  • DeviluitionX: Enjoying The 23 Year Old Diablo Game Atop An Open-Source Engine

    The latest open-source game engine project working to re-implement a legendary commercial game is DeviluitionX. This new effort is an open-source re-implementation of Blizzard's Diablo game from 1996 while now working on Linux and other operating systems nicely.

    The DeviluitionX effort has already reached "a fully playable state on Linux / macOS / Windows, with only minor issues remaining." DeviluitionX does require the game assets from the official Diablo release, which is now available easily from GOG.com following the recent Diablo release on that DRM-free platform.

  • Walmart Is Planning Its Own Gaming Streaming Service: Report

    Google recently entered the $140 billion gaming industry by launching Stadia, a cloud-gaming service. The company garnered a lot of attention from tech enthusiasts as it showcased the service that supports 4K resolutions and gaming at 60fps.

  • Exclusive: Walmart is Talking to Developers and Publishers About a Potential Streaming Service

    Google made headlines this week when it announced its arrival into the video game space with a new streaming venture called Stadia. But according to sources, another major corporation is investigating the video game streaming business too, and it's none other than Walmart.

    Multiple sources familiar with Walmart's plans, who wish to remain anonymous, confirmed to USG that the retail giant is exploring its own platform to enter in the now-competitive video game streaming race. No other details were revealed other than it will be a streaming service for video games, and that Walmart has been speaking with developers and publishers since earlier this year and throughout this year's Game Developers Conference.

  • Google Has Killed 147 Projects, Will Stadia Join Them?
  • In Deathbulge: Battle of the Bands, music is your weapon and it's coming to Linux

    One Kickstarter I completely missed is Deathbulge: Battle of the Bands, a musical themed quirky RPG where music is your weapon. The campaign is over and it managed to smash the funding goal, with Linux noted as a release platform.

    Based on the Deathbulge comic from Dan Martin (who is involved too of course in this), over two thousand backers pledged their support to give the developers just under sixty thousand dollars to bring the game to life. It smashed some stretch goals, including bringing in guest artists and having more character classes.

  • Baba Is You is an excellent rule-breaking puzzle game, some thoughts

    Baba Is You, a recent puzzle game release from Hempuli Oy offers a pretty different take on the genre and I have some thoughts. Note: My key was provided by the developer directly. Also, likely spoilers contained within.

    Baba is honestly like no other puzzle game I can think of, one where you are literally changing the rules of the game to progress through each level and it's a magical experience. Truthfully, I thought it would be quite a simple game considering the mechanics but I've been massively surprised overall.

  • Epic Games new 'Epic Online Services' will support Linux and it's free for developers to use

    Building upon the work they've done with Fortnite, it's going to offer support for: Parties, an in-game Overlay, Matchmaking, Player reports, Achievements, leaderboards, stats and so on. Don't get too excited though, as right now it's only offering Game analytics (telemetry about players) and a support ticket system with everything else "Coming soon".

  • We. The Revolution sounds pretty awesome and it's out now

    Set in the blood-soaked and paranoid world of the French Revolution, We. The Revolution from Polyslash is officially out with Linux support.

    As much as I wanted to have some thoughts on it, given how incredibly interesting it sounds, I can't. GOG's Linux team sent over a copy but I'm not quite sure what's going on with the GOG release at this point. It advertises Linux support yet it has no Linux download even though supposed to have one, so there's some kind of delay on GOG's side with it. Update: Now actually live on GOG too.

  • 2D indie platformer fighter 'Super Powered Battle Friends' looks interesting in the new trailer

    One thing we don't have enough of on Linux, is good platform fighting games and Super Powered Battle Friends is looking pretty good.

    Last time I wrote about it, there wasn't an official trailer to properly show it off.

  • Effective HMI interaction and safety attention monitoring using eye tracking technology: DeepGlance Quick

    Interacting effectively with increasingly widespread and advanced systems is one of the most important challenges of our time. Most modern HMIs are based on mouse, keyboard or touch screen and allow controlling even very complex devices in a simple and intuitive way. However, in certain contexts, the user may be unable to have direct contact with a device, in this case, we are talking about hands-free interactions and often voice commands are used to interact. But controlling a system by voice, however natural, is not effective for all types of operations and in all environments. In fact, every technology has its peculiarities, that’s why the HMI design and the UX are the subject of continuous research and aim to offer increasingly effective and natural interaction methods, also thanks to the combined use of more complementary technologies between them.

  • Seven ways to improve your team’s Python

    If you’re a manager, then you’re always trying to find ways that’ll help your team do more in less time. That’s why you use Python — because it makes your developers more productive. They can spend more time creating new features, and less time debugging or maintaining existing code. It’s no surprise that so many companies are moving to Python.

    After you’ve moved to Python, you can still make your team more effective. That is, your organization can become more productive, combining technology and culture to help your developers improve. In such a scenario, everyone wins: Your company becomes more efficient and effective, and your team members are more satisfied.

  • Rust All Hands 2019: Array iterators, Rayon, and more

    A few weeks ago, I had the pleasure of attending the second annual Rust All Hands meeting, hosted by Mozilla at their Berlin office. The attendees were a mix of volunteers and corporate employees covering the full range of Rust development, including the compiler, language, libraries, docs, tools, operations, and community. Although I’m sure there will be an official summary of the meeting (like last year’s), in this article, I’ll cover a few things I was directly involved in. First, I’ll look at a feature many developers have wanted for a long time…

  • GCC 9 libstdc++ Lands The C++17 Parallel Algorithms Implementation From Intel

    While the release of GCC 9 (v9.1) is just a few weeks ago, a late addition to this annual compiler collection update is its C++ standard library now having a C++17 parallel algorithms implementation thanks to Intel developers.

    Intel has been working on contributing their C++17 parallel algorithms library code to both GCC and also to the LLVM project. Intel has been working on this Parallel STL implementation the past few years with a focus on contributing the support to the libc++ and libstdc++ C++ standard libraries. The Parallel STL is a portable implementation of threaded/vectorized execution of standard C++ algorithms, which can equate to a performance win on today's multi-core systems.

How to save time with TiDB

Filed under
OSS

Last November, I wrote about key differences between MySQL and TiDB, an open source-compatible, cloud-based database engine, from the perspective of scaling both solutions in the cloud. In this follow-up article, I'll dive deeper into the ways TiDB streamlines and simplifies administration.

If you come from a MySQL background, you may be used to doing a lot of manual tasks that are either not required or much simpler with TiDB.

The inspiration for TiDB came from the founders managing sharded MySQL at scale at some of China's largest internet companies. Since requirements for operating a large system at scale are a key concern, I'll look at some typical MySQL database administrator (DBA) tasks and how they translate to TiDB.

  • Norwegian firm attack likely through Microsoft Active Directory: claim

    The Windows network at the Norwegian aluminium maker Norsk Hydro was probably infiltrated by attackers who planted the LockerGoga ransomware using something like scheduled tasks or services in Microsoft's Active Directory, a British security expert says.

  • Microsoft starts notifying Windows 7 users about end of support

    Microsoft’s end of support date means that Windows 7 users will no longer receive security updates, and the company wants consumers to upgrade to Windows 10 PCs instead. While the notification doesn’t mention Windows 10, Microsoft links to a new Windows 7 site that encourages consumers to upgrade their PCs.

  • Critical flaw lets [attackers] control lifesaving devices implanted inside patients

    The federal government on Thursday warned of a serious flaw in Medtronic cardio defibrillators that allows attackers to use radio communications to surreptitiously take full control of the lifesaving devices after they are implanted in a patient.

    Defibrillators are small, surgically implanted devices that deliver electrical shocks to treat potentially fatal irregular heart rhythms. In recent decades, doctors have increasingly used radios to monitor and adjust the devices once they're implanted rather than using older, costlier, and more invasive means. An array of implanted cardio defibrillators made by Medtronic rely on two types of radio-based consoles for initial setup, periodic maintenance, and regular monitoring. Doctors use the company's CareLink Programmer in clinics, while patients use the MyCareLink Monitor in homes to regularly ensure the defibrillators are working properly.

12 open source tools for natural language processing

Filed under
OSS

Natural language processing (NLP), the technology that powers all the chatbots, voice assistants, predictive text, and other speech/text applications that permeate our lives, has evolved significantly in the last few years. There are a wide variety of open source NLP tools out there, so I decided to survey the landscape to help you plan your next voice- or text-based application.

For this review, I focused on tools that use languages I'm familiar with, even though I'm not familiar with all the tools. (I didn't find a great selection of tools in the languages I'm not familiar with anyway.) That said, I excluded tools in three languages I am familiar with, for various reasons.

The most obvious language I didn't include might be R, but most of the libraries I found hadn't been updated in over a year. That doesn't always mean they aren't being maintained well, but I think they should be getting updates more often to compete with other tools in the same space. I also chose languages and tools that are most likely to be used in production scenarios (rather than academia and research), and I have mostly used R as a research and discovery tool.

Ever wished your Android smartphone or Raspberry Pi was a laptop? Well, with the NexDock 2 project, now live on Kickstarter, it can be!

Both the name and the conceit should be familiar to long-time gadget fans. The original NexDock was a 14.1-inch laptop shell with no computer inside. It successfully crowdfunded back in 2016.

The OG device made its way in to the hands of thousands of backers. While competent enough, some of-the-time reviews were tepid about the dock’s build quality.

After a brief stint fawning over Intel’s innovative (now scrapped) Compute Cards, the team behind the portable device is back with an updated, refined and hugely improved model.

Graphics/Benchmarks
  • libinput 1.12.902
    The second RC for libinput 1.13 is now available.
    
    This is the last RC, expect the final within the next few days unless
    someone finds a particulaly egregious bug.
    
    One user-visible change: multitap (doubletap or more) now resets the timer
    on release as well. This should improve tripletap detection as well as any
    tripletap-and-drag and similar gestures.
    
    valgrind is no longer a required dependency to build with tests. It was only
    used in a specific test run anyway (meson test --setup=valgrind) and not
    part of the regular build.
    
    As usual, the git shortlog is below.

    Peter Hutterer of Red Hat announced the release of libinput 1.13 Release Candidate 2 on Thursday as the newest test release for this input handling library used by both X.Org and Wayland Linux systems.

    Libinput 1.13 will be released in the days ahead as the latest six month update to this input library. But with the time that has passed, it's not all that exciting of a release as the Logitech high resolution scrolling support as well as Dell Totem input device support for the company's Canvas display was delayed to the next release cycle. But libinput 1.13 is bringing touch arbitration improvements for tablets, various new quirks, and other fixes and usability enhancements.

  • More keynotes hitting the stage at Red Hat Summit 2019

    Red Hat Summit 2019 is the industry’s premier enterprise open source technology conference. A place to come together to share ideas, collaborate with peers, learn from the work of others and celebrate advancements in open source. This year, we encourage you to think beyond your normal day-to-day, beyond the limitations and challenges you face, expand your possibilities to think about AND.

    No longer about having to choose, what if you could scale your technology AND culture to meet your needs to help you not just survive, but thrive in a changing business landscape? Think Linux AND containers. Think public AND private cloud. That’s what you’ll find at Red Hat Summit.

  • Red Hat Summit 2019 session highlights: Hybrid cloud infrastructure

    Cloud computing should not be a world that is dominated by public clouds or on-premises datacenters; instead, it should be a blend of technologies that create the concept of hybrid cloud. The Red Hat Global Customer Tech Outlook for 2019 further details this point, with only six percent of respondents planning a pure public cloud strategy, while 30 percent have a hybrid cloud strategy.

    So what exactly is the hybrid cloud mix? And how can you handle multiple public clouds plus on-premises resources? What about Kubernetes and containers? How is anyone REALLY doing this?

    At Red Hat Summit 2019, May 7-9 in Boston, Red Hat aims to address these questions and more around hybrid cloud infrastructure and strategies. From Kubernetes and Linux containers to hybrid cloud storage and functions-as-a-service (FaaS), presenters at Red Hat Summit will break these concepts down using real world examples to highlight the power, scale and innovation of hybrid cloud infrastructure in modern computing environments.

Gaming
  • Announcing CrossOver 18.5.0

    CrossOver 18.5 includes the FAudio library to provide superior audio support for games. FAudio is a reimplementation of XAudio2, a low-level audio library for Windows. This improvement broadens CrossOver’s game compatibility and resolves a wide variety of audio bugs on both macOS and Linux.

    CrossOver 18.5 resolves several Office 2010 bugs related to activation and licensing. The first involves a change which disrupted the activation status of Office 2010 bottles upgraded from CrossOver 17.x and earlier to CrossOver 18.x. Users who experienced persistent activation requests on earlier releases of CrossOver 18 should be able to successfully activate Office 2010 on CrossOver 18.5. We have also resolved a bug which caused Office 2010 to attempt and fail configuration on every launch for some users.

    On Linux, CrossOver 18.5 supports the very latest release of Office 365 and resolves a sign-in bug impacting Office 365 Home users.

    Finally, CrossOver 18.5 includes preliminary support for OneNote 2016 on Linux.

  • CrossOver 18.5 Released - Based On Wine 4.0 While Pulling In FAudio

  • Valve show off their new Steam Library design and a new Events page

    At GDC today, Valve did their presentation and they finally showed off the new design coming for the Library page and more.

    For those with a growing backlog of games, the Steam Library as it is right now is so basic it's just incredibly unhelpful. Going by what they've shown off, it's actually looking a serious amount better. Firstly, it has a home page for your Steam Library, to go over some recent games and recently updated titles, as well as show a slice of your friends list. That's a pretty handy feature, especially if you have a game you play regularly enough it will probably be quicker and easier to get going the next time.

  • You can now try XCOM 2 free until March 25th, also on a big sale

    Firaxis Games have put their strategy game XCOM 2 up to play for free between now and March 25th, so if you've been on the fence this is a great opportunity.

    It's quite easily my absolute favourite strategy game on Linux, much more interesting than the first of the newer XCOM games (although that's still damn fun too). It does have a few niggles and some performance issues here and there but that's not down to Feral Interactive's port as it's not much different on Windows.

  • Humble Store are giving away Tacoma during their Indie Mega Week sale
