Flour Water Salt Elixir: The Fundamentals of Artisanal Hardware Hacking

What’s more fun than telling computers what to do? Combining programming with other activities you love! As a bread lover and amateur baker, that was hitting the sweet spot in sourdough fermentation using a Raspberry PI, sensors, and some 3D printing.
In this talk, you’ll learn about the fundamentals of interacting with the physical world from Elixir using the Nerves framework. You’ll hear fun stories about implementing bewitched protocols to get data out of sensors, and along the way we’ll talk about the basics of naturally-leavened bread. Hopefully you’ll walk away inspired to hack your hobby!

Everything about DNS you never dared to ask!

DNS is 37 years old, still today, one of the pillars of the modern Internet. Everything you do from deploying your app to twitter uses it. Yet, it's a black box for many of us. This talk covers the basics from resolvers to ICANN and the IETF we will a bird view and zoom into the exciting details.

This talk was born from an open space session I did at a local conference. I learned that it's a topic often touched on, but people often have many questions about it. The talk was always well received as it explained the fundamental concepts of the Internet and privacy of metadata in DNS and showed that it'd not been solved yet, while we are still discussing various ways with their pros and cons.

Explaining a concept people often feel they should already know about, plus the discussion of DNS privacy, always led to great feedback from the audience.

I started at a DNS management company about five years ago and had to learn a lot of this myself from the ground up.

Curio Collection of Web Protocols

Your average web application makes use of a lot of different protocols, most of them are quite old already. It’s a web app, so you use HTTP, which originates back to 1989. Sending Mails? SMTP is part of the game too. As you are also probably using a domain, DNS is as well.
As modern web developers often we don’t know much about these protocols. I claim that this is a fatal mistake. There is so much to learn, let’s explore how these works, let’s discover their quirks and learn what modern applications can learn from them.

WHOIS google.com? How big corps want your DNS data and how DNS-over-HTTPS helps them

DNS is a protocol as old as the Internet. Yet we only notice it when it’s not working, or when some company acquires a cool IP to run their own resolvers. But lately, there's a new, cool kid in town: DNS-over-HTTP, or DoH.
In this talk, I want to answer the question you all had when you read it the first time: Why? Why would anyone really want to do this? After we explore the motivation behind this, we’ll look a bit into the implementation details and discuss the pros and cons.
