Free the Social Web

Social networks are a ubiquitous part of our life -- about 2/3 of all Internet users use social media platforms on a regular basis. They help us connect to family and friends, meet people from around the world who share our common interests, and read and discuss local, national and global news. But social networks have a dark side, too. Their algorithmic feeds can be psychologically addictive, and lead to anti-social behaviour that's bad for society and for our own mental health. The huge amount of data that we share with social network platforms has dubious stewardship, and is often shared with marketers to target us with ads. Most of all, the platforms are locked down, disallowing most interesting hacking, data mining, and optimization for your own use. As hackers, when we don't like how technology works, we make our own. But in the case of social software, that's not enough -- we need to keep connected to the people who matter to us, and the politicians and thinkers who shape our world. How can we make our own social software that keeps us connected to others? ActivityPub is an open web standard from the W3C. Patent- and royalty-free, collaboratively developed, it lets Free Software developers connect to commercial platforms and free ones alike. The network of ActivityPub-enabled services, dubbed the Fediverse, is a burgeoning coalition of social networks that interoperate with open standards. In this talk, Evan will give a gentle introduction to using ActivityPub-enabled services to get on the Fediverse. He'll talk about the challenges and successes of open social networks, and give some insights based on his 15+ years of building and fighting for the open social web.

What Is Free May Never Die

Software freedom grants a project functional immortality. Legal, economic, organizational, and temporal forces all conspire to destroy software going back to the dawn of recorded software history. We will explore the exact mechanisms for how the free nature of FOSS allows for unparalleled longevity, even in the face of assassination attempts from multi-billion dollar trans-national corporations. We'll look forward in time as well, and chart out a course for the future where all software is free.

Developing on Nextcloud in 2025: What's New?

This 50-minute talk will include a brief introduction to [AppAPI](https://github.com/nextcloud/app_api) and how it works, explain what "external apps" are and how they differ from traditional Nextcloud apps, as well as show some example external apps in action and their real-world use cases. We will also highlight other ways the community can contribute to the Nextcloud ecosystem as a whole through: 1) the various programming languages already in use throughout the suite of Nextcloud software, and 2) how other (under-represented) languages can be newly integrated into the app ecosystem. Afterwards, we will move into the live workshop component where we will walk through the development of a simple example app in Python. With this hands-on tutorial, our goal is to lower the entry barrier for all developers by showcasing what it is actually like to develop for Nextcloud, ultimately making it accessible to students and entry-level developers.

Linux Doesn't Resonate With The Mainstream - stillOS

This talk addresses Linux issues that prevent it from being a mainstream option like Windows and macOS currently are. I'll also demonstrate how I'm applying these lessons when building stillOS. Many people point to app compatibility issues, but I believe the real issues are closer to stability and usability problems with current Linux desktops, as well as Linux's brand reception among the mainstream audience. With that, I aim to leverage the current issues that Windows and macOS have, while also learning from their strengths to create the perfect mainstream Linux OS.

As a web developer with small children, I wanted to find a way for them to engage with computer programming concepts without having to write functions or even have to read. In collaboration with my kids I built a few simulation/games/learning tools to explore different concepts. I was heavily influenced by Bret Victor. I was also inspired by the Nand2Tetris course.

Serial Config: Compiling Applications for Embedded Interactivity

Interactivity is built into most every electronic device. (It’s unnerving when it isn’t!) Lights, screens, and chirps indicate power or status. Switches power up. Buttons and screens navigate, select, and start. Graphs show data. Menus alter settings. For many devices, interaction is the most difficult and intensive part of development. Screens need case cut-outs. Buttons need debouncing. Buzzers need pulsing. In some commercial applications, designers support interactivity with an app running on a phone or computer. Serial-config is an open source effort to bring this kind of tethered interactivity to prototypers and independent device builders. The input to serial-config is a data schema and environment specification. The schema describes the data format and kind of interaction, such as settings editing, command execution, and data streaming. The environment specification describes the language and hardware configuration (arduino/etc), storage, connection method (serial or BLE), app destination (android or desktop), and plug-ins for greater control. Serial-config outputs an embedded library that a designer builds into their device, and an application binary that supports interaction. Crucial to serial-config’s success is a low-overhead embedded command set, and a self-describing interface that reuses the application environment to specify its own input.

Learn practical skills TODAY to prepare for AI Incident Response with the AIRCTL Project

After learning how to be incident commanders, you will immediately apply the skills learned in-session to run tabletops at SeaGL with instructor-led facilitation. Participants of will attend an introductory briefing by the AIRCTL team on AI for security professionals, four common types of AI incidents, and the mechanics of the Backdoors & Breaches tabletop IR game. Participants will then form teams, get guidance for your scenario, and breakout to roleplay as an Incident Responder or Incident Commander for a facilitated playtest of one of the common AI incident scenarios: R&D compromise, material breach via AI path, AI defacement & manipulation, AI exploitation. Be prepared to commit at least one hour to the workshop session to experience all segments. The intro briefing is 10 minutes with short Q&A. Each game scenario takes 30-60 minutes for play, depending on the IR team. Debrief discussion and exit survey will take roughly 20 minutes. An optional “all hands” debrief will follow. Participants who playtest any of the AIRCTL Project IR scenarios and share their experiences and ideas as feedback will be eligible for playtester credit on the AIRCTL project pages — we want to see the community win and appreciate your time with us has value. The session will not be recorded but notes and photos with consent are welcome.

The Seattle Community Network Stack

SCN uses a lot of free and open-source software (FOSS) in our production network, often self-hosted on hardware we own, which dramatically reduces our operating costs and gives our volunteers access and exposure to more advanced functionality. Our software "stack" is dynamic and evolving, based on volunteers’ interests, capacities, and opinions on how we should operate and organize. Examples range from an internal site management VPN that helps our volunteers conduct remote troubleshooting, to a custom-written Discord bot that allows us to create and manage shared volunteer tasks in a ticketing system. At the same time, self-hosting FOSS comes with risks and responsibilities. For example, maintaining hardware redundancy, disaster recovery procedures, and data backups falls to us, a group of passionate but time-constrained volunteers. We discuss methods for managing these risks, and welcome suggestions and proposals for how to improve our processes. Our methods will be most useful for other community networks featuring similar organizational styles that seek to minimize operating costs. The time, technical labor, and expertise that our volunteers contribute allows us to save money. As a DIY "community learning network," we collectively enjoy and gain valuable experience from configuring and maintaining SCN's software stack. Doing so, and writing public documentation about it, furthers our mission of contributing technical knowledge and facilitating learning experiences for the broader public.

pkgconf: 15 years later

In April 2011, I started writing a new implementation of the venerable pkg-config utility to improve its performance and usability called pkgconf. Users around the world now interact with pkgconf on a daily basis whenever they build software as it is the defacto pkg-config implementation in almost all operating systems. Many lessons have been learned along the way. This talk is a combined retrospective as well as a look at future enhancements to the next major release series of pkgconf. In this talk, we will briefly look at legacy pkg-config, as well as the major development milestones of pkgconf, as well as a look at future improvements to the tool and surrounding ecosystem, including the introduction of a new structured data format developed in collaboration with CMake and Meson called CPS and improvements to pkgconf's SBOM generation abilities. This talk will be interesting mainly to software development practitioners and software packagers, who are the primary users of the pkg-config ecosystem.

GNU/Linux Loves All

11/8 is an ancient musical interval. This interval falls halfway in between two notes of standard 12edo tuning. From the perspective of a standard 12edo tuner, 11/8 is as out-of-tune as possible. Not only is 11/8 an acceptable note of ancient tradition and modern non-Western tradition, it sounds good to modern Western ears as well. This is because it comes from the harmonic series. A 12edo tuner is not made for harmonics. This is why it calls 11/8 out-of-tune. Limiting possible pitches to only 12edo excludes access to the harmonic series. The harmonic series is how the ear perceives music on an unconscious level. The harmonic series is how humans know what instrument is playing, whose voice is talking or sing, and the quality of tones and music. While 11/8 is ancient, the Western standard of 12edo makes it seem modern. The midi standard makes 12edo simple while making other tunings less accessible. 11/8 is not on a standard piano or keyboard. For-profit companies like to offer modern proprietary software as a "solution" to experience ancient notes on a computer or keyboard. This is quite simply not acceptable. Everyone needs to have open access to ancient notes. We should not need to turn to modern proprietary software to experience notes that are millennia old. Instead, we should use FLO software.

Do you need to search plain text files? Do you have big files? Lots of tiny files? How about inline searching of command output? Introducing "grep"!!! Find out if grep is the tool for you! Watch as your fingers never leave your hands while you slice and dice plain text! Be amazed as you quickly search through mountains of text to find what you're looking for. But, wait, there's more. There's an entire grep family of tools! * egrep for advanced regular expressions * fgrep to ditch the regular expressions * rgrep to recursively search a filesystem * pgrep to search the process table And they can combine to be more powerful than Voltron[0]!

How I used open-source tools to prove my marriage to the US Government (No Streaming)

In 2023, my American spouse and I filed for an immigrant visa to bring me to the United States. US Citizenship and Immigration Services requires spousal visa applicants to provide a variety of evidence to prove that they have a bona fide marriage - that is, that their relationship is real. It's important to present this evidence clearly, so that USCIS employees and consular officers can easily find what they're looking for. Between boarding passes, photos, and receipts - and the one constant in life, taxes - the evidence accumulated very quickly. We needed a way to keep it organised, so that we didn't overwhelm the people who had to review our application. This is where open-source tools come in. Git, LaTeX, and open-source document management utilities allowed us to store evidence as we went, and collate what we needed when it was time to submit. We even had a CI/CD pipeline, which produced clearly-labelled documents with a table of contents. Not everyone will immigrate to another country in their lifetime, but the principles and tools that we used can be applied to any situation that involves managing and collating personal data. If you'd like to do something with your photos other than letting them sit in an unused folder behind a 'Beware of the Leopard' sign, or if you've never used LaTeX and want to learn, there's something for you in our deeply technical take on an immigration story.

Migrating Distributed Systems Infrastructure to Serverless: Methodology and Insights

This talk presents a real-world case study of a widely used distributed service that successfully migrated its infrastructure orchestration from a fully managed environment to a serverless control plane—with zero downtime. We outline a structured methodology that looks at migration as a "journey" or "expedition". Charting the Course (client/service-level A/B testing, feature flagging), Blazing a Path (region selection, SLA awareness), Designing a Compass (telemetry, fallback metrics, health probes), and Reaching the Destination (scaling readiness and tuning). We’ll explore how to design A/B experiments that safely route traffic, monitor fallback rates, and measure infrastructure health using container-level telemetry. We’ll also cover how to avoid overloading downstream services by tracking 429s and designing scalable infrastructure units. As traffic grows, we show how to scale out logically and tune system parameters to handle burst patterns. We will also do demo of noisy neighbor issues that can sneak up on any multi-tenant/workload platforms. This session offers practical insights, reusable methodology, and metrics as a compass, to guide any team through a low-risk, high-impact infrastructure migration.

10 years of Reproducible Builds

This talk introduces the concept of reproducible builds, its technical underpinnings and its potentially transformative impact on software security and transparency. It is aimed at developers, security professionals and policy-makers who are concerned with enhancing trust and accountability in our software. It also provides a history of the Reproducible Builds project, which is approximately ten years old. How are we getting on? What have we got left to do? Aren't all the builds reproducible now?

No More Mystery Brownies: SBOMs, security errata, and the recipe for safer software

Software security, like food safety, shouldn't be a mystery. This talk simplifies jargon and acronyms to show how SBOMs and security documentation make protection accessible for everyone, not just big-budget enterprise teams. We'll explore practical ways to understand what's really inside your Linux systems using freely available tools and community resources. Whether you are a hobbyist running home servers, a FOSS contributor, or professional sysadmin, this talk aims to peel back the curtain on how the errata sausage is made and why, in the age of AI, it's more important than ever to read the back of the box.
