Presentation delivered at LinuxCon China 2017. Open vSwitch (OVS) is a multilayer open source virtual switch. OVS is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces. OVN is a new network virtualization project that brings virtual networking to the Open vSwitch user community. OVN includes logical switches and routers, security groups, and L2/L3/L4 ACLs, implemented on top of a tunnel-based overlay network. In this presentation, we will provide an overview of the current state of the projects and their future plans, such as: - The current state of the Linux, DPDK, and Hyper-V ports - A status update on a portable BPF-based datapath - The latest stateful and OpenFlow features available in OVS - Performance and debugging enhancement to OVN - OVN features under development such as ACL logging and encrypted tunnels

During last year, we have seen the rise of LibraryOSes in the hypervisor world. Fast, scalable and light, they bring to hypervisors the resource efficiency of Containers while maintaining many of its well known isolation and manageability advantages. While most LibraryOSes are niche in what they do, OSv is designed to run almost any POSIX compliant application and just have a slight focus in the Java application. Which applications can we run? And why? What's the story with Java and what can users gain from it? And more importantly: How can Xen users and the Xen community at large benefit from OSv? Those are some of the questions that I intend to cover in this presentation.

What is special about community-industry collaboration around an open architecture like RISC-V is that the community can join development around key kernel subsystems in parallel with the semiconductor companies and manufacturers as they are producing the new chipsets and boards. Open silicon design, open board design, and open kernel software speeds bring-up of new boards and fosters greater innovation due to the diversity of talent contributing to the technology. For many kernel developers, tackling RISC-V is becoming harder to resist now that commercially viable and scalable hardware has begun to enter the market. A private beta program launched by the BeagleBoard Foundation in March 2021 placed an affordable, yet powerful prototype RISC-V board into the hands of Roman Shaposhnik. What did Roman do? He joined a diverse team of software and hardware hackers to tackle bringing up Linux on the new board. In this talk, Roman will tell you about his experience porting Alpine Linux and LF Edge EVE-OS to the new RISC-V architecture.

Presentation delivered at LinuxCon China 2017. Rethinking the Operating System. A new wave of Operating Systems optimized for containers appeared on the horizon making us excited and puzzeled at the same time. "Why do we need anything different for containers when traditional OSs served us well in the last 25+ years?" "Isn't Kubernetes just another package to install on top of my favorite distro?"" Will this obsolete my whole infrastructure?" are some of the questions this talk will shed some light on. Explore the journey SUSE made in rethinking the OS: From a conservative linux distribution to a platform that goes hand in hand with the needs of Microservices. You will get an insight at what lessons were learned during the intense development effort that lead to SUSE Containers as a Service Platform, how the obstacles along the way were lifted and why "Upstream first" is - and should always be - the rule.

Manually configuring mounts for containers to various network storage platforms and services is tedious and time consuming. OpenShift and Kubernetes provides a rich library of volume plugins that allow authors of containerized applications (Pods) to declaratively specify what the storage requirements for the containers are so that OpenShift can dynamically provision and allocate the storage assets for the specified containers. As the author of the Kubernetes Persistent Volume specification, I will provide an overview of how Persistent Volume plugins work in OpenShift, demo block storage and file storage volume plugins and close with the Red Hat storage roadmap. Presented at LinuxCon/ContainerCon by Mark Turansky, Principal Software Engineer, Red Hat Mark Turansky is a Principal Software Engineer at Red Hat and a full-time contributor to the Kubernetes Project. Mark is the author of the Kubernetes Persistent Volume specification and a member of the Red Hat OpenShift Engineering team.

Abstract The NetBSD rump kernel has been developed for some years now, allowing NetBSD kernel drivers to be used unmodified in many environments, for example as userspace code. However it is only since last year that it has become possible to easily run unmodified applications on the rump kernel, initially with the rump kernel on Xen port, and then with the rumprun tools to run them in userspace on Linux, FreeBSD and NetBSD. This talk will look at how this is achieved, and look at use cases, including kernel driver development, and lightweight process virtualization. Speaker bio Justin Cormack has been a Unix user, developer and sysadmin since the early 1990s. He is based in London and works on open source cloud applications, Lua, and the NetBSD rump kernel project. He has been a NetBSD developer since early 2014.

In the thrilling conclusion to 2023, ransomware groups had a banner year, really outdoing themselves in the "make everyone's life miserable" department. LockBit 3.0 took gold in the hacking olympics, followed by the plucky upstarts Clop and ALPHV/BlackCat. Apparently, 48% of organizations were feeling left out and decided to get in on the cyber attack action. Business services won the "most likely to get digitally mugged" award, with education and retail nipping at their heels. Hackers expanded their repertoire beyond boring old encryption to the much more exciting world of extortion. The US, UK and Canada took top honors in the "countries most likely to pay up" category. Bitcoins were the currency of choice for discerning hackers, because who doesn't love untraceable money?

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction.

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.
