Software tools change fast and keeping up with them can be a challenge. This bundle brings together three practical guides covering modern Python, JavaScript and Linux tooling in 2026. Learn how today’s tools work, why developers use them and how they fit into real projects. From package managers and testing tools to build systems, command line utilities and production workflows, these books give you a practical look at the tools that can make your work faster, cleaner and easier.

Claude Code is changing the way developers build and understand software, but getting real value from it takes more than asking it to write code. This three-book bundle shows you how to use Claude Code from the ground up, build production-ready full-stack applications and work with existing software systems through practical reverse engineering workflows. With hands-on projects, real-world techniques and a strong focus on good engineering practices, this collection gives you the skills to use Claude Code confidently across the full software development lifecycle.

Seventeen books, one rule: nothing asserted, everything demonstrated — build it, break it, check it yourself.

Almost everything written about large language models is advice. This series measures it. Nine volumes, 609 pages, built and run on a single CPU core with no access to a large model —and that constraint produced the method rather than limiting it. Several results contradictedthe advice they were testing: hybrid retrieval lost in every condition, neither reranker beatthe noise floor, and unstructured pruning saved not one byte. One experiment turned out to be confounded. It is in the book alongside its correction, becausethe mistake was more instructive than the finding.

Expand your .NET skills with five in-depth books covering C#, Visual Basic .NET, PowerShell, F# and G#.
