What Is React Native? by High School Technology Services Myhsts.Org
What is React Native? By High School Technology Services myhsts.org React Native • React Native is a JavaScript framework for writing real, natively rendering mobile applications for iOS and Android. It’s based on React, Facebook’s JavaScript library for building user interfaces, but instead of targeting the browser, it targets mobile platforms. In other words: web developers can now write mobile applications that look and feel truly “native,” all from the comfort of a JavaScript library that we already know and love. Plus, because most of the code you write can be shared between platforms, React Native makes it easy to simultaneously develop for both Android and iOS. Abstracting React from the DOM DOM • Just to get things straight - DOM stands for Document Object Model and is an abstraction of a structured text. For web developers, this text is an HTML code, and the DOM is simply called HTML DOM. Elements of HTML become nodes in the DOM. Cont.. Virtual DOM to abstract react Like the actual DOM, the Virtual DOM is a node tree that lists elements and their attributes and content as objects and properties. React’s render() method creates a node tree from React components and updates this tree in response to mutations in the data model, caused by actions. • Each time the underlying data changes in a React app, a new Virtual DOM representation of the user interface is created • This is where things get interesting. Updating the browser’s DOM is a three-step process in React. • Whenever anything may have changed, the entire UI will be re-rendered in a Virtual DOM representation. -

Ein Analytic-Tool untersucht typischerweise, woher die Besucher kommen, welche Bereiche auf einer Internetseite aufgesucht werden und wie oft und wie lange welche Unterseiten und Kategorien angesehen werden. In Deutschland ist der Einsatz solcher Werkzeuge aus Datenschutzgründen umstritten. Sie wird vor allem zur Optimierung der Website und zur besseren Erreichung von Zielen der Website (z. B. Häufigkeit von Besuchen, Vermehrung von Seitenaufrufen, Bestellungen, Newsletter-Abonnements) eingesetzt. Grundlegend kann bei Web Analytics zwischen Auswertungsverfahren zur permanenten Messung der Site-Effektivität und Methoden zur Auffindung von Schwachpunkten in der Site und Verbesserungsmöglichkeiten unterschieden werden (siehe Methoden). -
Facebook Messenger Engineering
SED 1037 Transcript EPISODE 1037 [INTRODUCTION] [00:00:00] JM: Facebook Messenger is a chat application that millions of people use every day to talk to each other. Over time, Messenger has grown to include group chats, video chats, animations, facial filters, stories and many more features. Messenger is a tool for utility as well as for entertainment. Messengers used on both mobile and desktop, but the size of the mobile application is particularly important. There are many users who are on devices that do not have much storage space. As Messenger has accumulated features, the iOS codebase has grown larger and larger. Several generations of Facebook engineers have rotated through the company with responsibility of working on Facebook Messenger, and that has led to different ways of managing information within the same codebase. The iOS codebase had room for improvement and Project LightSpeed was a project within Facebook that had the goal of making Messenger on iOS much smaller. Mohsen Agsen and is an engineer with Facebook and he joins the show to talk about the process of rewriting the Messenger app. This is a great deep dive into how to rewrite a mission- critical iOS application, and this team became very large at a certain point within Facebook. It's a great story and I hope you enjoy it as well. [SPONSOR MESSAGE] [00:01:27] JM: When I’m building a new product, G2i is the company that I call on to help me find a developer who can build the first version of my product. G2i is a hiring platform run by engineers that matches you with React, React Native, GraphQL and mobile engineers who you can trust. -

Dear Open Source Yearbook reader, The “open source” label was created back in 1998, not long after I got my start in tech publishing [1]. Fast forward to late 2014, when I was thinking about how much open source technologies, commu- nities, and business models have changed since 1998. I realized that there was no easy way—like a yearbook—to thumb through tech history to get a feel for open source. Sure, you can flip through the virtual pages of a Google search and read the “Best of” lists collected by a variety of technical publications and writers, much like you can thumb through newspapers from the 1980s to see the how big we wore our shoulder pads, neon clothing, and hair back then. But neither research method is particularly efficient, nor do they provide snapshots that show diversity within communities and moments of time. The idea behind the Open Source Yearbook is to collaborate with open source communities to collect a diverse range of stories from the year.
