This event is a Panel Discussion in Danish. Der er ved at blive etableret flere datacentre i Denmark af techgiganter, men hvilker fordele og ulemper ser vi for Danmark i den forbindelse? Det vil vi gerne diskutere med Lisbeth Bech-Nielsen, politiker, Poul-Henning Kamp, debatør, Peter Kofod, aktivist, Henning Mortensen, formand for Rådet for Digital Sikkerhed og Peter Christian Bech-Nielsen, chefre...

Presentation in Danish from the Danish MP Lisbeth Bech-Nielsen about this event: https://c3voc.de

This talk is in Danish. I dette oplæg får du en introduktion til, hvorfor det er vigtigt at beskytte privatlivets fred. Desuden får du en oversigt over reglerne i databeskyttelsesforordningen, som skal efterleves i digitale projekter. Endelig gennemgås de aktuelle problemer med tredjelandsoverførsler, som vanskeliggør rigtig mange digitale løsninger. Indlægget er på dansk. about this event: https:...

We used to wear fun T-shirts which showed OSI with 9 layers, the usual seven plus two extra: "Financial" and "Political". What if the joke is on us, and the T-shirt were correct? about this event: https://c3voc.de

Ole Tange har startet en krig mod sin fjernaflæste elmåler. I dette oplæg går vi dybere ned i sagen - både teknisk og juridisk. Sagen handler om fjernaflæste elmålere, men perspektiverne er langt større: Hvis vi kan bruge GDPR til at tvinge firmater til at respektere vores privatliv - selv det koster dem penge, så er der mange andre situationer, hvor det er relevant. Datatilsynet har endnu ikke af...

Bad software is everywhere. We have all experienced programs crashing, hanging, or doing the wrong thing. Software has become so unreliable that we almost expect it to fail. But it doesn't have to be this way. There are simple principles that we can follow in our code to eliminate virtually all bugs. Leading to happier users and easier maintenance. In this talk, I present six principles that in ob...

Flutter is a software development kit based on the Dart language enabling developers to create performant cross-platform applications. We'll have an introduction for people with some basic knowledge of Flutter or other cross-platform toolkits and later on a view on advanced topics. In this talk, we will have a look on performance-tuning, useful features as well as some background information on th...

European governments are proposing vague legislation that would likely require that messages be scanned for objectionable content before the message is sent (client-side scanning). This is bad. The legislation has been promoted under names like "fighting child sexual abuse", by lobbyists promoting a proprietary screening service. We don't have good reason to think such scanning would in fact preve...

In this presentation, we will take a look at this years badge and give some hints and ideas as to how it can be hacked about this event: https://c3voc.de

The BornHack 2022 team would like to welcome you to this year's BornHack event. We will walk over changes to the venue, schedule, and other information about the event itself. This is also an excellent opportunity to meet the teams behind BornHack. about this event: https://c3voc.de

3D Modellierung ist zu aufwändig? Und auf Thingiverse nichts passendes gefunden? In diesem Petit Foo zeige ich anhand eines Beispieles wie man einfach und schnell 3D Projekte umsetzt indem man Modelle von Thingiverse remixt und daraus eine passende Lösung kreiert. about this event: https://www.chaospott.de

It's over before you know it... this talk looks back at the event, explains how the tear-down works, highlights next years camps and gives a tanks to all the organizers on stage. What more can i say? Except that i need to enter at least 250 characters. I'll just blabber on and fill up th 🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈🌈...

The traditional talk by most or all operational teams about the infrastructure built for MCH2022. While the site has some infrastructure in place, a lot of it has to be built for this event. On the other hand there's also teams that just make things go away. MCH2022 can not be organised without a lot of temporary infrastructure. Join the operational teams and discover the new, the unexpected or th...

The MCH2022 design speaks for itself, but we would still nerd about it for a while. It is beautiful, colorful, generative, and has some physics ideas behind it. Some of it is obvious, but if you want to know all the hidden depths, this is the talk to visit. The triangulair MCH2022 design is a colourfull generative kaleidoscope with some hidden depths. In that way it reflects the hacker community....

Data keeps flowing! In Android, we have the concept of permissions, users feel confident that only if they turn on the permission, their data is shared. But what about an app silently sitting on your device with no permission whatsoever! What can that app know about you? In this talk, I'll talk about the Privacy Posture of Android! What kind of data is being collected, and how is it channelled and...

Using cryptography can give you easy assurances, keep data confidential and keep prying eyes from stuff where they should not be. However it's not magic. This talk is intended for programmers, users and software designers. This talk is about hardcore mathematics while you should not have to understand what the mathematics are but what they do. What does cryptography do: encrypt, decrypt, sign and...

A high bar set by earlier creations, a pandemic, a postponed event and chip shortages made for a great challenge and a wild adventure creating the MCH2022 badge. This talk explains how we pulled off our most advanced creation yet. We will tell you about the process of converting a vague idea into a piece of electronics, including the prototyping process and the difficulties we encountered. Bodging...

The whole world depends on Global Navigation Satellite Systems like GPS, Galileo, BeiDou and GLONASS. The technology behind these systems is fascinating and far more interested than generally presented. Although GNSS is super important, up to recently no good monitoring was publicly available. The "galmon.eu" project changed this. In this talk I cover: * How your phone really figures out where it...

Lightning talks are a 5 to 10 minute quick talk on an interesting subject. They can be with or without slides, and with or without proper preparation. if you weren't accepted in the main CfP, this is also a great opportunity to give an abridged version of your talk. These sessions will be available to sign up to later on, with details on the wiki: https://wiki.mch2022.org/Static:Lightning_Talks Li...

In 2017 (just before SHA2017) the Dutch healthcare sector came together to create Stichting Z-CERT, the Zorg Computer Emergency Response Team. A nonprofit to protect and advise the Dutch Healthcare sector. What started as a small startup has now grown into a scaleup with the ambitions to match. The COVID-19 pandemic restarted the discussion about whether or not healthcare is vital infrastructure....

My son Jurre and I got involved in helping less Tech-Savvy people find answers and recover precious data after someone close to them took their own life. This lecture describes our challenging and emotional journey as we hope to inspire others to follow our path.

The LIMITS workshop concerns the role of computing in human societies affected by real-world limits*. As an interdisciplinary group of researchers, practitioners, and scholars, we seek to reshape the computing research agenda, grounded by an awareness that contemporary computing research is intertwined with ecological limits in general and climate- and climate justice-related limits in particular....

So, you know how to "use" the ssh command line? You enter connection parameters like username, hostname or private key every time you need to connect? You manually log into the jump/bastion host when connecting to your target host? Then come to this session and learn how you can make your life easier and your work more efficient by using custom config files and a tiny little bit of preparation. So...

HowNormalAmI.eu is an interactive documentary that showcases how algorithms judge your beauty, age, gender, weight, life expectancy and emotions by simply looking at your face. The project not only shows how face recognition technology is entering our everyday lives, but it lets you experience these judgements yourself in a safe and privacy friendly way. This talk will zoom in on one algorithm tha...

Since early 2021, it has been impossible to buy most integrated circuits and various other components. I'll explain how and why this happened, why it's going to keep happening, and where the fragility of the electronics manufacturing ecosystem comes from. A terrible miscalculation by one unrelated industry (car manufacturing) caused the entire electronics market to fall apart in a spectacular way,...
