  • VMWare’s GPL woes continue

    For the last decade, VMware has been accused of illegally using Linux code in its VMware ESX bare-metal virtual machine hypervisor.

    While a German court has dismissed the case, the struggle may not be over.

    VMware was accused of illegally using Linux code in its flagship VMware ESX bare-metal virtual machine (VM) hypervisor.

    In 2011, the Software Freedom Conservancy, a non-profit organisation that promotes open-source software, discovered that VMware had failed to properly license any Linux or BusyBox, a popular embedded Linux toolkit, source code.

Learn about computer security with the Raspberry Pi and Kali Linux

Filed under

Is there a hotter topic in technology than securing your computer? Some experts will tell you that there is no such thing as perfect security. They joke that if you want your server or application to be truly secure, then turn off your server, unplug it from the network, and put it in a safe somewhere. The problem with that should be obvious: What good is an app or server that nobody can use?

That's the conundrum around security. How can we make something secure enough and still usable and valuable? I am not a security expert by any means, although I hope to be one day. With that in mind, I thought it would make sense to share some ideas about what you can do with a Raspberry Pi to learn more about security.

  • Rancher Labs Release Lightweight Kubernetes Distribution "k3s" for Edge, IoT and Telco Platforms

    Rancher Labs has announced a new open source project, k3s, which is a lightweight Kubernetes distribution that has been optimised towards running within resource-constrained environments, such as edge or IoT locations, or within telco and manufacturing systems.

    Darren Shepherd, co-founder and chief architect at Rancher Labs, stated in the k3s launch blog post that then new orchestration framework was created for running at the (network) edge, for example on ARM chips and IoT platforms, and for use within continuous integration systems where there is a requirement to minimise the speed of cluster initialisation and tear down. The name "k3s" is a play on the popular shortening of the word Kubernetes to "k8s", and the k3s GitHub repository states that the project is "5 less than k8s".

  • Linux Foundation leads work on open source framework for edge computing

    The Linux Foundation has announced the launch of LF Edge, an umbrella organization that will work to establish an open, interoperable framework for edge computing independent of hardware, silicon, cloud, or operating system.

    Arpit Joshipura, general manager, The Linux Foundation, said in a media statement that more than 60 global organizations were backing the initiative at launch.

    "This massive endorsement, combined with existing code and project contributions like Akraino from AT&T and EdgeX Foundry from Dell EMC, means LF Edge is well-positioned to transform edge and IoT (internet of things) application development," he said in a media statement.

    The market opportunity for LF Edge spans industrial, enterprise and consumer use cases in complex environments that cut across multiple edges and domains, Joshipura said.

  • ONS Evolution: Cloud, Edge, and Technical Content for Carriers and Enterprise

    The first Open Networking Summit was held in October 2011 at Stanford University and described as “a premier event about OpenFlow and Software-Defined Networking (SDN)”. Here we are seven and half years later and I’m constantly amazed at both how far we’ve come since then, and at how quickly a traditionally slow-moving industry like telecommunications is embracing change and innovation powered by open source. Coming out of the ONS Summit in Amsterdam last fall, Network World described open source networking as the “new norm,” and indeed, open platforms have become de-facto standards in networking.

    Like the technology, ONS as an event is constantly evolving to meet industry needs and is designed to help you take advantage of this revolution in networking. The theme of this year’s event is “Enabling Collaborative Development & Innovation” and we’re doing this by exploring collaborative development and innovation across the ecosystem for enterprises, service providers and cloud providers onkey areas like SDN, NFV, VNF, CNF/Cloud Native Networking, Orchestration, Automation of Cloud, Core Network, Edge, Access, IoT services, and more.

    A unique aspect of ONS is that it facilitates deep technical discussions in parallel with exciting keynotes, industry, and business discussions in an integrated program. The latest innovations from the networking project communities including LF Networking (ONAP, OpenDaylight, OPNFV, Tungsten Fabric) are well represented in the program, and in features and add-ons such as the LFN Unconference Track and LFN Networking Demos. A variety of event experiences ensure that attendees have ample opportunities to meet and engage with each other in sessions, the expo hall, and during social events.

Linux 5.1 Might Pick Up Support For Using Persistent Memory As System RAM

Filed under

While we are expecting to see more Intel Optane NVDIMMs this year that offer up persistent memory using 3DXPoint memory on the DDR4 bus for persistent storage, the Linux 5.1 kernel might pick-up support for treating this persistent memory back as traditional RAM if so desired.

Intel Optane DC Persistent Memory is expected to begin appearing in more servers this year for offering application-level persistent memory for use-cases like database servers, HPC, and other enterprise computing possibilities. If you are buying such NVDIMMs in the first place, chances are you planning to utilize the persistent memory for such purposes, but otherwise with Linux 5.1 there are patches pending to allow this PMEM to function as traditional system RAM.

GNOME Desktop: Parental Controls and More

  • Parental controls & metered data hackfest: days 1 & 2
    I’m currently at the Parental Controls & Metered Data hackfest at Red Hat’s office in London. A bunch of GNOME people from various companies (Canonical, Endless, elementary, and Red Hat) have gathered to work out a plan to start implementing these two features in GNOME. The first two days have been dedicated to the parental control features. This is the ability for parents to control what children can do on the computer. For example, locking down access to certain applications or websites. Day one began with presentations of the Endless OS implementation by Philip, followed by a demonstration of the Elementary version by Cassidy. Elementary were interested in potentially expanding this feature set to include something like Digital Wellbeing – we explored the distinction between this and parental controls. It turns out that these features are relatively similar – the main differences are whether you are applying restrictions to yourself or to someone else, and whether you have the ability to lift/ignore the restrictions. We’ve started talking about the latter of these as “speed bumps”: you can always undo your own restrictions, so the interventions from the OS should be intended to nudge you towards the right behaviour. After that we looked at some prior art (Android, iOS), and started to take the large list of potential features (in the image above) down to the ones we thought might be feasible to implement. Throughout all of this, one topic we kept coming back to was app lockdown. It’s reasonably simple to see how this could be applied to containerised apps (e.g. Snap or Flatpak), but system applications that come from a deb or an rpm are much more difficult. It would probably be possible – but still difficult – to use an LSM like AppArmor or SELinux to do this by denying execute access to the application’s binary. One obvious problem with that is that GNOME doesn’t require one of these and different distributions have made different choices here… Another tricky topic is how to implement website white/blacklisting in a robust way. We discussed using DNS (systemd-resolved?) and ip/nftables implementations, but it might turn out that the most feasible way is to use a browser extension for this.
  • GNOME ED Update – February
    Another update is now due from what we’ve been doing at the Foundation, and we’ve been busy! As you may have seen, we’ve hired three excellent people over the past couple of months. Kristi Progri has joined us as Program Coordinator, Bartłomiej Piorski as a devops sysadmin, and Emmanuele Bassi as our GTK Core developer. I hope to announce another new hire soon, so watch this space… There’s been quite a lot of discussion around the Google API access, and GNOME Online Accounts. The latest update is that I submitted the application to Google to get GOA verified, and we’ve got a couple of things we’re working through to get this sorted.

Managing changes in open source projects

Why bother having a process for proposing changes to your open source project? Why not just let people do what they're doing and merge the features when they're ready? Well, you can certainly do that if you're the only person on the project. Or maybe if it's just you and a few friends. But if the project is large, you might need to coordinate how some of the changes land. Or, at the very least, let people know a change is coming so they can adjust if it affects the parts they work on. A visible change process is also helpful to the community. It allows them to give feedback that can improve your idea. And if nothing else, it lets people know what's coming so that they can get excited, and maybe get you a little bit of coverage on or the like. Basically, it's "here's what I'm going to do" instead of "here's what I did," and it might save you some headaches as you scramble to QA right before your release. Read more
