The main advantage of Capture over gPhoto is that the consecutive shots are taken without the camera lenses being closed and opened again. When taking several thousand shots in a row, this indeed lets the camera live longer.
Enhancements:
- This release adds some minor enhancements and fixes.
- The code is stable.

Picture Downloader is an app suitable for downloading pictures from websites. Picture Downloader as the name implies is an application written in C-Sharp and Gtk-Sharp made to automate the process of downloading images from websites, Perfect for TGPs.
Right now Picture Downloader is in a very early stage of development , this means bugs are still there and some features are on their way.
Main features:
- Scan HTML code to extract links to images.
- Save pictures to a desired directory.
- Filter type of pictures (jpg, jpeg, gif, png).
- Can download from secure sites (.htacces, .htpasswd).

Engauge Digitizer project is digitizing software that converts an image showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet.

Highlights for beginners include an intuitive interface and extensive context-sensitive documentation. Highlights for experts include compensation for image distortion, cartesian and polar coordinates, linear and logarithmic coordinates, automatic scanning, graphical previews, and browser help.

Fedora Digital Object Repository is an open source software which gives organizations a flexible service-oriented architecture for managing and delivering their digital content. At its core is a powerful digital object model that supports multiple views of each digital object and the relationships among digital objects.
Digital objects can encapsulate locally-managed content or make reference to remote content. Dynamic views are possible by associating web services with objects. Digital objects exist within a repository architecture that supports a variety of management functions. All functions of Fedora, both at the object and repository level, are exposed as web services. These functions can be protected with fine-grained access control policies.
This unique combination of features makes Fedora an attractive solution in a variety of domains. Some examples of applications that are built upon Fedora include library collections management, multimedia authoring systems, archival repositories, institutional repositories, and digital libraries for education.
Enhancements:
- This is a significant release of Fedora that includes a complete repackaging as a proper Web application.
- A new installer application makes it easy to setup and run.
- It now uses Servlet Filters for authentication.
- The Fedora repository can also be configured to calculate and store checksums for content.
- The RDF-based Resource Index has been tuned for better performance.
- A new high-performing RDBMS-backed triplestore has been developed that can now be plugged into the RI.

Digital Product Management Library SDK (DPML SDK) is a management platform for Java-based component development, resource management, and deployment.
The project is composed of the Transit resource management layer, the Depot multi-project build system, the Metro component management runtime engine, and the Station application management console.
Enhancements:
- Support was enhanced for the creation of composite components using URL resolvable parts (where a part is a building block defining a classloader chain, component, and deployment scenario).

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.

Myrinix - Digital Home Edition is meant to be a smart and centralized OS that can be implemented in a home environment.

Diskless client computers can connect with the server as it performs other tasks. Myrinix - Digital Home Edition is a bootable CD derived from Kanotix.
Enhancements:
- This release fixed a DBUS hang at startup on some computers and detection of USB drives as home at startup.
- An easy USB portable drive installer was added along with a locale changer for quick and easy language changes.
