tuxmachines.org - Tor, 12/11/2018 - 23:04
  • The Linux Direct Rendering Manger Subsystem Poised To Have A Second Maintainer

    For hopefully helping out with code reviews and getting code staged in a timely manner before being upstreamed to the mainline Linux kernel, Daniel Vetter of the Intel Open-Source Technology Center is set to become a co-maintainer. 

    Daniel Vetter who has been with Intel OTC for a number of years working on their Linux graphics driver has proposed becoming a DRM co-maintainer, "MAINTAINERS: Daniel for drm co-maintainer...lkml and Linus gained a CoC, and it's serious this time. Which means my [number one] reason for declining to officially step up as drm maintainer is gone, and I didn't find any new good excuse."

    The Python Standard Library is like a gold mine, and the pathlib module is really a gem.

  • QtCreator CMake for Android plugin

    It’s about QtCreator CMake for Android! I know it’s a strange coincidence between this article and The Qt Company’s decision to ditch QBS and use CMake for Qt 6, but I swear I started to work on this project *before* they announced it ! This plugin enables painless experience when you want to create Android apps using Qt, CMake and QtCreator. It’s almost as easy as Android Qmake QtCreator plugin! The user will build, run & debug Qt on Android Apps as easy as it does with Qmake.

  • Processing CloudEvents with Eclipse Vert.x

    Our connected world is full of events that are triggered or received by different software services. One of the big issues is that event publishers tend to describe events differently and in ways that are mostly incompatible with each other.

    To address this, the Serverless Working Group from the Cloud Native Computing Foundation (CNCF) recently announced version 0.2 of the CloudEvents specification. The specification aims to describe event data in a common, standardized way. To some degree, a CloudEvent is an abstract envelope with some specified attributes that describe a concrete event and its data.

  • Mozilla Firefox 64 Now Available for Download on Windows, Linux, and macOS

    Mozilla has just released Firefox 64 stable for users on Windows, Linux, and macOS, with the Android version likely to be updated in the coming hours.
    While checking for updates using the built-in update engine may not offer you Firefox version 64, you can download the browser using the links below, as Mozilla has just updated its servers with the new builds.

    Firefox 64 introduces a series of changes that were previously tested as part of the beta versions, including recommended extensions. This feature is supposed to help improve the experience with the browser by providing suggestions on services that are relevant to your activity.

  • Microsoft vs the web

    I have been saying for a few years now that Chrome is the new IE, and the Google is the new Microsoft (Microsoft being the new IBM). This statement have been somewhat tongue in cheek, but I have always been serious about it not being a joke: history is repeating. I could got at length on all the reasons why I believe this to be true, but I’ll just talk about one new development.

    Last week, Microsoft announced that they had decided to abandon EdgeHTML, their web browser engine, and move to be using Google’s Chromium as the heart of the web browser offering, Edge. [1] Whether it will be just Blink and V8 (Web rendering and JS engine respectively) or also parts of Chromium is something unclear.

  • What is Chromium and why is Microsoft using it for Edge?

    Chromium is very similar. You can install a standalone application for Windows, macOS and any flavor of Linux named Chromium that's a complete web browser complete with synchronization through Google's could services. But Chromium is also the name of the open-source code project used to make Chromium, as well as the Chrome web browser, Chrome OS, Amazon Silk, and the Android Chrome web-view component companies like Twitter can use to build a browser into an application.

Firefox 64 released

LWN.net - Tor, 12/11/2018 - 20:49
The Mozilla Blog takes a look at the Contextual Feature Recommender (CFR) in Firefox 64. "Aimed at people who are looking to get more out of their online experience or ways to level up. CFR is a system that proactively recommends Firefox features and add-ons based on how you use the web. For example, if you open multiple tabs and repeatedly use these tabs, we may offer a feature called “Pinned Tabs” and explain how it works. Firefox curates the suggested features and notifies you. With today’s release, we will start to rollout with three recommended extensions which include: Facebook Container, Enhancer for YouTube and To Google Translate. This feature is available for US users in regular browsing mode only. They will not appear in Private Browsing mode. Also, Mozilla does NOT receive a copy of your browser history. The entire process happens locally in your copy of Firefox." The release notes contain more details about this release.

An Initial Look At The Intel Iris Gallium3D Driver Performance

tuxmachines.org - Tor, 12/11/2018 - 20:45

One of the most exciting developments in the open-source Intel driver space this year was the Iris Gallium3D driver taking shape as what's destined to eventually succeed their "classic" i965 Mesa driver. With Iris Gallium3D maturing, here's a look at how the performance currently stacks up to their mature OpenGL driver.

The Intel Iris Gallium3D driver is designed for Skylake (potentially Broadwell too) support and newer generations while being a forward-looking driver and utilizes their mature NIR compiler support. Iris holds much more performance potential than their classic Mesa driver albeit the developers haven't really taken to performance optimizations yet but rather getting the driver up and running, eliminating test suite failures, and getting to the point of feature parity with the i965 driver.

[$] Large files with Git: LFS and git-annex

LWN.net - Tor, 12/11/2018 - 20:43

Git does not handle large files very well. While there is work underway to handle large repositories through the commit graph work, Git's internal design has remained surprisingly constant throughout its history, which means that storing large files into Git comes with a significant and, ultimately, prohibitive performance cost. Thankfully, other projects are helping Git address this challenge. This article compares how Git LFS and git-annex address this problem and should help readers pick the right solution for their needs.

Games Leftovers

  • Epic Store influences developers to pull Steam releases

    Some game developers are pulling their upcoming releases from the Steam page entirely, or choosing to make their titles a timed exclusive with the Epic Games Store.

  • DiRT 4 Coming to macOS and Linux in 2019

    Feral Interactive today announced that DiRT 4, the acclaimed off-road and rally racing game, will be released on macOS and Linux in 2019.

  • HEARTBEAT, a monster-filled RPG looks really sweet and it's getting a Linux version

    While it may not arrive for Linux at release, the developer of the sweet looking RPG HEARTBEAT has confirmed their intention to do a Linux build.

    Speaking on both itch.io and Steam, they seem rather positive about putting out a Linux version of their rather interesting adventure.

  • Jon Shafer's At the Gates to finally released next month, with Linux support

    After nearly seven years of development, the strategy game Jon Shafer's At the Gates is going to release next month with Linux support. For those who don't recognise the name, Shafer is the designer behind Civilization V.

    A game I completely lost track of, after previously highlighting it back in 2013. The developer announced on Twitter today, that the release is finally happening on January 23rd, 2019. After sending a quick message, the developer confirmed to us Linux will see support at release.

  • Rocket League updated with progression tweaks and a second Rocket Pass

    Rocket League, the insanely addictive rocket-powered sports game from Psyonix, Inc. has a few important tweaks released along with the second Rocket Pass.

    Firstly, let's quickly go over the progression changes. They're not overly dramatic, but there's some nice differences. From now, every time you touch the ball you will get two points (limited to one per second), the win bonus was doubled from 50 to 100, the Weekly Win Bonus was expanded from two to three games along with a max per week going up from 14 to 21 wins. On top of that, placement matches now count towards your Bronze Season Reward Level which is a nice tweak.

    Additionally, they've finally added some leaderboards for the new Ranked modes and there's also plenty of bug fixes that have come in this month.

  • The Odd Realm to enter Early Access on Steam with Linux support in January

    The Odd Realm, the simulation game where you will lead a group of settlers to a new home is coming to Steam next month. Get your calendar out, mark down January 11th, 2019 for when it will be up and ready for purchase on Steam.

    We recently highlighted this one, so it might sound familiar. However, we didn't know when it would be coming to Steam.

  • The developer of the retro FPS 'DUSK' has confirmed a Linux build is on the way

    While we knew DUSK would be getting a Linux version, it's always good to see confirmation that's up to date and positive.

    When asked this month on Steam, if it was coming to Linux the developer said "Yep! Linux / Mac builds are on the way! STAY TUNED" which is a rather clear-cut reply about it.

  • Battle Royale Tycoon has you designing and building arenas to watch the AI fight

    Now available with Linux support in Early Access, Battle Royale Tycoon flips the hype train upside down and has you building the arena rather than fighting in it.

    I must admit, I'm surprised. I was genuinely expecting this to see a wave of negative reviews. So far though, it seems players actually like it. I'm happy to see that, because it's actually quite an interesting idea for a building/tycoon style game. It's styled more like a theme park building game, with you setting up various battle arenas.

Red Hat Openwashing Leadership, Promoting VirtIO-FS and Explaining HID

tuxmachines.org - Tor, 12/11/2018 - 19:30
  • 5 things you won't learn from The Open Organization Leaders Manual

    Today the open organization community—a global group of writers, consultants, theorists, managers, and other organizational leaders dedicated to helping others understand how open principles can transform organizational culture and design—unveiled the second edition of The Open Organization Leaders Manual. Billed as "a handbook for building innovative and engaged teams," the book is available now as a Creative Commons-licensed eBook and a paperback.

  • Companies behind on digital transformation get ahead with open leaders

    One source of that disruption is digitization. Digitization is reshaping the way we lead, manage, and work. Even in the scope of the last decade, we've seen rapid adjustments to how we live, connect, and receive services. While we've been discussing ad nauseum how (or whether) we should be redefining organizational cultures and business models, the clock has been ticking, and the pace of digitization has not been slowing. In his book The Digital Matrix: New Rules for Business Transformation Through Technology, author Venkat Venkatraman argues that, by 2025, differences between digital and non-digital functions, processes, and business models will no longer exist.

  • VirtIO-FS: A Proposed Better Approach For Sharing Folders/Files With Guest VMs

    Red Hat developers have proposed a new VirtIO-FS component to provide better support for shared folders/files between the host and guest virtual machines. 

    VirtIO-FS was developed out of the need to share folders/files with guest VMs in a fast, consistent, and secure manner. They designed VirtIO-FS for Kata containers but coud be used with other VMs too. The closest existing project to fulfilling their needs was Virtio-9p, but there were performance issues and other factors leading them to designing this new solution.

  • Peter Hutterer: Understanding HID report descriptors

    This time we're digging into HID - Human Interface Devices and more specifically the protocol your mouse, touchpad, joystick, keyboard, etc. use to talk to your computer.

    Remember the good old days where you had to install a custom driver for every input device? Remember when PS/2 (the protocol) had to be extended to accommodate for mouse wheels, and then again for five button mice. And you had to select the right protocol to make it work. Yeah, me neither, I tend to suppress those memories because the world is awful enough as it is.

    As users we generally like devices to work out of the box. Hardware manufacturers generally like to add bits and bobs because otherwise who would buy that new device when last year's device looks identical. This difference in needs can only be solved by one superhero: Committee-man, with the superpower to survive endless meetings and get RFCs approved.

    Many many moons ago, when USB itself was in its infancy, Committee man and his sidekick Caffeine boy got the USB consortium agree on a standard for input devices that is so self-descriptive that operating systems (Win95!) can write one driver that can handle this year's device, and next year's, and so on. No need to install extra drivers, your device will just work out of the box. And so HID was born. This may only an approximate summary of history.

    Originally HID was designed to work over USB. But just like Shrek the technology world is obsessed with layers so these days HID works over different transport layers. HID over USB is what your mouse uses, HID over i2c may be what your touchpad uses. HID works over Bluetooth and it's celebrity-diet version BLE. Somewhere, someone out there is very slowly moving a mouse pointer by sending HID over carrier pigeons just to prove a point. Because there's always that one guy.

    HID is incredibly simple in that the static description of the device can just be bytes burnt into the ROM like the Australian sun into unprepared English backpackers. And the event frames are often an identical series of bytes where every bit is filled in by the firmware according to the axis/buttons/etc.
