Wally is a Qt4 wallpaper changer using multiple sources like files, folders, FTP remote folders, Flickr, Yahoo!, Panoramio, Ipernity, Photobucket, Buzznet, Picasa, Smugmug, Google, Vladstudio, and deviantART images. It is available in many languages. Supported Linux window managers are GNOME, GnomeShell, KDE3, KDE4, XFCE4, BlackBox, FluxBox, Window Maker, and FVWM (experimental).
AutoWallpaper is a cross-platform desktop wallpaper changing utility. It automatically (or manually) changes the desktop wallpaper at a specified time interval set by the user. It runs in the background with a system tray icon that is visible when the application is running. It is written in Visual C# .NET 2008 (Windows versions) and Qt 4.4.3/4.5.0 (Linux/others).
SynchroDir is a backup and synchronization utility. Each backup is the subject of a recordable "backup project". This feature allows you to save projects corresponding to different computers, servers, external hard drives, USB keys, etc. You can also backup data of computer Y to computer Z from a controlling computer X. Each backup project includes an unlimited number of "jobs". At the end of the backup process, a log file is available. Each job has a source and a destination, each corresponding to a volume or a directory. The volume or directory must be "mounted", either locally or over the network.
YAGF is a graphical frontend for the cuneiform and tesseract OCR tools. It lets you open already scanned image files or obtain new images via XSane (scanning results are automatically passed to YAGF). Once you have a scanned image you can prepare it for recognition, select particular image areas for recognition, set the recognition language and so on. Recognized text is displayed in an editor window where it can be spell-checked, corrected, saved to disk, or copied to clipboard. YAGF also provides some facilities for a multi-page recognition.
SynScope is an offline visualization and alignment tool for time-varying signals acquired from multiple sources that may differ in offset and/or sample rate. SynScope allows you to define reference points that correspond to identical events between source pairs. It then estimates the offset and resample rate to link these sources. It maps sample time from one source to the other via a link equation. Signal alignment can be inspected with synchronous visualization or resampling. With synchronous visualization, linked signals scroll together according to the link relation. With resampling, linked signals are resampled to the highest sample rate and offset-compensated.
