Infins Picture Gallery (IPG) is an image gallery system for Web sites that is easy to install, reads all files from a directory set in the config file.

Infins Picture Gallery resizes and caches images dynamically, counts the number of times an image is viewed, and allows visitors to comment on and vote for your images.

You can optionaly provide additional text for each image.

libptp2 is a library used to communicate with PTP devices like still imaging cameras or MP3 players (KODAK mc3).
You can download files or tweak camera properties using ptpcam program boundled with libptp2.
Supported Cameras
The list of cameras implementing PTP is constantly growing. Most (if not all) USB still cameras designed after 2002 are supporting PTP. Below is the list of vendors implementing PTP in their cameras:
- Kodak
- HP
- Nikon
- Canon
- Panasonic
- Olympus
- Konica
- Minolta
- Fuji
- Ricoh
- Sony
More are comming...
Please note that if your camera is supporting PTP it does not mean that it is capable of performing all PTP operations (like trigerring capture, uploading files or tweaking properties). Sony cameras are good example of poor PTP implementation where the only thing you can do is downloading files. Sony even breaks the USB specification assigning all its cameras the same product/vendor IDs so dont buy Sony if you want to stay out of problems.
Currently most PTP features are supported. Uploading/downloading files, taking pictures and setting camera properties is supported as long as your camera supports it. However there are many Vendor Extensions that are not supported.
For example Canon uses some proprietary extension operations to take pictures (entering capture mode, extending lens and so on), Nikon introduces proprietary PTP properties.
Unfortunately I have access to couple of Kodak cameras only so to help support extension features you may send me a patch or donate/lend the camera.
Enhancements:
- A number of bugs were fixed, including leaving the camera in an unpredictable state when an I/O error occurs.
- The projects own reimplementation of the old libusb interface (IOCTL_USB_BULK) is used instead of the new URB interface, which is 20% to 50% slower and sometime leads to I/O errors.
- File time preservation across download was added.
- Better capture support was added.
- A bug that caused files over 2MB to be corrupted while downloading was fixed.
- The --loop-capture feature was added.
- Configure errors and parralel build with make -j were fixed.

SPGM is a PHP script that displays picture galleries on the web. It is intended to provide a very simple way to set up online photo albums: creating directories, filling them with pictures and uploading to your website... That is what its all about !
Several cool features are also included, while keeping in mind that the program aims to be as lightweight, simple and portable as possible. Dont expect automatic thumbnail generation, advanced search functions, nor per-gallery full statistics then.
SPGM generates XHTML 1.0 Strict compliant code and makes extensive use of CSS stylesheets to render galleries. It only requires PHP version 4 or higher and does not rely on image manipulation libraries (like GD), or any database system whatsoever.
Main features:
- gallery/picture captioning
- unlimited sub-galleries
- per gallery complete configuration (inheritance supported)
- several sort options for both pictures and galleries
- random/fixed thumbnails used for gallery previews
- new pictures highlighting
- hidden galleries
- EXIF support
- slideshow mode
- easy integration into websites
- multi-language support (29 languages are currently provided)
- flavors (themes) available for use
Enhancements:
- This is a maintenance release that provides various bugfixes and small features.
- People who want to upgrade from previous versions should pay attention to the release notes, as a few configuration files must be updated as well.

View Picture project is an SDL-based image viewer for Linux and FreeBSD that supports slideshows, fullscreen, zoom, and arbitrary movement through the image list.
Main features:
- HTTP updated to 1.1
- Only hide cursor when fullscreen
- Fixed image count estimate
- configure-time X prefix
- fixed potential buffer overflow issues

Natural Language Toolkit is a suite of Python libraries and programs for symbolic and statistical natural language processing. NLTK includes graphical demonstrations and sample data.
It is accompanied by extensive documentation, including tutorials that explain the underlying concepts behind the language processing tasks supported by the toolkit.
Documentation:
A substantial amount of documentation about how to use NLTK is available from the nltk home page:
< http://nltk.sourceforge.net >
In particular, the NLTK home page contains three types of documentation:
- Tutorials teach students how to use the toolkit, in the context of performing specific tasks. They are appropriate for anyone who wishes to learn how to use the toolkit.
< http://nltk.sourceforge.net/tutorial/ >
- The toolkits reference documentation describes every module, interface, class, method, function, and variable in the toolkit. This documentation should be useful to both users and developers.
< http://nltk.sourceforge.net/ref/nltk.html >
- A number of technical reports are available. These reports explain and justify the toolkits design and implementation. They are used by the developers of the toolkit to guide and document the toolkits construction. Students can consult these reports if they would like further information about how the toolkit is designed and why it is designed that way.
< http://nltk.sourceforge.net/tech/ >

Sound Mural is a picture-to-sound converter plugin for Xpaint.
An image that has been loaded or composed in Xpaint is treated as a spectrogram, and the corresponding audio is written out as a WAV file.
Examples of what Sound Mural can do, can be seen and heard on the Sound Mural Web page.
To use sound mural, you need an XPaint that supports loading precompiled filters. Future official versions of XPaint might support this, but until then you can download the source here.
The modification adds a "Load Precompiled Filter" menu item to the C_Script menu. It pops open a file selection box, and you select a .so file which contains a precompiled filter, which it loads.
After it is loaded, you can run the filter from the "User Defined Filter" in the "Filters" menu. Although this modification was made to XPaint to support Sound Mural, it might be generally useful.
Your X needs to be running in 24 bit color mode or better. Otherwise it will work but performance will be bad. It is probably a good idea to use a pure white background color in XPaint.
Non-white background colors result in constant background noise in the output of Sound Mural. And pure white pixels require no processing, so it goes much faster if most of the image is pure white.
Installation and use:
Type make to compile. You must have an XPaint that has the PRECOMPILED_FILTERS feature. If you have that, then you can load this module from
Selectors -> C_Script_Editor -> File -> Load_Precompiled_Filter
After it is loaded, you invoke Sound Mural by
Filters -> User_Defined_Filter
Each time you invoke sound mural, it will render the canvas as audio, and write a WAV file to the location specified in soundmural.c. The default location is /tmp/soundmural.wav.
Enhancements:
- Sound Mural is now a freestanding command line program.
- It reads a PNG on stdin and writes WAV on stdout.

Domino on Acid project is a weird colorful solitaire variant of dominoes that visualizes natural deduction.

Superficially, Dominoes on Acid is a solitaire variant of Dominoes with weird colorful tiles (and this view is enough to play the game).

But on a deeper level it is a GUI for natural deduction.

Every completed domino is equivalent to a proof of a tautology in classical propositional logic.

The game can be played online as an applet or offline as an application.

It is built on a simple isometric engine that can be used independent of the game.
