OTA stops being optional for connected products

I have been working on IoT since 2001, at ProSyst Software in Cologne. Everything we built rested on OSGi, a Java standard first published in 2000 for running software on small devices in…

What I actually took away from an MIT programme on agentic AI

For most of my career I've worked on IoT across very different industries: smart home, automotive, energy, manufacturing. The pattern I kept running into had almost nothing to do with…

150 hours. 107,000 lines of code. One person. What "vibe coding" can really do — and where it honestly hits its limits.

I can't code. Not in the classic sense — no computer science degree, no years in a dev team. I'm a dad and a product person.

What If IoT Had MCP Ten Years Ago? (And Why the Answer Is More Complicated Than You'd Think)

How to Become an AI-First Enterprise — And Why It's a Strategic Imperative

Building a CRA-Compliant EV Charging Network with Open Source: An Architecture Blueprint Using Eclipse Kanto and hawkBit

In my first two posts in this series, I made the case for why the IoT industry needs to embrace the architectural principles that OSGi pioneered 25 years ago, and why edge AI model…

Edge AI Model Lifecycle Management: The Hardest Problem Nobody's Solving Well

Why AI Makes IoT Ecosystem Collaboration Urgent Now — And What a 25-Year-Old Framework Can Teach Us

November last year, I had the privilege of speaking at The Things Conference about "Future-Proof by Design: Building IoT Solutions that Endure." The response from the audience told me I'd…

Weeks with a standpoint. One sentence from the commentary; the rest is on the week’s page.

“The AI did it” is no defence

Whoever runs an agent will have to show what it did and what it could not do; that it acted on its own will not count.

Someone else sets the end date

Whoever builds a connected product buys dependencies with an end date that someone else sets.

The clock runs at the manufacturer

The clock runs at the manufacturer, and whether its 24 hours are enough is settled earlier, in the supplier contract.

Who checks the frontier

An evaluator at the lab may find a flaw in the model. Authorising the agent that inherits it stays with the company that runs it.

One in five scales

Nearly nine in ten CEOs see value from AI, one in five US businesses with employees uses it at all, and two unrelated industrial surveys, one counting use cases and one counting organisations, both put scaled at one in five. The numbers do not contradict each other. They count different things.

What a product needs after the sale

An update path is how a connected product stays fixable and improvable after it is sold. Remote update was specified in 2000. These five show what it costs when the path is missing, when it cannot be trusted, and when it expires.

From 11 September, updates are a legal duty

Sell a machine against a twenty-year service life and you are arguing for twenty years of vulnerability handling, not five.

Standards outlive platforms

The technically better standard does not win. The one with better distribution wins.

Pricing when the AI does the work

The AI Act is here, just not the expected one

The deadlines slip while the teeth grow. Anyone reading “simplification” as “deregulation” is misreading the package.

AI-native services: sell the outcome

The real bottleneck is trust and accountability, exactly the part no model closes for you.

What works in the pilot fails afterwards on decisions that should have been made before it.

With agents, with connected products and in selling to industrial customers: who owns it, how it is updated over the years, who buys and at what price. That is what I write about.
