Firebase Push notifications in React Native Apps
In this post, we’ll learn how to setup Push notification in React Native apps using Firebase. We’ll send notification using Firebase console and receive them in the app. We will also learn how to handle push notifications in your React Native apps. By handling, I mean how to access the data sent via the notification inside your app, and wake your app up if it is asleep or closed. Because all this can get reallllly long, I’ll limit the discussion to Android apps alone. I will post another blog for push in iOS apps in React Native. (Really, the major difference is in setting up the push certificates for iOS app, that’s all) What are Push Notifications How do you know when you get a new message on Whatsapp, Facebook or Twitter, if the app is closed, or even when it is open? Yes, those small messages that pop down from the top of the screen like banners, showing new messages, updates or news are called Push notifications (or simply Push) One might wonder why to integrate Push notifications in an app. Following are the major reasons to use Push in your apps You can read more details of this in rubygarage blog What is React-Native React Native is a JavaScript framework for writing natively rendering mobile applications. It’ is based on React, Facebook’s JavaScript library for building user interfaces, but instead of targeting the browser, it targets mobile platforms. 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. React Native applications render...
Scientists criticize ‘rushed’ approval of Indian COVID-19 vaccine without efficacy data | Science | AAAS
Large amounts of Covishield, one of two vaccines approved in India on 3 January, are stored in a cold room at the Serum Institute of India in Pune. Scientists criticize ‘rushed’ approval of Indian COVID-19 vaccine without efficacy data By Priyanka PullaJan. 5, 2021 , 4:40 AM Reporting for this story was supported by a journalism grant from the Thakur Family Foundation, which has not influenced the contents of this report. India’s drug regulator approved two COVID-19 vaccines on 3 January, a decision Prime Minister Narendra Modi hailed on Twitter as “a decisive turning point to strengthen a spirited fight!” against the pandemic and a testament to the Indian scientific community’s self reliance. But some scientists and patient advocates are sharply critical of the move—in particular, the decision to greenlight Covaxin, a vaccine developed in India by Bharat Biotech, without awaiting the results of a phase III trial to determine efficacy and safety. At a Sunday press conference, the Drugs Controller General of India, V G Somani, said that even though Covaxin’s efficacy study is still recruiting participants, he was approving the vaccine as “abundant precaution,” in case it was needed to curb the spread of a highly transmissible variant of SARS-CoV-2 first found in the United Kingdom. Somani said it and the other vaccine, the Indian version of a vaccine developed by the University of Oxford and AstraZeneca, were approved for “restricted use” in an emergency situation and that their manufacturers would have to continue the clinical trials that have begun. The approval of a vaccine without phase III data is “unconscionable,” says Vineeta Bal, an immunologist at India’s National Institute of...Web Development on an iPad – Laravel News
Web Development on an iPad The idea of working entirely from an iPad has always appealed to me. The portability, the battery life, and of course the touch screen makes it an excellent device. The downside is that everything is sandboxed. You can only run programs from the App Store which makes doing crazy things like installing a development server on the machine unattainable, but there are other ways to work around the limitation with existing apps and a little ingenuity. Last month I had an unfortunate biking accident and broke the bones in the back my left hand. After surgery, they had my middle, ring, and pinkie fingers fused so everything could heal properly, but this meant I couldn’t use that hand for typing. I had to embrace typing one-handed, and I found using an iPad to be the easiest because of the autocomplete and the autocorrect. I was much faster with it than on a MacBook, and that pushed me to want to use it more. With my job, I was able to do all my work except development with the iPad, and I would switch back and forth. Using a traditional computer with my code editor, then the iPad for everything else. This flow quickly became annoying, and I started exploring ways of doing everything on the iPad. Screen Sharing My first idea was to just screen share back to my Mac. Using a screen share would allow me to use all the tools I’m comfortable with and still use the iPad. That idea worked better in theory rather than practice. I couldn’t get the screen...
Mobile App Development – Top Aspects to Consider | Blog by WeblineIndia
Read also : React Native – Build Mobile Apps with Increased Developer Productivity For any business, this is the basic thing that they expect. But if you try to push the development process too hard you will end up spending more down the years. It will cost you more in all terms. However, if you are too much specific about things then chances are more that the development process will get stretched from the expected timeline and this can also badly affect your pockets. Now this is not something you want to happen too. So, it would be better that you come up with a solution that falls in between the two scenarios. No doubt app development timeline may vary based on different projects, still you can try to know the time period by understanding a few things. Some of such factors have been mentioned below.

Palestinian Wins Settlement from Cyber-Security Firm for “Terrorist” Listing – Tikun Olam תיקון עולם
Zaher Birawi, founder of the UK-based Palestine Return Centre זאהר ביראווי, פעיל פלסטיני תושב בריטניה שהשב”כ טען כי הוא “מחבל המשתייך לחמאס”, זכה בניצחון משפטי ושמו הוסר מהרשימה השחורה الناشط الفلسطيني زاهر بيراوي، الذي وصفه الشاباك بإرهابي، فاز المعركة القضائية UK Palestinian activist, Zaher Birawi won a years-long legal battle against cyber-security company, Refinitiv, which maintains a security database called World-Check, used by governments, law enforcement, airlines and others to avert risk or danger to themselves, their citizens, or businesses. It is compiled from numerous sources and designates individuals based on a level of risk they pose. When Birawi and the Palestine Return Center (of which he is former board chair) , found themselves listed, their bank accounts were closed, which prohibited them from engaging in both personal business and the activities of his organization. When an NGO has no funds it cannot pursue its work. Which of course was the intent of those who provided the information used to place him on the list. “Terrorists in Suits,” Israeli Strategic Affairs Ministry report But who provided it? And what evidence did they offer to verify the claims? Well there’s a story. I consulted with an Israeli security source who told me that his agency told Refinitiv that Birawi was “connected” to Hamas. The same claim is made in a lurid document, Terrorists in Suits (Hebrew, page 72), published by the Israeli Strategic Affairs ministry “exposing” the purported ties between Palestinians rights groups and so-called terrorist movements like Hamas. Pro-Israel NGOs like NGO Monitor and UN Watch have also echoed these claims. And Israeli media have dutifully reported what the...
9 Popular GitHub Repos For Every Web Developer – DEV
GitHub is the one-stop-shop for everything related to (web) development these days. Frameworks, demos, collections of all sorts — there’s probably nothing you cannot find on GitHub. However, this huge quantity of things is the problem. There are cool things you’ll probably never hear about, simply because there are so many repositories available. So, once again I’ve decided to bring to you some of the most popular GitHub repositories you should know about, each of them having at least ~30,000 stars. The first repository in this list is Realworld. Its creators call it nothing less than “The Mother of all Demo Apps.” A bold statement, for sure, but I don’t think it’s an exaggeration. Realworld is an exemplary Medium.com clone. But not only that. The repository lets you choose between different front end and back end implementations, which you can happily mix. Vue.js + Node/Express or React /Redux + Rust? They got it! Realworld shows you how the exact same blog app is built on almost any popular language or framework. How awesome is that? You Don’t Know JS Yet This repository is a popular book series by Kyle Simpson who is widely known under his alias, Getify. The books dive deep into the mechanics of JavaScript and cover the following topics: The best thing? It’s completely free to read! It’s definitely one of the best series about JavaScript and it really helped me to understand what JS is really about. Even if you think you know JavaScript well — read the books! You will be surprised, I promise. Airbnb JavaScript Style Guide A mostly reasonable approach to JavaScript....Announcing React Native 0.60 · React Native
After months of hard work from hundreds of contributors, the React Native Core team is proud to announce the release of version 0.60. This release handles significant migrations for both Android and iOS platforms, and many issues are resolved too. This blog post covers the highlights of the release. As always though, refer to the changelog for more detailed information. Finally, thank you contributors for helping us to make this milestone! Focus on Accessibility There have been many improvements to the accessibility APIs, like announceForAccessibility, plus improvements to roles, action support, flags, and more. Accessibility is a complex science, but we hope these improvements make it a bit easier to be an A11Y. Be sure to check React Native Open Source Update June 2019 for more details of these changes. A Fresh Start React Native’s start screen has been updated! Thank you to the many contributors who helped create the new UI. This new “Hello World” will welcome users to the ecosystem in a more friendly, engaging way. AndroidX Support AndroidX is a major step forward in the Android ecosystem, and the old support library artifacts are being deprecated. For 0.60, React Native has been migrated over to AndroidX. This is a breaking change, and your native code and dependencies will need to be migrated as well. With this change, React Native apps will need to begin using AndroidX themselves. They cannot be used side-by-side in one app, so all of the app code and dependency code needs to be using one or the other. While your own native code will need to be migrated by you, @mikehardy, @cawfree,...
Performance Improvements in .NET Core 3.0
Back when we were getting ready to ship .NET Core 2.0, I wrote a blog post exploring some of the many performance improvements that had gone into it. I enjoyed putting it together so much and received such a positive response to the post that I did it again for .NET Core 2.1, a version for which performance was also a significant focus. With //build last week and .NET Core 3.0‘s release now on the horizon, I’m thrilled to have an opportunity to do it again. .NET Core 3.0 has a ton to offer, from Windows Forms and WPF, to single-file executables, to async enumerables, to platform intrinsics, to HTTP/2, to fast JSON reading and writing, to assembly unloadability, to enhanced cryptography, and on and on and on… there is a wealth of new functionality to get excited about. For me, however, performance is the primary feature that makes me excited to go to work in the morning, and there’s a staggering amount of performance goodness in .NET Core 3.0. In this post, we’ll take a tour through some of the many improvements, big and small, that have gone into the .NET Core runtime and core libraries in order to make your apps and services leaner and faster. Setup Benchmark.NET has become the preeminent tool for doing benchmarking of .NET libraries, and so as I did in my 2.1 post, I’ll use Benchmark.NET to demonstrate the improvements. Throughout the post, I’ll include the individual snippets of benchmarks that highlight the particular improvement being discussed. To be able to execute those benchmarks, you can use the following setup: Create a directory named BlogPostBenchmarks. In that...
How to Manage the Cost of a Mobile App Development Project? – ThemeREX
Now that you are aware of the phases of an app development project and the cost associated with them, we can move on to the tips to manage and reduce the cost of your app development project. Note down the essential features It is a good idea to think about the functionality of your app before you start working on it. Understand the problems that you want to solve and list down the features that you want to include in the app. While some of the features and functionalities are easy to implement, others will require considerable effort and money to implement. Since the cost of features varies with projects, it is difficult to put a price tag on them. To build your app without exhausting your entire budget, only include the features that are critical to the functionality of the application. Once you have a Minimum Viable Product (MVP), which contains only the essential elements, you can test it and later add more features as an update. You can also cut the development costs by using pre-built features. For instance, instead of spending your time and money on developing your own push notification functionality, you can simply choose a third-party plugin. Numerous service providers offer these pre-built solutions at a nominal price. Consider the location of the app developer Although, every company and developer charges differently, their cost massively depends on their location. For instance, app developers from North America and Australia charge as much as $150/hour on average. In contrast, developers in Eastern Europe and the Indian subcontinent may cost as low as $30 per hour on...![[100% OFF] IT Security For Absolute Beginners : Cyber Security 101 | SmartyBro](https://old.vinova.sg/wp-content/uploads/2021/03/IT-Security-For-Absolute-Beginners-Cyber-Security-101-400x250.jpg)

China uses big data to select Muslims for arrest in Xinjiang: HRW | China | Al Jazeera
A big-data program in China’s Xinjiang “arbitrarily selects” Muslims for detention, flagging behaviour such as wearing a veil, studying the Quran or going on the Hajj pilgrimage as reasons for arrest, according to Human Rights Watch (HRW). In a new report on Wednesday, the rights group said it analysed a leaked list of more than 2,000 detainees in Xinjiang’s Aksu prefecture and found that the programme – known as the Integrated Joint Operations Platform (IJOP) – also flagged people for their relationships, their communications, their travel histories, or for being related to someone the authorities consider suspicious. “The Aksu List provides further insights into how China’s brutal repression of Xinjiang’s Turkic Muslims is being turbocharged by technology,” said Maya Wang, senior China researcher at HRW. “The Chinese government owes answers to the families of those on the list: Why were they detained, and where are they now?” The United Nations estimates that more than one million Turkic Muslims – most of them ethnic Uighurs – have been detained in camps in far-western Xinjiang. Activists say the purpose of the detention was to “erase the ethnic and religious identities of” Turkic Muslims and ensure their loyalty to the Chinese government. Beijing denies the accusations, describing the camps as vocational training centres to help stamp out “religious extremism” in the troubled province. HRW said the Aksu List – which dates from late 2018 – shows further evidence of the role big data and technology plays in helping officials select targets for “coerced thought transformation”. Earlier this year, campaigners documented how officials in Xinjiang’s Karakax used the IJOP to assess whether an...

Azure Active Directory’s gateway is on .NET Core 3.1!
Azure Active Directory’s gateway service is a reverse proxy that fronts hundreds of services that make up Azure Active Directory (Azure AD). If you’ve used services such as office.com, outlook.com, or xbox.live.com, then you’ve used Azure AD’s gateway. The gateway provides features such as TLS termination, automatic failovers/retries, geo-proximity routing, throttling, and tarpitting to services in Azure AD. The gateway is present in more than 53 Azure datacenters worldwide and serves ~115 Billion requests each day. Up until recently, Azure AD’s gateway was running on .NET Framework 4.6.2. As of September 2020, it’s running on .NET Core 3.1. Motivation for porting to .NET Core The gateway’s scale of execution results in significant consumption of compute resources, which in turn costs money. Finding ways to reduce the cost of executing the service has been a key goal for the team behind it. The buzz around .NET Core’s focus on performance caught our attention, especially since TechEmpower listed ASP.NET Core as one of the fastest web frameworks on the planet. We ran our own benchmarks on gateway prototypes on .NET Core and the results made the decision very easy: we must port our service to .NET Core. Does .NET Core performance translate to real-life cost savings? It absolutely does. In Azure AD gateway’s case, we were able to cut our CPU costs by 50%. The gateway used to run on IIS with .NET Framework 4.6.2. Today, it runs on IIS with .NET Core 3.1. The image below shows that our CPU usage was reduced by half on .NET Core 3.1 compared to .NET Framework 4.6.2 (effectively doubling our throughput). As a...

Increasing cyber-attacks show why stringent cyber-security laws are need of the hour
While large companies and organisations have the capital and the resources to deploy various technologies and solutions, on an individual level, the threat looms large India is likely to have a robust cybersecurity policy soon Dr Reddy’s, BigBasket and now JusPay, there are just a handful of data breach instances that have been reported over the last quarter, and not to mention the ones that we aren’t aware of yet. Surprising it may sound but in 2019, India was amongst world’s top 5 cyber-targeted nations along with US, UK, Singapore and Ukraine wherein it held the top position for three months. A growing economy and also an outsourcing hub, India is on the radar of cybercriminals. “India is among the most cyber-attacked countries in the world and hence it is imperative to have stricter cybersecurity and data protection laws to mitigate data thefts and cybercrimes. With over half a billion internet users and over 1.2 billion mobile accounts, India as a country is a breeding ground for cybercriminals. Several reports have registered that in the first 9 months of 2020 alone, organisations and individuals estimated losses of about $6 trillion due to cyber thefts with organisations deploying the highest level of security also falling susceptible to cyber-attacks. Researches have further predicted that by 2027, over 900 million Indians will have a digital presence and coupling it with the unscrupulous use of personal data and information by service providers, it is vital to implement stringent cybersecurity laws,” says Ram Seethepalli, CEO, Cyberior by Europ Assistance India. While large companies and organisations have the capital and the resources to deploy various...
21 Laravel Tutorials for Learning Laravel in 2021 – Laravel News
2021 is a great time to learn Laravel and improve your knowledge if you’ve been using it. To start the year off we’ve made a list of 21 tutorials on everything from getting started to going deeper with the framework. Getting Started with Laravel Tutorials In this tutorial, you’ll go through building a simple link directory app. It covers everything from planning, setting up your database, Blade views, and more. Join our weekly Laravel newsletter and get this as a free PDF. Laravel Eloquent Laravel Eloquent is an object-relational mapper (ORM) that makes it easy to interact with your database. When using Eloquent, each database table has a corresponding “Model” that is used to interact with that table. In addition to retrieving records from the database table, Eloquent models allow you to insert, update, and delete records from the table as well. At its core Eager Loading, is telling Eloquent that you want to grab a model with specific relationships that way the framework produces a more performant query to grab all the data you will need. By eager loading, you can take many queries down to just one or two. In this tutorial, you’ll set up some example relationships and then walk through how queries change with and without eager loading. If you’ve been working with Laravel for any time, you probably know the standard methods for creating Eloquent Models like make(), create(), update, and save(). Laravel includes some other methods are that also really useful for creating and updating Models that I feel don’t get enough attention. In this tutorial, you’ll learn about some of these additional...
