  • Docker at Four: The State of the Docker Ecosystem from 2013 to Today

    Docker containers turned four years old this month. If you were paying attention to Docker in its early days, you know that the Docker ecosystem today looks nothing like it did then. Here's how the Docker world has evolved since Docker's launch in 2013.

  • Kubernetes Federation in a Post-Configuration Management Universe

    When containerization was young, one of its early principles was the ideal of immutable infrastructure, the ability to build a support structure for a container that was flexible enough to meet the container’s needs during its lifespan, which may be short, but remained a fixed asset throughout that duration.

  • Cloud Native Computing Foundation Welcomes Containerd and Rkt as New Projects

    At the CloudNative/Kubecon EU event in Berlin on March 29, the big news was that Docker contributed its containerd runtime, while CoreOS contributed its rkt (pronounced rocket) runtime to the Cloud Native Computing Foundation (CNCF). The containerd and rkt projects are rival container runtimes that aim to implement specifications that are being formally defined by the Open Container Initiative (OCI) project.

  • Why Kubernetes Sucks and How to Fix It

    Joe Beda is in a better position than most to understand what's wrong with Kubernetes. Beda helped to start the Kubernetes project while he was at Google; he now runs a startup called Heptio that is aiming to help further enable Kubernetes.

    At the Kubecon / CloudNative EU conference in Berlin, Beda delivered a keynote address on what needs to change in Kubernetes to bring in more users.

  • Getting more out of Qt Quick with OpenVG

    In Qt 5.9 is now possible to render Qt Quick applications with OpenVG when using hardware that supports it. This is made possible by a new scene graph adaptation that uses EGL and OpenVG to render Qt Quick scenes. When using Qt for Device Creation, it means that it now be possible to run with graphics hardware acceleration on some devices where today only software rendering is available.

  • Qt 5.9's OpenVG Renderer For Hardware Lacking OpenGL

    One of the many new features for the upcoming Qt 5.9 is an OpenVG renderer for hardware acceleration on some embedded platforms that lack OpenGL capabilities.

    OpenVG for the uninitiated is a 2D vector graphics API backed by The Khronos Group. It hasn't been updated in almost one decade with OpenGL ES largely taking over on the mobile/embedded front, but there still is some embedded hardware out there with still having OpenVG v1.1 drivers. There used to be an OpenVG state tracker in Mesa's Gallium3D, but that's long been dead.

  • Kdenlive status update

    Ever since the port to QT5/KF5 in 2015, Kdenlive has seen an increasing momentum to developing its full potential in being a stable and reliable video editing tool which the FLOSS community can use to create content and democratize communication. In 2016 the project saw a redesign of its visual identity (logo, website), the reintroduction of some much requested tools like rotoscoping and a Windows port. During these couple of years we’ve seen a boom in the size of the community.

  • Kdenlive's Status Ahead Of 17.04

    The Kdenlive video editor project in the KDE camp has published a new status update concerning the health of the project.

    Kdenlive developers continue seeing momentum building around their video editor since reviving it with the transition to Qt5 and KDE Frameworks 5. Over the past year they have added many tools, a Windows port, and other efforts to make Kdenlive pro-capable.

  • Tearing with Nvidia Proprietary Drivers on Plasma? Try this.

    This is a neat little trick that’s been making the rounds, and after seeing success with several people on Reddit I thought it was worth posting somewhere more visible. This will look at removing screen tearing (often entirely) when using Nvidia Proprietary graphics on the Plasma Desktop.

    Before I started looking for a solution to my PDF question, I had never considered using open source solutions to customize Adobe InDesign. After this exploration, I have expanded my knowledge of open source capabilities and just how valuable and useful open source solutions are, even when working in conjunction with a closed source application.

  • Does Adobe Hate Linux?

    As the press prepares to cover the release of Ubuntu 17.04, it should be clear in the tech industry just how big of a player Ubuntu is to the ecosystem. While a good bit of reviews will focus on what’s new in the release and what’s headed down the pipeline, I’d like to comment on what’s still missing and better yet, what can be done about it.

    What’s missing is a graphics suite and there’s really no excuse for not having one. Yes, we have graphics applications, but there are advantages to having a suite, not just a one-off application that can do something in 12 steps when its competitor can do it in three. The industry leader in this market is Adobe, whose Creative Cloud suite is leaps and bounds away from its competitors in terms of market share.

This week in KDE: fixing up Plasma 5.20

Okular’s editable forms are no longer mis-rendered when inertially scrolling (Kezi Olio, Okular 1.11.2) When your scanner can almost but not quite fit a particular page size, Skanlite will now display the option to scan to that page size anyway (e.g. 215mm wide scan beds now give you the option to scan using the US Letter page size) (Kåre Särs, libksane 20.12) The text of Elisa’s keyboard shortcuts are now translated properly (Nikunj Goyal, Elisa 20.12) Clearing the clipboard history on Wayland no longer crashes Plasma (David Edmundson, Plasma 5.20) Improved the Plasma SVG cache heuristics such that various things which might sometimes be invisible after upgrading Plasma now show up like they’re supposed to (Arjen Hiemstra, Plasma 5.20) On Wayland, clicking on a Task Manager entry while that entry’s tooltip is visible no longer crashes Plasma (Vlad Zahorodnii, Plasma 5.20) On Wayland, clicking on a Task Manager thumbnail now activates that window, as you would expect (Marco Martin, Plasma 5.20) Read more Also: KDE Plasma 5.20 Should Be Crashing A Lot Less Under Wayland

Legacy: Dennis Ritchie's Lost Dissertation and FTP Fadeout

  • Discovering Computer Legend Dennis Ritchie's Lost Dissertation
  • FTP Fadeout

    Here’s a small piece of news you may have missed while you were trying to rebuild your entire life to fit inside your tiny apartment at the beginning of the COVID crisis: Because of the way that the virus shook up just about everything, Google skipped the release of Chrome version 82. Who cares, you think? Well, users of FTP, or the File Transfer Protocol. During the pandemic, Google delayed its plan to kill FTP, and now that things have settled to some degree, Google recently announced that it is going back for the kill with Chrome version 86, which deprecates the support once again, and will kill it for good in Chrome 88. (Mozilla announced similar plans for Firefox, citing security reasons and the age of the underlying code.) It is one of the oldest protocols the mainstream [Internet] supports—it turns 50 next year—but those mainstream applications are about to leave it behind. Today’s Tedium talks about history of FTP, the networking protocol that has held on longer than pretty much any other.

virt-manager 3.0.0 released!

Yesterday I released virt-manager 3.0.0. Despite the major version number bump, things shouldn't look too different from the previous release. For me the major version number bump reflects certain feature removals (like dropping virt-convert), and the large amount of internal code changes that were done, though there's a few long awaited features sprinkled in like virt-install --cloud-init support which I plan to write more about later.

  • 7 Alternatives to Google Earth

    Google Earth has received so much press coverage that many users will appreciate that it is one of the coolest applications to download. In brief, it is a feature-laden 3D virtual globe, map and geography browser which lets users zoom in on their world with fantastic detail. View satellite imagery, maps, terrain, 3D buildings and even explore galaxies in the sky. This application allows the exploration of rich geographical content, save toured places and share with others. The software maps the earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. Google Earth is undoubtedly a very impressive application, and it is extremely hard not to admire the wealth of features that it offers. Its satellite images are unrivaled, it provides useful and accurate statistical information, and the software has many practical benefits, such as helping to find locations and give driving directions. In terms of functionality, this application earns our highest praise. We use the software on a regular basis on both desktop and mobile devices (the latter under Android). However, while Google Earth is available to download without charge, Google do not release the software under an open source license. In the past there have been attempts to reverse engineer Google Earth and implement its features in an open and extensible way. However, these actions were understandably frowned upon by Google. Instead we prefer to see the development of open source virtual globe software which uses freely licensed or public domain data. While the development of open source virtual globe applications may not, in itself, encourage Google to release its application or data under a similar license, it does give users the option to be able to have the freedom to do what they want. This route also helps to foster greater user community support to drive development often in the form of add-ons and plug-ins. There are a number of applications which are credible open source alternatives to Google Earth. While none of the software applications featured in this article have all of the features offered by Google Earth (although some offer some different features), and they are not exactly comparable, they are all worthy of investigating.

  • Warzone 2100 Lands Vulkan Renderer, Adaptive V-Sync For 20+ Year Old Game

    Warzone 2100 as the real-time strategy/tactics game that first premiered in 1999 before becoming open-source in 2004 and then fully open-source with game data in 2008 is now evolving in 2020 with Vulkan graphics support. The open-source Warzone 2100 game not only has a Vulkan back-end that was merged today but also OpenGL ES 2.0/3.0 support for those wanting to relive this late 90's computer game on mobile/embedded devices having only GLES drivers.

  • [NetBSD] Curses Library Automated Testing

    My GSoC project under NetBSD involves the development of the test framework of curses. This is the final blog report in a series of blog reports; you can look at the first report and second report of the series. The first report gives a brief introduction of the project and some insights into the curses testframe through its architecture and language. To someone who wants to contribute to the test suite, this blog can act as the quick guide of how things work internally. Meanwhile, the second report discusses some of the concepts that were quite challenging for me to understand. I wanted to share them with those who may face such a challenge. Both of these reports also cover the progress made in various phases of the Summer of Code. This being the final report in the series, I would love to share my experience throughout the project. I would be sharing some of the learning as well as caveats that I faced in the project.

  • [NetBSD] RumpKernel Syscall Fuzzing

    The first and second coding period was entirely dedicated to fuzzing rumpkernel syscalls using hongfuzz. Initially a dumb fuzzer was developed to start fuzzing but it soon reached its limits. For the duration of second coding peroid we concentrated on crash reproduction and adding grammar to the fuzzer which yielded in better results as we tested on a bug in ioctl with grammar. Although this works for now crash reproduction needs to be improved to generate a working c reproducer. For the last coding period I have looked into the internals of syzkaller to understand how it pregenerates input and how it mutates data. I have continued to work on integrating buildrump.sh with build.sh. buildrump eases the task fo building the rumpkernel on any host for any target. buildrump.sh is like a wrapper around build.sh to build the tools and rumpkernel from the source relevant to rumpkernel. So I worked to get buildrump.sh working with netbsd-src. Building the toolchain was successfull from netbsd-src. So binaries like rumpmake work just fine to continue building the rumpkernel.

  • Bandwidth for Video Conferencing

    For the Linux Users of Victoria (LUV) I’ve run video conferences on Jitsi and BBB (see my previous post about BBB vs Jitsi [1]). One issue with video conferences is the bandwidth requirements. The place I’m hosting my video conference server has a NBN link with allegedly 40Mb/s transmission speed and 100Mb/s reception speed. My tests show that it can transmit at about 37Mb/s and receive at speeds significantly higher than that but also quite a bit lower than 100Mb/s (around 60 or 70Mb/s). For a video conference server you have a small number of sources of video and audio and a larger number of targets as usually most people will have their microphones muted and video cameras turned off. This means that the transmission speed is the bottleneck. In every test the reception speed was well below half the transmission speed, so the tests confirmed my expectation that transmission was the only bottleneck, but the reception speed was higher than I had expected. When we tested bandwidth use the maximum upload speed we saw was about 4MB/s (32Mb/s) with 8+ video cameras and maybe 20 people seeing some of the video (with a bit of lag). We used 3.5MB/s (28Mb/s) when we only had 6 cameras which seemed to be the maximum for good performance.

  • Lack of Qualified Linux Talent Impedes Enterprise Move to the Clouds

    The Linux Foundation has been working to address the shortage of Linux talent for many years with a combination of training and certification exams. Despite this, the breathtaking growth in Linux adoption, especially as the de facto OS of the cloud, means that there is still a shortage of qualified talent, according to Clyde Seepersad, senior vice president and general manager for training and certification at The Linux Foundation (LF). “We are always supportive of developments in the training ecosystem which help address this gap. In particular, we are finding that demand for our performance-based certification exams continues to be gated by individuals not feeling adequately prepared,” he told LinuxInsider. LF’s certification exams include Certified Kubernetes Administrator, Certified Kubernetes Application Developer, Linux Foundation Certified SysAdmin, and Linux Foundation Certified Engineer. “ACG and LA both have excellent reputations for the quality of their open-source training content so we are pleased to see them come together to better serve the talent development needs of the open-source software ecosystem,” he added.

  • Last phase of the desktop wars?

    Economic pressure will be on Microsoft to deprecate the emulation layer. Partly because it’s entirely a cost center. Partly because they want to reduce the complexity cost of running Azure. Every increment of Windows/Linux convergence helps with that – reduces administration and the expected volume of support traffic. Eventually, Microsoft announces upcoming end-of-life on the Windows emulation. The OS itself , and its userland tools, has for some time already been Linux underneath a carefully preserved old-Windows UI. Third-party software providers stop shipping Windows binaries in favor of ELF binaries with a pure Linux API… …and Linux finally wins the desktop wars, not by displacing Windows but by co-opting it. Perhaps this is always how it had to be.
