Documentation. New Technique Promises Much Faster Hard Drive Write Speeds. SoundTouch Sound Processing Library. About the SoundTouch library The SoundTouch Library Copyright © Olli Parviainen 2001-2014 SoundTouch is an open-source audio processing library for changing the Tempo, Pitch and Playback Rates of audio streams or audio files Tempo (time stretch): Changes the sound to play at faster or slower tempo than originally without affecting the sound pitch.
Pitch (key) : Changes the sound pitch or key while keeping the original tempo (speed). Playback Rate : Changes both tempo and pitch together as if a vinyl disc was played at different RPM rate. The SoundTouch library is intended for application developers writing sound processing tools that require tempo/pitch control functionality, or just for playing around with the sound effects. The SoundTouch library source kit includes also an example utility SoundStretch that uses SoundTouch library for processing .wav audio files from command-line interface.

Soul Funk Boot - MongoDB Presentations - Using MongoDB with Node.js. Can I use jQuery with node.js. Readme.md at master from guileen/node-mongoskin - GitHub. Node.js and socket.io chat tutorial – ps: it's mike. I found that the ready availability of documentation and the eagerness of experienced individuals to help the newly adopting, throughout the node.js communities, allow for quicker learning and sharing of acquired skills i’ve created a very simple single-room chat client using node.js, socket.io and the express module UPDATE: long overdue, but you can now skip the following step and just install via the .msi or .pkg files and they include NPM – to begin, you must install node.js and npm along with their dependencies cd /pick_a_folder git clone cd node git checkout v0.4.12 #or latest stable version .
/configure make make install #finish nodejs install curl | sh #install npm ok! Now, install the modules npm install -d let’s now create the server file, app.js now, let’s create the client file, index.html run the server node app.js load up in your browser GIT repo UPDATE: i’ve written up a multiroom chat tutorial here. Facebook Connect with Node. Static Version A big part of building a new web application is repurposing common patterns, one such pattern is the ability for users to sign in and out.
God - A Process Monitoring Framework in Ruby. Experimenting with Node.js. If you see extra mouse cursors moving around: don’t worry, they’re part of the demo.
You can always disable them if you want. I’ve written a follow-up on this article, in which I improved a lot of the code. Be sure to read that one too! If you’re using a browser that supports web sockets, you might see some extra mouse cursors moving around. These are actually other people also looking at this page right now, live, as we speak. This is an experiment I did to play around with Node.js and web sockets. Web socket server Using @miksago‘s node-websocket-server made it extremely easy to send and receive messages from a web socket. After including the node-websocket-server library and creating the server, I add some listeners to know when clients disconnect or send a message and make sure messages get sent to the other clients. I saved it as server.js, so starting the server is as simple as running node server.js. Receiving messages As you can see, this connects to the server we just started.
LearnBoost/socket.io-node - GitHub. Mongoose. Add Update: Mongoose 1.0 has been released, and we recommend going to our dedicated website for the most up-to-date information and code At LearnBoost, we like to consider ourselves hackers. We look to implement the best technical solutions for our needs then tell people how we did it and hope they fork our code, contribute and make it even better.
Why MongoDB? While looking into storage solutions we decided that using a NoSQL engine was the best fit for our needs. MongoDB We ended up choosing Mongo for a variety of reasons: commercial support fast Example. MongoDB hosting in the cloud. InMusic. A Short Tutorial on Prolog. This document is an edited version of a Hypercard Stack written by Mike Brayshaw as part of Joint Research Council project ``The Construction and Evaluation of a Prolog Techniques Editor''.

Prolog is a logic language that is particularly suited to programs that involve symbolic or non-numeric computation. For this reason it is a frequently used language in Artificial Intelligence where manipulation of symbols and inference about them is a common task.
Prolog consists of a series of rules and facts. In this tutorial we will introduce some of the central concepts of Prolog under a series of topic headings. Topics. Dependent type. Dependent types add complexity to a type system.
Deciding the equality of dependent types in a program may require computations. If arbitrary values are allowed in dependent types, then deciding type equality may involve deciding whether two arbitrary programs produce the same result; hence type checking may become undecidable. History Dependent types were created to deepen the connection between programming and logic. In 1934, Haskell Curry noticed that the types used in mathematic programming languages followed the same pattern as axioms in propositional logic. Predicate logic is an extension of propositional logic, adding quantifiers. (Because of this and other work by Howard, propositions-as-types is known as the Curry-Howard correspondence.) Formal definition Dependent types can be, very loosely speaking, imagined to be similar to the type of an indexed family of sets.
In a universe of types , one may have a family of types which assigns to each term a type . Or as . For then and. Twelf. Introduction At its simplest, a Twelf program (called a "signature") is a collection of declarations of type families and constants that inhabit those type families.
For example, the following is the standard definition of the natural numbers, with z standing for zero and s the successor operator. nat : type. z : nat. s : nat -> nat. Here nat is a type, and z and s are constant terms. As a dependently-typed system, types can be indexed by terms, which allows the definition of more interesting type families (relations). The constant plus_succ defines the case for when the second argument is the successor of some other number N (see pattern matching). These simple examples do not display LF's higher-order features, nor any of its theorem checking capabilities.
