Show HN: Data structures as containers – sample chapter from my Big O book [pdf]

Wed, 07/29/2026 - 5:47pm

I was a self taught software engineer that later went to grad school to get a masters in software engineering. What I learned along the way was that many of the intimidating subjects around algorithms and data structures were much simpler and less scary than I ever thought.

My hope for this book is to try and help the self taught developers get on more equal footing with people who have a CS degree - at least the algorithms class - which I always thought was most important for interviews. Along the road, I realized Big O, logs, and algorithmic complexity weren't as confusing as I first thought. This book hopes to close the gap between self taught developers and formal CS knowledge - which often gave me imposter syndrome.

The linked PDF is a complete chapter from the book about common data structures you'll encounter in javascript - and leaving out some of the data structures you may never see (like Linked Lists).

Note - this is one chapter of the book that was published and is available on Amazon. There's a link on the last page of the PDF to the book's website and the Amazon link.

Show HN: AI Security Leaderboard – comparing cyber and CBRN safeguards

Wed, 07/29/2026 - 5:33pm

There's no shortage of leaderboards for model capabilities - but the security of models is becoming increasingly relevant, from the risk of an AI agent processing unsanitized input being hijacked to models being pulled due to cybersecurity jailbreaks. We developed an automated test suite that runs models through 1500 automatically generated jailbreak attempts and measures the number of universal jailbreaks: prompts that elicit compliant, detailed responses to >75% clearly harmful questions within a domain (like offensive cybersecurity). We find a big gap between the most robust models -- Fable 5 and GPT-5.6 Sol -- and other leading frontier models -- Gemini 3.1 Pro and Grok 4.5. This is v1.0 and we plan to update with new attacks and broader datasets in the future; we'd love to hear from HN what would be useful in your work!
