Canonical/Ubuntu: LTS, ROS 2, OSM and Fabrica

Ubuntwtoooo 20.04!
The next LTS release of Ubuntu has dropped and it’s frankly fantastic. We’re getting you up and running with it as quickly as possible in our main feature this month for those readers who are new to Linux or Ubuntu, and we’ll cover off the important new features you’ll be itching to try out. After nearly 16 years of continuous development this release isn’t here to innovate as much to refine Ubuntu.
The Gnome desktop – love it or hate it – feels super-slick and has received some much-needed optimisations over the past year. The theme has been polished to a sheen and icons refreshed. There will, of course, be the usual cascade of spin-off updates, ranging from the usual array of xyz-buntus but also downstream distros. The new Pop!_OS is already out and we’ve managed to squeeze a review into this issue. We’re very much looking forward to seeing how Mint 20 works out, too.

The State of Robotics – May 2020
With several countries finally emerging from lockdowns and markets showing signs of economic recovery, we’ve seen the newscycle steadily shift its focus away from Covid-19. And that will be reflected in our robotics recap as well. Let’s get right to it.

As is the ROS tradition, now that we’re nearing the ROS 2 Foxy release date, it’s time to name the G-version of ROS 2. The discussion thread has received a ton of suggestions. Our favorites so far are Galactic Gamera, Grumpy Gopherus, and Gutsy Gibba.
Head over to the Discourse page to provide your own recommendations. Something to keep in mind – not every user is a native English speaker, so the best release names are easy to pronounce. Glacial, glorious and global are quite practical. Glamorous, groundbreaking and geosynchronous… not so much.

OSM#9 Hackfest: the highlights
For this hackfest, the organisers decided to change the structure in a way that would facilitate hands-on sessions; with attendees playing with technology to learn and unlock new capabilities and skills – staying true to the very nature of a hackfest The event spanned three days of theory and workshop sessions, with an extra day for ecosystem-related presentations and leadership, and technical sessions happening in a parallel track for the full week.
The overall experience was great with active participation and every session felt like adding a piece to the puzzle to highlight the benefits that OSM can bring to telcos in a landscape that is rapidly moving towards network function virtualisation and containerisation. Participants were introduced to the end-to-end hackfest scenario on the first day. The next two days were all about how to deploy and operate network functions on physical machines (PNFs), virtual machines (VNFs) and Kubernetes-managed containers (KNFs), and how to do network slicing, auto-scaling and testing. Slides from all sessions can be found on the OSM wiki.

Canonical has a strong presence in the OSM leadership team, with CEO Mark Shuttleworth being a technical steering committee (TSC) member plus Beierl and Garcia from Canonical’s OSM engineering team as MDLs. Canonical’s vision is to bring better economics for data centres by providing smarter operations at a better price. This vision is very appealing to telecommunications providers that face complex network operations at scale. Our engagement in OSM aims at driving comprehensive design choices to drive better code and operations.
During the technical sessions, we presented the latest version of the OSM installer. The installer is able to deploy OSM using upstream OSM charms in high-availability mode on a user-provided Kubernetes, bootstrap a LXD cluster and link it to a virtual infrastructure manager (VIM) such as an Openstack cloud. Similarly, the installer can deploy OSM on a single-node, using Microk8s as the K8s substrate. The technical sessions also addressed the roadmap plan for OSM Release EIGHT that should be available in July 2020 and defined upcoming features to address production readiness. This marks an inflection point in OSM as the project enters a more mature stage.

Fabrica – Your self-hosted snap factory
There are many ways one can go about building snaps. You can do it on your local system, by manually running commands in a terminal window. If you have a developer account in the Snap Store, you can use the integrated build functionality to create snaps. You can also use Launchpad, Electron Builder or a range of CI/CD systems. And you can also run your own, self-hosted snap building factory!

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
