    It’s Season 12 Episode 07 of the Ubuntu Podcast! Alan Pope, Mark Johnson and Martin Wimpress are connected and speaking to your brain.

  • 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.

  • 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.

    The Samba Team announced the availability of Samba 4.10.4.

    This is the latest stable release of the Samba 4.10 release series.

    Also, they released a patch against Samba 4.10.3.

    This release comes with close to 40 bug fixes.

  • 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.

    In addition to GNOME's Mutter compositor / window manager seeing an important fix recently lowering the output lag under X11 so it matches GNOME's Wayland performance, another important Mutter fix also landed.

    The Mutter/Clutter change to avoid skipping over the next frame to render has landed. 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.

  • 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 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.

  • Red Hat completes open sourcing of 3scale code

    At Red Hat we have always been proud of our open source heritage and commitment. We are delighted that more of the industry now shares our viewpoint, and more companies are looking to promote their open source bona fides of late.

    Open source software energizes developers and teams of committed developers working in parallel can outproduce the large development hierarchies of the last generation. We believe working upstream with open source communities is an important innovation strategy.

    Occasionally, however, innovation does originate in traditional commercial organizations under a proprietary development model. Three years ago, Red Hat discovered just such a company that was doing exciting things in the API economy.

In 2020, The Document Foundation will be on stage at many FOSS events around the world, and the LibreOffice Conference will be the most important of the year. Organizing this conference is a unique opportunity for FOSS communities, because the event will make the history of free open source software.

  • DataStax and the Modern Commercial Open Source Business

    One month ago, Google announced a set of partnerships with seven commercial open source providers. Among those announced was DataStax, which held its annual conference this year and, for the first time, an analyst day. While DataStax and the open source project it is based on, Cassandra, are differentiated on a technical basis, the company also represents an interesting contrast with its peers directionally both among the newly minted Google partners and more broadly.

    Of the seven commercial open source partners Google announced, for example, DataStax is one of two along with InfluxData that has not introduced a non-open source, hybrid license as a means of protecting itself from competition from the cloud providers. This is not, notably, because the company doesn’t seem them as a threat; asked about who the competition was in the analyst sessions, the CEO of DataStax candidly acknowledged that the company’s primary competitive focus was not on premise competition such as Oracle, but cloud-based managed services offerings.

Linux Mint Turns Cinnamon Experience Bittersweet

Filed under
Reviews

Linux Mint no longer may be an ideal choice for above-par performance out of the box, but it still can serve diehard users well with the right amount of post-installation tinkering.

The Linux Mint distro clearly is the gold standard for measuring Cinnamon desktop integration. Linux Mint's developers turned the GNOME desktop alternative into one of the best Linux desktop choices. Linux Mint Cinnamon, however, may have lost some of its fresh minty flavor.

The gold standard for version 19.1 Tessa seems to be a bit tarnished when compared to some other distros offering a Cinnamon environment. Given that the current Linux Mint version was released at the end of last December, it may be a bit odd for me to focus on a review some five months later.

Linux Mint is my primary driver, though, so at long last I am getting around to sharing my lukewarm experiences. I have run Linux Mint Cinnamon on three primary work and testing computers since parting company with Ubuntu Linux Unity and several other Ubuntu flavors many years ago. I have recommended Linux Mint enthusiastically to associates and readers in my personal and professional roles.

  • Cardlings looks to be an interesting turn-based strategy with an usual gameplay style

    Cardlings caught my attention recently, a unique turn-based strategy game from Clockwork Chilli that's confirmed to be releasing for Linux on June 5th.

    What's interesting about it, is the way the turns work. While one player is doing combat and movement, the other player has the chance to get building and gathering resources. To make it even more unique, only the player doing movement and combat can end the turn and then it's reversed. So this means the player doing the moment, will want to end the turn quickly so the other player doesn't get tons of resources and buildings set up. The developer said this "results in very intense, fast-paced games that still preserve all the depth of more traditional turn-based strategy titles".

  • Incredibly weird comedy point and click adventure 'Clam Man' is out

    Clam Man from Team Clam is a new comedy adventure game, it just recently released with Linux support. It's a point and click adventure, although it has a focus on the story rather than pushing you through puzzles.

  • Comedy adventure Nelly Cootalot: Spoonbeaks Ahoy! HD is now out with Linux support

    Originally released in 2007, Nelly Cootalot: Spoonbeaks Ahoy! HD revamps the experience to make it less painful to play on modern systems with full Linux support.

  • Unique gravity-defying metroidvania 'Dandara' finally sees an update to the Linux version

    Dandara, a very unique take on the action metroidvania genre took me by surprise with the fun gameplay last month and now the Linux version is actually up to date.

    The main problem, as noted in the previous article, was that the Linux version of Dandara hadn't seen any updates since release. The developer, Long Hat House, actually emailed in last night to note that the whole game has been updated and they've managed to now get the Linux version on equal footing too.

  • Steam Play updated again to 4.2-5 to include newer DXVK, networking and controller fixes

    Valve have pushed out the latest smaller update to Steam Play, this time including an updated DXVK and a bunch of fixes for various games.

    Ever since I first heard of Eagle Island I was basically in love, with super slick pixel-art and an owl you throw as your weapon? Sign me up.

    The demo just recently went live on Steam, including for Linux and after giving it a go I've come away from it extremely impressed. It works beautifully and it looks gorgeous, probably one of the best demos I've played for some time. I even joked about the demo splash-screen missing a Linux icon with the developer on Twitter, which they took it rather well as they just haven't yet found a good one to use.

  • Why a Windows flaw patched nine days ago is still spooking the Internet

    The vulnerability resides in Microsoft’s proprietary Remote Desktop Protocol, which provides a graphical interface for connecting to another computer over the Internet. Exploiting the vulnerability—which is present in older versions of Windows but not the much better secured Windows 8 and 10—requires only that an attacker send specific packets to a vulnerable RDP-enabled computer. In a testament to the severity, Microsoft took the highly unusual step of issuing patches for Windows 2003, XP, and Vista, which haven’t been supported in four, five, and seven years, respectively.

Choosing the right model for maintaining and enhancing your IoT project

Filed under
Linux

In today's connected embedded device market, driven by the Internet of things (IoT), a large share of devices in development are based on Linux of one form or another. The prevalence of low-cost boards with ready-made Linux distributions is a key driver in this. Acquiring hardware, building your custom code, connecting the devices to other hardware peripherals and the internet as well as device management using commercial cloud providers has never been easier. A developer or development team can quickly prototype a new application and get the devices in the hands of potential users. This is a good thing and results in many interesting new applications, as well as many questionable ones.

When planning a system design for beyond the prototyping phase, things get a little more complex. In this post, we want to consider mechanisms for developing and maintaining your base operating system (OS) image. There are many tools to help with this but we won't be discussing individual tools; of interest here is the underlying model for maintaining and enhancing this image and how it will make your life better or worse.

  • AMD GCN GPU Target Continuing To Improve For The GCC 10 Compiler

    With the recent release of the GCC 9 stable compiler there is the initial "AMD GCN" GPU target/back-end merged. However, for this GNU Compiler Collection release the AMD GCN target isn't all that useful but continued work on it gives us hope of seeing it in good shape for next year's GCC 10 release.

    With the GCC 9.1 release, the AMD GCN back-end can only handle running basic single-threaded programs... Not exactly useful for graphics cards. The GCC 9 code supports targeting the Fiji and Vega 10 GCN instruction set architecture.

  • Little Trouble in Big Data – Part 1

    A few months ago, we received a phone call from a bioinformatics group at a European university. The problem they were having appeared very simple. They wanted to know how to usemmap() to be able to load a large data set into RAM at once. OK I thought, no problem, I can handle that one. Turns out this has grown into a complex and interesting exercise in profiling and threading.

    The background is that they are performing Markov-Chain Monte Carlo simulations by sampling at random from data sets containing SNP (pronounced “snips”) genetic markers for a selection of people. It boils down to a large 2D matrix of floats where each column corresponds to an SNP and each row to a person. They provided some small and medium sized data sets for me to test with, but their full data set consists of 500,000 people with 38 million SNP genetic markers!

  • Why precompiled headers do (not) improve C++ compile times

    Would you like your C++ code to compile twice as fast (or more)?

    Yeah, so would I. Who wouldn't. C++ is notorious for taking its sweet time to get compiled. I never really cared about PCHs when I worked on KDE, I think I might have tried them once for something and it didn't seem to do a thing. In 2012, while working on LibreOffice, I noticed its build system used to have PCH support, but it had been nuked, with the usual poor OOo/LO style of a commit message stating the obvious (what) without bothering to state the useful (why). For whatever reason, that caught my attention, reportedly PCHs saved a lot of build time with MSVC, so I tried it and it did. And me having brought the PCH support back from the graveyard means that e.g. the Calc module does not take 5:30m to build on a (very) powerful machine, but only 1:45m. That's only one third of the time.

    In line with my previous experience, on Linux that did nothing. I made the build system support also PCH with GCC and Clang, because it was there and it was simple to support it too, but there was no point. I don't think anybody has ever used that for real.

    Then, about a year ago, I happened to be working on a relatively small C++ project that used some kind of an obscure build system called Premake I had never heard of before. While fixing something in it I noticed it also had PCH support, so guess what, I of course enabled it for the project. It again made the project build faster on Windows. And, on Linux, it did too. Color me surprised.

  • Ubuntu 19.10 To Bundle NVIDIA's Proprietary Driver Packages As Part Of Its ISO

    For Ubuntu 19.10 the developers are adding the NVIDIA driver packages onto the ISO. The NVIDIA binary drivers won't be activated by default, but will be present on the install media to make it easier to enable post-install.

    The open-source NVIDIA "Nouveau" drivers will remain the default for NVIDIA graphics on new Ubuntu installations, but this change is positioning the mainline and legacy NVIDIA proprietary drivers onto the Ubuntu ISO so that they can be easily obtained locally post-install. The main driver here is allowing users to enable the NVIDIA proprietary graphics on Ubuntu even if you don't have an Internet connection. NVIDIA has already okay'ed the distribution of their driver packages with the Ubuntu ISO.

  • Snapcraft parts & plugins

    Last week, we published Introduction to snapcraft, a tutorial that provided a detailed overview of the snap build process. We touched on the concepts like snap ecosystem components, snapcraft command line, snapcraft.yaml syntax, and more. We’d like to expand on the first lesson, and today, we are going to talk about parts and plugins, used in the build process of snaps.

  • Arronax – Graphical Tool to Create Desktop Launcher in Ubuntu

    For those who want to manually create desktop shortcut launcher in Ubuntu 16.04, Ubuntu 18.04, Ubuntu 19.04, Arronax is a good choice with graphical user interface.

    Other than creating .desktop file via Linux command, Arronax offers a graphical interface to create (and also edit) desktop shortcut for application, executable file, or URL.

  • Valve's Proton Pulls In Latest DXVK, Steam Networking Updates, Controller Layout Fixes

    The Valve developers maintaining their Proton fork of Wine for use by Steam Play have outed a new update, version 4.2-5.

  • Wine & Mingw-w64 Might Tighten Up Their Relationship - Possible "WineSDK"

    Developers between the Wine and Mingw-w64 projects are discussing the potential for further embracing their relationship given the overlap in trajectory and both benefiting from close collaboration. This extended relationship could also involve Mingw-w64 potentially adopting Wine's branding.

    While all Phoronix readers should be aware of Wine, for those not familiar with Mingw-w64 it's the off-shoot of MinGW focused on 64-bit support and other features over the original MinGW for providing an open-source development toolchain for Microsoft Windows. Mingw-w64 remains quite active in working on its GCC-based compiler toolchain support for Windows.

  • Wine and mingw-w64 cooperation
  • IRKALLA, an incredibly stylish looking pixel-art tactical-action platformer is coming to Linux

    The developers behind IRKALLA emailed in today and it grabbed my interest right away with the supremely stylish art behind it. The odd setting has my curiosity too, with mechs versus demons!

    According to the developer, it's a "platform-tactic game" so it has elements of an action platformer with character progression and some form of base defence building. IRKALLA has been in development for quite a few years now with their TIGForum post dating all the way back to 2013. We've been emailed today, as it seems development on it has been picked back up as they told me it's "finally coming together" and a Linux release is also confirmed of course.

  • Roguelike fantasy adventure 'Vambrace: Cold Soul' has a new feature trailer ahead of release next week

    The release of Vambrace: Cold Soul on May 28th is getting close now, it's quite an impressive looking game that I've been playing and they have a new feature trailer. I won't say too much on it myself before release but since I've had access for a while, I can say it works great on Linux.

  • Surreal adventure game 'ZED' about an artist suffering from dementia is releasing in June

    ZED, a game that will tell the story of an artist suffering from dementia from Eagre Games and Cyan Ventures now has a release date and it's quite soon.

    The Windows version is now scheduled in for June 4th, with the Linux (and Mac) version to be "later in June". Great to see it continue to be confirmed and although there is a delay, it's not going to be long it seems. Good thing too, as I'm damn excited for this one.

  • art of rally is bringing a stylized racing experience to Linux later this year

    Funselektor Labs, the developer of Absolute Drift has announced their latest game, art of rally. It might look stylish but it's not just a pretty face, as the developer is also focused on how the cars handle too.

    While we have a few racing games now like Grid Autosport, DiRT Rally/4 and some F1 games (plus a few that work with Steam Play), they're all quite serious business. art of rally looks to be taking a slightly less realistic focus while still providing a challenge, especially with the top-down view you get a better picture of what's up ahead.

Distros: Draco in Sparky, Fedora Issues and Optional Dependencies in Debian

  • Draco Desktop
    There is a new desktop available for Sparkers: Draco
  • 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.

OSS: 3scale, Wikipedia Edit-a-thon, LibreOffice Conference 2020, DataStax Openwashing and IGEL

  • Red Hat completes open sourcing of 3scale code
    At Red Hat we have always been proud of our open source heritage and commitment. We are delighted that more of the industry now shares our viewpoint, and more companies are looking to promote their open source bona fides of late. Open source software energizes developers and teams of committed developers working in parallel can outproduce the large development hierarchies of the last generation. We believe working upstream with open source communities is an important innovation strategy. Occasionally, however, innovation does originate in traditional commercial organizations under a proprietary development model. Three years ago, Red Hat discovered just such a company that was doing exciting things in the API economy.
  • Enbies and women in FOSS Wikipedia edit-a-thon
    To be brief, I’ll be hosting a Wikipedia edit-a-thon on enbies and women in free and open source software, on June 2nd, from 16:00 – 19:00 EDT. I’d love remote participants, but if you’re in the Boston area you are more than welcome over to my place for pancakes and collaboration times.
  • LibreOffice Conference 2020, it could be in your city
    LibreOffice Conference 2020 will be an event to remember, for a couple of reasons: it will be the 10th of a series of successful conferences, and it will celebrate the 10th anniversary of the LibreOffice project and the 20th of the FOSS office suite. In 2020, The Document Foundation will be on stage at many FOSS events around the world, and the LibreOffice Conference will be the most important of the year. Organizing this conference is a unique opportunity for FOSS communities, because the event will make the history of free open source software.
  • DataStax and the Modern Commercial Open Source Business
    One month ago, Google announced a set of partnerships with seven commercial open source providers. Among those announced was DataStax, which held its annual conference this year and, for the first time, an analyst day. While DataStax and the open source project it is based on, Cassandra, are differentiated on a technical basis, the company also represents an interesting contrast with its peers directionally both among the newly minted Google partners and more broadly. Of the seven commercial open source partners Google announced, for example, DataStax is one of two along with InfluxData that has not introduced a non-open source, hybrid license as a means of protecting itself from competition from the cloud providers. This is not, notably, because the company doesn’t seem them as a threat; asked about who the competition was in the analyst sessions, the CEO of DataStax candidly acknowledged that the company’s primary competitive focus was not on premise competition such as Oracle, but cloud-based managed services offerings.

Linux Mint Turns Cinnamon Experience Bittersweet

Linux Mint no longer may be an ideal choice for above-par performance out of the box, but it still can serve diehard users well with the right amount of post-installation tinkering. The Linux Mint distro clearly is the gold standard for measuring Cinnamon desktop integration. Linux Mint's developers turned the GNOME desktop alternative into one of the best Linux desktop choices. Linux Mint Cinnamon, however, may have lost some of its fresh minty flavor. The gold standard for version 19.1 Tessa seems to be a bit tarnished when compared to some other distros offering a Cinnamon environment. Given that the current Linux Mint version was released at the end of last December, it may be a bit odd for me to focus on a review some five months later. Linux Mint is my primary driver, though, so at long last I am getting around to sharing my lukewarm experiences. I have run Linux Mint Cinnamon on three primary work and testing computers since parting company with Ubuntu Linux Unity and several other Ubuntu flavors many years ago. I have recommended Linux Mint enthusiastically to associates and readers in my personal and professional roles. Read more
