  • 4 container usage takeaways from the 2019 Sysdig report

    You probably already knew that most of the containers created by developers are disposable, but did you realize that half of them are only around for less than five minutes? That and other fascinating details are available in the latest annual container report from Sysdig, a container security and orchestration vendor.

    This is the company’s third such report. The results are obtained from their own instrumentation collected from a five-day period last month of the more than 2 million containers used by their own customers. This means the results could be somewhat skewed toward more experienced container developers.

    Nevertheless, the report merits some scrutiny. Here are four important takeaways.

  • CNCF Adopts Longhorn Storage Project from Rancher Labs

    Based on 30,000 lines of Go code employed to create separate engine and management plane, Longhorn is significantly lighter than traditional storage software because it builds on existing Linux storage primitives, Liang says. It also doesn’t require a dedicated storage administrator to deploy and manage. It’s designed from the ground up to be used by the same team managing the Kubernetes cluster, he notes, adding modern storage hardware such as solid-state drives (SSDs) and NVMe backplanes made it easier to build Longhorn without compromising performance.

    While some applications might want to access block storage directly, Liang says Rancher Labs expects most organizations will layer a file system on top of Longhorn to access various forms of persistent storage.

  • Lessons From A Failed SaaS - Building SaaS #37

    In this episode, we talked about the things I learned from my SaaS project and some of the reasons why it failed to succeed financially. We dug into the technical and marketing challenges that I faced and what went wrong.

    I’m shutting down my side project, College Conductor. The SaaS never achieved a sustainable level of success. I started the site to help my wife with her college consulting business. As you can see from what follows, the site didn’t mange to deliver what she (or anyone else) really needed.

  • Setup Complete Qt SDK on Ubuntu Eoan Ermine

    Qt Software Development Kit (Qt SDK) includes Qt Creator IDE & Qt Framework Libraries with Full Code Examples among other things. On Ubuntu 19.10, if you want to develop GUI applications with Qt, you need to install that Qt SDK first with a C++ compiler. Installing it on 19.10 is slightly different to different to 18.04 as this involves configuring GNU GCC C++ compiler on 19.10. After setup, you will have a ready, complete Qt SDK with Creator, Designer, Linguist, and Assistant works with G++ compiler. I hope this will be useful for you all. Happy hacking!

Best Dual Pane File Managers for Linux

This article will cover a list of free and open source dual-pane and multi-pane file managers available for Linux. These file managers provide a broader look at various files and folders stored on your storage devices. They also improve overall productivity and file handling experience, especially if you regularly navigate through a lot of files using keyboard shortcuts. [...] These are some of the most popular dual-pane and multi-pane file managers available for Linux. While these file managers may seem cluttered and a little verbose at times, they are really useful if you want to quickly navigate through multiple files at once and run simultaneous file operations.

  • Two More X.Org Server Security Advisories Issued - Possible Privilege Escalation - Phoronix

    Trend Micro's Zero Day Initiative has uncovered two more security issues with the aging X.Org Server that as we roll into 2021 is still powering most of the Linux desktops. The security researchers found multiple input validation failures with the X.Org Server's XKB keyboard extension. Insufficient checks on different checks could lead to out-of-bounds memory accesses or buffer overflows.

    X.Org server security advisory: December 1, 2020
    
    
    Multiple input validation failures in X server XKB extension
    ============================================================
    
    These issues can lead to privileges elevations for authorized clients
    on systems where the X server is running privileged.
    
    * CVE-2020-14360 / ZDI CAN 11572 XkbSetMap Out-Of-Bounds Access
    
    Insufficient checks on the lengths of the XkbSetMap request can lead to
    out of bounds memory accesses in the X server.
    
    * CVE-2020-25712 / ZDI-CAN-11839 XkbSetDeviceInfo Heap-based Buffer Overflow
    
    Insufficient checks on input of the XkbSetDeviceInfo request can lead
    to a buffer overflow on the head in the X server.

    Xorg-server 1.20.10 has been released. This version fixes security issues that could lead to privilege escalation, or other problems.

Graphics: Intel, NVIDIA and Mesa

  • Intel Begins Preparing Linux Graphics Driver Support For Xe HP As "Gen12.5" - Phoronix

    Xe HP is Intel's discrete GPU aiming to compete against the latest-generation AMD and NVIDIA compute accelerators. Xe HP isn't scheduled to reach general availability until well into 2021 while now as they begin ramping up their sampling of Xe HP to potential customers, the Linux open-source driver support is preparing to roll-out. While Xe HP is about scaling up Intel Xe Graphics (Gen12), the Xe HP driver support is introducing it as a new "Gen12.5" target rather than just "Gen12" that is used by Tiger Lake / Rocket Lake / Xe LP.

  • NVIDIA Is Working On DMA-BUF Passing That Should Help Improve Their Wayland Support

    NVIDIA is working on allowing their proprietary driver to support passing buffers as DMA-BUF. In turn this should allow for better supporting their proprietary driver on Wayland compared to the EGLStreams mess. A Phoronix reader tipped us off to NVIDIA developer comments last month in response to a KDE EGLStreams bug. A bug report was opened regarding that restarting the compositing breaks the EGLStreams back-end for KDE's KWin.

  • Mesa Now 2~5x Faster For SPECViewPerf Following OpenGL Optimizations - Phoronix

    Well known open-source AMD Linux graphics driver developer Marek Olšák has just merged one of his largest set of optimizations in recent times: 2~5x faster performance for SPECViewPerf. SPECViewPerf is the common industry benchmark for measuring graphics performance for professional applications with benchmark viewsets from 3ds Max, CATIA, Maya, Solidworks, Siemens NX, and other programs. The performance when using Mesa drivers have been lagging but now thanks to common Mesa infrastructure improvements by Mesa, the performance is wildly improved.
