  • Your Desktop Wallpaper Just Got Interesting Again

    Komorebi 2 claims to be “faster, smoother, and better” than before. There are new features, a new codebase and (naturally) new wallpapers.

  • FFmpeg's VP9 Decoder Is Much Faster Thanks To GSoC 2017

    As we previously reported on, there was a Google Summer of Code project this year optimizing FFmpeg's VP9 decoder particularly around AVX2 instructions and threading. The project was a success and VP9 decoding should be much faster with FFmpeg as a result.

    GSoC '17 student developer Ilia Valiakhmetov spent his time optimizing the FFmpeg VP9 code for AVX (Advanced Vector Extensions) as well as implementing tile threading support. His AVX2 optimizations are already in FFmpeg Git while his tile threading code is still being reviewed.

  • Chromium Now Supports GPU Sandboxing With Radeon Graphics On Linux

    Chrome/Chromium supports GPU sandboxing for security purposes and now it will work fine with the AMD graphics on Linux.

    As explained in this Git commit that was just merged minutes ago, "Default sandboxing fails for AMD platform as the GPU process spawns multiple threads. So GPU sandboxing needs to be started early. And all dependent libraries need to be preloaded."

  • Open education: How students save money by creating open textbooks
    Most people consider a college education the key to future success, but for many students, the cost is insurmountable. The growing open educational resource (OER) movement is attempting to address this problem by providing a high-quality, low-cost alternative to traditional textbooks, while at the same time empowering students and educators in innovative ways. One of the leaders in this movement is Robin DeRosa, a professor at Plymouth State University in New Hampshire. I have been enthusiastically following her posts on Twitter and invited her to share her passion for open education with our readers. I am delighted to share our discussion with you.

Linux 4.10 To Linux 4.15 Kernel Benchmarks

The ThinkPad X1 Carbon has been enjoying its time on Linux 4.15. In addition to the recent boot time tests and kernel power comparison, here are some raw performance benchmarks looking at the speed from Linux 4.10 through Linux 4.15 Git. With this Broadwell-era Core i7 5600U laptop with 8GB RAM, HD Graphics, and 128GB SATA 3.0 SSD with Ubuntu 17.10 x86_64, the Linux 4.10 through 4.15 Git mainline kernels were benchmarked. Each one was tested "out of the box" and the kernel builds were obtained from the Ubuntu Mainline Kernel archive. Read more
