Dynalbum is a fully dynamic automatic Web photo album generator. The album includes an index page with thumbnails, navigation tools on each album page, and four sizes of each picture.
The entire album is dynamically generated from a directory of JPEGs, TIFFs, PNGs, and GIFs when it is accessed. Unlike other photo album generators, it doesnt clutter files with thumbnails and static HTML.
DynAlbum generates each page and each scaled image (including thumbnails) dynamically every time it is accessed. This means that theres no need to keep static copies of anything but the original pictures.
INSTALLATION:
Copy the dynalbum.py program to the file "index.py" in your image directory. You need to enable mod_python for this directory. This can be accomplished either in your httpd.conf (/etc/httpd/conf/httpd.conf or /etc/httpd/conf.d/python.conf) or in a ".htaccess" file.
The .htaccess file is placed in your image and adusts web server parameters for that directory. In order to use a .htaccess file you may need to enable support using the "AllowOverride" directive in the global apache configuration.
httpd.conf example:
DirectoryIndex index.py
AddHandler python-program .py
PythonHandler mod_python.publisher
PythonInterpPerDirectory On
.htaccess file example:
DirectoryIndex index.py
AddHandler python-program .py
PythonHandler mod_python.publisher
PythonInterpPerDirectory On
and change the relevant instance of "AllowOverride None"
in httpd.conf to "AllowOverride All" to enable .htaccess
support in Apache.
Enhancements:
- Generates multi-page image indexes
- Dynamically generates ZIP archives

Designer Framework provides a highly customizable e-commerce framework.

It automatically builds e-commerce interfaces that support a products contraints and properties and can be used to model the product to be sold, automatically and dynamically generating different output formats depending on the generator used.

It includes a Java modelling application, a finite state machine described in XML as intermediate format for the customer interface, and XSLT scripts for transforming the state machine into the final interface.Designer Framework is a highly customizable e-commerce framework.

ClassyTcl is a dynamically loadable object system for Tcl. A Tcl-only as well as a C implementation is available. ClassyTcl also doesnt require patches to the Tcl core, so keeping up with new releases should be easy.

Performance is very adequate. The C version is gives extra speed, and makes it possible to implement some methods in C.

In contrast to other Tcl object systems for Tcl, it is not modeled after the object system designed for a completely different language such a C.

IMHO, it better follows the Tcl philosophy. The system is simple, but flexible. Classes and objects are dynamic, and can easily be queried, changed and debugged at runtime.

LongPlayer extends the functionality of a traditional MP3 player and is meant for people with a large MP3 or Ogg Vorbis collection who want to listen to it all day. LongPlayer chooses from dynamically generated collections of music to fill the MP3 players playlist.
It does this in a more advanced way than a traditional player, taking into account the rating of the song and the time that has passed since the song was last listened to. The GUI allows you to view, rate, replay, and delete songs previously listened to. It works with XMMS, WinAmp, and iTunes.
Enhancements:
- fixed crashes when there are no playlists
