TuxMachines: CPUFreq vs. P-State CPU Scaling Governor Tests On Various Vulkan/OpenGL Games

Tuesday 4th of April 2017 01:57:43 PM

With the recent release of some new Linux games like the Serious Sam 2017 update and Max Max, also with featuring Vulkan renderers, here are some fresh Intel P-State vs. ACPI CPUFreq frequency scaling driver and governor comparisons with a variety of Linux games.

Particularly on the P-State side, our CPU scaling driver tests over the years have showed the potential for big swings in performance depending upon the governor/driver, but in other games there are minimal differences. The Intel CPU generation can also play a role with sometimes the newer Intel hardware having a tougher time performing well with the Intel P-State powersave mode that's commonly the default on many Linux distributions.

Reddit: Is it possible to run a script at startup to open an application in fullscreen and require the sudo password to change screens?

Tuesday 4th of April 2017 01:45:01 PM

I am building an Augmented Reality Sandbox for the Science Department on my college campus. What I am hoping to do for ease of access (and to impress my supervisors) is to open the AR application, and lock the session down to only run this app and require the sudo password to change screens?

    ONAP is a collaborative open source project hosted by The Linux Foundation and formed in February through the combination of AT&T’s ECOMP and The Linux Foundation’s Open Orchestrator Project (OPEN-O). The two projects joined under ONAP to develop an open software platform for real-time, policy-driven software automation of virtual network functions. ONAP enables software, network and cloud provider companies as well as open source community developers to collaborate in an open ecosystem, encouraging rapid creation of new services and innovation.

  • Linux 4.10.8, 4.9.20 LTS and 4.4.59 LTS Kernels Are Out to Address Various Bugs

    At the end of March, Greg Kroah-Hartman released three new maintenance updates for the long-term supported Linux 4.9 and 4.4 kernel series, as well as the latest stable Linux 4.10 kernel branch.

    Linux 4.10.8, 4.9.20 LTS and 4.4.59 LTS kernels are out, and they come only one day after their previous maintenance updates, which means that all of them are small patches addressing a few bugs that needed to be fixed urgently. Of course, users are urged to update their systems to these new versions as soon as possible.

  • Google Launches a New Issue Tracker, Used for Android and the GCP

    Exactly one month ago, Google announced they had just launched a new Issue Tracker project for their Google Cloud Platform products. Until now, if you wanted to submit a bug about a Google product then you were pointed at a code.google.com URL. For Android, this would be the AOSP Issue Tracker and it would be the Chromium Issue Tracker for Chrome. This worked fine for a while, but even this issue tracker had some bugs and it just looked like a dated system.

  • Sorry Windows, Android is now the most popular end-user operating system

    For decades, the answer to the question "What's the most popular operating system?" was Windows. You may not have liked it, but macOS, OS/2, Linux, you name it, couldn't knock it off its pedestal. But, then along came smartphones and tablets, and PCs started their long sales decline. In March 2017, by web-analytics company StatCounter's reckoning, Android became more popular than Windows.

  • Android is more popular than Windows... for getting online [iophk: "at those figures the monopoly rents will become unobtainable and without additional income, such as stock trading, the bubble will pop"]

    Usage figures published by StatCounter show that Android accounted for 37.93 percent of the worldwide OS Internet usage share in March. Windows is not far behind at 37.91 percent, but Android taking the lead is being described as a "milestone in technology history."

    [...]

    Windows is starting to lose out overall, although it still accounts for 84 percent of the worldwide desktop operating system market.

  • Android overtakes Windows for first time
  • Android beats Windows as most popular OS for interwebz – by 0.02%

    The Raspberry Pi is very popular with DIY enthusiasts because of the seemingly endless possibilities of how you can design devices with it.

  • Light a fire under Cassandra with Apache Ignite
    Apache Cassandra is a popular database for several reasons. The open source, distributed, NoSQL database has no single point of failure, so it’s well suited for high-availability applications. It supports multi-datacenter replication, allowing organizations to achieve greater resiliency by, for example, storing data across multiple Amazon Web Services availability zones. It also offers massive and linear scalability, so any number of nodes can easily be added to any Cassandra cluster in any datacenter. For these reasons, companies such as Netflix, eBay, Expedia, and several others have been using Cassandra for key parts of their businesses for many years.
  • Proprietary Election Systems: Summarily Disqualified
    Hello Open Source Software Community & U.S. Voters, I and the California Association of Voting Officials, represent a group of renowned computer scientists that have pioneered open source election systems, including, "one4all," New Hampshire’s Open Source Accessible Voting System (see attached). Today government organizations like NASA, the Department of Defense, and the U.S. Air Force rely on open source software for mission critical operations. I and CAVO believe voting and elections are indeed mission-critical to protect democracy and fulfill the promise of the United States of America as a representative republic. Since 2004, the open source community has advocated for transparent and secure—publicly owned—election systems to replace the insecure, proprietary systems most often deployed within communities. Open source options for elections systems can reduce the costs to taxpayers by as much as 50% compared to traditional proprietary options, which also eliminates vendor lock-in, or the inability of an elections office to migrate away from a solution as costs rise or quality decreases.

  • Creative Commons Is Resurrecting Palmyra
    Creative Commons launched its 2017 Global Summit today with a rather moving surprise: a seven-foot-tall 3D printed replica of the Tetrapylon from Palmyra, Syria. For those who don't know the tragic situation, Palmyra is one of the most historic cities in the world — but it is being steadily destroyed by ISIS, robbing the world of countless irreplaceable artifacts and murdering those who have tried to protect them (the folks at Extra History have a pair of good summary videos discussing the history and the current situation in the city). Among ISIS's human targets was Bassel Khartabil, who launched Syria's CC community several years ago and began a project to take 3D scans of the city, which CC has been gathering and releasing under a CC0 Public Domain license. He was captured and imprisoned, and for the past five years his whereabouts and status have been unknown. As the #FreeBassel campaign continues, Creative Commons is now working to bring his invaluable scans to life in the form of 3D-printed replicas, starting with today's unveiling of the Tetrapylon — which was destroyed in January along with part of a Roman theatre after ISIS captured the city for a second time.
