Contractor Software allows contractors to manage their projects and interact with customers online. A contractor can post each task of a project. Each task has a start date and estimated completion date.
The client can then always know where the project is and leave comments for the contractor on each task. The contractor can also reply to the client with a follow up comment. This enhances communication and also leaves a record for reference later.

Atomorun 1.1_pre2
Atomorun project is an OpenGL Jump&Run clone. more>>
Atomorun project is an OpenGL Jump&Run clone.
In Atomorun, the character "Atomio" has to escape from an exploding nuclear bomb. The shockwave tries to catch you, so run as fast as you can!
It uses 3D OpenGL for the graphics, while the gameplay is 2D (just jump and run as fast as you can, left to right)
Enhancements:
- Forgot to put the body in a displaylist also...
- The glasses are black again (ooops)
- It is now possible to leave the "game over"-screen with a press on ENTER
- The level is now generated randomly and a little bit larger. Makes it much more difficult :)
- Redesigned the menu.
- Some code cleanup
- Added the acid fog, from which Atomio has to run away.
- Fixed bug, where you could change the direction of Atomio in the menu.
- Sound support added. (New dependency: SDL_mixer with ogg support)
- Textures are now stored in smaller and better PNGs. (New dependency: SDL_image with png support)
- If loading a PNG (or OGG) fails, it tries to load a BMP (or WAV). See docsINSTALL.win32, why. Grrr, why do I have to make a win32 build?
- Fixed menu bug. It was possible to press Escape in the menu after playing the game.
- Its now possible to change resolution and fullscreen mode with commandline arguments. Start "atomorun -h" for more help.

JavaSame project is a Same clone written in Java.
JavaSame is another Same clone written in Java.
Its based on the KSame ideas and GnomeSame images, and can be run as an applet or stand alone application.
Remove as many balls as you can. You can do it by clicking on groups of two or more balls.
The bigger group you remove the more points you get, exactly (balls-2)^2.
If you leave some unremoved balls, they are subtrackted from your points in the same manner.
For an empty field you get 1000 bonus points.
(Soon there will be a highscores list, so do Your best!)
Good luck! :)

Score Reading Trainer 0.1.3
Score Reading Trainer helps you improve your (musical) score reading skills by practicing with random scores. more>>
Score Reading Trainer helps you improve your (musical) score reading skills by practicing with random scores.
It works in a very simple way, you choose the clef, the key and the accidentals you want to practice as well as thee range of notes and then, the program generates a on-screen score with that parameters but randomizing the notes and the accidentals (and everything else that is randomizable).
The keys of the keyboard are mapped to the notes like in a piano (it would be nice to support midi in the future) and all you have to do, is press the right key for the first note you see in the score on the screen.
If you pressed the right key, the note will disapear and replaced by the second one, a diferent note, and you have to repeat the process.
As the notes are generated randomly, theres no way one can predict the following note and since several notes (as much as the screen allows) are on the screen, one can also train pre-reading (reading ahead of the current one) of the notes.
The program doesnt emit any sound (at least, yet) and its not inteded to teach rithmic or melodic concepts.
Enhancements:

SMPlayer 0.6.8 offers users a complete front-end for MPlayer, from basic features like playing videos, DVDs, and VCDs to more advanced features like support for MPlayer filters and more.
One of the most interesting features of SMPlayer: it remembers the settings of all files you play. So you start to watch a movie but you have to leave... don't worry, when you open that movie again it will resume at the same point you left it, and with the same settings: audio track, subtitles, volume...
Major Features:
- Configurable subtitles. You can choose font and size, and even colors for the subtitles.
- Audio track switching. You can choose the audio track you want to listen. Works with avi and mkv. And of course with DVDs.
- Seeking by mouse wheel. You can use your mouse wheel to go forward or backward in the video.
- Video equalizer, allows you to adjust the brightness, contrast, hue, saturation and gamma of the video image.
- Multiple speed playback. You can play at 2X, 4X... and even in slow motion.
- Filters. Several filters are available: deinterlace, postprocessing, denoise... and even a karaoke filter (voice removal).
- Audio and subtitles delay adjustment. Allows you to sync audio and subtitles.
- Advanced options, such as selecting a demuxer or video & audio codecs.
- Playlist. Allows you to enqueue several files to be played one after each other. Autorepeat and shuffle supported too.
- Preferences dialog. You can easily configure every option of SMPlayer by using a nice preferences dialog.
- Possibility to search automatically for subtitles in opensubtitles.org.
- Translations: currently SMPlayer is translated into more than 20 languages, including Spanish, German, French, Italian, Russian, Chinese, Japanese....
- It's multiplatform. Binaries available for Windows and Linux.
- SMPlayer is under the GPL license.

IFF Format Library 0.1
IFF Format Library provides header structures and utility functions for reading and writing data files in the Interchange Files. more>>
IFF Format Library provides header structures and utility functions for reading and writing data files in the Interchange Files.
The Interchange File Format is a simple structured binary file format consisting of sized and typed chunks of data, selectively readable without having to know the format of each chunk.
This functionality is similar to what XML provides for text documents, and the IFF format can indeed be viewed as a sort of a binary XML. IFFs extensibility is an excellent way of not breaking old applications when the file format changes, making it an excellent choice for your next applications data files.
The IFF is also the simplest and the smallest such data format, ensuring that your files consist of real data rather than overhead and that your code spends more time on real work than on parsing the data file. This library defines the IFF header structures and provides simple algorithms for directly writing many of your objects as chunks and containers.
Installation:
This library can be downloaded from SourceForge, as can its sole prerequisite:
libiff - The library source package.
uSTL - An STL implementation, required.
First, unpack and install uSTL, as described in its documentation. Unpack libiff and run ./configure; make install, which will install the library to /usr/local/lib and headers to /usr/local/include. ./configure --help lists available configuration options, in the usual autoconf fashion. The one thing to be aware of is that by default the library will not be completely conforming to EA85 specification. Why that is so, and why you should take the default options anyway, is discussed in detail in the next section. If you really want to use the original EA85 format, you can to pass --with-bigendian --with-2grain to configure.
Usage:
If you are using C++, chances are you already have an object-oriented design of some kind. You have a collection of objects, related to each other in some way, and you want to write them all to a file in some way. It is, of course, possible to just write them all to the file, one after the other, but that approach makes things difficult if you ever decide to change the structure of those objects, write more or fewer of them, or explain to other people how to read your format. Hence, it is desirable to create some kind of structure in the file, to be able to determine where each objects begins and ends, and what kind of object is where. When using an IFF format, youll make simple objects into chunks, and objects containing other objects into FORMs, LISTs, or CATs.
The first task is to make each of your objects readable and writable through uSTL streams. To do that youll need to define three methods, read, write, and stream_size, and create flow operator overrides with a STD_STREAMABLE macro. Here is a typical example:
#include < iff.h > // iff header includes ustl.h, but doesnt use the namespace.
using namespace ustl; // it is recommended to leave iff:: namespace on.
/// Stores players vital statistics.
class CPlayerStats {
public:
void read (istream& is);
void write (ostream& os) const;
size_t stream_size (void) const;
private:
uint16_t m_HP;
uint16_t m_MaxHP;
uint16_t m_Mana;
uint16_t m_MaxMana;
};
// Since the object is simple, and contains no other objects,
// well make it a simple chunk.
enum { // Define a chunk format for writing this object.
fmt_PlayerStats = IFF_FMT(S,T,A,T)
}; // In a hex editor youll see STAT at the beginning of the object
// making it easy to find when you want to hack something in it.
/// Reads the object from stream p is
void CPlayerStats::read (istream& is)
{
is >> m_HP >> m_MaxHP >> m_Mana >> m_MaxMana;
}
/// Writes the object to stream p os.
void CPlayerStats::write (ostream& os) const

The Interchange File Format is a simple structured binary file format consisting of sized and typed chunks of data, selectively readable without having to know the format of each chunk.
This functionality is similar to what XML provides for text documents, and the IFF format can indeed be viewed as a sort of a binary XML. IFFs extensibility is an excellent way of not breaking old applications when the file format changes, making it an excellent choice for your next applications data files.
The IFF is also the simplest and the smallest such data format, ensuring that your files consist of real data rather than overhead and that your code spends more time on real work than on parsing the data file. This library defines the IFF header structures and provides simple algorithms for directly writing many of your objects as chunks and containers.
Installation:
This library can be downloaded from SourceForge, as can its sole prerequisite:
libiff - The library source package.
uSTL - An STL implementation, required.
First, unpack and install uSTL, as described in its documentation. Unpack libiff and run ./configure; make install, which will install the library to /usr/local/lib and headers to /usr/local/include. ./configure --help lists available configuration options, in the usual autoconf fashion. The one thing to be aware of is that by default the library will not be completely conforming to EA85 specification. Why that is so, and why you should take the default options anyway, is discussed in detail in the next section. If you really want to use the original EA85 format, you can to pass --with-bigendian --with-2grain to configure.
Usage:
If you are using C++, chances are you already have an object-oriented design of some kind. You have a collection of objects, related to each other in some way, and you want to write them all to a file in some way. It is, of course, possible to just write them all to the file, one after the other, but that approach makes things difficult if you ever decide to change the structure of those objects, write more or fewer of them, or explain to other people how to read your format. Hence, it is desirable to create some kind of structure in the file, to be able to determine where each objects begins and ends, and what kind of object is where. When using an IFF format, youll make simple objects into chunks, and objects containing other objects into FORMs, LISTs, or CATs.
The first task is to make each of your objects readable and writable through uSTL streams. To do that youll need to define three methods, read, write, and stream_size, and create flow operator overrides with a STD_STREAMABLE macro. Here is a typical example:
#include < iff.h > // iff header includes ustl.h, but doesnt use the namespace.
using namespace ustl; // it is recommended to leave iff:: namespace on.
/// Stores players vital statistics.
class CPlayerStats {
public:
void read (istream& is);
void write (ostream& os) const;
size_t stream_size (void) const;
private:
uint16_t m_HP;
uint16_t m_MaxHP;
uint16_t m_Mana;
uint16_t m_MaxMana;
};
// Since the object is simple, and contains no other objects,
// well make it a simple chunk.
enum { // Define a chunk format for writing this object.
fmt_PlayerStats = IFF_FMT(S,T,A,T)
}; // In a hex editor youll see STAT at the beginning of the object
// making it easy to find when you want to hack something in it.
/// Reads the object from stream p is
void CPlayerStats::read (istream& is)

/// Writes the object to stream p os.

Popup Fortune 2
Popup Fortune displays fortunes on your root X window. more>>
Popup Fortune is a python application which takes over your root window and displays on it output of the fortune program in boxes (or whatever program you specify).
It is very much a work in progress, but I find it enjoyable to leave running, and if you do too, great.
Popup Fortune is released under the terms of the GNU GPL.
Python and X are required. Python-Xlib is also needed, but I am currently including that in the tarball, since, to my knowledge, packages for that are not too common.
In addition, if you do not specify a different command, the default is fortune, so you will need that too.

GSTP 0.5
GSTP is a binary file transfer protocol that focuses on security and anonymity. more>>
GSTP is a binary file transfer protocol that focuses on security and anonymity. It tries to do right, where FTP does wrong, especially when it comes to firewall and user/password security.
To build, use ./configure, make and make install.
Server binary is server/gstp-server. Uses server/gstp.conf as config. In config, it says it uses server/users.txt for authorisation. users.txt uses native crypt() for passwords in the second field, but its ok to leave this field empty, in which case an empty password
will be accepted.
Client binary is client/gstp-client. Takes one argument, the host to connect to. Port is always 10042.
Enhancements:
- config.h.in, server/gstp.c, server/gstp_server.h, server/server.c: Added -v and moved ssl init to before setuid()-call

Tk::form 804.027
Tk::form is a Perl module with a geometry manager based on attachment rules. more>>
Tk::form is a Perl module with a geometry manager based on attachment rules.
SYNOPSIS
$widget->form?(args)?
$widget->formOption?(args)?
The form method is used to communicate with the form Geometry Manager, a geometry manager that arranges the geometry of the children in a parent window according to attachment rules. The form geometry manager is very flexible and powerful; it can be used to emulate all the existing features of the Tk packer and placer geometry managers (see pack, place). The form method can have any of several forms, depending on Option:
$slave->form?(options)?
Sets or adjusts the attachment values of the slave window according to the -option=>value argument pairs.
-b => attachment
Abbreviation for the -bottom option.
-bottom => attachment
Specifies an attachment for the bottom edge of the slave window. The attachment must specified according to "SPECIFYING ATTACHMENTS" below.
-bottomspring => weight
Specifies the weight of the spring at the bottom edge of the slave window. See "USING SPRINGS" below.
-bp => value
Abbreviation for the -padbottom option.
-bs => weight
Abbreviation for the -bottomspring option.
-fill => style
Specifies the fillings when springs are used for this widget. The value must be x, y, both or none.
-in => $master
Places the slave window into the specified $master window. If the slave was originally in another master window, all attachment values with respect to the original master window are discarded. Even if the attachment values are the same as in the original master window, they need to be specified again. The -in flag, when needed, must appear as the first flag of options. Otherwise an error is generated.
-l => attachment
Abbreviation for the -left option.
-left => attachment
Specifies an attachment for the left edge of the slave window. The attachment must specified according to "SPECIFYING ATTACHMENTS" below.
-leftspring => weight
Specifies the weight of the spring at the left edge of the slave window. See "USING SPRINGS" below.
-lp => value
Abbreviation for the -padleft option.
-ls => weight
Abbreviation for the -leftspring option.
-padbottom => value
Specifies the amount of external padding to leave on the bottom side of the slave. The value may have any of the forms acceptable to Tk_GetPixels.
-padleft => value
Specifies the amount of external padding to leave on the left side of the slave.
-padright => value
Specifies the amount of external padding to leave on the right side of the slave.
-padtop => value
Specifies the amount of external padding to leave on the top side of the slave.
-padx => value
Specifies the amount of external padding to leave on both the left and the right sides of the slave.
-pady => value
Specifies the amount of external padding to leave on both the top and the bottom sides of the slave.
-r => attachment
Abbreviation for the -right option.
-right => attachment
Specifies an attachment for the right edge of the slave window. The attachment must specified according to "SPECIFYING ATTACHMENTS" below.
-rightspring => weight
Specifies the weight of the spring at the right edge of the slave window. See "USING SPRINGS" below.
-rp => value
Abbreviation for the -padright option.
-rs => weight
Abbreviation for the -rightspring option.
-t => attachment
Abbreviation for the -top option.
-top => attachment
Specifies an attachment for the top edge of the slave window. The attachment must specified according to "SPECIFYING ATTACHMENTS" below.
-topspring => weight
Specifies the weight of the spring at the top edge of the slave window. See "USING SPRINGS" below.
-tp => value
Abbreviation for the -padtop option.
-ts => weight
Abbreviation for the -topspring option.
$master->formCheck
This method checks whether there is circular dependency in the attachments of the masters slaves (see "CIRCULAR DEPENDENCY" below). It returns the Boolean value TRUE if it discover circular dependency and FALSE otherwise.
$slave->formForget
Removes the slave from its master and unmaps its window. The slave will no longer be managed by form. All attachment values with respect to its master window are discarded. If another slave is attached to this slave, then the attachment of the other slave will be changed to grid attachment based on its geometry.
$master->formGrid?(x_size, y_size)?
When x_size and y_size are given, this method returns the number of grids of the $master window in a pair of integers of the form (x_size, y_size). When both x_size and y_size are given, this method changes the number of horizontal and vertical grids on the master window.
$slave->formInfo?(-option)?
Queries the attachment options of a slave window. -option can be any of the options accepted by the form method. If -option is given, only the value of that option is returned. Otherwise, this method returns a list whose elements are the current configuration state of the slave given in the same option-value form that might be specified to form. The first two elements in this list list are "-in=>$master" where $master is the slaves master window.
$master->formSlaves
Returns a list of all of the slaves for the master window. The order of the slaves in the list is the same as their order in the packing order. If master has no slaves then an empty string is returned.
