Ascension is my attempt at an email client. It makes use of the KDE libraries, so you will need KDE installed if you wish to use it (works with 3.2, might work with 3.1). Although the code is still in alpha, I have been using it as my main email client for over a year.
If you wish to try it, you would be sensible to backup your email first. Using imap should be relatively safe, but pop3 and Unix (local) mailboxes have not been so extensively tested. I take no responsibility for any loss of data while using this program. Ascension has only been tested under Linux.
The current version supports:
- IMAP (not SSL) mailboxes.
- Pop3 (not SSL) mailboxes.
- Unix mailboxes.
- Viewing of HTML messages (no HTML composing).
- Limited searching of headers.
- Dockable parts.
- Fonts and colours are configurable, as is much of the behvaiour.
Still to do:
- Support SSL connections (probably requires a rewrite of a good portion of the mailbox subsystem).
- PGP and S/MIME support.
- Virtual folders.
- A ton of ideas yet to come.
Enhancements:
- This is the first public release

Potracegui is a GUI interface for potrace and autotrace, two programs for tracing bitmapped images.
It really doesnt do much, all the dirt work is done by potrace and autotrace, my app is simply an interface: it collects informations in an easy way (hopefully) and then it launches potrace or autotrace with all the relevant options.
Potrace and autotrace, on the contrary, are great apps for tracing so that they can be scaled, rotated, and transformed in general, without loss of quality.
Well, using a GUI sometimes is more comfortable (particularly if working with images), even if Im a strong supporter of command-line programs. On the other hand, Potracegui (thanks to Jakub Stachowski) can now load remote files (web, ftp...), use any image format recognized by KDE (potrace uses only a few bitmapped formats) and support drag and drop.
Installation:
Potracegui is installed with the usual:
./configure
make
su
make install
Installation on SuSE linux + kde 3.1 or KDE 3.2
If you are using SuSE, you have to specify to configure the directory where KDE is installed (/opt/kde3):
./configure --prefix=/opt/kde3
make
su
make install
Installation on Mandrake 9.2 with KDE3.2:
If you are using Mandrake and NVIDIA drivers, you have to consider two problems before compiling Potracegui:
Potracegui expects to find the library /usr/X11R6/lib/libGL.la, but in this distribution the library is installed in /usr/lib/libGL.la. All you have to do is symlink it:
cd /usr/X11R6/lib
ln -s /usr/lib/libGL.la .
Enhancements:
- Quick bugfix: deleted debug() method from options.cpp

The SR-RTP library enables real-time streaming applications (such as streaming MPEG-4 video) to cope with packet loss, variable bandwidth, and variable delay on the Internet.

It provides a means for selective retransmission of lost packets in a fashion that is backwards-compatible with RTP. Additionally, it provides integration with the Congestion Manager to provide a system capable of performing TCP- friendly streaming of real-time data.

Installation:

The `configure shell script attempts to guess correct values for various system-dependent variables used during compilation.

It uses those values to create a `Makefile in each directory of the package. It may also create one or more `.h files containing system-dependent definitions.

Finally, it creates a shell script `config.status that you can run in the future to recreate the current configuration, a file `config.cache that saves the results of its tests to speed up reconfiguring, and a file `config.log containing compiler output (useful mainly for debugging `configure).

If you need to do unusual things to compile the package, please try to figure out how `configure could check whether to do them, and mail diffs or instructions to the address given in the `README so they can be considered for the next release.

If at some point `config.cache contains results you dont want to keep, you may remove or edit it.

The file `configure.in is used to create `configure by a program called `autoconf. You only need `configure.in if you want to change it or regenerate `configure using a newer version of `autoconf.

The simplest way to compile this package is:

1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute
`configure itself.

Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.

2. Type `make to compile the package.

3. Optionally, type `make check to run any self-tests that come with the package.

4. Type `make install to install the programs and any data files and documentation.

5. You can remove the program binaries and object files from the source code directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean.

There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.

PwManager is a secure password manager.
With PwManager you can easily manage your passwords. PwManager saves your passwords blowfish-encrypted in one file, so you have to remember only one master-password instead of all. Instead of the master-password you can use a chipcard, so you dont have to remember a password to access the list.
Main features:
- Manage passwords the convenient way with the support of password categories, five information columns and an additional comment field.
- Locking mechanism to prevent strangers from looking at your passwords while you are away and not using PwManager.
- Deep-Locking mechanism to encrypt all security critical data, write it to disk and delete it in memory. This enables you to enjoy maximum security with almost no loss of useability.
- The integrated KWallet emulation enables all applications on your KDE Desktop to access the PwManager database in an easy, flexible and secure way.
- A fairly good seaching and sorting mechanism to find entries very fast.
- Chipcard (smartcard) interface. With the chipcard you can replace the "master-password" to easily access all your passwords with a "key-card".
- Printing support to easily print out a complete list of all your passwords.
- System-Tray (kicker) icon to enable the user to access PwManager very fast.
- GPasman and KPasman interface to import and export your data to and from these file formats.

Keepass/L project is a linux port of the windows application "Keepass Password Safe".
It is a free/open-source password manager or safe which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key-disk.
So you only have to remember one single master password or insert the key-disk to unlock the whole database.
The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish).
Installation:
Make sure that the QT directory is in PATH.
1. `cd to the directory containing the packages source code and type `qmake to configure the package for your system.
2. Type `make to compile the package.
3. Type `make install to install the programs and any data files and documentation.
Enhancements:
- fixed crash when parsing config file under Win32
- fixed loss of entry icons when saving a database which was not created with KeePassX (no KPX_CUSTOM_ICONS metastream)
- introduces new metastream format for custom icons
- removed all old Qt3 support dependecies
- QtNetwork and QtSql are not longer requiered (when using Qt 4.1.3 or later)
- implemented correct UUID management for entries
- added delay of 0.3s before performing auto-type
- metastreams now get valid group IDs (KeePass/Win compatibility)
- fixed drawing errors when performing drag and drop operations in group view
- when there is no translation installed for the systems country preference but one for the same language the program will use it now
- when canceling the file dialog for the opening of an existing database a already openend database will not longer be closed
- same for the creation of a new database
- alpha blending for banner icons
- new standard banner icon
- MacOS packages: all Qt libraries are now included in the application bundle (extra installation is not longer necessary)

DupeFinder is a simple application for locating, renaming, moving and deleting duplicate files in a directory structure.
Its perfect both for users who havent kept their hard drives very well organized and need to do some cleaning to free space, and for users who like to keep lots of backup copies of important data "just in case" something bad should happen.
Main features:
Although DupeFinder is a quite small application, it should have all of the features you will need to remove and reorganize large directories full of duplicate files:
- Well designed graphical interface with full tooltip and "Whats This?" question button support, useful in an application which you probably wont need to use frequently
- Quick processing by eliminating analysis of unwanted data through file extension filtering
- View files in external applications by double-clicking
- Rename files in place or move to new locations
- Default settings disallow deletion of all copies of duplicate files to prevent accidental data loss
- Generate simple reports identifying groups of duplicate files for later processing
While everything works pretty well in most cases, there are a few issues with DupeFinder to be aware of. I hope to fix most of the following bugs sometime soon:
- May crash if files containing "~" or ":" characters are encountered
- May crash if self referencing symlinks are encountered
- Zero byte files cannot be deleted
- May not be able to delete files with Unicode characters in filename
- Display does not update if identified duplicates are moved, renamed or modified external to DupeFinder

NetMate comes from Network Measurement and Accounting System and is a flexible and extensible network measurement tool (meter).
It can be used for accounting, delay/loss measurement, packet capturing and much more. The main advantage over other existing tools is that it can be easily extended due to its modular (class-based) structure and dynamic loadable packet processing and information export modules.
