Xfce 4.14 Coming Soon

Filed under
GNU
Linux
  • Xfce 4.14pre1 released!

    Note: A lot has happened since Xfce 4.12 was released four years ago and this announcement only covers the changes that were included in the latest development releases dubbed as Xfce 4.14pre1. Also, we have noticed some confusion by people or news outlets that seem to mistake xfdesktop for the “Xfce Desktop Environment”.

    The comprehensive changelog will be provided with the Xfce 4.14 final release, but here go some select highlights that were released in the last week (chosen subjectively by the author).

  • Xfce 4.14 Sees Its Long-Awaited Pre-Release

    The GTK3-ported Xfce 4.14 might see its long-awaited official release in the near future. In preparing for a hopeful August debut, the Xfce 4.14 pre-release is now available.

    It's been four years since the release of Xfce 4.12 and in addition to the GTK3 tool-kit re-tooling there has been a lot of UI improvements, vblank support added, colord integration, and many other feature additions.

Review: Sabayon 19.03

Filed under
Gentoo
Reviews

Sabayon's claim that it is a "beginner-friendly" distro that is "bleeding edge" and "stable and reliable" is a bit of a stretch. I doubt "beginners" will comprehend the instructions for what to do after installing Sabayon - and that is assuming inexperienced users will find the information in the first place. Similarly, the systemd and GNOME versions are rather old for a distro that claims to be "bleeding edge". That said, I did find Sabayon's GNOME edition to be stable and reliable, bar a few minor issues (such as the notification about the VirtualBox kernel service not running).

I don't think it is entirely fair to ask if Sabayon lives up to the bold marketing slogans on its home page. Personally, I see Sabayon as a friendly and interesting distro for tinkerers and distro-hoppers, and a very good one at that. I should also mention that, in general, Sabayon's use of language is refreshingly informal; both the graphical Rigo package manager and the wiki put a smile on my face more than once. Even Equo has some jokes built in - the command equo moo prints an ASCII cow that says "Entromoooo!".

Sabayon does still has some way to go to become the sophisticated operating system it wants to be. With 19.03 the distro switched from the Anaconda to the Calamares installer which, to my mind at least, is a good decision. However, contrary to what is claimed in the release notes, the disk encryption issue has not been resolved yet and the wiki still talks about how to find your way through the Anaconda installer. Work on the new wiki announced in the release notes seems to be at a very early stage.

I also couldn't fail to notice that Sabayon's forums are rather quiet. Lively forums don't necessarily equate to a thriving community, but the overall feeling I got is that Sabayon could do with a bit more momentum. That shouldn't discourage you from giving Sabayon a try though. On the contrary, if you are a Linux-loving tinkerer then Sabayon might be the distro for you.

  • KDE Craft now delivers with vlc and libvlc on macOS

    Lacking VLC and libvlc in Craft, phonon-vlc cannot be built successfully on macOS. It caused the failed building of KDE Connect in Craft.

    As a small step of my GSoC project, I managed to build KDE Connect by removing the phonon-vlc dependency. But it’s not a good solution. I should try to fix phonon-vlc building on macOS. So during the community bonding period, to know better the community and some important tools in the Community, I tried to fix phonon-vlc.

Getting started with GNOME Boxes virtualization

Filed under
GNOME
HowTos

I've been a fan of virtualization technology for many years, using many different products along the way. Virtualization has advantages for both the data center and the desktop: data centers use it to increase server hardware utilization, while desktop users use it for modeling, testing, and development work. One operating system running on top of a different one on the same hardware, all thanks to the concept of a virtual machine (VM).

I recently upgraded my laptop from Fedora 29 Workstation Edition Linux to version 30. I noticed GNOME Boxes, simply titled Boxes, in my application menu. The GNOME Project—whose members are the creators and maintainers of the GNOME Desktop Environment—describes GNOME Boxes as: "A simple GNOME application to view, access, and manage remote and virtual systems." Of course, I had to check this tool out.

This two part series article will cover two of the main features of Boxes. While writing this article, I used Boxes version 3.32.0.2-stable. Since the GNOME Boxes project refers to a VM as a "box," I'll use that terminology.

Linux 5.2-rc1

Filed under
Linux

Nothing particularly odd going on this merge window. I had some travel
in the middle of it, but to offset that I had a new faster test-build
setup, and most of the pull requests came in early (thank you) so my
travels didn't actually end up affecting the merge window all that
much.

We did have a few late pull requests too, but since that meshed fairly
well with my schedule as per above, and people generally made the
proper noises ("sorry for late pull request, I had good reasons: xyz")
I didn't mind this time. But let's try to not repeat that, ok?

Things look fairly normal. Just about two thirds of the patch is
drivers (all over), with the bulk of the rest being arch updates,
tooling, documentation and vfs/filesystem updates, of which there were
more than usual (the unicode tables for ext4 case insensitivity do end
up being a big part of the "bulk" side).

But there's core networking, kernel and vm changes too - it's just
that the other areas tend to simply be much bulkier. Drivers etc tend
to just have a ton more lines to them, if only by virtue of there
being so many of them (although admittedly also sometimes because some
drivers tend to just be very verbose and have a lot of register
definitions etc).

  • Introducing GopenPGP, an open source encryption library for native applications

    Open source is a core principle of ProtonMail. We’re excited to make even more of our code available for independent inspection and use by the developer community.
    In 2016, ProtonMail became the maintainer of OpenPGP.js, the world’s most widely used Javascript email encryption library. Since then we have updated the library with new features, such as streaming encryption; assisted developers to adopt the library in their own applications; and submitted the library to independent security audits.

    Today, we are happy to announce another open source project that will be maintained by ProtonMail: GopenPGP. This project consists of a high-level OpenPGP library, as well as a fork of the golang crypto library. We started this project to make it easier for mobile and desktop developers to use OpenPGP encryption in their apps.

  • Seven Major Trends in the Cryptoasset Industry, According to ConsenSys

    Web 3.0 Development Will Mostly Be Open-Sourced, But “Not Free”

    As confirmed by ConsenSys, open-source projects like OpenSSL Software and also open-source blockchain and crypto-related initiatives are, for the most part, operating on relatively low budgets due to lack of adequate funding.

    Although the management at ConsenSys believes Web 3.0, an evolving set of protocols and standards for the new internet, will be created mainly through open-source development projects, it also noted that the world wide web of the future will not be developed “for free.”

    On May 11, 2019, Ethereum co-founders Vitalik Buterin and Joseph Lubin announced they had donated 1,000 ether (each) to Moloch DAO, an initiative aimed at acquiring funding for the ongoing development of Ethereum’s open-source ecosystem.

    Penn AI is designed to be used by anyone interested in AI, regardless of experience level, from high school students to trained researchers. Users can either import their own datasets for analysis within the tool or use one of the hundreds provided by UPenn.

  • Former Chef Software CTO talks IT automation, open source

    Adam Jacob: I'll eventually start another company and do something in enterprise software, because that's where my expertise is, and that's what I like. But I don't know exactly what it'll be or when.

    We have to build the system that makes people effective at adopting new technology -- whatever it is, wherever it may be in the stack -- that they need to run their business more effectively, instead of just the next platform.

    Things like serverless are interesting, because they point the way to the user experience, and they're going to get adopted and have value. Are they the future of enterprise computing? Maybe for a minute. But then, there'll be something else. And until we get good at navigating those transitions, which we're completely bad at right now, I don't know that it matters.

  • XJTLU brings Moodle - one of the world's most popular open source learning platform - event to China for first time

China MoodleMoot, part of XJTLU's 2019 Annual Conference on Higher Education Innovation, will see Dr Dougiamas share his experience in using technology to transform teaching and learning.

    Dr Dougiamas, who developed the Moodle software as part of his PhD in Australia and went on to release it to the world as an open source technology in 2002, says he is looking forward to discussing the future of Moodle in China. "Anecdotally, we know many people use Moodle in China - we hope to see many of them at the first China MoodleMoot to help plan the future of Moodle, and open technology in general, in China," he says.

  • Top Open source NoSQL database programs

    NoSql, it stands for Not Only SQL, refers to the non-relational database. The next generation database mainly addresses several key points: non-relational, distributed, open source, and horizontally scalable. The non-relational database has developed very rapidly due to its own characteristics. The NoSQL database was created to solve the challenges brought by the multiple data types of large-scale data collection, especially the big data application problem. It also supports easy replication, simple APIs, final consistency (non-ACID), and large data. It is stored by us with the most key-values, and of course other document types, column stores, graph databases, XML databases, and so on. Here are some top available NoSQL database programs in Open source or free category.

  • The Untapped Potential of Making and Makerspaces

    Makerspaces are physical locations with equipment that students can use to undertake do-it-yourself (DIY) projects. Arguably, they have been around for decades; we just haven’t used the name makerspace. At my institution, the University of Massachusetts, Amherst, we’ve had a student-run DIY craft shop on our campus for more than 20 years.

    The difference between older forms of makerspaces like that craft shop and emerging ones is that the latter focus more heavily on digital making, such as 3-D design and printing, digital fabrication (sometimes called “FabLabs”), or the programming of open-source electronic hardware like the Arduino microcontroller. What is also new are the maker practices or principles of: 1) licensing digital designs and how-to instructions under a Creative Commons or similar copyright license and 2) openly sharing those designs through internet-enabled, cloud-based maker websites. Licenses chosen usually permit the sharing of the work with author attribution and, in some cases, permit new users to adapt and remix the work for other purposes. For example, at Thingiverse.com, 3-D modelers openly share their digital designs in this manner.

Here’s what we heard back.

  • Open-source RNA Analysis Tool Takes Root in Plant Biology

    An open-source RNA analysis platform has been successfully used on plant cells for the first time - a breakthrough that could herald a new era of fundamental research and bolster efforts to engineer more efficient food and biofuel crop plants.

    The technology, called Drop-seq, is a method for measuring the RNA present in individual cells, allowing scientists to see what genes are being expressed and how this relates to the specific functions of different cell types. Developed at Harvard Medical School in 2015, the freely shared protocol had previously only been used in animal cells.

    "This is really important in understanding plant biology," said lead researcher Diane Dickel, a scientist at the Department of Energy's Lawrence Berkeley National Lab (Berkeley Lab). "Like humans and mice, plants have multiple cell and tissue types within them. But learning about plants on a cellular level is a little bit harder because, unlike animals, plants have cell walls, which make it hard to open the cells up for genetic study."

    For many of the genes in plants, we have little to no understanding of what they actually do, Dickel explained. "But by knowing exactly what cell type or developmental stage a specific gene is expressed in, we can start getting a toehold into its function. In our study, we showed that Drop-seq can help us do this."

  • OpenStack Keeps One Eye on the Prize, One Over Its Shoulder

    The OpenStack Foundation (OSF) used its recent Open Infrastructure Show (OIS) to remind the open source community of its importance, maturity, and flexibility. But the event also showed that the group understands that the virtualized infrastructure environment is evolving rapidly.

    I must admit that heading into the OIS event I was not expecting much. Conversations I have had over the past year continued to show a strong core of OpenStack supporters, but it seemed that the platform’s innovative spirit was diminishing. And in such a rapidly evolving technology segment, any sort of diminishing momentum is the equivalent of going backwards.

    It is an open-source, accelerated-math library designed to help developers build and train machine-learning models using a wide range of hardware — CPUs, GPUs, and even specialized chips such as TPUs (Tensor Processing Units).

    While TensorFlow was originally designed for use with more powerful machines, it has evolved to be able to create models to run in all sorts of unlikely places, from browsers to low-power IoT devices. Today, TensorFlow can be used with a wide range of programming languages, including Python, Go, C++, Java, Swift, R, Julia, C#, Haskell, Rust, and JavaScript.

  • Google extends lowRISC FOSSi partnership

    Unlike proprietary processors, the design and instruction set architecture (ISA) for which are kept behind a typically expensive licence wall, free and open source silicon (FOSSi) does what it says on the tin: Projects like RISC-V provide both the ISA and key implementations under permissive licences, allowing anyone to use, modify, distribute, and commercialise the technology without a single license or royalty payment - including, in many cases, the ability to create a proprietary implementation, should they so choose.

    Following on from the news that it was a founding member of the Linux Foundation's CHIPS Alliance, an industry group set up to 'host and curate high-quality open source code relevant to the design of silicon devices', Google has now announced that it is extending its existing partnership with the lowRISC project to include additional funding, support, and the appointment of two Google staffers as board members on the project.

  • To Create Prosperity, Free Market Competition Isn’t Enough—You Need Collaboration Too

    What’s ironic is that all of this communal activity isn’t driven by beret-wearing revolutionaries plotting in coffee houses, but by many of today’s most powerful and profit-driven corporations, who act not out of altruism, but self-interest. The fact is that technology firms today who do not actively participate in open source communities are at a significant competitive disadvantage.

    For example, Chris DiBona, Director of Open Source at Google, once told me, “We released Android as an open source product because we knew that was the fastest way to grow adoption, which enabled us to preserve the relationships with customers for businesses like search, maps and Gmail.” That is the reality of today’s marketplace. You collaborate in order to compete effectively. Businesses that don’t accept that simple fact will find it difficult to survive.

    Science’s commitment to communal effort is not at all new, but is a thread running deep in America’s long history of technological dominance. And it’s not all about private companies competing with each other, either: it’s about how the market can benefit from public investment. When Vannevar Bush submitted his famous report, “Science, The Endless Frontier,” to President Truman at the end of World War II, he argued that scientific discovery should be considered a public good crucial to the competitiveness of the nation. The crux of his argument is that such efforts build capacity through creating what he called “scientific capital” and pointed out that “New products and new processes do not appear full-grown. They are founded on new principles and new conceptions, which in turn are painstakingly developed by research in the purest realms of science.”

  • The benefits of open source networking for enterprise IT

    Open source software has proved its benefits for various aspects of the IT community in terms of costs, agility and flexibility. Open source networking software is in its early stages of deployment among enterprises. Meantime, hyperscale cloud providers and the largest service providers have made effective use of open source networking.

    It is standard in large IT organizations to consider open source software alongside packaged software and SaaS as part of their IT architecture. Enterprise IT shops frequently deploy open source software in test environments and when designing new applications, like in DevOps.

    IT organizations report a range of benefits from open source software, including innovative design, time to market and agility. While open source software helps reduce some costs, deployment in production environments is generally accompanied by a vendor-supplied support contract.

  • How “Lab as a Service” supports OPNFV and ONAP development

    The Interoperability Lab at the University of New Hampshire (UNH-IOL) is a community resource that allows developers and open source users to have access to resources that they might not have themselves. The “Lab as a Service” provides the necessary shared compute and networking resources for developers working on projects such as OPNFV. Access is remote via a VPN connection, so it acts like a remote server. Those new to OPNFV can create a virtual deployment on a single node and run small VNFs on top. It gives developers access to a bare metal system for low level checking and installs. The next step is to add better support for multi-node usage, integrating the CI work that's being done in the OPNFV project and making the system more compatible with ONAP development.

  • Exclusive: Google suspends some business with Huawei after Trump blacklist
  • 5G and #Huawei – Trade wars can be prevented by using Open Source

    Consumer Choice Center Managing Director Fred Roeder stressed that more openness and transparency of telephone and radio networks could lead to more trust in the soft- and hardware of infrastructure providers: “Outright bans by country of origin should only be the last resort for policy makers. Bans risk getting the global economy deeper into costly trade wars. Consumers benefit from competition and the fast rollout of new technologies such as 5G networks. At the same time, we are worried about vulnerabilities and potential backdoors in equipment and software. Closed systems have a much higher likelihood of hiding vulnerabilities. Hence more open systems and open source approaches can really help consumers, and governments, trust the security promises of 5G providers,” said Roeder.

    “Private efforts such as the Open Radio Access Network Alliance show that open source systems are an option for telecommunication infrastructure. It would be a win-win situation for consumers and industry if more companies would embrace open standards. An open source approach in telecommunications could revolutionize market access and rollout pace of new standards in the era of 5G, in the same way as blockchain does in the financial services and payment industry. Manufacturers that commit to open source systems show that they don’t have any vulnerabilities to hide, and at the same time have a compelling case not to be excluded on the basis of their country of origin,” he added.

  • Why 5G is a huge future threat to privacy

    The next-generation of mobile communications, 5G, is currently a hot topic in two very different domains: technology – and politics. The latter is because of President Trump’s attempts to shut the Chinese telecoms giant Huawei out of Western procurement projects. That might work in the US, but the move is meeting a lot of resistance in Europe.

    There seem to be two primary concerns about allowing Chinese companies to build the new 5G infrastructure. One is a fear that it will help China consolidate its position as the leading nation in 5G technologies, and that it could come to be the dominant supplier of 5G hardware and software around the world. The other is more directly relevant to this blog: a worry that if Chinese companies install key elements of 5G systems, they will be able to spy on all the traffic passing through them. As the South China Morning Post reports, in an attempt to soothe those fears, Huawei has even promised to sign “no-spy agreements with governments“. That’s a rather ridiculous suggestion – as if signing an agreement would prevent Chinese intelligence agencies from using Huawei equipment for surveillance if they could.

  • Why the future of the cloud is in Linux

    Organisations today are investing in new technologies and practices to transform the way they deliver value to customers. This has become a critical investment area as we move into an era of disruption.

    Cloud computing plays a vital role in supporting both the technologies and processes driving the digital transformation imperative. Offering greater speed, cloud-based strategies leave more time for companies to focus on building and delivering innovation, value, and differentiation while creating financial efficiency.

    While moving to a single public cloud has many benefits, the reality is that for some workloads the public cloud simply doesn't make sense, or meet requirements for things like control, security or regulatory compliance. As a result, a majority of today's IT environments are inherently hybrid, comprising of applications deployed on-premises, and in both private and public clouds.

    The Cloud Native Computing Foundation (CNCF) Technical Oversight Committee (TOC) voted to accept CRI-O as an incubation-level hosted project on April 8th. CRI-O, created by Red Hat, is an Open Container Initiative (OCI) container runtime for Kubernetes that provides an alternative to Docker, rkt, or Moby.

    CRI-O is designed to work specifically with Kubernetes by delivering a minimal runtime that implements the standard components of the Kubernetes Container Runtime Interface (CRI). Early versions of Kubernetes only supported containers with the Docker runtime. As the Kubernetes team began to add support for new runtimes, such as rkt, they decided to develop and release CRI in order to decouple Kubernetes from specific container runtimes.

  • An Open Source ESC For Brushless Motors

    For something basic like a brushed DC motor, speed control can be quite simple, and powering up the motor is a simple matter of just applying voltage. Brushless motors are much more demanding in their requirements however, and won’t spin unless driven just right. [Electronoobs] has been exploring the design of a brushless speed controller, and just released version 1.0 of his open-source ESC design.

    The basic design is compact, and very similar to many off-the-shelf brushless ESCs in the low power range. There’s a small PCB packing a bank of MOSFETs to handle switching power to the coils of the motor, and a big capacitor to help deal with current spikes. The hacker staple ATMEGA328 is the microcontroller running the show. It’s a sensorless design, which measures the back EMF of the motor in order to determine when to fire the MOSFETs. This keeps things simple for low-torque, low-power applications.

  • A Customizable Open Source Mechanical Numpad

    Mechanical keyboards with reduced key counts are all the rage these days, but while those streamlined input devices might look cool on your desk, there are times when the traditional number pad or navigation keys are quite handy. Rather than just going without, [Mattia Dal Ben] decided to put together his own mechanical auxiliary input device for when the main board just isn’t cutting it.

  • Little Printer returns as an open-source messaging device

    Berg’s Little Printer, an adorable internet-connected box that printed out tiny snippets of news, Instagram photos, and to-do lists, stopped working when the studio and its servers shut down in 2014. Now, design consultancy firm Nord Projects has brought it back to life with a brand-new app, and it added the ability to send messages between devices, as reported by Core77.

  • Perfecting the Open Source RC Controller

    For this entry into the 2019 Hackaday Prize, [Vitor de Miranda Henrique] is working on his own version of the ultimate open source remote control. His design follows some of the trends we’ve already seen in terms of outward design and hardware expandability, but also branches off into some new territory with features such as dual integrated displays.

  • OpenGL 4.6 / SPIR-V Support Might Be Inching Closer For Mesa Drivers
    We're quickly approaching the two year anniversary of the OpenGL 4.6 release and it's looking like the Intel/RadeonSI drivers might be inching towards the finish line for that latest major revision of the graphics API.  As we've covered many times, the Mesa drivers have been held up on OpenGL 4.6 support due to their SPIR-V ingestion support mandated by this July 2017 version of the OpenGL specification. While there are the Intel and Radeon RADV Vulkan drivers already with the SPIR-V support that is central to Vulkan, it's taken a long time re-fitting the OpenGL drivers for the likes of ARB_gl_spriv. Then again, there aren't many (actually, any?) major OpenGL games requiring version 4.6 of the specification even with its interoperability benefits thanks to SPIR-V.

Software: Left, Samba, LaTeX, PyRadio and More

  • Left Is A Minimalist, Distraction-Free Text Editor For Writers
    Left is a free and open source distraction-free text editor for Linux, Windows and Mac. The main goal of Left is to get you to focus on writing. It comes with writing essentials like autocomplete, synonym suggestions and writing statistics, but it doesn't support text formatting, and doesn't have all the bells and whistles found in applications like LibreOffice Writer or Microsoft Office Word. This minimalist text editor may not be particularly exciting, and it's not for everyone, but if you're working on a long writing project, a clean interface that allows you to focus exclusively on your work may be for you.

  • 8 Best latex editors for Linux, Windows or MacOS
    LaTeX project is a programming language with which scientific and mathematical texts can be created. The full form of LaTeX here is Lamport TeX. In simple words, it is a document preparation system for high-quality typesetting but for special purposes where you need scientific and mathematical texts like scientific formulas for some academic books or PDF… Using packages or libraries, you can extend the scope of functions to create graphics and formulas. Now, what exactly is the LaTex editor? In simple words, the editor that supports LaTeX programming to create documents is called LaTeX editors. Thus, it is not like our normal word editor where we get formatted text in WYSIWYG (“what you see is what you get”) such as OpenOffice, LibreOffice or Microsoft Office. LaTeX is totally opposite uses a command line interface to format text for books or documents need an extensive text system that is intended for books, scientific papers and articles. Particularly in the mathematical-technical area, the system offers itself because of the formulas contained. You can simply install LaTeX on your system and then text can be entered in a simple editor and saved in a source text file, similar to a script. This text is supplemented by LaTeX commands, which, for example, identify chapters, sections, headings, and quotes. In addition, a LaTeX document can be spread over several files, so that each chapter is a separate file. However, there are a good number of best LaTeX backed editors are available for online to download with both open sources as well as a free license for Windows, Linux and MacOS. Thus, here we are with some best open source or free LaTeX editors but before installing them remember they are not simple text editors and to operate them, first, you must get familiar with the LaTeX commands…
  • PyRadio – curses based internet radio player
    On my roadmap is to review all actively maintained internet radio players. To date, I’ve covered odio, Shortwave, and Radiotray-NG. While there’s lots to admire in these projects, I feel that an internet radio player meeting all my requirements is still out there waiting to be discovered. For this review, I’ll run through PyRadio. Unlike the other radio players I’ve covered, PyRadio is curses based software.

This is yet another big deal contribution by Canonical's Daniel van Vugt as part of their GNOME desktop enhancements.
  • Firefox brings you smooth video playback with the world’s fastest AV1 decoder
    Tuesday’s release of Firefox 67 brought a number of performance enhancing features that make this our fastest browser ever. Among these is the high performance, royalty free AV1 video decoder dav1d, now enabled by default on all desktop platforms (Windows, OSX and Linux) for both 32-bit and 64-bit systems. With files more than 30% smaller than today’s most popular web codec VP9 [1], and nearly 50% smaller than its widely deployed predecessor H.264 [2], AV1 allows high-quality video experiences with a lot less network usage, and has the potential to transform how and where we watch video on the Internet. However, because AV1 is brand new and more sophisticated, some experts had predicted that market adoption would wait until 2020 when high-performance hardware decoders are expected. Dav1d in the browser upends these predictions.
  • GNU Binutils Begins Landing eBPF Support
    The GNU Binutils is finally getting wired up around the Extended BPF (eBPF) as the modern, in-kernel virtual machine that stretches the Berkeley Packet Filter beyond the networking subsystem.  Compiling for eBPF has most commonly been done by the LLVM eBPF back-end to allow compiling C into the eBPF bytecode but it looks like the GNU toolchain developers are looking to increase their support around the increasingly common eBPF use-cases for this in-kernel VM.

  • Archiving 26 500 community Q&As from Ask Fedora
    Ask Fedora is the Fedora Linux community’s questions-and-answers portal, and it recently transitioned from a forum software called Askbot to Discourse. Changing the underlying forum software doesn’t have to be destructive but Ask Fedora decided to go with a nuke-and-pave migration strategy: They decided to start from scratch instead of copying user accounts and the user-contributed content to the new software. The first time I learned of the migration was a few days after it had happen. I’d run into an issue with my Fedora installation and went online looking for solutions. Every useful search result was from the old Ask Fedora site and every link returned an HTTP 404 Not Found error message as those answers hadn’t been migrated to the new Ask Fedora website.
  • Attention epel6 and epel7 ppc64 users
    If you are a epel6 or epel7 user on the ppc64 platform, I have some sad news for you. If you aren’t feel free to read on for a tale of eol architectures. ppc64 (the big endian version of power) was shipped with RHEL6 and RHEL7 and Fedora until Fedora 28. It’s been replaced by the ppc64le (little endian) version in Fedora and RHEL8.
  • Optional dependencies don’t work
    In the i3 projects, we have always tried hard to avoid optional dependencies. There are a number of reasons behind it, and as I have recently encountered some of the downsides of optional dependencies firsthand, I summarized my thoughts in this article. [...] Software is usually not built by end users, but by packagers, at least when we are talking about Open Source. Hence, end users don’t see the knob for the optional dependency, they are just presented with the fait accompli: their version of the software behaves differently than other versions of the same software. Depending on the kind of software, this situation can be made obvious to the user: for example, if the optional dependency is needed to print documents, the program can produce an appropriate error message when the user tries to print a document. Sometimes, this isn’t possible: when i3 introduced an optional dependency on cairo and pangocairo, the behavior itself (rendering window titles) worked in all configurations, but non-ASCII characters might break depending on whether i3 was compiled with cairo. For users, it is frustrating to only discover in conversation that a program has a feature that the user is interested in, but it’s not available on their computer. For support, this situation can be hard to detect, and even harder to resolve to the user’s satisfaction.

Servers: Kubernetes, Microservices, Containers and SUSE's Enterprise Storage 6

  • Is bare Kubernetes still too messy for enterprises?
    Kubernetes is touted as a computing cure-all, fixing up multicloud networking to data mobility. The open-source platform for orchestrating containers (a virtualized method for running distributed applications) may or may not be the panacea it’s hyped up to be. What is certain is that user-ready Kubernetes isn’t as easy as it sounds, so customers should shop carefully for a provider. Enterprise users of Kubernetes and containers may not guess just how many moving parts are under the covers. There are a ton of tiny pieces that have to line up just so in order for them to work, according to Mark Shuttleworth (pictured), founder and chief executive officer of Canonical Ltd. He likens these technologies to carefully constructed “fictions.”
  • Data as a microservice: Distributed data-focused integration
    Microservices is the architecture design favored in new software projects; however, getting the most from this type of approach requires overcoming several previous requirements. As the evolution from a monolithic to a distributed system takes place not only in the application space but also at the data store, managing your data becomes one of the hardest challenges. This article examines some of the considerations for implementing data as a service.
  • Container Adoption Shoots Up Among Enterprises In 2019: Survey
    Majority of IT professionals now run container technologies, with 90 percent of those running in production and 7 in 10 running at least 40 percent of their application portfolio in containers — an impressive increase from two years ago, when just 67 percent of teams were running container technologies in production. According to the joint 2019 Annual Container Adoption Survey released by Portworx and Aqua Security, enterprises have started making bigger investments in containers. In 2019, nearly one in five organizations is found to be spending over $1 million annually on containers (17%) as compared to just four percent in 2016.
  • SUSE Rolls Out Enterprise Storage 6
    SUSE has announced the latest version of its software-defined storage solution powered by Ceph technology. With SUSE Enterprise Storage 6, IT organizations can adapt to changing business demands. They may also reduce IT operational expense with new features focused on containerized and cloud workload support, improved integration with public cloud, and enhanced data protection capabilities, SUSE said.
