Built for the curious, this isn’t your average programming book—it’s nearly 500 pages of hands-on mentorship beyond coding, fusing core skills in Elixir, Ecto, and SQLite with business experience and R&D tenacity. Think of it as a $500 course distilled into one powerhouse resource, with tons of learning-by-doing, in a single project. Acquire hard skills in Elixir and database modeling with Ecto's migrations, changesets, and more, re-imagining a classic database that millions around the world have used before for learning. By fearlessly ditching the "happy path", this immersive, exploratory, memorable, project-based tutorial helps you confidently tackle real-world projects with Elixir and Ecto.

When your database outgrows simple optimizations, it's time to think bigger. Lift the Elephant goes beyond query tuning to reveal actionable strategies for scaling PostgreSQL, from partitioning to high-availability architectures. Built on lessons from scaling Hubstaff, this is your playbook for navigating the challenges of database growth.

"It’s 3 AM, your database just hit 500 connections, and everything has ground to a halt. Do you know why?"Most database outages aren't mysterious—they are architectural. Stop treating PostgreSQL as a black box and start understanding the mechanical "why" behind the engine. PostgreSQL Internals Mastery: Volume I is a modular deep dive designed for senior engineers who need to bridge the gap between writing SQL and architecting high-performance systems. From the process-per-connection model to the groundbreaking Asynchronous I/O (AIO) features of PostgreSQL 18, learn the internals that separate database architects from administrators. Don't just tune knobs; understand the machine.

This book offers a fantastic, hands-on approach to learning all about PostgreSQL's newest features, optimization techniques, and high availability solutions. It's perfect for database administrators of all experience levels!In this, book, you will discover workable answers to common problems, regardless of whether you are managing databases in simple localized settings or massive enterprise-level empires.

Stop treating PostgreSQL like slightly broken MySQL and start using it the way it was designed.

Explore the power of Rust with "Rust Projects: Write a Redis Clone". This hands-on guide takes you through building a Redis-inspired database from the ground up, introducing key programming concepts like TCP connections, the RESP protocol, and concurrency. Following the CodeCrafters challenge, this book gradually builds your skills, making complex topics accessible. Whether you're new to Rust or looking to deepen your understanding, this project-based journey offers practical, real-world insights into modern systems programming. The book contains 40% discount code for CodeCrafters.io!
