Most developers use Spring Security every day and still can't explain how it actually works. I don't blame them. The docs are dense, the diagrams are confusing, and most tutorials just tell you to copy a SecurityConfig and hope for the best. So I recorded a full Spring Security 7 crash course - and made it free. In ~1.5 hours, you'll go from "it just works somehow" to actually understanding the internals: → The security filter chain (what really happens before your controller runs) → Form Login, end to end → Basic Auth as a stateless API → The JSESSIONID cookie and how sessions get hijacked → CSRF — what it is and when to disable it → The Authentication Manager, providers, and DAO provider → Custom users with UserDetailsService → Why your login fails even with the correct password (the password encoder trap) Built on Spring Boot 4 and Java 25. Source code and diagrams included. If you can confidently implement and explain security, you stand out — in code reviews, in interviews, and on your CV.

I’m mapping out some long-term career architecture and wanted to get the community's take. Java has survived every major tech shift over the last 30 years. But with AI-assisted coding, serverless architectures, and new frameworks popping up constantly, I'm curious about the next 15 years. If someone masters Java Full-Stack today (Java/Spring Boot + React/Angular + Cloud deployment), will that stack still "stand out" a decade and a half from now, or will it slowly fade into legacy maintenance? Where do you see the enterprise market heading?

We put a junior developer through a Java interview... with an AI interviewer 👀 New video is up. I ran a full mock interview with a community member, but the twist is the interviewer was an AI. Real questions, real pressure, real feedback at the end. We covered the stuff every junior gets asked: - The four pillars of OOP - Encapsulation and how immutability ties into it - Why the String class is immutable (it's not just performance) - ArrayList vs LinkedList and the real tradeoffs - The Stream API He held his own, but there were a couple of moments where he started rambling under pressure, which is honestly one of the most common things I see in real interviews.

Or if you've got an interview coming up, drop it below and the community will help you prep. Let's get more of you from junior to hired 🚀
