React (or React Js) is a declarative, component-based JS library to build SPA(single page applications) which was created by Jordan Walke, a software engineer at Facebook. It is flexible and can be used in a variety of projects.
Plain React detects changes by re-rendering your whole UI into a virtual DOM and then comparing it to the old version. Whatever changed, gets patched to the real DOM.

State is managed within the component in which variables declared in function body. State can be changed. State can be accessed using “useState” Hook in functional components and “this.state” in class components. Hook is a new feature in react. To use this expression it’s essential to have good understanding of class components. State hold information that used for UI by browser.

Donada d’elevada dispersió dels habitants al Berguedà es va decidir que el més eficient era centralitzar el cribratge de retinopatia diabètica en el nucli urbà de més població, Berga i instal•lar allà la càmera no midriàtica tot creant una consulta de cribratge ocular integral (fons d’ull amb càmera no midriàtica, tonometria i agudesa visual) per als pacients amb diabetis mellitus. Per realitzar la lectura de les fotografies de la càmera no midriàtica es va creure que aquesta funció podia ser assumida per facultatius dels equips d’atenció primària sota la supervisió de l’oftalmòleg de l’Hospital de Berga. Les imatges de fons d’ull, la tonometria i el resultat de l’agudesa visual han estat valorades per facultatius lectors que setmanalment han informat dels resultats utilitzant el programa eCAP. Mensualment s’han reunit els lectors amb l’oftalmòleg per parlar de les imatges dubtoses. Aquells pacients amb imatges, tonometria o agudesa visual patològiques han estat derivats al Servei d´Oftalmologia de l’Hospital. Entre l’agost de 2010 i el febrer de 2011 s’han realitzat un total de 424 lectures de fotografies de càmera no midriàtica

2018 02-22 React, Redux & Building Applications that Scale | ReactCodifly
We are grateful for VTK and Ugent for having us in their auditorium in Ghent for a meetup on react, redux and building applications that scale.
Our speaker of the evening was Kristof Van Miegem, co-founder of Codifly (http://codifly.be/). He explained how to manage application state in React applications with Redux, followed by a focus on immutable data structures and how these data structures fit perfectly into this story.
React is a different way to write JavaScript apps. When it was introduced at JSConf US in May, the audience was shocked by some of its design principles. One sarcastic tweet from an audience member ended up describing React’s philosophy quite accurately: https://twitter.com/cowboy/status/339858717451362304
We’re trying to push the limits of what’s possible on the web with React. My talk will start with a brief introduction to the framework, and then dive into three controversial topics: Throwing out the notion of templates and building views with JavaScript, “re-rendering” your entire application when your data changes, and a lightweight implementation of the DOM and events.
Flux architecture and Redux - theory, context and practiceJakub Kocikowski
Flux Architecture changes how we think about data in frontend applications. In the talk I will cover the theory — what Flux Architecture is, what are the driving principles behind it and how it compares to other patterns in software developer landscape. And practice — what implementation decisions made Redux the most popular implementation of the pattern and do you need Redux to use Flux in your project.
And finally I will try to answer the most important question: when will Flux add value to your project and when it just adds unnecessary complexity?
Container orchestration from theory to practiceDocker, Inc.
"Join Laura Frank and Stephen Day as they explain and examine technical concepts behind container orchestration systems, like distributed consensus, object models, and node topology. These concepts build the foundation of every modern orchestration system, and each technical explanation will be illustrated using SwarmKit and Kubernetes as a real-world example. Gain a deeper understanding of how orchestration systems work in practice and walk away with more insights into your production applications."

Speaker: Jyoti Puri
In this webinar, we take a look at React JS and how it’s more than a simple JS library. The speaker takes us through the fundamentals of react, and sheds some light on how it solves the challenges faced in current web application development.
The session covers the React philosophy, components, virtual DOMs in React, reliability improvements and a lot more. Stay tuned for the live Q/A at the end, which also clarifies a lot of issues regarding parent and child components, rendering, and the various use cases, advantages and limitations of React.
(IMPROVED VERSION FROM GEECON)
How can we quickly tell what an application is about? How can we quickly tell what it does? How can we distinguish business concepts from architecture clutter? How can we quickly find the code we want to change? How can we instinctively know where to add code for new features? Purely looking at unit tests is either not possible or too painful. Looking at higher-level tests can take a long time and still not give us the answers we need. For years, we have all struggled to design and structure projects that reflect the business domain.
In this talk Sandro will be sharing how he designed the last application he worked on, twisting a few concepts from Domain-Driven Design, properly applying MVC, borrowing concepts from CQRS, and structuring packages in non-conventional ways. Sandro will also be touching on SOLID principles, Agile incremental design, modularisation, and testing. By iteratively modifying the project structure to better model the application requirements, he has come up with a design style that helps developers create maintainable and domain-oriented software.
Elm - Could this be the Future of Web Dev?David Hoerster
As a developer who enjoys building concurrent and distributed applications, dealing with the front end has never been a favorite task. And I have often thought that building front-end applications by mixing logic into HTML tags has never felt right. What if I could build my web app using a more unified language and approach? Well, enter Elm, a functional language that transpiles to JavaScript while providing static type checking. In this session, we'll take a look at what Elm provides, how its simple Model-Update-View architecture can bring a lot of power to your applications, and we'll walk through a simple SPA demo in order to provide you a taste of what Elm can provide. At the end of this session, you'll have a better understanding of Elm's approach to web application development and be equipped to build your own Elm applications.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
