Benchmarks Of Ubuntu 17.04 Beta vs. Antergos, Clear Linux, openSUSE Tumbleweed

Saturday 25th of February 2017 08:30:00 PM
For those curious how Ubuntu 17.04 is shaping up, considering this week was the "beta" release for participating flavors, I decided to take a fresh Ubuntu 17.04 x86_64 daily ISO and see how its performance compares to Ubuntu 17.10, Clear Linux 13600, Antergos 17.2, and openSUSE Tumbleweed.

A Soft Implementation Of ARB_gpu_shader_fp64 Is Slowly Being Tackled For Mesa

Saturday 25th of February 2017 06:08:38 PM
Last year there was a Google Summer of Code student working on a library to implement double-precision operations (FP64) in pure GLSL 1.30 as a benefit to older GPUs not having native FP64 capabilities. While that work didn't materialize as a solution in 2017 for those wanting "soft" ARB_gpu_shader_fp64 for being able to potentially expose OpenGL 4.0 on more R600g era GPUs, the work is ongoing...

UKSM Is Still Around For Data Deduplication Of The Linux Kernel

Saturday 25th of February 2017 03:50:00 PM

Experimental Patches Revised For AMDGPU HDMI Stereo 3D, DAL/DC Now Supported

Saturday 25th of February 2017 12:43:45 PM
Last month an independent contributor to the AMD Linux graphics stack posted AMDGPU patches for HDMI Stereo 3D support within this open-source Radeon DRM driver. Those patches were rather dismissed in part because they didn't implement the support along the new DAL/DC display code-paths, but that has now changed...

RADV Vulkan Performance Appears To Improve With Linux 4.11

Friday 24th of February 2017 08:24:17 PM
A few days ago I posted some results of surprise performance improvements for a Radeon RX 470 when testing the DRM-Next code queued for Linux 4.11. I've now tested that kernel on more systems and can confirm at least benefits more widespread for RADV's Vulkan performance.

Fresh RadeonSI Mesa Git Gaming Benchmarks On 7 Linux Desktops

Friday 24th of February 2017 05:35:00 PM
When posting last week our Windows 10 vs. Ubuntu Radeon benchmarks and Windows vs. Linux NVIDIA Pascal benchmarks and then the Windows vs. Linux relative performance analysis, as usual, it didn't take long for some to argue that the Linux gaming performance is actually faster but "Unity 7 is slower" and the similar FUD that is usually waged whenever looking at cross-platform performance.

Fuzzing Mesa Drivers Begin To Uncover Bugs

Friday 24th of February 2017 04:18:47 PM
Last December we wrote about work being done on fuzzing OpenGL shaders leading to wild differences with the work being done at the Imperial College London. While they were testing other drivers on different operating systems, they have now fired up tests of Mesa...

Leftovers: OSS

  • Diving into Drupal: Princeton’s Multi-site Migration Success with Open-source
    Princeton University’s web team had a complex and overwhelming digital ecosystem comprised of many different websites, created from pre-built templates and hosted exclusively on internal servers. Fast forward six years: Princeton continues to manage a their multisite and flagship endeavors on the open-source Drupal platform, and have seen some great results since their migration back in 2011. However, this success did not come overnight. Organizational buy-in, multi-site migration and authentication were a few of the many challenges Princeton ran into when making the decision to move to the cloud.
  • GitHub Invites Developers to Contribute to the Open Source Guides
    GitHub has recently launched its Open Source Guides, a collection of resources addressing the most common scenarios and best practices for both contributors and maintainers of open source projects. The guides themselves are open source and GitHub is actively inviting developers to participate and share their stories.
  • Top open source projects
    TechRadar recently posted an article about "The best open source software 2017" where they list a few of their favorite open source software projects. It's really hard for an open source software project to become popular if it has poor usability—so I thought I'd add a few quick comments of my own about each.
  • Dropbox releases open-source Slack bot
    Dropbox is looking to tackle unauthorized access and other security incidents in the workplace with a chatbot. Called Securitybot, it that can automatically grab alerts from security monitoring tools and verify incidents with other employers. The company says that through the use of the chatbot, which is open source, it will no longer be necessary to manually reach out to employees to verify access, every time someone enters a sensitive part of the system. The bot is built primarily for Slack, but it is designed to be transferable to other platforms as well.
  • Dropbox’s tool shows how chatbots could be future of cybersecurity
    Disillusion with chatbots has set in across the tech industry and yet Dropbox’s deep thinkers believe they have spotted the technology’s hidden talent: cybersecurity.

Desktop GNU/Linux

  • Entroware have unleashed the 'Aether' laptop for Linux enthusiasts featuring Intel's 7th generation CPUs
  • New Entroware Aether Laptop Pairs Intel Kaby Lake with Ubuntu
    The new Entroware Aether is the latest Linux powered laptop from British company Entroware, and is powered by the latest Intel Kaby Lake processors.
  • Freedom From Microsoft v1.01
    But we can be Free from Microsoft! As we saw above, there is a powerful – and now popular movement afoot to make alternative software available. The Free Software Foundation, and the GNU Project, both founded by Richard Stallman, provide Free software to users with licenses that guarantee users rights: the rights to view, modify, and distribute the software source code. With GNU-licensed software, such as Linux, the user is in complete control over the software they employ. And as people contribute to modify Free Software source code, and are required to share those modifications again, the aggregate creative acts give rise to the availability of many more, much more useful results. Value is created beyond what anyone thought possible, and our freedom multiplies.
  • Review of the week 2017/08
    This week we had to cancel a couple snapshots, as a regression in grub was detected, that caused issues on chain-loading bootloaders. But thanks to our genius maintainers, the issue could be found, fixed and integrated into Tumbleweed (and this despite being busy with hackweek! A great THANK YOU!). Despite those canceled snapshots, this review will still span 4 revisions: 0216, 0218, 0219 and 0224. And believe me, there have been quite some things coming your way.

Security Leftovers

  • [Older] The Secure Linux OS - Tails
    Some people worry a lot about security issues. Anyone can worry about their personal information, such as credit card numbers, on the Internet. They can also be concerned with someone monitoring their activity on the Internet, such as the websites they visit. To help ease these frustrations about the Internet anyone can use the Internet without having to “look over their shoulder”.
  • Password management made easy as news of CloudFlare leak surfaces
    In the last 24 hours, news broke that a serious Cloudflare bug has been causing sensitive data leaks since September, exposing 5.5 million users across thousands of websites. In addition to login data cached by Google and other search engines, it is possible that some iOS applications have been affected as well. With the scale of this leak, the best course of action is to update every password for every site you have an account for. If there was ever a good time to modernize your password practices, this is it. As consumers and denizens of the Internet, we have a responsibility to be aware of the risks we face and make an attempt to mitigate that risk by taking best-effort precautions. Poor password and authentication hygiene leaves a user open to risks such as credit card fraud and identity theft, just like forgetting to brush your teeth regularly can lead to cavities and gum disease. This leaves us with the question of what good password and authentication hygiene looks like. If we stick with the (admittedly poorly chosen) dentistry analogy, then there are five easily identifiable aspects of good hygiene.
  • Security: You might want to change passwords on sites that use Cloudflare
  • Smoothwall Express
    The award-winning Smoothwall Express open-source firewall—designed specifically to be installed and administered by non-experts—continues its forward development march with a new 3.1 release.

Leftovers: Ubuntu and Derivatives

  • 'Big Bang Theory's' Stuart wears Ubuntu T-shirt
    Am I the only person to notice that comic book shop-owning Stuart (Kevin Sussman) on the "The Big Bang Theory" is wearing an Ubuntu T-shirt on the episode airing Thursday, Feb. 23, 2017? (It's Season 10, Episode 17, if that information helps you.) The T-shirt appearance isn't as overt as Sheldon's mention of the Ubuntu Linux operating system way back in Season 3 (Episode 22, according to one YouTube video title), but it's an unusual return for Ubuntu to the world of "Big Bang."
  • Unity Explained: A Look at Ubuntu’s Default Desktop Environment
    Ubuntu is the most well-known version of Linux around. It’s how millions of people have discovered Linux for the first time, and continues to draw new users into the world of open source operating systems. So the interface Ubuntu uses is one many people are going to see. In this area, Ubuntu is unique. Even as a new user, rarely will you confuse the default Ubuntu desktop for something else. That’s because Ubuntu has its own interface that you can — but probably won’t — find anywhere else. It’s called Unity.
  • A Look at Ubuntu MATE 16.04.2 LTS for Raspberry Pi
    Installing Ubuntu MATE onto my Raspberry Pi 3 was straight forward. You can easily use Etcher to write the image to a microSD card, the partition is automatically resized to fill your microSD card when the pi is powered up for the first time, and then you are sent through a typical guided installer. Installation takes several minutes and finally the system reboots and you arrive at the desktop. A Welcome app provides some good information on Ubuntu MATE, including a section specific for the Raspberry Pi. The Welcome app explains that the while the system is based on Ubuntu MATE and uses Ubuntu armhf base, it is in fact using the same kernel as Raspian. It also turns out that a whole set of Raspian software has been ported over such as raspi-config, rpi.gpio, sonic-pi, python-sent-hat, omxplayer, etc. I got in a very simple couple of tests that showed that GPIO control worked.
