Goodbye, Ubuntu: Samsung Kills Off Linux on DeX Project

Monday 21st of October 2019 07:20:00 AM
Samsung’s ambitious project to bring a full version of Ubuntu to its smartphones has been canceled, and the upcoming debut of Android 10 will remove even the existing beta versions currently up for testing.

Back in 2018, the South Korean smartphone manufacturer decided to push things to the next level with its DeX project and enable a full version of Linux on top of Android.

Samsung DeX is a special feature that allows flagships like the Galaxy S and Note to connect to larger screens using dedicated hardware and boost the productivity side of Android with mouse and keyboard support. Technically, Samsung DeX allows an Android phone to become an almost fully-featured PC that is connected to a bigger screen. A PC running Android, that is.

Last year, however, Samsung started a collaboration with Canonical, the makers of Ubuntu, to bring this Linux distro to DeX, essentially enabling Linux to run on Galaxy S and Note phones.

Leftovers: MX-19, Versalogic and Security

  • MX-19 “patito feo” released!

    We are pleased to offer MX-19 for your use. As usual, this iso includes the latest updates from debian 10.1 (buster), antiX and MX repos.

  • Compact Apollo Lake SBC aims sky high

    Versalogic’s Linux-ready, sandwich-style “Harrier” SBC has an Apollo Lake processor and a compact 95 x 55mm footprint, ECC RAM support, and ruggedization features designed for high altitude UAVs. Versalogic announced a Harrier SBC due in Q1 2020 that revises the compact, COM-and-carrier design of its three-year-old, Intel Bay Trail based Osprey, but advances to the newer Intel Apollo Lake. The Osprey is similarly bereft of real-world ports to enable easier real-world deployments in constrained environments.

  • Security updates for Tuesday

    Security updates have been issued by CentOS (jss and kernel), Debian (libpcap, openjdk-8, and tcpdump), Fedora (java-11-openjdk), openSUSE (libreoffice), Oracle (java-1.7.0-openjdk), Red Hat (java-1.7.0-openjdk, python, and wget), Scientific Linux (java-1.7.0-openjdk), SUSE (ceph, ceph-iscsi, ses-manual_en, dhcp, openconnect, and procps), and Ubuntu (exiv2, linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-raspi2, linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon, linux-hwe, linux-azure, linux-gcp, linux-gke-5.0, linux-snapdragon, and uw-imap).

  • Red Hat Ceph Storage RGW deployment strategies and sizing guidance

    Starting in Red Hat Ceph Storage 3.0, Red Hat added support for Containerized Storage Daemons (CSD) which allows the software-defined storage components (Ceph MON, OSD, MGR, RGW, etc) to run within containers. CSD avoids the need to have dedicated nodes for storage services thus reducing both CAPEX and OPEX by co-located storage containerized daemons. Ceph-Ansible provides the required mechanism to put resource fencing to each storage container which is useful for running multiple storage daemon containers on one physical node. In this blog post, we will cover strategies to deploy RGW containers and their resource sizing guidance. Before we dive into the performance, let's understand what are the different ways to deploy RGW.

  • OpenShift 4.2: New YAML Editor

    Through our built-in YAML editor, users can create and edit resources right in the Red Hat OpenShift Web Console UI. In the latest release, we’ve upgraded our editor to include language server support. What is language server support? The language server support feature uses the OpenAPI schema from Kubernetes to provide content assist inside the YAML editor based on the type of resource you are editing. More specifically, the language server support offers the following capabilities: Improved YAML validation: The new editor provides feedback in context, directing you to the exact line and position that requires attention. Document outlining: Document outlines offer a quick way to navigate your code. Auto completion: While in the editor, language server support will provide you with valid configuration information as you type, allowing you to edit faster. Hover support: Hovering over a property will show a description of the associated schema. Advanced formatting: Format your YAML.
