  • Why Chefs Collaborate in the Kitchen

    In a large commercial kitchen, for example hotels or cafeterias, chefs collaborate to create the recipes and meals. Sure, there is more than enough work for one person, and tasks are divided into chopping, mixing, cleaning, garnishing; but the recipe is collaboratively created.

    Suppose one chef broke away and created his or her own recipe? How would the kitchen maintain standards, tastes and reputation? Developing software using open source principles follows a similar theory.

    Red Hat is the second largest corporate contributor to the Linux kernel. This means Red Hat engineers and support staff are well versed and able to resolve customer issues involving the Linux kernel. Every application container includes part of the Linux distribution and relies on the Linux kernel, which is the center of the Linux Operating System.

  • CentOS 8 Status 17-June-2019

    Since the release of Red Hat Enterprise Linux 8 (on 07-May) we've been looking into the tools that we use to build CentOS Linux. We've chosen to use the Koji buildsystem for RPMs, paired with the Module Build Service for modules, delivered through a distribution called Mbox.

    Mbox allows us to run the Koji Hub (the central job orchestrator), and the Module Build Service in an instance of OKD that we maintain specifically for our buildsystem work. We have 2 instances of mbox; one for the primary architectures (x86_64, ppc64le, and aarch64), and one for the secondary architecture (armhfp). OKD lets us run those instances on the same hardware but in separate namespaces. The builder machines are separate from the OKD cluster, and connect back to the individual buildsystems that they're assigned to.

  • CentOS 8.0 Is Looking Like It's Still Some Weeks Out

    For those eager to see CentOS 8.0 as the community open-source rebuild of Red Hat Enterprise Linux 8.0, progress is being made but it looks like the release is still some weeks out.

    There's been the Wiki page detailing the state of affairs for CentOS 8.0. New today is a blog post summing up the current status. Progress is being made both on building the traditional RHEL8 RPM packages as well as the newer modules/streams. Koji is being used to build the RPMs while the Module Build Service with Mbox is handling the modules.

  • NVIDIA Brings CUDA to Arm, Enabling New Path to Exascale Supercomputing

    International Supercomputing Conference -- NVIDIA today announced its support for Arm CPUs, providing the high performance computing industry a new path to build extremely energy-efficient, AI-enabled exascale supercomputers.

  • NVIDIA Delivering CUDA To Linux On Arm For HPC/Servers

    NVIDIA announced this morning for ISC 2019 that they are bringing CUDA to Arm beyond their work already for supporting GPU computing with lower-power Tegra SoCs.

  • Nvidia pushes ARM supercomputing

    Graphics chip maker Nvidia is best known for consumer computing, vying with AMD's Radeon line for framerates and eye candy. But the venerable giant hasn't ignored the rise of GPU-powered applications that have little or nothing to do with gaming. In the early 2000s, UNC researcher Mark Harris began work popularizing the term "GPGPU," referencing the use of Graphics Processing Units for non-graphics-related tasks. But most of us didn't really become aware of the non-graphics-related possibilities until GPU-powered bitcoin-mining code was released in 2010, and shortly thereafter, strange boxes packed nearly solid with high-end gaming cards started popping up everywhere.

  • IBM Makes Takes Another Big Step To Hybrid Computing

    Today, IBM announced the ability to leverage its unique turnkey operating environment, IBM i, and its AIX UNIX operating systems on IBM Cloud. Both OSs debuted in the 1980s and have a long history with many IBM customers. In addition, IBM i remains one of the most automated, fully integrated, and low-maintenance operating environments. Extending both OSs to IBM Cloud will allow customers to expand their resources on-demand, to migrate to the cloud, to leverage the latest Power9 servers, and to leverage IBM’s extensive resources. IBM is rolling out the service first in North America for customers using IBM i or AIX on Power servers. In conjunction with the extension of the hybrid cloud platform, IBM also announced a program to validate business partners with Power Systems expertise.

Devices With Linux Support

  • Quest Releases KACE SDA & SMA Updates

    The update to 7.0 for KACE Systems Deployment Appliance is primarily about bringing a scope of endpoint management capabilities with new support for Linux devices to the table.

  • Rugged, Kaby Lake transport computer has a 10-port LAN switch with PoE

    Axiomtek’s Linux-ready “tBOX400-510-FL” transportation system has a 7th Gen Intel CPU and a 10-port managed switch with 8x M12-style 10/100Mbps PoE and 2x GbE ports. The rugged system also has 3x mini-PCIe slots and dual swappable SATA drives. Axiomtek has launched a fanless, Kaby Lake-U based transportation computer with a choice of power supplies designed for in-vehicle, marine, or railway applications. The rugged tBOX400-510-FL features a Qualcomm-driven, Layer 2 managed PoE switch with support for IP surveillance and video management applications. “Customers can connect IP cameras directly without installing an extra PoE switch, minimizing overall deployment costs and installation space onboard,” stated Axiomtek product manager Sharon Huang.

Software: Open Build Service (OBS) and Spotify 'App'

  • Introducing Open Build Service, Version 2.10

    We are pleased to announce the availability of Open Build Service (OBS) version 2.10! After more than one year of development, this new version of OBS brings a revamped web user interface, improved support for shipping your software in containers and integrating your package builds with source code management systems like GitLab and Pagure.

  • Spotify’s Snap App Was Outdated, But Now It Isn’t

    I’ll be honest: when Spotify arrived on the Snap store I thought: “hurrah”. Hurrah for an easier way to install the music streaming client (no need to futz around adding the Spotify repository like in the past) and hurrah for automatic background updates that ensure I’m always running the latest release. At least, that was the theory. Alas, the official Spotify for Linux Snap package has not been updated since April of this year. “Oh,” I thought, “I guess there hasn’t been an update to the Spotify Linux desktop client since then!” But there has — several updates, in fact!

KDE: Sponsorship, GSoC and KDE Connect

  • Couture Becomes a KDE Patron

    enioka Haute Couture is a software development house that creates complete and tailor-made solutions. enioka strives to return ownership of the software development and innovation to its customers. To that effect, it co-creates the software with its customers' teams to allow them to retain control of their projects in complex systems or organizations. "We are excited to welcome enioka Haute Couture as a Patron of KDE. They truly understand what it means to empower people when creating software; something KDE cares deeply about", said Lydia Pintscher, President of KDE e.V.

  • GSoC Milestone Update 1.1

    The second part of Milestone 1 for my Google Summer of Code 2019’s project porting KDE Connect to Windows involves enabling the SFTP plugin that ships in the linux build. The plugin allows you to navigate through your mobile device’s files (like you do with a file manager) ON YOUR DESKTOP! It makes use of sshfs to allow mounting the remote file system on your desktop. After that, you can use any file manager you like; heck, you can even use your terminal to have a walk through your mobile’s files. Once that is done, you can do literally anything with the mobile device’s files as you would do with the local filesystem: move files, copy them to your desktop machine, delete them, rename, anything!

  • KDE Connect sprint 2019

    From friday the 19th to sunday the 21st, we had the KDE Connect sprint. It's always a nice opportunity to meet the others working on KDE Connect, since we usually only talk to each other online.

  • KDE Connect is Being Ported to Windows 10

    Google Summer of Code 2019 is proving to be a bumper one for KDE Connect, the open source Android-to-PC integration suite. Last week we reported on the progress made by a GSoC student on KDE Connect for Mac. This week we bring word on a new KDE Connect Windows port. “Wait, isn’t KDE Connect already available for Windows?”, you might (rightly) ask — and the answer is yes, kind of!
