  • Linus Torvalds On Fun, the Linux Kernel, and the Future

    Linus Torvalds, creator of the Linux kernel, took to the stage at Open Source Summit in Los Angeles. In this keynote presentation, Torvalds joined The Linux Foundation Executive Director Jim Zemlin in conversation about Linux kernel development and how to get young open source developers involved. Here are some highlights of their talk.

  • Collabora & Linux Kernel 4.13

    Linux kernel 4.13 is out and - like in the 4.12 release - 12 Collabora developers contributed a total of 72 patches. In addition Collabora developers provided 25 Reviewed-by tags and 10 Tested-by tags. Furthermore 83 patches received a Signed-off-by tag from Collabora peoples. Again, general information about the merge window is available by LWN.net in form of the following articles: part 1 and part 2.

  • A Quick EXT4 Run With Linux 4.14 Git

    After the Linux 4.14 merge window is over, I'll begin with a lot of fresh Linux kernel benchmarks from this in-development release. But I/O and EXT4 changes already have me running some preliminary tests.

    With EXT4 are some scalability improvements to note. The scalability improvements around allocating inodes may help in some workloads. I received a report of this patch on a consumer SSD helping out the Phoronix Test Suite's BlogBench. There's also been some talk of other performance changes to find in Linux 4.14.

  • Core i9 7900X vs. Threadripper 1950X On Ubuntu 17.10, Antergos, Clear Linux

    While we have already compared the Threadripper 1950X to the current top-end Core i9 7900X processor, today we are taking things a step further with our Threadripper Linux benchmarks by doing a side-by-side showdown when each system is tested across three different Linux distributions.

    Here is a multi-way comparison when running the Threadripper 1950X and Core i9 7900X under Ubuntu 17.10 with its latest daily snapshot as of testing, Antergos 17.9 Rolling, and Clear Linux 17650. This provides a diverse look at the performance across distributions for these high-end desktop processors.

  • 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
