Phoronix: Power Use, RAM + Boot Times With Unity, Xfce, GNOME, LXDE, Budgie & KDE Plasma

Wednesday 30th of August 2017 08:59:12 PM
One of the first follow-on requests from this morning's Razer Blade Stealth Linux testing was for on top of all the other data-sets shared in that article to also look at the RAM usage, battery power draw, and boot times for the different desktop options on Ubuntu 17.04. As the request came in from a Phoronix Premium supporter, I jumped on that and here are some of those numbers.

TuxMachines: today's leftovers

Wednesday 30th of August 2017 08:31:56 PM
  • Re-encoding DebConf17 videos

    Feedback we received after DebConf17 was that the quality of the released videos was rather low. Since I'd been responsible for encoding the videos, I investigated that, and found that I had used the video bitrate defaults of ffmpeg, which are rather low. So, I read some more documentation, and came up with better settings for the encoding to be done properly.

  • Internationalization, part five: documentation and release!

    This concludes all the tasks outlined by my Outreachy project, but of course not my involvement to LTSP Manager. I’ll keep using it in my schools and be an active part of its ecosystem. Many thanks to Debian Outreachy and to my mentors for the opportunity to work on this excellent project!

    The developers of Bodhi Linux have released Bodhi 4.3.0. Based on Ubuntu 16.04 LTS, this release is powered by Linux kernel 4.11. Please note that this isn’t a feature release and the existing users don’t need to perform a re-installation. The new users can visit the project’s website and choose from 3 flavors.

  • Google’s ARCore brings augmented reality to millions of Android devices

    Google is taking a second swing at augmented reality with a new SDK called "ARCore." The SDK is available for download today (Google should have a blog post here) along with a set of ARCore demos. After experimenting with Project Tango, an AR initiative launched in 2014 that loaded a smartphone up with custom sensors, Google's AR reboot brings most of that functionality to regular old Android phones through the magic of software. If you're drawing mental comparisons to Apple's ARKit, you're on the right track.

    We're not just working off the blog post here, as I was lucky enough to have this project explained to me by some of the Googlers in charge of it. Let's start with the basics.

TuxMachines: Threadripper, Ryzen, and AMD

Wednesday 30th of August 2017 08:31:03 PM
  • LLVMpipe & OpenSWR OpenGL Riding Off Threadripper

    One of the unique test requests coming in as part of our Threadripper on Linux testing is to see how well the LLVMpipe and OpenSWR CPU-based OpenGL implementations within Mesa perform for this 16 core / 32 thread single-socket processor. Here are those results.

    A few days back I did a similar LLVMpipe/SWR comparison on a 80 thread Intel system so check out those numbers if you are unfamiliar with these CPU-based OpenGL drivers... This testing is done mostly for curiosity about the viability of LLVMpipe/SWR on CPUs with high core counts.

  • New Ryzen runs well under Linux

    After AMD confirmed the "performance marginality problem" for Ryzen Linux users, RMAs have been being issued and replacement Ryzen processors arriving for those affected. Now Phoronix has been able to confirm that the new Ryzen CPUs are now stable.

    For those who came in late, some Linux users reported a segmentation fault problem that would occur under very heavy workloads. Now the replacements have been shipped, Phoronix has been able to test the Ryzen Threadripper 1950X under the same heavy loads which caused it to go tits up.

TuxMachines: KDE: GSoC Projects and Belated Akademy 2017 Coverage

Wednesday 30th of August 2017 08:15:58 PM
  • GSoC - Third month analysis

    My aim was to work on note names and piano composition and those are the most basic activies kids need to learn. A child should learn note names first to have a good understanding of note position and naming convention. Then the activity piano composition should be played to have the knowledge of musical notation and musical staff, then comes the play piano activity which explains how the piano keyboard can play music as written on musical staff and then the rhythms are learnt on the basis of what they see and hear in play rhythm. In the last two weeks I worked on completing Note names which you can test in my branch note names.

  • GSoC Final report - Part 1: Okular

    This is the first post of a 3-part series where I will go into technical details of my summer of code project. I will give a high-level overview about the current state of my written code, show you what’s supposed to work and how you can try that; and what still needs to be done.

    Then I will write about some “Gotcha!” moments I have experienced in the past few months and what I could learn from them. Those aren’t in any way ordered and are there to explain why my project turned out like it did - and hopefully even help some future GSoC students along the way.

  • GSoC Final report - Part 2: Gwenview

    A first revision of my patch is up on phabricator, which works for raster graphics. Your holiday pictures should now open in all their details and no longer be a blurry mess!

  • GSoC Final report - Part 3: Summary

    I can’t believe the three months are already over, the time flies when you’re having fun.

    Unfortunately, I couldn’t tackle everything I had planned - the rendering in Okular and Gwenview was much complexer than I anticipated. Once again, it needs much more time to modify existing code than to write new one.

    Nevertheless, I enjoyed this challenge and hope the code for Okular will be merged in the next days and can therefore be in the next release - making HiDPI a more pleasant experience for the whole KDE community.

TuxMachines: Operating Systems Genode and Haiku

Wednesday 30th of August 2017 08:10:12 PM
  • Release notes for the Genode OS Framework 17.08

    The flagship feature of Genode 17.08 has been in the works for more than a year: The support for hardware-accelerated graphics on Intel Gen-8 GPUs. This is an especially challenging topic because it is riddled with terminology, involves highly complex software stacks, carries a twisted history with it, and remains to be a moving target. It took up a lot of patience to build up a profound understanding of the existing driver architectures and the mechanisms offered by modern graphics hardware. On the other hand, with the proliferation of hardware-based sandboxing features like virtual GPU memory and hardware contexts, we found that now is the perfect time for a clean-slate design of a microkernelized GPU driver. Section Hardware-accelerated graphics for Intel Gen-8 GPUs introduces this work, which includes our new GPU multiplexer as well as the integration with the client-side Mesa protocol stack.

  • Genode 17.08 Now Supports Broadwell Graphics, Xen DomU Support

    Version 17.08 of the Genode open-source operating system framework is now available with a variety of changes.

    Genode OS 17.09 now features support for Intel "Gen 8" Broadwell graphics thanks to its ported open-source Intel Linux driver code and also upgrading to Mesa 11.2.2. They have made other improvements too for their graphics driver stack in Genode, including an experimental GPU multiplexer.

  • BeOS-Inspired Haiku OS Had A Successful GSoC 2017: Swift, Btrfs, Preferences GUI

  • Building Healthy Open Source Communities: Please Join Me for a Very Special Event

    Community — what a profound difference it can make for projects, businesses and organizations of all types. I’ve spent my entire career helping organizations build communities, ranging from internal communities to developer communities, with a strong focus on open source communities. The goal in fostering a healthy community around open source is to engage consumers, customers, and others and encourage them to contribute. With these thoughts in mind, let us consider a few of the important first steps in setting a community strategy, and then I want to tell you about a very special community-focused event that is coming up.

  • "Qubes OS from the POV of a Debian developer" and "Qubes OS user meetup at Bornhack"

    I wrote the following while on my way home from Bornhack which was an awesome hacking camp on the Danish island of Bornholm, where about 200 people gathered for a week, with a nice beach in walking distance (and a not too cold Baltic Sea) and vegan and not so vegan grills, to give some hints why it was awesome. (Actually it was mostly awesome due to the people there, not the things, but anyway…)

Reddit: Running Linux on a Macbook

Wednesday 30th of August 2017 08:05:34 PM

Hello there! I think about buying an MacBook Pro 2017 without Touchbar. I use it at university for coding. I think about the MacBook because of its great built quality and good battery.

I would like to install Ubuntu (or some other Linux) alongside with MacOS. Has someone in here detailed experience with the stability and usability of Linux on this specific MacBook?

LinuxInsider: Too Few Candidates to Fill Growing Number of Open Source Jobs

Wednesday 30th of August 2017 07:12:39 PM
Open source hiring has been hampered by a lack of trained job-takers, according to The Linux Foundation, which released its sixth annual summary of career opportunities in open source last week. The report provides an overview of open source career trends, along with factors that motivate industry professionals, and methods employers use to attract and retain qualified talent. The 2017 report, developed in cooperation with Dice, follows the research approach taken in last year's report, with a focus on all aspects of open source software.

Reddit: Comparison of different DEs based on user scenarios

Wednesday 30th of August 2017 05:48:31 PM

Hello all, for a very long time I had a question: what DE to use with Linux. I've never liked Gnome, I lack some elegance in XFCE and something always went bad in KDE. So, I decided that I should make a comparison between these DE's based on use cases. I want to use Debian 9 as one of the most stable distros. Currently, I am a KDE4 Debian 8 user and I have absolutely no relevant experience with Debian 9 and modern versions of Gnome, xfce and kde.

For example:

Use case #1: open a default email program, add an account, receive letters, send a letter, find a letter by some phrase.

Use case #2: find a file in a default file manager .

Use case #3: open several tabs in chromium/firefox, decompose them and compose them back into one window.

Use case #4: archive and unarchive with a default archiver a complicated file-tree, for example, linux sources.

Use case #5: set up new values for hot-keys.

Use case #6: open a default packet manager and install several programs.

Use case #7: make some notes in note-taking application, find something in previous notes.

Use case #8: set up date and time, add an additional clock for another time zone.

Use case #9: open a default drawing program and draw a simple childish picture.

These use cases will be assessed on required time and provided comfort criteria by me (an experienced Linux user) and my wife (a windows user with no previous Linux experience).

As you can see, these use cases are far from ideal, so, if you have some suggestions on how to improve my methods of testing, or you have additional use cases, please, write them under this post.

Chromium and Firefox: New Features

  • Chromebook Owners Will Soon Be Able to Monitor CPU and RAM Usage in Real-Time
    Chromium evangelist François Beaufort announced today that Google's Chrome OS engineers have managed to implement a new feature that will let Chromebook owners monitor the CPU usage, RAM, and zRam statistics in real-time. The feature was implemented in the Chrome Canary experimental channel and can be easily enabled by opening the Google Chrome web browser and accessing the chrome://flags/#sys-internals flag. There you'll be able to monitor your Chromebook's hardware and see what's eating your memory or CPU during heavy workloads, all in real-time. "Chrome OS users can monitor in real-time their CPU usage, memory and zRam statistics thanks to the new internal page chrome://sys-internals in the latest Canary," said François Beaufort in a Google+ post. "For that, enable the experimental chrome://flags/#sys-internals flag, restart Chrome, and enjoy watching real-time resource consumption."
