Security
Ubuntu

Canonical released today new security updates for the Linux kernel and NVIDIA graphics drivers to address several vulnerabilities in several of the supported Ubuntu Linux releases.

The new security patches address three vulnerabilities affecting Ubuntu 20.04 LTS, Ubuntu 19.10 and Ubuntu 18.04 LTS. These include a vulnerability (CVE-2020-5963) discovered by Thomas E. Carroll in the NVIDIA Cuda grpahics driver, which could allow an attacker to cause a denial of service or possibly execute arbitrary code.

The other two security issues were an unspecified vulnerability (CVE-2020-5973) discovered in the NVIDIA virtual GPU guest drivers that could potentially lead to privileged operation execution and a race condition (CVE-2020-5967) discovered in the UVM driver in the NVIDIA graphics driver. Both these vulnerabilities could allow a local attacker to cause a denial of service.

Ubuntu: Split Personality Snaps, AVs and Ceph

Filed under
Ubuntu
  • Split Personality Snaps

    Broadly speaking, most snaps in the Snap Store fall into one of two categories, desktop applications and server daemons. The graphical applications such as Chromium and Spotify use desktop files, which ensure they can be opened on demand by any user via a menu or launcher. The server applications such as NextCloud and AdGuard-Home typically have systemd units, which control their automatic (background) startup.

    Taking an existing desktop application and converting it to an always-running appliance leads to some interesting engineering challenges. Applications and games tend to have expectations for what programs and services are accessible at runtime. which need mitigating. Application confinement in snaps on Ubuntu Core means some assumptions about file and device access may no longer apply.

    We will typically need to stand-up a configuration in which the application believes it’s running in a standard desktop environment. The application will also need the startup automated in an appliance setting, but launched on demand when in a desktop environment.

    We can be quite creative with snaps and build a “split personality” snap that can run both as a desktop application and as an appliance!

  • Open source holds the key to autonomous vehicles

    A growing number of car companies have made their autonomous vehicle (AV) datasets public in recent years.

    Daimler fueled the trend by making its Cityscapes dataset freely available in 2016. Baidu and Aptiv respectively shared the ApolloScapes and nuScenes datasets in 2018. Lyft, Waymo and Argo followed suit in 2019. And more recently, automotive juggernauts Ford and Audi released datasets from their AV research programs to the public.

    Given the potential of self-driving cars to considerably disrupt transportation as we know it, it is worth taking a moment to explore what has motivated these automotive players — otherwise fiercely protective of their intellectual property — to openly share their precious AV datasets with each other and with the wider world.

    [...]

    In the true spirit of open source, a symbiotic relationship is established from sharing AV datasets with the public. Researchers gain recognition for their novel insights. Developers build an industry repute for contributions to open source projects. And companies can integrate these new advancements into their own products, thus strengthening their portfolio and bringing new features to their customers faster.

    By allowing more people to contribute to the field, car companies can harness the economics of open source and benefit from faster software cycles, a more reliable codebase, and volunteer help from some of the brightest minds in the world.

    Automotive companies are beginning to understand this, and the industry will greatly benefit if this trend becomes the default.

  • Ceph storage on VMware

    If you were thinking that nothing will change in your VMware data centre in the following years, think again. Data centre storage is experiencing a paradigm shift. Software-defined storage solutions, such as Ceph, bring flexibility and reduce operational costs. As a result, Ceph storage on VMware has the potential to revolutionise VMware clusters where SAN (Storage Area Network) was the incumbent for many years.

    SAN is the default storage for VMware in most people’s minds, but Ceph is gaining momentum. In this blog, we will do a high-level comparison of SAN and Ceph to highlight how Ceph storage on VMware makes sense as the traditional data centre is moving towards a world of low operating costs through automation that leaves space for more R&D and innovation.

Linux Mint 20 “Ulyana” Is Now Available for Download, Here’s What’s New

Filed under
Ubuntu

The wait is finally over! Linux Mint 20 “Ulyana” is now available for download and you can get it right now from the official mirrors to enjoy all of its new features and improvements.

Linux Mint 20 entered beta testing a couple of weeks ago, but it looks like it’s a very stable release because the developers have just uploaded the final ISO images for the usual Cinnamon, Xfce and MATE flavors on the main download mirror, which you can download right now.

There’s no official announcement at the moment of writing because it takes time for all official mirrors to sync with the main download server, but we already know all the new features and improvements included in the Linux Mint 20 release.

Based on Canonical’s Ubuntu 20.04 LTS (Focal Fossa) operating system, Linux Mint 20 offers users long-term support with security updates until 2025, improved support for Nvidia GPUs and Nvidia Optimus, /home directory encryption, and a new file sharing app with encryption called Warpinator.

Ubuntu
  • Data science workflows on Kubernetes with Kubeflow pipelines: Part 1

    Kubeflow Pipelines are a great way to build portable, scalable machine learning workflows. It is one part of a larger Kubeflow ecosystem that aims to reduce the complexity and time involved with training and deploying machine learning models at scale.

    In this blog series, we demystify Kubeflow pipelines and showcase this method to produce reusable and reproducible data science.

    We go over why Kubeflow brings the right standardization to data science workflows, followed by how this can be achieved through Kubeflow pipelines.

    In part 2, we will get our hands dirty! We’ll make use of the Fashion MNIST dataset and the Basic classification with Tensorflow example, and take a step-by-step approach to turn the example model into a Kubeflow pipeline so that you can do the same.

  • MAAS 2.8 – new features

    This new release of MAAS brings three key new benefits:

    Virtual machines with LXD (Beta)
    Tighter, more responsive UX
    External/remote PostgreSQL database

  • Ubuntu Masters 3: the community expands

Ubuntu

Ubuntu derivatives are the customized or forked builds of the original Ubuntu operating system developed by Canonical. When it comes to choosing the best user-friendly distribution of Linux, everyone will suggest Ubuntu. Since the initial release of the first public version in 2004, Ubuntu rose higher and higher with its popularity.

Ubuntu is considered one of the most stable and beginner-friendly Linux distribution. Before the era of Ubuntu, many people had a misconception about Linux. The terminal commands and all that stuff seemed nightmare to them. But nowadays, anyone with basic knowledge can run almost any desktop distribution of Linux since many distros followed the same path as Ubuntu.

UBports GSI brings Ubuntu Touch to any Project Treble-supported Android device

Filed under
Ubuntu

The ability to boot an AOSP Generic System Image (GSI) on a compatible Android device is one of the best outcomes of Project Treble, but a similar achievement has yet to be made in the domain of generic kernel development. Google does mandate a minimum Linux kernel version requirement with each new release of Android, but you still can’t simply flash a generic ARM Linux distribution on your Android smartphone and expect it to work due to the fact that the majority of the Android devices are not using a mainline Linux kernel. There exists a community-driven project named UBports that aims to bring Ubuntu Touch (a mobile version of the popular Ubuntu Linux distribution) to Android devices, but their device support is fairly minimal to date.

XDA Recognized Developer erfanoabdi, however, is trying to tackle the situation from a different angle. Instead of waiting for device-specific patches to be landed in the mainline Linux kernel source tree, the developer has successfully created a GSI-esque, platform-agnostic Ubuntu Touch image that can be installed on any Project Treble compliant device.

UbuntuDDE | Review from an openSUSE User

Reviews
SUSE
Ubuntu

UbuntuDDE is a satisfactory Desktop Environment. Would I say it is the most beautiful? No, not a chance. I think it is fine though. What bothers me most about it is the very limiting feeling I get from it. I don’t feel attached to the desktop. I don’t feel like it is mine and things like not all applications respecting the dark theme just added more to that pile.

Despite my experience with the desktop. I think you should give it a try, in a VM or on actual hardware. After all, your experience may be far different than mine. It could be all roses and puppy dogs or maybe Kawaii cats hiding and appearing. After all, I am a biased openSUSE Plasma user that wants his bacon fried to a certain perfection. My tastes are different than yours so you should explore and find your Desktop Home.

Optimised authentication methods for Ubuntu Desktop

Still counting on passwords to protect your workstation? When set up properly, alternatives to passwords provide a streamlined user experience while significantly improving security. These alternative authentication methods can also easily be combined to create a custom and adaptive authentication profile. This whitepaper introduces three popular authentication methods that provide a solid alternative to passwords. Perhaps you’d like to configure your laptop for login using a YubiKey hardware token connected to a dock. Another option could be to login with a Duo push notification when not connected to the dock, but use a Google Authenticator one-time password when no network is available. Maybe you need a separate hardware token just for ssh authentication, and you always need to keep a long, complex password for emergency authentication should all other methods fail. All of these scenarios can be easily configured within Ubuntu. Read more

Open Hardware: Arduino, RISC-V and 96Boards

  • Arduino-controlled robot arm is ready to play you in a game of chess

    If you’re tired of playing chess on a screen, then perhaps you could create a robotic opponent like Instructables user Michalsky. The augmented board runs micro-Max source code, enabling chess logic to be executed on an Arduino Mega with room for control functions for a 6DOF robotic arm. The setup uses magnetic pieces, allowing it to pick up human moves via an array of 64 reed switches underneath, along with a couple shift registers. The Mega powers the robot arm accordingly, lifting the appropriate piece and placing it on the correct square.
