Doing a frontend technical interview with ReactJS – DEV
There are many ways to conduct a technical interview, and they depend from company to company. You might get whiteboard designing of architecture system, writing an algorithm, or some coding challenge. After working with multiple companies and going through many interviews from both sides, I prefer coding ones. More specifically, making something like a to-do application. By doing it, in an hour, I can assess if a person is junior, mid-level, senior, or architect. In this text, I cover how I do it and what knowledge I expect for which experience level. Application to build I prefer a to-do application. The model for an item of it is straightforward. All you need is a text, a unique identifier, and some flag indicating its status. All to-do applications display the list of all items, enable input of a new item, toggle the item’s status, and delete them. I don’t expect to spend more than 45 minutes up to an hour. That is not a long time, so I don’t expect candidates to do everything, just enough to show how they think and what they know. I provide candidates with initial data. It is just a JSON file with few items located in the public folder. In React, every file located in that folder is available, and this one you can request by making a get request to /todo.json. I am okay with googling for documentation, and I make it clear at the beginning of the interview. And this is also an indicator of candidate experience level. If the candidate checks documentation for some API, that is fine. But if the candidate...A Beginner’s Roadmap to Becoming a Full-Stack Web Developer
Becoming a full-stack web developer requires you to hide tons of skills. For beginners, it’s often tough to seek out the proper learning path and to realize the quick results. At first sight, it’d be overwhelming to know what you would like to find out and the way everything fits together at the top. This post will offer you a summary of technologies you’ll concede to learn for being a full-stack developer in 2019 and beyond. We’ll start to require a glance at the inspiration and programming languages then move forward to more advanced topics like frameworks and extra tools.

Foundation The best thanks to beginning your web development career is to urge excellent at HTML & CSS which is that the basis for everything else. HTML & CSS The Hypertext terminology (HTML) is important for each website you’re implementing. By using HTL you’re defining and structuring the content of an internet site by employing a simple markup syntax. Cascading Style Sheets (CSS) may be a simple way for adding styling to your websites (e.g. adding fonts, colors, layout etc). Having understood HTML you ought to definitely advance to CSS and confirm to know the fundamentals. HTML and CSS are two essentials every web developer must know. This was valid in 2018 and can even be valid in 2019 … Programming Languages Learning JavaScript...Top 18 Most Common AngularJS Mistakes That Developers Make | Toptal
Single page apps demand the front-end developers to become better software engineers. CSS and HTML are not the biggest concern anymore, in fact, there is no longer just a single concern. The front-end developer needs to handle XHRs, application logic (models, views, controllers), performance, animations, styles, structure, SEO, and integration with external services. The result which emerges from all those combined is the User Experience (UX) which should always be prioritized. AngularJS is a very powerful framework. It is the third most starred repository on GitHub. It is not difficult to start using, but the goals that it is intended to accomplish demand comprehension. No longer can AngularJS developers ignore memory consumption, because it will not reset on navigation anymore. This is the vanguard of web development. Let’s embrace it! Common Mistake #1: Accessing The Scope Through The DOM There are a few optimization tweaks recommended for production. One of them is disabling debug info. DebugInfoEnabled is a setting which defaults to true, and allows for scope access through DOM nodes. If you want to try that through the JavaScript console, select a DOM element and access its scope with: It can be useful even when not using jQuery with its CSS, but should not be used outside of the console. The reason being that when $compileProvider.debugInfoEnabled is set to false, calling .scope() on a DOM node will return undefined. That is one of the few recommended options for production. Please note that you can still access the scope through the console, even when on production. Call angular.reloadWithDebugInfo() from the console and the app will do just that. Common...Different Types of Mobile App Development | Webiotic
When getting started on developing a mobile app, it’s easy to get carried away thinking about how your app will look and function, , and the overall value you imagine it bringing to your users. But one of the first things you should be thinking about is what type of app you’ll build. There are native apps, hybrid apps, web apps, and progressive web apps. Choosing the right type is crucial to bringing your dream app to life, so think carefully about the decision. In this article, we’ll bring you up to speed on the different types of , the technology behind them, and how to make the right choice. Chapter #1: Native Mobile Apps When you hear the term “native app”, this simply means that the mobile application was built for a specific operating system (OS). Most mobile devices use either iOS or Android OS. So creating an app that’s native to one of these systems means making the most of the device’s functionalities. With that said, , for example, can’t be used for other platforms, like Android devices. 1.1 How Native Apps Work First and foremost, native apps are coded using like Kotlin, Java, Swift, and C++. They function by having complete access to a device’s hardware and functionality. The platform provides developers with a set of standardized tools, libraries, code samples, and documentation, also known as a software development kit (SDK), that will help them create an app for that specific platform. Platforms also provide an integrated development environment (IDE) for developers to use to write and test their software. This is a software suite that...How to upskill your team to tackle AI and machine learning | VentureBeat

What Is Ruby on Rails?
Ruby on Rails (or “Rails”) is an open-source web application development framework written in the Ruby programming language. It’s one of the most popular Ruby libraries and one of the top reasons developers choose to learn Ruby. Modern web applications can be very complex with many layers. Rails makes web development easier, providing a pre-built structure for development and everything you need to build a web app. In this article, we’ll look at what Rails is used for, its advantages and disadvantages, and what jobs you can get if you know this framework. Then, we’ll show you how to get started using it to build your own web apps. What is Ruby on Rails used for? We explained that Ruby on Rails is a web framework, but it helps to know what a web framework is to know just how powerful a tool like Rails can be. A framework simplifies the creation of web applications. It does this by providing default structures for your code, any databases you use, and the web pages the application will serve. You can think of a framework almost like Legos. With a framework, you get pre-built “Legos” of code that you can mix, match, and modify to build a custom web application, which means you don’t have to create everything from scratch. Ruby on Rails uses the Model-View-Controller (MVC) architectural pattern used by many other web frameworks — one of the most well-known patterns in development. The MVC pattern separates a web application’s code into three interconnected parts: This pattern makes Rails very flexible and useful for all types of web applications. Rails...Building a GraphQL API with ASP.NET Core 2 and Entity Framework Core
Building a GraphQL API with ASP.NET Core 2 and Entity Framework Core Published Mar 29, 2018 • Updated Mar 26, 2020 GraphQL is a relatively new technology developed initially at Facebook and open-sourced to the world in 2015. In 2017, it really took off and made the leap from a cool, niche technology to one of the primary ways companies like Walmart and IBM are starting to work with their APIs and data. If you’re new to GraphQL, here’s a definition that sums it up nicely. GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data. GraphQL isn’t tied to any specific database or storage engine and is instead backed by your existing code and data. The last sentence is an important one to be mindful of when getting started with GraphQL. So, I’ll repeat it by saying GraphQL is not any specific framework or database but rather a that describes the capabilities and requirements of data models in client‐server applications. There’s a growing number of libraries out there to help you implement the GraphQL spec in your app for a number of different languages. In this post, we’ll learn about designing and building a GraphQL powered API using ASP.NET Core 2, Entity Framework Core and Joe Mcbrides’s excellent graphql-dotnet library. Benefits of GraphQL Before we dig into the code, it’s worth pointing a few fundamental issues with REST that GraphQL solves and why we may want to choose it over a traditional REST approach in certain scenarios. 1. GraphQL Is Less Chatty than...

Stumbling into Cyber Security: How One Research Topic Changed my Trajectory | Honors College Blog
My name is Catherine Caldwell, and I am a senior double majoring in French and International and Global Studies with a concentration in peace, security, and human rights in the J. William Fulbright College of Arts and Sciences. Though I have been working on this topic for quite some time, I officially began writing my honor’s senior thesis in fall 2020 with Dr. Laurence Hare, the Director of International Studies, as my mentor. I will defend my thesis and graduate in the spring of 2021 with the intention of attending law school in the fall. My research into the field of cyber security has been in progress since the summer of 2019. I first became interested in the subject during my time at School for International Training in Geneva, Switzerland, when I sat in on a lecture on cyber terrorism and decided to use it as the topic of my capstone project. However, I quickly realized that there was much more to cyber security than I initially realized and decided to establish a foundation of information with the intent to do further research upon my return to the University of Arkansas. Thankfully, I was able to continue my research in Dr. Hare’s Technology and Global Affairs seminar by looking into how multinational corporations have managed to navigate the varied landscape of cyber security within different nations. The thesis topic that I have finally settled on utilizes the knowledge I have gained from these previous two projects and seeks to understand whether positive peace theory is applicable in modern frontier spaces, like cyberspace. Positive Peace is considered to be peace...
