What is React?
curl
https://github.com/facebook/react/blob/master/README.md

Interest in React
• xhp is not adopted
• released one year ago
• Facebook, Instagram, Airbnb, Khan Academy,
Mozilla, Github, etc.
• New frameworks using React concepts: mithril,
elm, mercury and ractive

“I’ve seen React as the replacement for the
views component of Angular.”
–Tyler Renelle

Getting started
http://facebook.github.io/react/docs/tutorial.html

Rendering
• Rendering everything is conceptually simple
• render() is called every time state/props change
• Naive implementation would be really slow

Best practices
• Minimize state
• Isolate state to a logical place in a component
• Do not mutate the DOM directly.
• Think of components as state machines
• Pass props in one direction, use callbacks

Integration
• Most components should only contain display logic
• Use a root component that does orchestration
• Use another place to do that (`Backbone.Router`)

Existing plugins
• Some lifecycle methods:
componentDidMount()
componentDidUpdate()
componentWillUnmount()
• getDomNode()
• refs

“I also like things about React, which is in some
ways less ambitious because React just says,
“We’re the view. You can use us with Ember or
Angular.””
!
“And the view, there are various ways to skin
that cat and I like the React way of using virtual
DOM diffing and immutability.”
–Brendan Eich

ProtoPie with ElectronScotty Kim

This document discusses ProtoPie, an interaction prototyping tool for designers. It began as various projects - ApplePie used AWS/Azure with AngularJS, BananaPie used Electron and was file-based, and ChocoPie now uses a local server compiled with Enclose and separated from Electron. ChocoPie aims to be a high growth hybrid application toolkit for developers, allowing them to distribute packages across platforms using web skills. It recommends using basic packaging methods for normal apps but protecting commercial sources using a local node.js server and compilation with Enclose.

The Architect WayJan Jongboom

The document discusses modularizing a codebase using Architect, a dependency injection framework for Node.js. It describes problems that can occur when a codebase grows such as tight coupling between modules and lack of configuration options. Architect addresses these by treating each piece of functionality as a plugin that can import other plugins, declares dependencies, and is configured through options. This allows building independent and testable modules that can be combined to create applications.

Erlang - Dive Right Invorn

Erlang is a functional programming language built for reliability and concurrency. It is used to build scalable and fault-tolerant systems through features like its supervision tree, behaviors, and OTP framework. The document recommends learning more about Erlang through various books and online resources, and suggests trying out the build tools rebar and ChicagoBoss or contributing to open source projects like Riak to get hands-on experience with the language.

MunchkinJaewe Heo

1. The document discusses building an app called Munchkin using Electron and React-Photonkit. It describes setting up the app skeleton with different components like a header, sidebar, and viewer. 2. It then covers using IPC to communicate between the main and renderer processes to update device data from ADB in real-time. Methods for sending and receiving IPC messages are demonstrated. 3. Troubleshooting resolving the Electron module is discussed, along with ensuring the proper webpack configuration is set up for an Electron target.

React, London JS Meetup, 11 Aug 2015Stuart Harris

React is a revolution in web UI technology that uses a virtual DOM for fast rendering. It allows developers to build user interfaces as components in a declarative way using JavaScript or JSX. Components are fast, stateless, and their UI is a projection of data. The virtual DOM diffing algorithm efficiently detects changes and updates the real DOM. React promotes building user interfaces with unidirectional data flow and separating concerns into components rather than MVC.

STAQ Development Manual (Redacted)Mike Subelsky

This deck represents our current thinking about the best way to build enterprise SaaS software in 2015 - using a variety of techniques from several disciplines. Since I wrote this I have also become very interested in resilience engineering and the notion that web developers are primarily engaged in the construction of socio-technical systems. When I rewrite this I plan to talk about how we should try to minimize mean-time-to-recover (MTTR) instead of mean-time-between-failures (MTBF), and how continuous deployment grows a safety culture around your operations. I redacted most of the examples that illustrate these points because they use sensitive code examples or URLs. If you want to see the rest of slides, join us!

However, it notes that the pull request cycle can be a potential downside.

Ruby Concurrency RealitiesMike Subelsky

This document discusses different approaches to concurrency in Ruby including processes, threads, actors, fibers, and events. Processes provide simple concurrency but require starting each process and can't share resources. Threads provide concurrency within a process but require careful use to avoid bugs. Actors and fibers provide lightweight concurrency models based on message passing. Events provide high-performance concurrency using an event loop but code can become complex. The best approach depends on specific needs and runtime.

introduction to the document object model- Dom chapter5FLYMAN TECHNOLOGY LIMITED

This chapter introduces the Document Object Model (DOM) which allows JavaScript to access and manipulate elements of a web page without reloading. It discusses how the DOM represents each element as an object, and how this enables dynamic effects like animations. It also covers how the Image object can be used to dynamically change images and create simple animations by modifying src attributes over time. Caching images in memory rather than redownloading them each time improves performance.

Defensive Programming 2013-03-18Laura A Schild

Components are used to build up the UI and can contain state that updates the view on change. - The Flux architecture is described using React with unidirectional data flow from Actions to Stores to Views via a Dispatcher. This ensures state changes in a predictable way. - Setting up React with tools like Browserify/Webpack for module bundling is discussed, along with additional topics like PropTypes, mixins, server-side rendering and React Native.

Learning React - IMitch Chen

This document provides an overview and introduction to React, a JavaScript library for building user interfaces. It first showcases popular sites that use React like Facebook and Instagram. It then defines React as a library for creating user interfaces that renders UI and responds to events. The key benefits of React are that it is battle-tested, supports large applications with changing data over time, and uses encapsulated components to make code reuse, testing and separation of concerns easy. Components are the fundamental building blocks of React, and are reusable, composable units. When state changes, React re-renders the entire component efficiently by maintaining a virtual DOM to compute minimal DOM updates. The document concludes by pointing to additional React topics and a sample tutorial.

React jsJai Santhosh

This document introduces React, describing it as a JavaScript library for building user interfaces by rendering components rather than mutating the DOM directly. It discusses how React uses a virtual DOM for fast re-rendering, building components instead of templates, and the use of JSX syntax to write HTML-like code. Components have state and props, and the whole app re-renders when state changes to guarantee updates.

React in Native Apps - Meetup React - 20150409Minko3D

Minko is a platform to display, share and interact with 3D content from anywhere, whether you're on a web browser, a workstation, or a device that fits in your pocket. In order to reach those targets with the team we have, we had to go with a cross-platform, hybrid solution that would enable fast UI development with native 3D performances. So we built one, on top of many open source projects, using C++. This talk will discuss our approach for building cross-platform HTML5 interfaces, with a C++/JS bridge to bind DOM APIs, and the tricks we use to make them responsive (spoiler: React is one of them).

Introduce Flux & react in practices (KKBOX)Hsuan Fu Lien

Flux is an application architecture pattern for building user interfaces that uses unidirectional data flow. React is a view library that handles the visual DOM and component lifecycle. Flux uses a dispatcher to facilitate one-way data flow from the actions to stores to views. Stores hold the application state and trigger changes that cause React components to re-render. Together, Flux architecture and React components allow building large web applications in a predictable and performant way.

React.js - and how it changed our thinking about UIMarcin Grzywaczewski

This document discusses React.js and how it changed the author's thinking about building user interfaces (UI). It describes how developing UI was previously slow, error-prone, and not fun using Handlebars templates, jQuery DOM manipulation, and redrawing on every change. React.js introduced a declarative and component-based approach that is faster, less error-prone, and more enjoyable. Components have properties (props) and state, re-render only when needed for performance, and can be reused and remain independent. This new approach to UI development freed the author to focus more on experimentation rather than fighting the framework.

Promoter – A Python Project for Replicating a JSS via the APImacbrained

This document summarizes the development of a Python module called "promoter" that was created to migrate objects like policies between Jamf Pro servers. The original goal was to script the manual process of promoting a policy from a test to production environment. Early versions had limitations due to API restrictions. The current version uses "manifests" - dictionaries that define actions to take on an object's XML - to manipulate objects and replicate a production environment. While more work remains, promoter aims to automate the migration of individual objects and handle dependencies between objects. The full module will eventually be available on GitHub.

Kevin Whinnery: Write Better JavaScriptAxway Appcelerator

One of the main reasons Titanium Mobile has been so successful is that the technology has significantly lowered the barrier to entry for native mobile development. A major force behind this is JavaScript, Titanium's primary programming language. The JavaScript programming language is small enough where the basics can be learned in a matter of hours, which has enabled developers from many different backgrounds to become productive using Titanium. But there's much more to JavaScript than just control structures and a handful of primitive data types - JavaScript is a beautiful functional programming language with great features you might not be using. Most developers working on the web today have had some exposure to JavaScript, but there's a difference between using jQuery for DOM manipulation on a web page and writing an entire application in JavaScript. This talk, intended for beginner or intermediate JavaScript developers, will focus on the essential language features you will need to write professional JavaScript applications, including but not limited to: Object Oriented Programming in JavaScript The Good Parts and Bad Parts of JavaScript Useful JavaScript Patterns, Tricks, and Style Guidelines The JavaScript runtime in Titanium Mobile Further Reading and ways to stay up to date on JavaScript

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

How analogue intelligence complements AIPaul Rowe

Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results. News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.
