Keeper to Keepers: Adding Multiplayer to Dome Keeper (godotfest2025)
The age-old wisdom for adding multiplayer to a complex single player game is: Don't.
This talk will cover how we added mixed local and online multiplayer to an existing codebase of tens of thousands of lines of GDScript and how you can think about systems in your game to do the same.

Art Direction Crash Course (for non-artists) (godotfest2025)
A talk aimed at non-artists that covers "how to art direct". We will cover basics like lighting, colors and shape language. But also teach how to stylize, what the difference between a moodboard and a reference board is and just general art knowledge that will be helpful for programmers, gamedesigners and leveldesigners.

Don't ship the wrong game! (godotfest2025)
Shipping a good game that no one desires is a sad affair. It's also easy to accidentally make a production too large. I'll share how we avoid this by building many prototypes, evaluating them against real people and then go into an appropriately scoped production, staying happy devs in rough times. Maybe most importantly, i'll share how we validate prototypes to find the games with potential among the crowd, as it's simply not something predictable or plannable.

You can’t just model a train in Netbox: About Architecting and running modern IT Infrastructure in Trains (denog17)
At DB Fernverkehr, we are running some IT Infrastructure on a large fleet of ICE Trains. In the past, there was only WIFI for the passengers, and many systems were handled as “embedded systems”. Nowadays, more aspects of “modern IT infrastructure” are part of the IT in trains, providing additional services like passenger information. This talk gives a quick introduction of what is happening on the trains, as well as some of the challenges compared to infrastructure built in data centers: How to get proper internet on the train? How can a network look like?...
IPv6 multihoming without BGP, quo vadis? (denog17)
Well, there's always NAT, or NPT. But that's supposed to be the *dark ages* 20th century IPv4 solution. So how do you do it *nicely* in IPv6? The "nicest" possible approach seems to be dst-src routing (aka SADR, aka sourcedest) — this talk summarizes the situation before diving into that solution. You will hopefully come away with an understanding of how this isn't policy routing, what router features are still spotty, what RFC 6724 "rule 5.5" and RFC 8028 are, and why a Linux based system is simultaneously the best router and the worst end...
A Peek Under the Hood: Technical Learnings from Halls of Torment (godotfest2025)
The development of Halls of Torment has taught us many lessons about making commercial games in Godot. In this talk we will take a deep dive into the games' code and share our learnings about project structure, programming patterns, performance profiling, and many other technical topics. With Halls of Torment being our first Godot-based commercial project we've had to figure out how to accommodate all of our technical requirements in a timely manner. We've made a lot of mistakes, learned many lessons, and found a couple of best practices that we want to expand upon...
The Asian internet - A guide for the uninitiated (denog17)
The Internet is not the same everywhere. And in Asia, the world’s most populous region with some of the fastest growing economies, it can be especially complex. Join Telstra to learn about how differently the Internet operates in Asia compared to Europe and North America, how those behaviour are likely to change as the impact of new AI workloads is felt across global networks, and what variables you need to think about when architecting your own network so that your company can make the most of the huge market opportunity Asia offers. This talk will...
GdUnit4 live demo + technical overview (godotfest2025)
See how professional testing fits naturally into Godot. In this fast‑paced live demo, Mike Schulze (creator of GdUnit4) writes and runs tests for gameplay logic and scenes, showcasing fluent assertions, scene runners, and tight editor integration - so you can iterate faster with confidence.
You’ll learn practical patterns for keeping projects shippable: structuring test suites, isolating dependencies, and wiring tests into CI to catch regressions early. Walk away with a clear checklist to bring robust, maintainable testing to your next Godot game.

Baremetal Server Management with Redfish (denog17)
Managing bare metal servers has always been quite time-consuming and prone to errors. Manual steps are required to configure the BMC, adjust BIOS settings, and, if necessary, perform firmware updates. If you have many servers to manage, you have to repeat everything on each individual server which likely to cause errors and diverging configurations. We have been working for some time to automate all of this with Redfish. OpenStack Ironic helps with this, among other things, but it does not work out-of-the-box with all hardware. Unfortunately, most manufacturers believe that the Redfish standard should be...
An introduction to qGIS for current Google Earth Users (denog17)
The defacto standard in network planning is to use Google Earth for dealing with a large collection of kmz and kml files that are provided by partners. Sadly this can quickly introduce spontaneous combustion of your computer or at least of google earth, as the data collection can grow quite quickly and that software as probably never meant to deal with such an enourmous amount of geodata. Luckliy there is a widely adopted open source GIS software called qGIS that can help with exploring large amounts of data. I will give a quick intro what...
