Does this mean the Commandant gets his house back?

If you're having trouble imagining this, good news! Someone did it for you already.

All this talk about refunds, but here's my question:

Companies want their refunds, sure, but when they passed those extra costs on to the customers, do we get refunds too?

Nope.

Wow! This dude could probably figure out my bank account number from my YouTube recordings or something.

Testing Codex 5.3 this weekend by building:

- An e-ink display to show me critical stats and charts for my home's solar power production
- Updates to my D&D app. Upload a session recording, get a transcription, in-character journal, session recap, knowledge compendium, and publish to the web.

I don't normally promote vendor talks, but this one will have some very practical ways to apply #AI to solve real #cybersecurity challenges, including my own agentic #ThreatHunting assistant.

Forget #Moltbook. I propose Molt Overflow.

Stack Molterflow?

Stack Overmolt?

Whatever. Let the agents share programming tips, many of which will be inefficient or just plain wrong, but will no doubt be copied verbatim into code anyway.

That's what they *should* look like.

On the other hand, if you're unprepared, this is what they actually look like:

We did a haunted hayride through the woods a couple of years ago. They used these, and literally NO ONE guessed they were whistles. They're scary as hell.

I work for Cisco Foundation AI, figuring out how to make AI useful for security, rather than just throwing AI at a problem and hoping it magically gets better.

If you want to see some of the things we're working on, this is the session for you.

Spent my day off creating an AI-assisted web app to convert recordings of D&D sessions into transcripts and in-character journal entries for the party's adventure log.

In case you're wondering if I'm a nerd as well as a geek.

I am just now coming to the realization that all those holodeck "programs" were in fact vibe-coded.

GitHub - DavidJBianco/MCP-Remixer: An MCP proxy that allows you to "remix" the tools available in the proxied servers An MCP proxy that allows you to "remix" the tools available in the proxied servers - DavidJBianco/MCP-Remixer

A personal project I've been working on: MCP Remixer, server that proxies requests to other MCP servers. It allows you to:

- Aggregate multiple servers into one
- Add new tools or suppress existing tools
- Log every request from the MCP client and the servers' responses

If my job were a D&D class, I'd probably be an Artificer, subclass Cybersecurity. I spend a lot of time coming up with new prototypes to apply AI to solve security challenges and figuring out ways to do that better.

What would yours be?

Crazy sitting-in-the-airport thought: prompt injection is to llms as code-is-data is to the von Neumann computer architecture. We got so used to it that we barely notice it anymore even though it's a major underlying factor of security issues. Prompt injection ain't going away.
