  • Container and Kubernetes Security: It's Complicated

    Container technology is being increasingly used by organizations as a way to deploy applications and micro-services. The promise of containers is improved agility and portability, while potentially also reducing the attack surface. Though container technology can be helpful for security, it can also have its own set of risks.

    In a panel session at the recent Kubecon + CloudNativeCon EU event titled "Modern App Security Requires Containers" -- moderated by eSecurity Planet -- security experts from Cloud Native Computing Foundation (CNCF) project and Google debated what's wrong and what's right with container security.

  • Docker Defines Itself as the Open Choice for Containers at DockerCon 18

    Docker CEO Steve Singh kicked off his company's DockerCon 18 conference here today, offering the assembled crowd of container enthusiasts a clear vision of where Docker is going.

    For Docker Inc, the company behind the eponymous container system, a lot is at stake. This is the first DockerCon where the founder of the company, Solomon Hykes is not present. Hykes left Docker in March, as the company direction has increasingly focused on enterprise adoption and commercial market growth.

  • How to select the right enterprise Linux

    The decision to use any modern edition of that operating system, generally spoken as RHEL with a silent H, is usually based on a need for component stability, paid technical support, and long-term version support, said Red Hat's Ron Pacheco, director of global product management.

  • CentOS 7.4 & kernel 4.x - Worth the risk?

    The reasons why we have gathered here are many. A few weeks ago, my CentOS distro went dead. With the new kernel containing Spectre patches, it refused to load the Realtek Wireless drivers into memory. Moreover, patches also prevent manual compilation. This makes the distro useless, as it has no network connection. Then, in my CentOS 7.4 upgrade article - which was flawless, including the network piece, go figure - I wondered about the use of new, modern 4.x kernels in CentOS. Sounds like we have a real incentive here.

    In this tutorial, I will attempt to install and use the latest mainline kernel (4.16 when I typed this). The benefits should be many. I've seen improved performance, responsiveness and battery life in newer kernels compared to the 3.x branch. The Realtek Wireless woes of the disconnect kind (like a Spielberg movie) were also fixed in kernel 4.8.7 onwards, so that's another thing. Lastly, this would make CentOS a lean, mean and modern beast. Bravely onwards!

    [...]

    Now, I can breathe with relief, as I've delivered on my promise, and I gave you a full solution to the CentOS 7.4 Realtek issues post upgrade. I do not like to end articles on a cliffhanger, and definitely not carry the solution over to a follow-up article, but in this rare case, it was necessary. The mainline kernel upgrade is a topic of its own.

    The kernel installation worked fine, and thereafter, we seem to have gained on many fronts. The network issues are fully resolved, we can compile again, the performance seems improved despite worse figures in the system monitor, battery life and stability are not impaired in any way, and the CentOS box has fresh new life, wrapped in modern features and latest software. And none of this was meant to be in the first place, because CentOS is a server distro. Well, I hope you are happy. The one outstanding mission - Plasma 5. Once we have that, we can proudly claim to have created the ultimate Linux distro hybrid monster. Take care.

  • Windows 10 Will Finally Offer Easy Access to Linux Files [Ed: No, this is more WSL entrapment. They try to prevent people from using proper GNU/Linux with the actual kernel, either standalone or dual-boot. This is also about surveillance on one's files, keys, keystrokes, everything.]
  • Zowe Makes Mainframe Evergreen [Ed: Swapnil Bhartiya greenwashing and openwashing 2-in-1]
    Zowe also offers a vendor-agnostic experience allowing users to mix and match tooling and technologies. It provides interoperability, through the latest web technologies, products, and solutions from multiple vendors, and it allows developers to use the familiar, industry-standard, open source tools to access mainframe resources and services.
