  • 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.

  • NVIDIA Vulkan Beta Adds New KHR_driver_properties & KHR_shader_atomic_int64
    Not to be confused with the new NVIDIA Linux/Windows drivers that should be out today for RTX 2070/2080 "Turing" support and also initial RTX ray-tracing support, there is also out a new Vulkan beta driver this morning. The NVIDIA 396.54.06 driver is this new Vulkan beta and as implied by the version number is still on the current stable branch and not in the Turing era. But this driver release is quite exciting as it does bring support for two new extensions... These extensions are very fresh and not yet in the official Vulkan specification: VK_KHR_driver_properties and VK_KHR_shader_atomic_int64.
  • GeForce RTX 2080 Ti Linux Benchmarks Coming Today, NVIDIA Driver Bringing Vulkan RTX
    NVIDIA's review/performance embargo has now lifted on the GeForce RTX 2080 series ahead of the cards shipping tomorrow. I should have out initial Linux benchmarks later today, assuming Linux driver availability. As wrote about yesterday, just yesterday I ended up receiving the GeForce RTX 2080 Ti for Linux benchmarking. But, unfortunately, no Linux driver yet... But I am told it will be posted publicly soon with the Windows driver. Assuming that happens within the hours ahead, I'll still have initial RTX 2080 Ti benchmarks on Ubuntu Linux out by today's end -- thanks to the Phoronix Test Suite and recently wrapping up other NVIDIA/AMD GPU comparison tests on the current drivers.
  • Intel's New Iris Gallium3D Driver Picks Up Experimental Icelake Bits, GL Features
    One of the talks we are most interested in at XDC2018 is on the Intel "Iris" Gallium3D driver we discovered last month was in development. We stumbled across the Iris Gallium3D driver that's been in development for months as a potential replacement to their "i965" classic Mesa driver. But they haven't really detailed their intentions in full, but we should learn more next week. This is particularly exciting the prospects of an official Intel Gallium3D driver as the company is also expected to introduce their discrete GPUs beginning in 2020 and this new driver could be part of that plan.

Survey: Console Based Linux File Managers

The term ‘file management functions’ refers to the functions used to manage files, such as creating, deleting, opening, closing, reading from, and writing to files. In the field of system administration, Linux has bags of graphical file managers. However, some users prefer managing files from the shell, finding it the quickest way to navigate the file system and perform file operations. This is, in part, because console based file managers are more keyboard friendly, enabling users to perform file operations without using a mouse, and make it quicker to navigate the filesystem and issue commands in the console at the same time. A console application is computer software which can be used with a text-only computer interface, the command line interface, or a text-based interface included within a graphical user interface operating system, such as a terminal emulator. Whereas a graphical user interface application generally involves using the mouse and keyboard (or touch control), with a console application the primary (and often only) input method is the keyboard. Many console applications are command line tools, but there is a wealth of software that has a text-based user interface making use of ncurses, a library which allow programmers to write text-based user interfaces.
