ReactOS 0.4.12 Released with Window Snapping, New Themes and Kernel Improvements

Monday 23rd of September 2019 04:37:00 PM
The ReactOS development team announced today the general availability of the ReactOS 0.4.12 open-source computer operating system compatible with Microsoft Windows binaries.

ReactOS 0.4.12 is here more than six months after version 0.4.11 to introduce window snapping, a feature that lets users snap windows to be aligned to sides, along with the necessary keyboard shortcuts, more robust and correct font rendering for buttons in various apps, two new themes, namely Lunar and Mizu, and support for Intel e1000 NIC.

"ReactOS now possesses a driver that supports this NIC out of the box instead of requiring end-users to manually find and install a driver, a finicky process if one does not have a working network connection in the first place. Furthermore, the new driver should also be compatible with e1000 NICs in real hardware," said Colin Finck.

    We are pleased to offer MX-19 for your use. As usual, this iso includes the latest updates from debian 10.1 (buster), antiX and MX repos.

  • Compact Apollo Lake SBC aims sky high

    Versalogic’s Linux-ready, sandwich-style “Harrier” SBC has an Apollo Lake processor and a compact 95 x 55mm footprint, ECC RAM support, and ruggedization features designed for high altitude UAVs. Versalogic announced a Harrier SBC due in Q1 2020 that revises the compact, COM-and-carrier design of its three-year-old, Intel Bay Trail based Osprey, but advances to the newer Intel Apollo Lake. The Osprey is similarly bereft of real-world ports to enable easier real-world deployments in constrained environments.

  • Red Hat Ceph Storage RGW deployment strategies and sizing guidance

    Starting in Red Hat Ceph Storage 3.0, Red Hat added support for Containerized Storage Daemons (CSD) which allows the software-defined storage components (Ceph MON, OSD, MGR, RGW, etc) to run within containers. CSD avoids the need to have dedicated nodes for storage services thus reducing both CAPEX and OPEX by co-located storage containerized daemons. Ceph-Ansible provides the required mechanism to put resource fencing to each storage container which is useful for running multiple storage daemon containers on one physical node. In this blog post, we will cover strategies to deploy RGW containers and their resource sizing guidance. Before we dive into the performance, let's understand what are the different ways to deploy RGW.

  • OpenShift 4.2: New YAML Editor

    Through our built-in YAML editor, users can create and edit resources right in the Red Hat OpenShift Web Console UI. In the latest release, we’ve upgraded our editor to include language server support. What is language server support? The language server support feature uses the OpenAPI schema from Kubernetes to provide content assist inside the YAML editor based on the type of resource you are editing. More specifically, the language server support offers the following capabilities: Improved YAML validation: The new editor provides feedback in context, directing you to the exact line and position that requires attention. Document outlining: Document outlines offer a quick way to navigate your code. Auto completion: While in the editor, language server support will provide you with valid configuration information as you type, allowing you to edit faster. Hover support: Hovering over a property will show a description of the associated schema. Advanced formatting: Format your YAML.
