  • Google’s ‘Seesaw’ Load Balancer Goes Open Source

    If you’re a network or systems administrator, you’re likely familiar with the concept of a load balancer. It’s a hardware device or software stack that distributes network application load across all the machines and servers connected to it in order to help mitigate network congestion. Google’s software solution, called Seesaw, was created in 2012 in response to a lack of adequate load balancing software for Google’s own use. Coded in Google’s own Go language, the software boasted a flexible Linux backbone and was used to manage Google’s own network needs, which entailed things like automated deployment and ease of use and maintenance.

  • Google Open Sources Its Seesaw Load Balancer

    Google announced today that it is open-sourcing Seesaw — a Linux-based load balancing system. The code for the project, which is written in Google’s Go language, is now available on GitHub under the Apache license.

    As Google Site Reliability Engineer Joel Sing, who works on the company’s corporate infrastructure, writes in today’s announcement, Google used to use two different load balancing systems back in 2012. Both, however, “presented different sets of management and stability challenges.” So to fix this, he and his team set out to find a new solution and because the ones available at the time didn’t meet Google’s needs, they started writing their own.

  • 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
