        Is your Linux PC struggling to handle certain resource-intensive programs? Or maybe you frequently find yourself staring at a loading icon for several minutes before your computer does something. Whatever the case, we all want our PCs to perform at their level best.

        Random Access Memory, or simply RAM, is crucial to having a performant PC, especially when running multiple programs or resource-intensive applications. Here are some ways to improve RAM performance on Linux.

      • Chris CoyierModern CSS in Real Life

        By any measure, CSS has gotten a lot better in recent years. It’s gotten more useful features, better interoperability between browsers, and become easier to learn thanks to a concerted push toward making CSS a cohesive system free of quirks and hacks.

        What matters though is the real world. Real websites. Real impact on the things we make and the people who use them.

        It’s working.

      • Computers Are Badradio on the tv

        Like many people in my generation, my memories of youth are heavily defined by cable television. I was fortunate enough to have a premium cable package in my childhood home, Comcast's early digital service based on Motorola equipment. It included a perk that fascinated me but never made that much sense: Music Choice. Music Choice was around 20 channels, somewhere in the high numbers, of still images with music. It was really ad-free, premium radio, but in the era before widespread adoption of SiriusXM that wasn't an easy product to explain. And SiriusXM, of course, has found its success selling services to moving customers. Music Choice was stuck in your home. The vast majority of Music Choice customers must have had it only as part of a cable package, and part of it that they probably barely even noticed.

        There’s an interesting parallel here, I think, to claims about how fast you can scaffold a website. X framework or Y host allows you to go from zero to a beautiful, functional (probably cloned from a template) website in “three easy steps”. The idea being, however implicit, that “in as little as three easy steps” you’re 90% of the way to something unique and special.

    • University of TorontoThere are two levels of isolation when building Linux packages

      Neither RPM nor Debian packages provide hermetic builds out of the box. For RPMs, mock provides an all-in-one solution that's generally very easy to use. Debian has the sbuild collection of tools (also, sbuild(1)) that, based on my reading, provide the tools you need to do this (I only recently found out about sbuild and haven't tried to use it). If there is a convenient mock-like front end to sbuild and its other tools, I haven't spotted it in Internet searches so far. Ubuntu does have a Setting up sbuild document that makes it look fairly straightforward.

    • dahliaOS: The Responsive and Secure Operating System You Need

      Having been a Linux user for what feels like an eternity, there have always been instances where I felt why do we have just Linux dominating. Granted it’s open-source which is great and of course, there’s the Unix family but we cannot exactly claim Unix to be fully open-source – considering the Open Group relationship.

      Even though we have the BSD family of truly free and open-source Unix operating systems including OpenBSD, NetBSD, FreeBSD, etc there is a need to be skeptical about these systems and their interoperability with the future of IoT devices that will continue to define the landscape of technology going into the future.

    • BSD

      • KenmaI did it, I switched to FreeBSD

        For about these past 3 months or so (perhaps even more?) I've become increasingly umconfortable with using Linux as my main operating system - from the oversized package counts and Python-unfriendliness (when it comes to desktop usage anyway) of the Debian family to the obligation to run the absolute latest versions of every base element of your system and update every week if you don't want to spend entire days trying to fix your installation in Arch and everything in between, I have been increasingly wanting to move to a more coherent system, an operating system that would be structured properly as opposed to a bunch of basic tools that have been patched on top of each other and an OS that would allow me to customize my workflow with as little extra fluff as possible while simultaneously keeping a base system that won't change until the next major release.

        ...and from there, enter FreeBSD.

        "The Debian Astro Blend continues to provide a one-stop solution for professional astronomers, enthusiasts, and hobbyists with updates to almost all versions of the software packages in the blend. astap and planetary-system-stacker help with image stacking and astrometry resolution. openvlbi, the open source correlator, is now included.

        "Support for Secure Boot on ARM64 has been reintroduced: users of UEFI-capable ARM64 hardware can boot with Secure Boot mode enabled to take full advantage of the security feature."

        Debian has three streams of development. The stable version adds security updates during its lifetime; however, one is stuck with quite old software until a new version lands.

        There is a second stream called testing, in which the software is much more recent and things are not overly prone to breakage.

        A third stream, unstable, is meant for highly experienced users, people who can keep fixing their systems if they break.

        Debian can be installed from a Blu-ray Disc, DVD, CD, USB stick, or via a network connection and images are available from the project website. Users can update by using the apt package management tool.

        Canonical MicroCloud provides an edge over IoT by performing computing tasks, thereby facilitating unattended, autonomous, and clustering features that resolve typical edge computing challenges. It trades the exponential scalability of public clouds for the security, privacy, governance, and low latency of decentralized environments.

        Discover how MicroCloud and HPE ProLiant Servers deliver next-generation compute solutions to power hybrid environments wherever it lives — from the edge to the cloud.

        Anbox Cloud is a Canonical offering which lets you stream mobile apps securely, at any scale, to any device letting you focus on your apps. It is tailor made for delivering mobile app content independent of the end user’s device capabilities by offloading the compute, storage, and energy intensive applications from end device to HPE Infrastructure.

        There is a need for communications service providers (CSPs) to look beyond mere connectivity to become digital service providers by optimizing their current legacy hardware to improve service and costs and create value from newer, innovative operating models and service offers. To achieve this, the CSPs require programmable infrastructure, operations automation, and the capacity to deliver on-demand services.

        These validated designs with Canonical Kubernetes and OpenStack are developed in close technical collaboration with Canonical and include container technology to allow multiple and isolated applications to run on a single OS and shared kernel. It also provides an integrated cloud-native platform that deploys an OpenStack cluster on dedicated physical servers.

      • UbuntuUbuntu Blog: Minimising latency in your edge cloud with real-time kernel

        From applications in telecommunications to edge cloud and industrial digital twins, experimenting with real-time capabilities in cloud technologies is a trend in the industry. Applications for the edge often have an additional requirement as they interact with real-time systems: they need to run deterministically. It means that time constraints their execution and interaction within the system.

      • SlashGearYou Can Install Linux On Your Old Nintendo Wii (But You Probably Shouldn't)

        A PC's operating system, when you drill right down to the nuts and bolts, is just a way of getting the user access to their desired functions. Whether it runs macOS, iOS, Windows, Android, or something else, a given device will use whichever system the creator happened to pick for it. It will, generally speaking, go through a wide range of iterations throughout its life, in the name of usability, security, future-proofing, and so on.

        More advanced users have the knowledge to migrate an OS to another hard drive, or to replace a given one with a relatively obscure one such as Linux's Ubuntu, if it's their preference. Tinkerers find that a lot of systems are surprisingly forgiving when it comes to such experimentation, a line of thought that has actually led to the installation of Linux on the Nintendo Wii.

        The L5 suspend resume is now very quick, incoming calls or texts arrive nearly as rapidly as before, imperceptible to the user in speed. Without suspend, the Librem 5 can idle for around 10 hours; with suspend running, you can get upwards of 20 hours.

      • Doug BrownUpgrading my Chumby 8 kernel part 5: graphics

        I started out with U-Boot. As a very basic overview of the LCD controller in the PXA168, basically you just set aside some of your RAM for a framebuffer, copy image data into it, tell the controller the format and address of the framebuffer, set up the clocking and timing, and turn it on. Then it just handles everything in the background for you.

        The steps I listed above are overly simplified — there is more stuff going on with the PXA168’s display controller. But it’s enough to get a splash screen working in U-Boot. I booted into the old kernel and dumped the LCD registers using devmem. Here’s an example of this process. The LCD_SPU_DMA_CTRL0 register contains a bunch of format configuration bits for the framebuffer, such as which bits are red/green/blue. It’s at offset 0x190 in the LCD controller, and the LCD controller is located at an offset of 0xD420B000, so I could dump the 32-bit register value with this command: [...]
