  • 4 Useful Cinnamon Desktop Applets

    The Cinnamon desktop environment is incredibly popular, and for good reason. Out of the box it offers a clean, fast and well configured desktop experience.

    But that doesn’t mean that you can’t make it a little better with a few nifty extras.

    And that’s where Cinnamon Applets come in. Like Unity’s Indicator Applets and GNOME Extensions, Cinnamon Applets let you add additional functionality to your desktop quickly and easily.

  • GNOME Core Apps Hackfest

    The hackfest is aimed to raise the standard of the overall core experience in GNOME, this includes the core apps like Documents, Files, Music, Photos and Videos, etc. In particular, we want to identify missing features and sore points that needs to be addressed and the interaction between apps and the desktop.

    Making the core apps push beyond the limits of the framework and making them excellent will not only be helpful for the GNOME desktop experience, but also for 3rd party apps, where we will implement what they are missing and also serve as an example of what an app could be.

  • Top 5 Reasons to Love Kubernetes

    At LinuxCon Europe in Berlin I gave a talk about Kubernetes titled "Why I love Kubernetes? Top 10 reasons." The response was great, and several folks asked me to write a blog about it. So here it is, with the first five reasons in this article and the others to follow. As a quick introduction, Kubernetes is "an open-source system for automating deployment, scaling and management of containerized applications" often referred to as a container orchestrator.

  • Website-blocking attack used open-source software

    Mirai gained notoriety after the Krebs attack because of the bandwidth it was able to generate — a record at well over 600 gigabits a second, enough to send the English text of Wikipedia three times in two seconds. Two weeks later, the source code for Mirai was posted online for free.

  • Alibaba’s Blockchain Email Repository Gains Technology from Chinese Open Source Startup

    Onchain, an open-source blockchain based in Shanghai, will provide technology for Alibaba’s first blockchain supported email evidence repository.

    Ali Cloud has integrated Onchain’s Antshares blockchain technology to provide an enterprise-grade email repository. Onchain provides the bottom-layer framework for Ali Cloud, including its open-source blockchain capabilities, to enable any company to customize its own enterprise-level blockchain.

  • Netflix on Firefox for Linux

    If you're a Firefox user and you're a little fed up with going to Google Chrome every time in order to watch Netflix on your Linux machine, the good news is since Firefox 49 landed, HTML5 DRM (through the Google Widevine CDM (Content Decryption Manager) plugin) is now supported. Services that use DRM for HTML5 media should now just work, such as Amazon Prime Video. Unfortunately, the Netflix crew haven't 'flicked a switch' yet behind the scenes for Firefox on Linux, meaning if you run Netflix in the Mozilla browser at the moment, you'll likely just come across the old Silverlight error page. But there is a workaround.

    For some reason, Netflix still expects Silverlight when it detects the user is running Firefox, despite the fact that the latest Firefox builds for Linux now support the HTML5 DRM plugin.

  • Study: Administrations unaware of IT vendor lock-in

    Public policy makers in Sweden have limited insight on how IT project can lead to IT vendor lock-in, a study conducted for the Swedish Competition Authority shows. “An overwhelming majority of the IT projects conducted by schools and public sector organisations refer to specific software without considering lock-in and different possible negative consequences”, the authors conclude.

  • How open access content helps fuel growth in Indian-language Wikipedias

    Mobile Internet connectivity is growing rapidly in rural India, and because most Internet users are more comfortable in their native languages, websites producing content in Indian languages are going to drive this growth. In a country like India in which only a handful of journals are available in Indian languages, open access to research and educational resources is hugely important for populating content for the various Indian language Wikipedias.

  • Where to find the world's best programmers

    One source of data about programmers' skills is HackerRank, a company that poses programming challenges to a community of more than a million coders and also offers recruitment services to businesses. Using information about how successful coders from different countries are at solving problems across a wide range of domains (such as "algorithms" or "data structures" or specific languages such as C++ or Java), HackerRank's data suggests that, overall, the best developers come from China, followed closely by Russia. Alarmingly, and perhaps unexpectedly, the United States comes in at 28th place.

  • AtScale Delivers Findings on BI-Plus-Hadoop

    Business intelligence is the dominant use-case for IT organizations implementing Hadoop, according to a report from the folks at AtScale. The benchmark study also shows which tools in the Haddop ecosystem are best for particular types of BI queries.

    As we've reported before, tools that demystify and function as useful front-ends and connectors for the open source Hadoop project are much in demand. AtScale, billed as “the first company to allow business users to do business intelligence on Hadoop,” focused its study on the strengths and weaknesses of the industry’s most popular analytical engines for Hadoop – Impala, SparkSQL, Hive and Presto.

  • Study Says OpenStack at Scale Can Produce Surprising Savings

    Revenues from OpenStack-based businesses are poised to grow by 35 percent a year to more than $5 billion by 2020, according to analysts at 451 Research. In its latest Cloud Price Index, 451 Research analyzes the costs associated with using various cloud options to determine when it becomes better value to use a self-managed private cloud instead of public or managed cloud services.

    The idea is to createa complex pricing model that takes into consideration the major factors impacting total cost of ownership (TCO), including salaries and workload requirements.The 451 study found that because of the prevalence of suitably qualified administrators, commercial private cloud offerings such as VMware and Microsoft currently offer a lower TCO when labor efficiency is below 400 virtual machines managed per engineer. But where labor efficiency is greater than this, OpenStack becomes more financially attractive. In fact, past this tipping point, all private cloud options are cheaper than both public cloud and managed private cloud options.

  • How OpenStack mentoring breaks down cultural barriers

    Victoria Martinez de la Cruz is no stranger to OpenStack's mentorship opportunities. It's how she got her own start in OpenStack, and now a few years later is helping to coordinate many of these opportunities herself. She is speaking on a panel on mentoring and internships later this week at OpenStack Summit in Barcelona, Spain. In this interview, we catch up with Victoria to learn more about the details of what it's like to be a part of an open source internship, as well as some helpful advice for people on both sides of the mentoring process.

  • Intrinsic Is A Promising, Open-Source, Cross-Platform Vulkan Game Engine

    Ever hear of the Intrinsic game engine? Neither have we, until The Khronos Group mentioned it this morning as a new game engine focused on Vulkan support that was open-sourced last week.

    Intrinsic is an open-source cross-platform graphics and game engine that's designed around Vulkan. Intrinsic is still in the early stages of development but the visuals from it so far appear quite good. The game engine is actually GPLv3 licensed but the developer is also making it available for proprietary purposes through private means.

And today, we're able to test drive the second RC build, which introduces even more bug fixes and improvements.

  • LLGL Aims To Be Abstraction Layer For OpenGL, Direct3D 11/12 & Vulkan

    One of my "hobbies" when news is light and there isn't any fun/new/exciting hardware keeping me busy on a given weekend is checking out the various Vulkan projects on GitHub. It's been great seeing all of the independent graphics renderers/engines being tried by different individuals, tons of different Vulkan samples, and a lot of other innovative projects around Vulkan, many of which I've written about in the past few months on Phoronix. One of the projects I see being regularly updated when checking on weekends and haven't written about yet is LLGL, the Low-Level Graphics Library.

  • Spark on Kubernetes at Spark Summit EU

    I’ll be speaking about Spark on Kubernetes at Spark Summit EU this week. The main thesis of my talk is that the old way of running Spark in a dedicated cluster that is shared between applications makes sense when analytics is a separate workload. However, analytics is no longer a separate workload — instead, analytics is now an essential part of long-running data-driven applications. This realization motivated my team to switch from a shared Spark cluster to multiple logical clusters that are co-scheduled with the applications that depend on them.
