  • MDN Changelog for July 2018: CDN tests, Goodbye Zones, and BCD

    We moved MDN Web Docs to a CDN in April 2018, and saw a 16% improvement in page load times. We shipped with 5 minute expiration times for MDN pages, so that the CDN will request a fresh copy after a short time. MDN is a wiki, and we can’t predict when a page will change. 300 seconds was a compromise between some caching for our most popular pages, and how long an author would need to wait for a changed page to be published to all visitors. 80% of visitors are getting an uncached page.

  • GSoC wrap-up - Splitting Servo's script crate

    The solution introduces a TypeHolder trait which contains associated types, and makes many structures in the script crate generic over this new trait. This allows the generic structs to refer to the new trait’s associated types, while the actual concrete types can be extracted into a separate crate. Testing shows significant improvement in memory consumption (25% lower) and build time (27% faster).

  • The Radeon "RADV" Driver Now Exposes Vulkan 1.1 On Android
    While the Mesa-based Radeon "RADV" Vulkan driver has been exposing Vulkan 1.1 since last year, the upcoming Mesa 19.1 will bring support for Vulkan 1.1 when this driver is active on Android systems. While the intersection of RADV driver usage on Android systems is quite low, this RADV Vulkan 1.1 support on Android comes following the merging of the YCbCr support into Mesa Git for the upcoming 19.1 release. Of the many additions to Vulkan 1.1 was YCbCr color formatted textures handling
  • Radeon Software for Linux 19.10 Adds Ubuntu 18.04.2 Support
    Radeon Software for Linux 19.10 was quietly released at the end of last week and seemed to go unnoticed until a Phoronix reader pointed out the existence of this updated hybrid driver featuring the AMDGPU All-Open and AMDGPU-PRO components. While being the first new release stream in quite a while to succeed the 18.50 series, the changes aren't all that noteworthy for what has been made public. The main change of Radeon Software for Linux 19.10 is now supporting Ubuntu 18.04.2 LTS, the latest Ubuntu LTS point release pulling in the graphics/kernel components from Ubuntu 18.10. So this should also allow the AMDGPU-PRO driver to work on Ubuntu 18.10 thanks to the shared components. This new driver release does not support the newly-minted Ubuntu 19.04 with AMD not supporting the non-LTS releases at least until those bits end up being found in an Ubuntu LTS point release.

GNU/Linux Domination in Devices

  • Survey reveals IoT developers' most-used tools
    The survey was carried out by the Eclipse IoT Working Group, a not-for-profit open source software organisation, in conjunction with its members – including Bosch Software Innovations and Red Hat. About three quarters of survey respondents used Linux for edge and gateway IoT devices, while about half used Windows. Debian and its derivatives Raspbian, Ubuntu and Ubuntu Core were the most-used Linux distributions.
  • Ubuntu is #1 for embedded & IoT
    The results are in! Eclipse.org recently published their 2019 IoT Developer Survey. Ubuntu is again the top choice for embedded & IoT, with our cousins Raspbian and Debian taking 2nd and 3rd respectively. The numbers fall off pretty steeply after that.
  • Development board with triple DP++ ports runs on Ryzen R1000
    Sapphire has launched an “AMD FS-FP5R 5×5” SBC with an AMD Ryzen Embedded R1000 SoC plus 2x GbE, 3x DP++, USB 3.1, SATA III, and M.2 expansion. Sapphire also sells two Ryzen V1000 based SBCs. Hong Kong based Sapphire Embedded Solutions is primarily known for its gaming and graphics cards, but it also has an embedded product line that runs on AMD embedded processors like the G-series and R-series. Now, the company has launched an AMD FS-FP5R 5×5 SBC with AMD’s new R-series successor, the Ryzen Embedded R1000. No OS details were listed, but Linux and Windows 10 are supported on two Sapphire SBCs built around the more powerful Ryzen Embedded V1000: the AMD FS-FP5V and more recent, Mini-ITX form factor AMD IPC-FP5V 10GbE (see farther below).

What's New In Xubuntu 19.04?

April is one of the months awaited by Ubuntu fans. Because this month is the schedule for the release of the latest version. Usually, in every 2 years, we will find Ubuntu releasing the LTS version with longer support. Ubuntu has released version 19.04 with code name Disco Dingo. This distribution is not included in the LTS category, so it only gets support for the next 9 months. However, many features are added in this version. You can see the detailed features added in here! Besides Ubuntu, other variants such as Xubuntu, Kubuntu and Lubuntu also released 19.04. And in this article I want to discuss about Xubuntu 19.04.
