The YB.ORM library aims to simplify writing C++ code that has to deal with SQL databases. The goal is to provide a convenient interface like SQLAlchemy (Python) or Hibernate (Java). The library itself is cross-platform and supports a variety of SQL dialects: SQLite3, MySQL, Postgres, Oracle, and Firebird. Integration with Boost, Qt4, and wxWidgets is built-in. In a typical usage scenario, you would describe your database schema and table relationships in a simple XML-based format, generate SQL code to populate database schema with tables, generate C++ classes, add application-specific logic to the classes, and use these classes in cooperation with the Session object to query objects from the database, create new or modify/delete existing objects, or link and unlink objects using relations. Simple serialization to XML is supported along with connection pooling.
HeldenViewer makes it possible to search for, download, and view Youtube videos in a very easy to use fashion. An important feature is the concept of adding authors as favorites, in order to be notified at the next start of HeldenViewer if the author has uploaded a new video. You will no longer be interrupted by any commercials. Much like the Youtube platform, you can watch the videos while downloading and use your favorite videoplayer to do this. The only restriction is that the video player must be able to play .flv files, e.g. VideoLanClient.
Fish Sync is a file syncing application. It can transfer multiple folders between multiple machines, keeping these folders synchronized. The Fish package does not need to be available on each machine in the group, only on the machine initiating the synchronization. The Fish program is separated into two pieces, one which does the work in the background, and the other a frontend configuration tool. This separation allows the Fish service to be run on servers where a GUI interface is not desired.
animbar lets you easily create your own animation on paper and transparancy. From a set of input images, two output images are computed that are printed, one on paper and one on transparency. By moving the transparency over the paper, a fascinating animation effect is created. This animation technique has been known for hundreds of years under names such as picket fence animation, barrier grid animation, and others.
QPass is a password manager application. It enables you to store your confidential data encrypted. All entries are stored in a single-file database encrypted using the AES-256 algorithm. Each entry can contain a name, URL, username, password, and description. QPass can also generate random passwords based on mouse movements.
AstroAviBrowser is a small tool for astronomy imaging capture/processing. It allows you to open a video file, select the good frames, and save the new sequence in a new avi file using raw or lossless codecs. You may also de-bayer your frames and separate RGB plans. It's a kind of "AviRaw" for Linux.
Rocket Propulsion Analysis (RPA) is a tool for the performance prediction of rocket engines. By providing a few engine parameters such as combustion chamber pressure, used propellant components, and nozzle parameters, the program obtains chemical equilibrium composition of combustion products, determines its thermodynamic properties, and predicts the theoretical rocket performance. A robust, proven, and industry-accepted Gibbs free energy minimization approach is used to obtain the combustion composition. It can perform analysis of nozzle flows with shifting and frozen chemical equilibrium, optimization of propellant components mixture ratio for maximum specific impulse of bipropellant systems, altitude performance analysis, analysis of nozzle performance with respect to overexpansion and flow separation, throttled engine performance analysis, estimation of test (actual) nozzle performance, and nested analysis: stepping of up to four independent variables (component ratio, chamber pressure, nozzle inlet conditions, and nozzle exit conditions).
OSG composer was designed to unleash the potential of OSG developers and users. It facilitates the creation of simple to complex 3D scenes, which combine geometries from different sources. It lets you add models from different sources, place them visually using the draggers, use advanced Snap tools, add 3D text to your scene, add texture coordinates to the models, duplicate and create instances of geometries in the scene, automatically pack your scenes with all its textures in a zip file so you can share it with other users, and fix problematic models and bring them back to life.
