The fstrcmp library provides an fstrcmp function that returns a number between 0.0 (nothing alike) and 1.0 (identical); this can be used to suggest likely alternatives in error messages. Fuzzy comparisons for byte arrays, wide character strings, and multi-byte character strings are also available. In addition, there are integer alternatives for systems with slow floating point emulation.
W-Meter is a tool for testing the conformance and evaluating the performance of 802.11 products. The tool is meant for injecting arbitrary frames to test the conformance of any wifi product. The tool has templates for generating various kinds of frames which can be customized for generation of specific frames. The tool can be used to elicit responses from other wifi cards to check the conformance of the card to the protocol. At present, 802.11g frames are completed.
Perl Math::FastGF2 is a Perl math module for performing arithmetic on Galois Fields. Galois Fields have applications in Cryptography (such as the AES encryption system or various threshold systems for sharing secrets) and Error-correcting Codes (eg, Rabin's Information Dispersal Algorithm or Reed-Solomon Codes). It currently implements all the primitive maths operations needed to work with Galois Field polynomials. A set of demo scripts is included that implements Shamir's Secret Sharing algorithm using the module.
x2search is a crawler based on machine learning algorithms that finds pages and documents that are similar to given positive and different to given negative examples. The learned classifiers can be exported and saved for later reuse. It features multiple settings for searching by domain/server, etc. and has a plug-in mechanism for adding document types to be searched.
