  • The State of Virtual Reality on Linux

    …Until after some life changes, an unexpected influx of money, and curious about all the news about Half-Life next installment (Alyx) and Valve’s own VR system, the Valve Index, and the claims that it is supported on Linux, I took the plunge and bought it. I got it on my house on April 30, 2020, an exact year after its debut. What happened to me next was extraordinary. I met new worlds, I felt new things, I traveled to many places in the hardest months of the Lock-downs. It is not easy to describe, since it is so linked to the senses, so real and at the same time so abstract. In this article, I’ll try to laboriously describe what I felt — without ever leaving Linux — and give numerous examples. For that, though, I have to start with boring stuff. Stay with me and you won’t regret. So. This article will try to convey how Virtual Reality on Linux became viable, what are its challenges and limitations, which applications and games run on it, what are the terms and technologies associated to it and what to expect from the future. And also give a light whether it’s worth investing on this technology today, instead of waiting for it to mature as most people must think.

  • Valve Is Planning Something Special For Linux Gaming In 2021

    Before we get to that carrot Valve is dangling in front of us for 2021, let’s begin with a sobering observation. Despite two straight years of incredible advancements in Linux gaming — specifically Proton, the compatibility layer that lets us easily run thousands of Windows games on Linux — there has been a negligible increase in Linux gaming adoption. As marketing-centric scribe James Mawson so poignantly states, it’s a “growth so feeble, it’s difficult to separate from statistical noise; Linux isn’t even a serious threat to the Mac in this space.” Wow. Sobering indeed. Clearly We Have Work To Do Proton 5 now ships with the Steam for Linux client, and it introduces improved performance, support for DX12 and much more. As Valve’s informative 2020 recap points out, an increase in developers testing their games against Proton (without needing to invest huge time and resources into developing native ports) resulted in some big AAA titles like Death Stranding, Cyberpunk 2077 and others being playable on Linux at or shortly after their native Windows releases. That’s wonderful for gamers already immersed in the Linux gaming ecosystem, but let’s be honest with ourselves and admit that there are still many reasons to dual-boot Windows. Maybe it’s the lure of popular games that rely on anti-cheat software or invasive DRM. Maybe it’s the subpar support for brand new hardware like the Radeon RX 6000 GPUs.

  • Axiom Verge gets a first ever free update six years later with the Randomizer Mode

    While work continues on the sequel, Axiom Verge has a first ever free content update following the release back in 2015 with a new Randomizer Mode. Never played Axiom Verge? You're missing out. A true love-letter to the classic metroidvanias! This brand new update is currently in Beta, requiring you on Steam to opt into it in the usual way. Right click the game, go to Properties and hit Betas on the left panel and find it there. As the name of the update might suggest, it makes things a bit more random but "in a very sophisticated way". This mode is smart enough so you won't get stuck because of needing a certain item to progress onwards. How did it come about so long after release? Thanks to the speedrunning community, along with a developer of a mod that gave players an unofficial version of this but it needed a copy of the game. They teamed up to add it into the base game with the modder refusing any compensation for it. How nice for all of us!

  • Stockholm to host the 2021 CS:GO Major, with the biggest ever prize pool

    Valve along with PGL have announced the return of Counter-Strike: Global Offensive's next Major Championship that will take place this year in Sweden. Not only has competitive esport CS:GO returned, it's coming back with a bang too. This will be the biggest single prize pool in CS:GO history with twenty four teams competing for 2 million dollars USD. Not only that, this will also be the first event that is broadcast live in 4K resolution. The main event will be during November 4-7, so they're leaving enough time to hopefully see COVID-19 get a little more under control as this will be an in-person event with a live audience.

Mozilla: Rust, Socorro, and 'Healthier' Internet (Openwashing)

  • Another Rust-y OS: Theseus joins Redox in pursuit of safer, more resilient systems

    Rust, a modern system programming language focused on performance, safety and concurrency, seems an ideal choice for creating a new operating system, and several such projects already exist. Now there is a new one, Theseus, described by creator Kevin Boos as "an Experiment in Operating System Structure and State Management." The key thinking behind Theseus is to avoid what Boos and three other contributors from Rice and Yale universities call "state spill".

  • Socorro Engineering: Half in Review 2020 h2 and 2020 retrospective

    2020h1 was rough. 2020h2 was also rough: more layoffs, 2 re-orgs, Covid-19. I (and Socorro and Tecken) got re-orged into the Data Org. Data Org manages the Telemetry ingestion pipeline as well as all the things related to it. There's a lot of overlap between Socorro and Telemetry and being in the Data Org might help reduce that overlap and ease maintenance. [...] 2020 sucked. At the end, I was feeling completely demoralized and deflated.

  • Reimagine Open: Building a Healthier Internet

    Does the “openness” that made the [Internet] so successful also inevitably lead to harms online? Is an open [Internet] inherently a haven for illegal speech, for eroding privacy and security, or for inequitable access? Is “open” still a useful concept as we chart a future path for the [Internet]?

    A new paper from Mozilla seeks to answer these questions. Reimagine Open: Building Better Internet Experiences explores the evolution of the open [Internet] and the challenges it faces today. The report catalogs findings from a year-long project of outreach led by Mozilla’s Chairwoman and CEO, Mitchell Baker. Its conclusion: We need not break faith with the values embedded in the open [Internet]. But we do need to return to the original conceptions of openness, now eroded online. And we do need to reimagine the open [Internet], to address today’s need for accountability and online health.

Kernel: Linux 5.11, TuxMake, Linux 5.12, and NVIDIA "Nouveau" Driver

  • 5.11 Merge window, part 2

    Linus Torvalds released the 5.11-rc1 prepatch and closed the 5.11 merge window on December 27. By that time, 12,498 non-merge changesets had been pulled into the mainline; nearly 2,500 of those wandered in after the first merge-window summary was written. Activity slowed down in the second week, as expected, but there were still a number of interesting features that found their way into the mainline.

  • Portable and reproducible kernel builds with TuxMake

    TuxMake is an open-source project from Linaro that began in May 2020 and is designed to make building Linux kernels easier. It provides a command-line interface and a Python library, along with a full set of curated portable build environments distributed as container images. With TuxMake, a developer can build any supported combination of target architecture, toolchain, kernel configuration, and make targets. Building a Linux kernel is not difficult. Follow the documentation, install the dependencies, and run a couple of make commands. However, if a developer wants to build for multiple architectures, with multiple toolchains, things get complicated quickly. Most developers and maintainers have a set of custom scripts that they have written and maintained to perform their required set of builds. TuxMake provides a common layer of abstraction to reduce the need for every developer to write their own build scripts. TuxMake publishes containers for various toolchain/architecture combinations. These containers eliminate the need for individual developers to source and install multiple toolchains and toolchain versions on their systems. It also makes builds reproducible and portable because now the environment in which a kernel is built is versioned and shareable across the internet and on mailing lists. TuxMake has two goals. First, remove the friction that may cause developers, especially new developers, to skip build testing for uncommon toolchain/architecture combinations. Second, to make it easier for builds and build problems to be described and reproduced.

  • Linux 5.12 To Allow Disabling Intel Graphics Security Mitigations - Phoronix

    The Linux 5.12 kernel will allow optional, run-time disabling of Intel graphics driver security mitigations, which so far is just in regards to last year's iGPU Leak vulnerability. This i915.mitigations= module parameter control is being added as part of finally fixing the Haswell GT1 graphics support that was fallout from this mitigaion. The drm-intel-gt-next pull request to DRM-Next for Linux 5.12 was sent in. Most notable is that fixing of the Haswell GT1 support that came from the clear residual security mitigations. Since that iGPU Leak mitigation for Gen7/Gen7.5 graphics was merged last year, Haswell GT1 graphics have resulted in hangs at boot. That's finally fixed up. Besides being in Linux 5.12, it should also get back-ported to recent stable kernel series as well.

  • Open-Source "Nouveau" Driver Now Supports NVIDIA Ampere - But Without 3D Acceleration - Phoronix

    Patches were sent out today that provide the open-source Linux kernel "Nouveau" driver with support for NVIDIA GeForce RTX 30 series "Ampere" graphics cards. But at the moment there is no 3D acceleration and the developers are blocked still by signed firmware requirements, so it's basically just a matter of having kernel mode-setting display support. Red Hat's Ben Skeggs sent out the pull request today that provides kernel mode-setting support for the RTX 30 "Ampere" graphics cards with the long-standing open-source NVIDIA "Nouveau" driver

Daniel Stenberg: Food on the table while giving away code

I founded the curl project early 1998 but had already then been working on the code since November 1996. The source code was always open, free and available to the world. The term “open source” actually wasn’t even coined until early 1998, just weeks before curl was born. In the beginning of course, the first few years or so, this project wasn’t seen or discovered by many and just grew slowly and silently in a dusty corner of the Internet. Already when I shipped the first versions I wanted the code to be open and freely available. For years I had seen the cool free software put out the in the world by others and I wanted to my work to help build this communal treasure trove.
