• Lubuntu Planning Switch To Wayland, Porting Openbox To Mir

  Ubuntu derivative Lubuntu that is now using the LXQt desktop environment has laid out more of their plans to switch over to Wayland rather than the existing X.Org based session.

  In order to achieve their Wayland support with the LXQt desktop, they intend to port the Openbox window manager to using the Mir display server and also leveraging QtLayerShell. Mir, of course, has been focused on Wayland compatibility the past year and is becoming quite solid as of late with its core Wayland protocol support.

  We’ve been polishing the desktop more, but work has been blocked by the still ongoing Qt transition.

  The 16.04 to 18.04 upgrade has now been enabled! Please do let us know if there’s any issues. Here’s a video we made when 17.04 went End of Life; the instructions are still current.

  Our main developer, Simon Quigley, became an Ubuntu Core Developer this past Monday! He now has access to the entire Ubuntu archive.

Both Canonical and Red Hat emailed us with regards to the L1 Terminal Fault security vulnerability, which are documented as CVE-2018-3620 for operating systems and System Management Mode (SMM), CVE-2018-3646 for impacts to virtualization, as well as CVE-2018-3615 for Intel Software Guard Extensions (Intel SGX). They affect all Linux-based operating system and machines with Intel CPUs.

"It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS)," reads the Ubuntu security advisory.

• Deploying Kubernetes on Public Clouds is hard – or is it?

  Recently, there’s been talk about how Kubernetes has become hard to deploy and run on virtual substrates such as those offered by the public clouds. Indeed, the cloud-specific quirks around infrastructure provisioning, including storage, networking assets such as load balancers, and overall access control (IAM) differs from cloud to cloud provider. It is safe to assume that it also differs between your on-prem IaaS implementation or virtualized infrastructure and the public cloud APIs.

  With all the public Container-as-a-Service (CaaS) offerings available to you, why would you deploy Kubernetes to a generic IaaS substrate anyway? There are many reasons for doing so.
