BGPHist is a tool that receives MP-BGP updates, decodes them, and writes them to a database for logging and monitoring purposes. It support not only Internet routes, but also IPv4 VPN, IPV6 VPN, and L2VPN. It sounds text output (console) and MySQL databases. The the MySQL backend, there is also a simple PHP frontend. It could be used to monitor and log an ISP's customer activity for Internet and VPNs, as a passive BGP looking glass, or as a backend for some external monitoring and accounting system.
The "Sound of Sorting" is a demo program containing many integer sorting algorithms. The algorithms are visualized in real time and augmented with sound effects, which are based on the values being compared. Animation speed and sound sustain can be customized while the algorithm is running. The visualization also highlights the algorithm's internal workings, which makes the demo program very useful for teaching sorting algorithms in an undergraduate computer science course. The program also counts the number of comparisons done by an algorithm, which can then be compared to the analytically derived value. The demo is implemented using the cross-platform toolkits wxWidgets and SDL, and can be executed on Windows, Linux, and Mac.
coastal-qt is a small collection of Qt 4/5 desktop applications built around a small Qt extension library. The library mostly focuses on missing features and services like OSD desktop notifications (with DBUS bindings) and offers some convenience classes for Qt. The current applications include a GUI man page viewer, a search tool, and a desktop user notification service daemon with multicast chat.
