  • Open source XR runtime (VR/AR) 'Monado' sees a first release

    With the Khronos Group launching the OpenXR specification last year, their aim was to unify Augmented Reality (AR) and Virtual Reality (VR) development while Collabora worked on their open source implementation of Monado.

    Collabora have been hard at work on Monado, a currently Linux-focused open source XR runtime that will eventually also support other platforms. Today, they tagged the very first release. With this release they've worked in new drivers, there's now a set of scripts ready for people to try Monado rather than needing to setup a full development environment, udev rules sorted for USB permissions for XR hardware, distribution packaging and more.

    You can see the release announcement on the Collabora blog, where they note they also have some internships going. As for the code, it's all up on GitLab if you're interested in checking out in this early form. The future of XR on Linux sounds quite exciting, especially with efforts like this and Collabora do some great open source work.

  • Monado OpenXR runtime developer update

    We are very happy to tag version 0.1 of the Monado OpenXR runtime for Linux!

    Ever since announcing the project at GDC 2019, we have been working on improving the full open source XR stack to a usable state. Do keep in mind, this is a first tag, not a final release so it will contain some tinkering and is not feature complete! To echo the common phrase 'Be warned, here be dragons!'.

    Feel free to play around with Monado, and hit us up on our Discord to get help, report bugs or ask about contributing!

  • Google programming language scorecard: How C, C++, Dart, Rust, Go rate for Fuchsia

    Google has released a new programming language policy for Fuchsia, its under-development OS that some speculate could be its non-Linux successor to Android.

    Instead of a Linux kernel, the core of Google's Fuchsia OS is a Zircon microkernel to communicate with hardware and boot a system that runs Fuchsia. Google describes Fuchsia as specifically "not Linux" and a "modular, capability-based operating system".

  • Excellent Free Tutorials to Learn Prolog

    Prolog is a general purpose, declarative, logic programming language, often associated with artificial intelligence, computational linguistics, intelligent database retrieval, and problem solving. It’s widely used in research and education for natural language processing.

    Automatic backtracking is one of the most characteristic features of Prolog. It’s a form of searching, fundamental to all artificial intelligence techniques. Prolog also supports multi-directional reasoning; arguments to a procedure can freely be designated inputs and outputs in different ways in different procedure calls. This is a powerful theorem-proving technique. Another key feature of Prolog is that its syntax and semantics are closer to formal logic than say Lisp.

    Prolog is generally regarded as a difficult language to get to grips with. But learning the fundamentals of Prolog is definitely worthwhile.

  • State of DevOps Report Finds Maturity Varies Widely by Industry

    The scorecard gave the technology industry an "A" for DevOps adoption and an "A-" for security integration as part of the DevOps development pipeline. Brown noted that it was expected that companies in the technology industry would be leading the pack in terms of security integration because DevOps tends to be part of the DNA of those organizations.

Monado OpenXR Runtime v0.1 Released

  • Monado OpenXR Runtime v0.1 Released For Open-Source XR Stack

    Announced last March was Monado as an open-source implementation of OpenXR, the Khronos standard for AR/VR. Today marks the first release of Monado as version 0.1 so while it's still early on it is showing much progress.

    This open-source XR stack has added support for the Project North Star as an open-source optical see-through headset, an Intel RealSense T265 driver is also available, scripts for trying various demos, and packaging support for various Linux distributions.

  • Linux Plumbers Conference: Update on the Plumbers Covid-19 Situation

    We’re still planning to hold Plumbers, but adopting a wait and see attitude to the in-person component. As people have noticed, the global prospect for being able to travel to Halifax in August seems to be getting worse, so we’re posting this to give more transparency to what the Plumbers Conference decision points and options are. Our first consideration is a go/no-go decision point for the in-person conference. Currently, the date we were planning to put the first batch of tickets on-sale (15 May) represents the ideal date for this because it gives time (another 6 weeks) for more clarity to emerge on the situation, while avoiding people doing early purchases only to be disappointed if the event has to be cancelled at a later date.

  • AMD's Marek Olšák Lands Even More OpenGL Threading Improvements Into Mesa 20.1

    One month ago to the day I was writing about OpenGL threading improvements for Mesa 20.1 and since then more "GLTHREAD" work has materialized and successfully landed for improving the Mesa OpenGL driver performance. Longtime AMD open-source developer Marek Olšák has been leading this recent work on GLTHREAD. Over the past month he has landed various GLTHREAD optimizations and whitelisting more games to flip on "mesa_glthread" by default.

  • Building The Seq Language For Bioinformatics

    Bioinformatics is a complex and computationally demanding domain. The intuitive syntax of Python and extensive set of libraries make it a great language for bioinformatics projects, but it is hampered by the need for computational efficiency. Ariya Shajii created the Seq language to bridge the divide between the performance of languages like C and C++ and the ecosystem of Python with built-in support for commonly used genomics algorithms. In this episode he describes his motivation for creating a new language, how it is implemented, and how it is being used in the life sciences. If you are interested in experimenting with sequencing data then give this a listen and then give Seq a try!

  • qView is a minimalistic image viewer for Windows, Linux and macOS

    The program doesn't use a lot of resources when you use it normally. I did notice a memory spike viewing a slideshow of high resolution photos, it jumped from 75MB to 150MB, but that may have been due to the fact that the picture was very large in size. Otherwise, it stayed in the 70s for the most part.

  • 6 Open-Source AI Frameworks You Should Know About

    Google’s open-source framework TensorFlow is an ecosystem of tools, libraries and resources that’s used by many popular companies like Airbnb, eBay, DropBox and more. TensorFlow aims to simplify and abstract away the complexity of machine learning algorithms to streamline development. Using visual models and flowgraphs, developers and data scientists can quickly create neural networks and other machine learning models to leverage data. Airbnb, for example, is using TensorFlow to categorize apartment listing photos to ensure they accurately represent a particular space.
