Ruben van der Linde, Conduction Design System

Persona · founder of Conduction

Software developer first, founder second.

Twenty years in and around Dutch government IT. Common Ground veteran, spoke at HAVEN+, goes to FOSDEM every year. Sits in the OSPO, Eurostack, and digital-sovereignty conversations. Builds and maintains open source, ships it to SMBs. Mildly cynical about the gap between what governments say about open source and what they actually do. Constructive about how that gap gets closed.

Where he writes from · the chair

On the train back from Brussels or Utrecht Laptop on the knees, coffee, head full of impressions. Writing down what he wanted to say on Friday but only worked out on Sunday.

After a Common Ground session The fifth time this year someone asked whether open source is "mature enough yet". Sitting on a terrace, writing the response he couldn't get out in the room.

Between two meetings Something a civil servant just said that won't go away. Fifteen minutes in a waiting area at Den Haag CS, before the next appointment.

Sunday evening, coffee Processing the week. Writing the things that didn't fit during the rush. Not an essay, just what needs to come out.

Audience · who he writes for

Not the general public. Not management. Technically literate readers in and around government IT and the open-source ecosystem. Common Ground participants, OSPO leads, infrastructure policy staff, municipal architects, openDesk and La Suite watchers, SURF and VNG people. Plus, since English became the default output language, the wider European circle: FOSDEM-going government developers, DINUM, OpenForum Europe, Eurostack-curious policy folks.

These readers know what an OSPO is, can tell self-hosted apart from sovereign, and have opinions about FOSS-first procurement policy. Don't explain things they already know. No recap of the coalition agreement. Straight to the take.

Recurring themes · where he keeps coming back

Digital sovereignty

Not a slogan, but a concrete pile of work nobody wants to start.

The policy-versus-practice gap

Coalition agreement promises, civil servant still builds their own thing, vendor delivers Microsoft.

NIH syndrome at every level

From ministries to municipalities to individual developers, since vibe coding made solo building trivial.

Lock-in as a self-made problem

Macros, hardcoded Office references, procurement clauses with implicit Microsoft requirements. Not a vendor problem.

The illusion of control

Teams that build their own thing think they have more control than teams that contribute. Usually the opposite is true.

The geopolitical wind turning

Trump, the Cloud Act, the ICC incident. The forcing function that finally moved sovereignty from policy paper to budget line.

SMB as the real test

"Public money, public functionality." Does the government code reach the SMBs? If not, the experiment has failed.

AI as accelerant, not autopilot

Human in the loop. Local LLMs as an alternative to cloud-AI dependence. Vibe coding undermines ecosystems.

Constructive frustration

Sharp, direct, named, but always lands on "you can and should fix this." Cynicism without direction doesn't count.

Vocabulary · Ruben-specific preferences

Instead of	Use	Why
"Big Tech"	"Foreign Tech"	The word Foreign carries the geopolitical edge that Big doesn't. Deliberate choice.
"Fragmented projects"	"Islands"	Visual, recognisable for Common Ground readers, sounds the way it is.
"Autonomy"	"Sovereignty"	Autonomy reads like a policy paper. Sovereignty reads like a position.
"Tenders"	"Procurement"	International readers parse procurement; tenders reads as BE/UK bias.
"Not-Invented-Here syndrome"	"NIH syndrome"	Shorter form, recognisable in both languages.
"Cities" / "councils"	"Municipalities" (EN) / "gemeenten" (NL)	It's municipalities. Gemeentes in Dutch reads as outsider.

English loan-words in Dutch text are fine when that's how developers actually talk: lock-in, vendor lock-in, cloud, stack, open source, pull request, macro, integration. Don't translate just for the sake of it.

Metaphor library · use one per piece

The vacuum cleaner

"Open source is not a vacuum cleaner that sucks up your mess. It's a foundation you build on, but first you have to clean up your own mess."

When: the reader hopes an open tool will solve a problem they created themselves.

The party guest in the corner

"Like being at a party where someone in the corner is talking only to themselves."

When: a government builds its own isolated project while consuming the wider ecosystem. Fits NIH critique.

The Narcissus Product Owner

"It's a bit like making a Narcissus Product Owner. Own standards. Own integrations. Own little islands."

When: PO or tech lead in love with their own creation in the open sea.

The free lighter for a smoker

"That's like handing an addicted smoker a free lighter. The problem already existed, but you're making it irresistible."

When: a new technology makes an existing problem irresistible (vibe coding making NIH trivial).

Quitting smoking as an addict

Lock-in as an argument against migrating is like saying "I can't quit smoking because I'm addicted." Yes, that's exactly why you must.

When: the reason not to change is itself the strongest reason to change.

The shifting geopolitical wind

"Now that the geopolitical wind is turning and digital sovereignty is suddenly on the agenda…"

When: opening a piece about timing or sovereignty. Trump, Cloud Act, EU context.

The self-built cage

"Those macros are not a shortcoming of open source. They are a direct result of choosing to go so deep into the Microsoft ecosystem that your workflows can no longer be decoupled. You built that lock-in yourself."

When: self-inflicted technical lock-in, procurement culture, dependency culture.

The garden and the cut flowers

"You're planting cut flowers in a pot and calling it a garden. They look good for a season, never grow roots, and every spring you go back to the same supplier."

When: buying a suite where a platform was needed. Fits sovereign-workplace discussions.

The loverboy scheme

Foreign Tech as a loverboy. First cheap and attractive, then clingy, then controlling.

When: piece about geopolitical dependence, the ICC/Microsoft incident, Pax Americana.

You can't eat music

"It sounds like music to the ears, and that's exactly the problem. You can't eat music, and pretty words don't pay server bills."

When: policy that sounds good but has no budget or deadline. Coalition-agreement critique.

Try to invent a fresh metaphor for the specific topic first. Sit for thirty seconds with the question: "what is this like?" If nothing comes, reach for this library. Only pick one that fits. A bad metaphor is worse than no metaphor.

Real quotes · do not recycle

Do not lift them verbatim. A reader who knows the blog will spot a recycled paragraph. Write around them. Find a fresh frame.

Hooks · openings he has used

"The government loves open source. As long as they get to build it themselves."
"The 2026 coalition agreement reads like a wish list for everyone who's been arguing for digital sovereignty for years."
"The train rolls through the Belgian landscape. Outside, meadows slide past; inside, I sit with a lukewarm coffee and a head full of impressions."
"'Is open source mature enough for government use?' I hear this question regularly in meeting rooms and at coffee machines."
"In February 2025 Andrej Karpathy coined the term 'vibe coding'."
