Quick Roundup

Games: Overland, Lutris, Dead Cells and Fossilize

  • The impressive squad-based survival strategy game Overland to release this autumn
    Overland from Finji is a beautiful looking and impressive squad-based strategy game and they've now announced a release window.
  • The open source game manager Lutris had another sweet update recently
    What's that, too many launchers or no easy way to manage GOG games on Linux? Lutris might solve this problem for you. Giving you the ability to install and manage games from Steam, GOG, Humble Store, Emulators and more it's a pretty handy application to keep around. This latest release is mostly improving on existing features like downloading the default Wine version when not already available, preventing duplicated entries when importing games from a 3rd party, one search bar to rule them all, improved log handling performance, using your discrete GPU by default on compatible systems and more.
  • Dead Cells - Rise of the Giant free DLC to release this week, over 1 million copies sold
    Ready for just one more run? The Dead Cells - Rise of the Giant free DLC is releasing this week (March 28th) as Motion Twin celebrate good sales. The developer spoke at GDC and they went on to mention that Dead Cells has now officially sold over 1 million copies! Around 60% of that was on PC too, so the indie market for good games is still alive and well by the looks of it.
  • Fossilize Is Valve's Latest Open-Source Vulkan Project
    Valve Software has been backing work on Fossilize as an open-source project providing a serialization format for persistent Vulkan object types. Valve has been backing Hans-Kristian Arntzen to work on this Vulkan project while it has also seen commits by their in-house Vulkan guru Dan Ginsburg. The Fossilize library and Vulkan layer is intended so these persistent Vulkan persistent object types can be backed by the pipeline cache, a Vulkan layer to capture the cache, and the ability to replay the cache on different devices without having to run the application itself.

  • Canonical Reportedly Not Planning To Enable Wayland-By-Default For Ubuntu 20.04 LTS
    Since the short-lived Ubuntu 17.10 GNOME + Wayland experience, the Ubuntu desktop has still been using the trusted X.Org Server session by default. While Ubuntu 19.04 will soon be shipping and the Ubuntu 19.10 development cycle then getting underway, don't look for any Wayland-by-default change to be around the corner. Twice in the past week I've received communication from two indicating that Canonical reportedly isn't planning on enabling Wayland-by-default for Ubuntu 20.04 LTS. If Canonical were planning to go ahead with Wayland used by default, they would need to make the change for Ubuntu 19.10 as is customary for them to make large changes in the LTS-release-1 version in order to facilitate more widespread testing ahead of the Long Term Support cycle. But Canonical engineers feel that the Wayland support isn't mature enough to enable in the next year for Ubuntu 20.04 LTS.
  • Vulkan Working To Expose Video Encode/Decode, Machine Learning
    During this week's Game Developers Conference was the usual Khronos Dev Day where Vulkan, WebGL, glTF, and OpenXR took center stage. During the Vulkan State of the Union some details on their future endeavors were covered. Among some of the larger efforts that are "in flight" are improving the portability of Vulkan to closed platforms without native drivers (MoltenVK, etc), continuing to work on ray-tracing (complementing the existing VK_NV_ray_tracing), exposing video encode/decode through Vulkan, exposing machine learning capabilities, and the separate effort on safety critical Vulkan.

OSS: Blockchain, DeepBrain, Redox OS, OpenBuilds, Red Hat Summit and FOSSASIA

  • It's About Time DApps Unlocked the Mass-Market Momentum for Blockchain
    There’s more to Blockchain technology than Bitcoin and other cryptocurrencies. At its fundamental level, Blockchain technology engenders trusts in inherently trustless environments. Protocol blockchains such as Bitcoin, Ethereum, EOS, GoChain, Steem and xDai have provided a launchpad for developers to work on DApps. DApps are typically open source applications not owned by anyone, immune from downtimes; and that cannot be shut down by a government or its agencies. The rapid proliferation of Decentralized Applications (DApps) powered a bull run in cryptocurrencies in 2017. Right now, there are more than 2000 DApps designed to solve specific market problems across industries such as health, data storage, finance, gaming, and governance.
  • DeepBrain Chain outlines release of DBC 0.3.6.0 beta in progress report
    DeepBrain Chain detailed the release of DBC 0.3.6.0 beta of its AI Training Net, which allows users to rent computing power to train artificial intelligence algorithms. DeepBrain Chain claimed numerous feature inclusions and and improvements, many pertaining to the scheduling and activation of tasks. In DBC 0.3.6.0, if an AI training task has been stopped a specified period of time, its storage will be deleted automatically. However, the task can be restarted at any time before deletion. If a node has been restarted, reactivation of any previous training tasks will require manual user authorization. [...] A decision was made recently by the community concerning the open source licensing of DeepBrain Chain’s code. Over 55 percent of the members polled voted to not make the code fully open source by the end of March.
  • Redox OS 0.5.0
    It has been one year and four days since the last release of Redox OS! In this time, we have been hard at work improving the Redox ecosystem. Much of this work was related to relibc, a new C library written in Rust and maintained by the Redox OS project, and adding new packages to the cookbook. We are proud to report that we have now far exceeded the capabilities of newlib, which we were using as our system C library before. We have added many important libraries and programs, which you can see listed below.
  • Redox OS 0.5 Released With New C Library Written In Rust
    It's been just over one year since the previous release of Redox OS while today this Rust-written operating system has finally been succeeded by Redox OS 0.5.  It's taken a while since the previous release of Redox OS as they have been focusing their attention on Relibc, a C library implementation written within the Rust programming language. Relibc is now used as the operating system's default C library.
  • Get Moving with New Software from OpenBuilds
    If you’re reading Hackaday, you’ve probably heard of OpenBuilds. Even if the name doesn’t sound familiar, you’ve absolutely seen something on these pages that was built with their components. Not only is OpenBuilds a fantastic place to get steppers, linear rails, lead screws, pulleys, wheels, and whatever else you need to make your project go, they’re also home to an active forum of people who are passionate about developing open source machines. As if that wasn’t enough reason to head over to the OpenBuilds website, [Peter Van Der Walt] recently wrote in to tell us about some new free and open source software he and the team have been working on that’s designed to make it easier than ever to get your creations cutting, lasing, milling, and whatever else you could possibly imagine. If you’ve got a machine that moves, they’ve got some tools you’ll probably want to check out.
  • Dive into developer-focused sessions at Red Hat Summit
    Red Hat Summit is just around the corner, and it’s shaping up to be best Red Hat developer event ever. This year, attendees will get to choose from more than 300 sessions, not to mention booth presentations, parties, labs, and training. To help you cut through the clutter, we’ve created a list of developer specific activities and sessions that will help you shape your Red Hat Summit experience. Most of these sessions are part of the Cloud-Native App Dev track, with a few other sessions that we think will appeal to you as a developer. For more information on these sessions, visit the Red Hat Summit session listing page and sort by “cloud-native app dev” track.
  • 10th year of FOSSASIA
    This FOSSASIA was special as it marked its 10th year! It was quite impressive to witness a FOSS conference to continue growing this long with growing community. The four day conference schedule was packed with various interesting talks, workshops, hackathon and other engaging activities.

Reducing sysadmin toil with Kubernetes controllers

Kubernetes is a platform for reducing toil cunningly disguised as a platform for running containers. The element that allows for both running containers and reducing toil is the Kubernetes concept of a Controller. [...] The canonical example of this in action is in how we manage Pods in Kubernetes. A Pod is effectively a running copy of an application that a specific worker node is asked to run. If that application crashes, the kubelet running on that node will start it again. However, if that node crashes, the Pod is not recovered, as the control loop (via the kubelet process) responsible for the resource no longer exists. To make applications more resilient, Kubernetes has the ReplicaSet controller. The ReplicaSet controller is bundled inside the Kubernetes controller-manager, which runs on the Kubernetes master node and contains the controllers for these more advanced resources. The ReplicaSet controller is responsible for ensuring that a set number of copies of your application is always running. To do this, the ReplicaSet controller requests that a given number of Pods is created. It then routinely checks that the correct number of Pods is still running and will request more Pods or destroy existing Pods to do so. By requesting a ReplicaSet from Kubernetes, you get a self-healing deployment of your application. You can further add lifecycle management to your workload by requesting a Deployment, which is a controller that manages ReplicaSets and provides rolling upgrades by managing multiple versions of your application's ReplicaSets.

  • Making the Most of your Memory with mmap

    Sometimes it seems that we have nearly infinite memory resources, especially compared to the tiny 48K RAM of yesteryear’s 8-bit computers. But today’s complex applications can soak up megabytes before you know it. While it would be great if developers planned their memory management for all applications, thinking through a memory management strategy is crucial for applications with especially RAM intensive features like image/video processing, massive databases, and machine learning.

    How do you plan a memory management strategy? It’s very dependent on your application and its requirements, but a good start is to work with your operating system instead of against it. That’s where memory mapping comes in. mmap can make your application’s performance better while also improving its memory profile by letting you leverage the same virtual memory paging machinery that the OS itself relies on. Smart use of the memory mapping API (Qt, UNIX, Windows) allows you to transparently handle massive data sets, automatically paging them out of memory as needed – and it’s much better than you’re likely to manage with a roll-your-own memory management scheme.

    Here’s a real-life use case of how we used mmap to optimize RAM use in QiTissue, a medical image application. This application loads, merges, manipulates, and displays highly detailed microscope images that are up to gigabytes in size. It needs to be efficient or risks running out of memory even on desktops loaded with RAM.

DebConf20 Conference to Be Hosted in Haifa, Israel, for Debian GNU/Linux 11

Filed under
Debian

A port city built in tiers, Haifa is found in the northern area of Israel, extending from the Mediterranean sea till the north slope of the Carmel Mountain National Park. Haifa it's the third-largest city in Israel after Jerusalem and Tel Aviv, and it is close to the biblical city Nazareth where Jesus studied and prayed.

In 2020, the Debian Project will celebrate 12 years since the first DebConf Debian developer conference, so they decided to choose Israel instead of Lisbon, Portugal, for next year's DebConf20 event despite the extensive discussions between the DebConf team and committee due to Israel's political system.

KDE neon 5.15 review - Speed bumps ahead

Filed under
KDE
Reviews

KDE neon 5.15 is a decent distro. But it's not quite as pain-free as some of its predecessors, and I've hit a bunch of highly disappointing errors and bugs that simply shouldn't be there. The network and phone experience needs to be better, smoother. There ought to be no crashes. Regressions are bad.

Then, the upgrade process is robust and tight, the system is beautiful, and it purrs like a tiger - do tigers purr actually? You get the idea. Very sleek, very slick. Fast. You have a wealth of great software and a well-designed desktop environment that blends the bleeding-edge with pro-thought and good speed, and without being utterly beta. I'm quite happy overall, but I don't like the lack of consistency between the live media and the installed system. Some of this feels rushed. A good release, but ultimately not calm enough for everyday use. Well, I guess that's what LTS is for. 7/10. That would be all for today.

More GNOME Shell / Mutter Performance Optimizations & Latency Reductions Still Coming

Filed under
GNOME

Over the course of the GNOME 3.32 that is nearly complete as well as GNOME 3.30 there was a lot of measurable performance fixes and enhancements to improve the fluidity of the GNOME desktop as well as addressing various latency issues. While in some areas these performance improvements make a night and day difference, work isn't done on enhancing GNOME's performance.

One of the developers leading the charge on enhancing/fixing the performance of GNOME Shell and Mutter in particular has been Canonical's Daniel Van Vugt. While he's already made great strides in fixing issues himself, reviewing and collaborating on other patches, etc, the job isn't done. Van Vugt shared there's still some big ticket work pending.

Pop OS 18.10 Linux Gaming Report: System76 Nails It For Nvidia And AMD Users

Filed under
OS
Gaming

Pop!_OS is, in my opinion, a seriously underappreciated Ubuntu-based operating that distinguishes itself in a couple major areas -- in addition to its utter simplicity and slick installer. It was created primarily to be the accompanying OS for the variety of custom Linux desktops and laptops produced by System76, and they've added some features I prefer not to live without regardless of what hardware I'm using.

First, Pop!_OS is one of the only distros I've tried that elegantly handles Hybrid graphics (that's Intel CPU + Nvidia GPU as seen in laptops like the ThinkPad X1 Extreme) out of the box. Moreover, System76 ships two versions of Pop!_OS: one designed for Intel/AMD, and one designed for Nvidia GPUs. The Nvidia ISO installs the proprietary driver so that users don't need to add a repository by hand and install it later.

NVIDIA GeForce GTX 1660 Linux Benchmarks

Filed under
Graphics/Benchmarks

Last week NVIDIA announced the GeForce GTX 1660 as the newest RTX-less Turing GPU but costing only $219+ USD. The GTX 1660 is a further trimmed down version of the GeForce GTX 1660 Ti that launched several weeks prior. After picking up an ASUS GeForce GTX 1660 Phoenix Edition, here are Linux OpenGL/Vulkan gaming benchmarks compared to a wide assortment of AMD Radeon and NVIDIA GeForce graphics cards under Ubuntu.

The GeForce GTX 1660 features 1408 CUDA cores (compared to 1536 with the GTX 1660 Ti) while having a 1785MHz boost clock frequency and 1530MHz base clock frequency. The GeForce GTX 1660 opts for 6GB of GDDR5 unlike the 6GB GDDR6 used by the GTX 1660 Ti, which means only around 192GB/s of video memory bandwidth compared to 288GB/s with the Ti model. The other specifications are largely in common with the GeForce GTX 1660 Ti and the other Turing GPUs aside from lacking the RT/tensor cores.

Handling Complex Memory Situations

Filed under
Linux

Jérôme Glisse felt that the time had come for the Linux kernel to address seriously the issue of having many different types of memory installed on a single running system. There was main system memory and device-specific memory, and associated hierarchies regarding which memory to use at which time and under which circumstances. This complicated new situation, Jérôme said, was actually now the norm, and it should be treated as such.

The physical connections between the various CPUs and devices and RAM chips—that is, the bus topology—also was relevant, because it could influence the various speeds of each of those components.

Jérôme wanted to be clear that his proposal went beyond existing efforts to handle heterogeneous RAM. He wanted to take account of the wide range of hardware and its topological relationships to eek out the absolute highest performance from a given system.

From/on the Linux Foundation:

  • Sysdig Joins the Linux Foundation's New Foundation to Support Continuous Delivery Collaboration
  • Linux Foundation Launches Red Team Project

    The Linux Foundation has launched a new project aimed at incubating open source cybersecurity tools. The Red Team Project's main goal is to make open source software safer to use.

    The aim is to create cybersecurity tools for areas including cyber range automation, containerized pentesting utilities, binary risk quantification, and standards validation and advancement.

    [...]

    Current tooling from the project start with a Linux Exploit Mapper (LEM) that scans a Linux system for local exploits and maps them to known exploit code. When exploits are discovered using the mapper, they are curated, tested for efficacy and ease-of-use using a variant of the STRIDE scoring mechanism. An Ansible role called cyber-range-target is used to deliberately downgrade OS packages to a version vulnerable to a given CVE (Common Vulnerabilities and Exposure) for assessment purposes. The project also provides a Red Container. This offers containerized pentesting tooling, which can be launched from whole OSes or containerized environments like Kubernetes.

    Since the short-lived Ubuntu 17.10 GNOME + Wayland experience, the Ubuntu desktop has still been using the trusted X.Org Server session by default. While Ubuntu 19.04 will soon be shipping and the Ubuntu 19.10 development cycle then getting underway, don't look for any Wayland-by-default change to be around the corner. Twice in the past week I've received communication from two indicating that Canonical reportedly isn't planning on enabling Wayland-by-default for Ubuntu 20.04 LTS. If Canonical were planning to go ahead with Wayland used by default, they would need to make the change for Ubuntu 19.10 as is customary for them to make large changes in the LTS-release-1 version in order to facilitate more widespread testing ahead of the Long Term Support cycle. But Canonical engineers feel that the Wayland support isn't mature enough to enable in the next year for Ubuntu 20.04 LTS.
  • Vulkan Working To Expose Video Encode/Decode, Machine Learning
    During this week's Game Developers Conference was the usual Khronos Dev Day where Vulkan, WebGL, glTF, and OpenXR took center stage. During the Vulkan State of the Union some details on their future endeavors were covered. Among some of the larger efforts that are "in flight" are improving the portability of Vulkan to closed platforms without native drivers (MoltenVK, etc), continuing to work on ray-tracing (complementing the existing VK_NV_ray_tracing), exposing video encode/decode through Vulkan, exposing machine learning capabilities, and the separate effort on safety critical Vulkan.

OSS: Blockchain, DeepBrain, Redox OS, OpenBuilds, Red Hat Summit and FOSSASIA

  • It's About Time DApps Unlocked the Mass-Market Momentum for Blockchain
    There’s more to Blockchain technology than Bitcoin and other cryptocurrencies. At its fundamental level, Blockchain technology engenders trusts in inherently trustless environments. Protocol blockchains such as Bitcoin, Ethereum, EOS, GoChain, Steem and xDai have provided a launchpad for developers to work on DApps. DApps are typically open source applications not owned by anyone, immune from downtimes; and that cannot be shut down by a government or its agencies. The rapid proliferation of Decentralized Applications (DApps) powered a bull run in cryptocurrencies in 2017. Right now, there are more than 2000 DApps designed to solve specific market problems across industries such as health, data storage, finance, gaming, and governance.
  • DeepBrain Chain outlines release of DBC 0.3.6.0 beta in progress report
    DeepBrain Chain detailed the release of DBC 0.3.6.0 beta of its AI Training Net, which allows users to rent computing power to train artificial intelligence algorithms. DeepBrain Chain claimed numerous feature inclusions and and improvements, many pertaining to the scheduling and activation of tasks. In DBC 0.3.6.0, if an AI training task has been stopped a specified period of time, its storage will be deleted automatically. However, the task can be restarted at any time before deletion. If a node has been restarted, reactivation of any previous training tasks will require manual user authorization. [...] A decision was made recently by the community concerning the open source licensing of DeepBrain Chain’s code. Over 55 percent of the members polled voted to not make the code fully open source by the end of March.
  • Redox OS 0.5.0
    It has been one year and four days since the last release of Redox OS! In this time, we have been hard at work improving the Redox ecosystem. Much of this work was related to relibc, a new C library written in Rust and maintained by the Redox OS project, and adding new packages to the cookbook. We are proud to report that we have now far exceeded the capabilities of newlib, which we were using as our system C library before. We have added many important libraries and programs, which you can see listed below.
  • Redox OS 0.5 Released With New C Library Written In Rust
    It's been just over one year since the previous release of Redox OS while today this Rust-written operating system has finally been succeeded by Redox OS 0.5.  It's taken a while since the previous release of Redox OS as they have been focusing their attention on Relibc, a C library implementation written within the Rust programming language. Relibc is now used as the operating system's default C library.
  • Get Moving with New Software from OpenBuilds
    If you’re reading Hackaday, you’ve probably heard of OpenBuilds. Even if the name doesn’t sound familiar, you’ve absolutely seen something on these pages that was built with their components. Not only is OpenBuilds a fantastic place to get steppers, linear rails, lead screws, pulleys, wheels, and whatever else you need to make your project go, they’re also home to an active forum of people who are passionate about developing open source machines. As if that wasn’t enough reason to head over to the OpenBuilds website, [Peter Van Der Walt] recently wrote in to tell us about some new free and open source software he and the team have been working on that’s designed to make it easier than ever to get your creations cutting, lasing, milling, and whatever else you could possibly imagine. If you’ve got a machine that moves, they’ve got some tools you’ll probably want to check out.
  • Dive into developer-focused sessions at Red Hat Summit
    Red Hat Summit is just around the corner, and it’s shaping up to be best Red Hat developer event ever. This year, attendees will get to choose from more than 300 sessions, not to mention booth presentations, parties, labs, and training. To help you cut through the clutter, we’ve created a list of developer specific activities and sessions that will help you shape your Red Hat Summit experience. Most of these sessions are part of the Cloud-Native App Dev track, with a few other sessions that we think will appeal to you as a developer. For more information on these sessions, visit the Red Hat Summit session listing page and sort by “cloud-native app dev” track.
  • 10th year of FOSSASIA
    This FOSSASIA was special as it marked its 10th year! It was quite impressive to witness a FOSS conference to continue growing this long with growing community. The four day conference schedule was packed with various interesting talks, workshops, hackathon and other engaging activities.

Reducing sysadmin toil with Kubernetes controllers

Kubernetes is a platform for reducing toil cunningly disguised as a platform for running containers. The element that allows for both running containers and reducing toil is the Kubernetes concept of a Controller. [...] The canonical example of this in action is in how we manage Pods in Kubernetes. A Pod is effectively a running copy of an application that a specific worker node is asked to run. If that application crashes, the kubelet running on that node will start it again. However, if that node crashes, the Pod is not recovered, as the control loop (via the kubelet process) responsible for the resource no longer exists. To make applications more resilient, Kubernetes has the ReplicaSet controller. The ReplicaSet controller is bundled inside the Kubernetes controller-manager, which runs on the Kubernetes master node and contains the controllers for these more advanced resources. The ReplicaSet controller is responsible for ensuring that a set number of copies of your application is always running. To do this, the ReplicaSet controller requests that a given number of Pods is created. It then routinely checks that the correct number of Pods is still running and will request more Pods or destroy existing Pods to do so. By requesting a ReplicaSet from Kubernetes, you get a self-healing deployment of your application. You can further add lifecycle management to your workload by requesting a Deployment, which is a controller that manages ReplicaSets and provides rolling upgrades by managing multiple versions of your application's ReplicaSets.
