Random sampling from a file

Surreal adventure game 'ZED' about an artist suffering from dementia is releasing in June

2019-05-23 18:48:57

Tags: Adventure, Coming Soon, SteamZED, a game that will tell the story of an artist suffering from dementia from Eagre Games and Cyan Ventures now has a release date and it's quite soon. The Windows version is now scheduled in for June 4th, with the Linux (and Mac) version to be "later in June". Great to see it continue to be confirmed and although there is a delay, it's not going to be long it seems. Good thing too, as I'm damn excited for this one. “It’s exciting to release ZED as the first, in what we hope is, a series of artisan indie titles.'' said Rand Miller, CEO of Cyan. “Cyan Ventures was created to connect our amazingly supportive Myst fan base to inspiring artists like Chuck at Eagre Games. We hope that ZED, with its graphically mesmerizing narrative, will resonate with our fans and audiences worldwide.” Watch video on YouTube.com “I am thrilled to be working with Cyan Ventures” said Chuck Carter, founder of Eagre Games. “It is awesome to be working with a publisher as vested in the visual fidelity and compelling story as us. They believed in our vision and helped us move ZED across the finish line, from its Kickstarter inception to a deeply moving story of an unexamined life.” Everything about it looks and sounds like it's going to be an awesome experience. Possibly a confusing one with the theme, since your character will be desperately trying to reconnect fragmented memories. The way you do this, will be through the dreams of the artist's deteriorating mind. They say it "blends adventure, a rich narrative, stirring sentiment, and fanciful world exploration" which sounds pretty fancy. I'm a sucker for a good story, so I hope the writing holds up. I will let you know when we're provided with an update on the exact date of the Linux release. For now, you can wishlist/follow it on Steam ready. From the info I was given, it will also be releasing on GOG.

Compact, Linux-driven edge server supports Nvidia T4 GPUs

2019-05-23 17:14:53

Atos’ suitcase-sized “BullSequana Edge” server runs Linux on a 6th Gen Xeon-D and supports AI edge processing via optional Nvidia T4 GPUs and FPGAs. Other specs include SATA, USB 3.0, GbE, and optional 10GbE, WiFi, 3G/4G, and LoRa. Establishing our scope of coverage on the low end is pretty easy — aside from the occasional new Arduino board, we tend to limit our coverage to embedded devices that run Linux. Yet, on the high end, where Linux runs on just about everything and edge computing is the latest craze, it’s increasingly difficult to draw lines between servers and high-end embedded gear. Size matters in this delineation, which is one reason why we’re covering Atos’ suitcase-sized, Linux-driven BullSequana Edge. read more

Server: RHEL 8, Docker, Containers and “Natty Narwhal” Still Alive

2019-05-23 15:43:36

What Is New Features In Red Hat Enterprise Linux 8 (RHEL 8)? Red Hat Enterprise Linux 8 (RHEL 8) was released on 2019-05-07. The first beta was announced on 14 November 2018. There are lot of opportunities in Devops to improve the IT infra to next generation so, Red Hat is more focus on this area. To give more space to developers, they were added a lot of tools that developer-friendly capabilities. IT infra has been moved from Physical servers to Virtual servers. Now, we are migrating from Virtual servers to Containers & Kubernetes. Distribution Release – Red Hat Enterprise Linux 8 The future of Docker containers Michael Crosby is one of the most influential developers working on Docker containers today, helping to lead development of containerd as well as serving as the Open Container Initiative (OCI) Technical Oversight Chair. At DockerCon 19, Crosby led a standing-room-only session, outlining the past, present and — more importantly — the future of Docker as a container technology. The early history of Docker is closely tied with Linux and, as it turns out, so too is Docker's future. Crosby reminded attendees that Docker started out using LXC as its base back in 2013, but it has moved beyond that over the past six years, first with the docker-led libcontainer effort and more recently with multi-stakeholder OCI effort at the Linux Foundation, which has developed an open specification for a container runtime. The specification includes the runc container runtime which is at the core of the open source containerd project that Crosby helps to lead. Containerd is a hosted project at the Cloud Native Computing Foundation (CNCF) and is one of only a handful of projects that, like Kubernetes, have "graduated", putting it in the top tier of the CNCF hierarchy in terms of project stability and maturity. Why Organizations Want A Kubernetes-based Container Service for Cloud The technology that powers IG Instagram run in Ubuntu Linux 11.04 (“Natty Narwhal”).

Programming: Kyma, Microsoft Entryism, Python, Go, and Fedora Summer Coding interns

2019-05-23 15:24:13

Kyma - extend and build on Kubernetes with ease According to this recently completed CNCF Survey, the adoption rate of Cloud Native technologies in production is growing rapidly. Kubernetes is at the heart of this technological revolution. Naturally, the growth of cloud native technologies has been accompanied by the growth of the ecosystem that surrounds it. Of course, the complexity of cloud native technologies have increased as well. Just google for the phrase “Kubernetes is hard”, and you’ll get plenty of articles that explain this complexity problem. The best thing about the CNCF community is that problems like this can be solved by smart people building new tools to enable Kubernetes users: Projects like Knative and its Build resource extension, for example, serve to reduce complexity across a range of scenarios. Even though increasing complexity might seem like the most important issue to tackle, it is not the only challenge you face when transitioning to Cloud Native.

Security: Curl, OpenSUSE, Equifax and Kubernetes

2019-05-23 15:11:50

Report from the curl bounty program We announced our glorious return to the “bug bounty club” (projects that run bug bounties) a month ago, and with the curl 7.65.0 release today on May 22nd of 2019 we also ship fixes to security vulnerabilities that were reported within this bug bounty program. OpenSUSE Adds Option To Installer For Toggling Performance-Hitting CPU Mitigations With the newly released openSUSE Leap 15.1 they have added an option to their installer for toggling the CPU mitigations around Spectre / Meltdown / Foreshadow / Zombieload to make it very convenient should you choose to retain maximum performance while foregoing the security measures. But it also allows disabling SMT/HT from the installer should you prefer maximum security. When installing openSUSE Leap 15.1 today, I was a bit surprised to see a "CPU mitigations" option that allows toggling the value similar to the mitigations= kernel command line option. Equifax just became the first company to have its outlook downgraded for a cyber attack Equifax just became the first company to have its outlook downgraded for a cyber attack Moody’s has just slashed its rating outlook on Equifax, the first time cybersecurity issues have been cited as the reason for a downgrade. Moody’s lowered Equifax’s outlook from stable to negative on Wednesday, as the credit monitoring company continues to suffer from the massive 2017 breach of consumer data. “We are treating this with more significance because it is the first time that cyber has been a named factor in an outlook change,” Joe Mielenhausen, a spokesperson for Moody’s, told CNBC. “This is the first time the fallout from a breach has moved the needle enough to contribute to the change.” Equifax could not immediately be reached for comment. Kubernetes security: 4 strategic tips As with all things security-related, “fingers crossed!” isn’t exactly a confident posture. Kubernetes offers a lot of powerful security-oriented features, and the community has shown a strong commitment toward the security of the project. But it’s always best to be proactive, especially if you or your teams are still relatively new to containers and orchestration. The fundamentals of security hygiene still largely apply, as we noted in our recent article, Kubernetes security: 5 mistakes to avoid. There’s also some new learning to be done to ensure you’re proactively managing the risks inherent in any new system, especially once it’s running in production. read more

Tags: Indie Game, Steam, Coming Soon, RacingFunselektor Labs, the developer of Absolute Drift has announced their latest game, art of rally. It might look stylish but it's not just a pretty face, as the developer is also focused on how the cars handle too. While we have a few racing games now like Grid Autosport, DiRT Rally/4 and some F1 games (plus a few that work with Steam Play), they're all quite serious business. art of rally looks to be taking a slightly less realistic focus while still providing a challenge, especially with the top-down view you get a better picture of what's up ahead. Watch video on YouTube.com The developer, Dune Casu from Funselektor Labs, has said they've overhauled the handling model over what was found in Absolute Drift. They've actually driven WRC cars from the 1990s, as well as attending the DirtFish rally school, so they can "gain a better understanding of rally cars and also the learning process that goes into learning how to rally". Features: Progress through the golden years of rally in Career Mode 30+ iconic rally cars from the 60s, 70s, 80s, Group B and Group S Completely overhauled handling from the car physics system of Absolute Drift 50 rally stages in Finland, Sardinia, Norway, Japan and Germany Repair performance damage between stages Daily and weekly challenges with leaderboards Original soundtrack by Tatreal Speaking to the developer on Twitter, they confirmed Linux support as long as Unity is in good shape (which it mostly is now). Will be keeping an eye on it as it looks like a lot of fun, might even be a Rally game that I'm not completely atrocious at. You can follow it on Steam.

I am delighted to share with folks the results of a project I have been helping out on for the last few months: implementation of "BigInt" in Firefox, which is finally shipping in Firefox 68 (beta). Mozilla GFX: WebRender newsletter #45 Hi there! I first published this newsletter episode on May 21st and hitting the publish button at the same time as Jessie who wrote an excellent announcement post about WebRender on the stable channel. We decided to unpublish the newsletter for a couple of days to avoid shadowing the other post. WebRender is a GPU based 2D rendering engine for web written in Rust, currently powering Mozilla’s research web browser servo and on its way to becoming Firefox‘s rendering engine. Mozilla Localization (L10N): L10n report: May edition Firefox 68 has officially entered Beta. The deadline to ship localization updates into this version is June 25. It’s important to remember that 68 is going to be an ESR version too: if your localization is incomplete on Jun 26, or contains errors, it won’t be possible to fix them later on for ESR. A lot of content has landed in Firefox 68 towards the end of the cycle. In particular, make sure to test the new stub installer in the coming weeks, and the redesigned about:welcome experience. Detailed instructions are available in this thread on dev-l10n. You should also check out this post on how to localize the new “Join Firefox” message. Partially related to Firefox Desktop: Facebook Container is quickly approaching version 2.0, adding several informative panels to the initial bare UI. Firefox 67 Released With Improved Performance Mozilla team has released Firefox 67 (May 21, 2019) today. In this article, we will show you what’s new in Firefox 67. Mozilla Firefox (known as Firefox) is a free and open-source web browser developed by the Mozilla Foundation. Firefox is available for Windows, OS X, Linux and mobile for Android. Emblematic Group and Mozilla Team Up to Showcase Next Generation of Storytelling on the Web Everything you share on the internet is a story. You read blog posts and watch videos that make you feel connected to people across the world. Virtual Reality has made these experiences even stronger, but it wasn’t available to most people as a storytelling tool, until now. This breakthrough in accessibility comes from VR pioneer and award winning journalist, Nonny de la Peña, who is founder & CEO of the immersive technology company Emblematic Group. Their newest initiative was to launch a browser based platform that allows anyone to tap into the immersive power of virtual reality, regardless of their technical background. That is exactly what they did with REACH. With support from like minded partners such as Mozilla and the John S. and James L. Knight Foundation, de la Peña launched the platform at the 2019 Sundance Film Festival. REACH completely simplifies authorship and distribution of virtual reality experiences using a simple drag and drop interface which anyone can access from any device, including a laptop, tablet, or smartphone. read more

The latest Beta, released today fixes another long-standing issue with gamepad Rumble support. Valve said they "Added support for rumble pass-through for virtual controllers. This fixes missing rumble support for any controllers opted into Steam Input, and rumble emulation support for the Steam controller.". We have some keys for 'Tank Maniacs' for those willing to test and give feedback Tank Maniacs, a crazy local multiplayer game that's all about blowing each other up is coming to Linux "soon" and we have keys for those willing to provide the developer with feedback. For those who haven't seen it before, check out the trailer below first to see if you would actually be interested: Create your AI, pick your robots and prepare for battle as Gladiabots has left Early Access Gladiabots makes me feel dumb, very dumb. It asks you to create various AI and assign them to robots, to face off against another team of robots in a battle arena. It's a strategy game of sorts, while also being a logic puzzle programming game at its heart as well. It offers up a single-player campaign, which realistically is just a (quite good) extended tutorial to get you ready to compete against other real people. This is where it really gets interesting, as it offers online play but it's of the asynchronous sort so you're not playing at the same time, meaning it doesn't actually need people online to play which makes it pretty sweet. Total War: THREE KINGDOMS is out and it comes with same-day Linux support Total War: THREE KINGDOMS, possibly one of the biggest Total War games yet is officially out.

Linux Foundation Statement on Huawei Entity List Ruling

2019-05-23 14:04:32

Thank you for your inquiry regarding concerns with a member subject to an Entity List Ruling.[1] While statements in the Executive Order prompting the listing used language granting a broader scope of authority, the Huawei Entity List ruling was specifically scoped to activities and transactions subject to the Export Administration Regulation (EAR). Open source encryption software source code was reclassified by the US Department of Commerce, Bureau of Industry and Security (BIS) effective September 20, 2016 as “publicly available” and no longer “subject to the EAR.”[2] Each open source project is still required to send a notice of the URL to BIS and NSA to satisfy the “publicly available” notice requirement in the EAR at 15 CFR § 742.15( b ). read more

Roguelike fantasy adventure 'Vambrace: Cold Soul' has a new feature trailer ahead of release next week

2019-05-23 13:42:35

Tags: Adventure, RPG, Roguelike, GOG, Steam, Coming SoonThe release of Vambrace: Cold Soul on May 28th is getting close now, it's quite an impressive looking game that I've been playing and they have a new feature trailer. I won't say too much on it myself before release but since I've had access for a while, I can say it works great on Linux. This trailer should give you a little more insight into what to expect from it before release: Watch video on YouTube.com As mentioned before when writing briefly about it, the artwork and feel of the combat certainly does give off a Darkest Dungeon vibe and that's because it's one of the games that inspired it. Features: Embark on an epic fantasy-adventure spanning 7 intriguing chapters. Complete sub-quests to unlock up to 26 new, thematic character skins. Assemble your party from 5 races and 10 unique classes of recruits. Craft items and armor from precious materials gathered on your trips. Make crucial decisions where one wrong turn can seal your party's fate. Prepare well or condemn your comrades to permanent death. Find codex pages to expand upon Ethera's history and mythical lore. At release on May 28th, the Linux version will be available on GOG and Steam.

IRKALLA, an incredibly stylish looking pixel-art tactical-action platformer is coming to Linux

2019-05-23 13:30:23

Tags: Indie Game, Teaser, Coming Soon, Action, PlatformerThe developers behind IRKALLA emailed in today and it grabbed my interest right away with the supremely stylish art behind it. The odd setting has my curiosity too, with mechs versus demons! According to the developer, it's a "platform-tactic game" so it has elements of an action platformer with character progression and some form of base defence building. IRKALLA has been in development for quite a few years now with their TIGForum post dating all the way back to 2013. We've been emailed today, as it seems development on it has been picked back up as they told me it's "finally coming together" and a Linux release is also confirmed of course. You can see their brand new teaser below, which is amusingly self-aware with the wording: Watch video on YouTube.com Features: Responsive platforming controls Endless enemy waves Base administration to build your defenses Character progression and weaponry customization Random Bosses Going by the information listed in their press info, they're also planning to have the game split across two different modes. There's a story campaign and a second endless challenge mode. Will be keeping a close eye on this one, could be something special.

We humans are very good at collaboration.

Our natural ability to make these types of adjustments allows us to collaborate on tasks big and small.

Crazy Compiler Optimizations

2019-05-23 11:30:00

by Zack Brown Kernel development is always strange. Andrea Parri recently posted a patch to change the order of memory reads during multithreaded operation, such that if one read depended upon the next, the second could not actually occur before the first. The problem with this was that the bug never could actually occur, and the fix made the kernel's behavior less intuitive for developers. Peter Zijlstra, in particular, voted nay to this patch, saying it was impossible to construct a physical system capable of triggering the bug in question. And although Andrea agreed with this, he still felt the bug was worth fixing, if only for its theoretical value. Andrea figured, a bug is a bug is a bug, and they should be fixed. But Peter objected to having the kernel do extra work to handle conditions that could never arise. He said, "what I do object to is a model that's weaker than any possible sane hardware." Will Deacon sided with Peter on this point, saying that the underlying hardware behaved a certain way, and the kernel's current behavior mirrored that way. He remarked, "the majority of developers are writing code with the underlying hardware in mind and so allowing behaviours in the memory model which are counter to how a real machine operates is likely to make things more confusing, rather than simplifying them!" Still, there were some developers who supported Andrea's patch. Alan Stern, in particular, felt that it made sense to fix bugs when they were found, but that it also made sense to include a comment in the code, explaining the default behavior and the rationale behind the fix, even while acknowledging the bug never could be triggered. But, Andrea wasn't interested in forcing his patch through the outstretched hands of objecting developers. He was happy enough to back down, having made his point. It was actually Paul McKenney, who had initially favored Andrea's patch and had considered sending it up to Linus Torvalds for inclusion in the kernel, who identified some of the deeper and more disturbing issues surrounding this whole debate. Apparently, it cuts to the core of the way kernel code is actually compiled into machine language. Paul said: We had some debates about this sort of thing at the C++ Standards Committee meeting last week. Pointer provenance and concurrent algorithms, though for once not affecting RCU! We might actually be on the road to a fix that preserves the relevant optimizations while still allowing most (if not all) existing concurrent C/C++ code to continue working correctly. (The current thought is that loads and stores involving inline assembly, C/C++ atomics, or volatile get their provenance stripped. There may need to be some other mechanisms for plain C-language loads and stores in some cases as well.) Go to Full Article

Total War: THREE KINGDOMS is out and it comes with same-day Linux support

2019-05-23 11:26:42

Tags: Strategy, Steam, Feral Interactive, Humble Store, BenchmarkTotal War: THREE KINGDOMS, possibly one of the biggest Total War games yet is officially out. Developed by Creative Assembly and published by SEGA, it was ported by Feral Interactive and they managed to get Linux support in right away. This is pretty amazing really, we've often had to wait for Linux ports of big releases (sometimes years) so this is an extremely welcome change. You can view the Linux & Mac release trailer below: Watch video on YouTube.com As expected from Feral Interactive, this is another Linux port using the Vulkan API. So you will need at a minimum for NVIDIA driver 418.56 and for AMD Mesa 19.0.1. Currently, they're not supporting Intel GPUs. As usual, they're supporting it on Ubuntu only. They said that other modern drivers and distributions should work fine but they're not officially supported. Something I've come to expect from Feral now is also here, their fancy launcher that allows you to pick your resolution, monitor, get support and so on is nicely styled for the release: It's a small thing but it's one of the reasons I appreciate Feral's work, as someone with multiple monitors, it really does help. It's the attention to the details! Benchmarks using the preset drop-down settings (no others were changed) with the built-in benchmark tool: Full benchmark details, click me Ultra Average: 42.7 Min: 8.8 Max: 170.7 High Average: 60.8 Min: 9.6 Max: 201.9 Medium Average: 91.2 Min: 22 Max: 210.9 Low Average: 166.5 Min: 10 Max: 284.7 The minimum FPS is always super low, as it seems the benchmark starts logging quite early before the scenes are fully loaded in. Frankly, I don't think the minimum FPS in this case should be looked at much. Full benchmark details, click me Ultra Average: 50.9 Min: 35.8 Max: 99.4 High Average: 70.5 Min: 32.2 Max: 177.4 Medium Average: 86 Min: 9.4 Max: 257.5 Low Average: 121.1 Min: 22.7 Max: 213.8 Of course benchmarks only tell you so much, they don't tell you if the game is actually stable through longer sessions or if it's any good. Both of those I aimed to find out and so far, it's getting a positive mark on both fronts. As someone who doesn't play Total War too often, I'm already appreciating a lot of smaller touches in Total War: THREE KINGDOMS. The seriously clean and clear interface for example, with the information overlay and quick-access to the main controls in the ESC main makes it incredibly easy to actually get going. I'm actually quite surprised, based on the benchmark I was fully expecting to have to tune my settings down a little. However, playing through on the Ultra preset (with one or two options set a little higher) has actually provided me with a very smooth experience. I don't expect any less from Feral though, they know their stuff when it comes to Linux ports and it clearly shows here. Pretty amazing to get such a high-profile release as soon as it's out, that's the kind of platform parity I really like to see. Feral Interactive have done well. The only downside, is that like other previous Total War ports the online multiplayer is not cross-platform. You can find Total War: THREE KINGDOMS on Humble Store, Feral Store and Steam. With thanks to Feral Interactive, my key came through today so this post will continue to be updated with more information.

The latest Steam Client Beta fixes Rumble support on Linux with Steam Input

2019-05-23 09:03:05

Tags: Steam, Valve, BetaSeems Valve are on a bit of a roll lately fixing up some long-standing issues in the Steam Client for Linux. They've been released quite a number of Beta client updates recently with Linux improvements, like the one last week which had a fix for a this two year old issue where you were unable to move games around if they had files bigger than 2GB. The latest Beta, released today fixes another long-standing issue with gamepad Rumble support. Valve said they "Added support for rumble pass-through for virtual controllers. This fixes missing rumble support for any controllers opted into Steam Input, and rumble emulation support for the Steam controller.". Speaking about it on Twitter, Valve developer Pierre-Loup Griffais said "Today's Steam client update adds support for rumble for emulated controllers; this required working around a kernel bug, which we're also fixing upstream: https://www.spinics.net/lists/linux-input/msg61613.html". Happy to see this getting attention, as someone who makes heavy use of their Steam Controller. Although testing a few games earlier with it turned on (DiRT 4, Bastion, Rocket League, BallisticNG) it still didn't give me any Rumble oddly. Possible I'm missing something as I've seen reports of it working sometimes for others.

Kernel: Wayland, NVIDIA and Linux Development (LWN)

2019-05-23 06:43:58

Problems Being Investigated Under Wayland Itches Program, Including Gaming Performance Last week we wrote about a "Wayland Itches" program being devised by prolific open-source contributor Hans de Goede of Red Hat. The goal of this program is to address itches/paper-cuts/problems in using GNOME Shell atop Wayland. He's received a fair amount of feedback so far and has some early indications to share. Hans de Goede wrote two blog posts today outlining the early feedback to his Wayland Itches project. Two items he is going to look into initially are middle-click on title/header bar to lower the Window not working for native applications and sudo/pfexec not working on Wayland. For the sudo/pfexec support, Hans is planning to optionally support the ability for GUI apps to connect when running as root. That was rejected upstream before but his plan is for this to be an optional feature for enabling the xauth file for allowing XWayland as root by GNOME-Shell/Mutter. NVIDIA 418.52.07 Linux Driver Wires In Two More Extensions NVIDIA today released the 418.52.07 Linux driver as an updated build intended for Vulkan developers with it introducing support for two more extensions. BPF: what's good, what's coming, and what's needed The 2019 Linux Storage, Filesystem, and Memory-Management Summit differed somewhat from its predecessors in that it contained a fourth track dedicated to the BPF virtual machine. LWN was unable to attend most of those sessions, but a couple of BPF-related talks were a part of the broader program. Among those was a plenary talk by Dave Miller, described as "a wholistic view" of why BPF is successful, its current state, and where things are going. Years ago, Miller began, Alexei Starovoitov showed up at a netfilter conference promoting his ideas for extending BPF. He described how it could be used to efficiently implement various types of switching fabric — any type, in fact. Miller said that he didn't understand the power of this idea until quite a bit later. The first half of the 5.2 merge window When he released the 5.1 kernel, Linus Torvalds noted that he had a family event happening in the middle of the 5.2 merge window and that he would be offline for a few days in the middle. He appears to be trying to make up for lost time before it happens: over 8,300 non-merge changesets have found their way into the mainline in the first four days. As always, there is a wide variety of work happening all over the kernel tree. DAX semantics In the filesystems track at the 2019 Linux Storage, Filesystem, and Memory-Management Summit, Ted Ts'o led a discussion about an inode flag to indicate DAX files, which is meant to be applied to files that should be directly accessed without going through the page cache. XFS has such a flag, but ext4 and other filesystems do not. The semantics of what the flag would mean are not clear to Ts'o (and probably others), so the intent of the discussion was to try to nail those down. Dan Williams said that the XFS DAX flag is silently ignored if the device is not DAX capable. Otherwise, the file must be accessed with DAX. Ts'o said there are lots of questions about what turning on or off a DAX flag might mean; does it matter whether there are already pages in the page cache, for example. He said that he did not have any strong preference but thought that all filesystems should stick with one interpretation. While Christoph Hellwig described things as "all broken", Ts'o was hoping that some agreement could be reached among the disparate ideas of what a DAX flag would mean. A few people think there should be no flag and that it should all be determined automatically, but most think the flag is useful. He suggested starting with something "super conservative", such as only being able to set the flag for zero-length files or only empty directories where the files in it would inherit the flag. Those constraints could be relaxed later if there was a need. A filesystem for virtualization A new filesystem aimed at sharing host filesystems with KVM guests, virtio-fs, was the topic of a session led by Miklos Szeredi at the 2019 Linux Storage, Filesystem, and Memory-Management Summit. The existing solution, which is based on the 9P filesystem from Plan 9, has some shortcomings, he said. Virtio-fs is a prototype that uses the Filesystem in Userspace (FUSE) interface. The existing 9P-based filesystem does not provide local filesystem semantics and is "pretty slow", Szeredi said. The FUSE-based virtio-fs (RFC patches) is performing "much better". One of the ideas behind the new filesystem is to share the page cache between the host and guests, so there would be no data duplication for multiple guests accessing the same files from the host filesystem. There are still some areas that need work, however. Metadata and the directory entry cache (dcache) cannot be shared, because data structures cannot be shared between the host and guests. There are two ways to handle that. Either there can be a round trip from the guest to the host for each operation to ensure the coherence of the metadata cache and dcache, or the guest can cache that information and somehow revalidate the cache on each operation without going to the host kernel. Common needs for Samba and NFS Amir Goldstein led a discussion on things that the two major network filesystems for Linux, Samba and NFS, could cooperate on at the end of day one of the 2019 Linux Storage, Filesystem, and Memory-Management Summit. In particular, are there needs that both filesystems have that the kernel is not currently providing? He had some ideas of areas that might be tackled, but was looking for feedback from the assembled filesystem developers. He has recently just started looking at the kernel NFS daemon (knfsd) as it is a lesser use case for the customers of his company's NAS device. Most use Samba (i.e. SMB). He would like to see both interoperate better with other operating systems, though. NFS topics Trond Myklebust and Bruce Fields led a session on some topics of interest in the NFS world at the 2019 Linux Storage, Filesystem, and Memory-Management Summit. Myklebust discussed the intersection of NFS and containers, as well adding TLS support to NFS. Fields also had some container changes to discuss, along with a grab bag of other areas that need attention. Myklebust began with TLS support for the RPC layer that underlies NFS. One of the main issues is how to do the upcall from the RPC layer to a user-space daemon that would handle the TLS handshake. There is kernel support for doing TLS once the handshake is complete; hardware acceleration of TLS was added in the last year based on code from Intel and Mellanox, he said. RPC will use that code, but there is still the question of handling the handshake. read more

OSI: Powering Potential and Open Source Hong Kong (OSHK)

2019-05-23 05:40:21

You're Invited: Celebrating Powering Potential. OSI Affiliate Member Powering Potential Inc. (PPI) is currently preparing for their annual fundraising event scheduled for Wednesday, June 5, 2019, from 6 to 8:30 p.m. at NoMad Studio, located at 29 W. 39th Street, 10th Floor, in New York City. This year PPI celebrates their 10 Year Partnership with the Segal Family Foundation. The close, long-time relationship has been a key factor in the amazing progress PPI has made in bringing their “Educating through Technology” programs to the rural students in Tanzania. Proceeds from this year’s event will go towards the Sazira Secondary School SPARC+ Lab Upgrade impacting 800+ students in rural Tanzania: an ambitious project needing $23,500. While this is significant, The Collegiate Churches of New York recently awarded Powering Potential a generous grant of $13,000 towards this goal. PPI has an incredible event planned for their guests. Back by popular demand, Tanzanian dancers performing traditional dance led by Justa Lujwangana, CEO and founder of Curious on Tanzania will provide entertainment for the evening. A buffet will also feature authentic Tanzanian dishes based on menus from Taste of Tanzania by Miriam Malaquais. The author has donated twenty of her books for sale at the event with proceeds going to PPI. Open Source Hong Kong Becomes an OSI Affiliate Member The Open Source Initiative (OSI), the founding organization of the open source software movement, is excited to announce the Affiliate Membership of the Open Source Hong Kong (OSHK). For ten years OSHK has worked across Asia to support open source communities, foster open source development, and increase the use of open source software, their recent OSI Membership highlights both organizations' desires to collaborate across communities. “OSHK mission is promoting Open Source Software projects in Hong Kong and foster its development by connecting to the global open source community. In joining OSI as an Affiliate Member, OSHK connects with OSI, and other open source organizations, to support the promotion of open source,' said Sammy Fung, President of OSHK. "Open Source Software is not just about viewing the source code, it also guarantees the right to use the software, and modify it for our own use. By working together, I believe both organizations will be able to extend our reach and missions." “We are excited to welcome OSHK as an OSI Affiliate Member,” said Molly de Blanc, OSI President. “The open source community truly is global, and their dedication to that idea is what inspires us as an organization. Our work for the future of open source is driven by that global community, and having the voices of OSHK in our affiliate membership helps us meet our goal in promoting and protecting open source and communities. We look forward to supporting their efforts and collaborating to help spread the message of open source even further.” read more

Games: GOG, Zork and Epic Games

2019-05-23 05:37:46

GOG are revamping GOG Galaxy, to help you manage multiple launchers and still no Linux support It's like a much fancier version of Steam's own ability to add games installed from other sources, as Galaxy 2.0 will also support cross-launcher friends lists and chat making it sound pretty darn handy. They do also state you can "Connect more platforms and add new features with open-source integrations.". Those hoping that is some kind of olive branch being extended for Linux will likely be disappointed though, going by their FAQ on the newer dedicated Galaxy site it sounds more like it's simply for adding other services into the client itself for those GOG haven't yet done. This would have been the perfect time to finally announce the ridiculously long-overdue Linux support for GOG Galaxy (especially with the Epic Store also not supporting Linux), sadly GOG are continuing to leave Linux out. In response to a user question on Twitter about Linux, the GOG team simply said "GOG GALAXY 2.0 will be available for Windows and Mac.". While an honest answer, it's also pretty blunt. No mention of it coming, just a whole lot of nothing. Zork And The Z-Machine: Bringing The Mainframe To 8-bit Home Computers Computer games have been around about as long as computers have. And though it may be hard to believe, Zork, a text-based adventure game, was the Fortnite of its time. But Zork is more than that. For portability and size reasons, Zork itself is written in Zork Implementation Language (ZIL), makes heavy use of the brand-new concept of object-oriented programming, and runs on a virtual machine. All this back in 1979. They used every trick in the book to pack as much of the Underground Empire into computers that had only 32 kB of RAM. But more even more than a technological tour de force, Zork is an unmissable milestone in the history of computer gaming. But it didn’t spring up out of nowhere. [...] While home computers were still scarce, the concept of selling software to regular consumers was also new. This was the time when the Atari 2600 had just gone on sale, starting the second generation game consoles that were expandable to play more that one game through the use of plug-in cartridges. It was a new market, with many questions among MIT, Stanford and other students regarding the open hacker culture versus the world of commercial software. Some, like Richard Stallman, not changing their stance on this much since their student days at MIT. As the Zork developers were graduating, they realized that with the success of Zork on their hands, they had this one chance to commercialize it, taking their lives and careers into an entirely different direction from their original goals. With little standing in their way, Infocom was founded on June 22nd, 1979. Gaming Platform War Update: Epic Games Store Suspends Accounts...For Buying Too Many Games As we've talked about before, it seems an era of gaming platform wars is upon us. While Valve's Steam platform mostly only had to contend with less-used storefronts like GOG and Origin, a recent front was opened up by the Epic Games Store, which has promised better cuts to publishers to get exclusive games and has attempted to wage a PR battle to make people mad at Steam. It's all quite involved, with opinions varying across the internet as to who the good and bad guys in this story are. read more

Space Station welcomes free-flying, Ubuntu-powered autonomous robots

2019-05-23 02:19:35

NASA has deployed three free-flying “Astrobee” robots on the ISS for house-keeping tasks. The bots run Ubuntu/ROS and Android 7.1 on Snapdragon-based Inforce modules and a Wandboard and feature 3x payload bays, 6x cameras, and a touchscreen. We haven’t heard a news from the IBM Watson connected CIMON social robot since it debuted with a truly strange video last December in which CIMON accused International Sopace Station astronaut Alexander Gerst of being “mean.” However, NASA has now deployed and tested three somewhat similar “Astrobee” robots on the ISS for assisting the astronauts rather than chatting them up. read more

Yet another Linux distribution shuts down, and the Open Source community should be worried

2019-05-23 01:00:35

More and more people are trying Linux-based operating systems these days, and with Windows 10 being so hated, that should not be a surprise. Sadly, while the Linux community should be thriving from Microsoft's missteps with Windows, it feels like the opposite is happening. The Linux Mint development team is experiencing turmoil, for instance, while Scientific Linux has shut down entirely. Unfortunately, things are getting even more dire, as yet another Linux distribution has shut down. This time, the operating system is the Arch-based Antergos. "Today, we are announcing the end of this project. As many of you probably noticed… [Continue Reading]

Problems Being Investigated Under Wayland Itches Program, Including Gaming Performance

2019-05-22 19:52:13

Last week we wrote about a "Wayland Itches" program being devised by prolific open-source contributor Hans de Goede of Red Hat. The goal of this program is to address itches/paper-cuts/problems in using GNOME Shell atop Wayland. He's received a fair amount of feedback so far and has some early indications to share...

Graphics: Red Hat's Wayland Agenda and AMD Begins Queueing Graphics Driver Changes For The Linux 5.3 Kernel

2019-05-22 19:46:27

Hans de Goede: Wayland itches summary 1. Middle click on title / header bar to lower the Window does not work for native apps. Multiple people have reported this issue to me. A similar issue was fixed for not being able to raise Windows. It should be easy to apply a similar fix for the lowering problem. There are bugs open for this here, here and here. 2. Running graphical apps via sudo or pxexec does not work. There are numerous examples of apps breaking because of this, such as lshw-gui and usbivew. At least for X11 apps this is not that hard to fix. But sofar this has deliberately not been fixed. The reasoning behind this is described in this bug. I agree with the reasoning behind this, but I think it is not pragmatic to immediately disallow all GUI apps to connect when run as root starting today. Hans de Goede: Better support for running games under Wayland (with GNOME3/mutter as compositor) First of all I do not want people to get their hopes up about $subject of this blogpost. Improving gaming support is a subjects which holds my personal interest and it is an issue I plan to spend time on trying to improve. But this will take a lot of time (think months for simple things, years for more complex things). AMD Begins Queueing Graphics Driver Changes For The Linux 5.3 Kernel Being past the Linux 5.2 kernel merge window, AMD's open-source Linux graphics driver developers have already begun queuing changes anticipated for Linux 5.3 via a work-in-progress tree. Given the short time that this 5.3 WIP tree has been around, there isn't too much exciting about the changes -- yet. But surely over the weeks ahead it will get interesting. Making things particularly interesting is that we are expecting initial Navi support to make it for Linux 5.3... In recent weeks AMD began pushing AMDGPU LLVM compiler back-end changes for GFX10/Navi and we expect the AMDGPU DRM kernel driver enablement to come for Linux 5.3. Linux 5.3 will already be arriving after the rumored release of the first Navi graphics cards so having to wait past 5.3 for mainline support would already be tragic. But given the recent LLVM activity, we expect AMD to push out the Navi kernel driver changes soon. For that likely massive patch-set to be reviewed in time, the Navi patches would need to make their debut within the next few weeks. read more

Fedora 30 Workstation review - Smarter, faster and buggier

2019-05-22 19:41:30

Fedora 30 is definitely one of the more interesting releases of this family in a long-time. It brings significant changes, including solid improvements in the desktop performance and responsiveness. Over the years, Fedora went from no proprietary stuff whatsoever to slowly acknowledging the modern needs of computing, so now it gives you MP3 codecs and you can install graphics drivers and such. Reasonable looks, plus good functionality across the board. However, there were tons of issues, too. Printing to Samba, video screenshot bug, installer cropped-image slides, package management complications, mouse cursor lag, oopses, average battery life, and inadequate usability out of the box. You need to change the defaults to have a desktop that can be used in a quick, efficient way without remembering a dozen nerdy keyboard shortcuts. All in all, I like the freshness. In general, it would seem the Linux desktop is seeing a cautious revival, and Fedora's definitely a happy player. But there are too many rough edges. Well, we got performance tweaks after so many years, and codecs, we might get window buttons and desktop icons one day back, too. Something like 6/10, and definitely worth exploring. I am happy enough to do two more tests. I will run an in-vivo upgrade on the F29 instance on this same box, and then also test the distro on an old Nvidia-powered laptop, which will showcase both the support for proprietary graphics (didn't work the last time) and performance improvements, if they scale for old hardware, too. That's all for now. read more

Red Hat and the rise of RHEL

2019-05-22 18:57:08

If the success of the open source company Red Hat can be ascribed to one thing, it's the Enterprise Linux operating system that it releases The company recently unveiled the general release of the latest version, RHEL 8, and it serves as a bellwether for how software development has changed over the years. Developers are now shouldering more operational responsibilities, which is largely due to the rise in the use of containers. This enables teams to use microservices to build applications. With RHEL 8, Red Hat has also placed container tools such as Buildah, Podman and Skopea directly into the operating system. read more

Red Hat, Fedora and SUSE/OpenStack

2019-05-22 18:55:56

Rook-Ceph storage Operator now on OperatorHub.io We are excited to announce the addition of the Rook-Ceph storage Operator to OperatorHub.io. Operators are design patterns that augment and implement common day one and day two activities with Kubernetes clusters, simplifying application deployments and empowering developers to focus on creation versus remediation. The Rook-Ceph Operator is an upstream effort that Red Hat is leading and is using as part of its work towards Red Hat OpenShift Container Storage 4. Developing and deploying cloud-native applications at scale can be complex and challenging. The new Rook-Ceph storage Operator is designed to automate the packaging, deployment, management, upgrading, and scaling of Ceph clusters that provide persistent storage to stateful applications as well as infrastructure services (logging, metrics, registry) in Kubernetes clusters. The release of Rook’s Ceph Operator augments Kubernetes scheduling with a complement of stateful storage services including block, filesystem and object storage. Red Hat Satellite 6.4.3 has been released Red Hat Satellite 6.4.3 is generally available. The main drivers for the 6.4.3 release are a Request for Feature Enhancement (RFE) for capsule syncing control as well as general stability fixes. The capsule syncing control feature enables the user to have control over when capsule syncs occur. Traditionally the capsule sync occurs automatically after a content view is updated, but some customers may want more granular control over when the synchronization occurs. Satellite 6.4.3 introduces a new setting in Administer —> Settings —> Content —> Sync Capsules after Content View promotion. Contributors are Empowered When They Know the Process There is a saying in the legal profession that you should never ask a question you don’t already know the answer to. Despite how this sounds, it is actually a rule most people follow in life. This is the source of that feeling you get when you’re too scared to raise your hand and ask a question. In Open Source we need to make sure that contributors feel like they already “know” the answers, so they will feel confident in making the request. As a university lecturer, I always encouraged my students to first think about what they thought the answer was and then ask the question. In some cases, I encouraged them to actually write down what they thought the answer was. In this way, they could judge both their skills and their ability to grow based on what the answer turned out to be. It created an additional feedback loop. Alisha and Shraddha: Positive feedback loops in Fedora This post is the second introduction to the Fedora Summer Coding interns Class of Summer 2019.

Usage in Asia surged dramatically in 2018, with 48% of respondents based in that continent, with Europe 2nd at 26% and North America 3rd with 20% of respondents. read more

GOG are revamping GOG Galaxy, to help you manage multiple launchers and still no Linux support

2019-05-22 18:52:37

Tags: GOG, AppsToday, GOG officially announced Galaxy 2.0 and their aim seems to be to pull everyone together under one roof. There are two things that matter to all of us gamers: the games we play and the friends we play them with. But as more titles come with dedicated launchers and clients, our games and gaming buddies become scattered in between them. With GOG GALAXY 2.0, you’ll be able to combine multiple libraries into one and connect with your friends across all gaming platforms! It's like a much fancier version of Steam's own ability to add games installed from other sources, as Galaxy 2.0 will also support cross-launcher friends lists and chat making it sound pretty darn handy. They do also state you can "Connect more platforms and add new features with open-source integrations.". Those hoping that is some kind of olive branch being extended for Linux will likely be disappointed though, going by their FAQ on the newer dedicated Galaxy site it sounds more like it's simply for adding other services into the client itself for those GOG haven't yet done. This would have been the perfect time to finally announce the ridiculously long-overdue Linux support for GOG Galaxy (especially with the Epic Store also not supporting Linux), sadly GOG are continuing to leave Linux out. In response to a user question on Twitter about Linux, the GOG team simply said "GOG GALAXY 2.0 will be available for Windows and Mac.". While an honest answer, it's also pretty blunt. No mention of it coming, just a whole lot of nothing. It's worth noting the wishlist entry "Release the GOG Galaxy client for linux" on GOG's own website with over 21K votes, has been listed as "in progress" for a long time now (at least as far back as 2015 going by the Wayback Machine). You would think by now we would have had some sort of sign. Considering even itch.io, a tiny little outfit has managed to support Linux really well with their open source client you would think after multiple years GOG would. I've reached out to GOG, to see if they would like a chat about it. I will update if/when they reply.

Programming: KubeCon, PHP, Python, GitLab, and Rust

2019-05-22 18:51:19

Team OpenCensus or OpenTracing? It'll be neither and both now: Hello, OpenTelemetry Something odd happened at KubeCon 2019. Rather than snipe at each other from the safety of Twitter, two very similar open-source projects opted to pool their ideas into one: OpenTelemetry. The project is geared towards solving the problem of working out just what the heck is happening in today's microservices or container-based apps. Logging without incurring a chunky overhead both in terms of generating useful telemetry and actually collating the output. Distributed tracing is a bit more than fancy logging, as one commentator put it. Think more a transaction log over all the containers, services and components used in an application. Two projects emerged to deal with the challenge – OpenCensus from Google and OpenTracing, co-created by Ben Sigelman of Lightstep. PHP 7.4 as Software Collection. Version 7.4.0-alpha1 will be soon released. It's now enter the stabilization phase for the developers, and the test phase for the users. RPM of this upcoming version of PHP 7.4, are available in remi repository for Fedora 29, 30 and Enterprise Linux 7, 8 (RHEL, CentOS, ...) in a fresh new Software Collection (php74) allowing its installation beside the system version. As I strongly believe in SCL potential to provide a simple way to allow installation of various versions simultaneously, and as I think it is useful to offer this feature to allow developers to test their applications, to allow sysadmin to prepare a migration or simply to use this version for some specific application, I decide to create this new SCL. HEIC / HEIF images support The HEIF image format (High Efficiency Image File Format) is now widely used, especially since iOS 11, so it make sense to be able to process these images.

Intel Iris Gallium3D Driver Gets On-Disk Shader Cache Support In helping to speed-up game load times when switching to the new Intel "Iris" Gallium3D OpenGL Linux driver and smooth out frame-rates for games sporadically loading shaders, Mesa 19.2-devel has added on-disk shader cache support for the driver. Intel's existing "i965" classic Mesa driver has long supported an on-disk shader cache along with the other Mesa OpenGL drivers while now the Gallium3D shader cache functionality has been extended for the new Iris driver. 10 Unknown Google Search Games for You Google Search by default has games hidden in it, which is a fact, not many Google users are aware of. Google has compiled some really authentic and entertaining games over a period of time, that can be played in Google.com page itself without having to visit any other Web page. Most of these games were made to appear as Google Doodle, in relation with certain anniversaries that have been a remarkable day in history. While some of these games are not available easily because Google Doodle keeps changing. However, a few of them continue to be played even today. All you need is to search the game by its name in Google and hit “search” and Voila! The games will appear right in front of your eyes and you can play them right then and there. Read on to know about the playable games still available, though hidden within the Google Search. Valve have released a new dedicated mobile Steam Chat application Now that Valve have upgraded the chat and friends system in the desktop Steam client, they've also rolled out a brand new dedication mobile application to do the same. This isn't the normal Steam mobile application, instead they've oddly decided to split them in two. Touching on that, they said the original Steam mobile application is going to get some upgrades "focused on account security" including better Steam Guard options, like QR codes and a one-touch login. Sci-fi first-person shooter 'Interstellar Marines' continues to live on, with a big update out now Interstellar Marines, a once promising sci-fi first-person shooter that slowly died is slowly making a comeback. Update 28 was released just recently, giving it an overhaul in a few places. Valve working on a stand-alone version of the popular Dota Auto Chess Dota Auto Chess, a very popular custom game mode for Dota 2 is being turned into a stand-alone game by Valve. The Dota 2 arcade is full of interesting games but nothing has really come close to Dota Auto Chess, looking at it right now it has over 125K people playing just this one game mode. It also has over 8 million people subscribed to it, to give you another idea of just how popular it is. Based on player-count, if it manages to keep it for the stand-alone version it would put it into the top-5 games on Steam. Blacksite returns alongside Sirocco for the latest Danger Zone update in Counter-Strike: Global Offensive Counter-Strike: Global Offensive's newer Battle Royale mode, Danger Zone, continues to be tweaked and the original map has made a return. This should help spice things up a bit, as Blacksite is quite a good map but I've also immensely enjoyed playing on the newer and more open Sirocco map. Thankfully, Valve have now enabled Danger Zone for both maps together as a "time-based map rotation" as you can see below: DXVK 1.2.1 really does improve Overwatch quite a lot on Linux with NVIDIA In the latest release of DXVK 1.2.1 that was released last week, it included a note about improved GPU utilization. They certainly weren’t kidding, with Overwatch now performing even better on Linux with Wine. When I previously wrote about it, I said I was in shock at how well you could play Overwatch on Linux thanks to Wine, DXVK and a little help from Lutris. I included a video in the previous article to show it off, which showed the framerate hardly going above 100FPS and often dipped down to around 60FPS. Checking back, previous versions of DXVK didn’t let my NVIDIA 980ti GPU utilization go above 80%.

At a recent talk on the UK's energy sector, the head of an electric utility company claimed that "the problem of decarbonising our electricity sector is fixed". Eyebrows were raised at this, but his point quickly became clear. The technologies needed to decarbonise the UK's electricity system now exist, he explained. Indeed, grid operators in the UK expect a zero carbon electricity system by 2025.

Blacksite returns alongside Sirocco for the latest Danger Zone update in Counter-Strike: Global Offensive

2019-05-22 14:05:11

Tags: Valve, Steam, Free Game, FPS, Battle RoyaleCounter-Strike: Global Offensive's newer Battle Royale mode, Danger Zone, continues to be tweaked and the original map has made a return. This should help spice things up a bit, as Blacksite is quite a good map but I've also immensely enjoyed playing on the newer and more open Sirocco map. Thankfully, Valve have now enabled Danger Zone for both maps together as a "time-based map rotation" as you can see below: Additionally, the Radar Jammer will now block the Drone Pilot perk with static interference when it's active, Drones will fly slower when carrying "paradrop crates" (the later-game airdrop with good weapons) and the Armour starting perk will now give you both the Body Armour and Helmet together as it should. Sadly, they've still not corrected the bug I reported where the Drone Pilot screen has a distorted area on it making it a nuisance to use, which seems to happen across both NVIDIA and AMD GPUs. Hopefully they will look into that soon. Apart from that, Danger Zone is a huge amount of fun so do give it a go. It will be interesting to see if they continue expanding it, the recent drop-in perk update with Sirocco was a big improvement. They do support their games for a long time and CS:GO continues to be one of the most popular games on Steam, so I doubt they're done yet. Additionally, CS:GO has updated "SDR libraries" to the latest version and they're now restricting the start of client-side demo recording on dedicated servers to "warmup and freezetime". They also did a few tweaks to the Vertigo and Sirocco maps. You can find Counter-Strike: Global Offensive free on Steam.

DXVK 1.2.1 really does improve Overwatch quite a lot on Linux with NVIDIA

2019-05-22 14:01:26

Tags: Wine, VideoIn the latest release of DXVK 1.2.1 that was released last week, it included a note about improved GPU utilization. They certainly weren’t kidding, with Overwatch now performing even better on Linux with Wine. When I previously wrote about it, I said I was in shock at how well you could play Overwatch on Linux thanks to Wine, DXVK and a little help from Lutris. I included a video in the previous article to show it off, which showed the framerate hardly going above 100FPS and often dipped down to around 60FPS. Checking back, previous versions of DXVK didn’t let my NVIDIA 980ti GPU utilization go above 80%. Testing it all out again now thanks to DXVK improvements, it’s quite a different story! GPU utilization is often around 98% and the frame-rate is much higher and smoother overall as you can see below in the video courtesy of our livestreamer Sin (believe me you don’t want to see my attempt): Watch video on YouTube.com To be clear, that video was recorded using my hardware on Ubuntu 19.04. There is at least two caveats though, which I will briefly go over. Firstly, it still needs to build up a decent cache first to not stutter. You can easily find out if DXVK is still building this cache, by adding “DXVK_HUD=pipelines” as a launch option, like this in Lutris as an example: When it stutters, you will see the "Graphics pipelines" counter increasing which will look something like this: The problem with the stuttering, is that Overwatch has a lot as you can see above. Comparatively, a game like Deep Rock Galactic has less than 2,000 (an entire 30-minute game only just went above 1,000). Which explains why Overwatch takes a little while to actually become super smooth. Once you’ve built up the cache though, simply getting to the main menu in Overwatch will have them all loaded in quite quickly ready for you to jump into a game. The other issue, is that Left Control cannot be bound to crouch. Other than those two issues I haven’t personally seen any others for some time and to me that’s pretty incredible really. So for those of you who do love Overwatch, it does seem to work very nicely on Linux and even better than ever in fact in my own testing through many hours. For those perhaps on the fence about trying Linux, at least Overwatch is one game you don’t have to really worry about losing and that’s important. Anything that can lower the barrier for people gaming on Linux, is great. Great work to everyone involved in Wine, DXVK and Lutris (I’m noting Lutris, since it makes managing it all together under one roof super simple).

2019-05-22 13:53:47

News briefs for May 22, 2019. The Antergos Linux distro is calling it quits. The developers of the Arch-based distro say they no longer have time to maintain it properly, and are taking the action now while the code is still working in case other developers want to start their own projects with it. From the Antergos blog: "For existing Antergos users: there is no need to worry about your installed systems as they will continue to receive updates directly from Arch. Soon, we will release an update that will remove the Antergos repos from your system along with any Antergos-specific packages that no longer serve a purpose due to the project ending. Once that is completed, any packages installed from the Antergos repo that are in the AUR will begin to receive updates from there." HP Linux Imaging and Printing (HPLIP) software has been updated to version 3.19.5 for Linux-based OSes. According to Softpedia News, this new release of the open-source and free print, scan and fax driver solution for HP printers and scanners supports "a plethora of new HP printers" (too many to list here), and it also brings support for several new distros, such as "Ubuntu 19.04 (Disco Dingo), Debian GNU/Linux 9.8, and Fedora 30". See the official HPLIP 3.19.5 Release Notes for more information. Kali Linux announces its second release of the year, Kali Linux 2019.2. This release "brings our kernel up to version 4.19.28, fixes numerous bugs, includes many updated packages, and most excitingly, features a new release of Kali Linux NetHunter!"

Bringing the Benefits of Linux Containers to Operational Technology

2019-05-22 12:30:00

by Pavan Singh Linux container technology was introduced more than a decade ago and has recently jumped in adoption in IT environments. However, the OT (operational technology) environments, typically made up of heterogenous embedded systems, have lagged in the adoption of container technologies, due to both the unique technology requirements and the business models that relied on proprietary systems. In this article, I explore recent innovation in open-source offerings that are enabling the use of containers in OT use cases, such as industrial control systems, IoT gateways, medical devices, Radio Access Network (RAN) products and network appliances. Enterprise IT leaders have adopted “cloud-native” computing architectures because of the innovation velocity and cost benefits derived by the approach. To leverage containers, developers segment applications into modular micro-services that enable flexible development and deployment models. These micro-services are then deployed as containers where the service itself is integrated with the required libraries and functions. On containerization, these application components have small footprints and fast speeds of deployment. The applications become highly portable across compute architectures due to the abstraction away from the hardware and the operating system. The benefits of flexibility and the modularity offered by container-based architectures are fully realized when leveraged in conjunction with higher-level orchestration systems that can manage the containers throughout their entire lifecycle. Kubernetes, the leading open-source orchestration system for containers, has gained a lot of traction over the last few years. Initially developed by Google, the Kubernetes project is now maintained by the Cloud Native Compute Foundation (CNCF). CNCF is dedicated to reducing the friction around the adoption of cloud-native technologies and brings to bear a few key cloud-native projects, such as Kubernetes, Prometheus and Envoy. This is an example of an open-source organization that has fostered collaboration among the entire value chain – developers, end-users and vendors. Today’s CNCF membership includes significant technology brands, such as Amazon, Cisco, Google, Microsoft, Oracle, SAP and many others. Containers and other cloud-native paradigms were initially developed with IT environments in mind. And as these technologies have matured and the capability of the cloud-native technologies increased, the OT decision-makers have taken notice. And as more developers get access to container technology, they are going through a journey of their own, albeit one that is different from the journey of the IT developers over the last decade.

The absolutely insane and pretty awesome twin-stick shooter 'BulletRage' is now on Kickstarter

2019-05-22 11:41:34

Tags: Action, Indie Game, Crowdfunding, Twin-stick shooter, DemoBulletRage is a game I firmly think is worth supporting, as the developer has had Linux support in very early and it does seem like a pretty awesome twin-stick shooter. BulletRage is a non-stop adrenaline twin-stick arcade shooter with 4 players Online and Local Co-op and PvP. Customize millions of weapon combinations, Handcrafted story levels, Random Dungeons, Twitch Extension, 5 difficulty modes and lots more. Dash and smash swarms of deadly enemies, using overwhelming firepower with insane power-ups. It's one I talked a little about before, as I was seriously impressed by the preview build I played back in February. I've tested it again recently and still firmly feel the same, it's absolutely insane and a ridiculously good time if you like a twin-stick shooter. Their Kickstarter campaign went live yesterday (which I somehow missed) with a goal of $68K Canadian Dollars. As usual for crowdfunding, if they hit over their goal they have some stretch-goals for additional game modes. Watch video on YouTube.com Interestingly, BulletRage has already been in development for three years. They're doing the campaign now, as they think it's in a state that they're ready for more people to jump in and actually see it for themselves. With that in mind, the demo is also now public and it's up on itch.io. For the full launch, they're saying it will cost around $20 and it will feature cross-platform multiplayer. You can find the Kickstarter campaign here if you're interested.

Update 28 was released just recently, giving it an overhaul in a few places. The biggest change is their update from the Unity game engine 5.1.3 to a much more modern 5.6.7. They say this allows them to bring in performance and optimization updates, lighting improvements, shader upgrades, deferred rendering, PBR materials support and so on. Lots of fancy new graphical features are available to them. You can see some of the enhancements in the below video: Watch video on YouTube.com Going over their changelog, they added Linux editor support for those contributors helping to keep it alive that work on Linux machines, an option to adjust motion blur amount, a new "Upper management" map in the playground mode, basic lean mechanics, weapons get blocked while leaning and and corners - so no more shooting through walls along with various other improvements and bug fixes. I am glad it's still alive, as it does continue to be promising. When you actually manage to get into a game and play with others in co-op or the traditional online modes, it can be a serious amount of fun. Especially with the dynamic maps, something not seen in a lot of first-person shooters even now. Sadly many have felt burned by the obvious lack of progress when the developer originally ran out of funding. You can find Interstellar Marines on Humble Store and Steam in Early Access.

Production of more than 250,000 chips embedded within fibers in less than a year

In the summer of 2018, a team led by MIT researchers reported in the journal Nature that they had successfully embedded electronic devices into fibers that could be used in fabrics or composite products like clothing, airplane wings, or even wound dressings. The advance could allow fabrics or composites to sense their environment, communicate, store and convert energy, and more.

Intel Icelake Brings New Top-Down Performance Counters

2019-05-22 11:09:27

While the Linux support for Intel's long awaited Icelake support has been out there for months and all fundamentals seemingly mature, there have been a few last-minute additions around some non-essential functionality. One of the latest Linux kernel patch series around Icelake is adding support for new Top-Down performance counters for these next-generation Intel processors...

Valve working on a stand-alone version of the popular Dota Auto Chess

Tags: Valve, Coming Soon, Steam, StrategyDota Auto Chess, a very popular custom game mode for Dota 2 is being turned into a stand-alone game by Valve. The Dota 2 arcade is full of interesting games but nothing has really come close to Dota Auto Chess, looking at it right now it has over 125K people playing just this one game mode. It also has over 8 million people subscribed to it, to give you another idea of just how popular it is. Based on player-count, if it manages to keep it for the stand-alone version it would put it into the top-5 games on Steam. Originally created by Drodo, Valve actually invited them to their offices back in February to see if they "want to collaborate directly with us". Seems it didn't work out, as Valve said in the blog post "we both came to the conclusion that Valve and Drodo could not work directly with each other for a variety of reasons". So instead, both Valve and Drodo are working on their own stand-alone version of the game while supporting each other. A group at Valve is now at work to make it, with more information about it to be shared "soon". You can find the original announcement here. It's interesting to see Valve getting back into making games, especially since Artifact flopped pretty hard and they're now revamping it (or so they say). They also have a big VR game coming up sometime this year that was teased before and now Dota Auto Chess. Hopefully they will eventually remember Left 4 Dead, Portal and Half-Life… I'm quite interested myself, I like the idea of Dota Auto Chess so to have a proper stand-alone version with a decent tutorial would be very nice.
