    GOL itself is now seven and a half years old, and hopefully we will be around for another seven at least!

  • Godot Continues Major Work On Its 3D Renderer For Release In 2017

    Open-source game engine Godot has been working on a multi-month project to vastly improve (and largely rewrite) its 3D renderer to make it as great as its 2D renderer. This work is being done for the Godot 3.0 engine and so far this 3D renderer is seeing a lot of movement.

    Godot 3.0 is aiming for a modern, clustered renderer that supports graphics features similar to other modern game engines like a physically based renderer, global illumination, shadow mapping, and more.

  • Intel's Clear Linux Is Working On Steam Support

    For those planning to do Linux gaming with Intel graphics hardware, you might soon have a new choice with the performance-oriented Clear Linux distribution out of Intel's Open-Source Technology Center.

    Clear Linux developers are currently working on bringing up support for Steam in Clear Linux, something that isn't trivial to do as the operating system tends to be 64-bit focused while Steam still depends upon a mess of 32-bit packages, among other challenges. But Intel developer Arjan van de Ven has shared a photo on Twitter showing the basics of Steam appearing to work on Clear Linux.

  • Former Valve Developer: Steam Linux Project Was The Hardest

    Getting games on Linux and improving OpenGL drivers was the hardest challenge one veteran game developer has come across.

    Rich Geldreich who had worked at Valve for five years shared the most difficult work he's done: Steam for Linux. That's on top of his time at Valve he worked at Microsoft, served as an adjunct professor, was a head researcher for a company since acquired by Google, was CTO for a mobile games company, formerly a principal software engineer at Unity, now an independent consultant / software engineer, and an expert on data compression.

Early Benchmarks Of Linux 4.10 Show Some Improvements & Regressions For Core i7-6800K

Linux

This New Year's Eve I finished up some benchmarks of the Linux 4.5 through Linux 4.10 Git kernels on a powerful Core i7 6800K "Broadwell-E" system. I found some improvements with 4.10 Git, but there are also some evident regressions.

I'll have more benchmark results in the New Year as time allows and the 4.10 development settling down, but from the tests I did so far on the Core i7 6800K system there is some concern over what appears to be some definite and noticeable regressions.

  • Skylake Iris Pro Graphics: Ubuntu, Fedora, openSUSE, Antergos, Clear Linux Benchmarks

    For those craving some more end-of-year Linux distribution benchmarks, this morning I finished carrying out a fresh Linux distro comparison focusing upon the Intel OpenGL performance when making use of "Skylake" Iris Pro hardware. For this New Year's Eve benchmarking fun was Ubuntu, Fedora, openSUSE, Antergos, and Clear Linux.

  • Mesa Saw More Than 10,000 Commits This Year From Record Number Of Contributors

    Unless Marek delivers another one of his big patch-sets to provide some new feature/improvement to RadeonSI, the OpenGL shader cache magically lands, or some other big surprise to end out the year, here are some final statistics about Mesa's impressive developments in 2017.

  • AVC VDENC Video Encoding Enabled For Intel Broxton & Kabylake

    For those that don't recall, VDENC is a low-power, high-performance video encode engine added originally to Intel Skylake hardware. That aforelinked article covers the big benefits of using VDENC and the patches published earlier this year for enabling this Intel video encode engine on Linux.

Germany's 1&1 Still Working On MARS For The Linux Kernel, Still Hoping For Upstream

Linux

At the end of last year was an update on MARS Replication System Still Being Worked On For Upstream Linux Kernel and like clock work, the German web hosting provider has issued another update on the in-development MARS replication system and is still hoping to mainline it, maybe next year.

MARS' tag-line at the 1&1 web hosting company is "replicating petabytes over long distances" and "has replaced DRBD as the backbone of the 1&1 geo-redundancy feature as publicly advertised for 1&1 Shared Hosting Linux (ShaHoLin). MARS is also running on several other 1&1 clusters. Some other people over the world have also seemingly started to use it."

  • 7 New Year’s Resolution Ideas for Open Source Project Developers

    It seems like only yesterday that 2016 begun and we were just about to see great changes happening with SourceForge. Now we’re at the end of it, readying ourselves for yet another year.

    As fond as we are of the year that was, now is not just a time for remembering “Auld Lang Syne”, but also a time to prepare for what comes next. For open source project developers that means not only reflecting upon decisions and actions made, but also coming up with new resolutions that will define the future of open source projects.

  • Business model as a variable to consider when choosing Open Source software.

    Any analytic report about who writes the code in open and collaborative environments will reflect how corporations involvement is increasing in Open Source software development at every level. More and more companies are transitioning from becoming FLOSS consumers to producers and almost every new software company out there has Open Source as a core strategy or even as part of their DNA.

    But who is sustaining the development of that key piece of software that will be a core part of your future product? Who pays those developers? Why? How does the key stakeholders benefit from the outcome of the ecosystem and the software they produce? How much do they invest in the production of that software? For how long? How do they get their income? What is the relevance of the software produced by the ecosystem they feed in their business models?

    These and similar basic questions need to be fully understood before a specific software becomes part of your key product or business. Knowing the answers to the above questions might not prevent you from surprises in the future but at least can prepare you for the potential consequences. What it is clear to me is that these answers are becoming more complicated to find and understand over time, specially for those companies who do not have a strong background on Open Source.

    Choosing a specific piece of software based on purely technical variables or even present healthiness of the community around the project/organization, expectations of the number of contributors or impact in general might not be enough any more. A specific community or project will become "your provider" so the business model behind it is equally important.

  • Open source down under: Linux.conf.au 2017

    It’s a new year and open source enthusiasts from around the globe are preparing to gather at the edge of the world for Linux.conf.au 2017. Among those preparing are Googlers, including some of us from the Open Source Programs Office.

  • Firefox 52 Borrows One More Privacy Feature from the Tor Browser

    Mozilla engineers have added a mechanism to Firefox 52 that prevents websites from fingerprinting users using system fonts.

    The user privacy protection system was borrowed from the Tor Browser, where a similar mechanism blocks websites from identifying users based on the fonts installed on their computers.

    The feature has been active in the Tor Browser for some time and will become active in the stable branch of Firefox 52, scheduled for release on March 7, 2017.

    The font fingerprinting protection is already active in Firefox 52 Beta.

  • Hungary withdraws membership from Open Government Partnership

    Hungary has decided to withdraw its membership from the OGP, following a disagreement with the OGP Steering Committee on a report.

  • Scotland published its first action plan as OGP “Pioneer“

    Scotland published its first Open Government National Action Plan since it has been selected by the Open Government Partnership (OGP) as one of the fifteen “Pioneer” governments in April 2016.

  • Germany and Luxembourg joined OGP

    During the Paris OGP Summit 2017, Germany and Luxembourg were among the European countries that announced their intent to join the Open Government Partnership. Portugal said it will “soon” become a member of the institution.

  • Contracting 5 initiative officially launched at Paris OGP Summit
  • OGP countries shifting commitments from basics to innovations

    The countries participating in the Open Government Partnership (OGP) are shifting their attention from "getting the basics right" to innovative measures and reforms that translate into actions capable of generating real change. After 'public service delivery', the areas 'fiscal openness' and 'access to information' are the most prevailing in the commitments for 2015-2016.

  • Paris Declaration to promote collective actions in open government

    The Paris Declaration, which was presented at the OGP Paris Summit in December, will encourage cooperation between countries and civil societies to promote open government on a global scale. The Declaration lists twenty-one collective actions in which governments can take part and share experiences. “Actions are concrete cooperation, output-orientated and will produce tangible results”, the text of the Declaration states.

  • French to test Sirene data in a hackathon

    Etalab, the French agency in charge of Open Data in France, and INSEE (Institut National de la Statistiques et des Etudes Economiques) – the French national agency for statistics, organised in November a hackathon to test and use the data of the SIRENE (Système informatique pour le répertoire des entreprises et des établissements) database which will be published as open data in January.

  • 'Open Source' Robo-Car in '17?

    The year 2016 opened the door to a new phase of highly automated driving, moving the discussion away from “wouldn’t it be nice-to-have-a-robo-car” to a more immediate “to-do list” with which regulators, car OEMs and technology companies must grapple if they hope to make self-driving cars commercially viable and safe.

    Gone are days of early-adapter giddiness over the Google car, or an “Autopilot” Tesla with over-the-air software upgrades.

    Reality sank in 2016. The industry is now aware Autopilot’s limitations. The automotive engineering community is taking a crash course in Artificial Intelligence (AI) that’s far beyond today’s computer vision. Engineers are taking note of challenges in machine learning (how do you certify the safety of AI-driven cars?). Many automakers are scrambling for a holistic approach toward cybersecurity.

    So, what’s in the auto industry 2017 agenda that could change the course of robotic car development?

  • Washington Post Publishes False News Story About Russians Hacking Electrical Grid

    A story published by The Washington Post Friday claims Russia hacked the electrical grid in Vermont. This caused hysteria on social media but has been denied by a spokesman for a Vermont utility company.

    The Post story was titled, “Russian hackers penetrated U.S. electricity grid through a utility in Vermont, officials say.”

  • Recount 2016: An Uninvited Security Audit of the U.S. Presidential Election

    The 2016 U.S. presidential election was preceded by unprecedented cyberattacks and produced a result that surprised many people in the U.S. and abroad. Was it hacked? To find out, we teamed up with scientists and lawyers from around the country—and a presidential candidate—to initiate the first presidential election recounts motivated primarily by e-voting security concerns. In this talk, we will explain how the recounts took place, what we learned about the integrity of the election, and what needs to change to ensure that future U.S. elections are secure.

Linux

It is time for the final vote. I have already given you my opinion on the finest performers when it comes to individual desktop environments - Plasma, Xfce and even Gnome, but now, following in the best of our annual traditions, we need to vote on the most complete, most successful distribution of the year.

Unlike the desktop environment votes, it will not be purely based on the final score. I will also incorporate other elements - how deeply has a particular distro charmed me, whether I have continued using it after the initial review, how it has evolved, and of course, the critical stability, support and friendliness parameters. And then, there's your vote, too. So let's run through the coveted shortlist. To wit, the 2016 elite.

  • Deliverable 1 : [✓]
    Seems okay, far better than the initial results. Although I should say, I deviated from what I thought I would need to write. First I assumed that I don’t have to write another boost::graph wrapper for KisPaintDevice, but I had to. That was one heck of an experience. In one of the last few posts, I ranted on Dmitry’s interpretation of the Graph, turns out we were on the same page but I understood his explanation the wrong way. I should put more attention to details from now on I guess. All the pixels are connected to each other, but they only have an edge between them if they are adjacent. If in center, the out degree would be 8, if in corners, 3 and if in edges, 5. There are some other cases too, but I will leave them for the moment. While writing the wrapper, I also got to know some of the cool features and techniques of C++, which I will be writing posts on as soon as I get some time, concepts, traits, avoiding virtual functions and what not. It is commendable that how boost approaches boost::astar_search, there is not a single virtual function, you don’t have to inherit anything (you can though for safety), just templates and traits, you are done.
  • Go Creeping In
    I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between, there are oceans and oceans of Java; to a remarkable degree, it runs the Internet. Except for, here and there, you find a small but steadily increasing proportion of Go.
  • Stand by for FPR14 SPR1 chemspill
    Mozilla has shipped a fix for MFSA2019-18 in Firefox 67.0.3 and 60.7.1. This exploit has been detected in the wild, and while my analysis indicates it would require a PowerPC-specific attack to be exploitable in official TenFourFox builds (the Intel versions may be directly exploited, however), it could probably cause drive-by crashes and we should therefore ship an urgent fix as well. The chemspill is currently undergoing confidence tests and I'm shooting to release builds before the weekend. For builders, the only change in FPR14 SPR1 is the patch for bug 1544386, which I will be pushing to the repo just as soon as I have confirmed the fix causes no regressions.

All Linux, all the time: Supercomputers Top 500

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux. Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight. When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores. And, what do all these processors run? Linux, of course. . 133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed. Read more

  • Are DevOps certifications valuable? 10 pros and cons
  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.
  • Red Hat named HPE’s Partner of the Year at HPE Discover 2019
    For more than 19 years, Red Hat has collaborated with HPE to develop, deliver and support trusted solutions that can create value and fuel transformation for customers. Our work together has grown over these nearly two decades and our solutions now include Linux, containers and telecommunications technologies, to name just a few. As a testament to our collaboration, HPE has named Red Hat the Technology Partner of the Year 2019 for Hybrid Cloud Solutions.
  • Demystifying Containers – Part II: Container Runtimes
    This series of blog posts and corresponding talks aims to provide you with a pragmatic view on containers from a historic perspective. Together we will discover modern cloud architectures layer by layer, which means we will start at the Linux Kernel level and end up at writing our own secure cloud native applications. Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.
  • Edge > Core > Cloud: Transform the Way You Want
    For more than 25 years, SUSE has been very successful in delivering enterprise-grade Linux to our customers. And as IT infrastructure has shifted and evolved, so have we. For instance, we enabled and supported the move to software-defined data centers as virtualization and containerization technologies became more prevalent and data growth demanded a new approach.
  • SUSE OpenStack Cloud Technology Preview Takes Flight
    We are pleased to announce that as of today we are making a technology preview of a containerized version of SUSE OpenStack Cloud available that will demonstrate a future direction for our product. The lifecycle management for this technology preview is based on an upstream OpenStack project called Airship, which SUSE has been using and contributing to for some time. This follows our open / open policy of upstream first and community involvement.
