Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, especially for real-time web applications with many concurrent connections. The document discusses why Node.js uses an asynchronous and non-blocking model, why JavaScript was chosen as the language, and why the V8 engine is fast. It also explains why Node.js is threadless and memory efficient. Finally, it notes that the Node.js community is very active and creative.
Node.js and How JavaScript is Changing Server Programming Tom Croucher
Node.js is a highly concurrent JavaScript server written on top of the V8 JavaScript runtime. This is awesome for a number of reasons. Firstly Node.js has re-architected some of the core module of V8 to create a server implementation that is non-blocking (similar to other event driven frameworks like Ruby’s Event Machine or Python’s Twisted). Event driven architectures are a natural fit for JavaScript developers because it’s already how the browser works. By using an event driven framework Node is not only intuitive to use but also highly scalable. Tests have shown Node instances running tens of thousands of simultaneous users.
This session will explore the architectural basics of Node.js and how it’s different from blocking server implementations such as PHP, Rail or Java Servlets. We’ll explore some basic examples of creating a simple server, dealing with HTTP requests, etc.
The bigger question is once we have this awesome programming environment, what do we do with it? Node already has a really vibrant collection of modules which provide a range of functionality. Demystifying what’s available is pretty important to actually getting stuff done with Node. Since Node itself is very low level, lot’s of things people expect in web servers aren’t automatically there (for example, request routing). In order to help ease people into using Node this session will look at a range of the best modules for Node.js.

This meetup I will go over all the new and improved features in Node v0.8. There was a lot included in 0.8 so I hope to share some examples of what has been added and how can you use this new stuff in your own node projects.
Topics I covered -
Performance improvements!
Domain Module!
Cluster Module!
Basic API changes
Sails.js is a realtime MVC framework for Node.js that is inspired by some of the best ideas behind Ruby on Rails and realtime frameworks like Meteor.js.
In this presentation I'll overview getting started with Sails.js, its architecture and features, as well as some advice on place to look at when you are getting started.

Building Fast, Modern Web Applications with Node.js and CoffeeScriptroyaldark
The slides for a talk I gave at the Bits & Bytes computer science talk series at the University of Minnesota Morris in October 2013. Video of the talk is available here: http://www.kaltura.com/tiny/4lg1e
This presentation gives a brief overview of why and how many modern websites are built using Node.js and CoffeeScript. Using the plethora of libraries available for Node, I show how to quickly and easily develop a website with automatic server-client syncing which scales and can handle thousands of concurrent connections.
#NoXML: Eliminating XML in Spring Projects - SpringOne 2GX 2015Matt Raible
Many Spring projects exist that leverage XML for their configuration and bean definitions. Most Java web applications use a web.xml to configure their servlets, filters and listeners. This session shows you how you can eliminate XML by configuring your Spring beans with JavaConfig and annotations. It also shows how you can remove your web.xml and configure your web components with Java.
Fast as C: How to Write Really Terrible JavaCharles Nutter
For years we’ve been told that the JVM’s amazing optimizers can take your running code and make it “fast” or “as fast as C++” or “as fast as C”…or sometimes “faster than C”. And yet we don’t often see this happen in practice, due in large part to (good and bad) development patterns that have taken hold in the Java world.
In this talk, we’ll explore the main reasons why Java code rarely runs as fast as C or C++ and how you can write really bad Java code that the JVM will do a better job of optimizing. We’ll take some popular microbenchmarks and burn them to the ground, monitoring JIT logs and assembly dumps along the way.

Server side scripting smack down - Node.js vs PHPMarc Gear
Talk given to the audience at to the PHP London User Group June 2011
Rather than a comparison of the two languages this is actually an introduction to Node.js intended to be from the perspective of someone who already knows quite a bit about PHP, covering and comparing common concepts between the two and explaining differences in approaches.
The talk was given in a pub, after several drinks, do please forgive my lax presentation style.
WebSphere App Server vs JBoss vs WebLogic vs Tomcat (InterConnect 2016)Roman Kharkovski
Presented at InterConnect 2016 in Las Vegas, this presentation provides a view on the differences between WebSphere Application Server and Liberty Profile vs. competitive offerings, such as Apache Tomcat, Red Hat JBoss and Oracle WebLogic. It covers both the technical (feature/function) as well as cost considerations (TCA, TCO).

Developing realtime apps with Drupal and NodeJS drupalcampest
Based on Google's V8 JavaScript engine, NodeJS is a fairly new platform for creating scalable and real-time web applications. I will introduce you to NodeJS internals and ecosystem as well as exaplain why and how you can use Node in your Drupal based projects.
Has the traditional intro to event looped servers (thanks Ryan!) with a couple of examples of why I think node.js is particularly exciting today. Code for the demos can be found at https://github.com/davidpadbury/node-intro.
Node.js is an extremely light weight framework for rapidly developing and deploying next generation web and mobile apps. It enables developers to have full stack development. Not only does it save lines of code, but also saves a lot of time in writing those critical code.
Node.js is built on open source Chrome V8 engine. Its built on top of C++ layer. JS code is compiles into machine code for blazing execution on your machine or server.
This slide gives a jump start and a sneak peak for node.js.

Here's the showdown you've been waiting for: Node.js vs Play Framework. Both are popular open source web frameworks that are built for developer productivity, asynchronous I/O, and the real time web. But which one is easier to learn, test, deploy, debug, and scale? Should you pick Javascript or Scala? The Google v8 engine or the JVM? NPM or Ivy? Grunt or SBT? Two frameworks enter, one framework leaves.
This is the English version of the presentation. For the version with Japanese subtitles, see http://www.slideshare.net/brikis98/nodejs-vs-play-framework-with-japanese-subtitles

35. V8 example
The JavaScript code to access property x from a Point object is:
point.x
In V8, the machine code generated for accessing x is:
# ebx = the point object
cmp [ebx,<hidden class offset>],<cached hidden class>
jne <inline cache miss>
mov eax,[ebx, <cached x offset>]

61. Pau:
People is more open minded than in other programming communities.
There is people coming from ruby, python, c, haskell, java, erlang,
php…
62. Mikeal Rogers:
People using node.js are building stuff. the project seeks to make the
lives better of people building products.
63. Mikeal Rogers:
People using node.js are building stuff. the project seeks to make the
lives better of people building products.
My experience with Python and Ruby is that their primary reason for
working on the project is around with a new language and/or vm. the
people who work on “core” don’t build products and probably never
will.

Node.js is not a language and it doesn’t write it’s own vm. it’s not
attractive to people who don’t care about building stuff with it.
68. Why node.js
Why asynchronous IO?
Never blocking, cpu efficient
Why javascript?
Right and popluar language
Why v8?
Extremely fast VM
Why threadless?
Easy, memory efficient
