Steven Rostedt is one of the original developers of the PREEMPT_RT patch; he started working in 2004 with the goal of turning Linux into a Real Time designed operating system. Although, the PREEMPT_RT patch still exists out of tree, several of its features have made it into the vanilla kernel. One of these features being Ftrace, the official tracer of Linux. Steven is the main author, developer and maintainer of Ftrace. He has also created ktest.pl, which is a testing framework within the Linux kernel, and is the one responsible for the kernel build option “make localmodconfig”. Outside of development, Steven has done numerous presentations around the world. He’s also been on the Kernel Summit program committee from 2010-2016, and is currently one the Linux Foundation’s Technical Advisory Board (TAB) members, which represents the kernel community to the foundation.
Steven joined VMware at the start of 2017 as one of the core developers at the heart of VMware’s Open Source Technology Center, focused on providing value and leadership in spreading open source expertise and culture across the company. Through VMware, Steven continues to work with various open source communities contributing his time to develop and enhance open source software.

Thomas is the founder and CTO of Linutronix GmbH, a privately held Germany based Linux/FOSS service provider. He’s also a Fellow at the Linux Foundation. Thomas leads the effort of mainlining the real-time preemption patch set and is (co)maintainer of the x86 architecture, the generic interrupt subsystem and the generic timer/timekeeping subsystem in the Linux Kernel. He works since more than 30 years in the embedded industry and still has a strong affinity for mission impossible.
Christian Brauner is a kernel developer and maintainer of the LXD and LXC projects currently working at Canonical. He works mostly upstream on the Linux Kernel maintaing various bits and pieces. He is strongly committed to working in the open, and an avid proponent of Free Software. Christian has been active in the open source community for a long time and is a frequent speaker at various large events.
Daniel Bistrot de Oliveira
Daniel is a kernel engineer in the real-time kernel team at Red Hat, where he works and contributes with the RT-related topics, like the PREEMPT_RT, SCHED_DEADLINE, and tracing. He is also a last-year Ph.D. Student at Scuola Superiore Sant’anna (Pisa-ITA) and UFSC (Florianopolis-BR), researching about formal modeling and verification applied to the real-time Linux kernel.

In his free time he enjoys outdoors with the family.
Enric Balletbò i Serra
Enric is an Embedded Linux Software Engineer for Collabora Ltd. working with major Industrial and Consumer customers. He has 10 years experience helping in the design and bringing up Computer on Modules (CoM) and System on Modules (SoM), mostly based on ARM processors running Linux. He currently maintains some of them in mainline Linux and is an active upstream contributor. Enric has a degree in Electronic Engineering from the University of Barcelona, and from the beginning has been interested in the Open Source world, especially in the Linux kernel. Both interests have allowed him to grow and get a deeper into the knowledge of the ‘Thin Red Line’ between software and hardware.
Rafael maintains the Linux kernel’s power management infrastructure and the core ACPI support code. He works at Intel Open Source Technology Center and focuses on the mainline Linux kernel development. He has been actively contributing to Linux since 2005, in particular to the kernel’s suspend/hibernate subsystem, power management in general (IO runtime PM framework, CPUFreq, CPUIdle, PM QoS, system wakeup framework etc.), hot-plug infrastructure, core ACPI support, core PCI support and more. Before joining Intel he worked at the Faculty of Physics of the University of Warsaw as a lecturer and IT specialist, he was a Linux and IT consultant and he ran a business of his own. Rafael holds a PhD in Physics from the University of Warsaw.

Kuhn began his work in the software freedom movement as a volunteer in 1992, when he became an early adopter of the GNU/Linux operating system, and began contributing to various Free Software projects. He worked during the 1990s as a system administrator and software developer for various companies, and taught AP Computer Science at Walnut Hills High School in Cincinnati. Kuhn’s non-profit career began in 2000, when he was hired by the FSF. As FSF’s Executive Director from 2001–2005, Kuhn led FSF’s GPL enforcement, launched its Associate Member program, and invented the Affero GPL. Kuhn was appointed President of Software Freedom Conservancy in April 2006, was Conservancy’s primary volunteer from 2006–2010, and has been a full-time staffer since early 2011. Kuhn holds a summa cum laude B.S. in Computer Science from Loyola University in Maryland, and an M.S. in Computer Science from the University of Cincinnati. Kuhn’s Master’s thesis discussed methods for dynamic interoperability of Free Software programming languages. Kuhn received the O’Reilly Open Source Award in 2012, in recognition for his lifelong policy work on copyleft licensing. Kuhn has a blog, and co-hosts the podcast, Free as in Freedom.
