LottaNZB aims to simplify and automate downloading of binary news from Usenet. You can tell it what to download using NZB files, which are created by many Usenet search engines. It integrates nicely with GNOME desktops, but is not limited to them, and uses the mature SABnzbd software as its foundation.
SABnzbd is a cross-platform binary newsreader written in Python. It simplifies the process of downloading from Usenet dramatically, thanks to its friendly Web-based user interface and advanced built-in post-processing options that automatically verify, repair, extract, and clean up posts downloaded from Usenet. It also has a fully customizable user interface, and offers a complete API for third-party applications to hook into.
Korallenriff is a program that collects input from different network sources and stores their data into one database. For example, it can receive POP3 mail or can fetch NNTP groups and store the received messages in a database. One can then, for example, use the database data within a Web site to display the latest postings of a newsgroup or to create an online mailing list archive. Another possible use would be to build a blogging-software where one can post via email.
Remote HellaNZB GUI is a small GTK+ application to control your HellaNZB daemon. It's well integrated into your desktop. In a few clicks, you can manage your remote (or local) queue: add NZB files from your computer or from their newzbin.com ID, set priorities, see the progress of your downloads, etc. Unlike other similar projects, this one can truly add NZB files from your computer to your remote daemon; to do so, it copies them through SSH. For Remote HellaNZB GUI to work you need a running HellaNZB daemon; it does not configure it for you.
YAJNGI (Yet Another Java NewsGroup Inspector) is a client-side service that allows you to keep tabs on a set of newsgroups without having to read constantly. You will be alerted only when the configuration finds your match. YAJNGI inspects a set of Usenet newsgroups using a perfect keyword, a regexp, or any phrases that you choose. It is multi-threaded and permits a different scan interval and actions for each group. It could be used to monitor newsgroups for your name, product, your favorite arguments, for downloading your favorite newest pictures or binary files, or any other topic of interest.
