In this tutorial, we’ll discuss some of the design principles and patterns that have been established over time to build highly concurrent applications.

Handling concurrency in an application can be a tricky process with many potential pitfalls. A solid grasp of the fundamentals will go a long way to help minimize these issues.

You’ll understand how Go chooses to model concurrency, what issues arise from this model, and how you can compose primitives within this model to solve problems.

With this book, you'll explore the transformative world of Java 21's key feature: virtual threads.

A high available architecture is when there are a number of different components, modules, or services that work together to maintain optimal performance, irrespective of peak-time loads.

High availability (HA) is a term that refers to a system’s ability to be accessible and reliable close to 100% of the time.

Learn how to implement RAG (Retrieval Augmented Generation) from scratch, straight from a LangChain software engineer.

Your one-stop resource for gaining in-depth knowledge and hands-on applications of AI agents.

You will build projects with LLMs that will enable you to create dynamic interfaces, interact with vast amounts of text data, and even empower LLMs with the capability to browse the internet for research papers.

Learn about Elasticsearch with this comprehensive course designed for beginners, featuring both theoretical concepts and hands-on applications using Python (though applicable to any programming language). The course is structured in two parts: first covering essential Elasticsearch fundamentals including index management, document storage, text analysis, pipeline creation, search functionality, and advanced features like semantic search and embeddings; followed by a practical section where you'll build a real-world website using Elasticsearch as a search engine, working with the Astronomy Picture of the Day (APOD) dataset to implement features such as data cleaning pipelines, tokenization, pagination, and aggregations.
