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 badges in a time where the pandemic and the chip shortage makes creating a cool gadget near impossible. This talk explains how we pulled off our most advanced creation yet (or not, depending on how things go...). 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.

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 is (so it can sell more expensive ads)

* How the "satellite ephemeris" is broadcast, what it means

* What is really in this 'assisted GPS'?

* The extensive ground infrastructure that is active 24/7 to determine the satellite orbits so GNSS is precise enough to tell which store you are in, or which side of the road you are driving on

* How GNSS are monitored in public by 100 Galmon.eu volunteers, running open source receivers all over the world

* And the research we enable

* Discussion of suitable hardware and GNSS-SDR that allows hackers to see each and every bit coming from the satellites

* A brief part on how GNSS can be spoofed and jammed, and the odd cryptography used to help detect or prevent this

The goal of this presentation is to expose the fascinating reality behind that little circle on your maps app, but also to explain how vulnerable this system is, which is why we need to monitor it closely.

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. With NIS2 the role and importance of Z-CERT will only grow from here on.

This talk is not to intended to be a corporate “Look how great we are and what kind of sexy products we have. BUY OUR STUFF.” No, we want to simply show what we do and what we learned in 5 years of being a CERT. This might help our (future) fellow CERT’s and the community.

This talk is not to intended to be a corporate “Look how great we are and what kind of sexy products we have. BUY OUR STUFF.” No, we want to simply show what we do and what we learned in 5 years of being a CERT. These lessons include:

- how to startup a sectoral CERT

- How to build a community of members of your constituency

- Connecting with fellow CERT organizations

- Tools of the trade

This might help our (future) fellow CERT’s and the community.

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.

After several talks about Hardware Hacking this talk will be one on a more serious matter. After someone takes their life and the police closes their case, the next of kin may still have questions that are left unanswered. This talk is about our journey from being nerds helping out with computer problems to specialists trying to help the next of kin find answers to questions they might still have.

And as this talk will be hosted for computer specialist who spend quite some effort making sure they are protected from external threat ask yourself this question; Will your loved ones be able to control the infrastructure or even have access to the family photo's when you pass away?

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.

In addition, we will also cover common best practices and improvements to your current SSH setup.

You will benefit the most from this talk, if you have used SSH before. SSH novices are welcome as well, SSH experts may drop by for the bad jokes.

The target audience for this talk is people with a beginner/intermediate understanding of SSH.

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. LIMITS 2022 solicits submissions that move us closer towards computing systems that support diverse human and non-human lifeforms within thriving biospheres.

For example, limits of extractive logics, limits to a biosphere's ability to recover, limits to our knowledge, or limits to technological "solutions".

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 that tries to deduce your Body Mass Index (BMI). The 'making of' will discuss the ethical questions it raised, the dubious science behind it, the dodgy data sources, and the surprising companies that are playing around with this technology.

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.

Dutch artist Tijmen Schep has created this interactive experience to reveal how we are increasingly being judged on our face. For example, dating websites like Tinder uses beauty scoring algorithms to match people who are about equally attractive. Services like HireVue claims to find the optimal job applicants based on their 'micro expressions'.

This talk will zoom in on one algorithm that tries to deduce your Body Mass Index (BMI) from your face. The 'making of' will discuss the ethical questions it raised, the dubious science behind it, the dodgy data sources, and the surprising companies that are playing around with this technology.

Since its launch in september of 2020 the project has been viewed over 185.000 times. If you want to find out if you're more attractive than the Spice girls, make sure you visit www.hownormalami.eu

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, meaning that for over a year now it's been impossible to buy many important electronic components, including most ICs. I'll talk about how the electronics component ecosystem is structured, why it's inherently fragile, and how everyone acting in their own best interest has made the problem worse. I'll also share some stories about working around supply issues at various companies and projects I've been involved with during this period.

Come hear a fireside chat about how car companies are trash, how you can build a world economy on shortsightedness, and how two conference calls can bring down the entire world's supply of essential parts.

A demonstration of the power of MQTT in combination with Node-RED. We'll also take a look at the "universal" Tasmota firmware for ESP8266 and ESP32-based devices. This all to hopefully make you enthusiastic to start building your own projects with these building blocks.

A demonstration of the power of MQTT in combination with Node-RED. We'll also take a look at the "universal" Tasmota firmware for ESP8266 and ESP32-based devices. This all to hopefully make you enthusiastic to start building your own projects with these building blocks.

MQTT is a very light message transport mechanism that uses a standard network connection and a subscribe-publish

protocol to get messages from one device to one or more others in the network in a structured manner.

Node-RED is a programming tool for wiring together hardware devices, APIs and online services very suited for working with MQTT messages.

Tasmota started as a universal firmware for ESP8266/8285 IoT-devices, now with added support for the ESP32 and it comes with MQTT-support out of the box.

With these tools, a raspberry pi and a few lines of script, we can start building home automation or whatever you want.
