TorrentGrab is a script that searches isoHunt for specific keywords, parse results using regular expressions, and then downloads episode numbers not located in saved list. It's not too user friendly. Although configuration is straightforward, it still requires you to know regular expressions.
Rapid Photo Downloader is an application for professional and amateur photographers, designed for use on the Linux desktop. It can download photos and videos from multiple cameras, memory cards, and portable storage devices simultaneously. It provides many flexible, user-defined options for subfolder creation, photo and video renaming, and backup.
JunkBox is a lightweight Web application that can track your files and record every single click. You can get the total number of hits and statistics on who downloaded your files, and how and when. It is completely transparent, so every link looks like an ordinary link to an ordinary file.
Grab Downloading Flash Video is a Bash script designed to be called via a Linux GNOME Desktop custom shortcut key while a Flash video is playing in your Firefox or Chrome browser. The script attempts to find the file being downloaded, waits for the download to finish, and then copies it to a configured directory. Prior to Flash 10.2, it was easy to find the file yourself in the /tmp directory. But starting with version 10.2, this script is more useful because the file is deleted but internally still open. Note that this is not a universal solution. Some sites, such as YouTube, make it easy to find the URL of the Flash video file. In those cases you may have better success using a download utility such as 'youtube-dl'.
Awake File is a framework that allows Android and Java Desktop developers to very easily implement file uploads and downloads through HTTP. Security has been taken into account from the design stage: server side configuration allows you to specify strong security rules in order to protect the files. It allows listing, creation, and deletion of remote directories, calling of remote Java methods, and displays nice progress indicators to your users.
MirrorBrain is a framework to run a content delivery network using mirror servers. It solves a challenge that many popular open source projects face: a flood of download requests, often magnitudes more than a single site could practically handle. A central (and probably the most obvious) part is a "download redirector" that automatically redirects requests from Web browsers or download programs to a mirror server near them. Choosing a suitable mirror for a user's request is the key, and MirrorBrain uses geolocation and global routing data to make a sensible choice and achieve load-balancing for the mirrors at the same time. The algorithm is both sophisticated and easy to control and tune. In addition, MirrorBrain monitors mirrors, scans them for files, generates mirror lists, and more.
