  • All Zachtronics games are now available on itch.io

    Some good news for fans of high quality puzzle games, as Zachtronics entire library is now available to purchase on itch.io.

  • Valve has launched "Steam Labs", a place where Valve will show off new experiments

    Valve emailed in today to let us know about the new Steam Labs, a dedicated section on Steam for Valve to show off some experiments they're doing and for you to test and break them.

  • Valve Rolls Out Steam Labs

    Steam Labs was announced today with three initial experiments: Micro Trailers, The Interactive Recommender, and The Automated Show. Micro Trailers are six-second game trailers, The Interactive Recommender uses machine learning to show game titles you might like, and The Automated Show is a showpiece for secondary displays for highlighting different games.

  • Network transparency with Wayland

    I've managed to get hardware video encoding and decoding using VAAPI working with waypipe, although of course the hardware codecs are less flexible and introduce additional restrictions on the image formats and dimensions. For example, buffers currently need to have an XRGB8888 pixel format (or a standard permutation thereof), as the Intel/AMD VAAPI implementations otherwise do not appear to support hardware conversions from the RGB color space to the YUV color space used by video formats, and in the other direction. It's also best if the buffers have 64-byte aligned strides, and 16-pixel aligned widths and heights. The result of this can run significantly faster than encoding with libx264, although to maintain the same level of visual quality the bitrate must be increased.

    For games, using video compression with waypipe is probably worth the tradeoffs now. In some instances, it can even be faster. A 1024 by 768 SuperTuxKart window during a race, running with linear-format DMABUFs, losslessly replicated without compression via ssh on localhost, requires about 130MB/s of bandwidth and runs at about 40 FPS. (Using LZ4 or Zstd for compression would reduce bandwidth, but on localhost or a very fast network would take more time than would be saved by the bandwidth reduction.)

  • Ubuntu LTS releases (and so derivatives too) to get updated NVIDIA drivers without PPAs

    Good news everyone! Canonical will now be offering NVIDIA users up to date graphics drivers without the need to resort to a PPA or anything else.

    Since this will be for the Ubuntu LTS releases, this means other Linux distributions based on Ubuntu like Linux Mint, elementary OS, Zorin OS and probably many others will also get these updated NVIDIA drivers too—hooray!

    This is really great, as PPAs are not exactly user friendly and sometimes they don't get the testing they truly need when serving so many people. Having the Ubuntu team push out NVIDIA driver updates via an SRU (Stable Release Update), which is the same procedure they use to get you newer Firefox version, is a good way to do it.

Ubuntu Now Offers Latest Nvidia Graphics Drivers to LTS Users

  • Ubuntu Now Offers the Latest Nvidia Graphics Drivers to LTS Users

    Until now, anyone that has wanted to install Nvidia binary driver updates on Ubuntu 18.04 LTS has needed to make use of a separate PPA, futz around with random packages distributed online, or install the driver manually, by hand, the old-fashioned way.

    But not any more.

    Word on the street is that Ubuntu 18.04 LTS users can now install the latest releases of the proprietary Nvidia driver through the regular Ubuntu updates channel.

    The magic is made possible by the SRU (Stable Release Update) initiative. It’s this endeavour that keeps other apps, like Mozilla Firefox and Chromium, up to date on long-term support releases.

Steam Labs lets you peek into Valve’s experimental projects

  • Steam Labs lets you peek into Valve’s experimental projects

    Like most companies, much of what Valve (the company behind the hugely popular Steam game store) tinkers with behind the scenes never sees the light of day. Concepts are born, torn apart and rebuilt, and sometimes tossed away without anyone outside the company ever seeing a hint of it.

    Seems Valve is trying to change that, giving users an opportunity to provide feedback on potential new features before they’re fully baked. The company has just debuted a new project it calls “Steam Labs,” which will give super-early adopters an early peek at concepts that may or may not eventually make it into Valve’s Steam game store.

Ubuntu Will Make it Easier to Install Nvidia Drivers

  • Ubuntu Will Make it Easier to Install Nvidia Drivers

    It's about to get easier for Ubuntu LTS users to stay up-to-date with Nvidia's stable graphics drivers. The Linux Experiment said via YouTube yesterday that Ubuntu plans to make these drivers part of its Stable Release Updates (SRU) program, which means users won't have to rely on fiddly workarounds to install the latest drivers themselves.
    Ubuntu confirmed The Linux Experiment's report on Twitter. (The company said it didn't make an official announcement because it "decided it better to share an awesome video from a member of the wider community.") It also said the change is "coming in an update, to your computer... [s]oon!" in response to another user.
    Ubuntu LTS typically doesn't offer recent updates to apps, drivers and other software. The operating system is more focused on making sure everything remains as stable as possible than on providing access to the latest-and-greatest features. SRU offers a compromise by making it easy to install new versions of popular apps.

Excellent! Ubuntu LTS Users Will Now Get the Latest Driver

  • Excellent! Ubuntu LTS Users Will Now Get the Latest Nvidia Driver Updates [No PPA Needed Anymore]

    You might be aware of the troubles to install the latest and greatest Nvidia binary driver updates on Ubuntu.

    By default, Ubuntu provides the open source Nvidia Nouveau drivers that some time result in Ubuntu being stuck at boot screen.

    You can also install the proprietary Nvidia driver in Ubuntu easily. The problem is that the Nvidia drivers in the default Ubuntu repositories are not the latest one. To solve this problem, Ubuntu introduced a dedicated PPA a few years back.

Ubuntu LTS Linux Distributions Will Now Get The Latest Nvidia

  • Ubuntu LTS Linux Distributions Will Now Get The Latest Nvidia Drivers Installed Automatically

    The Linux Experiment dropped the news on YouTube, reporting that Ubuntu LTS installs will now automatically include the latest proprietary Nvidia graphics driver in its standard system updates. The newest stable Nvidia driver, version 430, is already in the bionic-proposed repository for testing and should land on your Ubuntu 18.04 system soon.

    [...]

    The only oddity surrounding this announcement? Well, it's a very impactful change but was seeded through a community YouTuber (albeit an excellent one), and not via a Canonical-penned blog or press release. The company responded to this on Twitter, saying "We decided it better to share an awesome video from a member of the wider community. Ubuntu is all about community, after all."

Ubuntu To Provide NVIDIA Drivers Updates To Ubuntu LTS Users

  • Ubuntu To Provide NVIDIA Drivers Updates To Ubuntu LTS Users

    Ubuntu has been a good choice to switch to Linux from other operating systems. The only thing that has stopped people is the hardware updates. Though there were NVIDIA drivers updates available but through third-party PPAs.

    But no more installation of third-party PPAs in Ubuntu 18.04 LTS. Ubuntu is now going to provide the latest NVIDIA drivers updates to its long term release users starting from its latest LTS release Ubuntu 18.04.

    The big news was announced through Ubuntu’s twitter account posting a Youtube video describing how Ubuntu is already testing the feature and will release to the public very soon.

    Let me tell you, updating Nvidia drivers were not difficult but required the installation of third-party PPAs or run several scripts to update NVIDIA drivers.

    As explained in the video, Ubuntu will now provide the latest proprietary drivers updates from its repositories in Ubuntu 18.04 LTS and also Ubuntu 16.04 in the near future.

  • First‑of‑its‑kind spyware sneaks into Google Play
  • Open-source spyware bypasses Google Play defenses — twice

    Radio Balouch — the app in question — is a legitimate radio application serving Balouchi music enthusiasts, except that it also included AhMyth, a remote access espionage tool that has been available on GitHub as an open-source project since late 2017. Lukas Stefanko, ESET researcher who uncovered the campaign, said the app was uploaded twice on Google Play — once on July 2 and a second time on July 13 — only to be swiftly removed by Google within 24 hours upon being alerted by the security team. It continues to be available on third-party app stores. While the service’s dedicated website “radiobalouch.com” is no longer accessible, the attackers also seem to have promoted the app on Instagram and YouTube. The app, in total, attracted over 100 installs.

  • 61 impacted versions of Apache Struts left off security advisories

    Security researchers have reviewed security advisories for Apache Struts and found that two dozen of them inaccurately listed affected versions for the open-source development framework. The advisories have since been updated to reflect vulnerabilities in an additional 61 unique versions of Struts that were affected by at least one previously disclosed vulnerability but left off the security advisories for those vulnerabilities.

Linux Foundation: Automotive Grade Linux Announcement and Calling Surveillance Operations "Confidential Computing"

  • Automotive Grade Linux Announces New Instrument Cluster Expert Group and UCB 8.0 Code Release

    Automotive Grade Linux (AGL), an open source project developing a shared software platform for in-vehicle technology, today announced a new working group focused on Instrument Cluster solutions, as well as the latest code release of the AGL platform, the UCB 8.0. The AGL Instrument Cluster Expert Group (EG) is working to reduce the footprint of AGL and optimize the platform for use in lower performance processors and low-cost vehicles that do not require an entire infotainment software stack. Formed earlier this year, the group plans to release design specifications later this year with an initial code release in early 2020. “AGL is now supported by nine major automotive manufacturers, including the top three producers by worldwide volume, and is currently being used in production for a range of economy and luxury vehicles” said Dan Cauchy, Executive Director of Automotive Grade Linux at the Linux Foundation. “The new Instrument Cluster Expert Group, supported by several of these automakers, will expand the use cases for AGL by enabling the UCB platform to support solutions for lower-cost vehicles, including motorcycles.”

  • Shhh! Microsoft, Intel, Google and more sign up to the Confidential Computing Consortium

    The Linux Foundation has signed up the likes of Microsoft and Google for its Confidential Computing Consortium, a group with the laudable goal of securing sensitive data. The group – which also includes Alibaba, Arm, Baidu, IBM, Intel, Red Hat, Swisscom and Tencent – will be working on open-source technologies and standards to speed the adoption of confidential computing. The theory goes that while approaches to encrypting data at rest and in transit have supposedly been dealt with, assuming one ignores the depressingly relentless splurts of user information from careless vendors, keeping it safe while in use is quite a bit more challenging. Particularly as workloads spread to the cloud and IoT devices.

  • Tech giants come together to form cloud security watchdog

    Some of the world’s biggest technology companies are joining forces to improve the security of files in the cloud. This includes Google, IBM, Microsoft, Intel, and many others. The news first popped up on the Linux Foundation, where it was said that the Confidential Computing Consortium will work to bring industry standards and identify the proper tools to encrypt data used by apps, devices and online services. At the moment, cloud security solutions focus to protect data that’s either resting, or is in transit. However, when the data is being used is “the third and possibly most challenging step to providing a fully encrypted lifecycle for sensitive data.”

  • Tech firms join forces to boost cloud security

    Founding members of the group – which unites hardware suppliers, cloud providers, developers, open source experts and academics – include Alibaba, Arm, Baidu, Google Cloud, IBM, Intel, Microsoft, Red Hat, Swisscom and Tencent. [...] “The earliest work on technologies that have the ability to transform an industry is often done in collaboration across the industry and with open source technologies,” said Jim Zemlin, executive director at the Linux Foundation. “The Confidential Computing Consortium is a leading indicator of what is to come for security in computing and will help define and build open technologies to support this trust infrastructure for data in use.”

  • Google, Intel and Microsoft form data protection consortium
  • Intel Editorial: Intel Joins Industry Consortium to Accelerate Confidential Computing

    Leaders in information and infrastructure security are well versed in protecting data at-rest or in-flight through a variety of methods. However, data being actively processed in memory is another matter. Whether running on your own servers on-prem, in an edge deployment, or in the heart of a cloud service provider’s data center, this “in-use” data is almost always unencrypted and potentially vulnerable.

  • Confidential Computing: How Big Tech Companies Are Coming Together To Secure Data At All Levels

    Data today moves constantly from on-premises to public cloud and the edge, which is why it is quite challenging to protect. While there are standards available that aim to protect data when it is in rest and transit, standards related to protecting it when in use do not exist. Protecting data while in use is called confidential computing, which the Confidential Computing Consortium is aiming to create across the industry. The Confidential Computing Consortium, created under the Linux Foundation, will work to build up guidelines, systems and tools to ensure data is encrypted when it’s being used by applications, devices and online services. The consortium says that encrypting data when in use is “the third and possibly most challenging step to providing a fully encrypted lifecycle for sensitive data.” Members focused on the undertaking are Alibaba, ARM, Baidu, Google Cloud, IBM, Intel, Microsoft, Red Hat, Swisscom and Tencent.

  • IT giants join forces for full-system data security

    Apple is conspiciously missing from the consortium, despite using both Intel hardware and inhouse designed ARM-based processors. Of the first set of commitments, Intel will release its Software Guard Extensions (SGX) software development kit as open source through the CCC.

  • Google, Intel, and Microsoft partner to improve cloud security

    Some of the biggest names in tech have banded together in an effort to promote industry-wide security standards for protecting data in use.

  • Alibaba, Baidu, Google, Microsoft, Others Back Confidential Computing Consortium

    The Confidential Computing Consortium aims to help define and accelerate open-source technology that keeps data in use secure. Data typically gets encrypted by service providers, but not when it’s in use. This consortium will focus on encrypting and processing the data “in memory” to reduce the exposure of the data to the rest of the system. It aims to provide greater control and transparency for users.

  • Microsoft, Intel and others are doubling down on open source Linux security

    In other words, the operating system could be compromised by some kind of malware, but the data being used in a program would still be encrypted, and therefore safe from an attacker.

  • Microsoft, Intel, and Red Hat Back Confidential Computing

    The Linux Foundation’s latest project tackles confidential computing with a group of companies that reads like a who’s who of cloud providers, chipmakers, telecom operators, and other tech giants. Today at the Open Source Summit the Linux Foundation said it will form a new group called the Confidential Computing Consortium. Alibaba, Arm, Baidu, Google Cloud, IBM, Intel, Microsoft, Red Hat, Swisscom, and Tencent all committed to work on the project, which aims to accelerate the adoption of confidential computing.
