Flutter vs React Native! Which one to choose?
Today we are in an epoch where we use mobile apps to accomplish everyday responsibilities right from personal to professional goals. When we exist in this digital lifestyle, mobile apps are a demand of more than anything. However, a high performing mobile app is what we require. We have countless mobile applications accessible, and it is a transparent case that only high performing ones are sustaining. When an app does not function well or a user encounters an obnoxious experience, the next step they opt is to download and use another one which serves the same purpose. If the equivalent happens with your app then you will be a hapless victim of dropping a valuable customer. Here comes the point of a high performing app. Determinants like device, speed, loading time, execution, responsiveness, etc. can define the performance, and this performance is crucial to growing your user base. In this situation, we need to think about how to build an app that is high performing and able to resist the ever-changing marketing situation. The best answer is to develop a cross-platform mobile app. In today’s article, we will examine and discover the advantages of one over the other in the case of Flutter and React Native. With these correlations, you can find out which framework suits your necessities both in developing an app or renovating an existing one. React Native Flutter Which is the best? The cross-platform nature of both React Native and Flutter reduces time-to-market. Plus, their third-party libraries and ready-to-use components make it more economical to use them to build your app. So in short we can...

Cyber Security Today, March 17, 2021 – FBI warning on ransomware, how the pandemic has affected IT security and a new botnet threat | IT World Canada News
FBI warning on ransomware, how the pandemic has affected IT security and a new botnet threat. Welcome to Cyber Security Today. It’s Wednesday March 17. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. The FBI has issued a flash alert, warning of increased ransomware attacks on schools, colleges, seminaries and universities in the United States and the U.K. The gang behind this string of attacks will copy data from the institutions before encrypting all files. Then it uses the copied files to squeeze the victim organization into paying for a decryption key. If not the data will be sold to criminals. Usually the gang gets into organizations by getting passwords for remote access systems or by getting people to fall for phishing emails with infected attachments. The FBI reminds all organizations of the importance of patching, using multifactor authentication to protect logins to computer networks and disabling unused remote access ports. The pandemic has forced a large number of people who use computers to work from home. A new survey of IT security decision-makers for Randori suggests firms that were unprepared had a lot of headaches. Forty-two per cent of respondents said their organizations were compromised because of unapproved or unsecured computers and smartphones connected to the network. Three-quarters said cyber attacks have increased in the past year. Just over half agreed protecting their organization from online attacks has become more difficult. One of the big problems is people who work from home don’t have the IT protection that enterprise-grade security systems provide from their offices. Seventy-six per cent of respondents said prioritizing which applications to patch has...
Install NVM on Linux: Maintain multiple NodeJS versions with Node Version Manager – LinuxTechLab
We have earlier discussed In this tutorial, we will learn about NVM & process to install NVM on Linux. NVM stands for Node version manager & as you might have guessed with name, it’s used to control Nodejs versions installed on our system. It is a command line utility, which allows us to use & switch between multiple versions of Nodejs. It works on Linux & MacOS but does not yet support Windows machines, but there are some other 3rd party tools for Windows to do the same job. Install NVM on Linux The process to install NVM on Linux is simple & same whether you are using Ubuntu or CentOS/RHEL. Firstly we need to download the install script for NVM & run it. Download & execute the install script by running the following command from terminal, $ curl -o https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash Once the script has been executed without any errors, we need to source our .bash_profile for immediately affect the changes made, $ source ~/.bash_profile Now we are ready to use NVM for installing the various versions of Node.JS on our systems. To check & list all the available Node.JS versions, run the following command from the terminal, $ nvm list-remote This would produce the list of all available versions of Node.JS & output will look something like this, We can then choose a version & install it using NVM. Let’s suppose we need to install versions, v0.12.11 & v8.1.3, install them using the following command, $ nvm install v0.12.11 $ nvm install v8.1.3 After installation, we can also set a default version which will start by...
Want to become a web developer? 10 questions you should ask yourself.
So you want to become a web developer? Well then it’s time to put down that “Learn Super Duper Language v8.3 in 24 hours” book. Instead, make it a habit to ask yourself these 10 questions every day. Is there a pattern here? Looking for patterns in what works and what doesn’t work leads to discovering the underlying principles that drive seemingly unrelated concepts and behaviours. To get a deeper understanding of the work that you do make it a habit of asking yourself “Is there a pattern here?”. This applies to more than just your code. Is there a pattern in the types of changes requested by business? Is there a pattern in the way technologies evolve? Are you seeing the same types of bugs popping up again and again? To understand is to perceive patterns – Isaiah Berlin How can I make this simpler? Often as web developers we want to produce complex and scalable solutions. Making something tremendously complex makes you feel like the master of your universe. The problem is that you will never be able to predict how your product and business is going to change in the future. “Architecture” and coding is much more like gardening than architecture. You need to be able to adapt to an ever changing environment. The more complex your solution the more difficult this becomes. Simplicity is the ultimate sophistication. – Leonardo da Vinci Why does it work like that? Knowing that something works and knowing why it works that way are two very different things. If you know why something behaves the way it does you are able...
Making a tiny .NET Core 3.0 entirely self-contained single executable
I’ve always been fascinated by making apps as small as possible, especially in the .NET space. No need to ship any files – or methods – that you don’t need, right? I’ve blogged about optimizations you can make in your Dockerfiles to make your .NET containerized apps small, as well as using the ILLInk.Tasks linker from Mono to “tree trim” your apps to be as small as they can be. Work is on going, but with .NET Core 3.0 preview 6, ILLink.Tasks is no longer supported and instead the Tree Trimming feature is built into .NET Core directly. Here is a .NET Core 3.0 Hello World app. Now I’ll open the csproj and add PublishTrimmed = true. <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>netcoreapp3.0</TargetFramework> <PublishTrimmed>true</PublishTrimmed> </PropertyGroup></Project> And I will compile and publish it for Win-x64, my chosen target. dotnet publish -r win-x64 -c release Now it’s just 64 files and 28 megs! If your app uses reflection you can let the Tree Trimmer know by telling the project system about your Assembly, or even specific Types or Methods you don’t want trimmed away. <ItemGroup> <TrimmerRootAssembly Include="System.IO.FileSystem" /></ItemGroup> The intent in the future is to have .NET be able to create a single small executable that includes everything you need. In my case I’d get “supersmallapp.exe” with no dependencies. Until then, there’s a cool global utility called Warp. This utility, combined with the .NET Core 3.0 SDK’s now-built-in Tree Trimmer creates a 13 meg single executable that includes everything it needs to run. C:\Users\scott\Desktop\SuperSmallApp>dotnet warpRunning Publish...Running Pack...Saved binary to "SuperSmallApp.exe" And the result is just a 13 meg single EXE ready to...How DevOps Plays a Beneficial Role in Mobile App Development
For the last few years, millions of people worldwide have been using mobile devices as the main source of accessing the internet. For this reason, many industries developed a mobile app for their businesses. During the last few years, the IT industry mainly concentrated on fulfilling the market demand and their businesses were focused on making a market existence. However, they ignored to concentrate on app security, code quality, maintainability, and development costs. Now, this is high time to concentrate on such problems and accept new techniques to enhance quality and reduce risks. In this post, I have come up with the approach of DevOps in mobile app development, its benefits, challenges it faces, and how you can implement it in your app development project. So, let’s get started! What is DevOps? DevOps is an exclusive methodology that highlights effective cooperation among all stakeholders engaged in producing a digital product. It incorporates operation staff members, app developers, and project managers. Although the conventional strategies and approach to software development caused extra development costs, time, and client dissatisfaction, DevOps reduces the gap between operations and development and wins over the challenges related to constant software development. The concept behind DevOps for mobile app development is to support a culture of cooperation between teams that earlier worked individually. DevOps is not solely an approach; it can be mainly considered a state of mind or culture. It causes a shift in the mindset, promotes deeper integration, and enhances cooperation. DevOps brings automation, constant delivery, and agile together so that operation and development teams can be more productive and launch software more dependably...
China Strengthens Influence on the U.N. Through Big Data Collection
China’s influence is undoubtedly growing in the United Nations, with four of the 15 specialized agencies of the intergovernmental organization being led by Chinese nationals. Beijing seized the “absence” of the United States, accelerated by the Trump administration’s disdain for the U.N., to extend its tentacles to unexpected places. A plan to set up the first U.N. big data research institute is underway in Hangzhou, Zhejiang Province, China. Officially, it would facilitate U.N. operations by amassing and analyzing huge amounts of data from around the world on sustainable development goals (SDGs) to tackle global issues such as starvation and climate change. One cause for concern is that Chinese researchers are expressing the need for data in order to analyze human behavior. The United States, which is wary of any data leaks to China, is raising alarms against the plan. In an October 7, 2020, article in , Hudson Institute fellow Claudia Rosett warned that the plan would enable China to collect data from U.N. member states and set the standards for data collection. “[T]he U.N. badge of legitimacy would make it easier for Beijing to secure flows of data from member states, influence U.N. standards and norms for such data collection, shape the results, feed them into the U.N. system — and project the Chinese Communist Party’s techno-tyranny around the world,” Rosett wrote. The seat of the Undersecretary-General for the United Nations Economic and Social Council (ECOSOC), which promotes the SDGs, has been occupied solely by Chinese nationals since 2007. Incumbent Liu Zhenmin is a former diplomat who has also served as Vice Minister for Foreign Affairs. Secretary-General of...

Realtime server monitoring app with Angular 4 , NodeJS & Chart.js | Dunebook.com
In this article we will be building a very simple monitor that allows to observe some OS parameters, such as free memory available. In this article we will be using the NodeJS, Angular 4 and Chart.js, so ensure you have node and Angular studio IDE installed. To create our development server we will be using vagrant, so check here for instructions to install vagrant on your operating system. We will be creating two code repos, the first is a node application that will monitor the OS parameters and sends it via websocket to the second app which is an Angular 4 application, the Angular app will utilize Chart.js to represent the server status graphically. Server App Let’s create our server app, by running the following commands in our terminal We want our server to run Ubuntu 16.04, have a static IP address 192.168.50.4 and have NodeJS installed, so replace the content of Vagrantfile with and create a provisioning script named bootstrap.sh with the content In the script above, we first update the apt repository and then we install NodeJS from a private PPA, install build-essential which is required by some NodeJS modules and install forever which helps us keep a node script running forever. No we start the vagrant server with th command: Lets create a package.json file with the content below in our duneserver directory Our package.json contains 3 dependencies, os-monitor–a very simple monitor for the built-in os module in Node.js, nodemon–monitor for any changes in your node.js application and automatically restart the server – perfect for development, and socket.io–enables real-time bidirectional event-based communication. Let us create our...
Introduction to Ruby on Rails Patterns and Anti-patterns | AppSignal Blog
Welcome to the first post in our series about Ruby on Rails Patterns and Anti-patterns. In each of the posts, we’ll take a deep dive into all sorts of patterns you might come across while working with Rails apps. Today, we’ll show what a (design) pattern is and then try to explain what an anti-pattern is as well. To better illustrate explanations, we will use the Ruby on Rails framework that has been around for quite some time. If Rails isn’t your cup of tea for some reason, hang on, the ideas (or patterns) described here might resonate with whatever technology you wind up using. But before we jump into explaining what patterns and anti-patterns are, how did we get to the point where we need them? Why do we need to have all these things for our software? Why do we need to design our solution? Yes, You Are a Designer Even from early computer programming days, people had to deal with the design of the programs they were writing. To write a program (or software) is to design a solution for a problem. When you write software, you are a designer—feel free to append that to your job title. Designing good solutions is important because the software we write will be read and/or edited by others. Also, the solutions we come up with will be built on by others in the future. Having all this in mind, generations of engineers started seeing similar designs in code and architecture throughout their careers. Folks started extracting and documenting standard solutions to problems. Some would say it’s a natural way...
How to understand a component’s lifecycle methods in ReactJS
In this article, we are going to explore the lifecycle methods of ReactJS. But, before moving ahead to React’s different lifecycle methods, we should understand what it is.As we know, everything in this world follows a cycle (say humans or trees). We are born, grow, and then die. Almost everything follows this cycle in its life, and React components do as well. Components are created (mounted on the DOM), grow by updating, and then die (unmount on DOM). This is referred to as a component lifecycle. There are different lifecycle methods that React provides at different phases of a component’s life. React automatically calls the responsible method according to the phase in which the component is. These methods give us better control over our component and we can manipulate them using these methods.At present, we know what lifecycle methods are and why they are important. So what are these different methods? Let’s have a look into them. Lifecycle Methods A component’s lifecycle is broadly classified into four parts: initialization mounting updating, and unmounting. Let’s discuss the different lifecycle methods that are available at these different phases (i.e., initialization, mounting, updating & unmounting). Initialization This is the phase in which the component is going to start its journey by setting up the state (see below) and the props. This is usually done inside the constructor method (see below to understand the initialization phase better). class Initialize extends React.Component { constructor(props) { // Calling the constructor of // Parent Class React.Component super(props); // initialization process this.state = { date : new Date(), clickedStatus: false }; } Mounting The name is self-explanatory....How the IoT is Shaping the Future of Mobile App Development?
With rapid speed, the mobile app development industry is encountering innovative and crucial changes because of the rise of different modern technologies. And IoT (Internet of Things) is one of such technologies. IoT has arrived in recent years. And now, people from sectors like healthcare, retail, agriculture, and more are enjoying IoT solutions. IoT can aid communication and interaction at every level. The rising demand for such apps and ease of utilization are two basic factors why IoT app development services are growing. According to the statistics, in 2030, It is predicted that there will be approx 25.44 billion IoT connected devices. Here, in this blog, let’s discuss how IoT is the future of mobile app development. However, to understand that properly, let’s first know this technology in brief! What is IoT (Internet of Things)? IoT technology is the network of physical things that are developing at a rapid rate. Due to IoT, an IP address, the fundamental of every mobile application, has become stronger. Undoubtedly, this technology has brought the connectivity we always dreamt of. In simple words, the IoT is one of the modern technologies that help us with nearly every aspect of life. Hence, everything that has internet access can be connected by IoT. For this reason, this technology helps us control our daily-use devices, even if we are not present at home. IoT has made a meaningful effect on the app development industry, as the data sharing between gadgets makes sure a smooth user experience. Improved visibility obtained from the data sharing has been a result that has considerably improved the mobile apps’ quality in...
