  • Using BOINC with podman on Fedora

    Following the blog post Installing and configuring Folding@Home in Fedora by jorti, I would like to talk of BOINC too.

    I'm not a scientist, I only know that BOINC is a distributed computing system where you can donate CPU cycles of you computer to scientific projects. You can join various projects, from astrophysics to biology.

    You can find more informations here: https://boinc.berkeley.edu/

    On #Fedora you can find the boinc-client as well the boinc-manager in the official repository.

  • Using Keepalived for managing simple failover in clusters

    When you hear the term "high availability," you might think of large, complex environments with arcane technologies that are beyond the reach of the average sysadmin. But basic HA doesn't have to be complicated: in this series, you will learn about implementing basic, highly available services using Keepalived. I will take you through simple failover situations, as well as a more complex configuration used to respond to external events and trigger failovers. First, we will start with the fundamentals of Keepalived and the Virtual Router Redundancy Protocol (VRRP).

    This article is the first in a series of three articles covering everything from basic setup to advanced Linux HA concepts.

  • Red Hat: Why Automation Holds the Key to Security Governance and a Culture of Collaboration

    A typical FTSE 100 or Fortune 500 company has a vast and complex set of cybersecurity defenses in place; managed by multiple security operations teams spread across different business units and different geographies. A great deal of effort is put into securing an enterprise organization.

    Yet, despite the high level of diligence and preparation, security teams still lack a common framework and a common language that they can use to share designs, processes and ideas.

    This can be achieved by introducing automated workflows and processes based on a universal programmable language. However, the language must be accessible to all. It must be easy to understand and easy to write; so that information can be documented and shared amongst security professionals with different domain expertise.

    It should also support a completely unbiased approach, rather than a closed, proprietary system. This would upset the delicate balance of the complex security ecosystems already in place in large organizations. Finally, the system needs to be modular by design so that it can accommodate the vast, and growing, number of cybersecurity tools that large enterprises amass over time.

    IT and network operations teams have been using automated systems for some time. This is encouraging a culture of collaboration between different IT stakeholders. However, it’s an ongoing process and IT teams are always looking for the right combination of tools to support a comprehensive automation program.

Games: Debian-Based SteamOS, Lutris 0.5.5 and Critters for Sale

  • SteamOS Isn’t Dead, Just Sidelined; Valve Has Plans To Go Back To Their Linux-Based OS

    It’s big news for any PC gamer that has been frustrated with Microsoft’s erroneous-laden grip on operating systems for as far back as 1995; with it comes a monumental blow to privacy, not to mention mere control of your PC; updates have a tendency to start when they want to, new OS licenses must be purchased if you change hardware configurations, and applications that Microsoft doesn’t want you using are notoriously finicky to get working. Of course, users can simply switch over to Linux if they have had their fill of Microsoft. That switch comes with a slew of changes, however, and dropping reliable applications is a part of the grieving process that must take place when attempting to switch over your OS. Linux does host a plethora of open-source tools that can take the place of past applications; GIMP in lieu of Photoshop, for example. Yet the old applications are never truly replaced 1 for 1; it’s more of a bandage than anything else. Even with WINE and other techniques developed over the years to help users with Linux use Windows software, there are plenty of pitfalls and inconveniences that stymie any attempts to maintain Linux over Windows.

  • Lutris 0.5.5 Linux Game Manager Adds Humble Bundle Support, Initial VKD3D Support

    Lutris 0.5.5 is out today as the newest version of this Linux game manager to assist in installing both native and emulated games on Linux. Lutris continues to expand the scope of its "runners" for improving the Linux gaming experience. While the version 0.5.5 number may not seem like a big deal, there is actually a lot to find with the Lutris 0.5.5 update. Among the changes with Lutris 0.5.5 are: - Initial support for Humble Bundle integration.

  • Try out 'Critters for Sale', an exhilarating short horror visual novel with two episodes out now

    The absolutely exhilarating short horror visual novel Critters for Sale, which was originally released the first day of 2019, had its second chapter ("Goat") available for some time (Jun 2019, actually). Considering how such a hidden gem it is I was going to write about it, but Liam ended up doing it first in this GOL article. [...] It still maintains the same fever-dream like visuals, game mechanics and layout, consisting on a left HUD with some key information, a central upper section where all the images and animations are displayed, along with some point and click elements, and finally a center lower section where you see the dialogues and options to advance the story in the available directions. However, regarding the premise, now it features other characters and a different setting, but since this is one of those games where the less you know the better, I will only say that although we're only grasping the surface of the whole mystery, and while the tone of the story still keeps a personal scope, at this point it's clear that those responsible for the plot's main threat not only have enough power to influence the entire world, but also directly encompass the whole history of mankind...

Linux Kernel: Linux 5.7, Linux Security and Intel Gen9 Graphics On Linux

  • AMD Sensor Fusion Hub Laptop Driver Unlikely To Land For Linux 5.7

    While we were hoping to see the AMD Sensor Fusion Hub driver introduced in Linux 5.7 for improving the AMD Ryzen Linux laptop experience, that now looks quite unlikely. This driver has been sought after by AMD Linux laptop customers since 2018 for supporting the accelerometer, gyroscopic sensors, and other functionality on modern AMD laptops, similar to the Intel Sensor Hub. Patches for the AMD Sensor Fusion Hub (AMD-SFH) driver for Linux were posted in January and underwent a few rounds of review.

  • Amazon Engineer's Patch For Flushing L1 Cache On Context Switching Revved

    Earlier this month there was the proposal by a Linux kernel engineer for Amazon to flush the L1 data cache on context switches as another safeguard against the ever increasing CPU vulnerabilities. The motivation for flushing the L1d cache on context switches is driven as a result of Intel's data sampling vulnerabilities and this safeguard would be an opt-in feature for those paranoid about system security. Flushing the L1 cache would ensure the data is not being snooped or leaked following a context switch but with all of the cache flushing could significantly hamper the system performance.

  • HDR Display Support Coming To Some Intel Gen9 Graphics On Linux

    For the very common Intel "Gen9" graphics found on pretty much all current pre-Icelake hardware that is available through retail channels, high dynamic range (HDR) display support could soon be enabled under Linux for a subset of devices.
