Node.js

Node.js is an open source, cross-platform runtime environment for server-side and networking applications. Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, Linux, FreeBSD, NonStop and IBM i. Node.js provides an event-driven architecture and a non-blocking I/O API that optimizes an application's throughput and scalability. Node.js is gaining adoption as a server-side platform[4] and is used by Microsoft,[5][6] Yahoo! History[edit] Ryan Dahl, creator of Node.js Node.js was invented in 2009 by Ryan Dahl, and other developers working at Joyent.[17] Node.js was created and first published for Linux use in 2009. Dahl was inspired to create Node.js after seeing a file upload progress bar on Flickr. In June 2011, Microsoft partnered with Joyent to implement a native Windows version of Node.js.[23] The first Node.js build to support Windows was released in July. In January 2014, Schlueter announced Timothy J. Overview[edit] V8[edit]

Introduction to Nodejs (taking javascript to the server-side) - GeexHQ 0inShare Web Technologies so far Remeber those days when we used only the basic features of html to bring texts, images, tables and few other layouts into our webpage, Later CSS came into the picture and created a huge impact or it has actually influenced the way a normal web user-interface is made. After creating webpages & designs using markups and CSS, developers turned their focus onto the data transfer techniques, thats when Ajax came into the picture. Taking Javascript to the server-side As we see there are a lot of evolutions happening with the web, now developers have thought out of the box in making javascript more than just a client side programming language.There has been considerable interest in bringing javascript onto the server side as well, thanks to the CommonJS project. However, Node.js is a bit different from these solutions, because it is event-based rather than thread based. Featuring â€œnodeJsâ€ and to start interactive mode use the command p>

Introducing Linked Data And The Semantic Web Next: Introducing Graph Data What is Linked Data and the Semantic Web and what is all the hype about? Principally, the Semantic Web is a Web 3.0 web technology - a way of linking data between systems or entities that allows for rich, self-describing interrelations of data available across the globe on the web. In essence, it marks a shift in thinking from publishing data in human readable HTML documents to machine readable documents. How Does It Differ From The Web As It Is Today? Today, much of the data we get from the web is delivered to us in the form of web pages - HTML documents that are linked to each other through the use of hyperlinks. Enter Linked Data - Liberating Web Databases From Their Old Chains The web contains lots of information, but typically the raw data itself isn't available - rather only HTML documents constructed from data, if a web site is generated from a database at all. But Where Do I Start? It needn't be complicated.

Why Developers Should Pay Attention to Node.js There's a substantial amount of buzz and enthusiasm right now about Node.js. So what is it, and why should you care about it (well, other than "I said so")? ReadWriteWeb chatted with Javascript developer Guillermo Rauch, co-founder and CTO of LearnBoost in order to get some insights. ReadWriteWeb: So, what is Node.js? ReadWriteWeb: Why should developers care? Rauch: First of all, most web developers are already using jQuery, MooTools, or similar frameworks to leverage JavaScript on the browser. Secondly, thanks to the expressiveness of JavaScript and the concise yet powerful Node.js API, you can build programs that have been typically considered out of reach or too time consuming. And lastly, you won't be alone. ReadWriteWeb: What are the key benefits of Node.js? Rauch: There are several: Fast. ReadWriteWeb: What are some of its drawbacks - and how do you respond to criticisms about Node.js? Rauch: It's incomplete. This is the only problem I see right now. Thanks, Guillermo!

s Python Class - Educational Materials Welcome to Google's Python Class -- this is a free class for people with a little bit of programming experience who want to learn Python. The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience. To get started, the Python sections are linked at the left -- Python Set Up to get Python installed on your machine, Python Introduction for an introduction to the language, and then Python Strings starts the coding material, leading to the first exercise. This material was created by Nick Parlante working in the engEDU group at Google. Tip: Check out the Python Google Code University Forum to ask and answer questions.

Meet Node.js | PeepCode Screencasts for Web Developers and Alpha Geeks Preview Download Free Preview NOTE: The code download has been updated for the latest Node 0.6.10 release and NPM 1.1.1. The Web has seen at least four major advancements in browser technology, about once every five years. Node.js makes it easy to write asynchronous, event-driven applications that serve static, dynamic, and persistent data to clients while using a minimum amount of RAM and CPU time. In this 70-minute Node.js tutorial, you’ll learn to install, use, and understand Node by building a real-time geographical tracking system (live demo). You’ll learn to: Install Node.js (including the latest 0.6.10) Create a basic HTTP server Use built-in and third-party code Organize your code into CommonJS modules Understand and catch errors Build dynamic responses at various URL paths Setup a development environment Configure and use a Websocket server library Write a browser client Publish and subscribe to messages between browser and client Includes a typed transcript.

Google Developers This morning we welcomed 6,000 developers to our 7th annual Google I/O developer conference. The crowd in San Francisco was joined by millions more watching on the livestream and 597 I/O Extended events, in 90+ countries on six continents. We're meeting at an exciting time for Google, and for our developer community. There are now one billion of you around the world who use an Android device. One billion. Today, developers got a preview of our most ambitious Android release yet. But, beyond the mobile phone, many of us are increasingly surrounded by a range of screens throughout the day--at home, at work, in the car, or even on our wrist.

What happened next probably went like this: you asked, “What is it?” and someone (or Google) told you that it was a way to write web servers using JavaScript. If that didn’t scare you away, you might then have asked, “Why would you want to use it?” and the answer might have been along the lines of it taking advantage of non-blocking, event-driven IO to enable high concurrency in long polling or comet-based applications. At which point you stopped asking questions. So here’s how it is, how it’s always been: a browser sends a request to a website. Then there was Ajax. But now think about how you’d go about building a service like FriendFeed, where each user’s feed is updating in real time, all the time. Now think about what that means for a traditional web server like Apache. So what’s the solution?
