Solaar | Application for Logitech Unifying Receivers and Devices on openSUSE

Filed under
Software
SUSE

I recently purchased a new Logitech wireless keyboard for my kitchen computer because the Bluetooth keyboard I previously used was driving me nuts. Mostly for the keyboard layout and sometimes because it didn’t want to connect. Possibly due to hardware failure or bad design. It also doesn’t have media keys so I thought it best just to replace it.

I have previously used ltunify with success but I only used it because “L” comes before “S” so that was my first stop. Since I received feedback that I should try Solaar I did so this time. Since there isn’t an official Linux based application available from Logitech, the fine open source community has stepped in to make managing your devices simple and straight forward.

[...]

Having Solaar in the system try is quite handy. Though, the reality is, I don’t need it all the time but having it to manage your devices is very handy. It’s nice to know that you can manage multiple Unifying receivers with this application. This is easy to use and has a great, well laid out and straight forward interface. I am glad I was recommended to try this application out.

SUSE
Ubuntu

Among all the Linux distros out there, openSUSE and Ubuntu are two of the bests. Both of them are free and open-source, leveraging the best features Linux has to offer. However, each has its spice.

In this article, we’ll be having a look at a detailed comparison between openSUSE and Ubuntu. The goal isn’t to declare which one is better than the other. That’s up to the user to decide. Instead, let me shed light on points you should consider when choosing between Ubuntu and openSUSE.

Let’s get started!

  • IBM Research open-sources SysFlow to tackle cloud threats

    IBM Corp.’s research division today announced the release of SysFlow, an open-source security toolkit for hunting breaches in cloud and container environments.

    SysFlow is designed to tackle a common problem in network protection. Modern security monitoring tools capture system activity with a high degree of granularity, often down to individual events such file changes.

    That’s useful to a point but also creates a large amount of noise that makes spotting threats harder. IBM researchers Frederico Araujo and Teryl Taylor described looking for breaches under such circumstances as “akin to searching for a needle in an extremely large haystack.”

  • Red Hat DevSecOps Strategy Centers on Quay

    Red Hat is moving toward putting the open source Quay container registry at the center of its DevSecOps strategy for securing containers.

    The latest 3.2 version of Quay adds support for Container Security Operator, which integrates Quay’s image vulnerability scanning capabilities with Kubernetes. Dirk Herrmann, senior principal product manager for Red Hat, says that capability will make it possible to leverage the open source Clair vulnerability scanning tool developed by CoreOS. Red Hat acquired CoreOS in 2018.

    [...]

    The latest release of Quay also makes it easier to extend DevSecOps processes across multiple instances of the container registry. Version 3.2 of Quay includes a mirroring capability that makes it possible to replicate instances of Quay container registries across multiple locations. In fact, Herrmann says one of the things that differentiates Quay most from other container registries is its ability to scale.

    Other capabilities added to Quay include support for OpenShift Container Storage 4, which is enabled via NooBaa Operator for data management, based on the S3 application programming interface (API) for cloud storage developed by Amazon Web Services (AWS).

  • 2020 Red Hat Women in Open Source Award Nominations Now Open

  • Melissa Di Donato, CEO, SUSE: On cloud journeys, hyperscaler complexity, and daring to be different

    When Melissa Di Donato joined SAP in 2017, having counted Salesforce, IBM and Oracle among her previous employers, she told this publication it was like ‘coming home.’ Now, as chief executive of Linux enterprise software provider SUSE, it is more a step into the unknown.

    Yet it is not a complete step. Working with a proprietary software company means your experience is primarily in selling it, implementing it and aligning it to others’ business needs. With SUSE, Di Donato knows far more acutely what customers want.

    [...]

    Not unlike other organisations, SUSE’s customer base is split into various buckets. You have traditionalists, which comprise about 80% of customers, hybrid beginners, cloud adopters and cloud-native; the latter three all moving in ever decreasing circles. Regardless of where you are in your cloud journey, SUSE argues, the journey itself is the same. You have to simplify, before you modernise, and then accelerate.

    Di Donato argues that cloud and containers are ‘very, very overused words’, and that getting to grips with the technology which holds the containers is key – but all journey paths are valid. “Whether cloud means modernising, or container means modernising, VMs, open source… [customers’] version of modernising is really important, and they want to simply and modernise to then get to a point where they can accelerate,” she says. “Regardless of what persona you are, what customer type you are, everyone wants to accelerate.”

    These days, pretty much everyone is on one of the hyperscale cloud providers as well. SUSE has healthy relationships with all the major clouds – including AWS, which is a shot in the arm for its occasionally-criticised stance on open source – aiming to offer partnerships and value-adds aplenty.

AppImageLauncher | AppImage Manager on openSUSE

Reviews
SUSE

Right of the cuff, I should note that this will work on other Linux distros too, I am just focusing on openSUSE because, that is my jam. I have been using this on openSUSE Tumbleweed as of Snapshot 20200103. It should also work on Leap as of 42 and newer (that means Leap 15.x is good to go, in case there was any question).

The reason this application excites me so is that I use several AppImages on my system. Which ones you may ask? I’ll tell you, xLights, which I use for my Christmas Light display, VirtScreen that I use when I am remote and need to turn my laptop or phone into a second display. This is super handy as it will not only create links in my menu to the AppImages, it will also copy the *.AppImage file into a designated folder, in my case ~/Applicaitons which is the default. At first, I wasn’t sure about it but after noodling it around a bit, I am totally good with it.

Red Hat and SUSE Leftovers

Filed under

SUSE
  • Debugging applications within Red Hat OpenShift containers

    There are debugging tools that can be used within containers but are not preinstalled in container base images. Tools such as strace or Valgrind must be included in a container during the container image build process.

    In order to add a debugging tool to a container, the container image build process must be configured to perform additional package installation commands. Whether or not package installation is permitted during the image build process depends on the method being used to build the container image. OpenShift provides several methods of building container images. These methods are called build strategies. Currently, OpenShift supports the Dockerfile, Source-to-Image (S2I), Pipeline, and Custom build strategies. Not all build strategies allow package installation: Of the most commonly-used strategies, the Dockerfile strategy permits package installation but the S2I strategy does not, because an S2I build process builds the container image in an unprivileged environment. A build process within an unprivileged environment lacks the ability to invoke package installation commands.

  • Fedora 33 To Finally Kill Off Python 2.6 Support

    Python 2.6 has been end-of-life all the way back to late 2013. However, Python 2.6 packaging for Fedora has kept upt in order to maintain some compatibility with RHEL/EPEL 6 having Python 2.6. But now with EPEL 6 reaching end-of-life as the extra packages for Red Hat Enterprise Linux 6 / CentOS 6, Fedora will gut its Python 2.6 support should anyone still be using it outside of the EPEL building/testing use-case. EPEL 6 is being retired in November 2020, similar to the expected release of Fedora 33.

  • Transformation – Simplify First

    While a bit of a stretch, there is some similarity to the dilemma that many companies are facing in this rapidly changing business environment. In my last blog, I talked about how companies are looking at the digital transformation of their business in order to stay competitive in a rapidly changing world. In a 2019 report by 451 Research commissioned by SUSE, 89% of survey respondents are considering, evaluating or executing their digital transformation strategy.

Kdenlive 19.12 on openSUSE | Review

SUSE

Making videos is not exactly my strong suit but it doesn’t have to be to enjoy it. Lately, I have been dipping my toes into the world of video content creation. Yes, most of it is into making videos as I haven’t really had the need. Recently, a need popped up for doing some video editing and I decided to give Kdenlive a try. You have to start somewhere and since many of the independently created shows out there use it, it is part of the KDE project and there are a LOT of tutorials on YouTube.

Keep in mind, I have some very basic needs, simply, chaining clips together, title screen and a little background music. These are extremely minimal requirements. The nice thing about Kdenlive is, it is easy enough to get going with it, but brimming with features to keep you dinking around with it continually and even if you have come to learn every feature the Kdenlive Project will come along and bring you an update.

[...]

Kdenlive is a great application with a lot more features than I know how to even use. I don’t do any complex video editing. I don’t have good video equipment so I don’t have a real high level of motivation to create a lot of video content at this time. You can only polish a turd so much and I am often not happy with the video I shoot. I am happy, however, with what I can do with the video in Kdenlive. It does make turning the lack-luster video into barely acceptable video content. Editing with Kdenlive is easy to use and is enjoyable to turn the mess I start with into something more usable. I would like to make more excuses to do more video content because the great user experience Kdenlive provides.

I have heard of people complain that Kdenlive isn’t stable, well, that is a bunch of hooey. Kdenlive on openSUSE Tumbleweed works fantastically well without any crashing. I am very thankful for fantastic packaging and QA process from the openSUSE Project and I am very grateful for every programmer that has had a hand in every piece of this, from the Linux kernel to the Plasma desktop to the application itself. Thank you for all your time and efforts.

Tumbleweed Provides Some Stability to 2020

Filed under
SUSE

The year of 2020, at least in the openSUSE world, is starting out to be pretty stable. In little more than a week into the new year, there have been five openSUSE Tumbleweed snapshots released.

The releases, with the exception of one, are either posting a stable rating or are trending at a stable rating, according to the Tumbleweed snapshot reviewer.

With the release of snapshot 20200107, more OpenGL and Vulkan driver features and improvements came in the update of the Mesa 19.3.1 package. The newer version update also provides better AMD Radeon Accelerated Processing Unit (APU) performance.

The bluez-tools package that is a set of tools to manage Bluetooth devices for Linux had a minor update from the previous three-year-old package included in Tumbleweed. GNOME’s web browser package epiphany provided some security AdBlocker preferences in the 3.34.3.1 version. Message transfer agent exim reduced the start up process initialization with version 4.93.0.4 and fixed more than a half dozen bugs. KDE’s kdevelop5 5.4.6 version fixed some wrong text in the license. Network detector, packet sniffer, and intrusion detection system package for wireless network kismet updated to its December release in the snapshot. One package update that stands out in the snapshot is the release of the finger reader package for Linux devices libfprint 1.0; this first major release provides better documentation and bug fixes related to restarting a failed verification immediately.The osc 0.167.2 package fixed regression in osc chroot. Other packages updated in the snapshot were rubygem-parser 2.7.0.1 and tigervnc 1.10.0 among others.

Emby Media Server on openSUSE Linux | Review

Filed under
Reviews
SUSE

One of the main reasons I build a computer was for the purposes of hosting my video content on my system and serve it to other machines. I had heard about having something like Netflix or Hulu in the form of Plex. I have known others that have done this and have always been impressed by it. My first stop in exploring media servers in Linux was Emby. I chose it largely because I heard of Plex and wanted to try something that was open source based, more on that later. At the very beginning of this exercise, I decided I want to try out three different server products, Plex, Emby and Jellyfin.

This is my review, with no real expectations, other than to easily have access to my movies and TV shows from any device in the house. This is a review of only the free services, not the paid features. Bottom line up front. I like it and it has few issues.

  • Q&A: What it is like to be on the openSUSE Board

    You already know what a fantastic platform openSUSE is for doing just about anything with Linux. So what’s behind that easy-to-use and super powerful distribution that we know and love, and have come to rely on. In many minds there is a perception that its simply SUSE with the proprietary code stripped out. It’s true that a lot of the development work does flow down from SUSE but there is also an active community of dedicated volunteers who drive and make the project work, adding the goodies we have come to take for granted for the myriad of uses we have come to rely on it for.

    It’s election time at openSUSE and the election board asked an existing board member Gertjan who has agreed to step up again and run for re-election of what it is like to be on the board. Below is a transcript of an offline interview between fellow election committee member Edwin and Gertjan highlighting what it’s like to be on the board of openSUSE.

    Edwin: Would you like to tell us about your daily schedule and how does being an openSUSE Board member impacts on that?

    Gertjan: To be fair, my daily schedule varies a lot, depending on what is on my table. Most of the time this leaves me with enough spare time to do board related things. But before I was on board, I spent that time in openSUSE too, i.e. forums, IRC etc., so the main impact on my daily schedule were the bi-weekly video conference calls. For the rest I just spread the spare time a bit differently. It does take a couple of hours though, on an average week.

    Edwin: Do you still remember what motivated you to step up for Board candidacy the first time? And then why a second time?

  • Etherpad updated (again)

    As you might have noticed on our status page, our etherpad instance at https://etherpad.opensuse.org/ was updated to the latest version 3 days ago.

    But this time,we did not only upgrade the package (which lives, btw, in our openSUSE:infrastructure project), we also migrated the underlying database.

    As often, the initial deployment was done with a "just for testing" mindset by someone, who afterward left his little project. And - also as often - these kind of deployments suddenly became productive. This means - in turn - that our openSUSE heroes team suddenly gets tickets for services we originally did neither set up, nor maintain.

  • Nathan Wolf: Building an AMD Server and Game Machine out of Yester-Year's Parts

    Operating System | openSUSE Tumbleweed

    There really wasn’t any other choice. I need long term reliability and I am not interested in reinstalling the operating system. I know, through personal experience, that Tumbleweed works well with server applications, is very tolerant to delayed updates and will just keep chugging away.

    [...]

    This was an area that took me several months of research and reading. My criteria was that I had to have Storage Array BTRFS Raid 10. This afforded me a lot of redundancy but also a lot of flexibility. This will allow me to slowly upgrade my dries capacity as they begin to fail.

    When deciding the file system, I did a lot of research into my options. I talked to a lot of people. ZFS lost consideration due to the lack of support in Linux. I am perfectly aware that the development is done primarily within Linux now but it is not part of the mainline kernel and I do not want to risk the module breaking when the kernel updates. So, that was a non-starter.

    [...]

    Although this computer has only been up and running for about two months, I am slowly adding more services and functions to it. For now, it is pretty light, but in a few short months, that will most certainly start growing. I am very happy happy with the sub-$700 build for a computer system that has met or exceeded my expectations. It was a fun first complete, from ground up, scrap-together assembly that really was a gamble. I am pleased with how well openSUSE Tumbleweed runs on it and that I have had no disturbances with any operating system updates.

    Often, after a project, you will review it, have an “After Action Review” and ask yourself, “What would I do differently if I were doing this again.” I can honestly say, there is nothing I would change. I like everything about this machine. I would, perhaps, like more storage space as I have already gobbled up 2.5 TiB of my 5.5 TiB of storage space. Reviewing what I spent and the additional cost of the larger storage, I would have still made the same decision. So, back to would I change anything? No, I think I made the right decision. I do have upgrades planned for the future but that is a project for the fall. This machine truly fits my needs, even if much of the hardware is yester-years retired bits.
