This article was originally published at strilliant.com — please give some love to the original! ❤Separating your frontend and backend has many advantages: The biggest reason why reusable APIs are popular — APIs allow you to consume data from a web client, mobile app, desktop app — any client really. Separation of concerns. Long gone are the days where you have one monolithic-like app where everything is bundled together. Imagine you have an extremely convoluted application. Your only option is to hire extremely experienced/senior developers due to the natural complexity. I’m all for hiring juniors and training your staff, and that’s exactly why you should separate concerns. With separation of concerns, you can reduce the complexity of your application by splitting responsibilities into “micro-services” where each team is specialized in their micro-service. As mentioned above, the on-boarding/ramp-up process is much quicker thanks to splitting up responsibilities (backend team, frontend team, dev ops team, and so on) Forward thinking and getting started We will be building a very powerful, yet flexible, GraphQL API based on Nodejs with Swagger documentation powered by MongoDB.The main backbone of our API will be Hapi.js. We will go over all the technology in substantial detail.At the very end, we will have a very powerful GraphQL API with great documentation.The cherry on top will be our integration with the client (React, Vue, Angular) Prerequisites NodeJS installed Basic JavaScript — if you feel wary, check out this article for the best courses to brush up on your JavaScript game Terminal (any will do, preferably bash-based) Text editor (any will do) MongoDB (install instructions here) — Mac: brew...
China has used big data to trace and control the outbreak of COVID-19. This has involved a significant endeavour to build new technologies and expand its already extensive surveillance infrastructure across the country. In our recent study, we show how the State Council, the highest administrative government unit in China, plans to retain some of those new capabilities and incorporate them into the broader scheme of mass surveillance at a national level. This is likely to lead to tighter citizen monitoring in the long term. This phenomenon of adopting a system of surveillance for one purpose and using it past the originally intended aims is known as “function creep”. In China, this involves the use of big data initially collected to monitor people’s COVID status and movements around the country to keep the pandemic under control. The Chinese government has been quite successful at this, despite recent spikes in infections in eastern China. But this big data exercise has also served as an opportunity for authorities to patch gaps in the country’s overall surveillance infrastructure and make it more cohesive, using the COVID crisis as cover to avoid citizen backlash. AP: Chinatopix How does China’s COVID surveillance system work? Two key shifts have occurred to enable more comprehensive surveillance during the pandemic. First, a more robust system was constructed to collect and monitor big data related to pandemic control. Second, these data were then collated at the provincial levels and transferred to a national, unified platform where they were analysed. This analysis focused on calculated levels of risk for every individual related to possible exposure to COVID. This is...
Defining Mobile App Development Framework In simple terms, a mobile app development framework a collection of tools that help developers to create mobile applications. The framework offers a sturdy structure that boosts the process and gives support to mobile app development. The advantage of the mobile app development framework is that it is cost-effective.

EXECUTIVE SUMMARY: The world runs on technology. Regardless of your industry, software powers your enterprise. Roughly 10% of enterprises use more thoftware apps. Much of the time, these tools require usernames and passwords for each user. Does this translate to too many accounts to keep track of? Unused accounts can pose security risks, both for organizations and for individuals. Why we have too many accounts Remember that time when so-and-so encouraged your enterprise to check out a free trial version of that new software service? Or that one-off occasion when you ordered a bottle of whisky as a thank you gift for a business partner? The online accounts created and no longer used could leak company or personal credit card information, passwords or other sensitive data. Unused online accounts, aka “zombie accounts,” can pose significant security risk. If a data breach hits the host organization, your enterprise could suffer downstream effects, which could manifest in a wide variety of different ways. It’s more common than you might think. Examples of “zombie account” risks For enterprises, certain types of older, unused administrative accounts can place your online environment in jeopardy. While administrative accounts used to represent a necessary component of platform use, today’s technology configurations mean that many of these accounts can be closed. Removing administrative account access when unnecessary can help limit security vulnerabilities. For enterprises and employees alike, “you may be supplying a steady stream of personal data to online companies you’ve forgotten about,” warns a consumer report. These companies may collect calendar information, contact information, or even bank account details. Because unused accounts are usually out-of-sight and...
Setting up a project with Ruby on Rails, PostgreSQL and GraphQL is actually pretty straightforward. But first, some prerequisites. For this tutorial (tested on versions 2.7.3, 6.1.4.1 and 11.0 respectively), you must have all three, Ruby on Rails, PostgreSQL and GraphQL installed on your development machine. Some general knowledge of Ruby and Rails is also recommended. Before we begin, however, you might be wondering why anyone would want to replace the perfectly fine experience provided by the traditional REST API with one offered by GraphQL. Well, one obvious reason is that GraphQL deals quite elegantly with resources over- and under-fetching. With GraphQL you are given the exact information you request – nothing more, nothing less. Moreover, it is almost self-documenting, making that one less item on your list of things to worry about. And there are other pros to GraphQL, such as it being both strongly typed and language and database independent. But in the meantime, I’ll leave those for you to explore on your own. So, without further ado, let’s set up our first GraphQL API on Ruby on Rails. Setting Up GraphQL for Rails Step 1 – PostgreSQL database Let’s create a Ruby on Rails API app with PostgreSQL as the database. We’ll be making a very simple bookshelf API. Step 2 – GraphQL to Gemfile Let’s add GraphQL to our project. To do so, add gem ‘graphql’ to your Gemfile. For testing your queries in development, add gem ‘graphiql-rails’ under the development category. Now, let’s install our gems. Make sure that your config/routes.rb includes the following: Step 3 – Create database Time to create the database...
