Zorin OS 15.1 is Released: A Better Way to Work, Learn and Play

2019-12-12 21:51:25

Just over 6 months ago, we launched Zorin OS 15, our most advanced and refined operating system ever. Since then, it’s been downloaded over 550,000 times around the world. Over 65% of these downloads were coming from Windows and macOS, reflecting our mission to bring the power of Linux to people who’ve never had access to it before. We would like to take this opportunity to thank every one of you for making this release as big and impactful as it has been. Today, we’re excited to announce that Zorin OS is getting even better with the release of version 15.1. We’ve paid close attention to your feedback and worked hard to make the desktop experience better for work, learning, playing, and everything in between. We’ve focused on making the desktop feel even more familiar and user-friendly to new users, especially those moving away from Windows 7 leading up to the end of its support in one month.

Why secure web-based applications with Kali Linux?

2019-12-12 21:40:40

The security of web-based applications is of critical importance. The strength of an application is about more than the collection of features it provides. It includes essential (yet often overlooked) elements such as security. Kali Linux is a trusted critical component of a security professional’s toolkit for securing web applications. The official documentation says it is “is specifically geared to meet the requirements of professional penetration testing and security auditing.“ Incidences of security breaches in web-based applications can be largely contained through the deployment of Kali Linux’s suite of up-to-date software. read more

The Zorin OS community has announced today the general availability of the Zorin OS 15.1, the first point release of their latest Zorin OS 15 operating system series based on Ubuntu 18.04 LTS. Coming six months after the release of Zorin OS 15, Zorin OS 15.1 is the first major update to the open-source and free computer operating system, based on Canonical's latest Ubuntu 18.04.3 LTS (Bionic Beaver) operating system, which means that it now ships with the Linux 5.0 kernel.

Fully supported Unity Editor for Linux delayed, Unity 2019.3 in the final testing stages

2019-12-12 19:45:42

Tags: Game Engine, Delayed, Unity, Upcoming, AppsTwo bits of big news about the Unity game engine to share today, one specifically about Linux and one about the Unity engine as a whole. Firstly, remember the team at Unity announced back in May that the Unity Editor for Linux was going to be fully supported instead of staying experimental? Well, sadly the release date slipped. Still happening though! In an update to the original blog post announcing it, they said it's been pushed from 2019.3 and so it's now happening in 2020. No exact date or version number for when it happens is being given. When we get more news about the Unity Editor getting a date again to move from experimental to supported, we will let you know. Why though? Well, that's the other bit of news. Unity 2019.3 is taking quite a bit longer than expected, as they announced today that it's such a big and complex release that they "want to ensure all these tools work well together before the release leaves the beta testing phase". So Unity 2019.3 will fully release sometime in January 2020. The big thing about Unity 2019.3 for game developers and Linux gamers is that this release will be the first to officially support IL2CPP on Linux which the lack-of has caused issues for some developers. Will be nice to have us back on some more feature parity with the Unity game engine.Article from GamingOnLinux.com

Try multiple upcoming Linux games like CARRION and SkateBIRD for 48 hours during The Game Awards

2019-12-12 18:59:53

Tags: Demo, Steam, Humble Store, Game SaleThe Game Awards is back and so Steam is doing a Game Festival to go along with it, with multiple upcoming games putting up a special limited-time demo. There's also sales, again. You might want to be quick, as the demos are only valid until December 13 at 6PM UTC. Below are the games that have a Linux demo available to try out. Spiritfarer - a cozy management game about dying. You play Stella, ferrymaster to the deceased, a Spiritfarer. Build a boat to explore the world, then befriend and care for spirits before finally releasing them into the afterlife. CARRION - a reverse horror game in which you assume the role of an amorphous creature of unknown origins, stalking and consuming those that imprisoned you. This one we actually took a look at before, seriously impressive! The Drifter - a 2d point and click adventure in the classic style. Taking cues from the recent revival of the genre there is an emphasis on story, with puzzle solving being the glue that ties it together rather than the focus. SkateBIRD - You're a lonely lil' bird, and your Big Friend has hung up their board for good. Their job sucks, and lately, they're barely ever home to play with you. You're gonna fix all that with the power of being a chill little skateboarding bird. Look, you're a cute little bird on a skateboard, do you need to know much more than that? I think out of any of these, CARRION is easily my favourite. They're all great though and pleasing to see such high quality fun titles continue to release for Linux and do early demos like this for us too. Curiously, System Shock from Nightdive Studios also has a Linux/SteamOS icon for the demo even though it's not supposed to, as Nightdive confirmed to GOL previously so that must be an error. System Shock will have a Linux version at release, just not for this demo. Still reading this far? Didn't run to try out one of those games? Okay, well, there's more brand new sales going on to celebrate all this too. Humble Store just put up their "Game Awards Sale 2019" (runs until Dec 16) as did Steam (runs until tomorrow).Article from GamingOnLinux.com

Build and manage a totally scientifically inaccurate Beehive in Hive Time, out now

2019-12-12 16:58:41

Tags: Indie Game, New Release, Strategy, Simulation, Godot EngineIt might not be scientifically accurate but Hive Time is a very sweet and relaxing little management sim. Disclosure: Cheese, the developer, is a contributor here on GOL. Keep busy Bees, grow your hive, make some sweet honey and produce a new Queen before your current one dies of old age. That's mostly the aim of the game in Hive Time, with colourful visuals and a family friendly theme encased in a sublime soundtrack from Peter Silk it's quite lovely overall. Watch video on YouTube.com More about it: Manage different bee roles in a totally scientifically inaccurate depiction of hive dynamics. Send Foragers out to find pollen and nectar, have Builders research new cell types, and ensure you have enough Beesitters to raise the next generation of bees. Make interesting choices that affect the hive. Respond to wasp attacks, deal with outlaw slugs, or help a caterpillar realise a lifelong dream. There's a nice bit of friendly humour sprinkled throughout it too. As you progress, your workers give you little messages, some of which are truly ridiculous puns on TV shows and Movies but I will admit this one made me laugh a good bit. Naughty bee. It seems overly simple when you get going, but thankfully it does slowly expand as you research into a management and building sim that keeps you going for hours. At your own pace though, Hive Time doesn't rush you. Even though it's always against the clock to get a new Queen, you're given quite a long time to do so. Hive Time offers a unique take on the ways of Bee life, personally I found it very relaxing. You can pick Hive Time up now only on itch.io. The suggested price is $10, but they've gone for a pay-what-you-want model so you could try before you buy, plus it means if you're totally broke you can enjoy it too. As for the soundtrack, you can grab that here and 50% of the soundtrack proceeds go to the Bumblebee Conservation Trust charity. It's also another game made with Godot Engine, good to see more using it out in the wild.Article from GamingOnLinux.com

AMD have today released the Radeon RX 5500 XT

2019-12-12 16:44:39

Tags: AMD, Hardware, New ReleasePowered by AMD's newer 7nm RDNA architecture, the Radeon RX 5500 XT originally announced in October is now available aimed at the 1080p PC gaming market. With pricing starting around $169 USD/£159.95 GBP, here's the specifications they supplied for the AMD Radeon RX 5500 XT: Compute Units: 22 Stream Processors: 1,408 TFLOPS: Up to 5.2 GDDR6 (GB): 4GB/8GB Game Clock (MHz): 1,717 Boost Clock (MHz): "Up to" 1,845 Memory Interface: 128-bit You can find the rest of the info on AMD's press release here. If you want to see how the RX 5500 XT holds up on Linux, Phoronix took a look (AMD don't send GOL anything). Looks like it holds up well against the GeForce GTX 1650 SUPER. If you're after a reasonably good GPU, at a good price for some Linux 1080p gaming it looks like the Radeon RX 5500 XT is a pretty good choice. Makes sense to put out good cards for 1080p gaming, it's still the most widely used resolution. Valve's monthly Hardware Survey puts it at 64.63% and nothing else comes close. Our own user survey puts 1080p amongst Linux gamers at around 58.42% too.Article from GamingOnLinux.com

Games: Feral Interactive, Fantasy Strike, GNU/Linux as Gaming Platform

2019-12-12 16:02:05

Seems like Feral Interactive may have a few surprises for Linux in 2020 Porting studio Feral Interactive [Official Site] have already given Linux a lot of games and it sounds like more are coming. While this year they've already released Shadow of the Tomb Raider Definitive Edition, a Vulkan beta for Shadow of Mordor, Total War: THREE KINGDOMS and DiRT 4 plus plus big updates/expansions to Company of Heroes 2 and Total War: WARHAMMER II. Still to come is Life is Strange 2, which Feral previously teased to arrive sometime soon. Fighting game Fantasy Strike adds full cross-platform online play with PC and Consoles The very pretty fighting game Fantasy Strike from Sirlin Games just got a great update, enabling cross-platform online play between Linux/macOS/Windows and the Nintendo Switch and Playstation 4 consoles. Apply to all online modes including Casual and Ranked, find a match should be a lot easier now. You can also challenge or spectate others from your in-game friends list, which also works across all platforms too as you can add people from any platform based on tags. Looking towards other operating systems Learning a new operating system from scratch is a daunting experience for many people. Fortunately, there are a few Linux distributions that come with a Windows-like desktop environment such as a form of a star bar at the bottom. However, Windows and Linux operating on vastly different philosophies, to the way that they are organized to the way that the files are handled. Linux employs the traditional monolithic kernel and it provides a hierarchical view of the files. Because it is modular, most of the necessary drivers can be loaded and unloaded dynamically. One of the major appeals of Linux is that it is open-source, compared to Microsoft which is a closed and inaccessible environment. Windows is made for simple and out of the box use and directed toward inexperienced users, a reason why the OS has been adopted by so many people. Linux puts more emphasis on the user, who has the possibility of customizing the desktop environment to suit their needs. Windows also offer a few, but fairly limited customization options. The main reason why people avoid switching to Linux is their gaming habits. Linux is known for not playing well with most PC games. Most PC games are being developed with Windows as the main platforms with some companies providing Linux support sometime after the original release. Games that do not have a Linux release require third party compatibility applications to run Windows games. The major application that is used to play Windows games on Linux is Wine. The developers of Wine have specified that the software is not an emulator but more of a compatibility layer for Linux to run Windows programs, not just games. In the world of programming, Wine is considered a masterpiece and one of the greatest feats of open source development that allows most Windows binaries to run on Linux without relying on any of Microsoft’s dependencies. Most of the Wine resources are dedicated to running the complicated frameworks of various DirectX components. [...] Many people prefer to enjoy online gaming, especially casino games. The beauty of these games is that most are available and can be played directly in the browser. The default browser that Linux uses is Mozilla Firefox, which itself, is a powerful browser. Because online casinos are played directly in the browser, there is almost no difference between playing them on Linux and playing them in Windows. There are also casino games that can be downloaded with most of them being made to run only on Windows due to a large number of people using the OS. As mentioned before, to run most Windows software, players have the option to use WINE. However, since because playing the casinos using the browser, most people are better off sticking with that version. Many games from online roulette to poker, and other table games are available online. Almost all online casinos found online have the option to play instantly with no download required, which is why any OS that can run a browser is perfectly capable to run casino games. Linux has been around for a long time, but it was only in the last 10 years that people have started noticing the operating system becoming more friendlier and easy to learn. Besides the many desktop environments, customizability, community and growing compatibility of games, as well as more security, many have started the transition from Windows to Linux. read more

Servers: Kubernetes, SUSE and Red Hat

2019-12-12 15:49:27

Creating Kubernetes distributions Making a comparison between Linux and Kubernetes is often one of apples to oranges. There are, however, some similarities and there is an effort within the Kubernetes community to make Kubernetes more like a Linux distribution. The idea was outlined in a session about Kubernetes release engineering at KubeCon + CloudNativeCon North America 2019. "You might have heard that Kubernetes is the Linux of the cloud and that's like super easy to say, but what does it mean? Cloud is pretty fuzzy on its own," Tim Pepper, the Kubernetes release special interest group (SIG Release) co-chair said. He proceeded to provide some clarity on how the two projects are similar. Pepper explained that Kubernetes is a large open-source project with lots of development work around a relatively monolithic core. The core of Kubernetes doesn't work entirely on its own and relies on other components around it to enable a workload to run, in a model that isn't all that dissimilar to a Linux distribution. Likewise, Pepper noted that Linux also has a monolithic core, which is the kernel itself. Alongside the Linux kernel is a whole host of other components that are chosen to work together to form a Linux distribution. Much like a Linux distribution, a Kubernetes distribution is a package of core components, configuration, networking, and storage on which application workloads can be deployed. Linux has community distributions, such as Debian, where there is a group of people that help to build the distribution, as well as a community of users that can install and run the distribution on their own. Pepper argued that there really isn't a community Kubernetes distribution like Debian, one that uses open-source tools to build a full Kubernetes platform that can then be used by anyone to run their workloads. With Linux, community-led distributions have become the foundation for user adoption and participation, whereas with Kubernetes today, distributions are almost all commercially driven. The total cost of software-defined storage In the current economic climate, the cost of everything is often closely examined to be sure we’re not paying too much. However, many focus on just the cost of acquisition – the capital expenditure – as opposed to looking at the bigger picture – the total cost of ownership, or TCO. In the world of IT, it’s easy to forget that the cost of owning servers, networking and storage equipment is more than the purchase price of the hardware. The total cost also includes installation, software licenses, service, support, training and upgrades amongst other things. Red Hat Gets NIST Recertification for ‘Enterprise Linux’ Operating System; Paul Smith Quoted A Red Hat operating system offering has earned recertification that validates the platform's capacity to process sensitive information in line with National Institute of Standards and Technology requirements. Red Hat said Tuesday it renewed Federal Information Processing Standard 140-2 cryptography certification for the Enterprise Linux 7.6 software built to support agencies and organizations in government-regulated industries. read more

Supporting structures of wind turbines contribute to wind farm blockage effect

2019-12-12 15:32:43

Locking down your smart home with blockchain

2019-12-12 14:53:58

The concept of the smart home has been around for many decades, but it is only in recent years with the advent of the so-called "internet of things," IoT, that meters and monitoring, cameras, locking systems, heating systems, and entertainment and information devices, have led to many homes having some degree of genuine smartness. Of course, with connectivity and utility come security problems. For instance, a malicious third party might find access to the home's wireless network, reprogram the smart TV, turn up the heating, disable the air conditioning, or even open the front door and allow them to remove all your smart devices and redeploy them elsewhere.

Surface organometallic chemistry could open new paths for synthetic fuels and energy carriers

2019-12-12 14:30:01

To convert hydrocarbons into fuel, the petrochemical industry currently relies primarily on heterogeneous catalysts, which in most cases contain active metal sites with poorly defined structures. In recent years, however, an area of study known as surface organometallic chemistry (SOMC) has enabled the design and development of far more defined, so-called single-site catalysts, in which metal sites can be tailored to meet specific requirements.

Debian: Systemd and Astronomy

2019-12-12 14:21:58

Enrico Zini: Init systems documentation Systemd has an excellent reference documentation in its manpages, but it does a lot of things, and a reference documentation isn't the best starting point for getting introduced to them. I would like to see a bit more documentation of the kind that sits between a systemctl start|stop|status and the reference manpages. Things like simple HOWTO posts on how to get a simple job done, or high-level explanations of how some specific feature works. I put some of what I know and used (or wrote) into systemd/documentation, I'll try to add to it when I find more, and I encourage you to do the same. Debian Begins Vote On Supporting Non-Systemd Init Choices There’s detailed descriptions of every possibility on the Debian builders mailing checklist. “It is a non-secret vote,” the publish explains. “After the voting interval is over the main points on who voted what can be printed.” Astronomy! Starting in January of 2020, I will be joining the Data Management team (specifically the Science Quality and Reliability Engineering team) for the Large Synoptic Survey Telescope. There's a much longer description at the above Wikipedia link and also at LSST's own site, but the short version is that the mission of LSST is to survey the entire southern night sky about twice a week for ten years. This in turn will provide vast amounts of data that will be used to do wide-ranging research in astronomy. All of that data requires indexing and processing so that scientists can use it. The team I'm joining is applying current software engineering techniques (containers, Jupyter notebooks, continuous integration, and so on) to that problem. For me, this is an opportunity to return to the academic, non-profit world that's always been my first love. It's also an opportunity to learn a bunch of new things (astronomy, for the most obvious, and scientific research computing more generally, but also some areas of technology that I've never had enough time to explore). Even better, everything my new team does is free software and is developed on GitHub, which means I'll be returning to a job where free software is at the center of the work instead of an optional side project for which there's rarely time. read more

Programming: PHP, C++, Python and More

2019-12-12 14:17:58

Excellent Free Tutorials to Learn PHP PHP has been at the helm of the web for many years. It’s an extremely popular, interpreted scripting language that is ideally suited for web development in part because it has an approachable syntax and supports different operating systems. This language powers millions of web sites on the net and is extremely well supported by its user community. PHP is also used as a general-purpose programming language. PHP code can be executed with a command-line interface (CLI) and to implement standalone graphical applications. CLI PHP programs often automate common tasks such as testing, deployment, and application administration. The language offers a very complete set of object-oriented programming features as well as support for functional programming. The latest TIOBE Index (August 2019 at time of writing) ranks PHP in 8th place, behind Java, C, C++, C#, Python, Visual Basic .NET, and JavaScript. The language is released under a non-copyleft free software license / open source license. The latest stable version adds lots of new features. Intel's MKL-DNN/DNNL 2.0 Beta 3 Release Adds SYCL + Data Parallel C++ Compiler Intel's MKL-DNN Deep Neural Network Library (DNNL) that is open-source and catering to deep learning applications like Tensorflow, PyTorch, DeepLearning4J, and others is nearing its version 2.0 release. With DNNL 2.0 is now support for Data Parallel C++ as Intel's new language as part of their oneAPI initiative. MKL-DNN/DNNL 2.0 Beta 3 was released on Wednesday and to my knowledge is their first public test release of the forthcoming 2.0. Notable with DNNL 2.0 is supporting SYCL API extensions and interoperability now with SYCL code, the single-source C++-based programming language backed by The Khronos Group and a crucial to Intel's new oneAPI initiative. Watch this machine made out of Lego sort other Lego using AI Dubbed the “Universal Lego Sorting Machine” by its creator, Daniel West, it’s a pretty neat contraption that’s far more useful than any of the Lego science projects I used to make. The machine is apparently able to use AI to sort Lego into one of 18 different buckets at a rate of “about one brick every two seconds.” West says he trained the neural network that sorts the bricks using 3D images of Lego parts, and he says the network can learn to recognize any piece as long as there’s a 3D image to train on. Reactive programming, a new way of thinking Get to know Reactive Programming and Grace Jansen, co-author of a new O'Reilly report that introduces Reactive and Reactive Architecture. [...] At Devoxx Belgium, Grace gave a number of talks, including one about Reactive programming and the pitfalls, entitled “Reacting to the future of application architecture.” In the talk, she uses an analogy from biology, namely how bees live and function together. “I compare the behavior of bees with how we would like applications to function and meet the requirements and expectations of users.” Future-proof monolithic applications with modular design DevNation tech talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions and code and sample projects to help you get started. In this talk, you’ll learn about future-proofing applications from Eric Murphy and Ales Nosek, Architects with Red Hat Consulting. When building an MVP software application, you may immediately jump to a microservices architecture because it’s the new norm for building cloud-native applications. You may also be skeptical about starting off with a monolith because of the perception of such applications as relics of the past. Merge Sort in Python Merge Sort is one of the most famous sorting algorithms. If you're studying Computer Science, Merge Sort, alongside Quick Sort is likely the first efficient, general-purpose sorting algorithm you have heard of. It is also a classic example of a divide-and-conquer category of algorithms. Updates on Unoon in December 2019 This Saturday evening, I sat with Unoon project after a few weeks, I was continuously running it, but, did not resume the development effort.

IoT ugly Christmas sweaters If there’s one thing we Brits love, it’s an ugly Christmas sweater. Jim Bennett, a Senior Cloud Advocate at Microsoft, has taken his ugly sweater game to the next level by adding IoT-controlled, Twitter-connected LEDs thanks to a Raspberry Pi Zero. A Look at Ubuntu on MINIX NEO G41V-4 and J50C-4 Mini PCs iCommSemi SV6166F is a Low-Power WiFi SoC for IoT and Embedded Systems RISC-V Foundation Says Goodbye to the United States For over thirty years U.S. companies have enjoyed a home court advantage in developing information and communications technology (ICT) standards. Specifically, the overwhelming majority of the more than five hundred consortia founded over the last thirty-five years to develop ICT standards have been formed under U.S. laws and headquartered in the U.S. That’s hardly a surprise because the vast majority of the companies that founded these same consortia were also American companies. Now the times may be a-changing. The ability to form and maintain standards consortia in the founders’ backyards provides significant advantages. They include convenience, reduced travel costs, predictability of legal results, choice of language, demonstration of national leadership, standardization of governance structures and more. For decades, foreign companies were amenable to this practice, so long as a sufficient percentage of face to face meetings were held outside the U.S. That tolerance began to erode after 9/11. New security measures made crossing the U.S. border more tedious, sometimes even requiring fingerprinting as a precondition to entry. Some members couldn’t obtain visas at all, an issue that became more critical as Chinese companies became more active in standards development. Privacy concerns also escalated, leading to European objections to hosting the information of its citizens in the U.S. at all. Those concerns were temporarily abated when new rules were put in place, but anxieties have heightened again – this time with the U.S. as well as in Europe – over the privacy policies of the largest U.S. IT companies. This year, concerns increased again when ZTE, and then Huawei and scores of that Chinese company’s affiliates, were added to the U.S. “Entity List.” Huawei and its affiliates are reportedly members of over 400 ICT standards organizations, each of which was suddenly tasked with figuring out which of its activities, if any, it could now permit the Chinese companies to participate in. read more

Graphics: AMD, Intel, Vulkan/Flycast and NVIDIA

2019-12-12 13:20:22

AMD Publishes Vega 7nm ISA Documentation - 300 More Pages Of GPU Docs Beyond AMD's open-source graphics driver stack of the past decade, part of their original open-source plans have also involved providing public (NDA-free) GPU hardware documentation. That has come with time though the documentation drops are not coordinated in-step with code drops. Out today, for example, is the ISA documentation on Vega 7nm. Back in 2017 was the timely release of the Vega ISA documentation and earlier this summer was even the RDNA 1.0 ISA documentation but missing out until now was the Vega 7nm ISA documentation. Intel's Iris Gallium3D Driver Continuing To See Performance Optimizations On Mesa 20.0 With the current Mesa 19.3 there is the Intel Gallium3D driver generally performing much better than their "classic" i965 driver and for Mesa 20.0 it looks to only make more ground as it switches over to this driver by default. Beyond the recent build system changes for supporting an Intel Gallium3D default and building it as part of the default x86/x86_64 Gallium3D drivers with hopes of soon flipping the switch for Broadwell and newer, more performance optimizations are still being done. Dreamcast emulator Flycast adds a Vulkan renderer There seems to be quite a lot of interest in Vulkan lately, as more projects begin using it. Now we have the Dreamcast emulator Flycast adding Vulkan support. In the technical blog post announcing it on the Libretro site, it gives a bit of brief history of the Dreamcast GPU and mentions the usual "less overhead, more reliability and better performance in many cases" when it comes to using Vulkan although it's a lot more complicated to use. NVIDIA have two new Linux drivers available, one stable and one Vulkan Beta NVIDIA continue pushing their drivers forwards with two new Linux driver updates available. Let's take a quick look. First, the stable 440.44 driver release as part of their long-lived branch. This adds support for the Quadro T2000 with Max-Q Design, you can now use the "__GL_SYNC_DISPLAY_DEVICE" environment variable for Vulkan applications and it fixes a few bugs like tearing with a G-SYNC or G-SYNC Compatible monitor when you've got something running directly on a display (like VR). read more

Seems like Feral Interactive may have a few surprises for Linux in 2020

2019-12-12 13:02:32

Tags: Feral Interactive, Teaser, SpeculationPorting studio Feral Interactive [Official Site] have already given Linux a lot of games and it sounds like more are coming. While this year they've already released Shadow of the Tomb Raider Definitive Edition, a Vulkan beta for Shadow of Mordor, Total War: THREE KINGDOMS and DiRT 4 plus plus big updates/expansions to Company of Heroes 2 and Total War: WARHAMMER II. Still to come is Life is Strange 2, which Feral previously teased to arrive sometime soon. After that, we already know Feral is porting Total War Saga: TROY but what about more games, is that the end of it for Linux? Going by their replies to people on Twitter, like this one "We may have a few Linux games planned for 2020... ;)" they seem to indicate there may be some surprises for us next year. That's good news of course, since Steam Play/Proton was an obvious worry that they might stop porting. There's tons of games that are completely broken with Steam Play and plenty that perform really badly that Feral could certainly do their porting magic with. Actual support would be good too and Feral certainly know what they're doing. What game would you like to see Feral port to Linux and support? Hat tip to NuSuey.Article from GamingOnLinux.com

Taking the carbon out of construction with engineered wood

2019-12-12 12:53:37

To meet the long-term goals of the Paris Agreement on climate change—keeping global warming well below 2 degrees Celsius and ideally capping it at 1.5 C—humanity will ultimately need to achieve net-zero emissions of greenhouse gases (GHGs) into the atmosphere. To date, emissions reduction efforts have largely focused on decarbonizing the two economic sectors responsible for the most emissions, electric power and transportation. Other approaches aim to remove carbon from the atmosphere and store it through carbon capture technology, biofuel cultivation, and massive tree planting.

We added experimental support for Qt for WebAssembly and Qt for MCUs. We improved the general handling of configuring, building and running projects in so many smaller ways that I fail to choose anything for being highlighted here. If you use CMake 3.14 or later we now use CMake's file-base API for configuring and parsing projects. Which behaves much more reliably than the previous server-mode, especially if you also use CMake from a terminal or other applications. read more

Fighting game Fantasy Strike adds full cross-platform online play with PC and Consoles

2019-12-12 12:40:55

Tags: Fighting, Steam, Indie Game, UpdateThe very pretty fighting game Fantasy Strike from Sirlin Games just got a great update, enabling cross-platform online play between Linux/macOS/Windows and the Nintendo Switch and Playstation 4 consoles. Apply to all online modes including Casual and Ranked, find a match should be a lot easier now. You can also challenge or spectate others from your in-game friends list, which also works across all platforms too as you can add people from any platform based on tags. Excellent, this is how more games with multiplayer should do it. Often there's no real technical reason why it shouldn't happen and it's great that console makers have finally woken up to this. It adds value! I love the characters in this game, the stretchy arms of Argagarg (try saying that three times quickly…) are quite amusing to fight with. This update that enables cross-play also fixes a bunch of bugs, you can see the patch notes here. One thing I do wish Fantasy Strike had was a built-in tournament mode, I always find those end up pulling me in when I can run and join community tournaments, always good fun. You can find the Linux version of Fantasy Strike on Steam.Article from GamingOnLinux.com

Games: Transport Fever 2, Vampire: The Masquerade - Coteries of New York, Rocket League

Build a transportation empire with Transport Fever 2 out now, same-day support for Linux Urban Games and Good Shepherd Entertainment are back, with Transport Fever 2 now officially available with same-day support for Linux. With a wide variety of transportation options available to build across multiple generations, there's a huge amount of content included. Prepare to kiss your time and friendships goodbye as we've got another great time-sink on our hands. Vampire: The Masquerade - Coteries of New York for Linux is now uncertain Before release, the store pages for Vampire: The Masquerade - Coteries of New York very clearly listed Windows, MAC OS, Linux and now it's only available for Windows. Not to be confused with Bloodlines 2, Coteries of New York is styled like an interactive fiction (a fancy way to say: Visual Novel). It does look good though and it sounded very interesting so we were quite excited to see the mention of Linux support. Rocket League's new Item Shop and Blueprints get a price reduction Oh Psyonix, what have you done? Rocket League recently had the loot boxes removed, with Blueprints and an Item Shop instead so you see exactly what you get but the pricing is terrible. As someone who has hundreds of hours in Rocket League, Psyonix really did disappoint with the big update recently. It could have been handled a lot better, but it came across as incredibly greedy. It's a game you have to pay for, yet they wanted us to spend a ridiculous amount of money on Credits for some of the items. read more

LibreOffice 6.3.4 available for download

2019-12-12 12:35:11

For enterprise class deployments, TDF strongly recommend sourcing LibreOffice from one of the ecosystem partners to get long-term supported releases, dedicated assistance, custom new features and other benefits, including Service Level Agreements (SLAs). Also, the work done by ecosystem partners flows back into the LibreOffice project, benefiting everyone. Also, support for migrations and trainings should be sourced from certified professionals who provide value-added services which extend the reach of the community to the corporate world and offer CIOs and IT managers a solution in line with proprietary offerings. In fact, LibreOffice – thanks to its mature codebase, rich feature set, strong support for open standards, excellent compatibility and long-term support options from certified partners – represents the ideal solution for businesses that want to regain control of their data and free themselves from vendor lock-in. read more

GNOME and gestures, Part 3: HdyLeaflet again

2019-12-12 12:31:01

0.0.12 brings some changes to HdyLeaflet mode and child transitions. Separate mode and child transition types have been deprecated in favor of a unified transition-type property. It can take 4 values: none, slide, over, under. Crossfade doesn’t make much sense spatially and was deprecated as well, though it’s still works if used via child-transition-type property. Additionally, over and under transitions have a subtle shadow now, similar to the WebKit gesture. It’s recommended that the apps using the gesture use over transition. read more

In the technical blog post announcing it on the Libretro site, it gives a bit of brief history of the Dreamcast GPU and mentions the usual "less overhead, more reliability and better performance in many cases" when it comes to using Vulkan although it's a lot more complicated to use. They said Vulkan support in Flycast works across Linux, Windows and Android and it should already be on par with the OpenGL renderer "with the notable exception of lightgun crosshair and VMU screens display, which will be added soon". According to the post, the newest Nightly build should have Vulkan in which you can find and download the Flycast Core here. I actually had a Dreamcast! With some really fond memories of playing through Phantasy Star Online, Crazy Taxi, ChuChu Rocket!, Shenmue and various Sonic games. Being able to easily play some again on Linux thanks to Flycast and RetroArch is awesome.Article from GamingOnLinux.com

Apps Update for December

2019-12-12 11:22:04

Creating new applications is the easy part. Maintaining them, making them safer and faster and adding features that make them more useful to users is what marks the difference between one-shot wonders and solid tools you can trust and enjoy for years. That is why KDE developers are constantly renewing and updating their applications, making them more reliable, more useful, and in general, just better. What follows is just a minor sample of what you can expect from the latest round of updates for applications made by the KDE community over the last month: Calligra Plan is Back Calligra Plan lets you plan your projects in detail. Calligra Plan, KDE's project planning and management tool, gets its first big update in two years. In case you were not aware, Plan helps you manage small and large projects which require multiple resources. In order for you to model your project, Plan offers different types of task dependencies and timing constraints. You can define your tasks, estimate the effort needed to perform each, allocate resources and then schedule the project according to your needs and the actual resources available. One of Plan's strengths is its excellent support for Gantt charts. Gantt charts help you plan, coordinate, and track specific tasks in a project. Using Gantt charts in Plan you will be able to better monitor your project's workflow. Kdenlive Pumps up the Volume Kdenlive rocking a brand new audio mixer. Kdenlive developers have been adding new features and squashing bugs like crazy -- the latest version alone comes with more than 200 changes. A lot of work has gone into improving support for audio. In the "bugs solved", department they have gotten rid of an error that would eat up memory. They have also made saving audio thumbnails much more efficient. But the most exciting new feature is that Kdenlive now comes with a spectacular sound mixer (see image). Developers have also added a new audio clip display in the clip monitor and the project bin so you can better synchronize your moving images with the soundtrack. Für Elisa Talking of sound, Elisa is one of KDE's most popular up-and-coming music players. Elisa belongs to the deceptively simple, very light, very good-looking variety of players, with an intuitive and elegant interface and, in its latest version, Elisa has upgraded its looks even further to adapt better to High DPI screens. It also now integrates better with the looks other KDE applications. Indexing music files has also improved and Elisa now supports web radios and comes with a few examples for you to try. The Elisa music player. KDE Connect: Let Your Phone Rule your Desktop KDE Connect now lets you controlthe global volume of your system. Most people who get to know KDE Connect, end up raving about it just because of how darned useful it is. The latest version of KDE Connect packs even more features. One of the more noticeable is that there is a new SMS app that lets you read and write SMS from your computer with the full conversation history. Developers are also adding new functionalities to existing features to make them even more useful. For example, you could already use KDE Connect to control the volume of media playing on your desktop, say, in VLC. But now you can use KDE Connect to also control your system's global volume from your phone. When giving a talk, you can control your presentation using KDE Connect to flip forward and back through your slides, and apart from integrating with other KDE apps, you can now also send files from Thunar (Xfce's file manager) and Elementary applications such as Pantheon Files. Talking of other platforms, you can now run the mobile component of KDE Connect not only on Android, but also on all those mobile Linux platforms we'll be seeing in upcoming devices like the PinePhone and the Librem 5. The new version also provides features for desktop-to-desktop users, such as media control across desktops, remote input, device ringing, file transfers and running commands. And Much More But that is not all by any means: Dolphin, Spectacle, Okular and dozens of other applications have included new features you are sure to find useful. Even more projects, broaching apps, libraries and frameworks, have tweaked their code making them more stable and secure. If you want to get an idea of the full range of changes, visit the official release announcement, or check out the changelog for every single detail of what has changed. Getting applications made by KDE is also now easier: most are now available as Flatpaks, Snaps and AppImages. You just have to download them and they run straight out of the box. Many programs are also available for more platforms, such as Android, macOs and Windows. Krita and Okular have been available in the Microsoft Store for some time now, and they have recently been joined by Kile, a user-friendly LaTeX document editor. Distributions will be updating their own repos and making the new versions available to Linux users over the next few weeks. Look out for your updates!

Rocket League's new Item Shop and Blueprints get a price reduction

2019-12-12 11:17:30

Tags: Sports, Steam, Humble Store, UpdateOh Psyonix, what have you done? Rocket League recently had the loot boxes removed, with Blueprints and an Item Shop instead so you see exactly what you get but the pricing is terrible. As someone who has hundreds of hours in Rocket League, Psyonix really did disappoint with the big update recently. It could have been handled a lot better, but it came across as incredibly greedy. It's a game you have to pay for, yet they wanted us to spend a ridiculous amount of money on Credits for some of the items. Yesterday, they put out a news post to discuss it and they've made some changes. The base price of rarities and the specials have been reduced down to: Rare: 50-100 Credits Most Paint Colors: 50-200 additional Credits Very Rare: 100-200 Credits Burnt Sienna: 0 additional Credits Import: 300-500 Credits Titanium White: 100-500 additional Credits Exotic: 700-800 Credits Special Editions: 200-400 additional Credits Compare with the actual price of Credits again (which haven't changed): 500 Credits - £3.84 1100 Credits - £7.69 3,000 Credits - £19.23 6,500 Credits - £38.48 Taking the changes into account, the Painted Car Body I showed off in the previous article has been reduced from 1,000 to 700 Credits as just one example of it making quite a big difference in the cost. Well, it's a little less terrible now. Still not good enough overall though, just to put this point through enough this is a paid game. If it goes free to play, fair enough (and I expect it to next year) but at those prices they're still likely not going to pull much in as it's painfully high for single cosmetic items. If you could perhaps convert a bunch of unwanted Blueprints into Credits, it would be slightly less terrible again. I fully expect plenty more drama around this as they continue to tweak it. Rocket League is available from the Humble Store and Steam.Article from GamingOnLinux.com

NVIDIA have two new Linux drivers available, one stable and one Vulkan Beta

2019-12-12 10:27:04

Tags: NVIDIA, Drivers, Update, Vulkan, OpenGLNVIDIA continue pushing their drivers forwards with two new Linux driver updates available. Let's take a quick look. First, the stable 440.44 driver release as part of their long-lived branch. This adds support for the Quadro T2000 with Max-Q Design, you can now use the "__GL_SYNC_DISPLAY_DEVICE" environment variable for Vulkan applications and it fixes a few bugs like tearing with a G-SYNC or G-SYNC Compatible monitor when you've got something running directly on a display (like VR). What does "long-lived" mean? Here's what NVIDIA themselves said about it (source): Any given release branch is either long-lived or short-lived. The difference is in how long the branch is maintained and how many releases made from each branch. A short-lived branch typically has only one or two (non-beta) releases, while long-lived branches will have several. On top of that there's a new Vulkan Beta Driver 440.43.01, which has now been re-based to the 440 release branch with all the recent changes and improvements since the 435 re-base in August. On top of that it also fixes rendering to 3D depth/stencil image slices, various resource leaks and improves the Vulkan driver startup time. As a reminder, NVIDIA have a possibly very interesting talk next year which may contain some open source announcements and future plans. It's going to be exciting to find out more!Article from GamingOnLinux.com

Vampire: The Masquerade - Coteries of New York for Linux is now uncertain

2019-12-12 10:14:06

Tags: RPG, Visual Novel, Steam, GOG, Indie GameBefore release, the store pages for Vampire: The Masquerade - Coteries of New York very clearly listed Windows, MAC OS, Linux and now it's only available for Windows. Not to be confused with Bloodlines 2, Coteries of New York is styled like an interactive fiction (a fancy way to say: Visual Novel). It does look good though and it sounded very interesting so we were quite excited to see the mention of Linux support. Originally, both Steam and GOG listed it as this: Coteries of New York will be available on PC (Windows, MAC OS, Linux) and Nintendo Switch. However, shortly before launch that was silently switched with no announcement to this: Coteries of New York will be available on PC (Windows only! We may add Linux and MAC OS later). The game will launch on PS4, Xbox One and Nintendo Switch in Q1 2020. To be confirmed, then suddenly only be a maybe is quite a big change. Frustrating when it's not communicated well either. Sadly the developer, Draw Distance, never replied to our emails before release. On Steam, their team did reply to a couple of forum posts asking about it. Here's what they said|: Hi guys, let me please explain the lack of Linux support: at launch day the Linux version is not supported unfortunately. We didn't want to release a version, which wasn't tested enough in our opinion. But, we'll look into the case and hopefully we'll be able to add the Linux support as soon as possible! Thank you for your understanding and sorry for inconvenience! Jacek Głowacki, Draw Distance If you're interested you can follow it on GOG and Steam. Hopefully they will still support Linux with it, will let you know if the situation changes.Article from GamingOnLinux.com

How to configure Openbox for your Linux desktop

2019-12-12 08:02:00

You may have used the Openbox desktop without knowing it: While Openbox is a great window manager on its own, it also serves as the window manager "engine" for desktop environments like LXDE and LXQT, and it can even manage KDE and GNOME. Aside from being the foundation for several desktops, Openbox is arguably one of the easiest window managers to configure for anyone who doesn't want to learn all the options to put into a config file. read more

How to replace a hard drive on Linux

Fedora and Red Hat: Fedora's Modularity Initiative, Git, Servers, Buildah and Ansible

2019-12-12 04:07:47

Fedora's modularity mess Fedora's Modularity initiative has been no stranger to controversy since its inception in 2016. Among other things, there were enough problems with the original design that Modularity went back to the drawing board in early 2018. Modularity has since been integrated with both the Fedora and Red Hat Enterprise Linux (RHEL) distributions, but the controversy continues, with some developers asking whether it's time for yet another redesign — or to abandon the idea altogether. Over the last month or so, several lengthy, detailed, and heated threads have explored this issue; read on for your editor's attempt to integrate what was said. The core idea behind Modularity is to split the distribution into multiple "streams", each of which allows a user to follow a specific project (or set of projects) at a pace that suits them. A Fedora user might appreciate getting toolchain updates as soon as they are released upstream while sticking with a long-term stable release of LibreOffice, for example. By installing the appropriate streams, this sort of behavior should be achievable, allowing a fair degree of customization. Much of the impetus — and development resources — behind Modularity come from the RHEL side of Red Hat, which has integrated Modularity into the RHEL 8 release as "Application Streams". This feature makes some sense in that setting; RHEL is famously slow-moving, to the point that RHEL 7 did not even support useful features like Python 3. Application Streams allow Red Hat (or others) to make additional options available with support periods that differ from that of the underlying distribution, making RHEL a bit less musty and old, but only for the applications a specific user cares about. The use case for Modularity in Fedora is arguably less clear. A given Fedora release has a support lifetime of 13 months, so there are limits to the level of stability that it can provide. Moving bugzilla overrides to dist-git A while ago Fedora had pkgdb to configure ACLs for each package repo and package related admin actions. When we moved to 'pagure over dist-git', pagure already provided some of these capabilities. pkgdb would have needed a lot of effort to make it work with the modern package branching (modularity) [1] with different lifecycles for each package that are unrelated to Fedora releases and thus we've decided to retire it and replace it with a different solution. One of the missing parts after retireing pkgdb was the ability to set different default bugzilla assignees for EPEL and Fedora. This was solved by creating a new repository called fedora-scm-requests [2]. A script would then parse the contents of the repository, merge that information with the main package admins and repo watchers from dist-git and sync this information to bugzilla so that new bugs get assigned to the correct maintainers and all the interested parties get put on CC:. Each change required a pull request to this repo and someone from the infrastructure team to review and merge the patch. It is obvious that this doesn't scale with the huge number of packages that Fedora and EPEL have. Red Hat customers want the hybrid cloud If you listen to some people, everyone and their corner office wants to move to the public cloud. Red Hat's global customers have a different take. Thirty-one percent of Red Hat's customers say "hybrid" describes their strategy best, 21% are leaning toward a private cloud approach, while only 4% see the public cloud as their first choice. There's only one little problem: Finding the staff with the right skills to make the jump from old-school IT to the cloud. Businesses prefer the hybrid cloud strategy for many different reasons -- but, overall, data security, cost benefits, and data integration led the pack. For years, the hybrid cloud wasn't that popular. With the rise of the Kubernetes-based hybrid cloud model and with Red Hat being one of the new-model hybrid cloud's leading proponents, customers are embracing the hybrid cloud.

Kernel: LWN Articles and Radeon Linux 5.6 Changes

2019-12-12 03:37:08

Fixing SCHED_IDLE The scheduler implements many "scheduling classes", an extensible hierarchy of modules, and each class may further encapsulate "scheduling policies" that are handled by the scheduler core in a policy-independent way. The scheduling classes are described below in descending priority order; the Stop class has the highest priority, and Idle class has the lowest. The Stop scheduling class is a special class that is used internally by the kernel. It doesn't implement any scheduling policy and no user task ever gets scheduled with it. The Stop class is, instead, a mechanism to force a CPU to stop running everything else and perform a specific task. As this is the highest-priority class, it can preempt everything else and nothing ever preempts it. It is used by one CPU to stop another in order to run a specific function, so it is only available on SMP systems. The Stop class creates a single, per-CPU kernel thread (or kthread) named migration/N, where N is the CPU number. This class is used by the kernel for task migration, CPU hotplug, RCU, ftrace, clock events, and more. The Deadline scheduling class implements a single scheduling policy, SCHED_DEADLINE, and it handles the highest-priority user tasks in the system. It is used for tasks with hard deadlines, like video encoding and decoding. The task with the earliest deadline is served first under this policy. The policy of a task can be set to SCHED_DEADLINE using the sched_setattr() system call by passing three parameters: the run time, deadline, and period. To ensure deadline-scheduling guarantees, the kernel must prevent situations where the current set of SCHED_DEADLINE threads is not schedulable within the given constraints. The kernel thus performs an admittance test when setting or changing SCHED_DEADLINE policy and attributes. This admission test calculates whether the change can be successfully scheduled; if not, sched_setattr() fails with the error EBUSY. The POSIX realtime (or RT) scheduling class comes after the deadline class and is used for short, latency-sensitive tasks, like IRQ threads. This is a fixed-priority class that schedules higher-priority tasks before lower-priority tasks. It implements two scheduling policies: SCHED_FIFO and SCHED_RR. In SCHED_FIFO, a task runs until it relinquishes the CPU, either because it blocks for a resource or it has completed its execution. In SCHED_RR (round-robin), a task will run for the maximum time slice; if the task doesn't block before the end of its time slice, the scheduler will put it at the end of the round-robin queue of tasks with the same priority and select the next task to run. The priority of the tasks under the realtime policies range from 1 (low) to 99 (high). Virtio without the "virt" One might ask why it makes sense to implement virtio devices in hardware. After all, they were originally designed for hypervisors and have been optimized for software rather than hardware implementation. Now that virtio support is widespread, the network effects allow hardware implementations to reuse the guest drivers and infrastructure. The virtio 1.1 specification defines ten device types, among them a network interface, SCSI host bus adapter, and console. Implementing a standards-compliant device interface lets hardware implementers focus on delivering the best device instead of designing a new device interface and writing guest drivers from scratch. Moreover, existing guests will work with the device out of the box, and applications utilizing user-space drivers, such as the DPDK packet processing toolkit, do not need to be relinked with new drivers — this is especially helpful when static linking is utilized. Implementing virtio in hardware also makes it easy to switch between hardware and software implementations. A software device can be substituted without changing guest drivers if the hardware device is acting up. Similarly, if the driver is acting up, it is possible to substitute a software device to make debugging the driver easier. It is possible to assign hardware devices to performance-critical guests while assigning software devices to the other guests; this decision can be changed in the future to balance resource needs. Finally, implementing virtio in hardware makes it possible to live-migrate virtual machines more easily. The destination host can have either software or hardware virtio devices. 5.5 Merge window, part 1 The 5.5 merge window got underway immediately after the release of the 5.4 kernel on November 24.

GNOME at the Back End and GNOME Shell 3.35.2

2019-12-12 03:27:54

Molly de Blanc: Keeping the (server) lights on Building and maintaining infrastructure for the GNOME project is one of the many activities of the GNOME Foundation, and it’s one of the most important. Building software like the GNOME desktop environment requires a lot of technical support, including managing servers and providing collaboration tools. Since GNOME is focused on being a self-sustaining community, we look as much as possible to managing our own services and software, and making sure it is free and open source. The GNOME Infrastructure Team currently supports a total of 34 virtual machines hosted on a total of eight bare metal nodes. These virtual machines allow us to run services like the Openshift Container Platform (OSCP), which provides self-service access to the community to run any of their workflows on an automated and containarized fashion. GNOME is build using self-hosted FOSS. We collaboratively build GNOME using a GitLab instance, which has a total of 15k accounts. We do shared storage using NextCloud. Community discussion is handled over Mailman, Discourse, and MoinMoin. We are currently using Indico and Connfa for our event planning and management. GNOME Shell 3.35.2 Begins Launching Spawned Processes Within Systemd Scopes Out today is a new development release of GNOME Shell on the road to GNOME 3.36 in March. Among the changes in this new GNOME Shell snapshot include: - Spawned processes are now placed within systemd scopes in order to improve out-of-memory behavior for applications, an easy means of being able to kill other processes when the shell is restarted, and other use-cases. Systemd scopes allow managing of processes for organization and resource management purposes. read more

Security: Proprietary Software Holes and More

2019-12-12 03:22:45

It's the end of the 20-teens, and your Windows PC can still be pwned by nothing more than a simple bad font With the year winding to a close and the holiday parties set to kick off, admins will want to check out the December Patch Tuesday load from Microsoft, Adobe, Intel, and SAP and get them installed before downing the first of many egg nogs. [...] Also of note is CVE-2019-1471, a critical hypervisor escape bug that would allow an attacker running on a guest VM to execute code on the host box. The bulk of this month's critical fixes were for a series of five remote code execution flaws in Git for Visual Studio. In each of the flaws, said to be caused by improper handling of command-line input, an attacker would launch the exploit by convincing the target to clone a malicious repo. The remaining critical patch is for CVE-2019-1468, a play on the tried-and-true font-parsing vulnerability. In the wild, an attacker would embed the poisoned font file in a webpage and attack any system that visits. Exploring Legacy Unix Security Issues The operating system SGI IRIX 6.5.22 was declared end of life in 2003, so it has limited use as a production system. I decided I could relive the good old days by looking for new vulnerabilities on an old system in my spare time. It was also an excuse to write some C code, and refresh my memory. One of my favorite vulnerabilities is the Insecure Temporary File (CWE-377). This involves manipulating files created in /tmp in an insecure manner. A file is created in /tmp by a piece of software that doesn’t check if the file exists before creating it. Allowing a malicious local user to symlink that file to a critical system file and overwriting it with the contents of what is written to the file in /tmp. So I started looking under the /usr/sbin directory for binaries to target. I did a quick examination of binaries and scripts in using the find command to give myself a starting point. Private Internet Access updates Linux desktop client to prevent against [CVE-2019-14899] The Breakpointing Bad team at the University of New Mexico recently reported a VPN vulnerability that affects Linux, MacOS, iOS, Android, and more. The vulnerability allows malicious actors to not only see your VPN IP address, but also identify sites you are visiting and inject data into connections. The team consists of William J. Tolley, Beau Kujath, and Jedidiah R. Crandall and the public was notified on December 4th, 2019. Designated [CVE-2019-14899], the vulnerability shook the VPN industry due to the breadth of affected systems. [CVE-2019-14899] affects many different types of VPN protocols including OpenVPN, WireGuard, and IKEv2/IPSec. Private Internet Access has released an update to its Linux client that mitigates [CVE-2019-14899] from being used to infer any information about our users’ VPN connections. To our knowledge, Private Internet Access is the first commercial VPN to release a new client that prevents this ongoing security vulnerability. Chrome now warns you when your password has been stolen Google is rolling out Chrome version 79 today, and it includes a number of password protection improvements. The biggest addition is that Chrome will now warn you when your password has been stolen as part of a data breach. Google has been warning about reused passwords in a separate browser extension or in its password checkup tool, but the company is now baking this directly into Chrome to provide warnings as you log in to sites on the web. read more

8 of the worst open source innovations of the decade

2019-12-11 22:24:59

Over the years, Linux and open source have been a master class on slow burn success. From out of nothing, Linux has become the champion of the cloud, IoT, and containers. And although it hasn't reached the "world domination" status it swore in the early 2000s, Linux desktop is still very much alive and building momentum. But that doesn't mean it's been all success; in fact, there have been a few stumbles along the way. Let's take a look at some of the worst open source failures of the decade. read more

9 of the biggest open source stories in 2019

2019-12-11 22:21:51

The year is 2019. Although cries of "world domination" still echo in the hallowed halls of Linux land, everyone knows this great event will have to wait for another year, but that doesn't mean all those who are invested in open source need to hang their heads in shame. Failure was never an option, and it wasn't an issue--not in the year of subtle takeover. If I have to give 2019 a title for open source, it is just that--subtle takeover. Why? Because subtle things happened, many of which will have reverberations for years to come. Let's take a look at the some of the moments that defined the year for Linux and open source. read more

Build a transportation empire with Transport Fever 2 out now, same-day support for Linux

2019-12-11 21:51:51

Tags: New Release, Humble Store, GOG, Steam, Strategy, SimulationUrban Games and Good Shepherd Entertainment are back, with Transport Fever 2 now officially available with same-day support for Linux. With a wide variety of transportation options available to build across multiple generations, there's a huge amount of content included. Prepare to kiss your time and friendships goodbye as we've got another great time-sink on our hands. Watch video on YouTube.com Transport Fever 2 is a stylish transportation tycoon sim that gives you quite a lot of freedom to let your creative side flow. This is especially true thanks to the massively improved terrain shaping tools available to you, with the coastline and water no longer being a hard immovable border. You can now shape the terrain through the water, to completely change the shape or remove it all entirely. Lots of other smaller touches made me appreciate Transport Fever 2 a lot more than the first game. For example, in the Free Play mode you now get a mini-map of what your random map generation will look like, with the ability to tweak more until you're happy. They had a good foundation with Transport Fever and this second version builds upon it in a way that doesn't drastically change the experience but does make it feel a lot more worthwhile. It also looks awesome when you progress through it thanks to the improved graphics too. I just wish they did something with map borders, as they're just a hard edge. Sadly, the one big thing I was worried about simply hasn't been solved for the second game. The performance while you're placing tracks and buildings is not good, with my i7-5960X/2080Ti dropping down noticeably hard. This is not a Linux issue though, even on Windows 10 it suffers the same exact problems. Whatever calculations the game is doing when building, it eats away at it. Turning off the forced VSync can certainly help smoothen it out a little, but they chose to hide this setting so you can only do it in the configuration file found in your root Steam folder like: ~/.steam/root/userdata/*steamid*/1066780/local/settings.lua In the settings.lua file, change vsync to "false" and you should have a better time with it but the developer really needs to work on that performance. Thankfully, it's only an issue when building. Feature Highlight: Experience the greatest logistical challenges from 1850 to today across three unique story campaigns featuring voiceovers and cutscenes. Let your creativity run wild through giant sandbox maps in free play mode. Choose from over 200 realistically modeled vehicles from Europe, America and Asia, including trains, buses, streetcars, trucks, aircraft and ships, plus modular stations, airports and harbors. Track and manage your booming empire’s rise with intuitive construction tools and dynamic economy, transportation and city simulation systems. Choose from a diverse array of natural ecosystems, all rendered in exquisite detail. Create and share your own worlds, missions, landscapes, vehicles and more with the in-game map editor and extensive modding tools via Steam Workshop. I find that Transport Fever 2 is made for people who just love to build, then sit back and watch all the moving parts. That's what I end up doing anyway, zooming the camera around to just take it all in. Well, that and people with a keen mind for finances because you have to keep your business going. You start small, gradually expand as you ferry various supplies around and hopefully stay out of the red. As a sequel, it does the job nicely. They're offering a 10% discount until January 3rd. If you own the previous game, you also get an additional discount towards Transport Fever 2 to boost it up to 25% off. That's quite a big discount for a brand new game. Available on Humble Store, GOG and Steam.Article from GamingOnLinux.com

Heroku Review apps available for Treeherder

2019-12-11 20:54:27

In bug 1566207 I added support for Heroku Review Apps (link to official docs). This feature allows creating a full Treeherder deployment (backend, frontend and data ingestion pipeline) for a pull request. This gives Treeherder engineers the ability to have their own deployment without having to compete over the Treeherder prototype app (a shared deployment). This is important as the number of engineers and contributors increases. Once created you get a complete Heroku environment with add-ons and workers configured and the deployment for it. Looking back, there are few new features that came out of the work, however, Heroku Review apps are not used as widely as I would have hoped for. read more

Linux-driven RISC-V core to debut on an NXP i.MX SoC

2019-12-11 20:45:41

The OpenHW Group unveiled a Linux-driven “CORE-V Chassis” eval SoC due for tape-out in 2H 2020 based on an NXP i.MX SoC, but featuring its RISC-V-and PULP-based 64-bit, 1.5GHz CV64A CPU and 32-bit CV32E cores. Meanwhile, Think Silicon demonstrated a RISC-V-based NEOX|V GPU. A not-for-profit, open source RISC-V initiative called the OpenHW Group that launched in June has announced that it plans to tape out a Linux-friendly CORE-V Chassis evaluation SoC in the second half of 2020 built around its 64-bit CV64A CPU core and 32-bit CV32E coprocessor. The RISC-V based cores will be integrated into an undefined, NXP i.MX heterogeneous, multi-core SoC design. The SoC was announced at this week’s RISC-V Summit in San Jose, Calif., where Think Silicon also demo’d an early version of a RISC-V-based NEOX|V GPU (see farther below). The open source CV64A CPU core and 32-bit CV32E are based on RISC-V architecture PULP Platform cores developed by the University of ETH Zurich. The 64-bit CV64A core is based on ETH Zurich’s Ariane implementation of its RV64GC RISC-V core IP. RV64GC is also used by many other RISC-V projects, including SiFive’s U54. read more
