As an entrepreneur who is looking for a digital partner for the development of their very own application, it can be difficult to follow the technical jargon that’s mentioned in many consultancy meetings and proposals. If you’re not a software developer yourself, the information regarding technical specifications can be complex and difficult to understand. As a company of digital experts, we want to make sure our clients are always on the same page as us, no matter how complex the topic. That’s why we have been taking a deep dive into the technologies and frameworks our development team at Lizard Global works with on a daily basis. This week, we’re having a look at our MERN tech stack, and the programming language NodeJS in particular. The tech stack of MERN MERN is a full-stack web development framework made up of four important Javascript technologies: MongoDB, ExpressJS, ReactJS, and NodeJS. All layers of application development are covered by these four technologies. At Lizard Global, we use ReactJS for the UI (frontend), ExpressJS and NodeJS for the server and MongoDB for databases. Since these technologies are carefully picked to work together seamlessly, the MERN tech stack allows us to build high-quality applications in an efficient and agile manner, while accommodating fast-changing requirements. Reading an object from database and sending it to the browser (Node & MongoDB) Introducing NodeJS NodeJS is a programming language, a modified version of Javascript that can be run outside the user’s browser, typically on the server. It’s extended with some modules to be able to interact with the server such as reading the file system or sending...
One big misconception, a full stack web developer is an empty title or someone like ‘jack of all trades, master of none’. So not true! What skills a full stack developer must have or acquire? What are the core responsibilities? What programming languages full stack developers must know? Do you know the average salary of full-stack developer in US? The average salary base is $105,556 / year – Indeed A confusion raises as if they will be doing the development or management or responsible for handling the end product/service? Well, almost all of this and more. In this blog post, we will try to cover what is a full stack developer and what skills/role he has to perform in product/ project development in detail. What is a full stack web development? Someone who works on the backend (server-side), and the frontend (client-side). In short, someone who can play in a variety of coding niches either related to databases, web design or user experience, can guide in the best way possible. While looking into the responsibilities of the full stack web developer, he is the one who helps in the design and development of software. Test and debug software for optimization purposes, write clean standard code both for front and back end applications. He can design interactions on the web apps, build databases and servers for backend software running. Looks into cross-platform compatibility of applications, maintains the responsiveness of given design, research and can add new features in a product, develop APIs and RESTful services, reduce security risks and help in scalability. Why is the role of full stack developer...
This article is about decoding some of the popular jargon used in data science. It is important to understand these concepts better. They are commonly asked in data science job interviews. Let’s get into the topics. Dependent and Independent Variables A dependent variable (target variable) is driven by the independent variables in the study. For example, the revenue for a retail store depends on the number of customers walking into the store. Here the store revenue is the dependent variable. The number of customers walking into the store is the independent variable. The dependent variable is called so because its value depends on the independent variable. Also, independent variables are called so because they are independent of other variables that could impact the dependent variable. Like, the amount of rainfall (independent variable) is independent of the number of customers walking into the store. Both these independent variables help in making a better prediction. While working on a predictive data science problem. There would be generally one dependent variable and multiple independent variables. Below is a very good resource to better understand dependent and independent variables. An outlier is a value that is not within the normal range for a variable. For example, the average life expectancy is around 70 years. An individual who is of age 119 is considered an outlier because his age is well outside the normal range. While working on a data science problem, it is a general practice to check for outliers in the dataset. Outliers in data could impact the choice of the algorithm in case of a predictive problem. Here is a detailed...
This blog series is all about a step-by-step guide to the mobile app ideation and discovery phase. It explains the significance of planning your mobile app development journey right from clarifying the vision to coming up with a solution. Also, this post describes how the right product discovery strategy proves beneficial in the longer run. You’ll learn the basics of conducting product ideation, who should be involved in this step, and some of the best practices to implement that simplifies your mobile app development process. So, let’s understand what product discovery in mobile application development exactly means. What is Product Discovery in Mobile App Development? When it comes to custom , product discovery stands imperative to target the right audience and how your app solves a genuine problem prevailing in the market. It is a continuous process of brainstorming ideas or solutions and subsequently adopting them to offer customized user experiences. With a good mobile app discovery phase, you can direct your development team to understand the needs of the user base in advance before moving on to the development. Here’re some questions you need to ask to correctly define it: Are there any other options available in the market to solve the issue your app aims to target? What are the distinctive factors that give it a competitive edge? What are the core competencies in terms of features and usage of your mobile application? What value do they bring to the table? What is the scope of your app? How will it reach out to your potential users? Is your app capable of satisfying your user base consistently?...
Myanmar’s military junta is reportedly on the brink of passing its long-threatened cybersecurity law, which in its latest form would outlaw virtual private networks (VPNs), throttle access to social media networks, and force internet companies to hand over user data to the military. The latest version of the Cyber Security Bill, which updates a draft released in February 2021, comes a year after the military seized power, plunging the country into a zero-sum struggle between the junta and a loose coalition of opponents. According to a report last week by Myanmar Now, the military administration submitted a revised version of the bill to stakeholders on January 13 and called for their feedback by January 28. The law is expected to be passed this week. The February 2o21 draft was widely criticized for compelling internet providers to prevent or remove any content deemed to “cause hatred, destroy unity and tranquility,” any “untruthful news or rumors,” or anything that is “inappropriate” to Myanmar’s culture. It also forced internet providers to gather the personal data of users, store it for three years starting from the day of usage, and hand it over to military authorities upon request. While the draft was withdrawn due to the strong opposition of Myanmar’s business community, the advocacy group Free Expression Myanmar (FEM) (which has also released an unofficial translation of the legislation) claims that the military’s new draft “repeats the repressive provisions of previous drafts and adds more, seriously threatening the safety and security of Myanmar’s digital space.” Diplomat Brief Weekly Newsletter Get briefed on the story of the week, and developing stories to watch across...
