  • IBM Unveils ‘Open Source Cloud Guide’ at All Things Open

    One of the announcements made at this year’s All Things Open conference in Raleigh came on Monday when IBM unveiled an Open Source Cloud Guide, which offers a vendor and cloud agnostic view of open source developer tools.

    Unlike past ATOs, this year’s conference was a “hybrid” event, featuring in-person presentations before live audiences, as well as recorded presentations that were available only to online viewers. IBM’s announcement was made in one of the latter prerecorded presentations, called “The Growing Research that Open Source Owns the Future in Cloud,” with the announcement coming from Chris Ferris, IBM’s CTO of open technology.

    “The Open Source Cloud Guide, which highlights various use cases that are important in hybrid cloud environments, features the important open source projects in those areas and discusses how various clouds are using open source in their offerings,” Ferris and Todd Moore, IBM’s VP of open tech, wrote in a blog that was released on the same day. “By open sourcing the guide, developers are able to both use and contribute to the learnings and use cases.”

  • Automating host configuration with Red Hat Satellite and RHEL System Roles

    RHEL System Roles are a collection of Ansible roles and modules that provide a stable and consistent configuration interface to automate and manage multiple releases of Red Hat Enterprise Linux. Our wide variety of System Roles can automate many aspects of RHEL, saving you time and helping to configure your RHEL systems consistently.

    In this post, we’ll walk through how to combine Satellite and RHEL System Roles to provide an effective method of automating the management of RHEL systems.

  • Monitoring eBPF-based metrics

    If you're a Site Reliability Engineer, or do similar work, you've probably heard about eBPF. You might also have tried out a few bcc or bpftrace tools. Have you wondered how you can run these tools 24/7, log historical data and set alerts based on the measured metric values? This post will guide you through setting up Performance Co-Pilot, our monitoring solution for RHEL, and enabling eBPF sourced metrics on RHEL 8.

  • Developer workflows using the VS Code for Java extension 1.0 [Ed: IBM/Red Hat helping Microsoft instead of seeking to replace Microsoft's proprietary software that spies on users and encourages GPL violations]

    The 1.0 release of Language Support for Java by Red Hat on Visual Studio Code is now available on VS Code Marketplace. We'd like to take the opportunity to showcase a few workflows that really make it enjoyable to develop Java applications in Visual Studio Code (VS Code).

  • Digital transformation: 3 goals CIOs should prioritize

    CIOs are at the forefront of digital transformation, a position that’s not likely to change. Transformations are never static, although I admit that the word makes it sound otherwise. If your goal is to reach some new fixed state that will carry you over for many years to come, you’ve lost the battle. Ultimately, digital transformation should lead to a state that enables continual change and improvement.

    Today’s CIO is now more involved in the marketing functions than in the past, and for good reason. Where once the CMO may have outsourced to an agency, the CIO is now more central to external customer experiences, in large part because digital technology is creating connections between external and internal users. And unlike with past internal efforts, the CIO needs to worry about the technology used by people over whom they have no control: end customers.

    CIOs also need to figure out the newly emerging internal marketing needs. They’re often brought in to tackle specific tasks but are quickly called upon to solve a host of other challenges within their organizations.

Kernel: Slowdown, CephFS, and FS-Cache / CacheFiles

  • How a performance boost in Linux kernel for one family of Intel chips slowed its latest Alder Lake processors

    The mixture of performance and efficiency CPUs in Intel’s 12th-gen Core processors, code-named Alder Lake, hasn’t just been causing problems for some Windows gamers – it almost led to complications for Linux. Phoronix’s Michael Larabel noticed a performance hit in the kernel a fortnight ago – in a work-in-progress release candidate, we should stress – and a fix for the scheduling code landed a little later. It turned out the kernel suffered on Alder Lake chips due to a performance-enhancing tweak for another Intel processor family: the multiple-Atom-core-based Jacobsville. This year, Intel officially canned its Lakefield chips. These consisted of a performance core called Sunny Cove as well as Atom-class efficiency cores dubbed Tremont. Crucially, there are still multi-Tremont-core embedded processors out there, such as Snow Ridge. These are server and infrastructure-oriented components with up to 24 cores. The first proposed cut of kernel 5.16, specifically 5.16-rc1, contained a revision to the scheduler that makes it aware that some clusters of cores share a block of L2 cache – as seen in Snow Ridge and Jacobsville.

  • Testing the Linux Kernel CephFS Client with xfstests

    I do a lot of testing with the kernel cephfs client these days, and have had a number of people ask about how I test it. For now, I’ll gloss over the cluster setup since there are other tutorials for that.

  • Major Rewrite Of Linux's FS-Cache / CacheFiles So It's Smaller & Simpler - Phoronix

    As part of David Howells of Red Hat long-term work on improving the caching code used by network file-systems, he today posted a big patch series rewriting the fscache and cachefiles code as the latest significant step on that adventure. Howells posted a set of 64 patches for rewriting the kernel's fscache and cachefiles code. Linux's fsache is a general purpose cache used by network file-systems while cachefiles is for providing a caching back-end for mounted local file-systems. The Red Hat engineer has been working on this rewrite for more than the past year.

    Having the right speaker enclosure can make a big difference to sound quality, so it’s no surprise that customizable ones are a common project for those who treat sound seriously. In that vein, [zx82net]’s Universal Speaker Box aims to give one everything they need to craft the perfect enclosure.

    Building basic computers from the ground up is a popular pastime in the hacker community. [Kevin] is one such enthusiast, and decided to whip up a video interface for his retro Z80 machine.

  • The Calculator Charm: Calculatorium Leviosa! | Hackaday

    Have you ever tried waving your hand around like a magic wand and summoning a calculator? We would guess not since you’d probably look a little silly doing so. That is unless you had [Andrei’s] cool gesture-controlled calculator. [Andrei] thought it would be helpful to use a calculator in his research lab without having to take his gloves off and the results are pretty cool. His hardware consists of a PocketBeagle, an OLED, and an MPU6050 inertial measurement unit for capturing his hand motions using an accelerometer and gyroscope. The hardware is pretty straightforward, so the beauty of this project lies in its machine learning implementation.
