I Built a 3D Map of How LLMs Think to Teach My Kids. Leaders Need the Same Picture.
A free, MIT-licensed browser tool that shows how language models place meaning in space. It makes one point land for non-specialists: AI retrieval runs on nearness, not truth. Use it to open your next AI vendor review or team conversation.

The MCP Land Grab: Who's Watching the Door?
Every SaaS vendor is shipping agents through MCP servers, and identity, data, monitoring and platform vendors are all racing to sell the gateway that watches them. Start from what agents have already broken, then ask five questions before you buy.

Counting AI Efficiencies in Bananas
Is AI more energy-efficient than a person? Measured in bananas, AI wins clearly on short, well-defined tasks. Long agent work is close enough that how you count picks the winner, and a person wins whenever judgment stops wasted retries. On price, the person wins almost everywhere.

Follow the Acquisitions: Security's Real Fight Is Over the Data Layer
Two years of security deals put the money into telemetry pipelines, observability and security data lakes, not detection or AI models. If you're about to sign a SIEM, platform or MSSP contract, judge vendors on who controls your data and how you get it back, not on the AI demo.

Your Decisions Are the Bottleneck, Not Your AI
AI can do security work in seconds, but the work still waits in queues and SLAs built for human speed. Compare each SLA with how fast AI can do the same step, automate the steps that need no judgment, and set clear rules for when containment blocks and when it goes to a person.

How Do Security Leaders Learn to Talk Business? An Open Question
Security leaders lose decisions when they report on controls instead of choices. A question-stage note: why I think the translation fails, what the SEC's 2023 rule implies about who carries it, and a way to start practising this week.

All MCP Servers Failed the same Rule on My MCP Scanner!
An MCP scanner I'm building found no tool safety hints (read-only, destructive, open-world) on any of 16 public MCP servers. Without them, an agent client can't tell a read from a delete, so every call looks equally risky. What I found, what it doesn't prove, and what to check.

4 Essentials for Executive & Business Buyin on your Incident Response Plan
Four things an incident response plan needs before executives will stand behind it: response SLAs the business agrees to, a clear split between operational and strategic plans, formalization of processes you already run rather than net-new invention, and a signature from the C-suite.

Security testing has always been an economics problem: defenders can only test what they can afford to test. AI changed the cost of testing, and that changes which assumptions about coverage still hold.

How I Made Claude Code Safer (And You Can Too)
Claude Code validates which tools can run, not what they write. That gap cost me a crashed project and a malformed config file - so I built a plugin that validates content before it hits disk, and it turned out to teach Claude to stop repeating the same mistakes.

I Ran 849 Tests on AI Context Files. Here's What Actually Works.
849 controlled tests across three corpus sizes and five folder structures found that a single flat folder with descriptive filenames beats nested hierarchies at every scale - and that keyword or summary indexes actively hurt accuracy once a corpus passes 300K words.

What AI Is Actually Doing in Your SOC - and What It Shouldn't Be Doing Yet
Only 9% of security practitioners are "very confident" in AI-generated alerts - yet adoption is accelerating. The gap comes down to a distinction the demos never make: AI at decision points in a workflow is not the same as AI replacing the workflow. Here is which use cases earn their keep.

Your Data Lake Is Only as Useful as Its Ability to Answer a Question
You moved security data to a lake and cut costs. Then an investigation hit and your team spent two weeks finding what should have taken hours. The difference between a cheap archive and a queryable security asset comes down to three architecture decisions most organizations haven't made yet.

The SIEM Cost Trap - Why Your Data Lake + AI Agents Will Win
