Nvidia 440.64 Driver Released with Initial Support for Linux Kernel 5.6

Nvidia 440.64 comes about a month after the previous release, Nvidia 440.59, which added PRIME synchronization support for Linux kernel 5.4 LTS and later, as well as support for audio over DisplayPort Multi-Stream, and support for Nvidia High Definition Audio (HDA) controllers. This new version released today is only a small update that only introduces support for the Nvidia GeForce MX330 and Nvidia GeForce MX350 GPUs, as well as initial support for the upcoming Linux 5.6 kernel series by fixing some compilation bugs that prevented the Nvidia kernel module from building correctly.

  • Bring your ideas to the world with kubectl plugins

    kubectl is the most critical tool to interact with Kubernetes and has to address multiple user personas, each with their own needs and opinions. One way to make kubectl do what you need is to build new functionality into kubectl. Challenges with building commands into kubectl However, that’s easier said than done. Being such an important cornerstone of Kubernetes, any meaningful change to kubectl needs to undergo a Kubernetes Enhancement Proposal (KEP) where the intended change is discussed beforehand. When it comes to implementation, you’ll find that kubectl is an ingenious and complex piece of engineering. It might take a long time to get used to the processes and style of the codebase to get done what you want to achieve. Next comes the review process which may go through several rounds until it meets all the requirements of the Kubernetes maintainers – after all, they need to take over ownership of this feature and maintain it from the day it’s merged. When everything goes well, you can finally rejoice. Your code will be shipped with the next Kubernetes release. Well, that could mean you need to wait another 3 months to ship your idea in kubectl if you are unlucky. So this was the happy path where everything goes well. But there are good reasons why your new functionality may never make it into kubectl. For one, kubectl has a particular look and feel and violating that style will not be acceptable by the maintainers. For example, an interactive command that produces output with colors would be inconsistent with the rest of kubectl. Also, when it comes to tools or commands useful only to a minuscule proportion of users, the maintainers may simply reject your proposal as kubectl needs to address common needs. But this doesn’t mean you can’t ship your ideas to kubectl users.

  • PyIDM – An Open Source Alternative to IDM (Internet Download Manager)

    pyIDM is a free, open-source alternative to IDM (Internet Download Manager), used to download general files and videos from youtube as well as other streaming websites. It is developed using Python (requires Python 3.6+) and relies only on open source tools and libraries such as pycurl, youtube_dl, FFmpeg, and pysimplegui. It features multiple-connections, a speed engine (and it offers high download speeds based on libcurl); resume uncompleted downloads, support for fragmented video streams, support for encrypted/non-encrypted HLS (HTTP Live Streaming) media streams. Besides, it also supports scheduling downloads, re-using an existing connection to a remote server, and HTTP proxy support. And it allows users to control options such as selecting a theme (there are 140 themes available), set proxy, selecting segment size, speed limit, maximum concurrent downloads and maximum connections per download.

  • DRM Plugin crashes after openSUSE Tumbleweed update

    A few days ago openSUSE users started complaining about DRM Plugin crashes in Firefox after running a Tumbleweed update. Netflix requires the DRM plugin in Firefox to be able to play encrypted videos. The plugin would crash due to a bug in Firefox 73. While this bug affected not just openSUSE users, but everyone using Firefox 73, it became apparent to TW users as v73 landed in the Tumbleweed repo.

  • How Melissa Di Donato Is Going To Reinvent SUSE

    SUSE is one of the oldest open source companies and the first to market Linux for the enterprise. Even though it has undergone several acquisitions and a merger, it remains a strong player in the business. It has maintained its integrity and core values around open source. It continues to rely on its tried-and-tested Linux business and European markets, and generally shies away from making big moves taking big risks. Until now. SUSE appointed Melissa Di Donato as its first female CEO. She is making some serious changes to the company, from building a diverse and inclusive culture to betting on emerging technologies and taking risks. Soon after taking the helm last year, Di Donato spent the first few months traveling around the globe to meet SUSE teams and customers and get a better sense of the perception of the market about the company. Just like Red Hat CEO Jim Whitehurst, Di Donato didn’t come to the company from an open source background. She had spent the last 25 years of her career as a SUSE customer, so she did have an outsider’s perspective of the company. “I am not interested in what SUSE was when I joined. I am more interested in what we want to become,” she said.

  • Experimental feature: snap refresh awareness and update inhibition

    We’d like to follow up on last week’s article about parallel installs for classic snaps with another bleeding-edge topic. Today, we will discuss snap refreshes. By design, snaps come with automatic updates, and by default, the update (refresh) frequency check is four times a day. Whenever new application versions are published, they soon become available and propagate to all end-user systems. Normally, the process is transparent and seamless, but there could be exceptions. For instance, if you have an app open and running, an update could be disruptive in the middle of your work. Some developers have asked for an option to inhibit refreshes of snaps while they are running, and this is now a new, experimental feature that you can enable and test on your system. [...] The app refresh capability offers snaps users another level of control in the overall user experience. Automatic updates are geared toward security, but users can defer updates for up to 60 days, and now, they also have the ability to gracefully update applications with minimal disruption to their normal usage patterns and workflows. We very much welcome your feedback and suggestions, especially with new and upcoming features. The refresh awareness option is a good example of where the developer feedback has been valuable and useful in making the snap ecosystem even friendlier and more robust. If you have any ideas on this topic – or any other, please join our forum for a discussion.

  • How Domotz streamlined provisioning of IoT devices

    Learn how Ubuntu Core and snaps gives Domotz a competitive advantage As the number of IoT devices scale, the challenges of provisioning and keeping them up to date in the field increases. Domotz, who manufacture an all-in-one, network monitoring and management device for enterprise IoT networks, found themselves with this challenge that was further compounded by their rapid software release cadence. One of the most crucial and difficult aspects for Domotz to solve was the delivery of automatic updates to the tens of thousands of devices deployed. Domotz turned to snaps and Ubuntu Core to meet their exacting requirements. I absolutely believe that Ubuntu Core and snaps give us a competitive advantage. We are the only company in the IoT network management space that can guarantee a secure, always-up-to-date device for our customers’ on-premises deployments.

  • Zip Files: History, Explanation and Implementation

    I have been curious about data compression and the Zip file format in particular for a long time. At some point I decided to address that by learning how it works and writing my own Zip program. The implementation turned into an exciting programming exercise; there is great pleasure to be had from creating a well oiled machine that takes data apart, jumbles its bits into a more efficient representation, and puts it all back together again. Hopefully it is interesting to read about too.

    This article explains how the Zip file format and its compression scheme work in great detail: LZ77 compression, Huffman coding, Deflate and all. It tells some of the history, and provides a reasonably efficient example implementation written from scratch in C. The source code is available in hwzip-1.0.zip.

    I am very grateful to Ange Albertini, Gynvael Coldwind, Fabian Giesen, Jonas Skeppstedt (web), Primiano Tucci, and Nico Weber who provided valuable feedback on draft versions of this material.

Netrunner Linux Still Goes Its Own Way at 'Twenty'

The Netrunner distro used to be a bleeding-edge choice among KDE options. With little that's new and must-have, this release takes the edge off the bleeding. I wasn't nudged away from my preferred competing KDE distro -- the new Feren OS Plasma edition. While Netrunner 20.01 provides a fairly solid integration of classic KDE desktop performance, this release is a departure, in that it is not a step or two ahead of most other KDE-integrated Linux OSes. I Netrunner attracts two types of typical users. One fancies a more friendly desktop environment. The second wants the freedom to tweak more extensively than other desktop environments allow. Hardware requirements include a minimum CPU of 1.6 GHz Intel Atom N270 or greater and at least 1 GB of RAM with at least 10 GB hard drive space. Also, the computer should have Intel GMA 945 graphics card support with 128+ MB of video memory. Netrunner is a unique distro with its own spin on the K Plasma desktop environment. Seasoned Linux users who like to fiddle and tweak an OS into their own platform will love how this distro integrates the KDE Plasma desktop. Newcomers can be quite content using the out-of-the-box settings. Read more
