GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
Pactester is a tool to test proxy auto-configuration (PAC) files. PAC files are used by browsers to identify the correct proxy server for a given URL. Since the PAC file evaluation mechanism is generated inside the browser and cannot be accessed from outside, the only way to tell which proxy your browser will use for a specific URL is manual inspection of the PAC file. Unfortunately, this approach is error prone and quickly becomes impractical for large and complex PAC files. Pactester resolves this issue by simulating browser behavior.
A 'honeypot' is designed to detect server-side attacks. In contrast, a 'honeyclient' is designed to detect client-side attacks. Specifically, a honeyclient is a dedicated host that drives specially instrumented applications to access remote servers to see if those servers are behaving in a malicious manner (by compromising the client). Honeyclients can proactively detect exploits against client applications without known signatures. This framework uses a client-server model with SOAP messaging as the primary communication method, and uses the free version of VMware Server as a means of virtualizing the client environment.
