Open Source Web Engine Servo to be Hosted at Linux Foundation
KubeCon, November 17, 2020 – The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced it will host the Servo web engine. Servo is an open source, high-performance browser engine designed for both application and embedded use and is written in the Rust programming language, bringing lightning-fast performance and memory safety to browser internals. Industry support for this move is coming from Futurewei, Let’s Encrypt, Mozilla, Samsung, and Three.js, among others.
“The Linux Foundation’s track record for hosting and supporting the world’s most ubiquitous open source technologies makes it the natural home for growing the Servo community and increasing its platform support,” said Alan Jeffrey, Technical Chair of the Servo project. “There’s a lot of development work and opportunities for our Servo Technical Steering Committee to consider, and we know this cross-industry open source collaboration model will enable us to accelerate the highest priorities for web developers.”

Linux Foundation Discounts Instructor-Led Courses
The Linux Foundation is home to many of the world’s most important open source projects, and also home to many of the top open source experts. Our instructor-led training courses are taught by hands-on practitioners who have used, built, and contributed to these projects for years. Instructor-led courses work differently to eLearning courses in that they take place at a specific time and are led by a teacher in real-time. The courses typically involve 3-4 full, consecutive days of instructional and lab time, meaning you can complete the training quickly and in a highly structured format. Having a live instructor also means you have the opportunity to ask questions and interact in real-time.
To increase access to this training, through November 24 all instructor-led training courses are discounted by 30-50%!

New CNCF Kubernetes Security Specialist Certification Now Available
The Linux Foundation, the nonprofit organization enabling mass innovation through open source, and Cloud Native Computing Foundation® (CNCF®), which builds sustainable ecosystems for cloud-native software, today announced the Certified Kubernetes Security Specialist (CKS), previously announced to be in development in July, is now generally available.
CKS is a two-hour, performance-based certification exam that provides assurance that a certificant has the skills, knowledge, and competence on a broad range of best practices for securing container-based applications and Kubernetes platforms during build, deployment, and runtime. The exam is taken remotely with a live proctor monitoring via webcam and screen sharing. Candidates for CKS must hold a current Certified Kubernetes Administrator (CKA) certification to demonstrate they possess sufficient Kubernetes expertise before sitting for the CKS. The certification remains valid for two years from the date it is awarded.
