When it comes to writing code, there’s nothing we take more serious than authentication and security. Modern single page applications bring along new challenges. By using solutions like the OpenID Connect protocol and JSON Web Tokens we can improve the user experience when authenticating with your apps, providing a seamless authentication process.

In this talk I will try to explain in depth, the way JSON Web Tokens work and can be used to secure your single page apps. I will explain the difference between using opaque tokens and JWTs.

No specific previous knowledge is required, but it helps the audience has some experience with authenticating users.

The standards community develops specifications. The FOSS community implements standards. The FOSS community also develops industry standards. How does this the interaction function? And is it working well? How do policy makers interact with the FOSS community to set safety standards and other requirements? What is the relationship between standards-essential patents and FOSS? What comes first, specification or implementation? Where does innovation happen, and what is the platform to develop consensus on technical standards in a market segment? Based on research work at TU Berlin and for the Joint Research Center of the European Commission and the work of the Open Invention Network to protect key FOSS projects from patent litigation, the presentation will discuss the current state of the debate at the European and international level, and provide an outlook on how the roles and functions of standards-development organisations and the wider FOSS community are converging.

Did you ever miss that corner case bug? Maybe it was a negative integer, strange timezone conversion behaviour, off by one error or something entirely else. These subtle bugs are often hard to catch and are easily missed in test cases. You like me have probably ran into plenty of code utilising only happy path testing, only to later discover subtle bugs which are easily fixed once pointed out.
</div><div class="abstract">
This is where property based testing comes into the picture. In this talk I will focus on a wonderful Python library called Hypothesis but the concepts apply to other languages as well. Hypethesis is based on the same concept as the famous QuickCheck library for Haskell, which in turn have been ported a large number of languages. Hypothesis uses a wide range of input to find edge cases that you could otherwise easily miss, once it finds these cases it narrows down the input to the minimal breaking example to provide failures which are easier to understand.

The future of computing is tiny. Most computers are not desktop, laptops, tablets or mobile phones, but microcontrollers. Small, integrated systems with a few KB of RAM. And their presence is ever growing. Last year alone 31 billion (!) of them were shipped, up from 23 billion in 2015. And they get more capable every day. A modern embedded system has threads, can run Python or JavaScript, and use machine learning models. Why are you not developing for them yet?
</div><div class="abstract">
In this talk you'll learn that microcontrollers are not scary, that there's no magic involved, and that working in very constrained systems is actually very fun! You'll also learn a thing or two about getting things to run for years on a battery, try that with a web app. In this talk we'll use Mbed OS, the largest open source Real-Time Operating System for microcontrollers. In 2018 over 17,000 commits were landed in the project, it has over 400 unique contributors, and is licensed under the Apache 2.0 license.

User namespaces are at the heart of many interesting technologies that allow isolation and sandboxing of applications, for example running containers without root privileges and sandboxes for web browser plug-ins. In this tutorial, we'll look in detail at user namespaces, building up a basic understanding of what a user namespace is and going on to questions such as: what does being &ldquo;superuser inside a user namespace&rdquo; allow you do (and what does it not allow); what is the relationship between user namespaces and other namespace types (PID, UTS, network, etc.); and what are the security implications of user namespaces? We'll also explore some simple shell commands that can be used for creating and experimenting with user namespaces in order to better understand how they work. Along the way, there will hopefully be time for a few live demos.

Then there are the changes you can make to the kernel and bootloader configuration to speed things up, and finally, there are moderately advanced techniques such as using U-Boot in falcon mode.
