But what comes after VR glasses and haptic feedback? This is a hacker-friendly introduction to the biological, technical and ethical challenges of high-bandwidth direct brain communication.\ncw: blood, pictures of brains\n\nLike computers, our brain uses electrical signals for computation. By building devices capable of recording and decoding these patterns of neural activity, we can read information from the brain. By encoding and stimulating neurons using electric fields, we can establish bidirectional brain-machine communication.\n\nThis talk highlights why increasing the bandwidth of our interaction with computers is a key technology in the Information Age. We talk about where we are today, comparing non-invasive (EEG,  EOG, MRI) and partially invasive (ECoG and endovascular) to invasive (microelectrode array) approaches. After this talk, you'll have a basic understanding of current engineering challenges, and why your next open-source project should be a brain-machine interface.","original_language":"eng","persons":["Lucy Fauth"],"tags":["gpn20","94","2022","Science","gulaschprogrammiernacht","gpn","entropia"],"view_count":605,"promoted":false,"date":"2022-05-21T17:45:00.000+02:00","release_date":"2022-05-22T00:00:00.000+02:00","updated_at":"2025-06-30T21:00:03.326+02:00","length":3587,"duration":3587,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/94-197b9a36-c4c2-5471-a67b-5a2a104c24f5.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/94-197b9a36-c4c2-5471-a67b-5a2a104c24f5_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/94-197b9a36-c4c2-5471-a67b-5a2a104c24f5.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/94-197b9a36-c4c2-5471-a67b-5a2a104c24f5.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-94-after-the-metaverse-an-introduction-to-brain-machine-interfaces","url":"https://api.media.ccc.de/public/events/197b9a36-c4c2-5471-a67b-5a2a104c24f5","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"3bf90d0f-8c50-5b9b-b919-d6cbf0c5b4c8","title":"RP2040 PIO Emulator as DevTool","subtitle":null,"slug":"gpn20-51-rp2040-pio-emulator-as-devtool","link":"https://cfp.gulas.ch/gpn20/talk/7BKJ7J/","description":"Developing PIO programs for the Raspberry Pico RP2040 chip is really hard, since -- in contrast to the ARM cores -- access to the PIO's inner state is very limited, and debugging output and tracing almost impossible.\nTherefore, in early 2021, I implemented an emulator for the RP2040 PIO, and a set of tools (for the command line as well as GUI based) and a very simple scripting language for program control and debugging output.

This talk will try to convey the what, why and how of the hunt for the unknowns of the Universal machinery to the uninitiated. It will try to give an overview of the basics of the (little?) we know and what is still out there and then give a guided tour through this truly magnificent effort focusing on the CMS (Compact Muon Solenoid) detector. It will finish by telling a few stories from the front line of trying to build one of the most ambitious (Sub)Detectors in the history of the LHC for the High luminosity upgrade of the CMS detector.\n\nThe abstract may sound daunting, but rest assured, that is the case for everyone at some point. In this talk I’d like to share the principles and functioning of one of the most complex machines I know of in a way that makes sense. I have had the privilege of working at CERN on the HGCAL subdetector of CMS and was able to gather first hand experience of the many different challenges of building this one of a kind machine that at the end of the day is nothing more than a terribly overengineered photo camera. I hope that I can share my motivation and passion with you and get you stoked for all of what is still to come.","original_language":"deu","persons":["Alexander (Nabla) Becker"],"tags":["gpn20","86","2022","Science","gulaschprogrammiernacht","gpn","entropia"],"view_count":105,"promoted":false,"date":"2022-05-21T16:30:00.000+02:00","release_date":"2022-05-21T00:00:00.000+02:00","updated_at":"2025-06-17T22:00:05.550+02:00","length":3561,"duration":3561,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/86-1bb40b7c-ff94-5b88-a611-551fd11b735a.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/86-1bb40b7c-ff94-5b88-a611-551fd11b735a_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/86-1bb40b7c-ff94-5b88-a611-551fd11b735a.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/86-1bb40b7c-ff94-5b88-a611-551fd11b735a.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-86-the-lch-cms-and-the-future-of-high-energy-physics-and-why-we-would-like-your-help-","url":"https://api.media.ccc.de/public/events/1bb40b7c-ff94-5b88-a611-551fd11b735a","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"83ad96fd-81b7-538e-aa7e-c8980b6b909a","title":"Lightning Talks - Day 2","subtitle":null,"slug":"gpn20-96-lightning-talks-day-2","link":"https://cfp.gulas.ch/gpn20/talk/QCRWZH/","description":"A 60min lightning talk session","original_language":"deu","persons":[],"tags":["gpn20","96","2022","Entropia / CCC","gulaschprogrammiernacht","gpn","entropia"],"view_count":186,"promoted":false,"date":"2022-05-20T20:00:00.000+02:00","release_date":"2022-05-20T00:00:00.000+02:00","updated_at":"2025-03-17T20:15:04.988+01:00","length":3441,"duration":3441,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/96-83ad96fd-81b7-538e-aa7e-c8980b6b909a.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/96-83ad96fd-81b7-538e-aa7e-c8980b6b909a_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/96-83ad96fd-81b7-538e-aa7e-c8980b6b909a.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/96-83ad96fd-81b7-538e-aa7e-c8980b6b909a.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-96-lightning-talks-day-2","url":"https://api.media.ccc.de/public/events/83ad96fd-81b7-538e-aa7e-c8980b6b909a","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"e0023d6e-51aa-5890-9db0-28b112fe9c97","title":"The Rube Goldberg Database - Introduction to Postgres functions and triggers","subtitle":null,"slug":"gpn20-69-the-rube-goldberg-database-introduction-to-postgres-functions-and-triggers","link":"https://cfp.gulas.ch/gpn20/talk/PHPHGW/","description":"Brief introduction to some neat and underappreciated Postgres features that let you do stuff within the database that you probably hadn't imagined was even possible.\n\nSounds complicated?

Wehe aber, ihr installiert und nützt dieses System nicht! Wer sich verweigert, bekommt weniger Honorar für seine Arbeit!\n\nWo sich dieser Wahnsinn abspielt? Im deutschen Gesundheitswesen. Der Anschluss an die Telematikinfrastruktur (TI) zur Vernetzung von Praxen, Kliniken und anderen Akteuren ist seit 2018 Pflicht. Darüber läuft nun auch die elektronische Patientenakte (ePA), die die Gesetzlichen Krankenkassen seit 1.1.2021 anbieten müssen. \n\nDie Nachfrage der Patienten hält sich bisher in Grenzen, in meiner Praxis gleich null. Die zentrale Speicherung sensibler Daten in Clouds verunsichert viele Menschen. Sie wollen sich oft auch mit nötiger Technik und PINs nicht beschäftigen - verständlich. Und das E-Rezept, kurz vor Zwangseinführung zum 1.1.2022 doch noch verschoben, können viele meiner Patienten gar nicht empfangen – über die Hälfte aller 65-Jährigen nützt kein Smartphone.\n\nPapier, Fax und Rezept mögen oldfashioned und rückständig sein. Aber sie sind einfach, schnell zu bedienen und relativ billig. \nTI und ePA aber sind komplex (Entropie!), teuer, bringen wenig Mehrwert und bremsen dafür den workflow in den Praxen. Burnout durch digitalisierungsbedingte Mehrarbeit? In den USA heute schon Realität. \n\nGesünder macht die ePA leider auch nicht. Patienten brauchen eher analoge Beratung und Beziehung. Jetzt aber werden Ärzte und Patienten zu Datenlieferanten für die Industrie gemacht – die schon großes Interesse an den Daten signalisiert hat. Das deutsche Gesundheitswesen bisher ist gut, aber sowieso schon teuer. Der nötige Aufwand für entsprechenden Output (Entropie!) wird durch TI und ePA nur verstärkt. Dabei gäbe es andere dringende Notwendigkeiten im Gesundheitswesen.\n\nVorschläge für eine sichere, dezentrale e-Health-Struktur wurden bereits gemacht, bisher aber ignoriert. Manches wäre ja sinnvoll, etwa schnelle Befundübermittlung auf sicheren Kanälen direkt an Patienten und Kollegen – ohne Speicherung auf Servern. Es müsste einfach bedienbar sein, Mehrwert haben – und freiwillig sein!","original_language":"deu","persons":["Dr. med.

Thus, it only contains the code necessary to fulfill the single purpose it was created for. Most unikernels run on top of a hypervisor. Due to the minimalist approach, unikernels are very resource efficient, which makes them attractive for cloud and high performance computing.\nMultiple unikernels claim to be more secure than a traditional operating system due to their massively reduced attack surface. But is this really true? Or are they too minimalist and leave out important security features? What are the implications of a single address space? Is every security problem solved when rewriting the unikernel in Rust?\n\nWhile there are multiple papers analyzing unikernels from a performance perspective, there are only few analyzing them from a security perspective and none of them analyzes a unikernel written in a memory safe language from scratch.\nThus, I decided to analyze and discuss unikernel security in my master thesis. The core part is an extensive analysis of the RustyHermit unikernel, a unikernel written in Rust and developed as a research project at RWTH Aachen University. In addition, I analyzed multiple unikernels for the most basic security features present in traditional operating systems, e.g.  ASLR, W^X and stack canaries.","original_language":"eng","persons":["harryr"],"tags":["gpn20","4","2022","Security","gulaschprogrammiernacht","gpn","entropia"],"view_count":194,"promoted":false,"date":"2022-05-21T16:30:00.000+02:00","release_date":"2022-05-21T00:00:00.000+02:00","updated_at":"2025-05-30T03:15:03.228+02:00","length":3317,"duration":3317,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/4-94e75c09-fbb1-584c-86c5-3f2d17853626.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/4-94e75c09-fbb1-584c-86c5-3f2d17853626_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/4-94e75c09-fbb1-584c-86c5-3f2d17853626.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/4-94e75c09-fbb1-584c-86c5-3f2d17853626.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-4-unikernel-security-analysis","url":"https://api.media.ccc.de/public/events/94e75c09-fbb1-584c-86c5-3f2d17853626","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"829e3689-ab34-5946-90a1-66f561036d7c","title":"Radiosonden - STM32 Devboards, die (buchstäblich) vom Himmel fallen","subtitle":null,"slug":"gpn20-52-radiosonden-stm32-devboards-die-buchstblich-vom-himmel-fallen","link":"https://cfp.gulas.ch/gpn20/talk/UE7LWK/","description":"Radiosonden sind die Messgeräte, die an Wetterballons hängend tagtäglich Daten für die Wettervorhersage generieren.

Do you write standards and test fixtures that need to be used in lots of languages, so you need a format everyone can agree on?  And lastly, do you use Markdown?\n\nTestmark is a simple convention for annotating code blocks in markdown so they can be loaded into your program as data.  It's great for test fixtures and executable examples.  Libraries let you treat it as a pseudofilesystem: you can put as many data hunks as you want in one file, and also update them programmatically.  The testmark parsers also carefully leave the rest of your markdown _alone_, meaning you can intersperse whatever prose and styling with your code blocks you want.\n\nIn this talk, we'll show the testmark syntax, the testmark libraries (yes, in multiple languages), and examples of testmark in the wild and the impact it had on projects that adopted it.  Also, there are extensions to testmark dedicated to blackbox testing of executables; come see those in action too!","original_language":"eng","persons":["Eric

Linux Audit Subsystem (\"auditd\") ist geeignet, um feingranulare Events aufzuzeichnen, aber das Format taugt nicht zur Weiterverarbeitung. Ich gehe auf die Probleme des Formats ein, zeige, wie man dieses Problem mit vertretbarem CPU-Overhead gelöst bekommt und was man bei der Gelegenheit noch tun kann, um dem Analysten, der in sein SIEM starrt, die Arbeit zu erleichtern.\n\nNetzwerktraffic im Klartext ist eher zu einer Seltenheit geworden, das ist natürlich gut. Die Kehrseite der Medallie ist, dass für die Erkennung von Angriffen in Unternehmens- und anderen Netzwerken netzwerkbasierte Indikatoren an Bedeutung verloren haben und hostbasierte Indikatoren heute eine größere Rolle spielen. Wir wollen nicht nur schauen sondern sehen, sind aber nicht bereit, dafür auf jedem System eine Horde von Blockchain-AI-EDR-Agenten zu installieren. Also müssen wir etwas fürs Logging tun, und zwar mehr als die üblichen Authentifizierungs- und Autorisierungs-Events.\n\nFür Windows gibt es hierfür das bei SysInternals entwickelte \"Sysmon\", es ist closed source aber kostenlos und kein von Microsoft unterstütztes Produkt. Auf Linux-Systemen haben wir dafür seit 15 Jahren mit dem Audit-Subsystem eine gut funktionierende aber leider schlecht verständliche Quelle der Wahrheit: Das textbasierte Logformat ist für typische SIEM-Systeme zu irregulär und schlecht zu parsen. Unterschiedliche Aspekte eines Events sind auf mehrere Zeilen verteilt; nun sind die üblichen SIEM-Systeme im Kern eher Suchmaschinen und nicht besonders gut darin, JOIN-Operationen auszuführen. Leider ist das alles kaum noch zu ändern, weil die Rohdaten direkt im Kernel-Code erzeugt werden und als Teil einer Kompatibilitätszusage verstanden werden.\n\nBestehende Lösungsansätze ersetzen ohne Not das bestehende auditd-Userland (go-audit, auditbeat),  bringen große Performanceprobleme mit sich (auditbeat, osquery, Skriptsprachen) oder setzen mit eBPF ohne Not auf \"shiny new tech\", ohne daraus einen Erkenntnis- oder Performancegewinn zu ziehen (Sysmon for Linux).\n\nUm die bestehenden Schmerzen zu lindern, ist [LAUREL](https://github.com/threathunters-io/laurel) als _auditd_-Plugin entstanden, das die Events in Echtzeit aufbereitet und in ein SIEM- und Analysten-verträgliches JSONlines-Format kodiert. Dabei kommt LAUREL auch bei hoher Event-Rate mit vertretbarem CPU-Overhead aus.\n\nWar es ursprünglich als reines Umkodierungstool gedacht, fallen nach der ersten produktiven Bewährungsprobe natürlich weitere Use-Cases auf, mit der wir uns z.B. über die Markierung von Prozess-Beziehungen die Arbeit erheblich ereleichtern können, ohne dass aus dem Plugin zur Log-Aufbereitungs gleich ein EDR-Agent mit zu vielen Rechten und Pflichten werden muss.","original_language":"deu","persons":["Hilko Bengen"],"tags":["gpn20","23","2022","Security","gulaschprogrammiernacht","gpn","entropia"],"view_count":351,"promoted":false,"date":"2022-05-20T21:30:00.000+02:00","release_date":"2022-05-21T00:00:00.000+02:00","updated_at":"2025-06-16T09:30:03.348+02:00","length":2689,"duration":2689,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/23-8c75e66c-01ab-5611-af92-b6bcc1250a26.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/23-8c75e66c-01ab-5611-af92-b6bcc1250a26_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/23-8c75e66c-01ab-5611-af92-b6bcc1250a26.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/23-8c75e66c-01ab-5611-af92-b6bcc1250a26.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-23-linux-security-monitoring-mit-audit-events-schmerzen-reduzieren","url":"https://api.media.ccc.de/public/events/8c75e66c-01ab-5611-af92-b6bcc1250a26","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"5c50ee79-92a2-57f3-a4a5-34401a487fe8","title":"Smartphone Security - how to prevent audio surveillance","subtitle":null,"slug":"gpn20-38-smartphone-security-how-to-prevent-audio-surveillance","link":"https://cfp.gulas.ch/gpn20/talk/EALKLP/","description":"How to prevent using smartphones as Bugs - \nOverview of technologies and solutions.\n\nIn our world electronic espionage is constantly increasing.\nEven without expert knowledge is possible to turn modern smartphones into audio bugs.

How often has a system update left your machine in a broken state?  How often have you installed something on your machine just to try to \"make it work\"?  If you've moved to containers -- how much time have you spent trying to build \"the perfect base image\", and trying to maintain and wrangle your container build scripts?  How much work would still remain in front of you if you needed to reproduce a container image you snapshotted months ago?  If the answer to any of these questions troubles you -- we hope Warpforge will present a viable way to help fix all that.\n\nIn this talk, we'll introduce Warpforge, describe its objectives, give an overview of its declarative API, briefly cover how the guts work (spoiler: LOTS of hashes)... and ultimately, demonstrate it working, live, because seeing is believing.\n\nAlso in this talk, we'll discuss some conventions in package management and dynamic library linking -- and how we can do these differently, to produce systems of more reusable components.  We've started pursuing this together with building Warpforge, in a quest to make the most transparent and the most reusable systems possible.\n\nComparisons to Bazel/Blaze, Nix, Guix, and even to Docker all abound -- we hope you'll find some of the best parts of each visible in Warpforge, plus a few key innovations and user experience improvements of our own, together all in one bundle.\n\nWarpforge's approach to becoming a powerful \"Build Anything\" tool is to orient itself around providing the user with \"computation-addressable\" systems -- meaning: the same idea as content-addressable systems, but now extended to also apply to data processing and software compilation.  The use of cryptographic hashes to identify data has valuable properties for both security and for simplifying organization; in Warpforge, we apply that same idea to hashing the descriptions of environments and the computations we want to run within them, for similar victories in both security and simplification.  What Git did for source code version control, Warpforge wants to do for build instructions and data processing: decentralized, snapshottable, portable, and utterly agnostic to whatever you put in it.\n\nWarpforge is granular: although it uses containers for hermeticity, Warpforge lets you compose the filesystem from as many pieces as you want.  Warpforge features a freeform filesystem assembly syntax, which lets you state any content you want shall appear at any path you want.  This stands in stark contrast to most other container systems which limit you to monolithic \"images\" -- which invariably devolve into balls-of-mud, becoming difficult to maintain, difficult to introspect, and almost impossible to compose.\n\nWarpforge is a hackable tool.  Everything works via a JSON API.  There are both \"high\" and \"low\" level variants of this API: the \"high\" level lets you describe pipelines of computations, wired together with human-readable names of your choosing; the \"low\" level API always uses only content-addressable hashes for all data input, and always hashes things immediate upon output.  The interaction of these two APIs is the secret sauce: it makes a system that's both usable and also highly precise and highly auditable and reproducible.\n\nWarpforge aims to be a developer productivity tool, but at the same time, shift the culture: much like Git taught the world about hash trees, Warpforge wants to teach the world about reproducible builds.  Because every output is hashed, computation that fails to reproduce the same output becomes noticed immediately.\n\nWarpforge is a perfect tool for those interested in SBOMs (Software Bill Of Materials).  Because Warpforge identifies all inputs explicitly, it can very naturally produce an SBOM.  In fact, it does so in standard operation -- and unlike many other sytems, Warpforge doesn't just produce a descriptive, after-the-fact SBOM: Warpforge instructions are actually a load-bearing bill-of-materials by nature.\n\nWarpforge stops slightly short of doing package management.  However, Warpforge does offer some suggestions on ways to build package management systems... with more merkle trees, so that things remain reproducible, introspectable, and auditable even as they grow in systemic complexity.  (That's enough spoilers; come the talk to see how!)\n\nYou can find out more about Warpforge at http://warpforge.io/ and https://github.com/warpfork/warpforge/ .","original_language":"eng","persons":["Eric Myhre"],"tags":["gpn20","68","2022","Software \u0026 Infrastructure","gulaschprogrammiernacht","gpn","entropia"],"view_count":151,"promoted":false,"date":"2022-05-20T16:30:00.000+02:00","release_date":"2022-05-21T00:00:00.000+02:00","updated_at":"2025-04-29T10:45:09.019+02:00","length":2831,"duration":2831,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/68-afb29c11-5f9f-5370-ab74-b4ec270b39c2.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/68-afb29c11-5f9f-5370-ab74-b4ec270b39c2_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/68-afb29c11-5f9f-5370-ab74-b4ec270b39c2.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/68-afb29c11-5f9f-5370-ab74-b4ec270b39c2.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-68-build-anything-with-warpforge-reproducibly-decentralized-with-friends","url":"https://api.media.ccc.de/public/events/afb29c11-5f9f-5370-ab74-b4ec270b39c2","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"d86c1288-480d-5abf-94ad-cf96e194cba7","title":"Was ist eigentlich Farbe?","subtitle":null,"slug":"gpn20-92-was-ist-eigentlich-farbe-","link":"https://cfp.gulas.ch/gpn20/talk/VXHVG3/","description":"Wie funktioniert Farbwahrnehmung?

An evil maid attack is an attack on an unattended device, in which an attacker with physical access can backdoor the bootloader to grab the full disk encryption password. \n\nThis attack is easy to perform if the target uses an unencrypted boot partition. GRUB2 also supports encrypted boot partitions, where stage 1.5 of the bootloader decrypts the boot partition. Conceptual, evil maid attack is still possible, but it's harder to implement. I couldn't find a public exploit, so I wrote my own.\n\nIn this talk, I will explain the Linux boot process and the process of backdooring GRUB2 to get the full disk encryption password. The talk only covers Linux and GRUB2. There will be some slides, but most of the time you will see my terminal and some python code.","original_language":"eng","persons":["kmille"],"tags":["gpn20","32","2022","Security","gulaschprogrammiernacht","gpn","entropia"],"view_count":289,"promoted":false,"date":"2022-05-19T22:00:00.000+02:00","release_date":"2022-05-20T00:00:00.000+02:00","updated_at":"2025-07-13T12:15:04.183+02:00","length":2030,"duration":2030,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/32-ee3737d9-3232-56e7-8cad-7e4cbcfb4d4f.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/32-ee3737d9-3232-56e7-8cad-7e4cbcfb4d4f_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/32-ee3737d9-3232-56e7-8cad-7e4cbcfb4d4f.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/32-ee3737d9-3232-56e7-8cad-7e4cbcfb4d4f.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-32-poc-implementing-evil-maid-attack-on-encrypted-boot","url":"https://api.media.ccc.de/public/events/ee3737d9-3232-56e7-8cad-7e4cbcfb4d4f","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"b9440040-192b-5d27-9644-de6b01731379","title":"Rückengesundheit für Nerds","subtitle":null,"slug":"gpn20-90-rckengesundheit-fr-nerds","link":"https://cfp.gulas.ch/gpn20/talk/K9XUXV/","description":"In dem Vortrag soll es darum gehen zu erklären und vereinfacht darzustellen wie der die Wirbelsäule und die umliegende Muskulatur aufgebaut ist wie diese zusammen arbeitet und wie es letztendlich zu Rückenschmerzen kommt.\nWie man mit Rückenschmerzen umgeht sie vorbeugt oder selbst lindern kann.","original_language":"deu","persons":["Robin Dunn"],"tags":["gpn20","90","2022","Science","gulaschprogrammiernacht","gpn","entropia"],"view_count":2824,"promoted":false,"date":"2022-05-21T12:45:00.000+02:00","release_date":"2022-05-21T00:00:00.000+02:00","updated_at":"2025-07-07T13:00:05.629+02:00","length":3627,"duration":3627,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/90-b9440040-192b-5d27-9644-de6b01731379.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/90-b9440040-192b-5d27-9644-de6b01731379_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/90-b9440040-192b-5d27-9644-de6b01731379.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/90-b9440040-192b-5d27-9644-de6b01731379.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-90-rckengesundheit-fr-nerds","url":"https://api.media.ccc.de/public/events/b9440040-192b-5d27-9644-de6b01731379","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"e09b645b-e34d-5a84-9e84-70ca126d8661","title":"Automating Cookie Consent and GDPR Violation Detection","subtitle":null,"slug":"gpn20-49-automating-cookie-consent-and-gdpr-violation-detection","link":"https://cfp.gulas.ch/gpn20/talk/EDN8N9/","description":"The European Union’s General Data Protection Regulation (*GDPR*) requires websites to inform users about personal data collection and request consent for cookies.

We document the severity of this situation through an analysis of potential GDPR violations in cookie banners in almost 30k websites. We identify six novel violation types, such as incorrect category assignments and misleading expiration times, and we find at least one potential violation in a surprising 94.7% of the analyzed websites.\n\nWe address this issue by giving users the power to protect their privacy. We develop a browser extension, called CookieBlock, that uses machine learning to enforce GDPR cookie consent at the client. It automatically categorizes cookies by usage purpose using only the information provided in the cookie itself. At a mean validation accuracy of 84.4%, our model attains a prediction quality competitive with expert knowledge in the field. Additionally, our approach differs from prior work by not relying on the cooperation of websites themselves. We empirically evaluate CookieBlock on a set of 100 randomly sampled websites, on which it filters roughly 90% of the privacy-invasive cookies without significantly impairing website functionality.","original_language":"eng","persons":["Karel Kubicek"],"tags":["gpn20","49","2022","Security","gulaschprogrammiernacht","gpn","entropia"],"view_count":205,"promoted":false,"date":"2022-05-20T16:15:00.000+02:00","release_date":"2022-05-20T00:00:00.000+02:00","updated_at":"2025-06-23T01:30:02.810+02:00","length":3509,"duration":3509,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/49-e09b645b-e34d-5a84-9e84-70ca126d8661.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/49-e09b645b-e34d-5a84-9e84-70ca126d8661_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/49-e09b645b-e34d-5a84-9e84-70ca126d8661.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/49-e09b645b-e34d-5a84-9e84-70ca126d8661.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-49-automating-cookie-consent-and-gdpr-violation-detection","url":"https://api.media.ccc.de/public/events/e09b645b-e34d-5a84-9e84-70ca126d8661","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"10a73315-d0cf-5440-8fbe-2694cad76984","title":"The State of Analog Photography and how to build a bridge towards the Digital Domain","subtitle":null,"slug":"gpn20-45-the-state-of-analog-photography-and-how-to-build-a-bridge-towards-the-digital-domain","link":"https://cfp.gulas.ch/gpn20/talk/GDRCW8/","description":"Why it is still cool to expose silver halides to light and how to convert them into pixels.\n\nAnalog photography has often been claimed dead and obsolete.

Vielen Menschen ist bewusst, dass ihre Fingerabdrücke, Gesichter, oder Iris sie eindeutig identifizieren. Es gibt aber noch viele andere biometrische Merkmale, die zur Identifizierung und zur Inferenz von sensiblen Daten genutzt werden können. Dieser Vortrag gibt einen kurzen Einblick in die Verhaltensbiometrie (behavioral biometrics) und wie diese unsere Privatsphäre gefährden. Verhaltensbiometrie beschäftigt sich mit den einzigartigen Mustern, die sich daraus geben, wie wir uns bewegen, reden, oder denken. Ein Problem werden diese Muster, wenn sie gegen uns eingesetzt werden, z. B. um herauszufinden, welche sexuelle Orientierung eine Person hat. Wichtig wird diese Form der Biometrie, weil die Aufnahme unseres Verhaltens zunimmt und immer präziser wird. So können z. B. Mixed Reality Headsets heute schon die Handbewegungen, Kopfbewegungen und Augenbewegungen ihrer Nutzer aufzeichnen.","original_language":"deu","persons":["Simon Hanisch"],"tags":["gpn20","65","2022","Ethics, Society \u0026 Politics","gulaschprogrammiernacht","gpn","entropia"],"view_count":106,"promoted":false,"date":"2022-05-20T15:30:00.000+02:00","release_date":"2022-05-20T00:00:00.000+02:00","updated_at":"2025-03-25T19:00:04.102+01:00","length":1847,"duration":1847,"thumb_url":"https://static.media.ccc.de/media/events/gpn/gpn20/65-72305d90-a459-5da7-8ca5-947516e075c6.jpg","poster_url":"https://static.media.ccc.de/media/events/gpn/gpn20/65-72305d90-a459-5da7-8ca5-947516e075c6_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/gpn/gpn20/65-72305d90-a459-5da7-8ca5-947516e075c6.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/gpn/gpn20/65-72305d90-a459-5da7-8ca5-947516e075c6.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/gpn20-65-behavioral-biometrics-vs-privacy","url":"https://api.media.ccc.de/public/events/72305d90-a459-5da7-8ca5-947516e075c6","conference_title":"Gulaschprogrammiernacht 20","conference_url":"https://api.media.ccc.de/public/conferences/gpn20","related":[]},{"guid":"797d9bbd-bd63-5efe-ab2c-de91f035b4a0","title":"Gender Diversity in der Elektrotechnik - Die bunte Welt der Steckverbinder","subtitle":null,"slug":"gpn20-53-gender-diversity-in-der-elektrotechnik-die-bunte-welt-der-steckverbinder","link":"https://cfp.gulas.ch/gpn20/talk/Q8CWJM/","description":"Steckverbinder gibt es nur in weiblich und männlich, oder?

Allerdings noch sehr begrenzt. Als Arzt interessiert mich natürlich besonders der Gesundheitsdatenraum. Gegenwärtig stehen Medienbrüche, inkompatible Datenformate, fehlende digitale Akzeptanz der Datenweitergabe im Gesundheitswesen im Wege. \nDas soll sich ändern. \n2020 veröffentlichte die EU-Kommission ein Strategiepapier zur Datenökonomie: die EU-Datenstrategie (1). Auf 39 Seiten wird dort zur Entwicklung verschiedener Datenräumen in der Datenwirtschaft aufgerufen.\n\nAndrus Ansip, der Vizepräsident der EU-Kommission von 2017 beschreibt: „Es sollte ein freier Datenfluss zwischen Standorten, über Grenzen hinweg und innerhalb eines einheitlichen Datenraumes möglich sein. Wenn unsere Datenwirtschaft Wachstum und Beschäftigung hervorbringen soll, müssen Daten genutzt werden. Dafür müssen sie allerdings verfügbar sein und analysiert werden können.“ \n\nDie Fragen, muss das sein? und brauchen wir wirklich Wachstum?, entsprechen im gegenwärtigen ökonomischen Mainstream in etwa der Frage, muss ich vor der Darmspiegelung ein Abführmittel trinken. Hier gibt es kein Nein! \n\nIn Anbetracht der begrenzten Ressourcen und der Umweltkrise sind andere Fragen allerdings genauso wichtig: Was passiert im Gesundheitsdatenraum? Welche Schutzkonzepte für die Menschen sind vorgesehen? Braucht Datenökonomie im Gesundheitsdatenraum überhaupt Wachstum? Oder ist Datenökonomie vielleicht sogar der Weg, heraus aus dem Wachstum, hinein in eine nachhaltige Degrowth-Ökonomie? \nUnd als Arzt möchte ich noch hinzufügen, dass eine Vorsorgedarmspiegelung sein muss. \nSchauen Sie rein in meinen Talk, hier wird der Gesundheitsdatenraum ganzheitlich behandelt. \n\n(1) https://eur-lex.europa.eu/legal-content/DE/TXT/PDF/?uri=CELEX:52020DC0066\u0026from=DE","original_language":"deu","persons":["Dr. med.
