What is this course covering?The course covers everything you need to become a blockchain developer. Students of this course will learn what Ethereum blockchain is and how it works on the base level and from a developer's perspective.Students will learn what smart contracts are and how to create them. Smart contracts are going hand in hand with dApps(decentralized apps). The course covers them as well.The front end for dApps covered in the course use React library and Next JS framework. CSS and design are built with the help of Bulma and Tailwind frameworks.Three real-world applications are created in the course. Faucet Application: This straightforward app encompasses React JS, Solidity, and Ganache. It provides an introduction to the fundamentals.Marketplace: This advanced application involves Next JS, Solidity, and Ganache, along with deployment to an actual blockchain.Adopt Pet: A bonus section focusing on React JS, this section utilizes Hardhat to manage the smart contract and deploys it to the Polygon network.Solana NFT Minting App: This bonus section teaches you to build an NFT minting application on Solana using React, TypeScript, and the Metaplex Umi framework. You'll integrate Solana wallet adapters, create NFT metadata, and mint tokens on the Solana devnet.Every part of application creation is well explained and documented.Faucet application:The initial application in the course provides students with a hands-on experience to learn the fundamentals and core concepts of the Ethereum network.The application's frontend is developed using the React library and the Bulma framework. The Truffle development environment and Ganache (a private blockchain) are utilized for smart contract creation.The faucet application allows users to donate and withdraw funds from the smart contract. Users can interact

This course contains the use of artificial intelligence.What’s emotional intelligence about? Emotional intelligence is about using your emotions to inform your thinking and using your thinking to understand and manage your emotions.For many of us, with so many competing demands, concerns and commitments in our lives, it’s easy to feel overwhelmed and stressed, to become unsure and confused, to misunderstand or be misunderstood by others.With emotional intelligence, by understanding your emotions and how to manage them, you are better able to express how you feel, what you want and don’t want, while at the same time acknowledging and understanding how others are feeling and behaving.It’s a dynamic process; the extent to which you can understand and manage your own emotions influences your ability to understand and manage other people’s emotions. And the more you understand other people’s emotions, their intentions, motivations and behavior, the more appropriately you can respond and the more effectively you can interact with them.Emotional intelligence can help you to live and work with others more easily; forge stronger relationships, both in your personal life and at work. You are more able to sense and manage the emotional needs of others. You are more able to think before responding and know to give yourself and others time to calm down if emotions become overwhelming.Developing your emotional intelligence can help you to lead a happier life because thinking and behaving rationally and calmly in difficult situations puts you in a better position to handle feelings and situations that you may have found difficult and challenging in the past.But emotional intelligence is not only about understanding and managing difficult situations and emotions. It’s also about knowing how to engage the ‘feel good’ emotions that can give you and other people positivity, confidence, support, motivation and inspiration.

If you’re a Spring/Java programmer who wants to learn the essentials and some of the advanced topics of Spring Data JPA with Hibernate, then you’re the one this course is designed for.It uses Hibernate as the JPA provider for this course, which is also the default JPA provider of Spring Data JPA. You'll be learning the fundamentals and some of the advanced Spring Data JPA features covering Repositories, Derived Queries, Paging Sorting, Query-By-Example (QBE), Auditing, Transactions Concurrency, Modifying Queries, Projections, Mapping Associations and Mapping Inheritance.It'll be discussing some of the Best Practices and Performance Optimizations as well.Spring Data JPA provides an abstraction layer built on top of the JPA API specification, so JPA is important for this course, but even if you have just some basic experiences with JPA/Hibernate, you should not find it difficult to complete this course successfully, as it also covers the most essential topics of JPA at the end of the course in Appendix A.The course also discusses the SQL at runtime every step of the way, and the performance implications of it. There will also be Lab-Exercises and Quizzes throughout the course, to challenge you, and also to help you revise the concepts learnt in the previous sessions.MySQL and H2 in-memory database are the two RDBMS that the used in the course.

“This course contains the use of artificial intelligence”ChatGPT has moved far beyond simple chatbots and demos, but most people are still using it in ways that do not translate to real business or production environments. This course is designed to close that gap. ChatGPT for Real-World Applications: From Prompts to Production teaches you how to use ChatGPT the way it is actually applied in modern organizations — as part of reliable systems, data pipelines, and production-ready workflows.You will start by building a clear understanding of what Large Language Models (LLMs) really are, what ChatGPT can and cannot do, and why prompting alone is not enough for real-world use. From there, the course progressively moves into prompt engineering fundamentals, advanced reliability techniques, and structured prompt workflows that reduce hallucinations and inconsistent outputs.As you advance, you will learn how ChatGPT is integrated into business analytics, engineering automation, and internal tooling, including how to design prompts that support decision-making, reporting, and code assistance without introducing risk. A major focus of the course is Retrieval-Augmented Generation (RAG), where you will learn how to safely connect ChatGPT to your own data, databases, and documents so outputs are grounded, traceable, and auditable.The course then shifts into system design and architecture, teaching you how to place ChatGPT within real applications using APIs, tool-calling, and multi-step workflows. You will learn how to handle latency, cost control, scaling, and failure-tolerant design</
