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.
This is a simple XBMC add-on to generate a random waltz theme following Mozart's Musical Dice Game (Musikalisches Würfelspiel). Each waltz consist of two parts: a minuet (16 bars of music) and a trio (another 16 bars). Mozart wrote a total of 272 pieces, which get randomly combined to produce a unique piece of music every time (originally the combination was obtained using a dice roll, hence the name).
Phone Spell is a PHP class which can find words which can be used to spell a phone number. It takes a given phone number and tries to find existing words with letters equivalent to the phone number digits. It uses the pspell extension to look up words, but can also use a custom dictionary to find the equivalent words.
Light source is an object which can apply a shadow to page elements based on the position of a light. It takes the identifier of a page element and changes its CSS atttributes which define shadow parameters depending on the position of a light source relative to the target element and its children elements. The shadow can be generated either with the shape of the text elements or the whole box of the target element.
