LXer: 3 open source Python GUI frameworks

Wednesday 30th of August 2017 11:49:47 PM
There comes a time in the journey of most any programmer when they are ready to branch out past the basic examples and start to build a graphical interface to their program.In Python, the steps to get started with GUI programming are not terribly complex, but they do require the user to begin making some choices. By its nature as a general purpose programming language with interpreters available across every common operating system, Python has to be fairly agnostic as to the choices it presents for creating graphical user interfaces.read more

LXer: How to create reproducible build environments with Rebuild

Wednesday 30th of August 2017 10:29:44 PM
Building modern software in a predictable and repeatable way isn't easy. The overwhelming number of software dependencies and the need to isolate conflicting components presents numerous challenges in managing build environments.Although there are many tools aimed at mitigating this challenge, there are two approaches most of them take: either they rely on package managers to preserve and replicate package sets, or they use virtual or physical machines with preconfigured environments.read more

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

    With Google Summer of Code 2017 now in the books, the final reports on the various projects carried out within the BeOS-inspired Haiku operating system are now available.

  • 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?

Baidu puts open source deep learning into smartphones

A year after it open sourced its PaddlePaddle deep learning suite, Baidu has dropped another piece of AI tech into the public domain – a project to put AI on smartphones. Mobile Deep Learning (MDL) landed at GitHub under the MIT license a day ago, along with the exhortation “Be all eagerness to see it”. MDL is a convolution-based neural network designed to fit on a mobile device. Baidu said it is suitable for applications such as recognising objects in an image using a smartphone's camera.

AMD and Linux Kernel

  • Ataribox runs Linux on AMD chip and will cost at least $250
    Atari released more details about its Ataribox game console today, disclosing for the first time that the machine will run Linux on an Advanced Micro Devices processor and cost $250 to $300. In an exclusive interview last week with GamesBeat, Ataribox creator and general manager Feargal Mac (short for Mac Conuladh) said Atari will begin a crowdfunding campaign on Indiegogo this fall and launch the Ataribox in the spring of 2018. The Ataribox will launch with a large back catalog of the publisher’s classic games. The idea is to create a box that makes people feel nostalgic about the past, but it’s also capable of running the independent games they want to play today, like Minecraft or Terraria.
  • Linux 4.14 + ROCm Might End Up Working Out For Kaveri & Carrizo APUs
    It looks like the upstream Linux 4.14 kernel may end up playing nicely with the ROCm OpenCL compute stack, if you are on a Kaveri or Carrizo system. While ROCm is promising as AMD's open-source compute stack complete with OpenCL 1.2+ support, its downside is that for now not all of the necessary changes to the Linux kernel drivers, LLVM Clang compiler infrastructure, and other components are yet living in their upstream repositories. So for now it can be a bit hairy to setup ROCm compute on your own system, especially if running a distribution without official ROCm packages. AMD developers are working to get all their changes upstreamed in each of the respective sources, but it's not something that will happen overnight and given the nature of Linux kernel development, etc, is something that will still take months longer to complete.
  • Latest Linux kernel release candidate was a sticky mess
    Linus Torvalds is not noted as having the most even of tempers, but after a weekend spent scuba diving a glitch in the latest Linux kernel release candidate saw the Linux overlord merely label the mess "nasty". The release cycle was following its usual cadence when Torvalds announced Linux 4.14 release candidate 2, just after 5:00PM on Sunday, September 24th.
  • Linus Torvalds Announces the Second Release Candidate of Linux Kernel 4.14 LTS
    Development of the Linux 4.14 kernel series continues with the second Release Candidate (RC) milestone, which Linus Torvalds himself announces this past weekend. The update brings more updated drivers and various improvements. Linus Torvalds kicked off the development of Linux kernel 4.14 last week when he announced the first Release Candidate, and now the second RC is available packed full of goodies. These include updated networking, GPU, and RDMA drivers, improvements to the x86, ARM, PowerPC, PA-RISC, MIPS, and s390 hardware architectures, various core networking, filesystem, and documentation changes.
