The Enhanced MetaFile format (EMF) is the native vector graphics file format on Windows. Qt is a cross-platform application development framework, widely used for the development of GUI programs. Although it provides tools for almost every aspect of software development, Qt doesn't include a straightforward solution for the export of 2D graphics to the EMF format. EmfEngine covers this lack and enables Qt-based applications to easily export graphics to the Enhanced Metafile format.
Inguma is a penetration testing and vulnerability research toolkit. The framework includes modules that discover hosts, gather information, fuzz targets, brute force user names and passwords and attempt exploits. While the current exploitation capabilities are limited, the program provides numerous tools for information gathering and target auditing.
AbulEdu Calcul Mental is a software tool that trains children in mental calculation as stipulated by the French Ministry of Education for primary schools. Activities include addition, subtraction, multiplication of integers, addition tables (+2 to +9), times tables (x2 to x9), additional additives (to 10, to 100, to 1000), multiples (of 5, 10, 15, 20, 25 and 50), and orders of magnitude (with additions, subtractions, and multiplications). There is also an editor and selective launcher.
Arx Libertatis is a cross-platform, open source port of Arx Fatalis, a 2002 first-person role-playing game developed by Arkane Studios. Arx Fatalis features crafting, melee and ranged combat, and a unique casting system where the player draws runes in real time to effect the desired spell. The Arx Libertatis source code is based on the publicly released Arx Fatalis sources. This does however not include the game data, so you need to obtain a copy of the original Arx Fatalis or its demo.
Netzob supports the expert in reverse engineering, evaluation, and simulation of communication protocols. Its main goals are to help security evaluators to assess the robustness of proprietary or unknown protocol implementations, simulate realistic communications to test third-party products (IDS, firewalls, etc.), and create an Open Source implementation of a proprietary or unknown protocol. Netzob provides a semi-automatic inferring process, and includes everything necessary to passively learn the vocabulary of a protocol and actively infer its grammar. The learnt protocol can afterward be simulated. Netzob handles text protocols (like HTTP and IRC), fixed field protocols (like IP and TCP), and variable field protocols (like ASN.1-based formats).
