A team of Dutch scientist and cloud engineers is working on Ecofed: European Cloud Services in an Open Federated Ecosystem. The objective and scope of the ECOFED project are to develop a technical framework for a more open and integrated cloud usage model. This framework will enable multiple clouds from various providers to function as a single, cohesive system, offering a European alternative to hyperscaler clouds. In this open cloud ecosystem, users can easily switch between different clouds.

Wikipedia tells us that _low-background steel_ is steel produced before the detonation of the first nuclear bombs. Yep, you guessed it, **this is a talk about Large Language Models**. LLM outputs have quickly spread like radionuclides, threatening everything from the scientific record to the existence of the Internet as we know it. In this talk I'll discuss _practical small web approaches_ that we can use to build a new Internet that doesn't suck quite so badly. There will also be memes ;-)

Have you noticed how the **good stuff** on the Internet is increasingly hidden behind bot checks, subscriptions and paywalls? And that it's getting harder and harder to find things online due to LLM pollution? Welcome to the club! You are in the right place.

In this talk I'll highlight some of the most egregious examples, consider how we can best preserve _low background information_ for future generations, and how we can use small web techniques like **self-hosted blogs and static site generators** to bootstrap a new infosphere that doesn't rely on a handful of _hyperscale operators_.

I'm particularly interested in how we can _federate and syndicate search_, learning from protocols and standards like RSS and ActivityPub. As part of the talk I'll give you some practical tools and approaches to try. If you find this interesting, consider joining us in the [SearchClub](https://matrix.to/#/#searchclub:matrix.org). **Let's have fun building the new Internet together!**

about this event: various

Did you know that if you change a single bit from 1 to 0 (or vice versa) in the first 'g' of the domain name google.com (which is 01100111 in binary) you will end up with variety of valid "bitflip" domains like coogle.com, oogle.com, & woogle.com

So what happens if you generate and register a bunch of cheap bitfliped versions of popular cloud / Saas provider domains, point them to your VPS, log all incoming requests & then forget about the whole thing for two years?

Well you will in fact receive a stiff bill, generate huge log files and eventually run out of disk space. But on the upside, you will also have collected a treasure trove of legit credentials & interesting stuff like valid OAuth refresh tokens, JWT tokens, bearers, cookies, emails, meeting invites with passwords & truckloads of internet scanner noise.

In this session we will revisit bitflip research from the last decade and weponize it. Showcase 'Certainly' a pioneering offensive / defensive tool that employs Wildcard DNS matching & on-the-fly generated SSL certificates and custom payloads for incoming requests across various protocols. All with the intention to downgrade security, harvest credentials, capture emails and replacing dependencies with custom "malicious" payloads

Sometimes ago, I embarked on a journey into the world of electronics and FPGA technology with no

prior knowledge. What began as passion for retro gaming evolved into a quest for preservation via reverse engineering and FPGA-based emulation. This presentation will share my journey, highlighting the challenges of learning Verilog, the tools, the resources, and the lessons I learned along the way. By sharing my experiences I hope to inspire others to contribute to preservation of video games.

**Abstract:**

In an era where classic arcade games risk becoming obsolete, preserving them is crucial. This presentation chronicles a journey from curiosity to creation, demonstrating how FPGAs can be used to create accurate emulator.

**Introduction to FPGAs:**

FPGAs are versatile integrated circuits that offer unparalleled flexibility for hardware design.

Unlike fixed CPUs or GPUs, FPGAs allow for reconfiguration, making them ideal for creating custom

solutions like game emulators. This section will explore the advantages of FPGA-based emulation over

traditional software emulators, and the existing plateform like the MiSTeR FPGA.

**Verilog Programming:**

Verilog is a hardware description language used for defining digital circuits in FPGAs. This

part introduces Verilog's role in designing these circuits, and how it differ to traditional

programming languages.

**Reverse Engineering PCBs:**

This segment breaks down the process of reverse engineering an arcade PCB. From

identifying components and they're connections, to reverse custom IC and schematics creation.

**Creating an arcade games core**

A case study on the creation of an arcade game FPGA core. Challenges faced during development, and specifities of arcade games emulation.

**Conclusion :**

The presentation concludes by encouraging attendees to embark on their own journey, offering practical advice and resources tofacilitate their exploration into FPGA-based gaming preservation. The goal is to inspire and equip newcomers with the knowledge and tools to preserve classic arcade games through FPGA emulation.

Security teams want to prevent incidents - but what if controlled breaking prevents catastrophic failures? Drawing from aviation safety, chaos engineering, and resilience design, discover why 'unbreakable' security comes from breaking things on purpose. Learn to transform incident culture from blame to learning, implement controlled failure practices, and build psychological safety that turns near-misses into competitive advantages.

TIC-80 fantasy console Byte Jam is a friendly competition to livecode a demo in a relaxed atmosphere.

TIC-80 fantasy console Byte Jam is a friendly competition to livecode a demo in a relaxed atmosphere. This can take an hour or more depending on the inspiration and time needed of the participants. You could follow the suggested random chosen topic or do your own thing.

TIC-80 is a fantasy console with limited resources like 240x136 pixels display, 16 color palette, 256 8x8 color sprites, 4 channel sound , etc. This gives the TIC-80 a very retro look and feel.

This byte jam is a good representation of the demoscene, where coders/hackers with very limited resources in hard or software make stunning audio and visual effects. In Europe the demoscene got status of cultural heritage in Finland, Germany and Polen and requested for Netherlands and other countries.

Want to join this ByteJ am as coder? Check with Dave / zeno4ever for the possibilities!!

Our digital communities are controlled by corporate platforms that surveil, manipulate, and arbitrarily deplatform us. We need a Bill of Digital Rights—ensuring privacy, ownership, algorithmic control, and self-governance. This talk lays out the Four Freedoms for Social Media and how open protocols like ATProtocol, ActivityPub, and Nostr make them possible. The future of social media must serve communities, not corporations—and we must demand it.

The Four Freedoms of Social Media: A Bill of Rights for Digital Communities

Just as free software has the Four Freedoms, our digital communities need Four Freedoms for Social Media—fundamental rights that ensure people, not corporations, control their online spaces. Social media today is defined by surveillance, manipulation, and arbitrary control—but it doesn’t have to be.

This talk lays out what we must demand from social protocols:

1. The Freedom to Connect – No one should be prevented from communicating or organizing due to corporate interests or government pressure.

2. The Freedom to Move – Users and communities must be able to leave one platform and take their relationships, content, and identity elsewhere.

3. The Freedom to Understand & Control Algorithms – People should know how their feeds are shaped and have the power to change them.

4. The Freedom to Self-Govern – Communities should set their own rules, rather than being subject to arbitrary moderation and deplatforming.

Technologies like AT Protocol (BlueSky), ActivityPub (the Fediverse), and Nostr offer glimpses of this future, but they must be built around these freedoms—not just as features, but as non-negotiable principles.

This talk isn’t just about what’s possible—it’s about what we must demand from the next generation of social protocols. The future of digital communities should belong to us—not corporations.
