Future-Proofing Java: The Art of Crafting Resilient APIs

Designing APIs is an art, a creative exercise. Getting it right for right now is hard, getting it right for tomorrow is even harder.

This talk explored designing resilient Java APIs for upward compatibility, consumability, and flexibility.

We discussed the practicalities of ideas like encapsulation and inheritance, looked at wider elements like consistency, and effective communication of intent, and covered concepts like the Open-Closed Principle, Semantic Versioning, and other elements that are essential for seamless API evolution.

We also reviewed real-world examples, Java gotchas, the latest Java API capabilities, API Check tools, and data and looked at what Maven Central tells us about the challenge we all face (and just how good we collectively are).

Amazingly, good API design not only helps with evolving for the future, it makes the API more secure and reduces maintenance overheads - all while remaining flexible and consumable.

Time to break those bad design habits before they begin.

More tales from the Dark Side: How AI is the bad guys' new friend

The bad guys are clever, motivated, ruthless, and armed with AI. What was scary before is now "terrifying". So many new ways of tricking you: during this talk, we learned about sneaky device attacks, amazing attacks-by-post, AI's imitating your co-workers, AI being corrupted, unbelievable physical choreography manipulations, open source takeovers, and more!

Prepared to be appalled and frightened, we also learned a little about the scale of the challenge developers still face from assaults on our systems. Fainting was not allowed.

We then discovered how to fight back and how to change both your behaviour and your code to defend against these attacks.

Your destiny is clear - it’s time to become a Cyber Defender
