  • Introducing PodTopologySpread

    Managing Pods distribution across a cluster is hard. The well-known Kubernetes features for Pod affinity and anti-affinity, allow some control of Pod placement in different topologies. However, these features only resolve part of Pods distribution use cases: either place unlimited Pods to a single topology, or disallow two Pods to co-locate in the same topology. In between these two extreme cases, there is a common need to distribute the Pods evenly across the topologies, so as to achieve better cluster utilization and high availability of applications.

  • HamBSD Development Log 2020-05-05

    I worked on HamBSD today, still looking at improvements to aprsisd(8). My focus today was on converting AX.25 packets to the TNC2 format used by APRS-IS.

    I fixed the path formatting to include the asterisks for used path entries. Before packets would always appear to APRS-IS to have been heard directly, which gave some impressive range statistics for packets that had in fact been through one or two digipeaters.

    A little more filtering is now implemented for packets. The control field and PID are verified to ensure the packets are APRS packets.

    The entire path for AX.25 packet read from axtap(4) interface to TNC2 formatted string going out the TCP/TLS connection has bounds checks, with almost all string functions replaced with the mem* equivalents.

  • Highlights of YaST Development Sprint 98

    It’s time for another report from the YaST trenches. This time, apart from this blog post, we have several other reads for you in case you are interested on YaST development or on Linux technical details in general.


    Something we know for sure is that AutoYaST is critical for many users of SUSE Linux Enterprise and openSUSE. And, to be honest, our venerable unattended installer is showing its age. That’s why AutoYaST has a priority place in the mid-term goals of the YaST Team. The plan is to have an improved AutoYaST for SLE 15 SP3 and openSUSE Leap 15.3, although some fixes could be backported to SP2 and 15.2 if they are important enough.

    During this sprint, we started gathering some feedback from our users and colleagues at SUSE. Additionally, we did some research about the current status of AutoYaST in order to identify those areas that are in need of more love. We have put all the conclusions together as a separate blog post. Check it if you are interested in what the future will bring for AutoYaST.

    Now that we have started a new development sprint, there is an ongoing discussion that might be interesting for you about AutoYaST tooling. Please, check yast-devel, opensuse-autoinstall, or the opensuse-factory mailing lists and do not hesitate to participate. We would love to hear from you.

  • Linux AArch64 SDK

    BitFlow has released a Linux AArch64 (64-bit ARM) SDK that enables seamless integration of BitFlow frame grabbers with the NVIDIA Jetson AGX Xavier Development Kit.

    Donal Waide, Director of Sales for BitFlow, states, "Many of our customers are already using GPU solutions such as NVIDIA for image processing so adding this option to the already large BitFlow suite of adapters was a natural progression for the company. BitFlow has been supporting Linux for several years across a variety of flavors."

    Added Waide, "BitFlow was one of the first frame grabber companies to support NVIDIA's GPUDirect for Video technology. BitFlow and NVIDIA have worked together for a number of years already."

  • Top 3 benefits of Apache Cassandra and how to use it

    It’s no secret that organisations have a love-hate relationship with data. Decision making can be unguided and market insights can be lost when organisations collect too little data. On the other hand, with large and active datasets, where requests number in the hundreds of thousands, maintaining database performance is increasingly difficult.

    One open source application, Apache Cassandra, enables organisations to process large volumes of fast moving data in a reliable and scalable way. That’s why companies like Facebook, Instagram and Netflix use Apache Cassandra for mission-critical features. Let’s look at three major benefits, challenges and use cases of Apache Cassandra, and the easiest way to get it running in production.

  • Daniel Stenberg: HTTP/3 in curl
  • Gmail and Outlook sitting in a tree, not t-a-l-k-i-n-g to me or thee

    Nobody likes Mondays, least of all Google's Gmail, the POP3 and IMAP services of which fell over this morning to deprive Monday morning mailers their start-of-week fix.

    The issues appeared to kick off at around 11:30 BST and continues to prevent those who prefer to access their Googly mail via means other than the browser. The problem appears to be related to POP3 and IMAP access; if you're connecting to Google's servers using those services, then sending and receiving email could be a challenge.

    Google had planned to turn off access to G Suite account data for apps not using OAuth for first-time users from 15 June 2020 and all accounts from 15 February 2021, but back-pedalled in March, putting the move on hold "until further notice."

  • Jonathan Dowland: Amiga floppy recovery project: what next?

    It's been a while since I've reported on my Amiga floppy recovery project. With my bulky Philips CRT attached I slowly ground through the process of importing all my floppy disks, which is now done. The majority of disks were imported without errors. Commercial disks were the most likely to fail to import. Possibly I'd have more success with them if I used a different copying technique than X-COPY's default, but my focus was not on the commercial disks.

    I have not yet restored the use of my LCD TV with the Amiga. I was waiting to hear back from Amiga Kit about an agreed return, but despite their web store claiming they're still open for business, I haven't been able to get any response to my emails to them since mid-February. I've given up, written off that order and bought an RGB/SCART adaptor elsewhere instead. Meanwhile my bulky CRT has returned to the loft.

  • Play Epic Store Games With Legendary

The author, derrod, modestly acknowledged he needed Linux testers, but so far it’s been pretty easy to use and I haven’t encountered a hitch yet. It uses a text-based interface; the developer’s goal is to eventually incorporate a graphical user interface.

  • arm64 on

    The repository has been extended to cover the arm64 architecture.

    We had occasionally received user request to add "arm" in the past, but it was never really clear which kind of "arm" made sense to target for PostgreSQL. In terms of Debian architectures, there's (at least) armel, armhf, and arm64. Furthermore, Raspberry Pis are very popular (and indeed what most users seems to were asking about), but the raspbian "armhf" port is incompatible with the Debian "armhf" port.

    Now that most hardware has moved to 64-bit, it was becoming clear that "arm64" was the way to go. Amit Khandekar made it happen that HUAWEI Cloud Services donated a arm64 build host with enough resources to build the arm64 packages at the same speed as the existing amd64, i386, and ppc64el architectures. A few days later, all the build jobs were done, including passing all test-suites. Very few arm-specific issues were encountered which makes me confident that arm64 is a solid architecture to run PostgreSQL on.

And that seems to be holding pretty true in a career as an anesthesiologist as well,” he said.

  • Hot On The Heels Of Mellanox, Nvidia Snaps Up Cumulus Networks

    Last week, when we talked to Nvidia co-founder and chief executive officer, Jensen Huang, about how the datacenter was becoming the unit of compute and in such a world networking was critical, it was obvious that acquiring Mellanox Technologies for $6.9 billion was just the beginning of the strategy that will no doubt unfold in the coming months and years.

    Huang didn’t wait long to make another move, with Nvidia acquiring open network software provider Cumulus Networks for an undisclosed sum and marrying it with Mellanox in its newly formed networking business unit.

    Sometimes, to understand what a company is doing you have to take a really hard look at the things that key people at that company have seen and done in their careers. This is one of those cases.

  • What's New In Open Source With The Latest TRs

    New technology is exciting. And when it can help you run your business more profitably or efficiently, well, it becomes very exciting. With IBM i, the open source community is arguably the biggest contributor of new technology to the platform. IT Jungle recently checked in Jesse Gorzinski, the IBM i open source architect, to hear how the open source story has improved with the recent technology refreshes.

    Arguably the biggest open source-related enhancement with IBM i 7.4 TR2 and 7.3 TR8 revolves around a change in RPM, the new delivery method that IBM adopted two years ago to distribute new and updated open source libraries to IBM i users.

    Up until now, IBM i shops had to connect their IBM i server to the Internet to access the RPM repository that contains IBM i distributions of open source software, such as Node.js, Python, and PHP. But thanks to the new support for SSH tunneling in this month’s unveiling of 7.4 TR2 and 7.3 TR8, customers can now shuttle the open source libraries from an adjacent PC workstation running ACS, eliminating the need to expose the IBM i server to the Internet.

    Valve has published their Steam Survey results for April, which is the first full month where the US and still much of the world has been in lockdown over the coronavirus, and thus interesting to see how it has impacted the gamer metrics.

    The Steam Survey results for April 2020 put the Linux gaming marketshare at 0.89%, or a 0.02% increase over the month prior. While still sub-1%, the Linux gaming marketshare is consistently hitting in this 0.8~0.9% area even while Valve is reporting record number of users. The Steam Linux percentage at 0.89% for April is while macOS increased by 0.25% to 4.05% and then the Windows percentage pulled back 0.27% to 95.06%.

  • Champions Of Regnum On PCLinuxOS

    Champions of Regnum (Regnum online previously) is a multiplayer 3D medieval fantasy online RPG video game, produced in Argentina by NGD Studios (currently NGE), for free to anyone, with the option to pay for premium content.

    It is available in Spanish, Portuguese, German, English and French. The game has 3 servers and an experimental one (for testing), which are "Ra" (international server) "Haven" (international server, mainly in English) "Valhalla" (Germany) and the experimental "Amon". The word "Regnum" comes from Latin and means kingdom.

    The game focuses on the conflict between three kingdoms, with gameplay revolving around realm versus realm combat. Players fight in groups against players from opposing factions and capture forts and castles. In addition, the usual character development, typical in other games of the genre, is present, as well as battles between players and monsters.

  • March and April in KDE PIM

    Following the post about what happened in KDE PIM in January and February let’s look into what the KDE PIM community has been up to in March and April. In total 38 contributors have made almost 1700 changes. Big thanks to everyone who helped us make Kontact better!


    The Google Calendar and Google Contacts backends have been merged into a single Google Groupware resource (Igor Poboiko, D28560). The change should be mostly transparent to users, the old backends will be migrated to the new unified backend automatically after update. During this Igor also fixed various bugs and issues in the backends and the LibKGAPI library, big kudos to him!

    The DAV resource is now able to synchronize the calendar color from KOrganizer to the DAV server (David Faure, D28938). Related to that, the menu to configure calendar color in KOrganizer has been simplified by removing the “Disable Color” action.

    It is now easier to recognize and set the default calendar and the event editor now respects the settings correctly.

  • $50 Open-Source Colorimeter is Remarkable in Comparison to Commercial Models

    Researchers from Michigan Technological University are applying chemistry to 3D printing, detailing their recent study in ‘Open-Source Colorimeter.’ A basic sensor, the colorimeter is made up of a simple light source. Light is controlled and transmitted, filtered so that only a slight band near the absorbance peak is allowed.

    While the general public may not be aware of or use these types of sensors commonly, they are often used in major applications with food (bread, chocolate, and milk), along with monitoring nitrates, metal, phosphates and materials present due to commercial production like that of paper or other goods. Colorimeters are used in medical applications too for measuring protozoa in lab cultures, measuring UV radiation through skin color transformation, and even for studying the age of bruises. Colorimeters may also be used for evaluating waste waters and water quality.

  • ReactOS: Dipping A Toe In A Millennium-era Open Source Dream

    Do you remember when trying a new OS meant burning a CD? Not merely downloading an ISO and mounting it on a USB drive, but taking a circle of polycarbonate and hoping you didn’t get a buffer underrun as the file you’d spent an entire day downloading was burned onto it. A couple of decades ago that was how we’d take a look at a new Linux distro, and at the time we considered it to be nothing short of incredible that such a thing was possible. One of the ISOs I remember downloading back then was an early version of ReactOS, a project with the lofty aim of creating an open-source equivalent of Windows NT. You might think that in the nearly two decades since then it would have become an irrelevance and its contributors moved on to other work, but no. ReactOS is very much still with us, and indeed has just seen a new release. Version 0.4.13 is the latest in a long line of incremental updates, and remembering those early ReactOS ISOs when I saw their announcement, I thought I’d give it a spin. The result was both a peek at the current state of the project, and a chance to think about the place of a Windows clone in 2020.

  • Open source NodeTube allows users to beat censorship and deploy their own YouTube alternative

    Discontent is running high among an increasing number of YouTube creators and users these days, due to a seemingly never-ending series of questionable policies and decisions this Google company has been making. But the pull of the gargantuan platform that has both the audience and the money is proving too powerful to allow much meaningful competition.

    That is, at least in YouTube’s own category, as a centralized corporation built in obscurity, i.e., as a closed-source app.

    This is why much of the effort to provide alternatives to YouTube and other dominant social networks is today focused on decentralization and open source as a value proposition for those creators and users eager to protect their ever-more at risk privacy and free speech.

  • Point of WebGPU on native

    WebGPU is a new graphics and compute API designed on the grounds of W3C organization (mostly) by the browser vendors. It’s designed for the Web, used by JavaScript and WASM applications, and driven by the shared principles of Web APIs. It doesn’t have to be only for the Web though. In this post, I want to share the vision of why WebGPU on native platforms is important to me. This is highly subjective and doesn’t represent any organization I’m in.


    The story of WebGPU-native is as old as the API itself. The initial hearings at Khronos had the same story heard at both the exploration “3D portability” meeting, and the “WebGL Next” one, told by the very same people. These meetings had similar goals: find a good portable intersection of the native APIs, which by that time (2016) clearly started diverging and isolating in their own ecosystems. The differences were philosophical: the Web prioritized security and portability, while the native wanted more performance. This split manifested in creation of two real working groups: one in W3C building the Web API, and another - “Vulkan Portability” technical subgroup in Khronos. Today, I’m the only person (“ambassador”) who is active in both groups, simply because we implement both of these APIs on top of gfx-rs.

    Kotlin shares several attributes with Java and was designed to streamline Android app development. Apple's Swift, on the other hand, was designed to interface with C-based code and libraries, providing an open source approach for iOS and OS X app development. However, both languages boast the ability to delve into both the world of Android and iOS, leaving many developers at a crossroads where they must choose one language over the other.

  • Staying "Safe" While You Stream: DBD's Tips On Living DRM-Free During Quarantine

    As most of us are cooped up in our homes due to the ongoing COVID-19 pandemic, it's somewhat natural that we turn to online movies, music, and other media to help pass the time. For most people, this involves turning to Internet streaming for convenient, "all-in-one" services that promise an endless array of recommendations to while away the hours. "Binging" is all well and good every once in a while, but we should remain careful that the ways we're getting our media don't come with compromises to our freedom. As we've mentioned before, Netflix and other giant media providers are responsible for keeping the practice of DRM (Digital Restrictions Management) alive, and it's important not to provide them with the subscription fees they need to keep going. It's also important, even under less dire circumstances, to support businesses and websites that provide DRM-free media, and to promote them to our friends. So to help provide you with a plethora of DRM-free and often gratis places to stream from while keeping your rights, here's a few choice selections from our Guide to DRM-free Living.


    Time under quarantine is also the perfect opportunity to learn about new topics -- even the fight against DRM itself! The [LibrePlanet video library][17] is an excellent place to find talks covering issues relating to the Defective by Design campaign, such as Cory Doctorow's keynote presentation on the "software you can go to jail for talking about", this 2019 session from the Library Freedom Institute, and a talk given on the Right to Repair movement.

  • NVIDIA Gets Into Open-Source Hardware With A Ventilator Design

    While waiting to see what NVIDIA will be doing on the open-source driver front that has been pushed back, NVIDIA made a surprise open-source announcement today.

    As a result of the COVID-19 pandemic, NVIDIA has announced a new open-source ventilator design currently awaiting emergency use authorization from the US FDA.

  • Ten Years of Open Source Hardware

    I believe that we will continue to see more and increasingly advanced board designs, both from industry and the wider open hardware community. The benefits are clear in terms of education, technology transfer, establishing plarforms and expediting innovation, for example. Not to mention enthusiast and professional engineers alike continuing to up their ‘spare time’ game.

    Meanwhile the wider community continues to grow and whether identifying as being part of the open hardware movement, a maker, an electronics hobbyist or a Raspberry Pi enthusiast, this all contributes to more people getting hands-on with electronics.

    Ten years ago it would have been impossible to predict the size of the opportunity that would be presented by free and open source silicon (FOSSi). Since digital designs generally start out with a text based hardware description that might look like, or even be based upon, a programming language, in hindsight this may now seem blatantly obvious. After all, it means that a lot of the tooling and processes from software development can be reused.

  • Redis 6.0 Released As A Big Update For This In-Memory Key-Value Database

    Redis 6.0 is out to end out April as this widely-used, open-source in-memory key-value database solution.

    Redis 6.0 brings ACL support, client-side caching support, threaded I/O, RESP3 support, SSL, improved PSYNC2 replication protocol handling, much faster RDB file loading, and many other features.

    Lead Redis developer Salvatore Sanfilippo calls version 6.0 "the biggest release of Redis *ever*", in today's release announcement.

  • Text file driven applications

    I know I talked about charm, but there are some concrete reasons why I prefer the text file driven mode for many things. The primary one is that I can focus on the fundamental content of the diagram or task instead of being distracted by font sizes, or milimeter level adjustments of components. This was true of LaTeX, and it is true of PlantUML. In most cases the tool taking in the text file as input makes some layout decisions automatically. In most cases, this is good enough, and in many cases is actually better than what I could achieve manually.

    The next advantage is that I can version control my source file and can make semantically meaningful diffs. I can’t do this with the save files of GUI programs which are often just memory dumps of RAM.

    I can copy and paste components much more easily that I can with purely GUI driven tools. I can add comments. I can comment out sections and then uncomment them later.

    Often, I can type and create a diagram faster than I can drag and draw with my mouse. If I have a live preview, I’m a whole lot more productive with text file based software than I am with GUI based software.

    What tools would YOU like to add to this list of awesome text file based applications?

  • Stressing the network when it’s already down

    It would appear that every time that Virgin Media dropped off, people en masse flocked to speedtest services to confirm that their internet connection was having problems.

    If you go down to the NetFlow level, you can even see very clearly when services were restored for customers: [...]

    This kind of collective behaviour is fascinating to me, and also presents an interesting customer driven positive feedback loop for networks that might be having temporary congestion problems, where people that are verifying that the network is congested, are themselves adding more congestion to the network.

  • virt-viewer version 9.0 released

    I am happy to announce a new bugfix release of virt-viewer 9.0 (gpg), including experimental Windows installers for Win x86 MSI (gpg) and Win x64 MSI (gpg).

    Signatures are created with key DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R)

    With this release the project has moved over to use GitLab for its hosting needs instead of Pagure. Instead of sending patches to the old mailing list, we have adopted modern best practices and now welcome contributions as merge requests, from where they undergo automated CI testing of the build. Bug reports directed towards upstream maintainers, should also be filed at the GitLab project now instead of the Red Hat Bugzilla

  • Couchbase automates cloud-native database management

    New version of open source NoSQL database vendor Couchbase's Autonomous Operator brings more management to cluster administrators.

  • Top Docker best practices for container management

    Containerization in and of itself offers various benefits, such as reduced overhead, improved portability and better application development. Docker helps increase the advantages of containers while also providing repeatable development, build, test and production systems.

    To ensure successful Docker deployments, admins should implement several Docker best practices that include the use of Dockerfile commands, container backup procedures, Nginx load balancer basics and cloud container deployments.


    Without proper management techniques, admins risk complicating their container deployments. If backups are not correctly handled, admins risk misplaced restorations and incompatible components. There are a few container backup best practices that admins can use to ensure their Docker containers remain organized and available.

  • openSUSE Tumbleweed – Review of the week 2020/18

    This week, we released a few snapshots less. But we released GNOME 3.36.1 which also contained a minor font change for cantarell. And as openQA compares reference screen shots, a font change results in a lot of mismatches, that need to be confirmed. This takes easily a bit of time. This resulted in three snapshots being published (0425, 0427 and 0428), bringing those changes:

    GNOME 3.36.1
    KDE Applications 20.04
    Linux kernel 5.6.6
    Mesa 20.0.5
    openSSL 1.1.1g
    The list looks short, but GNOME and KDE Applications both consist of numerous applications. So all in all the snapshots were actually rather large.

  • A guide to open source software for procurement professionals

    The first and most important step in negotiating any agreement is always to get the facts. For example, when negotiating a software development agreement, the developers for both parties probably assume that the software will include many pre-existing components written by third parties. If the procurement and legal personnel negotiating the agreement assume that there should be no code that is not written by the vendor, the process will be inefficient and waste a lot of everyone’s valuable time.

    If developers are confronted with ridiculous assumptions about writing software from scratch, the credibility of the procurement process is undermined, and, in the future, they will find ways to avoid or delay involving procurement and their legal counsel.

    The Linux Foundation recently published a whitepaper written by Karen Copenhaver and Steve Winslow that aims to help procurement professionals and their legal counsel avoid making erroneous factual assumptions that will undermine their credibility and delay negotiations through a better understanding of software development and the use of open source software assets. This is a summary of its findings.


    A common perception of the GPL and its variants as being unworkable open source licenses is inaccurate. Keep in mind that the GPL, like all free and open source licenses, does not restrict your usage. As a recipient of GPL software, you have far more expansive license rights to use the software than you have under a proprietary software license agreement. Compliance with the GPL upon a redistribution of the code may be a factor to consider but should be compared with the fact that you would likely not have the right to redistribute proprietary software at all.

    A company can have a “no GPL policy,” yet it cannot operate in most industries without dependence upon the Linux operating system, which is GPL-licensed software.

    Unless your technical people agree that there should be no GPL or copyleft licensed code of any kind used in its development or provided in the work product, do not ask for a representation or warranty that there will be no copyleft software. Once again, the relevant questions related to the selection of the code, maintenance of the code, and compliance with the applicable license terms in the relevant use case.

  • Riccardo Padovani: Introducing an opensource alternative implementation of the AWS console. [Ed: This won't sole the problem of AWS itself being a proprietary software surveillance trap] is a website to manage some of your AWS resources: since this is an early preview, at the moment, it supports a subset of Networking, EC2, SQS, and SNS

    The AWS Console is an amazing piece of software: it has hundreds of thousands of features, it is reliable, and it is the front end of an incredible world. However, as any software, it is not perfect: sometimes is a bit slow, so many features can be confusing, and it is clear it has evolved over time, so there are a lot of different styles, and if it would be made from scratch today, some choices would probably be different.

Linux on the OneGx1 mini laptop: Running Ubuntu 20.04

The One Netbook OneGx1 mini laptop is an unusual little computer that features a 7 inch display, an Intel Core i5-10210Y quad-core processor, and a physical design clearly inspired by gaming laptops. It supports an optional set of detachable game controllers that can clip onto the sides of the device. And One Netbook offers the OneGx1 with optional support for 4G LTE or 5G cellular networks. As I discovered after spending a few days testing the OneGx1, it offers decent performance for general purpose computing, but gaming is a bit of a mixed bag. But that was with Windows 10.

  • Introducing modulemd-tools

    A lot of teams are involved in the development of Fedora Modularity and vastly more people are affected by it as packagers and end-users. It is obvious, that each group has its own priorities, use-cases and therefore different opinions on what is good or bad about the current state of the project. Personally, I was privileged (or maybe doomed) to represent yet another, often forgotten, group of users - third-party build systems. Our team is directly responsible for the development and maintenance of Copr and a few years ago we decided to support building modules alongside building just regular packages. We stumbled upon many frustrating pitfalls that I don’t want to discuss right now but the major one was definitely not enough tools for working with modules. That was understandable in the early stages of the development process but it has been years and we still don’t have the right tools for building modules on our own, without relying on the Fedora infrastructure. You may recall me expressing the need for them at the Flock 2019 conference.

  • GSoC 2020 nmstate project update for June

    This blog is about my experience working in nmstate project and first month in GSoC coding period. I was able to start working on implementing the varlink support mid of community bonding period. This was very helpful because I was able to identify some issues in the python varlink package that was not mentioned in documentation and I had to spend more time finding the cause of the issue. There have been minor changes to proposed code structure and project timeline after the feedback from the community members. In the beginning it was difficult to identify syntax errors in varlink interface definitions. This has been slow progress because of new issues and following are the tasks I have completed so far.
