  • Low-cost embeddable SDR occupies a mini-PCIe card

    The Fairwaves “XTRX” mini-PCIe SDR card is a low-cost embeddable SDR card aimed at high data rate apps including 4G/5G and “massive” MIMO.

    Fairwaves Inc.’s “XTRX” SDR mini-PCIe card, which launched on Nov. 30 at Crowd Supply, has earned more than 80 percent of its funding goal with one month remaining. The company claims the full sized mini-PCIe XTRX card (30 x 51mm) is the smallest commercially available SDR card. For comparison, the USB-interfaced LimeSDR Mini and RTL-SDR boards measure 69 x 31.4mm and 40 x 60mm, respectively.

  • Tiny quad-core Linux SBCs slim down and get an RPi-like carrier

    FriendlyElec has unveiled COM-like variants of its tiny, low-cost quad-core, Allwinner H3- and H5-based NanoPi Neo and Neo2 SBCs, plus an RPi style carrier.

    FriendlyElec’s new $8 “NanoPi Neo Core” and $25 “NanoPi Neo Core2” boards are low-profile variants of the company’s earlier 40 x 40mm NanoPi Neo and NanoPi Neo 2 SBCs, but with their large, topside USB and Ethernet connectors replaced by a third dual-row pin header. As a result, the new boards are more like computer-on-modules (COMs) than single-board computers (SBCs), in that they’re meant to be combined with off-the-shelf or custom carrier boards, such as FriendlyElec’s RPi 3-like Mini Shield (see farther below).

  • Top 5 Linux Music Players

    No matter what you do, chances are you enjoy a bit of music playing in the background. Whether you’re a coder, system administrator, or typical desktop user, enjoying good music might be at the top of your list of things you do on the desktop. And, with the holidays upon us, you might wind up with some gift cards that allow you to purchase some new music. If your music format of choice is of a digital nature (mine happens to be vinyl) and your platform is Linux, you’re going to want a good GUI player to enjoy that music.

    Fortunately, Linux has no lack of digital music players. In fact, there are quite a few, most of which are open source and available for free. Let’s take a look at a few such players, to see which one might suit your needs.

  • Udeler – A Cross-Platform Udemy Course Video Downloader

    I assume many of our readers are familiar with a number of online study education centers. Some of them focus on programming and computer science related topics alone while others have a wider topic range. Some websites are completely free or paid, and other offer both paid and free courses.

    Just like Khan Academy and Code Academy, Udemy is no newcomer to this domain. It’s a website where you can learn a variety of courses online at your own pace with some of them being available for free.

  • Thomas – A Simple Pomodoro Timer App for Linux

    One of the best methods you can implement to be more productive is time management. It allows you to keep track of how much time it takes you to get work done and how often you exceed your deadlines.

    Timer apps these days seem to have chosen a favorite technique to help users stay sharp and productive as is evident in apps like Gnome Pomodoro and Take a Break. The Pomodoro technique is a common pick.

KVM and Xen: Looking Glass, Irby Thompson, and New Release

  • Looking Glass Released For KVM Frame Relay, High Performance Windows VM Gaming

    Geoffrey McRae has published the code to the "Looking Glass" project he's been working on as a "extremely low-latency" KVM frame relay implementation for guests with VGA PCI pass-through.

    Long story short this allows for a graphics card PCI pass-through setup with a KVM guest whereby no separate monitor is needed but rather Looking Glass is like a virtual display for that GPU dedicated to the VM and displays the VM's rendered contents on your main monitor/GPU. Up to now those wanting to use a secondary graphics card pass-through setup with a virtual machine had to use a separate monitor, but with Looking Glass you can get by with a single monitor for the system.

  • Xen Project Contributor Spotlight: Irby Thompson

    The Xen Project is comprised of a diverse set of member companies and contributors that are committed to the growth and success of the Xen Project Hypervisor.

  • CoreOS’s Open Cloud Services Could Bring Cloud Portability to Container-Native Apps

    With the release of Tectonic 1.8, CoreOS provides a way to easily deploy container-native applications as services, even across multiple service providers and in-house resources.

    “We take open source APIs, make them super easy to consume, and create a catalog of these things to run on top of Kubernetes so they are portable no matter where you go,” said Brandon Philips, CoreOS chief technology officer.

  • Kubernetes 1.9 release brings greater stability and storage features

    The Kubernetes developer community is capping off a successful year with the release of Kubernetes 1.9, adding important new features that should help to further encourage enterprise adoption.

    Kubernetes is the most popular container orchestrator management software. It’s used to simplify the deployment and management of software containers, which are a popular tool among developers that allows them to run their applications across multiple computing environments without making any changes to the underlying code.

  • What’s new in Kubernetes containers

    Promoted to beta in Kubernetes 1.8 and now in production release in Kubernetes 1.9, the Apps Workloads API provides ways to define workloads based on their behaviors, such as long-running apps that need persistent state.

  • KDE Applications 17.12 Brings HiDPI Improvements, Rest Of KDE Games Ported To KF5

    KDE Applications 17.12 is now available as the newest six-month update to this collection of KDE programs making use of KDE Frameworks 5.

    KDE Applications 17.12 was the cut-off point by which only KF5-programs are permitted while those still making use of KDE4 libraries were forced to be dropped. That cleansing took place and Juk, KImageMapEditor, KMix, KGet, Kolf, Sweeper, and others were among those that saw KF5 ports while some older programs were dropped from the collection -- at least until seeing any KF5 port in the future.

  • VirtIO DRM Window Server Support: Letting Guest VMs Interface With Host's Compositor

    Collabora's Tomeu Vizoso is working on a interesting VirtIO DRM patch that lets clients running within a virtual machine communicate with a display compositor of the host system.

    Based off work done by Google on their ChromeOS kernel with a "virtio_wl" driver, Tomeu is adding support to the VirtIO DRM driver so that clients running within a virtual machine can communicate with the host system's compositor. Communication is done over the protocol supported by the compositor, e.g. Wayland. Similarly, the ChromeOS VirtIO Wayland work is about offering a virtual device used by a guest VM use a Wayland server on the host system transparently and just focused on Wayland support given the ChromeOS focus.

  • Linux Should Now Work For Some Knockoff PlayStation 3 Controllers

    While the Linux kernel has supported the official Sony PlayStation 3 controller as an input device, some of the off-brand/knockoff models haven't quite behaved correctly on Linux but that's now being rectified.

    Red Hat's Bastien Nocera has made a necessary change to the Sony HID code in the Linux 4.15 kernel to address these knockoff PlayStation 3 controllers as well as a change in BlueZ Git, for the upcoming BlueZ 5.48 release.

  • ZFS On Linux 0.7.4 Brings Linux 4.14 Support, Fixes

  • VKD3D Is Beginning Flight As Wine's Direct3D 12 To Vulkan Library

    Back at WineConf 2017 VKD3D was announced for bringing Direct3D 12 to Wine by implementing Microsoft's latest graphics API atop the Vulkan graphics API. The initial code for this new library is beginning to take shape.

    VKD3D is a long-term play for getting viable Direct3D 12 support working within Wine. As noted back at WineConf, this library is being developed independently of the Wine Git repository. This will potentially allow in the future others to make use of this D3D12-to-Vulkan code without pulling in Wine entirely, should porters look to this project for easing their process of getting Windows games running on Linux, etc.

  • Wayland's Weston Sees Patches For FreeBSD, Fractional HiDPI, Rust Bindings

    The current queue consists of a variety of fixes, with a sizeable hunk in the shared GLSL codebase.

    Whereas for individual drivers - i965 has a crash fix for when playing various Valve games, r600 and nouveau have tweaks in their compiler backends. Fast clears on radeonsi and RADV are better now, while the VAAPI encoding is playing nicely with GStreamer.

  • Mesa 17.2.7 Released For Those Not Yet On Mesa 17.3

    Emil Velikov of Collabora has announced the release today of Mesa 17.2.7 as the latest point release for this older stable branch of Mesa.

    If you are a devoted Linux gamer or at all care about the best features and performance, it's best you migrate to Mesa 17.3 if you are not habitually riding Mesa Git. But for those still using the Mesa 17.2 series from last quarter, the seventh point release is available.

KDE Partition Manager 3.3 and future work

Filed under
KDE

KDE Partition Manager 3.3 is now ready. It includes some improvements for Btrfs, F2FS, NTFS file systems. I even landed the first bits of new LUKS2 on-disk format support, now KDE Partition Manager can display LUKS2 labels. More LUKS2 work will follow in KPM 3.4. There were changes in how LVM devices are detected. So now Calamares installer should be able to see LVM logical volumes. Once my pull request lands, Calamares should also support partitioning operations on LVM logical volumes (although Calamares would need more work before installation and booting from root file system on LVM works). KPMcore library now only depends on Tier 1 Frameworks instead of Tier 3 (although, we will later require Tier 2).

Most of the work is now done in sfdisk branch. Currently, the only functional KDE Partition Manager backend uses libparted but sfdisk backend is now fully working (I would say RC quality). I would have merged in already but it requires util-linux 2.32 which is not yet released.
