  • Setting up a ThinkPad x250 with Linux

    Two chapters in this article are Debian-specific, the rest is more or less Archlinux-specific. It never grew into the device-specific alround tutorial I envisioned and has been partially superseded by this article. The ThinkPad itself is in daily use. No regrets there!

  • How to Install Fish Shell on CentOS 8 and Rocky Linux 8 – VITUX

    Fish Shell also known as ‘Friendly interactive shell’ used for Unix/Linux-like operating distributions. It provides a smart, fully equipped, and user-friendly command-line environment for all Linux users. Fish shell supports various features unlike any other shell such as autosuggestion, Tab completion, syntax highlighting, Sane Scripting, Glorious VGA Color, and web-based configuration. Using this interactive shell environment, you do not need to remember a bunch of Linux commands because it is more productive and comes with various handy features. We will talk about the installation of interactive Fish Shell on CentOS 8 in this tutorial. The same steps apply to Rocky Linux and AlmaLinux too.

  • How to disable Special keys Windows 10 (Sticky keys) | ITIGIC - TechStony

    They are keys that exist since the first versions of Windows and continue in the most recent versions, including Windows 10. Therefore, we are going to tell you what the special keys or Sticky Keys consist of and how to deactivate them because you have already tired of having them in your computer (or because they hinder you).

  • How to install Devuan(II) - Unixcop

    In this article I show how to install Devuan using the installer included in the desktop-live iso, refractainstaller. In a previous article I’ve showed how to install it using the net-install ISO. From the devuan site: Devuan GNU+Linux is a fork of Debian without systemd that allows users to reclaim control over their system by avoiding unnecessary entanglements and ensuring Init Freedom.

  • How to install and configure NextCloud on Centos 8 and LEMP

    In this guide, we are going to set up NextCloud on a Centos 8 server hosted with Nginx and php (LEMP stack). We will be using Mysql 8 and PHP 7.4 for this guide.This will also work for RHEL derivatives like Alma Linux 8, Rocky Linux 8 and RHEL 8. Nextcloud is an Open Source suite of client-server software for creating and using file hosting services. It is a a free self-hosted cloud storage solution similar to Dropbox, Google Drive, etc. With Nextcloud, you don’t have to worry about the pricey alternatives and since you will host your own files, you don’t have to worry about privacy or someone collecting your data.

Kernel: Paul E. Mc Kenney and New Stuff in Linux

  • Paul E. Mc Kenney: TL;DR: Memory-Model Recommendations for Rusting the Linux Kernel

    These recommendations assume that the initial Linux-kernel targets for Rust developers are device drivers that do not have unusual performance and scalability requirements, meaning that wrappering of small C-language functions is tolerable. (Please note that most device drivers fit into this category.) It also assumes that the main goal is to reduce memory-safety bugs, although other bugs might be addressed as well. Or, Murphy being Murphy, created as well. But that is a risk in all software development, not just Rust in the Linux kernel. Those interested in getting Rust into Linux-kernel device drivers sooner rather than later should look at the short-term recommendations, while those interested in extending Rust's (and, for that matter, C's) concurrency capabilities might be more interested in the long-term recommendations.

  • Cluster Scheduler Support Queued Ahead Of Linux 5.16 - Phoronix

    Cluster scheduler support has been queued up for landing in the Linux 5.16 kernel for AArch64 and x86_64 systems for improving the CPU scheduler behavior for systems that have clusters of CPU cores. The cluster scheduler support in this context is about enhancing the Linux kernel's scheduler for systems where sets of CPU cores share an L2 cache or other mid-level caches/resources. This cluster scheduler work stems from work by HiSilicon and Huawei aiming to improve the Linux performance for the Kunpeng 920 server chip. That HiSilicon SoC has six or eight clusters per NUMA node with four CPU cores per cluster and a shared L3 cache. With the cluster scheduler patches they were able to enhance the overall performance of the system and also improve the efficiency.

  • AMD Finally Enabling PSR By Default For Newer Hardware With Linux 5.16 - Phoronix

    With it getting late into the Linux 5.15 kernel cycle, the focus is shifting by the Direct Rendering Driver maintainers from new feature work targeting the next cycle (5.16) to instead on bug fixes. AMD sent out a pull request of new AMDGPU Linux 5.16 material this week that is primarily delivering bug fixes but one notable addition is finally enabling PSR by default for newer GPUs.

  • Intel Compute-Runtime 21.41.21220 Ships Updated DG1 Support - Phoronix

    Intel's open-source engineers have shipped Compute-Runtime 21.41.21220 as the newest version of this Linux compute stack enabling OpenCL and Level Zero support with their graphics processors. Intel Compute-Runtime 21.41.21220 is the latest weekly update for this compute stack. New this week is updated DG1 platform support and Level Zero support for SPIR-V static module linking.

OpenSSH, Squid, PostgreSQL Update in Tumbleweed

Three openSUSE Tumbleweed snapshots released this week have brought updates for text editors, browsers, emails clients, database management systems and many other pieces of software. Mozilla Firefox, Thunderbird, nano, and PostgreSQL were all in the latest 20211012 snapshot. A new major version of Firefox 93.0 added support for the optimised image format AVIF, which offers a significant file size reduction as opposed to other image formats. The browser also improved web compatibility for privacy protections and fixed more than a handful of Common Vulnerabilities and Exposures. Thunderbird 91.2.0 addressed many of the same CVEs, fixed some issues with the calendar and fixed the new mail notifications that did not properly take subfolders into account. The 5.9 version of text editor nano added syntax highlighting for YAML files and fetchmail 6.4.22 added a few patches, addressed a CVE related to an IMAP connections and now highlights being compatible with OpenSSL 1.1.1 and 3.0.0. The new major version of postgresql 14 provided improvements for heavy workloads, enhanced distributed workloads and added a couple more predefined roles like pg_read_all_data, pg_write_all_data and pg_database_owner. Other packages to update in the snapshot were GNOME’s document viewer evince 41.2, Flatpak 1.12.1, graphics library gegl 0.4.32, glusterfs 9.3 and many RubyGems and YaST package updates.
