If you’ve ever spent two days pulling data out of an APM tool just to answer “how many virtual users should I run in my load test?”, this tutorial is for you. By the end, you’ll know how to derive eve

For many developers, the AI workflow looks something like this: write a prompt, get a response, copy what's useful, and move on. This covers a surprising range of tasks, from summarizing a document to

Large Language Models (LLMs) have fundamentally changed how we build modern software. But relying on a single AI model for every user request creates serious production risks. API outages happen. Prop

In this book, you'll build a fintech transaction ledger from scratch and progressively transform it into a production-ready DevSecOps platform. You'll also deploy it on AWS. The app processes credit a

Additive manufacturing has evolved into a cornerstone of Industry 4.0 and modern industrial production. Whether it's light-weighting aerospace turbine components, printing custom titanium medical impl

Antigravity Agent Skills are a great way to teach your AI agent a workflow once and reuse it everywhere. You write a short SKILL.md file, drop it in a folder, and the agent picks it up whenever it's r

Tracking flood risk takes one unglamorous but essential thing: clean and structured data. In this tutorial, you'll build a data pipeline yourself. You'll create a Python ETL (Extract, Transform, Load)
