This talk is suited for people who are interested in games, data driven visualisation, and bringing academic work to the general public, policy and practitioners. Imagine an augmented reality game, a mix between something like Township or SimCity and Ingress or Pokemon Go, with a visual style similar to the Lumino City game. Imagine a building game that uses real cities and real challenges – like the recent water crisis in Cape Town, where real resource limitations need to be managed. The game can start from a blank start to build your city or start with what exists in reality and modify it in certain ways (utopia or apocalypse) and play with what happens due to your decisions. https://aquasavvy.co.za/augmented-reality-game-for-citizen-scientists/ This would need a lot of different initiatives, data libraries etc to fit together well. Debian has experience in how very many different things fit together, and have experience in how different licensing options interface (or not), and maybe I can help improve this. In this talk I will show what I try to do and what information I have found so far. I may show prototypes and what I have found in the Debian space, and probably have a whole lot of questions for the audience. I am just venturing into this and using the talk to give a deadline to my early research, so very much a work in progress. Help, comments, critique, co-presenters welcome. I may link more strongly to a related academic initiative, Metabolism of Cities, e.g. https://prototype.metabolismofcities.org/cities/cape-town/sectors/water/ Long talk (45 minutes) Bernelle Verster True DebConf Video License (MIT-like) /talks/111-the-metaverse-gaming-and-the-metabolism-of-cities/ https://debconf19.debconf.org/talks/111-the-metaverse-gaming-and-the-metabolism-of-cities/ 2019-07-20T13:30:00-03:00 13:30 00:45 Auditório Social context & community Have you already heard about Open Educational Resources (OER)? Do you know how an Open License works? In this talk, we will discuss those topics and learn more about why those things are so important for education. This talk is built for anyone who wants to get more involved with open education and wish to apply its concepts for any material under open licenses. We will take a brief look at the history of the Open Educational Resources and the open licenses (specifically Creative Commons), we will discuss the results of a survey with future teachers about their previous knowledge about OER and Open licenses, and we will talk about how we can change this scenario.

Oddly, some proposed mitigations that require installing proprietary blobs have not caused similar worries, despite growing awareness about prevalent data collection, built-in backdoors and the risks of placing too much trust in software and hardware designers with interests not aligned with those of users. Whom can we trust, then? What lessons are there for the Free Software community? Being suspicious of Web blobs and foggy computing, and not victimizing anyone through them, do we have anything to fear but fear itself?

Em particular, traremos um estudo de caso do FLUSP (FLOSS at USP), um grupo universitário sediado no Centro de Competência de Software Livre (CCSL). O FLUSP é um grupo de extensão do IME-USP, que, tal como outros grupos de extensão, visa incentivar os estudantes a buscarem conhecimentos além daqueles oferecidos pela grade curricular. Com o objetivo de encorajar a participação brasileira no cenário internacional de desenvolvimento de projetos FLOSS, o FLUSP já vem contribuindo com projetos como Kernel Linux, Git e GCC. Assim, com base nessa experiência, abordaremos como a inserção e participação nestas grandes comunidades de software livre foi facilitada pelo trabalho em conjunto, e as vantagens de se ter um amparo local ao se contribuir com FLOSS. Trazendo o exemplo do FLUSP, será discorrido assuntos como os benefícios de reuniões presenciais semanais, a importância da programação em pares, o objetivo de sempre passar o conhecimento a frente e meios para mobilizar novos contribuidores como: organização de installfests, palestras e hackathons. Falaremos mais especificamente, também, sobre a formação de grupos FLOSS no ambiente universitário, abordando a participação do corpo docente, a parceria com disciplinas semestrais e burocracias envolvidas no processo. Por fim, apresentaremos alguns dos resultados obtidos: discussão e construção de contribuições em equipe, os projetos que já receberam contribuições do grupo e os tipos de contribuições, desdobramentos em trabalhos de conclusão de curso, e participações em programas como Outreachy e GSoC. Portanto, se você pensa em se juntar a uma comunidade FLOSS, ou gostaria de fundar uma, esta é uma conversa para você.

Um de seus pilares é a disponibilidade de plataformas abertas e acessíveis, tais como os Single Board Computers (SBCs). Essa talk irá apresentar o programa Caninos Loucos, que projeta e desenvolve SBCs brasileiros, abertos, e a preços acessíveis, ideais para uso em diversas aplicações IoT. Nela você irá conhecer a história do Caninos Loucos, os produtos desenvolvidos até o momento, e a nossa visão de futuro. Seja no campo maker ou de negócios, você está convidado a conhecer, experimentar e buscar aplicações para a plataforma brasileira oficial de Internet das Coisas.

Desta forma, a adoção de mídias de instalação personalizadas tem sido amplamente utilizada, através da criação de um live-CD responsável pela automatização do processo exigindo interação mínima do usuário. Na palestra, descreveremos o processo de utilização desta filosofia para instalação automatizada do Sistema Operacional Debian nos ATMs (Agências da Caixa Econômica Federal) e TFLs (Terminais Financeiros das Lotéricas da CEF). Por fim, foi elaborado um sistema web em Python para realizar as tarefas de automação necessárias, com essa aplicação é possível realizar os recoverys das máquinas, geração de imagens e escolha de pacotes, manutenção remota nos ATMs, consulta de logs, além de ser possível executar qualquer comando diretamente no terminal da máquina.

Our main goal is to maintain official Debian images for the cloud and some cloud-related packages. During this period we have achieved many improvements but we still have a lot of work to do and things to discuss. Cloud environment changes rapidly which does not always fit Debian release model. In order to cope with some of these changes and better support our users in cloud environments, we've been lately changing the team structure and some processes. We're getting more formalized, taking more responsibilities and cooperating more with SPI. We'd like to present to the wider public what we already did and our current and next steps, and what we have in store for the Buster release! We'd also like to collect feedback from the Debian community as it is really important and should help us in making decisions for the future of Debian in the Cloud.

It is the fiftieth anniversary of Unix, the Internet, Woodstock, the LGBTQ movement in the USA, and Linus' birthday. 1994 was the year that V1.0 of the Linux kernel was released, the Linux/Alpha project started, and Beowulf High Performance Computers were invented. 1999 (twenty years ago) the Linux Terminal Server Project (LTSP) was started, and the Linux Professional Institute was formed. Many of these projects had a fundamental change to computing, and this talk will discuss what some of those changes were and why they are important even today.

This allows us to provide two security properties: The detection of targeted backdoors introduced by a malicious archive and the validation of the reproducible builds property. We present an overview of the architecture and report on the progress made since DebConf18, which includes: - (almost) removing online operations for the client - secured mirror available - compatibility to Certificate Transparency gossip hub to defend against equivocation attacks There are also lots of things that still need to be done, and we will talk about that as well!

Without the proper references, teachers or colleagues to engage in a different topic, students may not follow that idea. One way of solving this is to find other students (and even teachers) with common interests to start developing extra curricular activities. This is how Enigma was created, a study group about privacy, cryptography and security at the University of Campinas (Brazil). In this talk, I will give an overview of the experience, share lessons learned, and discuss best practices based on the audience's experiences as well.

It’s been 6 years since Reproducible Builds were first introduced to the Debian community at large at DebConf13 in Vaumarcus and much progress has been achieved since, yet the buster release has not really achieved reproducible builds. In this talk we will explain the current status, explain what's missing and hopefully present workable ideas how to improve things for bullseye.

First, we discussed moving our packaging to Git repositories on salsa.debian.org presumably as a matter of policy. Second we discussed moving away from source packages and to a model where `git push` is used to upload packages. This is a requirements collecting BOF for that discussion. We'll discuss what people would like out of such and experience, how we might meet those requirements, and problems meeting the requirements. Deciding whether to make this changes is out of scope: that belongs on our mailing lists. But if we were going to do it, what would people want? That belongs here. Requirements will be conflicting. Choosing which conflicting requirements to meet is out of scope beyond noting the conflict. This is a brainstorming session.

Our final objective is to use this information for the quality assessment of Debian maintainer scripts. The technique of symbolic execution consists in following all the possible execution paths of a script, while recording in a symbolic form the interaction with the file system. The symbolic form (technically a formula in some logical formalism) describes the modification of the file system performed by the script on any initial file hierarchy. For the moment we have used these symbolic descriptions to extract cases in which a script may fail. Plans for future work include analyzing the symbolic descriptions in order to decide properties like idempotency of scripts, or relations between scripts like that their order of execution is independent, or that one script undoes the effect of an other script. Our analysis applies to an abstraction of *nix file systems, and also abstracts away from some aspects of scripts, in particular from tools that operate on the contents of files. Despite these limitations we have already some first interesting results. It is important to remember, however, that a possible error case detected by our tool is not automatically a bug, not only because of possible false positives of our tool, but also because it may be the right decision of a maintainer to make their script fail in case it encounters a situation it cannot cope with. We hope to have some discussion with the audience about how one can decide whether a failure is a bug or not. This work is part of the ongoing CoLiS project which aims at applying formal methods to the quality assessment of Debian maintainer scripts. Previous results on the syntactic analysis of maintainer scripts had been presented at Debconf18. This is joint work with Benedikt Becker, Claude Marché, Mihaela Sighireanu and Yann Regis-Gianas from our research teams in Saclay and Paris.

We now have it up and running, on 3 different architectures. Let's celebrate that. Some topics to discuss: - why did it take so long? - how does it work? - what are the implications? - should you trust it? - what happens next?

There also have been many people who have submitted bugs and patches, for which I'm very thankful too. But, the everyday maintenance of the piuparts.debian.org service is on my shoulders, I'm deploying changes and I'm deciding what code to merge and deploy. This works nicely but has become boring and tedious too. Recently I have asked for i386 piuparts-slaves to be provided by DSA. DSA replied (on irc, there's no reply on https://rt.debian.org/Ticket/Display.html?id=6787 ) that they would prefer if those systems were not maintained by DSA but by the piuparts.d.o maintainers which is largely/only me. (And don't get me wrong, I ♥ DSA, this is just an example where I feel I cannot commit to do more permanent maintenance work on p.d.o...) I'd like piuparts.d.o to be extended to other architectures and whatnot, also to use piuparts for release.d.o even more, but, I also like this to be long term sustainable. This is like my 3rd or 4th attempt to improve this situation, I'm curious for the DebConf19 edittion ;) Disclaimer for readers in the future: of course this talk description is exaggerated, born out exhaustion and frustration. It's is a lame attempt to get more people involved. A non-lame attempt would focus more on the fun sides and the joys of being (partly) responsible that Debian lives up to the high quality standards it's known for. Hopefully $you will be proposing this talk for DebConf20 or 21! It's a bit more work than such a lame attempt but it's totally worth it! Carry the piuparts torch into the next decade!

Example server applications are a complete email server, a Wordpress blog (complete with ActivityPub support), and more. Using a read-only rootfs and containers, we provide an install, administration and update model that is similar to that of smart phone OSes. Breaking applications into subcontainers allows better isolation and security. For example, in an email server application, SMTP, spasassassin, clamav, IMAP and webmail can all be separate containers. Further, stateless containers like SMTP, spamassassin and clamav can be torn down and rebuilt for every incoming email, making compromising those services far less impactful to your privacy and security. Private services, like webmail and IMAP are only accessible via VPN, managed transparently for the user.

Unfortunately the computer that costs 35 USD in most countries often retails for 150 USD in Brazil due to shipping, insurance and customs duties. In an attempt to correct this, the Raspberry Pi Foundation was brought to Brazil and two years was spent in an attempt to license and manufacture RPis in Brazil. While ten systems were eventually produced, the request was denied. After that another design was located, and another path was followed. Three years later the "Labrador" was created and is now ready for large scale manufacture. More flexible than the Raspberry Pi Model 3, faster, with more RAM and more flexibility, the Labrador will run current releases of Debian. As the project progressed, it became a core component of the Brazilian Internet of Things (IoT) program along with a small sensor computer (the "Pulga", Portuguese for "Flea") and a soon-to-be developed small server/router system, the Bankar. The project also morphed from being "just create a less expensive "RPi" to stimulating design and manufacturing of high quality "Open" computer systems in Latin America. An NGO is being formed called "Caninos Loucos" ("Crazy Canines") and sophisticated plans for creating a completely Open Computing system with no binary blobs is in the works.

In this talk I shall present a Debian tool (`debos`) that helps creating customized Debian System images for different environments. `debos` has been created having embedded systems in mind. Images are customized via YAML description file, often called `recipe`. `debos` parses `debos recipes` to generate custom Debian images. `debos` is not only suitable for embedded images, but it can be used in other environments such creating VM images, cloud images, … `debos` is core component of several Debian derivatives CI loop.

In 4th November 2017 we received nine old servers and it was started a recovery project [1]. As result, five servers were recovered and it has been currently used for research and educational applications. This Cluster uses five old servers (named as Amanda, Carolina, Elisa, Gabriela, and Helena) running Debian 9 (Stretch). The Cluster is running at IFPR Telecommunications Laboratory (Labtelecom) in the internal network 192.168.1.0/24 [2]. Some characteristics of servers and network address are listed below: Amanda - 192.168.1.3/24 - Dell Power Edge 2850 - Intel(R) Xeon(TM) CPU 3.00GHz, 4G Carolina - 192.168.1.10/24 - Dell Power Edge 2850 - Intel(R) Xeon(TM) CPU 3.00GHz, 2G Elisa - 192.168.1.12/24 - IBM X-series 346 - Intel(R) Xeon(TM) CPU 3.20GHz, 256M Gabriela - 192.168.1.14/24 - HP Proliant DL380 - Intel(R) Pentium(R) III CPU family 1133MHz, 3G Helena - 192.168.1.16/24 - IBM E-server - Intel(R) Pentium(R) III CPU family 1133MHz, 2G Despite of legacy hardware, each server presents some operation and management functions, such as, DHCP Server, Local repository, Multimedia Server (DLNA), FTP Server, and Fail-over. This network has an average of 75 clients per day and an expansion up to 150 clients is expected in the next two years. The goal of this talk is to introduce how some minimalist configurations on Debian can easily provide network services in a low cost cluster. Some information and references about this cluster are described in Portuguese at: [1] https://sites.google.com/a/ifpr.edu.br/gustavothl/labtelecom/servidores-de-rede [2] https://sites.google.com/a/ifpr.edu.br/gustavothl/labtelecom/cluster Short talk (20 minutes) Gustavo Theodoro Laskoski True DebConf Video License (MIT-like) /talks/27-cluster-nfs/ https://debconf19.debconf.org/talks/27-cluster-nfs/ 2019-07-22T14:00:00-03:00 14:00 00:20 Miniauditório Other It is common to find local `sendmail(1)`-compatible Mail Transport Agent on workstations, usually configured as nullmailer (relay-only) to a remote submission agent. However finding a local IMAP server seems less common. Instead a typical desktop Mail User Agent implements the full mail stack, from storage to rendering/edition, via custom caching, threading, searching, and notification mechanisms. I will argue for local IMAP servers in order to reduce latency and enable offline mode with _thin clients_: such a client conforms to the UNIX philosophy as it takes care of rendering and nothing else, and relies on the underlying IMAP server for [searches](https://tools.ietf.org/html/rfc3501#section-6.4.4 "The IMAP SEARCH Command"), [sorting/threading](https://tools.ietf.org/html/rfc5256 "The IMAP SORT and THREAD Extensions"), [notification](https://tools.ietf.org/html/rfc5465 "The IMAP NOTIFY Extension") as well as storage (including caching). Such solution is fully compositional as it relies on documented protocols (namely [IMAP4rev1 and its extensions](https://tools.ietf.org/html/rfc3501 "IMAP4rev1")) for the gluing part. That leaves the problem of synchronization between multiple devices (and/or IMAP accounts), in arbitrary topologies. There again IMAP comes to the rescue with its [QRESYNC extension](https://tools.ietf.org/html/rfc7162 "The IMAP CONDSTORE and QRESYNC Extensions"), which enables stateful and efficient bi-directional synchronization between two IMAP4rev1 servers. I will briefly present such a synchronization program, [InterIMAP](https://tracker.debian.org/pkg/interimap "InterIMAP"), and show a few benchmark metrics to justify its presence in the ecosystem and compare with so-called “full” synchronization solutions.

From the beginning Chrome OS computers could run Chrome, and a few specially made applications, but since 2016 they also fully support Google Play, enabling users to access millions of Android apps. Chrome OS devices are readily available from many manufacturers. Since version 69 of Chrome OS, released in the fall of 2018, users can run a Debian GNU/Linux operating system inside a VM and container. This opens the option of running any Linux desktop app on a Chrome OS device, instantly making Chrome OS devices the most easily available Linux computer for a consumer to get.

It was initially developed inside Google but made available as Free Software in 2007 and has been included in Debian since Lenny. Since then, it has become a virtualization platform of choice for many companies and organizations around the world, among which the Debian Project itself. After a couple of years in hiatus, development is slowly resuming with the project being gradually handed over to the community. This talk aims to give a bit of background on Ganeti itself and describe the current state of affairs. It will highlight all present and future challenges, from community-driven development and project governance, to transitioning to present-day Haskell and Python 3 and supporting current hypervisor versions.

Through the exchange of experiences and practices with those who will attend the session, we'll talk about what make as feel "safe", the value of creating intersectional knowledge, ideas and realities with collaborative work in technology, and how to create this space together. Our audience is women and LBGTQI+ individuals, groups or collectives, to create a safe space to express freely, in a safe environment. Please, if you don't identify as part of the audience, we kindly ask you to participate in another activity. LGBTQI+ is an acronym that means Lesbians, Gays, Bi, Trans, Queer/Questioning, Intersex, and more.

That caveat disappears, however, if the FreedomBox has the Tor network as its only connection to the outside world. Entirely by chance, I found myself cut off from own public FreedomBox machine last year, but I soon discovered that Tor-only access has some distinct advantages. This talk will describe my personal experience installing and running a FreedomBox installation that is accessible only over Tor. Some of the difficulties found in combining FreedomBox and Tor are easily overcome, such as properly configuring multiple Tor hidden ".onion" services and securely distributing cryptographic key material. Other hurdles, however, point to weak points that users would be unwise to fiddle with, such as using long-term cookies with Tor Browser. The talk will describe the challenges and shortcomings encountered in depth — including Tor hidden-service management en masse, working with Let's Encrypt, key management, service persistence, remote monitoring, and mobile-device access. It will offer suggestions for expanding what packages FreedomBox offers, and will detail the configuration and preference settings required to use Tor Browser and Tor for Android with essential services. Whatever the obstacles, however, audience members will see that it is possible to not only combine the user freedom of FreedomBox with the anonymity of the Tor network, but to come away with a stronger system when the two work in concert.

Big tech companies have used this “walled garden” business model to concentrate market control, leaving consumers with fewer and fewer real options. In the United States, antitrust law hasn’t yet succeeded in stopping the concentration of power. But users want a new way to compute in the cloud: one that is free, open, trustworthy, and empowering. What should you do while the law catches up with technology? Free yourself from big tech using grassroots technology. Enter FreedomBox. FreedomBox is Debian’s home server system: it is a Debian pure blend designed to make it easy for anyone to host their own server on inexpensive, pocket-sized computer hardware. FreedomBox is designed around the principle that the exploitation of user data and attention should be technologically impossible. Its simple user interface empowers individuals to host their own Internet services without technical expertise, like an encrypted chat server that can replace Whatsapp, a VoIP server, a personal website, file sharing, a metasearch engine, and much more. In April 2019, sales of the first-ever commercial FreedomBox product were launched. The product, dubbed a “Pioneer Edition FreedomBox Home Server Kit,” is being sold by Olimex, a company which specializes in Open Source Hardware. In this talk, you will learn about big tech’s concentration of market control, how it effects users who rely on cloud services, and why antitrust law hasn’t succeeded in protecting consumers against this threat. Next, you will learn why Debian’s world-class software ecosystem should provide the alternative to big tech. Last, you will learn how FreedomBox uses Debian to empower people to leave big tech platforms. This session is targeted at a general audience who is interested in big tech and the cloud. No prior technical knowledge is required.

Still, they offer useful features that many people find valuable enough to make up for their perceived privacy loss, to everyone's detriment. What if we could get the useful features without sacrificing our privacy?

In addition to their fundamental weirdness (providing bits that are simultaneously a content element and executable code), fonts can be installed in multiple locations — system-wide and per-user, free-software and proprietary, from upstream repositories and from downloaded .zip files — and user applications are expected to gracefully handle all of the permutations within a single "Font" menu item. Font packages are a recurring stumbling block for smaller language communities, where operating-system support may lag behind and upstream designers may be wholly unacquainted with free software. Furthermore, the low-level privileges granted to font binaries poses practical and security challenges for newer application-packaging formats like Snap and Flatpak, as well as for transactional system-image operating system projects like OSTree and Ubuntu Core. This talk will outline the concerns of such app-packaging and OS-image projects, then present a possible solution in the form of a simple thought experiment: what if Debian stopped providing font packages altogether? In the hypothetical font-packageless world, individual users would install their own fonts on a per-user basis only. That change would trigger a number of ripple effects, from altering how system libraries like fontconfig match font names, to how GTK and Qt access fonts, to how end-user applications provide fonts. A user-only font stack would be simpler and have fewer security issues, and it could reduce the lag between an upstream font's release and its availability to Debian users. This talk will conclude with a look at the down sides of upending the font-packaging mindset, such as font management on the desktop, font versioning, global-language support, font synchronization, and font discovery. But it will, hopefully, ask attendees to reconsider how and why individual fonts are packaged for Debian and for other free-software distributions, and to explore possible alternatives in the years ahead.

Packaging MariaDB is a complex task and ensuring smooth upgrades and avoiding regressions requires a lot of work. However, with the introduction of Salsa, the Debian Gitlab service, and the continuous integration system it includes, every commit in MariaDB packaging is nowadays extensively tested and maintaining high quality is significantly easier. In this talk I explain how Salsa-CI works in general, how it is applied for MariaDB packaging in Debian, and how the testing system has evolved in the past year and how it has proven itself truly priceless.

However, sources are never enough to build a package: you also need an already-compiled Debian distribution to satisfy all the dependencies, which often create cycles and self-dependencies. This create a chicken-and-egg problem, with theoretical and practical implications. It has to do with security, auditability, architecture bootstrapping, reproducible builds and free software philosophy. Some projects are ongoing to fix this situation, both in Debian and outside of it. We would like to discuss the motivations, current state of the art, and future directions of bootstrappable builds. The long term goal is, one glorious day, to be able to compile the whole Debian given all of its sources and no more than a few kilobytes of binary code. Spoiler: we're not yet there.

During the BOF session, I'd be discussing a few topics like them, which would encourage more new contributors to join the team and help us in the maintenance of all the gems and applications. Moreover, something that worries me is the "retainment rate" of the new contributors. If this continues, then after few years down the line, the Ruby team would be in a little trouble.

Debian's ecosystem is so rich, reliable, and privacy-respecting that it is often used as the building material of other distributions. How can we promote this vision of technology in society more broadly? As individuals, we insist on integrating software freedom into our lives by using Debian. Many of us even try to offer software freedom to our friends and family. But what if we want to advocate for software freedom for our entire society or government? Changing laws, policies, and social norms is not easy, but it is an essential component of any social movement. Join this session to learn how Debian’s social purpose can be complemented by advocacy in law, policy, and society. You will hear from the CTO of India’s premiere digital liberties organization, SFLC.IN, which has worked on India’s IT policy at the national level, and a representative of the Software Freedom Law Center and the FreedomBox Foundation. This session welcomes people with any level of experience fighting for change. If you come to this session with lots of experience, then we hope that you’ll share it with others.

AppArmor is a Mandatory Access Control framework. When enabled, AppArmor confines programs according to a set of rules that specify what files a given program can access.

Sometimes governance "just happens" but more often than not, projects end up with some things that work and some that don't. Transparency, clear expectations and compassion go a long way towards helping you find people who support your vision but can still bring new ideas to the table when it comes time to talk implementation. Your project's governance should reflect your values and empower individuals to succeed within its structure. Specific topics that will be covered: * How to bring in people who share your vision * Why transparency matters * Sharing expectations early and often * Which legal decisions to sort out early Maintaining and scaling your project is easier when you've laid a good foundation. The wider community is mature enough that we can learn from what's already been done and set up new projects for success. This talk will cover some of the big red flags you'll want to avoid as well as some of the structural details that will help avoid issues later on.

In a most convenient form factor, and for a low sweet price. The Raspberry series helped define a whole segment in computing, and nowadays tens of similar computers with different characteristics are available. However, given the Raspberries require a non-free firmware blob to boot... There has been no support for running The Universal OS on it. Most Raspberries in the wild run Raspbian, a Debian derivative that deviates quite a bit more than what we would like. We have dirtied our hands with the non-free package ``raspi3-firmware'', have adopted some build infrastructure, and by the time this talk is presented, should have built fully functional images for all of the families in the Raspberryscape! I want to share in this talk the process and status, and help increase our work's visibility!

More boards are released to the wild every month! Sometimes they go feral, abandoned by their manufacturers and supported by volunteer communities. A few of the more recent ones even act suspiciously like laptops. The challenge is that they are all so similarly different. In order to boot Debian on a new, unique board, changes may be required in several packages, some needing coordination upstream, and some packaging changes may be specific to Debian. I'll touch on my workflows, communication channels, observation habits in the wild, and more to inspire your very own adventure!

OBS is a generic system to build and distribute packages from sources in an automatic, consistent and reproducible way. Andrew Lee will cover the benefits of using OBS, explain some of it features and workflow for all your packaging and releasing needs, like automatically build package from scratch on multiple target distros and architectures, and show you how to setup OBS infrastructure to build your own Debian based distro easily.

This is typically used by high-performance network interfaces, such as data centers and clusters. RDMA gives you high bandwidth and low latency. It typically requires support from the network interfaces, as well as potentially adapting the applications. This talk is a short HOWTO on using RDMA with Debian to make their high-performance network run faster. We will demonstrate how to test RDMA support without any specialized hardware (using soft-RoCE), and how to use it with existing applications (with libvma).Then finally, we will review the state of RDMA in buster and what is still missing, both in the kernel and user-space tools.

However, since OBS provides only rudimentary Subversion-like version control, this workflow has been proven to be inefficient, especially when it comes to merging updates from Debian or rebasing to a new release. Apertis is currently underway a migration which will result in all packages stored in Git only with OBS used for builds only. This transition is challenging since the way Debian packages have traditionally been built does not translate well to all-in-Git workflows. Lessons learnt as part of this transition are as beneficial for Apertis as they are for Debian itself and other derivatives. Since this work is currently in progress, but a major part of it is scheduled to be completed before DebConf, the description and the title of the talk are subject to change.

Later Jonathan called it as "geographical diversity", and I am using this idea for this BoF. So, let's talk how the Project can encourage people from southern hemisphere to contribute to Debian. Do we need more Debian events outside Europe and North America sponsored by Debian with DDs from there? Does Debian has budget to sponsor people to go to Europe and North America to join Debian events because most of DDs are there?

Nearly all have been already assigned, but if you are a DD, then you can still apply for one (by writing to zigo @ d.o, signed with your gpg key, using your Debian address), but please don't do it in Curitiba, it will be too late. Join me in a session where I'll teach how to use your Yubikey. You will learn: - How to generate subkeys and what they are for. - How to store the Auth, Sign and Encrypt subkeys in your yubikey. - How to ssh using a Yubikey (using the ssh key derived from your Auth subkey). - How to use KeepassXC as password store, with the password vault encrypted with the HMAC store on your Yubikey.

In this BoF we want to briefly explain how LTS is done, how you can support it, either finanically or by volunteer work and provide a venue for discussions how to improve it. The targetted audience for this talk is everyone, user, contributor, sysadmin, sponsor, you. Though of course due to the subjects being discussed this will be a quite technical discussion.

Debian shares the OSI's desire to encourage software freedom and Debian's Social Contract commits it to producing a system which is 100% free. Since 2012, the Debian Project has been part of the Open Source Initiative (OSI) as an affiliate member. This panel/talk will discuss the role of the OSI, some of the history of the OSI and Debian but also how the OSI's Open Source Definition is closely based on the Debian Free Software Guidelines, the document that defines the types of software licenses which the Debian Project accepts.

They are two of the most mature and dedicated organizations working in the free software movement. This is an annual opportunity to talk in person about how they can better work together and inspire each other. FSF members (and potential members) will meet to talk about the FSF’s work, the FSF's relationship with Debian, and progress of the movement as a whole: * A very brief update by the FSF’s executive director on highlights of the FSF’s work since the last DebConf * Feedback (positive and negative) from members, and a little brainstorming about what the FSF should and shouldn’t be doing * A review of the current relationship between the FSF and Debian * A discussion of areas for collaboration, focused on projects that could be completed or significantly advanced before the next DebConf Recognizing that we can't cover everything in 45 minutes, at the beginning, we'll choose some specific topics to focus on under this general umbrella. Past sessions at DebConf have led to concrete positive results like collaboration on the hardware database at https://h-node.org/. Let’s have another productive one!

Her widow, Monica Benicio, continued her fight for better treatment of the poor, the LGBT community and black Brazilians. Her murder has still not been solved and as the police investigation drifts, Monica is a plunged into a new crisis - the probable election of Jair Bolsonaro. On the eve of his inauguration, the film documents Monica’s involvement in the campaign opposing Bolsonaro and shoots of hope in the election of some local politicians from other parties, plus the aftermath of the election which suggests a terrifying future for LGBT rights and politicians who oppose the Government, and little hope for Marielle’s murder case being adequately solved.

We need to lead with a vision of how the world could be. A voluntary community, one where people participate by choice, does not have to replicate the power structures, gate-keeping or casual cruelty of the systems it seeks to replace. We could make free software the most empowering place to build software. Free software tools could enable new ways of crafting user experiences that proprietary software providers seem unwilling to offer. Free software could tranform the relationship between users and developers, so that users feel like partners instead of sales metrics. Free software communities should be seeking to outdo proprietary software's methods and social norms in every possible way. This talk will focus on: * The people we're building free software **for** * The people we're building free software **with** * The people who aren't here **yet** We've made a great start by empowering many technical and semi-technical users, but we can't stop there. (What kind of utopia only has coders in it?) Let's build a kinder and more practical free software movement to empower all kinds of people!

I'll share how we use it to dynamically generate preseed files that can be used along with the Debian-installer. Shoelaces serves iPXE boot scripts, cloud-init configuration, and any other configuration files over HTTP to servers booting over iPXE. It also does a few other things to make it easier to manage your server deployments, such as: * using templates to avoid repetition * automatic install-script selection by using IP, network or PTR of the booting server. * Shoelaces is lightweight. Given that it was coded in Go, it's distributed as a single binary and does not have heavy dependencies. It also does not use any database, making it's installation and usage a bliss. * provides a simple but nice UI to show the current configuration, and history of servers that booted. The target audience for this talk is administrators that have to install baremetal servers on a regular basis and are looking forward to automate this task.

For better or worse this indifference doesn't usually last long, as any project involving more than one person soon discovers that it's not just about cranking out code, but about dealing with conflict, motivating volunteers, and balancing differing goals and priorities. This session will be for sharing best practices, lessons learned, and asking questions. Whether you are the Debian project leader, or coordinating with one other developer on a project with 3 users, this BoF welcomes your ideas and your questions.

So, what's the big deal? Go download DJ software and get with the mix. There's even DJ software in Debian. I'm blind and for the work I'd like to do all the software is visual. So I decided to write my own. This is a case study about how Debian and the free software we curate made it possible for me as someone who sees the world differently to find art and achieve a dream. It's more about how free software opens opportunities to view the world differently than the technical challenges I faced, although I'll throw in some code for good measure. It's a story of opportunities realized but also challenges relating to people who think differently. It's a story of art and the power of understanding how the world works.

Liberty is again being threatened and computer software pervades every single act of our daily routines. Even our sense of self is at stake when e-book readers and TVs can gather more information about our feelings, emotions and reactions than ourselves. Who are we anyhow? In a somewhat marginal, far-from-the-mainstream trend, programmers and enthusiasts work on a different direction, one that is closer to what the roots of this digital revolution were about. Thanks to these warriors we are now able to run a 100% free computer system on our homes, one that does not subjugate us, a freedom respecting, collectively developed and transparent environment with which we can do our computing our way, with no big brother to pull our strings and rob us from our will. In this talk / concert we will present how far FOSS has come as general purpose workbench and discuss about how a musician, artist and engineer struggled for two decades in the search of a platform to perform his craft that doesn't compromise his freedom and ethics. Even though we still face many challenges ahead (fragmentation and lack of hardware support to name a couple), like an empty canvas to a painter, a Debian-powered computer in 2019 allows a sound designer to create textures, rhythms and ambiences, to bend time and space, to manipulate reality. This talk/performance is targeted to users and developers interested in helping to pave the way for GNU/Linux as a creators' platform. Art is freedom, music is freedom, our hearing capabilities and sensibility to sound is what kept us alive as a species in our caves at night, hundreds of thousands of years ago, and it is time to fight again.

I'd like to show how these are structured so that people can perform these tasks: - add fixes on top (mostly for SRUs [Stable Release Update]s) - contribute to the release in development - how to quickly check what is the Ubuntu Delta wrt Debian - how to perform merges from Debian, i.e., apply the Ubuntu delta on top of the Debian package BoF (45 minutes) Andreas Hasenack True DebConf Video License (MIT-like) /talks/143-using-git-for-ubuntu-packaging/ https://debconf19.debconf.org/talks/143-using-git-for-ubuntu-packaging/ 2019-07-26T14:30:00-03:00 14:30 00:45 Miniauditório Packaging, policy, and Debian infrastructure Currently Salsa admin and the Salsa-CI team are two separate groups with no overlap. In this session we could discuss how these teams could collaborate in the future, and in general check how well aligned the interests and goals of these teams are. Salsa as git hosting and Salsa-CI as quality control is a great combo that helps a lot of Debian Developers to save time on change managements / regression testing and thus empowers them to do more truly productive work to help Debian.

How far have we come? Is Debian (and Free Software) gender diverse enough? What are we doing to improve diversity? Are these steps effective/sufficient? If not, where are we going wrong? What more can we do? These are some of the questions which we will explore to find answers/solutions/actions. This will be more of a discussion, and not a talk.

Selecting appropriate distro and tools is necessary for efficient product development. Especially in the industrial world, 10+ years maintenance is required, including security fixes, reproducible builds, and continuous system updates. Debian has been applied to industrial products because of its affinity with the demands in such developments. Kazuhiro will introduce several approaches for embedded product development, which are based on Debian sources, binaries, and tools. He also shows the basic usage and preferred use cases of each approach, including the relations between important features in Debian.

Buy this ethically made product; don't buy that one made by a company that funds terrible things. In free software, we encourage people to boycott (for example) Microsoft, and to instead support companies who sell machines with GNU/Linux. It's an intuitive idea that, as individuals wanting to make the world better, we should use our willingness to spend or not spend money to reward those who do right and punish those who do wrong. Throughout history, this has sometimes been effective. But how effective? Can it be dangerous? There is a danger of *reducing* activism and social change strategy to these decisions. We see this in the free software movement, when some activist campaigns aimed at persuading people to stop using proprietary software are met with responses like, "If you don't like Apple products, just don't buy them. Help make free products that are better than theirs. Why campaign against them?" or "How can you criticize proprietary software but still drive a car that has it?" As an advocate, have you ever heard these responses, or felt like a hypocrite, or stumbled trying to explain to others why the situation is more complicated than "just don't buy it"? How do we form a holistic movement strategy for advancing user freedom that takes consumer activism as far as possible, without overprioritizing it? How does or doesn't Debian fit into the picture? I hope those interested in effectively fighting for user freedom will join me as I share thoughts formed from 16 years of experience working on the Free Software Foundation's advocacy efforts, against the backdrop of some highlights from the history of other social movements.

A single computer is shared by an indefinite number of users. Lots of security concerns arise. In Asia and elsewhere multiple non-latin languages have to be supported. We decided to create a custom lightweight distribution, Meilix and a generator web app that allows you to preconfigure an ISO with the wallpaper and desktop settings in place. Here in India I study as an undergraduate electrical engineering student but I was thrilled to work with a grant of FOSSASIA on the Meilix (“Mei” means roughly “nice”) project for several months. In this talk, we will get into the challenge to build our own customized Kiosk. You will also understand the workflow of the project and the best use of Travis CI and Github infrastructure. We use Flask framework to design a basic webapp named Meilix-Generator for the user to go there and provide their configuration and build their distro. We deploy the webapp on Heroku. We took the most common approach to a project which gives a GUI to customize our own Linux Distro with LXQT as a desktop environment, which is implemented first time ever. I will explain what steps we take to make internet access more inclusive and exciting for everyone and what steps we undertake to add conversational interface features.

We need to have an open discussion about the political message that this project decision sends, and how it affects the people within our community who support the BDS (Boycott, Disinvestment, Sanctions) movement against the policies of the Israeli Government, all the while reiterating our support to the individual members of the local organizing team, who are our peers in Debian. A campaign has been brewing for a few weeks, calling on the DebConf Committee and the Debian Community to rescind the decision of holding the project's yearly conference in Israel. We hold this session to have an open, small scale conversation, hopefully with members from the DebConf 2020 team, members of the DebConf Committee, supporters of the boycott movement, and other stakeholders in the Debian community, to try to come up with ideas how to move forward.
