React Native is an excellent entering point to app development for a web developer, especially with React experiences. However, it does not mean that React Native is simple. You can write apps with your familiar language, JavaScript, but it certainly requires an overall understanding of iOS and Android platforms. This article is a summary of my learning process on the React Native architecture and the ecosystem from the web developer point of view. The Execution Environments React runs on the JavaScript runtime environment. For the web, it is a web browser. There is a single JavaScript thread, and it uses web APIs implemented natively in the browser. It is important to understand how the callbacks work between the main JS thread and Web APIs, especially when using asynchronous functions. This interaction between JavaScript engine and native APIs are also vital to understand how React Native behaves in its environment. Threads in React Native There are three key threads in React Native execution environment, JavaScript thread, Native main thread and the background thread to handle Shadow Node. In the current architecture, the communication between these threads happens over the library called “bridge”. The React Native team is actively working on the major architecture upgrade and this article gives a great overview of why and how the change is needed. I don’t get into the details, but the basic understanding of the current and future architecture helps to model your application, especially to separate the concerns. React and React Native As you can see above, React Native covers a significantly broader area than React itself. React for the web looks rather...
I’m thrilled to announce the newest member of the Laravel ecosystem: Laravel Nova . Nova is a beautifully designed administration panel for Laravel. We’ve sweat the small details and carefully crafted Nova to not only look great, but to be a joy to work with.In this post, I’ll go over the key features of Nova; however, be sure to watch the recording of my Laracon talk for an in-depth demo of Nova’s features . Preface Nova is installed via Composer as a Laravel package. It doesn’t interfere with your existing application in any way. In fact, you can install Nova into existing Laravel 5.6 applications that you have already built.On the front-end, Nova is powered by Vue.js, Vue Router, and Tailwind.css. This makes for a powerful, flexible combination, especially in regards to customization — it’s a breeze to build custom tools, cards, and fields.Each Eloquent model in your application has a corresponding Nova “resource” class which defines its fields, actions, filters, lenses, and cards. Nova is configured entirely using simple PHP classes. No configuration is stored in the database. Resource Management Of course, a primary feature of Nova is the ability to create, read, update, and delete resources in your database. We have worked hard to cover all of the edge-cases in this regard. Need to update the data on the “intermediate / pivot” table of a polymorphic many-to-many relationship? We have you covered. Nova has wonderful support for all of the various Eloquent relationship types.Resource detail views give you instant access to a resource’s information, as well as its related resources — all with lightning fast search, pagination,...
The radical increase in mobile users has entailed the improvement of the mobile app industry. Mobile application development agencies help businesses in planning and designing exclusive and robust mobile apps that can fulfill the requirements of clients. People are depending more on mobile apps for performing daily jobs. And these applications consume lots of data. To assess and handle this data effectively, you need a unique data management tool. This is where big data analytics plays a role. It helps organizations get data-driven understanding from apps. What is Big Data? These days, tools, devices, and people create a diverse and dynamic volume of data. And this amount of data requires scalable, creative, enhanced, and new technology for analytics, hosting, and collection. The big data technology processes data gathered for deriving rich and real-time business information associated with productivity management, performance, profit, users, augmented shareholder value, and risk. Speed is the main factor in the world of Big Data. Generally, conventional analytics concentrates on the assessment of historical data, while, you can encompass the real-time data, using Big Data Analytics. Some top international brands that have used Big Data for boosting the operations of their organizations are: Netflix Capital One American Express Starbucks Amazon What is The Requirement Of Big Data In Mobile App Development? As per a Statista survey report, the global number of mobile application downloads is predicted to increase to 258.2 billion by 2022 and was 205 billion in 2018. This wide mobile app user base creates large volumes of raw data. Raw or unstructured type of data requires high-level analytics for testing the numbers and creating...
2020’s SolarWinds cyberattack, which affected numerous US government agencies, underscores the growing relevance of IT security and cyber-crime to national governments. Not solely the work of individual criminals, crimes perpetrated by state-sponsored or entirely state-operated hacker groups have increasingly been alleged. With cyberspace growing in importance as a frontier of political contestation, states must act; what steps has Japan been taking, and what barriers are there to enhancing Japan’s cybersecurity? The SolarWinds hack involved a group of hackers, , sneaking malicious code into the update system of the SolarWinds IT management software. Compromised updates were then downloaded by the software’s users, which range from . As a result, the hackers likely gained access to data critical to economic competitiveness and national security. This incident underlines the risk posed by cyberattacks that use non-state vectors to their advantage. Though Japan does not seem to have become a significant victim of the SolarWinds hack, its current state cybersecurity strategy is vulnerable to a similar attack due to weaknesses in areas such as its funding and focus. Japan’s Cyber Security Forces Today At the time of writing, the Japan Self-Defence Force (JSDF) operates a Cyber Defence Group of 290 personnel under the control of the SDF’s Command Control Communication Computers Systems Command (C4SC). Combined with cyber defence personnel already under the umbrella of the C4SC, Japan has approximately dedicated to cyber security for the JSDF as a whole. It is worth noting that each branch of the JSDF (ground, air and maritime) has its own dedicated cyber defence unit; these units combined total around 370 personnel. There also exists a small of...
You may have come across Ruby on Rails, NodeJS, AngularJS, JavaScript, and perhaps the “MEAN” stack — MongoDB, ExpressJS, AngularJS, NodeJS — in your research of the different programming technologies. Newcomers will often gravitate towards learning only JavaScript — a single programming language — but it’s often mistaken as a shortcut to becoming a full-stack web developer. Yet, the “MEAN” stack can provide simpler solutions to a wider variety of problems. I frequently get asked questions like this: If I learn JavaScript and not the “MEAN” stack — MongoDB, ExpressJS, AngularJS, NodeJS — will web development be 4x easier for me? If I focus my time on JavaScript, will I be 4x better than any developer who uses those four technologies? It seems intuitive that we would be 4x better off as a full-stack JavaScript developer, but this is a common misconception. That’s okay, let’s explore why. Domain Specific Knowledge Learning JavaScript alone is not a fast track to full-stack web development. Learning only a programming language’s syntax — domain specific knowledge — doesn’t mean we’ll become a better full-stack web developer. Domain specific knowledge alone will make our skill progression a negligible amount easier in the grand scheme of any developer’s career. There is a better approach. Procedural Knowledge The smart way to becoming a full-stack web developer is by first learning how to figure out the things that we don’t know — procedural knowledge — and how to teach ourselves foreign concepts. If we want to make the long-term decision that will benefit the growth of our developer careers, we need to think of programming languages differently....
