Program

Many NLP projects that depend upon the analysis of documents are impaired by the difficulty of transforming source material into a computer-readable format. For example, PDF files are designed for human consumption but can look like a bag full of words to a computer.
To address this problem engineers at Sorcero developed Ingestum, a library that is used to "devour" content sources, outputting a format that can be used for additional processing.
Ingestum has four main concepts:

• Sources - common content sources that feed the ingestion process, e.g. PDF, HTML, PNG, WAV, Twitter, email, et al.
• Documents - the intermediary and final states of a source during the ingestion process.
• Transformers - a transformation function that can be applied a document, e.g. removing hyphens from a text document.
• Conditionals - a logic conditional operation that can be use to modify the behavior of a transformer.

What if everyone had free access to a repair manual for everything they owned? Making repair accessible to everyone is the best shot we’ve got at reducing e-waste and starting to make our high-tech lives sustainable.
Right to repair is working to make that happen--to restore a small amount of freedom to the hardware world. We've introduced legislation in over 20 states and are pushing manufacturers to release schematics and security patches for embedded systems.
Learn the latest in the fight from one of the leaders of the movement. We're also in the midst of a big fight over the most evil section of the DMCA, the dreaded Section 1201 that bans breaking encryption on hardware that you rightfully own.

Jami is free software for universal communication which respects the freedoms and privacy of its users. Jami is an official GNU package with a main goal of providing a framework for virtual communications, along with a series of end-user applications for audio/video calling and conferencing, text messaging, and file transfer.
With the outbreak of the COVID-19 pandemic, working from home has become the norm for many workers around the world. More and more people are using videoconferencing tools to work or communicate with their loved ones. The emergence of these tools has been followed by many questions and scandals concerning the privacy and freedom of users.
This talk gives an introduction to Jami, a free/libre, truly distributed, and peer-to-peer solution, and explains why and how it differs from all other existing solutions and how it empowers users.

An information theoretic model of privacy and security metrics
- or - how I learned to stop worrying about password meters and love the dice

Since 2010, EFF has maintained a project dubbed Panopticlick, which aims to help users understand a technique called browser fingerprinting. Web trackers are able to stitch together little bits of information the users browser leaves behind into a cohesive whole, a fingerprint which follows them across their usage of the Web. Panopticlick is able to quantify the amount of information your browser leaks through the use of an information theoretical approach to privacy which determines how much information each individual metric (say, a user's list of fonts) reveals, and the relationship of these individual metrics to how much a browser reveals in general. Many of the misconceptions users have when using the site reflect an unclear picture about how their browser fingerprint is arrived at, and often leads users down a path that *decreases* their overall privacy in an attempt to increase it.

Adopting free software ideals can be confusing and challenging for individuals, filled with cognitive dissonance and questioning of practicality. Am I a bad person if I use nonfree software? What example should I set as a free software activist or advocate? How does that relate to responsibilities of developers and distributors?

This is a talk about practical ethics and ideals. It is personal, drawing upon my experiences and evolution over the past fifteen years. It contains some awkward discussions that free software activists like to avoid, and hopes to guide those seeking to adopt more free software ideals, but fear they may not be able to meet such high standards. It's a talk about evolution and growth.

But complacency in the face of conflict can also dilute our ideals. So this is also a talk about balancing ideals in the context of one's own unique circumstances, while at the same time preserving a strong message about software freedom.

Technopolice is a French movement aiming to analyze and document the spread of surveillance technologies in our cities and lives, in order to defend civil rights and liberties. The movement was initiated by La Quadrature du Net in 2019, and was followed by other organizations and individuals in a decentralized way. In this talk we will go through:

• one year of study and activism in the Technopolice movement;
• how we collectively gather information on these ongoning projects;
• how we legally, technically, ethically and socially analyze and debate on them;
• how we try to make them visible and understandable to non-technical users;
• how people, artists, activists, and citizens can resist;
• how we can all spread the word, that this is not our future, and not the one that we have chosen;
• how we value freedom, transparency, ethics;
• how we value common goods and that our future is ours to build.

Learn regular expressions (regex).
No prior knowledge of regex required.

Regex is a pattern matching language.
It uses sequences of characters to define a search pattern for text.

Many command line tools support regex.
Programming languages and database query languages also support regex.
Some web apps such as Elasticsearch also support regex.

This workshop introduces concepts, syntax, and language used in regex.
Labs give attendees hands-on opportunity to experiment with regex.

The workshop primarily uses extended regex on the command line.
It also touches on basic and Perl Compatible Regular Expressions (PCRE).

Common tools such as grep, sed and awk will provide conduits for learning regular expressions.

Attendees will learn:

• regex concepts
• symbols used by regex
• how to search for text
• how to capture and replace text
• character classes
• grouping
• anchoring

In past decades, free software has played a key role towards the free and trusted Internet. In recent years, free software processor projects like RISC-V have pushed forward to construct free devices and computers. However, the radio connectivity of the device still relies on the black box silicons (WiFi, BLE, cellular chips). The Openwifi project (https://github.com/open-sdr/openwifi) aims to offer an free WiFi chip design that could act as the missing piece of the free software and hardware puzzle. As the initial step, the Openwifi project has implemented the 802.11a/g full-stack on an FPGA-based software defined radio (SDR) platform. The 802.11n feature is funded by NLnet and is under development. This presentation will give you the project overview and discuss the future of the project.

Organizational change is never easy. It can be particularly challenging in values-centered non-profits, where calls for healthy organizational change can be seen as criticism or a threat to the core values. This conversation between two long-time nonprofit leaders will dive into organizational change at two tech- and values-centered nonprofits, the Sunlight Foundation (where former leaders were accused of sexual harassment) and at the Wikimedia Foundation (where a sweeping strategic process has resulted in a broader vision that goes beyond free licensing to explicitly include equity). By seeing how one organization tried to rebuild after crisis, and another proactively reimagined its role in the broader free ecosystem, attendees should come away with ideas for how their own communities (small and large) can address the past and look towards the future.

In the current digital era, knowledge systems are available and accessible in many forms digitally, making learning a easier process for almost everyone who has access to them. For instance, a primary school student is able to work on electronics, robotics, and programming. On the flipside, there are underprivileged students who do not have access to even a basic computer due to lack of IT infrastructure in their schools. This creates a digital divide.

To bridge the divide, we can use free software like GNU/Linux, free hardware designs, and freely licensed educational materials. The BalaSwecha project makes use of all these to develop a GNU/Linux distribution based on interactive learning principles for children studying in underprivileged and underfunded schools. The presentation will deal about details and execution of this community project.

Over 100 teams attempted to create free/libre solutions to address the shortage of ventilators caused by the COVID-19 pandemic; we created a large spreadsheet evaluating all of them along many coordinates. Slowly, teams coalesced into a global community and began cooperating. There were many successes, failures, and learnings. The community had pioneered techniques that were re-used inconsistently to organize teams. The overall effect was mixed in terms of its success developing ventilators, but very successful in advancing the global free hardware community. We present this story from the point of view of a full-time active participant in many organizations.

Free software licensing can be tiresome. But setting the conditions for the use and reuse of your code is extremely important. To make developers' lives easier, there is the REUSE initiative. This presentation will explain simple yet powerful best practices for defining licenses and copyright holders.

In three easy steps, you can make sure that for all files are labelled clearly. No matter how complex you project is, REUSE keeps you covered. With the additional documents and tools, you can increase the time you actually can concentrate on coding.

Join the session to learn about the principles and see a live demo of how we make a project REUSE compliant.

Your data is essential to your life, your agency, and your future. Come learn how to save, serve, and safely share your data at home with a smorgasbord of free software. I'll cover rapid setup and basic use of tools such as Traefik, Pi-Hole, Nextcloud, BackupPC, Wallabag, Jellyfin, Wordpress, and more. With these tools you can collaboratively edit documents in realtime online, stream music and video, and future-proof your digital assets.

Framasoft is a small, French nonprofit, made up of only thirty-five members and ten employees.

We've been promoting free/libre software and its culture for more than fifteen years. From a collaborative free software directory to a publishing house, from hosting more than thirty-five free/libre services (our Dégooglify the Internet campaign) to initiating a libre hosts collective (CHATONS), from PeerTube (free and federated alternative to YouTube) to Mobilizon (same, but for Facebook groups and events)...

We've tried a lot of things to help change the world, one byte at the time!

We want to share our experience outside of French boarders, so it can be studied and (hopefully) copied and adapted to other languages and cultures.

The struggle for the freedom of Internet is ever growing. Corporations, and their partner in crime, governments, come up with new clever ideas to restrict free flow of information. Overlords of the truth are trying to recover old control, which the Internet has eroded everywhere in favor of the people.
Networking and freedom of communication are meant to be great equalizers. That would be true if carriers of communication signals could come out of thin air. Like the land and means of production, our signals depend on existing infrastructure, and the lords who own them are an obstacle to the freedom of the people. Freifunk is a non-commercial, grassroots initiative to support free computer networks in the German region. We try to apply the same principles in Turkey, bringing power back to the people.

FUD fighting on the front lines of right to repair: As our homes, workplaces and public spaces fill with Internet-connected "smart" stuff, a digital right to repair is critical to protecting consumer rights, property rights and civil liberties. Despite that, electronics giants like Apple, Samsung, LG and General Electric have snuffed out scores of proposed state laws seeking to create such a right. How? By scaring legislators with tales of device hacking, cyber stalking and identity theft.

Creating a legal right to repair our stuff means short-circuiting these arguments and injecting a dose of facts into hearings and public debate. In this presentation, Paul Roberts, the founder of SecuRepairs, provides a dispatch from the front lines of right to repair and how his group of more than 200 IT and information security professionals is doing battle to set the record straight on cybersecurity and the right to repair.

SecureDrop is a whistleblowing platform originally created in 2012 for journalists to accept leaked documents safely from anonymous sources. It's used by dozens of news organizations including The Guardian, The Washington Post and The New York Times. This talk introduces the SecureDrop Workstation, the next-generation platform aimed at helping journalists communicate with sources in a high-security environment. Based on Qubes OS, the SecureDrop Workstation leverages Xen hypervisor isolation to manage sensitive source material safely, including viewing, archiving, and processing documents. The talk will review the results of the recent security audit focusing on the Workstation, and outline future directions for the project as it approaches general availability.

The labor movement and free software are natural complements to one another. Both rely on (often decentralized) groups of workers that commit to a higher purpose in the pursuit of building something that will advance people on a larger scale. I’ll discuss the ways that values of free software and labor movements complement one another. I will outline the practical technology needs of labor organizations that could be met by free software. Finally I will talk about what attendees can do to support labor movements with free software by describing some promising organizations looking to bridge the gap.

So many repetitive conversations? No forward movement? Everyone getting along mostly, but not sure how to be decisive without clear hierarchy? What could legitimate authorization look like in a decentralized world anyway? This talk touches on specific steps anyone can take.

This session will briefly address why free software is important in education and provide examples of how proprietary software is rapidly deployed in schools.
This presentation aims to help people:
- rise up against this injustice, big and small,
- share time and resources which will be shared by and for participants,
- provide a safe discussion space to address issues in education,
- generate ideas for how to become active in their community to be included in an Action Guide,
- connect with others who are interested in helping the cause for free software in education spheres.
