Spring Boot 4 is not a routine version bump. This migration touches platform baselines (Java/Jakarta/Servlet), dependency structure, test infrastructure, and JSON behavior — all at once. If your services are still on Spring Boot 3.x, I wrote this as a practical, production-oriented playbook to move to Spring Boot 4 safely, with explicit attention to end-of-life (EOL) risk, CVE exposure, and J...

This is lesson 14 of the Modern Angular Course. In the previous lesson, we introduced a writable signal for the search input. Now we build on that foundation by deriving filtered state with computed(), so the grid reacts automatically as the user types. In this post, we cover: Reusing the existing searchTerm writable signal Creating filteredProducts with computed() Rendering filtered r...

Many teams are still using AI like an intern. We give instructions, review every output, request fixes, and repeat. It works for quick experiments. It does not work as a long-term delivery model. As soon as AI becomes part of real software delivery, the intern model starts to crack: It does not scale It is hard to standardize It creates fragile outcomes that depend too much on constan...

This is lesson 13 of the Modern Angular Course. In the previous lesson, we used @if and @else to conditionally render UI in the product card. Now we turn to user interaction by adding a search input that stores its value in a writable signal. This post is part of the Modern Angular Course series. Check the course page for the full episode list. In this post, we cover: Adding a search ...

This is lesson 12 of the Modern Angular Course. In the previous lesson, we passed product data from the parent component to child cards using the modern input() API. Now that each card receives real product data, we can make the UI smarter by conditionally rendering parts of the template. This post is part of the Modern Angular Course series.
