Growing the Linux app Ecosystem at LAS 2019

The third Linux Application Summit (LAS) kicks off this week in Barcelona, Spain. Formerly organised under the GNOME project, known as Libre Application Summit, the new LAS is a joint effort between the KDE and GNOME projects. The aim of the conference is to encourage the growth of a vibrant Linux application ecosystem. Canonical are proud sponsors of LAS 2019, and are sending along a team to represent Ubuntu and Snapcraft.

The volunteers on the organising committee each have a long history in the Linux application community. They’ve all worked on platforms and infrastructure to enable new software development for Linux. I took some time to chat with some of the team, and what LAS means for them.

Aleix Pol, representing KDE, has worked on Linux applications for a while, and is hopeful for increased collaboration between application developers and platform maintainers. Aleix told me; “While we [GNOME and KDE] are sizeable organisations, we have massive tasks at hand. We need to create an environment where people can come and create their solutions for all of us.”

This applies both for application developers and those who work primarily on the platforms themselves. He continued; “With GNOME, we share pieces of software, we share users and we even share some of our dreams. Meeting, talking and collaborating can only be beneficial”. Aleix also highlighted the benefits of meeting in person at events like LAS, “There’s a very different kinds of visitor. The ones who have been around will be putting faces to nicknames and having these discussions that IRC and mailing lists can’t sustain”.

Events: KVM Forum 2019 and "Bar Charts for Diversity"

  • A recap of KVM Forum 2019

    The 13th KVM Forum virtualization conference took place in Lyon, France in October 2019. One might think that development may have finished on the Kernel Virtual Machine (KVM) module that was merged in Linux 2.6.20 in 2007, but this year's conference underscored the amount of work still being done, particularly on side-channel attack mitigation, I/O device assignment with VFIO and mdev, footprint reduction with micro virtual machines (VMs), and with the ability to run VMs nested within VMs. Many talks also involved the virtual machine monitor (VMM) user-space programs that use the KVM kernel module—of which QEMU is the most widely used.

  • Enhancing KVM for guest protection and security

    A key tenet in KVM is to reuse as much Linux infrastructure as possible and focus specifically on processor virtualization. Back in 2007, this meant a smaller code base and less friction with the other kernel subsystems, especially when compared with other virtualization technologies such as Xen. This led to KVM being merged into the mainline with relative ease. But now, in the era of microarchitectural vulnerabilities, the priorities have shifted, and the KVM's reliance on other kernel subsystems can be a liability. For one thing, the host kernel widens the TCB (Trusted Computing Base) and makes for a larger attack surface. In addition, kernel data structures such as the direct memory map give Linux access to guest memory even when it is not strictly necessary and make it impossible to fully enforce the principle of least privilege. In his talk "Enhancing KVM for Guest Protection and Security" (slides [PDF]) presented at KVM Forum 2019, long-time KVM contributor Jun Nakajima explained this risk and suggested some strategies to mitigate it.

  • Bar charts for diversity

    At the Linux App Summit I gave an unconference talk titles Hey guys, this conference is for everyone. The “hey guys” part refers to excluding people from a talk or making them feel uncomfortable – you can do this unintentionally, and the take-away of the talk was that you, (yes, you) can be better. I illustrated this mostly with conversational distance, a favorite topic of mine that I can demonstrate easily on stage. There’s a lot of diversity in how far people stand away from strangers, while explaining something they care about. The talk wasn’t recorded, but I’ve put the slides up. Another side of diversity can be dealt with by statistics. Since I’m a mathematician, I have a big jar of peanuts and raisins in the kitchen. Late at night I head down to the kitchen and grab ten items from the jar. Darn, all of them are raisins. What are the odds!? Well, a lot depends on whether there are any peanuts in the jar at all; what percentage is peanuts; whether I’m actually picking things randomly or not. There’s a convenient tool that Katarina Behrens pointed me to, which can help figure this out. Even if there’s only a tiny fraction of peanuts in the jar, there’s an appreciable chance of getting one (e.g. change the percentage on that page to 5% and you’ll see).

Linux on the MAG1 8.9 inch mini-laptop (Ubuntu and Fedora)

The Magic Ben MAG1 mini-laptop is a 1.5 pound notebook computer that measures about 8.2″ x 5.8″ x 0.7″ and which features an 8.9 inch touchscreen display and an Intel Core m3-8100Y processor. As I noted in my MAG1 review, the little computer also has one of the best keyboards I’ve used on a laptop this small and a tiny, but responsive trackpad below the backlit keyboard. Available from GeekBuying for $630 and up, the MAG1 ships with Windows 10, but it’s also one of the most Linux-friendly mini-laptops I’ve tested to date. [...] I did not install either operating system to local storage, so I cannot comment on sleep, battery life, fingerprint authentication, or other features that you’d only be able to truly test by fully installing Ubuntu, Fedora, or another GNU/Linux-based operating system. But running from a liveUSB is a good way to kick the tires and see if there are any obvious pain points before installing an operating system, and for the most part the two operating systems I tested look good to go. Booting from a flash drive is also pretty easy. Once you’ve prepared a bootable drive using Rufus, UNetbootin, or a similar tool, just plug it into the computer’s USB port, hit the Esc key during startup to bring up the UEFI/SETUP utility.
