Building Starfinder: Professional Godot at Scale (godotfest2025)
As Godot gains traction in game development, a critical question remains: can it handle professional, large-scale production? This talk presents a case study from [Epictellers](https://www.epictellers.com/), where 30 developers are building Starfinder - a full-scale RPG. We examine the practical realities of pushing Godot beyond its traditional indie roots, sharing both the unexpected wins and the genuine challenges encountered when scaling the engine for commercial AA development. **Description:** This session provides an honest, practical look at developing a cRPG with 30 professionals using Godot. The [Epictellers](https://www.epictellers.com/) team shares their real-world experience building Starfinder, including both the surprises...
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.

From Theora to AV1: Transforming Video Workflows in Godot 4 (godotfest2025)
Godot’s video playback remains constrained by the outdated Ogg/Theora codec, limiting quality and integration. My talk introduces “Video Toolkit for Godot” (VTG), an open source extension proposing modern AV1 software decoding with cross-platform support. I’ll discuss VTG’s approach to future hardware acceleration, key design choices, and practical challenges. Attendees will see early results, with an open discussion welcomed to gather thoughts and suggestions. The built-in video playback in Godot 4 is still based on the legacy Ogg/Theora codec, and faces a few major constraints: 1. video quality and compression ratio are limited by an outdated...
PPPoE vs IPoE: A Practical Guide for ISPs (denog17)
**Is PPPoE really legacy? Is IPoE really better? And what actually happens when something breaks?** This talk takes a hands-on look at PPPoE and IPoE (DHCPv4/v6) in real ISP environments, based on actual deployments, not just specs. We’ll walk through the key operational differences that show up when things get serious: high availability, failover, MTU handling, multicast, and how dual-stack plays out in practice. We’ll also dive into the hidden pain points, like why hardware offloading fails in unexpected places, why VLAN models (N:1 vs 1:1) must be considered here, and how session state behaves when...
CGNAT scale testing using TRex (denog17)
I would like to present my testing methodology and the results of using TRex to generate "stateful" traffic for the purpose of scale testing CGNAT solutions. The main focus of the test is to determine the actual scale around Juniper's SRX solution.

Uncovering Blackholes: Advanced Detection Techniques for Complex Networks (denog17)
Blackholing events often have prolonged impacts and typically require manual intervention for recovery. Even a single occurrence is highly disruptive, frequently triggering executive-level escalations. Resolving such incidents demands top-tier expertise and often involves engagement with the vendor’s advanced technical support.
To accelerate root cause identification, we present several methods for detecting blackholing events, identifying the affected transit flows, and analyzing potential correlations. This approach aims to reduce response times and improve overall network resilience.

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...
Slow network, fast money: How Deutsche Telekom breaks the internet (denog17)
In Europe, net neutrality is a principle enshrined in EU law which states that all data on the internet should be treated equally - but what happens when large providers such as Deutsche Telekom systematically violate it with their interconnection practices? The Netzbremse project documents an alarming case: millions of Deutsche Telekom customers are experiencing artificial throttling of their connection because Telekom refuses to expand its peering capacities appropriately. As the only internet provider in Germany, users and network operators have to pay at both ends of the line to avoid congestion. The result: massive quality...
