In today’s digital landscape, it’s not just about building functional systems; it’s about creating systems that scale smoothly and efficiently under demanding loads. But as many developers and architects can attest, scalability often comes with its own unique set of challenges. A seemingly minute inefficiency, when multiplied a million times over, can cause systems to grind to a halt. So, how can you ensure your applications stay fast and responsive, regardless of the demand? In this article, we’ll delve deep into the world of performance optimization for scalable systems. We’ll explore common strategies that you can weave into any codebase, be it front end or back end, regardless of the language you’re working with. These aren’t just theoretical musings; they’ve been tried and tested in some of the world’s most demanding tech environments. Having been a part of the team at Facebook, I’ve personally integrated several of these optimization techniques into products I’ve helped bring to life, including the lightweight ad creation experience in Facebook and the Meta Business Suite.

For many full-stack developers, the combination of Spring Boot and React has become a staple in building dynamic business applications. Yet, while powerful, this pairing has its set of challenges. From type-related errors to collaboration hurdles, developers often find themselves navigating a maze of everyday issues. Enter Hilla, a framework that aims to simplify this landscape. If Hilla hasn’t crossed your radar yet, this article will provide an overview of what it offers and how it can potentially streamline your development process when working with Spring Boot and React.

String reversal is a common operation in programming that involves reversing the order of characters in a given string. While it may seem like a simple task, there are various algorithms and techniques to accomplish string reversal efficiently.  Understanding these algorithms will equip you with the knowledge to manipulate and transform text in different programming contexts. This article will explore different string reversal algorithms, discuss their approaches, analyze their time and space complexities, and provide insights into choosing the most suitable algorithm for your specific requirements.

To propose an implementation, we will present a use case that allows us to define the requirements. We will describe the functional and technical context in which we will operate and then specify the requirements. Based on these requirements, we will propose a Keycloak implementation to meet them and make the necessary adaptations on the Angular and Springboot side. Environment Functional Context This concerns an accountancy firm that provides services to external clients and has employed staff to manage the files. If a customer (external user) wishes to connect, they must create an account on the Saas application. In the same manner, when the staff (internal user) desire to work on the files, they must use their Active Directory account to log in.

Accessibility means designing products, devices, services, vehicles, or environments so that they’re accessible to specially-abled people. A big part of the concept is to enable people with disabilities through assistive technologies (screen readers, keyboard detection, and other assistive technology). To create accessible things means to create something that is accessible to all (whether they have a disability or not). Users can use an application to achieve established goals with effectiveness, efficiency, and convenience and not be confused with accessibility, which is how users can use an application in a specified context.
