AI systems have become more and more powerful, mostly absent from the public eye. But every now and then, their capabilities reach the public’s attention. This blog dives into the evolution from narrow AI, like Deep Blue and AlphaGo, to the ambitious realm of general AI. Discover how machines are moving from specialized tasks to broader cognitive abilities. #ArtificialIntelligence #MachineLearning #AI #RheinwerkComputing #RheinwerkComputingBlog Read here to explore the AI evolution: https://hubs.la/Q04cTt9L0

Accurate data exchange starts with choosing the right format. This blog post examines three common interchange formats—CSV, XML, and JSON—and explains how each is used to structure data exchanged between clients, servers, and web services. It also covers key differences in complexity, hierarchy, parsing, and validation. Read the post for a practical overview of when each format is most effective. #RheinwerkComputingBlog #WebDevelopment #JSON #XML #CSV #APIs #SoftwareDevelopment Read here. https://hubs.la/Q04cXY2g0

Over the years, operating systems have continuously received additional security features with each new release and have become more and more robust and secure. However, not only the developers at Google and Apple but also security researchers and attackers are busy, always actively working to uncover possible vulnerabilities. A look at the functions integrated out of the box shows that essential basic protection for users and data is available. So why do data breaches and security incidents keep happening, especially in the mobile world? In this blog post, we’ll cover the essential security features that the Android and iOS platforms come with out of the box. #AndriodSecurity #iOSSecurity #Authorizations #RheinwerkComputingBlog #RheinwerkComputingInfographic Read here. https://hubs.la/Q04cXRGG0

You’ve likely seen the name Rheinwerk Publishing, Inc., but you might be wondering exactly who we are. We are the independent publisher behind three distinct brands, offering three unique ways to approach skill building and career growth. Here's a quick breakdown: SAP PRESS is for SAP professionals who want deep, practical knowledge. From SAP S/4HANA and ABAP to finance, logistics, analytics, and architecture, our books are written by experts who work in the SAP ecosystem every day. Rheinwerk Computing focuses on broader tech topics beyond SAP. Think programming, software architecture, AI, cloud, security, and development best practices—skills that apply across industries and tech stacks. Rheinwerk Courses turn that knowledge into action through live, instructor-led online training. These hands-on courses are taught by SAP experts and designed to help you apply what you learn immediately. Different names, different angles—but one shared goal: helping you build real-world skills that actually stick. #SAPPRESS #RheinwerkComputing #RheinwerkCourses #TechLearning #SAPCommunity Explore our website to discover SAP-specific and general computing resources: https://hubs.la/Q04cXSRC0

How can you defend yourself against physical attacks to a Windows or Linux machine? For one, the protective functions of EFI or BIOS: UEFI Secure Boot is always enabled on modern Windows computers anyway. You should block the ability to boot from an external drive and be sure to set a master password for EFI/BIOS. However, these measures do not constitute absolute protection. In particular, you can’t prevent a hacker from simply removing the hard drive or SSD and then accessing it. This blog post discusses the topic further. #Linux #CyberSecurity #PenetrationTesting #Cryptography #RheinwerkComputingBlog Read here. https://hubs.la/Q04cY4v80

If you’ve ever wondered why Bash behaves the way it does, how to avoid the common pitfalls that trip up even experienced users, or what a script looks like beyond the classic “Hello, World,” this blog post goes far deeper than the basics. From choosing the right interpreter to writing portable scripts; from understanding chmod to building an actual backup utility, the post walks through Bash in a way that connects beginner concepts with real-world scripting habits. There’s also a key idea many overlook: how your PATH, environment, and file permissions shape the way scripts run even before Bash reads a single line. #RheinwerkComputingBlog #Bash #ShellScripting #Linux #DevOps Read the full post here: https://hubs.la/Q04cTnRG0

Most machine learning systems learn from labeled examples. Reinforcement learning takes a completely different approach: no labels, no explicit instructions. Just interaction and feedback. The system takes actions, observes outcomes, and gradually learns which behaviors lead to better results. It sounds simple, but this framework is behind some of the most significant AI breakthroughs of the past decade, from AlphaGo defeating a world Go champion to Google reducing data center cooling costs by 40% to the reinforcement learning from human feedback that shapes how modern AI assistants respond. This post from Dr. Mohammad Nauman's book, which has recently been nominated by the Independent Book Publishers Association IBPA for the best professional and technical book of 2025, covers how reinforcement learning works, where it's being applied today, and the fundamental challenges that make it one of the most interesting areas in the field.
