If you want to access data in a distributed environment such as in a microservice architecture, then data services are the way to go. The idea is to create a data abstraction layer (DAL) that the rest of the system’s applications and services can share. Thus, a data service gives you a generalized interface to the data you’re exposing and provides access to it in a standard manner. This would be in a well-understood protocol and a known data format. For example, a popular approach is to use JSON via HTTP/S.

Cybercrime is one of the world’s fastest-growing threats, with malicious actors constantly elaborating their methods of undetectable intrusion.

When you have multiple developers working on the same code, you may face a lot of challenges when merging. That's where branches come in.

If you are looking for some kind of metal panel business idea, allow me to be clear: the Rust I am referring to is a programming language.

Here's a problem. You have an object in your code exposed via an export. You also have a function in the same file (also exported) consuming that object directly.

Isolating features into different branches is a crucial practice for any serious developer. By separating each feature, bugfix or working experiment you will avoid a lot of problems and keep your development branches clean.

Git toolbox provides multiple unique tools for fixing up mistakes during your development. Commands such as git reset, git checkout, and git revert allow you to undo erroneous changes in your repository.

A lot of us have struggled with algorithms and data structures. When I began with programming at my University, the name of a subject that got my attention and got me motivated to find my life call was the Principles of programming. I started devoting a lot of time to figuring out how to solve professors' assignments. Now those algorithms are easy for me but then they were not, and I couldn’t pass the exam, I had the wrong approach in learning, you can not memorize them, you must practice and figure out what you need to do.

In the current era, most software development companies work in a collaborative environment where several developers contribute to the same source code. While some will be fixing bugs the others would be implementing new and different features. The problem raises, how to maintain different versions of the same code base?

The delivery of high-quality code is crucial in the constantly changing world of web development, and coding standards compliance is essential. In addition to improving development productivity, writing clear,well-organized, and maintainable code guarantees the longevity and scalability of online projects. We will look at the coding standards in this blog article to make sure that high-quality code is produced in web development projects.

Code reviews have always been crucial in maintaining a standard and emphasising on the best practices of code in a project. This is not a post about how..

Object oriented programming (or OOP) is a style of programming that encapsulates data and behaviours into models known as objects. In this way, related code is grouped together and kept separate from other code, and provides reusable blocks that can be used to rationalise the problem at hand.
Java 8 stream has made my programming life simpler as a software engineer. However there are a lot more that can be improved by incorporating the RXJava library. RXJava contains tons of functionalities to process streams or observables.

One would expect that writing code which any programmer can read and understand would be an inherent skill of software developers. The fact is that only 20% of programmers have this ability. The code that you are writing must be understood not only by the machine but also by humans. In software development, quality should be everyone’s priority. Throughout the development process, the goal should be the delivery of good quality and working code.

Code reviews at Google play an important role as an engineering practice and have been adopted already in the early days of Google. Still today, they are used to keep the code base clean, coherent and to ensure no arbitrary code is committed. Even though the code review process looks similar to code reviews at Microsoft, there are some Google specifics that allow for a particular lightweight code review process.

Identifying element has always been the trickiest part and therefore require an accurate and correct approach. If you are unable to find elements by the easily available approaches like ID, class, name, link or tagname then XPath in Selenium can help rescue you. Locating dynamic elements have always been the pain area while you wish to automate the scripts, the only ray of hope to deal with such fiascos is XPath. In my current article, I will be digging into the steps of locating an element via XPath example in Selenium and its various ways.

In this short, but nonetheless useful article, I have summarized the most beneficial tips for writing clean code. These rules are independent of the language you use and are invaluable for both beginners and experienced programmers.

Just like quality assurance is done in manufacturing, testing code quality is also done in software development. While developing software or if you're inspecting code written by your team, you need to make sure you verify its quality at every level of development before it gets more complex. In the world of software, the phrase code quality can be interpreted in different ways by different industries and teams.

In the previous article, we looked at the macro trends that make tech debt inevitable. However, even though tech debt is a fact of life, technical bankruptcy doesn't have to be.

Many engineering teams are making the switch to a DevOps culture. This has a lot to do with the way the software development cycle has changed over the years. It used to take months to implement a new feature, get it through testing, fix any issues, and finally get it to production.

JavaScript is a bit confusing for developers experienced in class-based languages (like Java or C++), as it is dynamic and does not provide a class implementation per se (the class keyword is introduced in ES2015, but is syntactical sugar, JavaScript remains prototype-based).

My team at Stepsize has surveyed 200+ Engineers and published the State of Technical Debt 2021 Report that explores the impact of tech debt on companies.

Test-driven development (TDD) is all the rage these days and has been a discussion topic for quite some time. If you are brand new to TDD, this article should serve as a good introduction to what TDD is, why it’s useful, what a typical TDD workflow looks like, and when to use TDD.

Application builds when broken down into multiple smaller service components, are known as Microservices. When compared to the traditional Monolithic way, a Microservice Architecture treats each microservice as a standalone entity/module, essentially helping to ease the maintenance of its code and related infrastructure. Each microservice of an application can be written in a different technology stack, and further be deployed, optimized and managed independently.

Tech lead, team lead, software architects, and engineering managers — as any developer already knows, naming is hard. Throughout the industry, those roles are as fuzzy as their responsibilities.

In software engineering, Creational Design Patterns deal with object creation mechanisms, i.e. try to create objects in a manner suitable to the situation. The basic or ordinary form of object creation could result in design problems or added complexity to the design. In this article of the Creational Design Patterns, we’re going to take a look at the much-hated & commonly asked design pattern in a programming interview. That is Singleton Design Pattern in Modern C++ which criticizes for its extensibility & testability. I will also cover the Multiton Design Pattern which quite contrary to Singleton.

Guaranteeing code quality when your website is in the development stage is a colossal task. However, even with a steady number of programming designers, keeping up code quality can be daunting. Without code quality tools and a reliable framework, the entire task can amount to enormous technical debt, doing more harm than good in the long haul.

Data-based analysis shows that Collective Code Ownership can do harm and affected code areas can probably become hotspots of maintenance.

It's easy for technical debt to grow in our codebase. Commit to spending 20 minutes a day for 30 days to tackling technical debt and get 1% better every day.

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.

Most of what I will discuss in this article is knowledge accumulated from reading, “Functional Programming in JavaScript”, by Luis Atencio. Let’s dig right in…

Without organization, backlogs get messy quickly, and issues can’t be prioritized.

It would be way easier for managers if they could only draw a flow chart explaining how code review works. The manager then would email all the peers, telling everyone should follow the new process.

In this article, we'll discuss some basic principles of coding in python that can help you optimize your programs' performance.

High unit test code coverage is often viewed as a key indicator of code quality, but it's important to focus on the quality of the unit tests, not just the cod

Well-written multitier applications consist of multiple layers. The most widespread three-tier architecture divides our code into a presentation, business and data access tiers. Like it or not, but the business layer is where we, developers, spend the most time on a daily basis. This is the place where all processes and decisions our application depends on take place. Therefore, requirements for the business layer change more often than in any other layer. What hurts us, developers, most is that with every change, even the smallest ones, we need to recompile and rebuild our app. It usually takes a piece of the valuable time that we could use for more interesting things. What if we could move a business logic out of our code and let non-technician people change it?

Application Acceptance

The domain design approach to software development contributes to solving a specific domain model. It revolves around the business model, linking execution to key business principles.

At first glance, the question “Can you make a bug on purpose?” may seem banal. However, if you think about it, everything doesn't seem so obvious anymore.

Welcome to the Serverless world. One of the first things you’ll hear about is AWS Lambda - and you’ll continue to keep hearing about it! While architecture can be serverless without Lambdas involved, it’s very often the key component within a serverless application.

Oh! If all your code worked as it was supposed to.. Of-course you just made a tiny change and the whole system came crashing down! The existing system seems almost alive, and resists any code change by crashing! Quite often, developers declare a truce in the form of a 'code-freeze'! After a deep breath (perhaps several weeks..) the code-freeze is lifted, and the battle is renewed.

In this article, I will demonstrate the testing approach I’ve been using successfully in a project I’ve been working on for the past 8 years.

Learn practical solutions to common Python code problems related to readability and scoping.

Maintaining the same E2E coverage will require more and more tests—and their execution time will add up.

Many developers are familiar with the situation like “where did this code fragment come from and why is it needed?”. You have to spend time and deal with the details already considered by another colleague. How to make it take a less amount of time? To achieve this, pay attention to a process of writing descriptions for Pull Requests (known as “PRs”) and Merge Requests (known as “MRs”). This article will focus on the content of the PR description without any explanation of coding since each project has its own coding-related specifications and requirements.

In RSpec, there are two different ways to write DRY tests, by using before or let. Their purpose is to create variables that are common across tests. In this post, we will explore differences between before and let and explain why let is preferred by the Ruby community.

In most DevOps settings you’ll find that there are multiple environments in the pipeline. You might have conditions that change the environment based on which branch was merged or when a branch is tagged for release. There are a number of reasons you want to have more than just a production environment, the biggest reason being testing.
