Heapcon

13/05/2026

Heapcon 2026 is about more than AI.

Intelligence existed long before machines. In nature, in movement, in instinct...in the systems humans build when things get complex.

This year’s theme explores intelligence in its fullest sense. Not just what machines can do, but what understanding, intuition, and judgment still mean in the age of automation.

On November 5–6, engineers, builders, and curious minds gather again in Belgrade to explore what comes next.

AbstractionArch-v2 doesn’t trust the API.
They trust the commit that introduced it.

// temperature: 0.1
default_question: “What decision is this hiding?”

While everyone else is reading the docs, they’re reading the ADR from 2019 that explains why the docs stopped matching reality.

Some engineering talks give answers.
The best ones show where systems start fighting back.

At Heapcon 2025, Luis Serra explored what happens when Infrastructure as Code stops being tooling and starts behaving like a product.

Complexity. Testing at scale. Real tradeoffs.

That’s the kind of thinking you can expect at Heapcon 2026.

ConstraintModeler-v3 has entered the room.

The feature isn’t scoped yet, they’ve already found the failure point.

temperature: 0.2
default_question: ‘What breaks at scale?’

They’ve saved your system more than once. It just never turned into a Jira ticket.

If this is you, you know.
If not, you’ve worked with one.

Tag them - they won’t be surprised.

See you at Heapcon • Early Bird tix available!

Not a personality test. Not a framework. A mirror.

In a world where AI generates the code, the engineer who matters is the one with the sharper mental model.

This week, we start releasing them.
Six cognitive signatures, one question:

Which model are you running?

This could be you.

Heapcon 2026 Call for Speakers is open and we're looking for engineers, architects, and tech leaders who have something real to say.

Not a polished keynote, a talk that makes 700+ engineers think differently about their work.

The theme this year is Intelligence: what it means to build, decide, and lead when the machine handles the easy parts.

If you've been sitting on an idea, a hard lesson, or a perspective that the industry needs to hear, this is your stage.

Why are distributed systems so hard to manage?

According to Dejan Miličić, part of the answer lies in how we think about code itself.

In Unison, code is identified by its content, not its location.

That shift removes entire classes of problems:

– dependency conflicts
– versioning issues
– serialization complexity

This snippet comes from our most watched talk from Heapcon 2025, and for a reason.

“Just use a distributed lock.”

Works fine until it doesn’t. Then you get contention, delays, and a system that’s hard to reason about.

At some point, you stop trying to control everything and start designing for coordination.

You don't need to be the #1 expert in the room to give a great talk.

At Heapcon '25, Ties van de Ven broke down exactly what holds most engineers back from speaking at conferences and how to get past it.
