12 hours 46 min ago
This last week marked two years since the debut of Vulkan 1.0, you can see our our original launch article. My overworked memory missed realizing it by a few days, but it's been a pretty miraculous two years for this high-performance graphics and compute API...

GCC 8 Will Let You -march=native Correctly On ARM/AArch64

Saturday 24th of February 2018 05:12:11 AM
Linux developers and enthusiasts on x86_64 have long enjoyed the ability to use the -march=native option for having the GCC compiler attempt to auto-detect the CPU and set the appropriate microarchitecture flags. That support is finally being offered up for ARM with GCC 8...

SDL Now Disables Mir By Default In Favor Of Wayland Compatibility

Friday 23rd of February 2018 07:15:57 PM
With Mir focusing on Wayland compatibility now, toolkits and other software making direct use of Mir's APIs can begin making use of any existing Wayland back-end instead. GTK4 drops the Mir back-end since the same can be achieved with the Wayland compatibility and now SDL is now making a similar move...

Pengutronix Gets Open-Source 3D Working On MX8M/GC7000 Hardware

Friday 23rd of February 2018 06:04:47 PM
We've known that Pengutronix developers had been working on i.MX8M / GC7000 graphics support within their Etnaviv open-source driver stack from initial patches posted in January. Those patches back at the start of the year were for the DRM kernel driver, but it turns out they have already got basic 3D acceleration working...

Radeon Linux OpenGL Driver Continues Giving Its Best Against Windows 10

Friday 23rd of February 2018 03:00:00 PM
With having around a Windows 10 installation this week for the latest Windows 10 WSL vs. Linux benchmarking, I also carried out some fresh benchmarks of the Radeon gaming performance between Windows 10 and Ubuntu Linux using the very latest drivers on each platform. This time around a Radeon RX 580 and RX Vega 64 were used for this benchmarking.

Another Potential Performance Optimization For KPTI Meltdown Mitigation

Friday 23rd of February 2018 08:41:23 AM
Now that the dust is beginning to settle around the Meltdown and Spectre mitigation techniques on the major operating systems, in the weeks and months ahead we are likely to see more performance optimizations come to help offset the performance penalties incurred by mitigations like kernel page table isolation (KPTI) and Retpolines. This week a new patch series was published that may help with KPTI performance...

  • SUNY math professor makes the case for free and open educational resources
    The open educational resources (OER) movement has been gaining momentum over the past few years, as educators—from kindergarten classes to graduate schools—turn to free and open source educational content to counter the high cost of textbooks. Over the past year, the pace has accelerated. In 2017, OERs were a featured topic at the high-profile SXSW EDU Conference and Festival. Also last year, New York State generated a lot of excitement when it made an $8 million investment in developing OERs, with the goal of lowering the costs of college education in the state. David Usinski, a math and computer science professor and assistant chair of developmental education at the State University of New York's Erie Community College, is an advocate of OER content in the classroom. Before he joined SUNY Erie's staff in 2007, he spent a few years working for the Erie County public school system as a technology staff developer, training teachers how to infuse technology into the classroom.

Mozilla: Wireless Innovation for a Networked Society, New AirMozilla Audience Demo, Firefox Telemetry

  • Net Neutrality, NSF and Mozilla's WINS Challenge Winners, openSUSE Updates and More
    The National Science Foundation and Mozilla recently announced the first round of winners from their Wireless Innovation for a Networked Society (WINS) challenges—$2 million in prizes for "big ideas to connect the unconnected across the US". According to the press release, the winners "are building mesh networks, solar-powered Wi-Fi, and network infrastructure that fits inside a single backpack" and that the common denominator for all of them is "they're affordable, scalable, open-source and secure."
  • New AirMozilla Audience Demo
    The legacy AirMozilla platform will be decommissioned later this year. The reasons for the change are multiple; however, the urgency of the change is driven by deprecated support of both the complex back-end infrastructure by IT and the user interface by Firefox engineering teams in 2016. Additional reasons include a complex user workflow resulting in a poor user experience, no self-service model, poor usability metrics and a lack of integrated, required features.

Games: All Walls Must Fall, Tales of Maj'Eyal

  • All Walls Must Fall, the quirky tech-noir tactics game, comes out of Early Access
    This isometric tactical RPG blends in sci-fi, a Cold War that never ended and lots of spirited action. It’s powered by Unreal Engine 4 and has good Linux support.
  • Non-Linux FOSS: Tales of Maj'Eyal
    I love gaming, but I have two main problems with being a gamer. First, I'm terrible at video games. Really. Second, I don't have the time to invest in order to increase my skills. So for me, a game that is easy to get started with while also providing an extensive gaming experience is key. It's also fairly rare. All the great games tend to have a horribly steep learning curve, and all the simple games seem to involve crushing candy. Thankfully, there are a few games like Tales of Maj'Eyal that are complex but with a really easy learning curve.

KDE and GNOME: KDE Discover, Okular, Librsvg, and Phone's UI Shell

  • This week in Discover, part 7
    The quest to make Discover the most-loved Linux app store continues at Warp 9 speed! You may laugh, but it’s happening! Mark my words, in a year Discover will be a beloved crown jewel of the KDE experience.
  • Okular gains some more JavaScript support
    With it we support recalculation of some fields based on others. An example that calculates sum, average, product, minimum and maximum of three numbers can be found in this youtube video.
  • Librsvg's continuous integration pipeline
    With the pre-built images, and caching of Rust artifacts, Jordan was able to reduce the time for the "test on every commit" builds from around 20 minutes, to little under 4 minutes in the current iteration. This will get even faster if the builds start using ccache and parallel builds from GNU make. Currently we have a problem in that tests are failing on 32-bit builds, and haven't had a chance to investigate the root cause. Hopefully we can add 32-bit jobs to the CI pipeline to catch this breakage as soon as possible.
  • Design report #3: designing the UI Shell, part 2
    Peter has been quite busy thinking about the most ergonomic mobile gestures and came up with a complete UI shell design.
