanations (thanks to Sergei Gerasenko)
- fixed bad documentation concerning to "multiple properties manipulation" section

Kahakai is a fork of the Waimea window manager, with the intent to create a language agnostic scriptable window manager, while maintaining the original features of Waimea, and extending upon them. Kahakai is pronounced with the ca in car, the ha in hard, and ki from kite.
By "language agnostic", we mean that the scripts which control actions in the window manager are not language specific, they can be written in any language supported by SWIG. For starters, we plan on supporting Python with the addition of Ruby and Perl shortly thereafter.
Main features:
- Window/edge snapping
- Transparent window titles and menus with anti-aliased fonts
- Python scripting (Ruby/Perl support planned) used for configuration
- Dockapp support
- Pixmap styles, compatible with Blackbox/Fluxbox/Openbox & Waimea styles
- Viewports, multiple desktops
- KDE and GNOME support

EduKator is an educational program made for KDE. I made this software as a part of my thesis. Im in last year of high school.

I want to help people gain knowledge about physical and mathematical statements in a way that it is fun to do. The theory is explained and it is possible to make exercises.
My aim is to make a nice program that can be used in schools and at home.

The aim of the program is to make it as easy as possible for people to do their own personal budgets and keep track of their finances.
Main features:
- Create a budget and organize budget items into categories.
- Nominate budget items to be paid from either a cash account or via a "Direct Debit" account which allows you to save for big ticket items and ensure timely payment of scheduled bills.
- Automatically calculates how much money you must put aside each fortnight to meet all your "Direct Debit" obligations.
- Automatically tells you how much money you must have in Direct Debit account to meet your obligatory payments on any particular date.
- Record and save expenses against each of your budget categories.
- Track how your expenses relate to your budget so you can determine if you are over or under-spending in any of your categories.
- Sort your records into categories or by date.
- Comes with realistic example to show how things work.
- Allows you to export any of your reports, records, budget and Direct Debit status to the Gnumeric Spreadsheet program where they can be either printed or used for more detailed analysis.
- Allows you to export any of your reports, records, budget and Direct Debit status to the AbiWord WordProcessor program where they can be printed or incorporated into a report.
