  • 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.

    For my job, I must use InDesign. For freelance work, I use InDesign, Scribus, GIMP, and Photoshop, depending on whether I am creating the artwork or starting with someone else's work.

    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.

Zapcc Liberated, HMM and GPL

  • Zapcc high-speed C++ compiler now open source
    Zapcc, a caching C++ compiler built for speed, has gone open source. Ceemple Software, Zapcc’s builder, claims the compiler offers dramatic improvements in both incremental and full builds compared to building with Clang 4.0 and Clang 5.0. Based on heavily modified code from the Clang compiler project, Zapcc uses an in-memory compilation cache in a client-server architecture. All compilation information is remembered between runs.
  • Heterogeneous memory management meets EXPORT_SYMBOL_GPL()
    One of the many longstanding — though unwritten — rules of kernel development is that infrastructure is not merged until at least one user for that infrastructure exists. That helps developers evaluate potential interfaces and be sure that the proposed addition is truly needed. A big exception to this rule was made when the heterogeneous memory management (HMM) code was merged, though. One of the reasons for the lack of users in this case turns out to be that many of the use cases are proprietary; that has led to some disagreements over the GPL-only status of an exported kernel symbol. The HMM subsystem exists to support peripherals that have direct access to system memory through their own memory-management units. It allows the ownership of ranges of memory to be passed back and forth and notifies peripherals of changes in memory mappings to keep everything working well together. HMM is not a small or simple subsystem, and bringing it into the kernel has forced a number of low-level memory-management changes. After a multi-year development process, the core HMM code was merged for the 4.14 kernel, despite the lack of any users.

Software: elementary OS Software, Unified Modeling Language (UML), PulseAudio 12.0 and Zstd

  • An Awesome List of Apps & Resources for elementary OS
    It is barely up to a day since I put up a positive review of elementary OS which is well deserved because it has come a long way from what it was 2 years ago when FossMint checked it out. The good news I’ve got for you today is that the developers have published a page on GitHub that contains “curated list of awesome applications, tools and shiny things for elementary OS”. They are grouped into categories for easy selection, are all open source, and clicking on the green tick icons will direct you to the app on elementary OS’s AppCenter.
  • Best Free Unified Modeling Language Tools
    Unified Modeling Language (UML) is a general-purpose, modeling language designed to provide a standard way for visualizing, specifying, constructing, and documenting the artifacts of distributed object systems. It’s the industry standard modeling language for software engineering. The aim of UML is to give software engineers, agile and small development teams, and system architects useful tools for analysis, design, and implementation of software-based systems. It also provides modeling business and similar processes. The language helps to visualize your object-oriented design and communicate with others. It offers limited use for other programming paradigms.
  • PulseAudio 12.0 release notes
    When playing videos, it's important that the audio latency is known so that the video can be synchronized accurately. PulseAudio doesn't get good latency information from the kernel with A2DP playback, which has caused A/V sync problems for many people when watching videos. Now PulseAudio makes the audio buffer in the kernel much smaller, which reduces the problem a lot.

You might already know zip,tar,7-zip, etc and you would have used all these application for your requirement. Even today also we are going to discuss about similar kind of topic, the tool name is Zstandard. It is super fast data compression tool and compression ratio is very very low. Zstd is lossless data compression algorithm developed by Yann Collet at Facebook. Due to high data compression ratio many of the popular companies and databases are using this tool.

KDE: CMake 3.12 With FreeBSD, Krita 4.1 Beta, C++/Qt

  • CMake 3.12 Update on FreeBSD
    CMake 3.12 has reached rc1. That means we’re testing the update on FreeBSD, and building lots and lots of packages. And, as I’ve written previously, every CMake update triggers a bunch of interesting software findings. As a motto, I’ve got “use it, aggressively improve it” on my website (you can hire me for odd CMake and C++ jobs, too). So hitting compile issues makes me turn to fixing software outside of KDE.

  • The day Kate Gregory enjoyed Qt
    At my company we use C++ for everything, from creating microservices to website backends and as a generator for website frontends, I mean, we do a lot of c++. And because of that we always need more c++ people, but sometimes it’s hard to find developers, but it’s easy to find php / python / javascript ones. Because of that we hired Kate Gregory’s famous c++ course – “Teaching the Teacher” to train current C++ developers to teach C++. (now, that’s a lot of ‘C++’ in a simple sentence, I know. bear with me.) For those that doens’t know, Kate Gregory is somebody that uses, advocates our beloved language even before I was born, and talks all over the world about C++ and also do trainings for companies, And so I enlisted to be her student. It was a really pleasant course going thru how to proplery explain C++ for people that know how to program but don’t know how to C++, and for that I’m grateful. But then when I commented out about Qt in the middle of the class she rolled her eyes, that made me feel a bit uneasy so I talked to her on why the eye-roll. “Qt is not c++”, and I tougth this was already settled down for years, so I asked her if she would be open to see some simple c++ code written in Qt and tell me what she thinks of it. “Well, Yes. but people already tried and it was not good”.

Red Hat: Kubernetes, 'Cloud', and GlusterFS 4.1.0 Release

  • Kubernetes StatefulSet In Action
    Recently, I stumbled upon a StackOverflow question around StatefulSets which made me wonder how well understood they are at large. So I decided to put together a simple stateful app that can be used to experiment with a StatefulSet. In this blog post we will have a closer look at this app and see it in action. If you’re not familiar with StatefulSets, now is a good time for a refresher, consulting the official docs concerning their usage and guarantees they provide.
  • The road to cloud-native applications
    As many organizations do not have the luxury of completely rebuilding their technology foundation or immediately adopting new practices and mindsets, they can embrace gradual yet fundamental shifts in culture, processes, and technology to help support greater velocity and agility. With software increasingly key to how users engage with businesses and how businesses can innovate to stay competitive, organizations should adapt to the new demands of the Digital Economy, such as speeding up application development and delivery. The cloud-native approach describes a way of modernizing existing applications and building new applications based on cloud principles, using services and adopting processes optimized for the agility and automation of cloud computing.
