In this article, you will learn how to use Spring Boot and HarperDB to create a microservice. Later on, you will also look at how to deploy the complete application on AWS Elastic Beanstalk.
You will be building an Employee Leave Management System. This application will be responsible for tracking the detailed record of employees' leaves. You will also be implementing the functionality to add, edit, and cancel leaves.
I think you'll agree with me when I say that the words "database" and "intrusion" are not words you want to hear in the same sentence. Databases house critical information that needs to be kept private for our businesses and our customers - we can't have criminals exploiting gaps in our security and accessing this information.
Fortunately, we can take steps to stop intruders from getting in and catching them if they manage to sneak in anyway. Let's learn about these methods and how we can put them to good use to protect our valuable data. We'll explore two systems - the IPS and the IDS - and take a look at how they compare and what you should think about when implementing them.
Code refactoring provides a well-needed mental break for developers, and I think many devs can relate to this. Writing code all day is very demanding, especially if you create new functionality day by day. It’s a taxing exercise, and developers often need some space to think about the codebase's overall organization and look back on what can be improved.
This is exactly what code refactoring does. It provides this well-needed mental break for developers, and it gives them the chance to tackle higher-level, codebase-related issues. However, it’s also a great moment to check your code against the codebase guidelines. No codebase is perfect. Small faults against the guidelines make it to the “main” branch.
Hello folks, if you want to become a Python web developer and wondering which Python frameworks, libraries, and packages you can learn then you have come to the right place.
Earlier, I have shared the best Python courses, Python interview questions, and python libraries to become a better and competent python developer, and today, I am going to share the best Python framework you can learn to become a full-stack Python developer.
If you're a developer keen on Blockchain development, you must be aware of NFTs (also known as Non-Fungible Tokens). In this post, you'll talk about the technology behind them to help you begin building your own.
When you finish the course, you'll be able to access your personal Ethereum wallet, with a brand new NFT within it. This tutorial is easy for beginners and doesn't require prior understanding regarding ethereum or smart contracts. Ethereum system or even smart contracts.
Much like running up bills on your credit card, technical debt can easily get out of hand. To avoid this happening, you need to keep track of how much debt you’re building up.
Technical debt metrics are designed to help you make sense of all the data you collect. There are many different metrics to choose from nowadays, and plenty of tools for recording the data.
React is a component-based open-source JavaScript library for building user interfaces. It is used for handling the view layer in web and mobile applications, and it is great for building single-page web applications.
Some of the features of React are:
I'm the founder of Tellspin, an on-call scheduler in Slack for DevOps and developers (https://tellspin.app). Helping workspaces reduce their contact footprint, resolve incidents faster, and regain deep focus.
Code smell is a way to describe code that hasn’t aged well and has the potential for a lot of issues.
Today, we discuss C# code quality and a variety of errors by the example of CMS DotNetNuke. We're going to dig into its source code. You're going to need a cup of coffee...
DotNetNuke is an open-source content management system (CMS) written mainly in C#. The source code is available on GitHub. The project is part of the .NET Foundation.
Maybe you're a newbie dev, in a coding academy, or newly graduated. Or perhaps you're old and cynical like me. The reality is, tech moves fast, and it's easy to get distracted by the latest software, tool, or trend.
But while you're floating in YouTube videos, Reddit boards, and StackOverflow, we've got something to keep you anchored: the good coding practices in software engineering. I've deliberately approached this article with broad strokes to move a little beyond the typical laundry list. Let's take a look at the software engineering best practices that high-performing teams follow.
While many guides to creating forms for the web are mainly focused on the frontend, security goes beyond that. We have to consider the current user, other users, and our own security. As such, we will look at the whole application architecture from frontend to backend and beyond.
Before we get too far, I will be using the term “SSL” to refer to a technology used to encrypt traffic on the internet. Technically, I mean Transport Layer Security (TLS), but “SSL” is commonly used and understood to mean the same thing. It’s what gives websites the little green lock in the URL bar and why they start with “https” instead of “http” (no “s”).
Let’s start with a brief definition.
The Dunning-Kruger effect is the phenomenon whereby people with little knowledge tend to overestimate their abilities, precisely because they ignore how much knowledge is necessary to master them.
The purpose of the following websites is to help you test to what extent your programming prowess is able to solve problems low to high. Not only that, but there you also have to compete with other developers to achieve higher rankings. Just like playing games, we have to go from low rankings like copper, silver to gold, platinum. Here are some websites to help increase your interest in programming.
The Exercism website is home to thousands of exercises that you can practice in over 50 supported programming languages. Its exercises are also varied for beginners or those with a lot of programming experience. It is open-source and based on donations from developers around the world so you can rest assured that it won't be charged. In addition, if you feel you are capable, you can also contribute helpful exercises to the community that will improve your programming skills and others.
The filter() the method creates a new array filled with all the elements of the old array that pass a certain test, provided as a function.
Let’s take a look at the syntax:-
JavaScript methods are actions that can be performed on objects. So here is my new blog post I will cover the two JavaScript methods map() and filter(). Will explain easily and in detail.
The map() method is used to apply a function on every element in an array and then return a new array. Let's take a look at the syntax:
Forms are arguably the most important parts of any web application. Without forms, we would not have sites like Google, Facebook, Amazon, Reddit, etc. However, the more I browse the web, the more I see poor implementations of forms.
In this series, we will examine the proper steps to creating forms for the web, how to think about the code we write, and considerations to make along the way. The series is broken up into the following parts:
You are probably aware that there are seemingly endless options to consider when it comes to selecting a database and other technologies for your mobile app. With so many choices, it can be difficult and confusing to determine what really matters when it comes to your tech stack. A little while back, I wrote an extensive article on the different database architectures and use cases available to provide guidance on picking the right technology for the right project. While that is still an accurate and solid resource, this article takes a deeper dive into considerations for improving the performance of, specifically, mobile apps.
First and foremost, perhaps we should take a quick look at the difference between mobile and web apps. Mobile apps live and run on a mobile device itself, whereas web apps are accessed through a web browser and will adapt to whichever device you're viewing them on. Native mobile apps are built for a specific platform, such as iOS for Apple or Android for, well, pretty much everything else. They are downloaded and installed through an app store and have access to system resources, such as GPS and the camera function. Web apps, however, are not native to a particular system and do not need to be downloaded or installed. Due to their responsive nature, they may look and function a lot like mobile apps, which is where some confusion arises.
Today, we’re releasing a full-length Introduction to Computer Science for Beginners course on our YouTube channel. The course, taught by Treehouse’s Richard Tillies, is a 21 minute workshop that unpacks the history of computer science, defines key terms, and identifies...
