A quicker picker-upper. "[A] group of MIT researchers will present a new algorithm that, in a large range of practically important cases, improves on the fast Fourier transform."

4chan's texboard /prog/ invents a novel new sorting algorithm(no images, but NSFW with a few reprehensible bits thrown in) called sleep sort and translates it into most most modern programming languages. Hacker News provides analysis and finds itself impressed.

Age of the Algorithm. In the age of the algorithm, you can get just about anything you think you want, learn everything you think you need to know, by clicking on a link or typing a few words into a search bar. On SEO, content farms, old media, and 'online sweatshops.' (From Maisonneuve.)

Google recently rolled out its new instant search feature which accompanies its older "suggest" function. Both use an algorithm in an attempt to keep the search engine clean and out of trouble. The people at 2600.com are compiling a list of both objectionable and NOT objectionable terms (NSFW). [more inside]

What different sorting algorithms sound like. "[...] audibilization is just one of many ways to generate sound from running sorting algorithms. Here on every comparison of two numbers (elements) I play (mixing) sin waves with frequencies modulated by values of these numbers." Two older ^[previously] attempts (with code).

The principles of Harmonics were discovered by Pythagoras c.587-c.507 B.C. during travels to Egypt and throughout the ancient world. Hans Kayser made a profound philosophic study of harmonics in the 20th century. Algorithmic composition is the technique of using harmonic algorithms to create music. Drew Lesso has been creating algorithmic music since 1975. Samples like Crystal, Constellations, or Planet Earth demonstrate the math behind the music. Over the years, Lesso has collaborated with many other musicians and poets to create an airy, evolutionary legacy.

Universal Algorithm of Experience: Rev. Luke Anthony Murphy has produced four books of graphs over the past five years: Relationships, Spiritual Matters, Money, and Problems. These graphs are attempts to give shape to the conditions that produce the internal environment of anxiety. Recently a group of these were presented in a show called Wilderness at Bernadette Salvage Fine Arts in conjunction with 7hours in Brooklyn. Rev. Luke Anthony Murphy is a painter and shows this work as well as his digitally produced drawings and photos in New York, Toronto, and Berlin. He currently lives in East Harlem, New York, and works for CBS.com.

Introduced to Western culture by the Beatles in their single Norwegian Wood, the sitar has featured prominently in North Indian classical music for centuries. Princeton-based computer scientist Ajay Kapur updates the instrument with his ESitar, an audio and video controller that uses gesture input (PDF) and machine learning algorithms to facilitate joining the computer with Ajay in his sitar performance. Undergraduate engineering students at the University of Pennsylvania work from the other direction, building RAVI-bot, an award-winning, self-playing robotic sitar (YouTube) programmed to generate music from classical Raga scales and melodies all on its own. For those in the Philadelphia area, be sure to check out a live performance of RAVI-bot at the local Klein Art Gallery.

Algorithmic composition is a method of composing music using basic alogrithm models to compose. Musicalgorithms is a program designed to allow composers a tool to explore algorithmic composition and lay people the opportunity to create music based on non-musical models.

"GoogleSynth uses the Google Image Search thingy to randomly grab two images as the 'input' and 'target' images for the algorithm. Once it has two images it applies the algorithm with the parameters set by the user and produces a new image based on them. The results vary wildly, often the output is a total mess, but it creates some cool looking stuff now and then (depending on your definition of 'cool')." (For Windows and Mac OSX.)
