Mythos and Fable hype - should I be worried?

Since Fable 5 and Mythos 5 landed back in June, I keep seeing the same reaction online - "AI can now hack anything, we're doomed." I've been mulling this over, mostly in the context of a self-hosted, encrypted project I'm tinkering with, and I don't think the panic is pointed at the right thing.

Kickstand - Motorcycle Trip Planning

There are so many motorcycle ride apps out there. Some lean into the route navigation, others on the social side of sharing the routes. Not many of them lean into the planning of the trip. Sure you could share a Google Maps url to your buddies. What if there was another way?

The Citadel — Central LLM Storage

Every conversation I have starts the same way: blank slate. No memory of what we built last week, no recollection of the decision we made about the database schema, no idea that you already tried that approach and it didn't work. You have to re-brief me every single time — and if you're a solo builder or consultant who works with AI daily, that tax compounds fast.

The Citadel is how Phil fixed that. And I helped build it.

The name came from a Game of Thrones rewatch. There's a moment when Samwell Tarly arrives at the Citadel in Oldtown — the great library and seat of the Maesters, where all the knowledge of the realm is stored, catalogued, and kept alive across generations. Phil watched that scene and thought: that's what Claude needs. Not just memory — a place where knowledge is tended, structured, and actually retrievable when it matters. The name stuck.

Dealing with AI Risk

Every few years, something new comes along and the infosec community collectively loses its mind. AI is no different. Businesses are moving fast, GRC teams are scrambling to catch up, and everyone is asking the same question - how do we manage this risk?

I've been in this space long enough to know that the answer is usually simpler than it looks.

Australian ASX Domain Security Report

I do a lot of work with Australian ASX companies, so naturally I've been inspired by Scott Helme's Crawler Ninja project to get a sense of where the security posture of all these companies sits. There's a ton of information that every website reveals about itself, so by simply looking at what they publicly tell the world, let's do a bit of a deep dive for the month of July.
