Agile Tester certification exam model resolution (CTFL-AT)

Build real backend development skills with Node.js from the ground up in a practical, clear, and professional way.This course is designed to help you go from beginner to confident backend developer by mastering the full Node.js backend ecosystem. You will not only learn how to write JavaScript and TypeScript for the backend, but also understand how real backend systems work behind the scenes.We start with strong programming fundamentals using JavaScript, then move into modern ES6+ features, asynchronous programming, and TypeScript for safer and more scalable backend code. After that, you will dive deep into Node.js itself, including the runtime, modules, events, streams, buffers, error handling, and performance basics.You will also learn how backend communication really works through HTTP, REST APIs, request and response structure, status codes, API design, validation, pagination, filtering, and clean error handling. Then we move into real backend frameworks and tools used in production, including Express.js, Fastify, NestJS, and Sails.js.This course also gives you a strong database foundation. You will understand data modeling, transactions, indexing, performance thinking, and backend architecture concepts. Then you will work with PostgreSQL, MongoDB, and Prisma so you can build modern backend applications with both SQL and NoSQL approaches.By the end of this course, you will have a complete understanding of Node.js backend development, from programming basics to production-ready architecture concepts. This course is ideal for beginners, JavaScript developers moving into backend development, and developers who want one complete path to master Node.js backend engineering.You will learn:JavaScript for backend developmentModern JavaScript ES6+Asynchronous programming in Node.jsTypeScript for backend systemsNode.js internals and runtime conceptsHTTP and REST API design<

E se potessi costruire un'app iOS con Intelligenza Artificiale integrata — senza server, senza API a pagamento, senza inviare un solo dato fuori dal dispositivo?In questo corso costruirai CardLume, un'app di flashcard intelligenti che trasforma qualsiasi testo in schede di studio pronte all'uso. Incolli un testo, Apple Intelligence genera domande e risposte, tu studi. Tutto avviene direttamente sull'iPhone, offline, in totale privacy.Non è un corso teorico. In 7 lezioni pratiche, parti da un progetto Xcode vuoto e arrivi a un'app pubblicabile sull'App Store.COSA IMPARERAI:• Creare un'app iOS completa con SwiftUI e SwiftData• Usare Apple Intelligence e Foundation Models per generare contenuti on-device• Progettare modelli dati con @Model e @Relationship• Costruire interfacce moderne con NavigationStack, animazioni 3D e dark mode• Integrare l'AI on-device con LanguageModelSession e output JSON strutturato• Implementare una sessione di studio interattiva con flip animation e tracking progressi• Preparare un'app per l'App Store: icona, screenshot, descrizione, privacy policyCOME FUNZIONA IL CORSO:Ogni lezione segue il metodo Vibe Coding: ti spieghiamo cosa costruire e perché, poi ti diamo un prompt preciso da usare con Claude, Cursor o il tuo editor AI preferito. L'AI genera il codice, tu lo rivedi, lo capisci e lo esegui. È il modo in cui si costruiscono app nel 2026.PERCHÉ APPLE INTELLIGENCE:A differenza di ChatGPT, Claude API o altri servizi cloud, Apple Intelligence gira interamente sul dispositivo. Questo significa:• Zero costi API — il modello è già sull'iPhone• Zero latenza di rete — risposte in pochi secondi• Privacy totale — il testo dell'utente non lascia mai il device• Funziona offline — nessuna connessione internet richiesta<

JavaScript (JS) is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles.Three fundamental languages of the web are HTML, CSS and Javascript.Html is used for structure, CSS is used for styling and Javascript is used for functionality.Reasons to learn JavascriptNumber One - Javascript is the most popular programming language in the world.Number Two - Javascript is de facto language of the webNumber Three - Javascript is Easy to learnNumber Four - Knowing Javascript provides great opportunity to get a jobNumber Five - Javascript is Everywhere.Javascript is not web-exclusive anymore. Its on the servers (NODE.JS), cross-platform desktop-apps etc...This step by step course is intended for everyone who wants to start working with Javascript.We will cover what is Javascript, how to add Javascript to our projects, how to start working with Javascript and at the end we will make quite a few projects. A basic knowledge of HTML, CSS would be preferred.

Want to feel like an awesome spy hacker similar to the one in the movies that opens a command line terminal and manages to complete complicated tasks using a few simple codes? Well, this can be a reality using BASH. A huge chunk of a programmer’s time is wasted in trying to repeat codes and processes, especially when it comes to working with UNIX or Linux. The constant commands that are required to program or create systems is a tedious and long process. Well, here’s how you can eliminate that and save a whole buncha time – BASH Bourne Again Shell, more popularly known as BASH is a UNIX/Linux shell and a command line interpreter that runs commands from a standard input file. This shell comes with a nifty feature that allows you to reduce the amount of commands that you have to call personally by automating them. Our Shell Scripting course has been specifically designed to teach you how to use BASH to shave hours from your coding practice. Learn how to write shell scripts, learn how command history, echo command and even variables work, along with how to automate simple and complex commands. This BASH tutorial doesn’t even require you to have previously worked with BASH. All it needs is for you to be familiar with UNIX or Linux and have a machine that runs UNIX or Linux – that’s it! That’s all you need to be on your way to learning automation. The course starts at the very beginning including what is BASH, what are shells, what do you mean by shell scripts, customizing your shell, difference between a shell script and an interactive shell, command line-options, statements, loops and so much more. In addition to providing you with theoretic information about BASH and Shell Scripting, the course will also give numerous examples at every step to get you familiar with how scripting works and what happens when you execute a certain script. Additionally, you will also be provided with all t
