  • Get 13 Linux & Programming Stickers in $1 from Unixstickers (Includes Free Shipping World Wide)

    If you’ve been collecting stickers/goodies on UNIX & other programming languages that you love, Unixstickers should not require an introduction. Italy based e-commerce, Unixstickers has been the one-stop shop for getting Linux and programming stickers, magnets, mugs and other merchandises. Unixstickers has been the official merchandise vendor for a number of open source projects and it donated part of the profit to a number of open source projects.

  • Kubernetes at 4 Years Old Continues to Improve Cloud Native Technology

    On June 6, 2014, Joe Beda published the first code commit for the open-source Kubernetes container orchestration project. Four years later, Kubernetes has become a core enabler for cloud native technology and benefits from the support of all the major public cloud providers and many major enterprise IT vendors as well.

    When Beda made the first code commit, he was an engineer at Google. In 2018, Beda is now the co-founder and CTO of Heptio, which provides commercial support and services for Kubernetes. In a video interview with eWEEK, Beda discusses the scope of Kubernetes, what it is and what it isn't as well as providing some insight into what's coming next.

  • Tracking Mesa's VirGL OpenGL Features

    It's now much easier tracking the state of VirGL that allows for OpenGL acceleration within guest virtual machines by passing on the rendering calls to the system's host OpenGL driver via Mesa and the virglrenderer library.

    VirGL has come along a lot since its debut three years ago, but even with a host OpenGL driver having OpenGL 4.5, the VirGL code and renderer library aren't yet ready for those latest OpenGL 4.x capabilities.

  • Google freezes Android P: Get your shoes on, tire-kicking devs

    With Google freezing the Android P APIs yesterday, both major mobile platforms have shown their hand for 2018. The freeze comes as Google released "Beta 2", which is really the third Developer Preview release of Android P issued so far.

    The API freeze means developers can now compile and submit apps compatible with Android P to the Google Play Store.

    This is the first year in which Google has really invited a range of enthusiasts to come in and kick the tires. Previous Android previews only ran on Google devices, but this year a number of other devices - from Nokia, Sony, Xiaomi, OnePlus, Essential and Vivo - can also get a glimpse of code before it is baked into manufacturers' ROMs. These images will be pushed out shortly.

Programming: C++, Python and In-house OpenJDK Implementation of Alibaba

  • Next C++ workshop: Pointers and Linked Lists, 28 March at 19:00 UTC
    Another workshop is coming up! Improve your C++ skills with the help of LibreOffice developers: we’re running regular workshops which focus on a specific topic, and are accompanied by a real-time IRC meeting. For the next one, the topics are Pointers and Linked Lists. Start by watching this presentation:
  • Python programming language: Pyboard D-series arrives for MicroPython robots
    The new Pyboard D-series micro-controller is now available for purchase at a rather hefty price of £43 ($56), offering developers a low-powered device for running programs created with MicroPython, a stripped-back version of the hugely popular Python 3 programming language.
  • Commenting Python Code
    Programming reflects your way of thinking in order to describe the single steps that you took to solve a problem using a computer. Commenting your code helps explain your thought process, and helps you and others to understand later on the intention of your code. This allows you to more easily find errors, to fix them, to improve the code later on, and to reuse it in other applications as well. Commenting is important to all kinds of projects, no matter whether they are - small, medium, or rather large. It is an essential part of your workflow, and is seen as good practice for developers. Without comments, things can get confusing, real fast. In this article we will explain the various methods of commenting Python supports, and how it can be used to automatically create documentation for your code using the so-called module-level docstrings.

  • Alibaba Dragonwell8 : The In-house OpenJDK Implementation At Alibaba
    Alibaba requires no introduction. It is one of the popular and largest multinational conglomerate founded by Jack Ma, a business magnate and philanthropist from China. It is also world’s fifth-largest internet company by revenue. It specializes in various sectors such as e-commerce, retail, Internet and technology. Alibaba team has provided significant contribution to open source projects. One such project is OpenJDK. The development team at Alibaba has developed many Java-based applications over the years. They have adopted OpenJDK and created their own JDK named “Alibaba Dragonwell8”. It is the downstream version of OpenJDK and completely open source. Alibaba Dragonwell is optimized for developing e-commerce, financial, logistics applications which are running on their 100k+ servers. It is certified as compatible with the Java SE standard. It is currently supports Linux/x86_64 platform only. Let us hope they will extend the support to Unix and other platforms soon. In this guide, we will see how to install Alibaba Dragonwell8 in Linux. I have tested this guide on Ubuntu 18.04 LTS server. However, it should work on other Linux distributions as well.

Why We Need Our Nonprofits

SPARC was at best a relatively small success. But RISC did succeed, massively, with ARM (which stands for Advanced RISC Machine). ARM started as the Acorn RISC Machine in 1983. Today, most of the world's mobile devices run ARM chips. I don't know how well the CHIPS Alliance will do, but I do know that only an entity big and experienced enough to pull giant competing companies together can do it. For Linux, that's the Linux Foundation. I'm glad we have it. I'm also glad we have the Software Freedom Conservancy. Times are getting tough for FLOSS, and we need all the help we can get. Read more

See GNOME 3.32 on Ubuntu 19.04 Beta

Although the 19.04 is still not officially released this March, but even today we can download the development version and run it (LiveCD) on our computer. We find that it includes the 3.32, the latest version of GNOME desktop environment. I want to highlight some interesting aspects of it on Ubuntu as we saw it on Fedora Rawhide few days ago. I suggest you to download the 19.04 daily-live ISO and quickly test it, I believe you can feel the performance improvements especially how quick it's now to open the start menu and it's now even quicker to search files on Nautilus. Here we go. Happy testing! Read more
