  • Introduction to virtio-networking and vhost-net

    In this post we have scratched the surface of the virtio-networking ecosystem, introducing you to the basic building blocks of virtualization and networking used by virtio-networking. We have briefly covered the virtio spec and the vhost protocol, reviewed the frontend and backend architecture used for implementing the virtio interface and have taken you through the vhost-net/virtio-net architecture of vhost-net (host kernel) communicating with virtio-net (guest kernel).

    A fundamental challenge we had when trying to explain things was the historical overloading of terms. As one example, virtio-net refers both to the virtio networking device implementation in the virtio specification and also to the guest kernel front end described in the vhost-net/virtio-net architecture. We attempted to address this by explaining the context of terms and using virtio-net to only describe the guest kernel frontend.

    As will be explained in later posts, there are other implementations for the virtio spec networking device based on using DPDK and different hardware offloading techniques which are all under the umbrella of the virtio-networking.

    The next two posts are intended to provide a deeper understanding of the vhost-net/virtio-net architecture. One post will be intended for architects providing a technical deep dive into the vhost-net/virtio-net and explaining how in practice the data plane and control planes are implemented. The other post intended for developers will be a hands on session including Ansible scripts to enable experimenting with the vhost-net/virtio-net architecture.

    If you prefer high level overviews we recommend you keep an eye out for the virtio-networking and DPDK introductions, to be published in the upcoming weeks.

  • 3 Infrastructure Compliance Best Practices for DevOps

    For most IT organizations, the need for compliance goes without saying. Internal corporate policies and external regulations like HIPAA and Sarbanes Oxley require compliance. Businesses in heavily regulated industries like healthcare, financial services, and public service are among those with the greatest need for strong compliance programs.

Mozilla: Firefox for Android Nightly and Surveillance ('Telemetry')

  • More Recommended extensions added to Firefox for Android Nightly

    As we mentioned recently, we’re adding Recommended extensions to Firefox for Android Nightly as a broader set of APIs become available to accommodate more add-on functionality. We just updated the collection with some new Recommended extensions, including… Mobile favorites Video Background Play Fix (keeps videos playing in the background even when you switch tabs) and Google Search Fixer (mimics the Google search experience on Chrome) are now in the fold. Privacy related extensions FoxyProxy (proxy management tool with advanced URL pattern matching) and Bitwarden (password manager) join popular ad blockers Ghostery and AdGuard. Dig deeper into web content with Image Search Options (customizable reverse image search tool) and Web Archives (view archived web pages from an array of search engines). And if you end up wasting too much time exploring images and cached pages you can get your productivity back on track with Tomato Clock (timed work intervals) and LeechBlock NG (block time-wasting websites).

  • Jeff Klukas: The Nitty-Gritty of Moving Data with Apache Beam

    In this session, you won’t learn about joins or windows or timers or any other advanced features of Beam. Instead, we will focus on the real-world complexity that comes from simply moving data from one system to another safely. How do we model data as it passes from one transform to another? How do we handle errors? How do we test the system? How do we organize the code to make the pipeline configurable for different source and destination systems? We will explore how each of these questions are addressed in Mozilla’s open source codebase for ingesting telemetry data from Firefox clients. By the end of the session, you’ll be equipped to explore the codebase and documentation on your own to see how these concepts are composed together.

  • This Week in Glean: glean-core to Wasm experiment

    On the Glean team we make an effort to move as much of the logic as possible to glean-core, so that we don’t have too much code duplication on the language bindings and guarantee standardized behaviour throughout all platforms. Since that is the case, it was counterintuitive for me, that when we set out to build a version of Glean for the web, we wouldn’t rely on the same glean-core as all our other language bindings. The hypothesis was: let’s make JavaScript just another language binding, by making our Rust core compile to a target that runs on the browser. Rust is notorious for making an effort to have a great Rust to Wasm experience, and the Rust and Webassembly working group has built awesome tools that make boilerplate for such projects much leaner.

  • Data Publishing @ Mozilla

    Mozilla’s history is steeped in openness and transparency – it’s simply core to what we do and how we see ourselves in the world. We are always looking for ways to bring our mission to life in ways that help create a healthy internet and support the Mozilla Manifesto. One of our commitments says “We are committed to an internet that elevates critical thinking, reasoned argument, shared knowledge, and verifiable facts”. To this end, we have spent a good amount of time considering how we can publicly share our Mozilla telemetry data sets – it is one of the most simple and effective ways we can enable collaboration and share knowledge. But, only if it can be done safely and in a privacy protecting, principled way. We believe we’ve designed a way to do this and we are excited to outline our approach here. Making data public not only allows us to be transparent about our data practices, but directly demonstrates how our work contributes to our mission. Having a publicly available methodology for vetting and sharing our data demonstrates our values as a company. It will also enable other research opportunities with trusted scientists, analysts, journalists, and policymakers in a way that furthers our efforts to shape an internet that benefits everyone.

Best Free and Open Source Mail Notification Tools

Email is arguably one of the most popular and useful functions of a Linux system. Fortunately, there is a wide selection of free email software available on the Linux platform which is stable, feature laden, and ideal for personal and business environments. A mail notification tool lets you know when new emails are received. A prominent feature of these tools is the non-obtrusive passive notification about important emails which will let you concentrate on your work and avoid unnecessary interruptions. When all you want to do is be notified when you have a new e-mail message the last thing you want is software chugging along in the background using up valuable system memory. Fortunately, the programs are lightweight in nature. Here’s our recommendations. All of the programs are free and open source goodness. Read more

  • Wine 5.18 is out making use of the new vkd3d-shader library

    The team hacking away on the Wine compatibility layer have put out another development build with Wine 5.18 now being made available. Wine 5.18 comes not long after the Wine team also released vkd3d 1.2, their Direct3D 12 to Vulkan translation layer and it seems part of the work was on integrations here.

  • Wine 5.18 Released With VKD3D 1.2's vkd3d-shader Usage

    Wine 5.18 is out as the newest bi-weekly feature development release. Wine 5.18 isn't the most exciting feature release in recent times but is notable in that Vulkan shader compilation is now done using the vkd3d-shader library. That library was introduced as part of this week's VKD3D 1.2 release for mapping Direct3D 12 over Vulkan. VKD3D 1.2 is much more capable than the prior v1.1 release from nearly two years ago. Wine 5.18 also converts the USER32 library to being of the portable executable (PE) format, the console no longer requires the curses library, support for display modes with various orientations, syntax fixes in the WIDL compiler, non-recursive makefiles now for the build system handling, and various bug fixes.
