Node.js: CAMTA Presentation

The document discusses the future of server-side JavaScript. It covers various Node.js frameworks and libraries that support both synchronous and asynchronous programming styles. CommonJS aims to provide interoperability across platforms by implementing synchronous proposals using fibers. Examples demonstrate how CommonJS allows for synchronous-like code while maintaining asynchronous behavior under the hood. Benchmarks show it has comparable performance to Node.js. The author advocates for toolkits over frameworks and continuing development of common standards and packages.

This is the Async / Await feature added to .NET in .NET 4.5, specifically...Everything I Wish I Knew When I Started Using It! By avoiding the client side discussions around the UI and parallel processing, we can focus on the environment in which most of us live and have both an introduction and deeper dive into how it all works. This is about how we can all use the feature RIGHT NOW to write better performing code.

Perl XS is notoriously ugly, but it's also useful. The dirt can be swept under the carpet to a large

Node has revolutionized modern runtimes. Their async by default strategy boasts 3x the throughput of Java. And yet, the language runs 5x slower than C++ (when JS is interpreted). This talk is an advanced intro into the world of Node where we take a closer look under the hood. What's the event loop? Why are there multiple compilers for JS in Node/V8? How many threads are actually used in Node and for what purpose? We'll answer these questions and more as we go over libuv, v8, the node core library, npm, and more. If you're developing with Node, want to start, or are just curious about how it works, please check it out!

The document discusses asynchronous programming using async and await in C#. It begins by explaining what asynchronous programming is and why it is useful for improving app responsiveness and simplifying asynchronous code. It then describes how async and await works by generating state machines and using continuation tasks. The document covers some gotchas with async code as well as best practices like naming conventions. It provides references for further reading on asynchronous patterns, tasks, and unit testing asynchronous code.

This document discusses options for building real-time web applications with Symfony. It covers existing solutions like ReactPHP, Ratchet, Faye and Pusher that provide real-time functionality. It also considers factors like programming language, application functionality, architecture, and whether to use a self-hosted or hosted solution. Example architectures are presented using Symfony with Ratchet and Faye. The document aims to help developers choose the right real-time solution for their needs.

Presentation given at SoCal .NET Architecture group in March 2015. We introduced the async/await keywords and discussed architectural considerations: like why async may be superior to Parallel.ForEach and other parallel options, especially for server-side scaling

This document provides an introduction to Node.js, a framework for building scalable server-side applications with asynchronous JavaScript. It discusses what Node.js is, how it uses non-blocking I/O and events to avoid wasting CPU cycles, and how external Node modules help create a full JavaScript stack. Examples are given of using Node modules like Express for building RESTful APIs and Socket.IO for implementing real-time features like chat. Best practices, limitations, debugging techniques and references are also covered.

This document discusses asynchronous programming using async/await in C#. It covers why multithreading is important, how to use async/await to offload work or scale applications, and how to properly structure asynchronous code. The key points are: async/await provides an easier way to write multithreaded code compared to previous approaches; methods should be marked async if they use await; and tasks can be used to start asynchronous work and wait for completion in a non-blocking way.

DaNode is a simple and small web server written in D that allows running websites using any programming language as CGI scripts. It has fewer than 2000 lines of code, runs on Windows, Linux, and ARM, and allows serving multiple secure domains from a single server using SSL and SNI. While simple and useful for quick tasks, it does not fully implement web standards and its security has limitations, but it serves as a basis for further development and adding features from other frameworks like vibe.d.

This document introduces Reactive Programming with RxJava and how it can be used to create non-blocking applications. It discusses the limitations of blocking code and how RxJava uses Observables and Subscribers to implement reactive and asynchronous operations. It provides examples of converting blocking servlets and HTTP calls to non-blocking using RxJava. While non-blocking code is not always faster, it allows asynchronous operations to utilize threads more efficiently.

This document discusses Node.js architecture and how software lives in hardware. It notes that Node.js uses a single-threaded, event loop model to avoid context switching and blocking I/O. This allows high throughput for operations like HTTP requests but is not optimal for long-running computations in a single thread. The document also addresses issues like callback hell and scaling event emitters, providing solutions like using promises and external queue systems. It concludes by stating Node.js is best for I/O operations, not all problems, and event loop models have existed in other frameworks before Node.js.

Ruby is considered by many to be slow and unscalable. In this talk we’ll try to disprove this premise by introducing EventMachine. We will cover the basic concepts of evented I/O programming and the Reactor pattern. Talk about best practices and useful libraries for EventMachine and see how to test your event driven code. Code examples from the presentation can be found at: https://github.com/omerisimo/em_underground

Hooray, open source Swift finally arrived on Linux in December. Let’s see how easy it is to use Swift for your backend and why Swift is a good choice for safe and fast development.

Actor Programming is a software building approach that lets you can go beyond fault tolerance and achieve Resilience, which is the capacity of a system to self-heal and spring back into a fresh shape. First I'll introduce the difference between Reactive Programming and Reactive Systems, and then we'll go over a couple of implementation examples using Scala and Akka. The coupled GitHub repository with the code is here: https://github.com/ticofab/ActorDemo

This document discusses C# 5's new async and await keywords for asynchronous programming. It begins with an overview of concurrency vs asynchrony, then demonstrates converting synchronous code to asynchronous code using async and await. Key points include using await to wait for asynchronous operations to complete without blocking threads, and assigning continuations to be invoked after asynchronous operations complete. The document also discusses best practices for implementing cancellation and progress reporting in asynchronous methods.

This document provides an introduction to Node.js. It discusses why JavaScript can be strange, but explains that JavaScript is relevant as the language of the web. It then discusses what Node.js is and its event-driven, non-blocking architecture. Popular Node.js applications like HTTP servers, REST APIs, and web sockets are mentioned. Examples are provided of building a simple web app with Express and Jade, a REST API with Restify, and using web sockets with Socket.io. The document also discusses using Mongoose with MongoDB for data modeling.

This document discusses asynchronous I/O in NodeJS. It begins by covering traditional control flow models like single-threaded and multi-threaded processes. It then introduces emerging models like coroutines, fibers, and event-driven non-blocking I/O. The rest of the document focuses on how NodeJS implements an asynchronous event-driven model using libev, libeio, and callbacks. It notes some issues with callbacks and introduces flow control libraries like Steps that help address these issues.

As presented at CodeMotion Tel Aviv: Facing tens of millions of clients continuously downloading binaries from its repositories, JFrog decided to offer an OSS client that natively supports these downloads. This session shares the main challenges of developing a highly concurrent, resumable, async download library on top of an Apache HTTP client. It also covers other libraries JFrog tested and why it decided to reinvent the wheel. Consider yourself forewarned: lots of HTTP internals, NIO, and concurrency ahead!

Node.js is an exciting new platform developed by Ryan Dahl that allows JavaScript developers to create extremely high performance servers by leveraging Google's V8 JavaScript engine and asynchronous I/O. It uses a non-blocking I/O model that makes it lightweight and efficient, as well as features like CommonJS modules and the npm package manager. The document provides examples of building simple HTTP servers and modules in Node.js to demonstrate its capabilities.

This talk was given at the Dutch PHP Conference 2011 and details the use of Comet (aka reverse ajax or ajax push) technologies and the importance of websockets and server-sent events. More information is available at http://joind.in/3237.

Node.js is a JavaScript runtime built on Chrome's V8 engine that is used to develop fast and scalable network applications. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, especially for data-intensive real-time applications that run across distributed devices. Node.js relies heavily on asynchronous event handling, callbacks, and data streams.

Node.js is a platform built on Chrome V8 javascript runtime engine for building fast and scalable, non-blocking, real-time and network applications. In this session I'll introduce you to node.js and developing large code bases using it. We'll cover the following aspects: * What is node.js? * Apache vs. Nginx performance (One thread per connection vs. event loop) and what it has to do with node.js. * Why node was written in Javascript? * Main tools and frameworks (Express, socket.io, mongoose etc.) * TDD/BDD with node.js using mocha and Expect.js
