  • Distro Hopping Doesn't Make Sense Too Me - YouTube

    I've been using Arch Linux since I first started with Linux and the idea of distro hopping jas just never appealed to me, not to say that I'll never leave Arch it's just that swapping for the sake of swapping seems kind of weird.

  • Quick Unboxing of my new Thelio Major

    I decided to show off the unboxing my my new desktop - I purchased a new Thelio Major desktop from System76. This particular unboxing was very awkward, the box was very tall and hard to position with my tripod. So please excuse the overall clumsiness of this entire video.

  • Run an Edge AI K3s Cluster on NVIDIA Jetson Nano Boards

    For several years I have worked with customers who wanted to use artificial intelligence (AI) in their products (mostly embedded hardware) but ended up relying on the cloud. With the advances of embedded platforms in recent years, this dependency is gradually disappearing, giving rise to the so-called Edge AI.

  • Traditional doesn’t mean staid: how banks should be innovating today

    When looking into a fiduciary for your assets, a bank with a long-standing history may seem like a stable, trustworthy choice. However, that very legacy may be one of the reasons large banks lose out to the competition in an age where customers are expecting open, quick, and real-time banking.

    Not unique to banks, big companies have a challenge of navigating legacies. These legacies do not just pertain to mainframes with monoliths on them, but also how they work. Along with their associates, senior managers should also show a desire to change. It’s harder to move fast if you are huge, but embracing an open culture from the top down can be a good starting point. I’ve seen huge amounts of talent, smart people, and big budgets hindered by a staid way of working. The strategy still needs to come from the top, but everyone should be enabled—and perhaps more importantly, empowered—to contribute.

    Regulations have forced banks to be more siloed, and now they continue to operate like that because it is easier, and traceable. IT in a bank was merely a cost center, a service provider until about 10 years ago. Technology was never an enabler, but seen as a cost-sink. We’re still struggling with this mindset today, even though we have continuously seen how technology can be a competitive differentiator.

    Large banks often don’t know where to start with some of their legacy, often the product of mergers and acquisitions. Then, you throw in a pandemic, during which the world of banking had to transform at a rapid pace to expand digital banking and chatbot services, and it ends up being a lot to take on all at once for large institutions. It can feel easier to keep legacy systems in place to stay afloat.

    Traditional banks still need help with faster transaction times, integrating artificial intelligence to improve the customer experience, and implementing agile ways of working for their IT teams. The hurdle lies in figuring out a way to get started. As a customer, I saw this innovation from Red Hat.

  • Quick-publishing of poudriere packages

    An essential tool in the FreeBSD porter’s arsenal (“porters” are the people who package third-party software, software like KDE Plasma, Haskell, ..) is poudriere, which is an evolution of the old tinderbox. It leverages ZFS and FreeBSD jails to do clean, consistent builds even on an otherwise occupied workstation, and can build for OS versions and architectures you’re not even running. Using the packages you’ve built can be slightly harder, so here’s some notes.

    Poudriere has a chapter in the porter’s handbook. There are straightfoward guides to setting it up, also on DigitalOcean.

    Most of those guides describe setting up nginx to serve the lovely and detailed build progress and results. I tend to follow the build progress in konsole, so I’m not interested in that part. What I do need to do is serve the resulting packages to other machines on my local network (e.g. my laptop) so that everything can enjoy the latest packages. That is doubly useful when trying out things like KDE Plasma on Wayland on FreeBSD, which needs plenty of testing and doesn’t work on all my hardware.

    tl;dr Install lighttpd, write 2-line configuration file, run lighttpd; on client, configure pkg to use what lighttpd serves.

  • Intel Already Started Working On Linux Driver Code For Lunar Lake - Phoronix

    While Intel 11th Gen Rocket Lake desktop processors are launching this month, Intel's open-source Linux driver developers known for their punctual support are already preparing early code around their 14th Gen "Lunar Lake" platform.

    Intel's punctual open-source/Linux support across desktop, mobile, and server platforms is one of the strong selling points for those preferring to use something on their PC besides Windows (Intel normally also does more for BSD/FreeBSD than other vendors as well). A year ago Intel began upstreaming their Rocket Lake Linux enablement code and that was quickly followed by Alder Lake, which we'll hopefully see launch before the end of the calendar year. Towards the end of 2020 Intel open-source developers were already working on the initial support around Meteor Lake while now as we end Q1'2021, there are patches beginning to surface for Lunar Lake, the successor to Meteor Lake and what will be Intel's 14th Gen client processors.

  • FLOSS Weekly 625: Endless Sky - Jonathan Steck

    Jonathan Steck joins Jonathan Bennett and Dan Lynch talk to about Endless Sky, an open source video game reminiscent of Elite and Escape velocity, and one that even hearkens back to Spacewar! On FLOSS Weekly, Steck and the show hosts talk about the game itself and the community around it. The project has attracted an interesting bunch of contributors, mainly through its presence on Steam as a free game. There are several challenges the project has overcome, from the sabbatical of the founder, to managing the continued growth and interest in the game. The game is addictive, and the conversation is just as good.

  • How To Install Dig on CentOS 8 - idroot

    In this tutorial, we will show you how to install the Dig on CentOS 8. For those of you who didn’t know, Dig (Domain Information Groper) is handy to perform DNS lookup and investigate DNS-related issues, right from the terminal. But for some reason, it doesn’t exist on the latest version of CentOS or RHEL. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the Dig on a CentOS 8.

  • The Linux Kernel & GNOME Desktop Preparing For Privacy Screen Support - Phoronix

    Over the past year there has been an uptick in Linux developers from different vendors working on laptop privacy screen support under Linux. When it comes to the support with newer Lenovo ThinkPad laptops, it looks like that kernel support could soon land and the GNOME desktop is already preparing to support this feature.  Select Lenovo laptops in recent years have offered a built-in "Privacy Guard ePrivacy Filter" for limiting the viewing angles of the laptop with a simple push of a button on the ThinkPad laptops. While the effectiveness of the "ePrivacy" feature is debatable in its current form and with the current work from home craze / limited travel making the feature less pressing at the moment, the Linux support is coming together.

  • Gigabyte Motherboard WMI Temperature Driver Queued Ahead Of Linux 5.13 - Phoronix

    Earlier this month I reported on a WMI temperature driver for Gigabyte motherboards being worked on by an independent developer. That "gigabyte-wmi" driver is now slated for inclusion in the upcoming Linux 5.13 cycle.  This driver exposes the Windows Management Instrumentation (WMI) temperature sensors under Linux. When writing originally about this new driver it was only tested on a Gigabyte X570 Aorus Pro WiFi motherboard but since then has been tested and confirmed to also be working on the likes of the Gigabyte's B550M DS3H, B550 Gaming X V2, and Z390 I Aorus Pro WiFi motherboards as well.

  • A New Gigabyte Motherboard WMI Temperature Driver Will Likely Arrive In Linux 5.13

    Linux users with newer Gigabyte and ASUS motherboards for AMD processors have to compile a out-of-tree version of the it87 to get hardware sensors and fan control working, and sensor support for the very newest motherboards is a shot in the dark even if you do that. That may change for Gigabyte-users with Linux 5.13 as a new, Gigabyte-specific WMI driver has been merged into the Linux kernels platform drivers git tree. It will likely be merged into Linux 5.13 when the merge window opens.

  • Rust Support In The Linux Kernel Undergoing Another Round Of Discussions

    Last month the initial infrastructure for allowing the Rust programming language to be used within the Linux kernel landed in the Linux-Next tree for more widespread testing ahead of its possible inclusion in the mainline kernel. Now a "request for comments" has been started again on the kernel mailing list around the prospects of Rust code for the Linux kernel.  Kernel developer Miguel Ojeda started this latest "RFC" proposal on the Linux kernel mailing list. The lengthy mailing list post outlines the beliefs of the involved developers over adding Rust code to the kernel, the benefits like improved memory safety, and more.

  • Google Supports Getting Rust Into The Linux Kernel

    It should come as little surprise -- especially given the recent news of Google allowing Rust to be used for Android system-level code -- but engineers at the search giant are in support of Rust code being used within the mainline Linux kernel.  In addition to yesterday's Rust RFC for the Linux kernel and that discussion still taking place on the Linux Kernel Mailing List, Google engineers on the Google Security Blog have penned their own piece on the matter.
