  • Virtualization Management with SUSE Manager

    SUSE® Manager 4 is a best-in-class open source infrastructure management solution that lowers costs, enhances availability and reduces complexity for life-cycle management of Linux systems in large, complex and dynamic IT landscapes. You can use SUSE Manager to configure, deploy and administer thousands of Linux systems running on hypervisors, as containers, on bare metal systems, IoT devices and third-party cloud platforms. SUSE Manager also allows you to manage virtual machines (VMs).

    Virtualization is the means by which IT administrators create virtual resources, such as hardware platforms, storage devices, network resources and more. There are quite a few tools that enable the creation of virtual resources (such as Xen and KVM), but what about the management of those tools? That’s where SUSE Manager comes in.

  • Private and Air-Gap registry for openSUSE Kubic

    Sometimes there are occasions where direct internet access is not possible (proxy/offline/airgapped). Even in this setups it is possible to deploy and use Kubernetes with openSUSE Kubic and a local private registry.

    In this blog I will explain how to setup a local server which acts as private registry providing all the container images needed to deploy Kubernetes with openSUSE Kubic.

    Back in 2014, Google killed Google TV and announced Android TV, and as a result, introduced ADT-1, the first developer kit specifically designed for Android TV.

Improving the security model of the LVFS

There are lots of layers of security in the LVFS and fwupd design, including restricted account modes, 2FA, and server side AppStream namespaces. The most powerful one is the so-called vendor-id that the vendors cannot assign themselves, and is assigned by me when creating the vendor account on the LVFS. The way this works is that all firmware from the vendor is tagged with a vendor-id string like USB:0x056A which in this case matches the USB consortium vendor assigned ID. Client side, the vendor-id from the signed metadata is checked against the physical device and the firmware is updated only if the ID matches. This ensures that malicious or careless users on the LVFS can never ship firmware updates for other vendors hardware. About 90% of the vendors on the LVFS are locked down with this mechanism. Some vendors have to have IDs that they don’t actually own, a good example here is for a DFU device like the 8bitdo controllers. In runtime mode they use the USB-assigned 8bitdo VID, but in bootloader mode they use a generic VID which is assigned to the chip supplier as they are using the reference bootloader. This is obviously fine, and both vendor IDs are assigned to 8bitdo on the LVFS for this reason. Another example is where Lenovo is responsible for updating Lenovo-specific NVMe firmware, but where the NVMe vendor isn’t always Lenovo’s PCI ID. Read more

  • Qt Shader Tools Looks To Become Official Qt6 Module

    The currently-experimental Qt Shader Tools allows for graphics/compute shader conditioning and used by the in-development Qt graphics abstraction layer for supporting Vulkan / Metal / Direct3D / OpenGL APIs. Qt Shader Tools offers various shader features in preparing them for consumption by different graphics APIs. Qt Shader Tools is currently used ahead of time for QtGUI with Qt 5.14+. But for Qt 6.0, Qt Shader Tools is going through the appropriate steps for becoming a formal Qt 6 module for compiling and translating shaders between interfaces.

  • Python Positional-only parameters

    I have downloaded Python 3.8 and start to play around with those latest python functions. In this article, we will look at the Positional-only parameter syntax which is a function parameter syntax / to indicate that some function parameters must be specified positionally and cannot be used as keyword arguments which means after the / syntax we may specify a value for each parameter within that function.

  • For Loop in Python Explained With Practical Examples

    If you are just getting started to learn Python, you must be in search of something to explore for loop in Python. Of course, our list of free python resources should help you learn about it quickly. In either case, we shall help you learn more about the ‘for‘ loop in python using a couple of important examples.

Games: Pygame, The Long Dark, DXVK and Shovel Knight

  • Enable your Python game player to run forward and backward

    In previous entries in this series about creating video games in Python 3 using the Pygame module, you designed your level-design layout, but some portion of your level probably extended past your viewable screen. The ubiquitous solution to that problem in platformer games is, as the term "side-scroller" suggests, scrolling. The key to scrolling is to make the platforms around the player sprite move when the player sprite gets close to the edge of the screen. This provides the illusion that the screen is a "camera" panning across the game world. This scrolling trick requires two dead zones at either edge of the screen, at which point your avatar stands still while the world scrolls by.

  • Survival Mode in The Long Dark just got a lot bigger with the ERRANT PILGRIM update

    As promised, Hinterland Studio have released a huge update to the Survival Mode side of The Long Dark named ERRANT PILGRIM. It brings in a whole new region to explore, Bleak Inlet. Once a home to a thriving industrial Cannery, seismic activity cut-off Bleak Inlet from the rest of the Great Bear mainland. Exploring is not for the faint of heart, being Timberwolf territory but the treasures contained in the industrial complex may just be enough to warrant the journey.

  • DXVK Reportedly Going Into "Maintenance Mode" Due To State Of Code-Base

    While DXVK tends to be much-loved by Linux gamers for allowing more Direct3D 10/11 Windows games to run nicely on Linux with Wine or Proton (Steam Play) thanks to its fairly complete translation of D3D10/D3D11 API calls to Vulkan, it looks like Philip Rebohle is at least contemplating shifting it just into maintenance-mode. The DXVK lead developer recently commented that DXVK is "entering maintenance mode" and he doesn't want to make any significant changes or additions to the code.

  • Shovel Knight: King of Cards and Shovel Knight Showdown are out, completing the series

    Starting off with a successful Kickstarter crowdfunding campaign back in 2013 and growing into a massive multi-part 8-bit inspired world, Shovel Knight: Treasure Trove now finally finished. Note: Keys provided by GOG.com to us. Originally having a goal of $75,000 and a Linux/macOS stretch goal at $130,000 it proved to be popular ending on $311,491. It's taken six years for Yacht Club Games to get here starting with Shovel of Hope, followed by Plague of Shadows in 2015, Specter of Torment in 2017, and now King of Cards and Shovel Knight Showdown in 2019.
