• Libjpeg-Turbo 2.0 Beta Brings More AVX2 SIMD, Improved CMake Build System

  A Phoronix reader recently pointed out that LibJPEG 2.0 Beta quietly shipped last month as working towards the next big update for this speed-focused JPEG library. Libjpeg-Turbo 2.0 beta is available for testing and it brings AVX2 SIMD support for colorspace conversion, chroma downsampling/upsampling, integer quantization and sample conversion, and integer DCT/IDCT algorithms. These AVX2 SIMD accelerated paths are generally bringing gains anywhere from 9% to 36% faster depending upon the operation. This version is also bringing SIMD acceleration for Huffman encoding on SSE2 CPUs and Loongson MMI SIMD implementations for more functions.

• A look at Rancher 2.0

  Last December, we announced a Kubernetes Cloud Native Platform in partnership with Rancher Labs. Built on Canonical’s Distribution of Kubernetes and Rancher 2.0, the Cloud Native Platform will simplify enterprise usage of Kubernetes with seamless user management, access control, and cluster administration. Join our webinar to get a tour of the platform!

• DragonFlyBSD Kernel Gets Some SMP Improvements

  It looks like the DragonFlyBSD 5.4 release will be delivering at least a few kernel-level performance improvements. It turns out just hours after wrapping up the latest BSD vs. Linux benchmarks, Matthew Dillon pushed a few performance tweaks to the Git tree for DragonFly.

• Best Open Source 3D Printers

  In simplest terms, an open source 3D printer refers to a 3D printer whose hardware and software information are available to the public, typically under a license. The information can be used by anyone to build, modify, or improve the 3D printer. If you’re looking for real open source 3D printers, then you’ve come to the right place. In this guide, we introduce you to completely open source 3D printers. The hardware and software information of all the products listed here can be easily found on the internet.

Microsoft Linuxwashing and Research Openwashing

• Microsoft Calls On Linux for Its New IoT Security Platform [Ed: When Microsoft exploits Linux it's for lockin which requires that you buy a licence for Windows, Visual Studio etc. while paying Microsoft rents.]

• Microsoft Improves Linux Subsystem Security; Adds Windows Defender Firewall Support [Ed: No, FOSSBytes, Microsoft just puts GNU/Linux with limited functionality inside a keylogger (Vista 10) with back doors, then markets that as "security" for dumb writers to repeat]

• Researchers Deliver Open-Source Simulator For Cyber Physical Systems

  Cyber physical systems (CPS) are attracting more attention than ever thanks to the rapid development of the Internet of Things (IoT) and its combination with artificial intelligence (AI), machine learning and the cloud. These interacting networks of physical and computational components will provide the foundation of critical infrastructure, form the basis of 'smart' services, and improve the quality of life in areas ranging from energy and environment to transportation and healthcare.
