David Edmundson Improving KDE Plasma and GNOME's Tobias Mueller Speaks in ARES 2019

  • Improving Plasma’s Rendering (Part 1/2)

    Many parts of Plasma are powered by QtQuick, an easy to use API to render shapes/text/buttons etc.
    QtQuick contains a rendering engine powered by OpenGL making full use of the graphics card keeping our drawing super fast, super lightweight and in general amazing…when things work.

  • Tobias Mueller: Talking at ARES 2019 in Canterbury, UK

    The opening keynote was given by Alistair MacWilson from Bletchley Park. Yeah, the same Bletchley Park which Alan Turing worked at. He talked about the importance of academia in closing the cybersecurity talent gap. He said that the deficit of people knowing anything about cybersecurity skills is 3.3M with 380k alone in Europe, but APAC being desperately short of 2.1M professionals. All that is good news for us youngsters in the business, but not so good, he said, if you rely on the security of your IT infrastructure… It’s not getting any better, he said, considering that the number of connected devices and the complexity of our infrastructure is rising. You might think, he said, that highly technical skills are required to perform cybersecurity tasks. But he mentioned that 88% of the security problems that the global 5000 companies have stem from human factors. Inadequate and unfocussed training paired with insufficient resources contribute to that problem, he said. So if you don’t get continuous training then you will fall behind with your skill-set.

    There were many remarkable talks and the papers can be found online; albeit behind a paywall. But I expect SciHub to have copies and authors to be willing to share their work if you ask. Anyway, one talk I remember was about delivering Value Added Services to electric vehicle charging. They said that it is currently not very attractive for commercial operators to provide charging stations, because the margin is low. Hence, additional monetisation in form of Value Added Services (VAS) could be added. They were thinking of updating the software of the vehicle while it is charging. I am not convinced that updating the car’s firmware makes a good VAS but I’m not an economist and what do I know about the world of electric vehicles. Anyway, their proposal to add VAS to the communication protocol might be justified, but their scenario of delivering software updates over that channel seems like a lost opportunity to me. Software updates are currently the most successful approach to protecting users, so it seems warranted to have an update protocol rather than a VAS protocol for electric vehicles.

  • KDE + Qt 5.14 To Better Behave With Context Loss Around NVIDIA's Driver

    Currently when resuming from systemd suspend or switching back to the KDE desktop from an alternate VT, it's possible with the NVIDIA proprietary driver to see screen corruption or leakage of previous screen contents to areas of the lock screen / desktop. This annoying issue is now being better addressed with Qt 5.14.

Where’s the Yelp for open-source tools?

It would be great if there were a genuinely useful rating system that would help people discover excellent but less-visible open-source projects. But an easy way to work out which of the tens of thousands of projects are the vital, important ones – a software Yelp, if you will – doesn’t exist. It may never come to be. Hope springs eternal. Brian Profitt, Red Hat‘s Open Source Program Office (OSPO) manager, is working with others on a new project to make it easy to evaluate open-source projects: Project CHAOSS. This Linux Foundation project is devoted to creating analytics and metrics that help define open-source community health. Read more

Deepin Desktop Review: A Stylish Distro and Desktop Environment

In this Linux Desktop Environment review, we have a slightly controversial choice. Deepin, both as a distribution and as a Desktop Environment, is one that not everybody feels comfortable using and trusting. However, we’ll be setting that aside, dispelling some myths, and looking at the beautiful Deepin Desktop Environment (DDE), its user experience, some notable features, and giving some recommendations on where to experience it and who should use it.

The 10 Best Raspberry Pi Emulators Available in 2020

Raspberry Pi is a mini-computer as well as a marker board that comes with all the hardware built-in and is designed to make coding easier. You will find everything necessary, including RAM, CPU, and GPU on the boards. However, no matter how perfect Raspberry Pi looks, it isn’t capable of doing a lot of things, including running x86 apps. As a result, we need the Raspberry pi emulators to help us with the problems. One of the most amazing uses of these emulators is to play any of your favorite classic retro games using them on your Pi board. Read more
