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.
This document discusses server-side event-driven programming using Node.js. It covers how Node.js uses an event loop and asynchronous non-blocking I/O to handle many connections concurrently with high performance. Common Node.js concepts are explained like first-class functions, callbacks, and event emitters. Node.js is compared to traditional threaded programming and shown to have advantages in scalability and efficiency. Example Node.js applications and APIs are provided.
Node.js is a cross-platform JavaScript runtime environment that allows for building server-side and networking applications. It uses Google's V8 JavaScript engine and supports asynchronous programming which makes it suitable for data-intensive real-time applications that run across distributed devices. Some key advantages are that it is fast, supports many concurrent connections, and has a large ecosystem of libraries available through npm. However, it is still maturing and relies on JavaScript.
Node.js is a JavaScript runtime built on Chrome's V8 engine that uses asynchronous and event-driven programming to build fast and scalable network applications. It allows for non-blocking I/O operations through a callback pattern to prevent slow operations from blocking other operations. Node.js uses a single thread event loop model that handles concurrent operations without blocking. It can be used to build HTTP servers, watch files for changes, interface with databases like MongoDB, and create real-time web applications using web sockets. Node.js is well suited for real-time applications, APIs, and streaming but not for CPU intensive or data transformation tasks.
The next generation JavaScript doesn't need to dependent on browser, that's just like other programming language. Node.js is it, no need browser, based on fastest V8 JavaScript Engine and provides many APIs for system integration. It can be used to server-side and system, even more purpose.
A brief overview of server side JavaScript usage focused on NodeJS.

Introduction to performance tuning perl web applicationsPerrin Harkins
This document provides an introduction to performance tuning Perl web applications. It discusses identifying performance bottlenecks, benchmarking tools like ab and httperf to measure performance, profiling tools like Devel::NYTProf to find where time is spent, common causes of slowness like inefficient database queries and lack of caching, and approaches for improvement like query optimization, caching, and infrastructure changes. The key messages are that performance issues are best identified through measurement and profiling, database queries are often the main culprit, and caching can help but adds complexity.
ServiceWorker: New game changer is coming!Chang W. Doh
I believe ServiceWorker is one of most important specifications for the next web world. Offline and its technologies are very friendly concepts to native application developers. But, now I think front-end developers have to know that for stepping into new paradigm. With ServiceWorker, you can make your web application can run offline, and it also means you can make your web application load extremely fast.
I've told about ServiceWorker very briefly in this slide. But you can understand how ServiceWorker runs on. If you want to know its usage, I highly recommend Topeka, which is a polymer demo application at google I/O 2014, that also includes material design and ServiceWorker in inside of it.
If you want to know ServiceWorker some more or in detail, I'd like to recommend to read the following, written by Jungkee Song, one of authors of this spec.

EISA is a new programming language targeted towards JavaScript that is designed for asynchronous and interactive development. It addresses key problems with asynchronous programming in JavaScript like nested callbacks and broken code locality. In EISA, asynchronous tasks can be defined sequentially using async/await rather than nested callbacks. This was demonstrated with a 3D scene loading example where the entire workflow was defined asynchronously without nested functions. EISA originated from game development needs but can now be used for general purposes. It focuses on providing an optimized syntax for domain-specific languages while remaining compatible with JavaScript.
Node.js is a JavaScript runtime environment for building fast and scalable network applications. It uses non-blocking I/O and event-driven architecture, allowing it to handle multiple connections simultaneously without blocking. This makes Node.js suitable for real-time web applications with many simultaneous connections. Node.js has a small core but is extensible through modules. Common modules include Express for building web servers and Socket.IO for real-time web functionality. While Node.js is well-suited for I/O-intensive applications, it is less suitable for CPU-intensive or memory-intensive applications due to its single-threaded nature.
This document provides an introduction to Node.js. It discusses that Node.js is an event-driven, non-blocking I/O platform for building scalable network applications using JavaScript. It was created to address issues with traditional blocking I/O by using asynchronous programming. The document outlines benefits of Node.js like using JavaScript for server-side applications, non-blocking I/O, a large module ecosystem, and an active community. It also provides examples of core modules, writing simple modules, and creating an HTTP server in Node.js.
The SPDY Protocol is likely going to be the successor of http. This short talk summarizes the most important points and includes a demo on how to migrate a Wordpress blog on httpd.
This document summarizes configuration management tools and introduces Ansible. It notes that Puppet and bcfg2 are pull-based with custom authentication and performance issues, while Ansible is push-based using SSH keys, fast with no daemons. Ansible can be installed with pip and used immediately in one-shot mode or with playbooks for complete configuration management. Playbooks allow defining collections of actions like one-shot mode with notifications. The document concludes that Ansible can go from zero to production in minutes with no custom setup or dependencies.
The document introduces CouchApp, a tool that helps organize CouchDB applications. CouchApp generates application skeletons and provides libraries for frontend development. It also helps manage design documents through its deployment process. However, CouchApp may not be suitable for all applications and is better suited for smaller single-page applications where business logic is not massive. Larger sites can become hard to maintain with only CouchApp's rudimentary tool support.
This document discusses various tools for rapidly provisioning development environments including Packer, Vagrant, Puppet, Chef, Ansible, Salt, and Docker. It compares the tools and highlights features like infrastructure as code, declarative configuration, provisioning, and ready-to-go images. It also discusses using these tools together in a continuous integration/deployment pipeline with tools like Jenkins.
The document discusses Concurrency-oriented Programming (COP) using Erlang. It explains how Erlang programs work using lightweight processes that communicate asynchronously via message passing. This allows for high performance, reliability, and scalability. It provides examples of stateless server processes and using CouchDB for schema-free document storage accessible via REST APIs. Ruby libraries for interacting with CouchDB are also mentioned.
The document discusses the technology stack used at skypicker.com, including their use of uWSGI to serve Python applications for features like booking flights. It describes how uWSGI provides benefits like high performance, flexibility to run on multiple web servers, and abilities like shared memory and managing worker processes. It also compares uWSGI's performance to alternatives like using the Python dictionary or Redis for shared memory.
This document provides an overview of ExpressJS, a web application framework for Node.js. It discusses using Connect as a middleware framework to build HTTP servers, and how Express builds on Connect by adding functionality like routing, views, and content negotiation. It then covers basic Express app architecture, creating routes, using views with different template engines like Jade, passing data to views, and some advanced topics like cookies, sessions, and authentication.
The document provides an overview of Node.js, a JavaScript runtime environment for building scalable network applications. Some key points covered include:
- Node.js is built on Google's V8 JavaScript engine and is event-driven and non-blocking.
- It is well-suited for data-intensive real-time applications due to its lightweight and efficient nature.
- Node.js differs from other scripting languages by being non-blocking, single-threaded, and having an event-based approach built-in.
This document discusses techniques for improving frontend performance. It recommends making fewer HTTP requests, using a content delivery network, adding expiration headers, gzipping components, optimizing stylesheet and script placement, avoiding redirects and duplicate scripts, and more. It also covers techniques for loading scripts asynchronously without blocking page rendering, such as using script elements, XHR, and iframes. Faster page loads can improve user experience and increase revenue.
JavaScript performance patterns focuses on optimizing JavaScript loading and execution for better performance. Some key points include reducing the number of script files, leveraging caching, minification and compression. Asynchronous loading helps prevent blocking. DOM operations are expensive so it's important to cache references, batch operations and avoid reflows. Data attributes provide a convenient way to store data on elements. Shims and polyfills should be used judiciously, loading conditionally where native support is limited. Benchmarking is crucial to identify real bottlenecks and measure impact of optimizations.

En introduktion till arkitektur och arkitekturrollens plats i en agil miljö.
Presentation gavs under NFIs konferens Systemförvaltning 2013, onsdag 4 december.
This document discusses coding dojos, which are sessions where developers practice and learn coding skills together. The document outlines several key points about coding dojos, including that they provide a safe learning environment where developers can practice skills important for their work in a production-like setting. Coding dojos emphasize learning by doing through repetition of exercises or "katas". Different styles of conducting dojos are discussed, such as presentations, random pairing of developers, and breaking into groups. The document also covers potential skills developers may gain from dojos and how dojos can positively impact company culture.
The document discusses clean code principles such as writing code for readability by other programmers, using meaningful names, following the DRY principle of not repeating yourself, and focusing on writing code that is maintainable and changeable. It provides examples of clean code versus less clean code and emphasizes that code is written primarily for human consumption by other programmers, not for computers. The document also discusses principles like the Single Responsibility Principle and the Boy Scout Rule of leaving the code cleaner than how you found it. It questions how to measure clean code and emphasizes the importance of writing tests for code and refactoring legacy code without tests.
This document discusses test-driven development (TDD) and its benefits. It notes that TDD can find bugs earlier and reduce costs, though traditional testing is still needed. TDD involves writing a test first, then code to pass the test, and refactoring code while ensuring all tests remain passing. Practicing TDD through coding "katas" or exercises in a "dojo" setting can improve skills over time through repetition. While TDD takes more initial time, the benefits are more confidence, productivity, reliability and agility in the long run.
The document discusses several agile concepts including the Agile Manifesto, Scrum, Extreme Programming (XP), Test-Driven Development (TDD), and coding dojos. It outlines the values and principles of the Agile Manifesto which emphasize individuals, interactions, working software, customer collaboration, and responding to change. It then provides brief descriptions of Scrum roles, ceremonies, and artifacts as well as XP practices like pair programming, writing unit tests first, and integrating often.
The document discusses principles and best practices for writing clean code, including writing small, focused functions; writing code according to the "red, green, refactor" process; using intention-revealing names; following the DRY principle to avoid duplicated code; applying the single responsibility principle and Law of Demeter for loose coupling; and writing tests. It also references concepts like the Boy Scout Rule and emphasizes code quality through maintainability and readability.
This document provides an overview of how to use Mockito to create mock objects and define their behavior in tests.

HCL Nomad Web is heralded as the next generation of the HCL Notes client, offering numerous advantages such as eliminating the need for packaging, distribution, and installation. Nomad Web client upgrades will be installed “automatically” in the background. This significantly reduces the administrative footprint compared to traditional HCL Notes clients. However, troubleshooting issues in Nomad Web present unique challenges compared to the Notes client.
Join Christoph and Marc as they demonstrate how to simplify the troubleshooting process in HCL Nomad Web, ensuring a smoother and more efficient user experience.
In this webinar, we will explore effective strategies for diagnosing and resolving common problems in HCL Nomad Web, including
- Accessing the console
- Locating and interpreting log files
- Accessing the data folder within the browser’s cache (using OPFS)
- Understand the difference between single- and multi-user scenarios
- Utilizing Client Clocking
