+## Abstract
+
+Historically, SMTP servers exchange emails using either an unencrypted (plaintext) connection or (since 2002) an encrypted connection based on the opportunistic STARTTLS protocol. At the same time SMTP servers, by design, did not validate the authenticity of another email server’s certificate; any random certificate were accepted. In short; confidentiality and integrity of (public) email transport cannot be guaranteed without taking extra measures. This is where DANE for SMTP comes in, as it enables email servers to determine up front whether or not another SMTP server supports an encrypted connection, while also providing the means of validating the authenticity of the other email server’s certificate.

+## Abstract
+
+In May 2013 at the Ripe 66 meeting in Dublin, at the maximum of solar cycle 24, I presented a short talk on mass emisions from the sun and it effects on our planet. Now, at the start the 25th solar cycle, it is a good moment to talk about Space Weather again and its effect on our environment. This talk doesn't need any special knowledege and will try to make you understand alarmist headlines better.

+## Biography
+
+After a period of seven years in the U.S., where he was active at the Information Technology Center at Carnegie Mellon University, software company mtXinu, and AT&T Bell Labs, Jaap returned to the Netherlands where he joined the NLnet, the first independent ISP in the Netherlands. Later he worked as a technical advisor for Stichting Internet Domeinregistratie Nederland (SIDN)
+
+Jaap went back and forth between scientific institutes, research labs, Internet service providers and registries in Europe and across the U.S., playing a key role as a global connector in the technical community.
+
+Throughout his career, Jaap has spent a generous amount of time sharing his knowledge with others and playing key roles in organisations such as the European Unix User Group, Advanced Computing Systems Association (USENIX), the Internet Engineering Task Force, the Internet Society, Internet Corporation for Assigned Names and Numbers (ICANN), Réseaux IP Européens (RIPE) and The Council of European National Top-Level Domain Registries (CENTR). Currently, he is a research engineer in the research and development group at NLnet Labs, focusing on IT development.
+
+Jaap always had ample interest in astronomy and was asked to help with the outreach project of the Stanford Solar Research Center and ending up maintaining the software of the solar monitors which are scattered around the world. The International Heliophysical Year 2007-2009 Education Center recognized his role in the the Space Weather Monitor Program. In 2014 he and the Society of Amateur Radio Astronomers received an Award of Excellence and the title "Hero in Solar and Space Physics".

+## Abstract
+
+In the operations world, there's a disconnect between the system administrators and the network administrators. The sys-admins have automation tools that don't integrate with the NFV/SDN standards used by "pure" network operations.
+
+In RFC 3535, the Internet Architecture Board stated that network equipment should provide defined models and a unified configuration API. This resulted in the standardization of YANG (a data modeling language) and NETCONF (an RPC protocol for configuration that carries instantiated YANG data).
+
+In this talk, I'll be discussing the configuration management landscape (from a system administrator perspective), explain a bit about YANG and NETCONF and how these two technologies can be used to automate network functions that are running on Linux instead of dedicated network equipment.
+
+## Biography
+
+Educated as a Systems and Network Engineer and having dabbled with DevOps-y things for years, Pieter's official title now is "Senior PowerDNS Engineer". As such, he works on the PowerDNS source code, the build/CI/packaging pipeline and running the infrastructure around the PowerDNS open source project.
+
+Pieter is also involved in the broader DNS operations and standards communities to make the Internet a better place.

+## Abstract
+
+In September this year, the seventh-generation Dutch national supercomputer called Snellius was inaugurated by Her Majesty the Queen Máxima.
+
+This immediately raises a number of questions:
+
+* What exactly is a supercomputer?
+* What are supercomputers used for?
+* What do supercomputers look like?
+* Where does the Netherlands stand in relation to Europe and the rest of the world?
+
+Since 1984, SURF has housed and managed the Dutch national supercomputer and has supported scientific researchers in making optimal use of it. We look back on more than 35 years of supercomputing in the Netherlands, but also take a brief look at the future.
+
+We also take a closer look at a number of aspects of Snellius: the tender; the (hardware) architecture; and the software environment, from both the administrator's and the user's perspective.
+
+## Biography
+
+Walter studied mathematics at the University of Amsterdam (UvA) and worked from the mid-eighties as a scientific programmer at the Center for Mathematics and Computer Science (CWI) in Amsterdam. In that capacity he used virtually all supercomputers in the Netherlands working on highly efficient implementations of algorithms in numerical mathematics and computational number theory.
+
+From 2001 he worked as a software engineer on predictive analytics software at Data Distilleries/SPSS.
+
+In 2007 he joined SURF as an HPC consultant, where he quickly became manager of the supercomputing team. He is currently responsible for the Research Services department, including the supercomputing team.
