  • 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.

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.

    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.

  • '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?

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.

Security: Linux 5.2 Dissection, New Patches, New ZDNet (CBS) FUD and Kali NetHunter App Store

  • Kees Cook: security things in Linux v5.2

    Gustavo A. R. Silva is nearly done with marking (and fixing) all the implicit fall-through cases in the kernel. Based on the pull request from Gustavo, it looks very much like v5.3 will see -Wimplicit-fallthrough added to the global build flags and then this class of bug should stay extinct in the kernel. That’s it for now; let me know if you think I should add anything here. We’re almost to -rc1 for v5.3!

  • Malicious Python Libraries Discovered on PyPI, Offensive Security Launches the Kali NetHunter App Store, IBM Livestreaming a Panel with Original Apollo 11 Technicians Today, Azul Systems Announces OpenJSSE and Krita 4.2.3 Released

    Offensive Security, the creators of open-source Kali Linux, has launched the Kali NetHunter App Store, "a new one stop shop for security relevant Android applications. Designed as an alternative to the Google Play store for Android devices, the NetHunter store is an installable catalogue of Android apps for pentesting and forensics". The press release also notes that the NetHunter store is a slightly modified version of F-Droid: "While F-Droid installs its clients with telemetry disabled and asks for consent before submitting crash reports, the NetHunter store goes a step further by removing the entire code to ensure that privacy cannot be accidentally compromised". See the Kali.org blog post for more details.

Ubuntu/Fedora GNOME Feud and GNOME's Sriram Ramkrishna

  • Fedora, GNOME Software, and snap

    A question about the future of package distribution is at the heart of a disagreement about the snap plugin for the GNOME Software application in Fedora. In a Fedora devel mailing list thread, Richard Hughes raised multiple issues about the plugin and the direction that he sees Canonical taking with snaps for Ubuntu. He plans to remove support for the plugin for GNOME Software in Fedora 31. There are currently two major players for cross-distribution application bundles these days: snaps, which were developed by Canonical for Ubuntu and the Snap Store, and Flatpak, which was developed by Alexander Larsson of Red Hat as part of freedesktop.org. Both systems are available for multiple Linux distributions. They are meant to give an "app-like" experience, where users simply install an application, which comes with any dependencies it has that are not provided by the snap or Flatpak runtime. The GNOME Software application has a snap plugin that, when enabled, supports the distribution, installation, and management of snaps. The Fedora project currently provides the snap plugin as a package in Fedora 30, though it is not installed by default. Hughes is the Fedora maintainer for the plugin; he announced his intention to disable the plugin since, he says, he was told that Canonical was not going to be installing GNOME Software in the next Ubuntu Long Term Support (LTS) release.

  • Molly de Blanc: Meet Sriram Ramkrishna

    Sriram Ramkrishna, frequently known as Sri, is perhaps GNOME’s oldest contributor. He’s been around the community for almost as long as it’s been around! [...] But more than that, GNOME was a project that if you think about it was audacious in its purpose. Building a desktop in 1997 around an operating system that was primitive in terms of user experience, tooling, and experience. I wanted to be part of that.

    Last week it seemed that all our limited resource machines were perpetually backlogged. I wrote yesterday to provide insight into what we run and some of our limitations. This post will be discussing the Android phones backlog last week specifically. The Android phones are hosted at Bitbar and we split them into pools (battery testing, unit testing, perf testing) with perf testing being the majority of the devices.

  • Q&A: Igniting imaginations and putting VR in the hands of students with Kai Frazier

    When you were in school, you may have taken a trip to a museum or a local park, but you probably never got to see an active volcano or watch great whites hunt. As Virtual Reality grows, this could be the way your kids will learn — using headsets the way we use computers. When you were in school, you may have gone on a trip to the museum, but you probably never stood next to an erupting volcano, watching molten lava pouring down its sides. As Virtual Reality (VR) grows, learning by going into the educational experience could be the way children will learn — using VR headsets the way we use computers. This kind of technology holds huge potential in shaping young minds, but like with most technology, not all public schools get the same access. For those who come from underserved communities, the high costs to technology could widen an already existing gap in learning, and future incomes.

Python Programming Leftovers

  • Generate a List of Random Integers in Python

    This tutorial explains several ways to generate random numbers list in Python. Here, we’ll mainly use three Python random number generation functions. These are random.randint(), random.randrange(), and random.sample(). You can find full details of these methods here: Generate random numbers in Python. All these functions are part of the Random module. It employs a fast pseudorandom number generator which uses the Mersenne Twister algorithm. However today, we’ll focus on producing a list of non-repeating integers only. Go through the below bullets to continue.

  • Gradient Boosting Classifiers in Python with Scikit-Learn

    Gradient boosting classifiers are a group of machine learning algorithms that combine many weak learning models together to create a strong predictive model. Decision trees are usually used when doing gradient boosting. Gradient boosting models are becoming popular because of their effectiveness at classifying complex datasets, and have recently been used to win many Kaggle data science competitions. The Python machine learning library, Scikit-Learn, supports different implementations of gradient boosting classifiers, including XGBoost.

    You’ve probably seen the option for Google Login on various websites. Some sites also have more options like Facebook Login or GitHub Login. All these options allow users to utilize existing accounts to use a new service. In this article, you’ll work through the creation of a Flask web application. Your application will allow a user to log in using their Google identity instead of creating a new account. There are tons of benefits with this method of user management. It’s going to be safer and simpler than managing the traditional username and password combinations. This article will be more straightforward if you already understand the basics of Python. It would also help to know a bit about web frameworks and HTTP requests, but that’s not strictly necessary.
