Zelda Classic

Zelda Classic is a tribute to (what we think is) the greatest video game of all time: Nintendo's The Legend of Zelda. It has been developed into an exact replica of the NES version that we all know and love. Beyond that, Zelda Classic allows the development of new quests that can use either the traditional graphics or enhanced graphics, as well as new enemies, items, and challenges.

Reverse proxy

A reverse proxy is a proxy server that is installed on a server network or on network equipment. Typically, reverse proxies are used in front of Web servers. All connections coming from the Internet addressed to one of the Web servers are routed through the proxy server, which may either deal with the request itself or pass the request wholly or partially to the main web servers.

A reverse proxy dispatches in-bound network traffic to a set of servers, presenting a single interface to the caller. For example, a reverse proxy could be used for load balancing a cluster of web servers. In contrast, a forward proxy acts as a proxy for out-bound traffic. For example, an ISP may use a proxy to forward HTTP traffic from its clients to external web servers on the Internet; it may also cache the results to improve performance.

FuzzDiff

FuzzDiff -- A simple tool designed to help out with crash analysis during fuzz testing. It selectively "un-fuzzes" portions of a fuzzed file that is known to cause a crash, re-launches the targeted application, and sees if it still crashes. Eventually, this will yield a file that still causes the crash, but contains a minimum set of changes from the original un-fuzzed file.
