The Internet has been under a spell over the M1 system-on-chip. Is Apple's GPU architecture magically faster than the rest of the industry? Or is it all smoke and mirrors? Only a reverse-engineering witch can divine that truth. Grab your cape, because we're about to spill the chip's secrets, solve mysteries we were never supposed to know about, and gain a Mesa driver along the way. about this event: https://c3voc.de

Lima is an open source graphics driver which supports Mali Utgard (Mali-4xx) embedded GPUs from ARM. It’s a reverse-engineered, community-developed driver. At XDC 2019 there was a presentation about Lima, which happened not long after its initial inclusion in upstream. At that time, it was still missing some important features to be a complete driver. Most of those have been addressed since then and the situation now is notably more stable. This talk aims to provide a status update on Lima, a review of the more relevant recent work on it, and some possible paths going forward. about this event: https://c3voc.de

BornHack 2021 is almost over at this point. We would like to say farewell for now and see you again at the next event in 2022. We will walk over what we believe has worked and what we believe should change the next event. This is an excellent opportunity to submit ideas for BornHack 2022 while the memories are still fresh. about this event: https://bornhack.dk/bornhack-2021/program/goodbye-world/

Come and meet the network team who will talk about the design and operation of the network at BornHack. about this event: https://bornhack.dk/bornhack-2021/program/state-of-the-network/

I have for a few decades worked in networking and security, and everything seems to have grown. I will try to lay out a path for people who wants to get into networking and security, with some references to pentesting, software security, and related areas. Where to start and which skills you should start learning. I will use my existing courses as a guide. These are taught as part of the of the Diploma in IT Security at KEA Kompetence https://kompetence.kea.dk/uddannelser/it/diplom-i-it-sikkerhed Note: I will reference book resources, but if you are on a tight budget lots of other resources may be used instead. Related links: https://zencurity.gitbook.io/kea-it-sikkerhed/ lecture plans and book references https://github.com/kramse/security-courses all my training and educational materials, including exercises booklets with small exercises that you can do with virtual machines like Debian and Kali Linux using lots of open source tools. about this event: https://bornhack.dk/bornhack-2021/program/getting-started-in-network-and-security/

In this talk Holger Levsen will give an update on Reproducible Builds of Debian and beyond. He’ll briefly sum up the status in Buster, then present developments in and for Bullseye and give an outlook on Bookworm, what’s planned, being built and wished for! Bullseye will be the third Debian release since work on Reproducible Builds of Debian has really started: we started with the beginning of the Stretch cycle, then continued for Buster and we are still not done with our work on Bullseye, though hopefully at the time of the talk we will be. And then of course we will continue for Bookworm and beyond! The last paragraph might leave you wondering, what exactly has changed, where we are, why we still are not “there” yet and what our immediate plans are. So come and see this talk! about this event: https://bornhack.dk/bornhack-2021/program/reproducible-buster-bullseye-bookworm-where-we-come-from-and-where-we-are-going/

Ever since trying the Orbital Ion Cannon from C&C red alert, I've had a dream of sending a laser into space (on purpose) - while this certainly would be an interesting backstory, the truth is somewhat more boring... When making cubesats and micro satellites, the data downlink is one of the more difficult and costly things. By moving from traditional radio-based downlinks to a optical system, data can be transferred much faster and hence more science can be conducted on the satellite. This presentation will cover the current state of the project as well as some of the challenges that has been encountered. about this event: https://bornhack.dk/bornhack-2021/program/lasers-in-space/

Ever wanted to build and control a 3-5 meter high flame ? Even higher ? Than this is the talk for you! Want to know how to build it safely, not blow up yourself in the process and enjoy making your own flame effects to be used on hackercamps/steampunk events/festivals ? It (re)-uses readily available materials and improvements can be made to suit your own requirements. about this event: https://bornhack.dk/bornhack-2021/program/building-your-own-flame-effect/

Mike is currently working on a book who aims to uncover the story behind a rare Danish built and designed series of computers called the "ICL Comet", and yes ... you might wonder, "ICL is not a danish company" - and you would be right, the machine was sold by ICL, but build, designed and produced by different small Danish Companies. I have spent three years collecting sources for this books, and the project just exploded in scale and that in itself has become a great story, which I am going to tell you about. If you like old computers you most definitely want to attend to my talk! about this event: https://bornhack.dk/bornhack-2021/program/the-danish-comet-the-first-danish-microcomputer/

The Update Computer Club was founded in 1983 as a student club at Uppsala University. It aims at connecting people who are interested in all kinds of computer related topics such as hardware, software, running modern or historic computers, computer architechtures, operating systems, or programming. Over the years the club has collected a large amount of historic hardware that documents the history of computing in Sweden. The collection includes a DECSYSTEM-2060, a Cray Y-MP EL, a Symbolics 3650, and a (mostly) working PDP-12. With the upcoming move of the Uppsala University IT department to a new building Update is at risk of losing its rooms, and therefore its collection. We need your help to preserve this bit of computing history! about this event: https://bornhack.dk/bornhack-2021/program/save-the-historic-computer-collection-of-the-update-computer-club/

I will quickly touch on what NetBox is and why we have been using it as inventory for Ansible on our on-prem systems at QuickPay. Then show/explain some of the issues that we've had to work around. about this event: https://bornhack.dk/bornhack-2021/program/netbox-as-ansible-inventory/

Cactus Comments is a federated comment system for the open web built on Matrix. It is GPLv3 licensed, written in Elm, and we host a public backend that's free (as in beer) to use.

In this talk, I introduce the digital ride-hailing apps in Indonesia, Gojek and Grab, and show how they evolved from transport to a broader platform of financial services, including the private issue of ‘e-money’ for their integrated payment systems GoPay and OVO. I examine how they advocate for the expansion of cashless so-called peer-to-peer (P2P) payment systems, and use algorithmic labour management to mobilise their driver fleets to facilitate the use of digital money by customers of the app. I argue that promoting the notion of peerhood by the companies both obfuscates how their apps configure users to participate in new hierarchical exchange relationships, as well as minimizes the companies’ role as intermediary, and how the transactional constellation of P2P camouflages the financial interests that these companies have in generating platform activity. Through this work, I show that the exchange of digital money through these ride-hailing apps constitutes far more than the financial transaction and contains much more than can be summarized in an elegant acronym. about this event: https://bornhack.dk/bornhack-2021/program/peerhood-and-the-privatisation-of-money/

Traditionally, individual servers are provisioned with Foreman/ Katello and they can be configured with Ansible, Puppet and Salt which is a host centric deployment. However, a modern application typically consists of multiple services running on different servers but connected to each other. The new plugin Foreman_acd defines application centric deployment and describes an approach to provision and configure hosts to run an application which requires predefined set of services. This presentation compares host centric and application centric deployment, talks about how you can seamlessly deploy the application with only few clicks, a user friendly approach to utilize your ansible playbooks directly from Github or Gitlab, import/export your application services and configurations rather than creating it in systems from scratch, and how you can vertically and/or horizontally scale up your application fast. The plugin Foreman_acd is a recently released open source Foreman plugin to deploy your applications containing multiple services and interconnected servers with only few clicks. about this event: https://programm.froscon.de/2021/events/2691.html

Eine Groupware mit integrierten Online Office verlegt das Office in den Browser. Nicht nur für das Corona-Home-Office, Orts- und Clientunabhängig. In EGroupware kann Collabora Online als klassisches Online Office und/oder zum Erstellen von Dokumenten genutzt werden. So können Formulare, Protokolle, Zeitnachweise, etc. direkt aus EGroupware erzeugt, geteilt und versendet werden. Der integrierte Dateimanager/Fileserver (mit Filesharing) und Collabora Online (COOL) ermöglichen das gemeinsame und ortsunabhängige Bearbeiten von Dokumenten. Externe können ebenfalls Dokumente bearbeiten, Verzeichnisse können per SMB, WebDAV oder FTP eingebunden werden und per WebDAV kann von Clients/Dateimanager zugegriffen/geöffnet werden. EGroupware stellt fast alle Felder (auch die benutzerdefinierten) als Variablen zur Verfügung. Diese Felder werden, eingefügt in ein Dokument/Tabelle/Präsentation/Zeichnung (oder E-Mail), bei Aufruf gefüllt. So ist in vielen Fällen bereits ein digitaler Workflow ohne viel Aufwand oder spezielle (Branchen-)Software möglich. Inhalt des Vortrags: * Überblick über EGroupware * Leistungsumfang – Das „Mehr“ an Groupware * Community Edition vs. Enterprise Edition * Neues in der Version 21.1 * Überblick über Collabora Online * COOL vs. CODE * Community * Neues in den letzten Versionen/Roadmap * Integration COOL in EGroupware * Installation/Integration * COOL im Dateimanager/Filesharing * Dokumentenerzeugung * Beispiele aus der Praxis (Jeweilige Beispiele unter Vorbehalt) * Digitaler Rechtsanwalt * Schulverwaltung * Veranstaltungsorganisation * Fragen/Antworten Die Vortragsfolien werden in der auf die FrOSCon folgende Woche hier veröffentlicht. Fragen/Antworten werden noch einmal schriftlich und mit Screenshots ausführlicher betrachtet. Vorkenntnisse sind nicht erforderlich. Eine detaillierte Übersicht über EGroupware bieten zwei Vorträge (Anwender-Sicht und Admin-Sicht) der Linux Tage 2020: https://help.egroupware.org/t/de-tux-tage-2020-vortrage-zu-egroupware-videos-und-vortragsfolien-verfugbar/75555 Ein längerer Vortrag von den Grazer Linux Tagen zeigt die Neuerungen der EGroupware Version 21.1 auf: https://help.egroupware.org/t/de-vortragsvideo-und-folien-vortrag-grazer-linux-tage-2021-neues-in-egroupware-21-1/75877 Ein älterer Vortrag von der FrOSCon 2019 zu LibreOffice Online steht ebenfalls zur Verfügung: https://help.egroupware.org/t/de-uk-folien-vortrag-slides-lecture-froscon-2019/73767 Weitere Links: siehe rechts about this event: https://programm.froscon.de/2021/events/2661.html

Nachdem ich am Anfang vom ersten Lockdown im Frühjahr 2020 zwei Wochen straight vor lauter Sorgen Kopfschmerzen hatte und fertig war, hab ich mich mit der Situation irgendwie arrangiert. Ich hab zwar etwas vergessen, wie man tanzt oder in die Kneipe geht und Freund*innen umarmt, aber dafür paar andere Dinge gemacht. Zwischendurch bin ich auch auf den Begriff "Scanner"-Persönlichkeit gestoßen, der meinen Drang dazu, haufenweise neue Projekte zu starten (und gefühlt nichts zu Ende zu bringen) in eine neue Perspektive gerückt hat. In diesem Talk gebe ich einen Überblick darüber, was eine "Scanner"-Person ist, und stelle einige Tools vor, die euch zur Verfügung stehen, falls ihr euch in dieser Beschreibung auch wiedererkennt. Und außerdem erzähl ich euch von all den Projekten (mit und ohne Holz), die ich in der Pandemie gestartet, weitergemacht oder gar abgeschlossen hab. Hast du auch nie eine Antwort auf die Frage "Und was willst du werden, wenn du groß bist?" gewusst? Findest du es schwer, dir vorzustellen, dich auf eine einzige Sache zu konzentrieren? Startest du immer voller Begeisterung viele neue Projekte, die auf dem ersten Blick thematisch nichts mit einander zu tun haben? Und fühlst du dich dann gestresst und unglücklich, weil du gefühlt nichts davon zu Ende gebracht hast? Oder trifft das alles auf dich vielleicht nicht zu, dafür aber auf deinen besten Freund oder deine Schwester? Ich war schon lange auf der Suche nach dem einen Ding, das ich mit meinem Leben anfangen sollte. Das so viel Spaß macht, dass man da komplett aufgehen kann und eben dabei bleibt anstatt zum Nächsten zu springen. Gefunden hab ich es nicht, aber nachdem ich letzten Sommer auf den Begriff "Scanner" gestoßen habe, fühle ich mich damit wohler. In diesem Talk stelle ich das Konzept von "Scanner"-Persönlichkeit vor, sowie eine Auswahl an Tools und Ressourcen, die Scannern helfen könnten, ihren verschiedenen Interessen stressfreier nachzugehen. about this event: https://programm.froscon.de/2021/events/2688.html

Inspired by Niels Serups inspirational talk about unspectacular personal failures, here is one about my first excursion into the relm of dependently typed programming. When learning about dependent types, one is often presented with cannonical examples such as a list that is parameterized with its lenght. However, dependent types turn out to be quite useful for inferring properties about terms. An exapmle of such a property is coarsest grid needed to notate a rhythmic pattern in a drum machine, and in this talk I will explain what that means, and go over an Agda-embeded implementation of a programming language that inferres that. With some probability, the talk will inspire some of you to start hacking on a project of your own, using Dependent Types in new and cool ways. about this event: https://bornhack.dk/bornhack-2021/program/tsh-a-dependently-timed-drum-machine-language/

Matrix ist ein offenes Chatnetzwerk für sichere, dezentrale Kommunikation. Keine Lust mehrere Chat-Clients zu installieren um alle Freunde zu erreichen?
