Regexp::Compare implements a function comparing regular expressions: it returns true if all strings matched by the first regexp are also matched by the second. It's meant to be used for optimization of blacklists implemented by regular expressions (like, for example, http://www.communitywiki.org/cw/BannedContent). False return value does not imply that there's a string matched by the first regexp which isn't matched by the second - many regular expressions (i.e. those containing Perl code) are impossible to compare, and this module doesn't even implement all possible comparisons.

PHP Based API creates a tree structure using a couple of small PHP classes. This can then be converted to javascript using the printMenu() method. The tree is dynamic in IE 4 or higher, NN6/Mozilla and Opera 7, and maintains state (the collapsed/expanded status of the branches) by using cookies. Other browsers display the tree fully expanded. Each node can have an optional link and icon. New API in 1.1 with many changes (see CVS for changelog) and new features, of which most came from Chip Chapin (http://www.chipchapin.com).

Multithreaded perl script to enumerate DNS information of a domain and discover non-contiguous IP blocks. OPERATIONS: Get the host's address (A record). Get the nameservers (threaded). Get the MX record (threaded). Perform axfr queries on nameservers and get BIND VERSION (threaded). Get extra names and subdomains via google scraping (google query = "allinurl: -www site:domain"). Brute force subdomains from file, can also perform recursion on subdomain that have NS records (all threaded). Calculate C class domain network ranges and perform whois queries on them (threaded). Perform reverse lookups on netranges ( C class or/and whois netranges) (threaded). Write to domain_ips.txt file ip-blocks.

The dnscrypt-proxy provides local service, which can be used directly as your local resolver or as a DNS forwarder, encrypting and authenticating requests using the DNSCrypt [1] protocol and passing them to an upstream server. The DNSCrypt protocol uses high-speed high-security elliptic-curve cryptography and is very similar to DNSCurve [2], but focuses on securing communications between a client and its first-level resolver. While not providing end-to-end security, it protects the local network, which is often the weakest point of the chain, against man-in-the-middle attacks. It also provides some confidentiality to DNS queries. Reference links: 1. https://www.opendns.com/technology/dnscrypt/ 2. http://dnscurve.org

XEmeraldia, Drop the blocks. If you drop a square on top of one of the same color, they (as well as any neighboring blocks of the same color) will both be shaken by an "impact". The first impact will cause fractures; the second will cause the block(s) to dissolve. You can either use the arrow keys or vi-style (hjkl) keys to move/ rotate the blocks. `s' or `p' will pause the game, and if your boss comes along, `q' can be used to avoid an unpleasant confrontation. http://www.reloco.com.ar/xemeraldia/

A route-finder for cyclists in Berlin and Brandenburg. BBBike is now ported to more than 200 cities around the world - thanks to the OpenStreetMap project. For more information see the BBBike @ World homepage http://www.bbbike.org ------------------------------------------------------------------------ BBBike is an information system for cyclists in Berlin and Brandenburg (Germany). It has the following features: * Displays a map with streets, railways, rivers, parks, altitude, and other features * Finds and shows routes between two points * Route-finder can be customized to match the cyclist's preferences: fastest/nicest route, take wind directions and hills into account, etc.) * Bike power calculator * Automatically fetches the current Berlin weather data

[ edited excerpt from developer's www site ] During image processing operations such as scanning and scaling, images tend to get blurry. The blurred impression of these images is due to the fact that image pixels are averaged with their neighbors. Blurred images don't have sharp boundaries and look as though they have been taken with an unfocussed camera. Refocus is a GIMP plug-in to "refocus" the image, using a technique called FIR Wiener filtering. The traditional technique for sharpening images is to use unsharp masking. Refocus generally produces better results than unsharp masking. The plugin can be found under "Filters > Enhance > Refocus"

This site is about a seam-carving C/C++ library called Liquid Rescale. It is a free, open source implementation of the algorithm described in the paper [1] by Shai Avidan and Ariel Shamir. It aims at resizing pictures non uniformly while preserving their features, i.e. avoiding distortion of the important parts. The API is intended to be powerful, yet fast and easy to use. It supports saving and loading of the carving information, real-time scaling, manual feature selection, customizable progress report and more. Included are full documentation (in docbook format) and examples. [1] http://www.faculty.idc.ac.il/arik/imret.pdf

PyOpenGL is an interface between the Python programming language and the OpenGL library (and related libraries). The package provides interfaces to: - The OpenGL library itself, which is a three-dimensional graphical rendering interface. For more information, visit http://www.opengl.org. - The GLU library which provides access to routines for doing quadrics, tesselation etc. - The GLUT (GL UTilitity) library from Mark Kilgard, which provides a windowing environment. - The Togl (Tk/OpenGL) widget from Brian Paul and Ben Benderson (an alternative to GLUT which interfaces to Tk). The Python bindings offer some value-added tools in addition to the standard API, including support for fast processing of arrays of coordinates, trackball support, etc.

Pyexif is a Python library and associated command line tool to extract EXIF format metadata from the headers of JPEG and TIFF image files. EXIF information is typically included in images created using digital imaging devices such as digital cameras and digital film scanners. Currently, pyexif provides the following functionality: - Parse EXIF headers in JPEG files. - Parse EXIF headers in TIFF files. - Support for camera-specific MakerNote tags (e.g. Nikon, Canon, etc.). - Provide a simple cmdline interfaces to format the data in human-readable format.
