Whether you're working on a stylized open-world game or a realistic landscape visualization, vegetation will be a major part of your application's graphics. But it's also uniquely tough to create and render: diverse habitats, delicate geometry, complex shading, and unique animation require an entire toolbox of tricks to look good. In this presentation, we'll showcase our easy and free workflows for creating 3D assets of realistic foliage and trees, reveal the most important shading tricks to get

Chaos Computer Club - recent audio-only feed ·

2025/11/11

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

IPv6 multihoming without BGP, quo vadis? (denog17)

Chaos Computer Club - recent audio-only feed ·

2025/11/11

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

Godot meets JetBrains: (godotfest2025)

Chaos Computer Club - recent audio-only feed ·

2025/11/11

JetBrains Rider is a great IDE for Godot. But how does it work? In this talk, we'll take a behind the scenes look at how we build the Godot features in Rider. We'll cover some of the challenges we've faced while creating a good user experience for Godot development in C#, GDScript and C++. We'll see how we've made it easy to debug your game, either in C# or GDScript, and tell the story of adding unit testing support through GDUnit. We'll see how we write inspections for your code, and provide code

Less is More: Modern Approaches to Low-Fi Visuals...

Chaos Computer Club - recent audio-only feed ·

2025/11/11

Many indie developers choose to use retro or low-fi graphics in their games for style, ease of development and nostalgia. Join me in this talk to learn how I have combined low-resolution dithered 3D graphics with modern rendering techniques to come up with colorful, crispy visuals for *Reconfigure*, an upcoming sci-fi FPS-puzzle-adventure. I will cover how I iteratively developed a unique visual style that combines modern possibilities with retro restrictions. How I deal with problems and

Gyms, Zoos, and Museums (godotfest2025)

Chaos Computer Club - recent audio-only feed ·

2025/11/11

Everyone always mentions that people do not read documentation. This is also the case for us as game developers. So what can we do about that? First, it is important not to force everyone to read pages and pages of documentation. Usually, only programmers and other technical folks go through all the effort of reading up on functionality. So what about artists, and designers? Thankfully, solutions already exist: Gyms, Zoos, and Museums. Let's look at examples, see how they work, how they can be

Slow network, fast money: How Deutsche Telekom breaks...

Chaos Computer Club - recent audio-only feed ·

2025/11/11

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

Chaos Computer Club - recent audio-only feed ·

2025/11/11

With NIS2, ISO 27001 and requirements of BNetzA raising the bar for security and operational compliance, many internet providers are asking the same question: *How do we meet these requirements without drowning in bureaucracy?* This talk bridges the gap between regulation and real-world implementation. Instead of focusing on theory or checklists, we’ll look at how to integrate compliance into the day-to-day work of running a network—with minimal friction. **Topics include:** - Turning compliance

Baremetal Server Management with Redfish (denog17)

Chaos Computer Club - recent audio-only feed ·

2025/11/11

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

The return of EGP or the curious case of the BGP...

Chaos Computer Club - recent audio-only feed ·

2025/11/11

The BGP Origin attribute has been around for decades and did not attract much attention. It is simply there, shown either as "?" for "incomplete" or as "i" for IGP. During writing slides for my BGP training I found a large number (868) of prefixes in the global routing table tagged with "e" for EGP. The presentation does not give any answers but simply raises the question who and why is playing with that attribute.

Chaos Computer Club - recent audio-only feed ·

2025/11/11

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
