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.

Ruby Concurrency Realities
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.
London Atlassian User Group - February 2014
Continuous deployment is causing organisations to rethink how they build and release software. Atlassian Bamboo is rapidly adding features to help with automating deployment, but there are a lot of other practical and organisational issues that need to be addressed when adopting this development model. The Atlassian business-platforms team has been dealing with these issues over the last few months as we transition our order system to continuous deployment. This talk will cover why we adopted this model, some of challenges we encountered, and the approaches and tools we used to overcome them.
One Does Not Simply Walk Into Devops
DevOps is much more than tooling and technical details, it’s first and foremost a cultural and operational shift. This deck was given at www.devopscon.com, and covers some of the principles and best practices preached for by devops thought leaders such as John Allspaw, Jesse Robbins, Adrian Cockroft, Jez Humble and others.
10+ Deploys Per Day: Dev and Ops Cooperation at Flickr
Communications and cooperation between development and operations isn't optional, it's mandatory. Flickr takes the idea of "release early, release often" to an extreme - on a normal day there are 10 full deployments of the site to our servers. This session discusses why this rate of change works so well, and the culture and technology needed to make it possible.
Development, Deployment and Collaboration at Etsy
At Etsy about 150 engineers deploy a single monolithic application more than 60 times a day. This process of deploying small changesets continuously enables us to build up and release robust features and detect and fix bugs extremely fast. All while serving over a billion page views per month. Developing and deploying at such a high velocity however only works because product developers and designers, infrastructure and operations engineers and the security team work closely together. We have an extremely open culture of sharing (inside and outside the company) and make sure we run into as few surprises as possible by bringing everybody on the same page about changes.
Continuous Delivery at Wix, Yaniv Even Haim
We will go over the motivations for wix.com R&D to move to a CI/CD/TDD model, how the model was implemented and the impact on Wix R&D. We will cover the tools used (developed in-house and 3rd party), change in methodologies, what we have learned during the transformation and the unexpected change in working with product and the rest of the company.
Presented in the Continuous Delivery track at DevOps Con Israel 2013
Cloud tools
John McCaffrey gives a presentation on cloud tools for development. He discusses terminology related to hosting and deploying applications. Some hosting options he covers include self-hosting, Amazon Web Services, EngineYard, Heroku, and AppHarbor. John then demonstrates deploying applications to Heroku and monitoring tools. He finishes by discussing collaboration tools like email, chat, screen sharing, and code repositories on services like GitHub.
Continuous Deployment at Etsy: A Tale of Two Approaches
1. Etsy has transitioned from infrequent deployments that took weeks of work and often broke the site, to deploying up to 25 times per day with near effortless deploys.
2. By deploying frequently with small code changes and thorough testing, the probability and severity of degradations is reduced, allowing issues to be detected and resolved quickly.
3. Etsy's continuous deployment approach enables rapid experimentation and improvement through frequent analysis of deployment outcomes and re-examination of assumptions.

Ohoh
OHOH is an iOS social networking app like Meetup.com but for smaller groups. It allows private and group chats, likes, comments, and uses push notifications. The app was originally developed using Objective-C, CocoaPods, AFNetworking, and Parse for push notifications. It has since switched to using Layer for chat functionality due to issues with Firebase and additional chat features. The developer discusses experiences with various technologies used in the app's development.
Mobile CI at Etsy
Etsy uses GitHub Enterprise for code reviews of code committed to their on-premise git repositories. They have over 350 Linux virtual machines called "The Bobs" that are used to build and test code. Etsy also has 25 Mac Minis that are used to build, test, and run linting on their mobile Android and iOS code using an automated process with Chef. The summary describes Etsy's implementation of continuous integration for mobile apps using GitHub, Linux VMs, Mac Minis, and automation with Chef to improve testing and visibility of their code.
WTF: Where To Focus when you take over a Drupal project
Jumping into pre-built Drupal projects sometimes requires a leap of faith as much for clients as for developers. The client is usually coming out of a bad previous business relationship and the code is not always structured according to your standards.
During this talk, Symetris will share its experience and provide tips on how to navigate these often uncharted waters. Our goal is to help you convert an uncertain client into a long term partner and have a checklist of what to look out for as developers.

React Native and the future of web technology (Mark Wilcox) - GreeceJS #15
What's all the hype about React Native? What is it? How does it work? Why does it matter and what clues does it give us about the future of web development? Did you know there's a React Native for the Web? What's that all about? It can't be all good, what's wrong with it? Where should you go to find out more?
Webhooks with Azure Functions - Live 360 Conference
Azure Functions make it easy to create and host webhook interfaces without maintaining a server. You can quickly setup an endpoint to receive data and act on it. Being able to ingest, process, and respond to data from a variety of sources without building out an infrastructure gives you time to focus on building functionality.
In this presentation, Nick Zimmerman, Sr. Site Reliability Engineer at SparkPost, will show you how to setup an Azure Function, accept webhook data, process that data with C#, and integrate that data into an application in real time.
DevOps and Performance - Why, How and Best Practices - DevOps Meetup Sydney
DevOps aims to improve collaboration between development and operations teams. When these teams are disconnected, it can lead to severe production issues from a lack of shared understanding and tools. Organizations should strive for agile deployments by implementing continuous integration and deployment pipelines. Pushing changes to production without proper planning, such as failing to optimize critical pages, can also cause problems. Establishing metrics and monitoring across the entire software lifecycle helps align teams and catch issues early.
DevOps: Getting Started with Puppet on Windows
You keep hearing about DevOps and how awesome it is, if you have Linux. Well Windows can be awesome with DevOps, too. And it’s just going to keep getting better. If you are on Windows and you are even remotely interested in making things better, then you should come out and see what Puppet is all about and what it can do for your organization.
OpenStack Israel Summit 2013 - It’s the App, Stupid!
This document discusses the importance of automation and orchestration in deploying and managing applications on platforms like OpenStack. It outlines the different stages in the automation continuum from environment creation to scaling. It then discusses some available tools for each stage, like orchestration tools, configuration management tools, and monitoring tools. Finally, it discusses how tools like AWS OpsWorks provide an integrated solution and compares emerging OpenStack projects like TOSCA, Heat, and Donabe that aim to provide similar orchestration capabilities for application deployment and management.
Using Axe to Add Accessibility Checks to Your Existing Selenium Tests
Accessibility is no longer a nice to have but rather a must have for many applications. Luckily there are things like the W3C’s WCAG (Web Content Accessibility Guidelines) that help testers understand accessibility standards. But wait, it gets better for teams that are using Selenium. This is because adding accessibility checks to your automation is both quick and easy.
In this webinar, Magenic Practice Lead Troy Walsh will show how to leverage Axe, an accessibility testing engine, to add accessibility checks to your existing Selenium test suite. You will see just how easy it is, and be left wondering why it took you so long to get started.
Key Takeaways
- Why accessibility has become a must have for many applications
- How to use the W3C’s Web Content Accessibility Guidelines to understand accessibility standards
- How to easily add accessibility checks to your existing Selenium suite using Axe
The Importance of Culture: Building and Sustaining Effective Engineering Org...
Randy is a 25-year veteran of Silicon Valley, having led engineering organizations at eBay, Google, Oracle, and a number of other companies. Through the lens of his personal experience from hands-on engineer to architect to CTO, at organizations ranging from tiny startups to global giants, Randy will discuss several important aspects of engineering cultures, which both support and hinder the ability to innovate: hiring and retention, ownership and collaboration, quality and discipline, and learning and experimentation.
Randy will suggest some learnings about what has worked well -- and what has not -- in creating and sustaining an effective engineering culture. He will further offer some concrete suggestions on how other organizations -- both large and small -- can evolve their cultures as well.
Pragmatic Continuous Delivery - ReaktorDevDay 2012
The document discusses implementing a pragmatic continuous delivery pipeline for Java applications using open source tools like Jenkins, Nexus, and LiveRebel. The pipeline includes phases for building, testing, QA, and production. Artifacts like WAR files and log files move through the pipeline. While changing processes can be difficult, the presenter suggests automating current workflows and capturing them in a pipeline as a way to introduce continuous delivery practices.
[Christopher Ngo] Intro DevOPS XP Day 2015
This document provides an introduction to DevOps. It defines DevOps as a software development method that stresses communication, collaboration, integration, automation, and measurement between software developers and IT professionals. Traditionally, these groups worked in silos with barriers between development and operations. DevOps aims to break down these silos by having development and operations work more closely together through practices like configuration management, infrastructure automation, deployment automation, and monitoring. This mindset shift and cultural change can provide benefits like improved feedback, collaboration, agility, disaster recovery, and faster testing and deployment. Common DevOps tools include infrastructure as a service providers, virtualization platforms, and containerization tools.

Seller Specific Strategy Report
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Go back-n protocol
Go-Back-N (GBN) is an ARQ protocol that allows a sender to transmit multiple frames before receiving an acknowledgement. The sender maintains a window of size N, meaning it can transmit N frames before waiting for a response. The receiver window is always size 1, acknowledging frames individually. If a frame times out without an ACK, the sender retransmits that frame and all subsequent frames in the window. GBN improves efficiency over stop-and-wait by allowing transmission of multiple frames while reducing waiting time at the sender.

This installation piece was inspired by Ad Reinhardt's black paintings from the 1950s. It comprised swinging lights, chanting voices piped through cylinders, dim lighting, and words broken up on metal wall panels. Lucy Guerin danced in projected images focusing on contorted body movements. The work strived to look beyond the familiar in music, dance, and language. It confirms that historical works can resonate with contemporary works, showing there is no chronology in culture, only the present moment. By breaking conventions, it reflected on Reinhardt's goal of eliminating evidence of personality through chance and negation.

An eoq model with stock dependent demand
This document presents a model of an economic order quantity (EOQ) inventory system where demand is stock dependent and items received contain imperfect quality items. Two cases are considered: 1) imperfect items are sold in a single batch after screening or 2) imperfect items are sold immediately after detection. Approximate optimal solutions are derived for order quantity, cycle time, and expected total profit in each case.

Chapter 4 & 5 Notes
Federalism refers to a system of government where power is divided between national and state governments. The Constitution grants express, implied, and inherent powers to the national government, while reserving other powers for the states. Concurrent powers are shared between the national and state governments. Local governments exercise power granted by their state governments. The Supremacy Clause establishes that the Constitution takes precedence over other laws. The two-party system in the U.S. developed from the Federalists and Anti-Federalists and is maintained by the electoral system and ideological consensus among Americans.

Dev ops lessons learned - Michael Collins
The document discusses lessons learned from trying to implement DevOps in a rapidly growing company. Some key lessons include: (1) being able to clearly articulate what DevOps means for both individuals and the organization; (2) trusting developers and providing them with what they need; and (3) starting DevOps efforts with a focus on development environments rather than just production. The document also emphasizes focusing on toolchains rather than individual tools, using a service delivery pipeline approach, and ensuring good communication and hiring practices.
How to write bad code using C#
There has been lots of talk on the importance of writing good and manageable code – code whose inherent beauty bring tears to the eyes of the developer that looks at it. This talk is not like that. This talk will focus on the techniques that are used by millions across the world to bring tears to the eyes of the maintaining developer, as well as a graphic stream of profanities.We will investigate some of the most common anti-patterns and half-measures that occur in real live code, and will marvel at the ingenuity and outright creativity necessary to create ugly messes of unmaintainable code that still manages to work for it’s users.
Why Plone Will Die
This document discusses reasons why the author believes Plone may decline or become a "CMS zombie" unless changes are made. Key points include:
- Growing developer and integrator frustration due to legacy code, complexities, lack of documentation and APIs.
- Difficult and unpredictable migrations between major Plone versions that introduce issues and costs.
- Stagnating community and market as Plone relies on aging technologies like Zope and ZODB.
The author argues Plone needs to remove legacy code, simplify architectures, introduce explicit APIs, support new databases and Python 3 to thrive in the future. A potential approach is starting from scratch with Pyramid and new components rather than continuing to build on aging foundations.
Going Reactive in the Land of No
Going Reactive in the Land of No or How to build modern reactive systems for the modern
world

Key aspects of the Play Framework are discussed, including its focus on developer productivity, built-in support for RESTful APIs, and stateless and scalable architecture. The presentation concludes with a live coding demonstration of basic Play Framework features.
Introduce Flux & react in practices (KKBOX)
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.
From hello world to goodbye code
At some point, the code you write today will be deleted and replaced with something new. This talk will discuss the life cycle of a large code base, and how to manage it over time to accommodate rewrites, giving examples from a major rewrite of the Firefox build and release pipeline over the last two years. You'll learn how to replace components of a running distributed system while keeping it operational, the proverbial replacing the wing of an airplane in flight.
All about that reactive ui
Slides from my last presentation at the Cape Town Meteor meetup, on optimising the UI, specifically for Hybrid apps and for Meteor JS hybrid apps.

Lean engineering for lean/balanced teams: lessons learned (and still learning...
Bill Scott discusses lessons learned bringing lean principles to engineering at PayPal. Some key points:
1. PayPal moved from a culture of long delivery cycles to prioritizing rapid experimentation and learning from customer feedback.
2. The company established two-pizza teams, used Git for continuous deployment, and made the prototype and production stacks the same to enable fast iteration.
3. Principles for lean engineering include refactoring to support experimentation, designing for volatility, decentralizing work, and establishing a "brain" to guide agile work based on customer needs.
ClojureScript in Magento 2 - MageTitansMCR 2017
This document discusses using ClojureScript to build parts of Magento sites in order to avoid frustration with some of Magento's UI components. It introduces ClojureScript as a hosted LISP dialect that compiles to JavaScript and allows good interoperability with JavaScript code. The author argues that ClojureScript's features like immutability, data structures, and compiler optimizations could help developers build Magento sites more quickly and with better quality. Examples are given of how ClojureScript code interacts with JavaScript in Magento. Recommendations are made for resources to learn more about ClojureScript.
State of Puppet - Puppet Camp Silicon Valley 2014
This document provides an overview of Puppet and Puppet Enterprise, including:
- Puppet's core components like the Puppet language, Facter, Hiera, and MCollective that provide infrastructure automation and management capabilities.
- Puppet Enterprise which builds upon Puppet's open source tools to provide additional features for enterprise customers.
- Related tools like PuppetDB, Razor, and Puppet Forge that provide additional functionality around data storage, provisioning, and community modules.
- Information on getting involved with the Puppet community through training, contributing code/modules, and attending or speaking at events.
React.js - and how it changed our thinking about UI
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.
React Tech Salon
React is a JavaScript library for building user interfaces that aims to solve issues with data changing over time in large web applications. It introduces components, re-rendering on data changes rather than mutating data, and a virtual DOM for efficient re-rendering. React uses a unidirectional data flow and one-way data binding that improves design architecture and code reusability. Related technologies like JSX, Flux, GraphQL, Relay, and React Native further enhance React's capabilities.
REST vs. GraphQL: Critical Look
GraphQL has made an excellent entree on the API scene. It is reintroducing the original concepts of RPC-style architecture with a revolutionary API consumer-oriented approach. It brought a new option to the stalled waters of RESTful APIs. But more importantly, GraphQL brought back the principal question: What is the right API architectural style for my project?
If you are building an API, this talk should give you enough of the theoretical background to make the right API-decision for your product.
In this talk, we will take a critical look at predominant API architectural style – RESTful APIs and put it in contrast to GraphQL and Hypermedia APIs. We will discuss the expected properties of distributed systems, the consequences of choosing a particular API style, and reflect these findings in the pros and cons of the popular methods.
Portable infrastructure with puppet
Portable infrastructure with Puppet can be achieved through Puppet, an open source automation platform created by Puppet Labs to configure and manage infrastructure. Puppet provides a high-level language and reusable modules to standardize infrastructure and reduce maintenance costs. Puppet Labs is working to improve Puppet's performance, features, and usability while expanding its capabilities for infrastructure management and code sharing through new services like the Puppet Forge module repository. The goal is to enable collaboration and reuse of Puppet configurations across organizations through portable modules and tools.
Rapid and Responsive - UX to Prototype with Bootstrap
The document discusses how to rapidly prototype user interfaces using Bootstrap, a popular front-end framework. It outlines the benefits of prototyping with Bootstrap over traditional wireframing or jumping straight to development. Prototyping with Bootstrap allows building interactive prototypes quickly in hours using responsive design principles. The prototypes can then be used as the basis for the final site design rather than being discarded. The document introduces key concepts like responsive design, prototyping, and frameworks. It also provides an overview of features in Bootstrap like grids, components, and how they can be combined for prototyping.

React, London JS Meetup, 11 Aug 2015
- 1. React a revolution in Web UI technology @redbadgerteam
- 2. “strong opinions, which are weakly held” Paul Saffo, Director of Palo Alto’s Institute for the Future
- 3. Give it 5 minutes • He said “Man, give it five minutes.” I asked him what he meant by that? He said, it’s fine to disagree, it’s fine to push back, it’s great to have strong opinions and beliefs, but give my ideas some time to set in before you’re sure you want to argue against them. • https://signalvnoise.com/posts/3124-give-it-five- minutes
- 4. Stuart Harris CIO, Founder Red Badger @stuartharris
- 6. Give it 5 minutes
- 7. Client Server Isomorphic (or Universal) rendering
- 8. Virtual DOM • The DOM is slow, has an imperative API and State • A COMPONENT should be fast, declarative, stateless • “Shared mutable state changing over time is the root of all evil” • A virtual DOM allows you to declare your UI • The UI becomes a projection of your model • Conceptually re-rendered on EVERY change
- 10. f(d) = v f(d’) = v’ diff(v, v’) => changes diff(v’, v) => undo
- 11. WOW • This completely changes the way I think about my application • Very much like immediate mode games rendering • Declarative • Delegated event model
- 12. DEMO
- 13. What about MVC? • Incorrect separation of concerns • Is React the “V” in MVC? • “Components” is a better SoC • What about Web Components? (polymer etc)
- 14. Peter Hunt (Code Winds Podcast) “There is a lot of stuff you get for free when you build like the browser doesn’t exist and this is one thing that distinguishes React from Web Components and Polymer and that kind of thing …they’re getting closer and closer in with the browser, and we’re getting farther and farther from the browser. And I think that our technique is more sustainable in the long term.”
- 15. Render to any surface • react-native • react-art • react-canvas • react-three • Netflix TV • React 0.14 • npm install react@0.14.0-beta1 • npm install react-dom@0.14.0-beta1
- 16. –The Facebook React team “Learn once, write anywhere”
- 17. But it’s only the “View” • Flux • Relay and GraphQL • Om and Om.next • Redux • Arch
- 20. Functional? • Pure render function • shouldComponentUpdate • Immutable data (immutable.js, mori) • Stateless components • Centralised application state
- 21. Tooling • Nuclide • Jest • Atom, Babel (JSX) • Flow • React Dev Tools for Chrome and Firefox
- 22. DEMO
- 23. So where is all this going? • Towards more semantic UI declarations • Separation of UI definition from rendering (0.14) • Multiplatform - learn once write everywhere • More functional
- 24. Stuart Harris CIO, Founder Red Badger @stuartharris
