Holy Tech Night 2026

Hey guys,

it's that time again. After last year's successful Holy Tech Night, I thought I'd do it again. Three speakers will once again provide us with nerdy stuff for the evening, covering three different topics from the Microsoft world. During the breaks and afterwards, mulled wine and gingerbread will be available to see out the year in style.

Anyone who wants to is welcome to come in a suitable outfit. I'm sure some of you still have an ugly sweater at home. 🫣😆

Here ist the agenda:

18:00 doors open
18:15 first talk
19:00 short break
19:05 second talk
19:50 short break
20:00 third talk
20:45 networking

Our speakers and its topics this year:

Psst ... Private Local AI – Turn your Mac into a Private AI Power House

As the year winds down and things get a little quieter, it’s the perfect moment to take a fresh look at what my computer (MacMini M4) can already do. In this session, you’ll discover how to turn it into a private AI powerhouse — without cloud dependencies, subscriptions, or data leaving your device. We’ll explore Small Language Models, LM Studio, MacWhisper, and AnythingLLM, and walk through practical examples for local transcription, document analysis, and fast on-device reasoning. By the end, you’ll know exactly what to play with between Christmas and New Year.

Holy Hybrid: The Last Jedi of the Exchange World

Exchange Hybrid is more than a temporary solution. It is the strategic bridge between on-premises and the cloud. In this session, you’ll learn why hybrid setups remain relevant in 2025, the common pitfalls to avoid, and how to implement best practices for a smooth migration. We will dive into authentication, connectivity, and the future of Exchange in a cloud-first world. Perfect for IT pros who want to master the middle ground without getting lost in complexity.

Fabric IQ

With the new Fabric IQ, Microsoft is taking a big leap forward: rather than IT specialists, it is the business users who define and describe how the business works using an ontology, via entities with properties and relationships between them. They then explain to Microsoft Fabric where the relevant data can be found, and a data agent can then be used to query all aspects of the business and analyze them. And because it knows the entire business with its rules and not just one department, it can automatically make decisions that are almost as good as those made by its human colleagues. Not quite clear? No matter, this presentation has some good examples.
