  • Unreal Engine 4.21 Released

    Unreal Engine 4.21 continues our relentless pursuit of greater efficiency, performance, and stability for every project on any platform. We made it easier to work smarter and create faster because we want your imagination to be the only limit when using our tools. And we battle-tested the engine on every platform until it met our developers' high standards so your project will shine once it is ready for the masses.

    We are always looking for ways to streamline everyday tasks so developers can focus on creating meaningful, exciting, and engaging experiences. Our industry-leading Niagara effects toolset is now even more powerful and easier to use, enabling you to dream up the next generation of real-time visual effects. You can build multiplayer experiences on a scale not previously possible using the now production-ready Replication Graph functionality. Iterate faster thanks to optimizations with up to a 60% speed increase when cooking content, run automated tests to find issues using the new Gauntlet automation framework, and speed up your day-to-day workflows with usability improvements to the Animation system, Blueprint Visual Scripting, Sequencer, and more.

    We strive to make it possible for your creations to be enjoyed as you intended by everyone, everywhere regardless of the form factor they choose. Building on the previous release, we have added even more optimizations developed for Fortnite on Android and iOS to further improve the process for developing for mobile devices. Available in Early Access, Pixel Streaming opens a whole new avenue to deploy apps in a web browser with no barrier to entry and no compromise on rendering quality. We have also improved support for Linux as well as augmented, virtual, and mixed reality devices.

  • Unreal Engine 4.21 Released, Linux Now Defaults To Vulkan

    Unreal Engine 4.21 is out today as the last feature release for Epic Games' engine of 2018. This is an exciting game engine update for Linux and Vulkan fans.

    Unreal Engine 4.21 features various tooling and creation improvements for game developers, optimizations that come to the engine following Epic's development of Fortnite for iOS and Android, performance enhancements, early access pixel streaming support, animation system optimizations, and more.

  • Unreal Engine 4.21 is out, now defaults to the Vulkan API on Linux

    Epic Games have released Unreal Engine 4.21 and it includes some interesting stuff on the Linux side of things.

    From now, Unreal Engine will default to using the Vulkan API on Linux and fallback to OpenGL when that can't be used. This is going to be good for the future of Linux games, since it should help developers get better performance.

    On top of that, it features a new media player for Linux with the bundled WebMMedia plugin which includes support for WebM VPX8/9 videos. To further improve Linux support, they now have a proper crash reporter interface so that they can "continue to improve support for Linux platforms".

OSS Leftovers

  • The Power Of Open Source AI
    he open source software movement produced iconic innovations like the Firefox web browser, Apache server software and the Linux operating system—the genesis of the Android OS that currently powers 86% of the world’s smartphones. It also fostered a mindset around continuous improvement of tools that can be collaboratively shared, improved upon and distributed.
  • Apache Dubbo, the Java-based open source RPC framework becomes a Top-Level Project
    The Apache Software Foundation announced that the Java-based open source RPC framework used by giants like Alibaba, Apache Dubbo, is now a Top-Level Project. Let’s have a look at what this framework is all about. Apache Dubbo is a high-performance, Java-based Remote Procedure Call framework that has been in use at more than 150 companies, including giants like Alibaba Group or the Industrial and Commercial Bank of China. The Dubbo project was originally developed at Alibaba and open-sourced in 2011. It entered the Apache Incubator in February 2018 and the Apache Software Foundation announced that Dubbo is now a Top-Level Project!
  • Bridging divides with open source
    Application delivery is changing. At the risk of using buzzwords, it is being transformed – digitally. Continuous delivery has become the norm for DevOps (71 per cent plan on implementing, according to a study conducted by F5 and RedHat – NetOps Meets DevOps: The State of Network Automation), and continuous deployment must follow if business is to succeed in the era of Application Capital. While 73 per cent of organisations plan on pursuing continuous deployment, nearly half of them have yet to begin. A staggering 42 per cent have yet to automate a single component of the continuous deployment pipeline (according to a study conducted by F5 and RedHat – NetOps Meets DevOps: The State of Network Automation). [...] Applications themselves are mainly developed today from third-party components, a majority of them open source. Application infrastructure is increasingly built from open source components. From web servers to app servers, databases to ingress control, messaging to container runtimes and orchestration. IT operations are driven by open source tools like Puppet, Chef, Terraform, Helm, Kubernetes, and Ansible. These technologies are adopted because they answer multiple challenges: fast, frequent delivery and deployment along with a frictionless business model. They also encourage collaboration and innovation when entire organisations move to standardise on open source-based operations. None of that is possible without the passionate communities of developers who work tirelessly to improve their open source solutions. At F5, we appreciate the value of such communities. In a comparable example, our DevCentral community is based on collaborative innovation, guided by many of the same principles that drive open source projects. Code sharing and knowledge transfers across the community help the hundreds of thousands of members innovate and create new capabilities for our BIG-IP platform. With those solutions come new extensions, plug-ins, and libraries for open source projects like Puppet and Chef and node.js.

The technology, called Drop-seq, is a method for measuring the RNA present in individual cells, allowing scientists to see what genes are being expressed and how this relates to the specific functions of different cell types …. [T]he freely shared protocol had previously only been used in animal cells.

Open Hardware: Adafruit Feather and Stanford Doggo

  • Feather Plus Blackberry Equals Open Source Fauxberry
    The keyboard is a superior means of input, but to date no one has really figured out how to make a keyboard for small, handheld electronics. You could use tact switches, but that’s annoying, or you could use a touch screen. The best option we’ve seen is actually a Blackberry keyboard, and [arturo182] has the best example yet. It’s a small handheld device with a screen, keyboard, and WiFi that’s ready to do anything imaginable. Think of it as an Open Source Fauxberry. In any case, we want it. This project is actually a breakout board of sorts for the Adafruit Feather system, and therefore has support for WiFi, cellular, or pretty much any other networking of connectivity. To this blank canvas, [arturo] added an accelerator/magnetometer sensor, a single Neopixel, and of course the beautiful Blackberry keyboard. This keyboard is attached to an ATSAMD20G, a microcontroller with a whole bunch of I/O that translates key presses into I2C for the Feather.
  • Students from Stanford's Robotics Club Releases Open-Source Robo-Dog Online
    Robotics isn't cheap by any means, and no one knows this better than the students of the Extreme Mobility Team of Standford University's Robotics Club (SEMT). The materials used by university robotics clubs can cost upwards of tens of thousands of dollars, making it that much harder for many high schools and less well-funded colleges and universities to invest heavily in this important field of research.
  • Watch this open-source dog robot do backflips [Ed: This is more likely to be used in military rather than in aeronautics and astronautics (luxury of the rich)]
    “We’re hoping to provide a baseline system that anyone could build,” says Patrick Slade, graduate student in aeronautics and astronautics and mentor for Extreme Mobility.
  • Meet Doggo: Stanford’s cute open-source four-legged robot
    Doggo follows similar designs to other small quadrupedal robots, but what makes it unique is its low cost and accessibility. While comparable bots can cost tens of thousands of dollars, the creators of Doggo — Stanford’s Extreme Mobility lab — estimate its total cost to be less than $3,000. What’s more, the design is completely open source, meaning anyone can print off the plans and assemble a Doggo of their very own.
  • Stanford Students Built This Adorable, Bouncy, Open-Source Robot Dog
    Nearly all of the parts used to create Doggo were bought intact through the internet, while the rest can be easily 3D-printed. The total costs involved in building Doggo—including shipping and handling—amounted to less than $3,000, Kau and his team claim. Via the website Github, the team has also released all of the relevant information you would need to create your Doggo, including software coding, supply list, and manual instructions. From there, any enterprising roboticist could tweak the design to create an even more capable Doggo.

Programming: JavaScript, Perl, Python and C++

  • SD Times Open-Source Project of the Week: Knockout
    This week’s open-source project is Knockout (KO) and it works purely on JavaScript. KO is a JavaScript MVVM (a modern variant of MVC) library that enables developers to create rich, desktop-like user interfaces with JavaScript and HTML. KO uses “observers” that help the UI stay in sync with an underlying data model and declarative bindings to enable productive development, according to Knockout’s page on GitHub.
  • Why I love Perl 6

    love Perl 6 because, if that solution seems too scary to you (too infinite, too lazy, too concurrent, too pipelined, too Unicoded, too declarative, too functional, too much like something that an Erlang guru would code), then Perl 6 will equally allow you to write a plain and simple version: one that's imperative, iterative, block structured, variable-driven, pure ASCII, and more-or-less exactly what you'd write in Perl 5, or even in C: [...]
