  • Linux 5.14 Drops Old DEC Alpha-Specific Binary Loader Used For x86 Binary Emulation - Phoronix

    As a weekend blast from the past, the Linux 5.14 kernel saw some Alpha CPU architecture updates -- including various fixes and the removal of an Alpha-specific binary loader for running a decades dated x86 software emulator.

    While past the merge window, the Linux 5.14 code this week has dropped "binfmt_em86" from the kernel. This is an Alpha binary loader for Linux focused on running i386/i486 binaries via the EM86 emulator in user-space. This was part of the effort for allowing Intel Linux x86 binaries back in the day to run on DEC Alpha hardware.

  • The New NTFS Driver Looks Like It Will Finally Be Ready With Linux 5.15 - Phoronix

    It's looking like the new NTFS file-system kernel driver developed by Paragon Software and over the past year revised more than two dozen times could be ready for mainlining in the kernel in about one month's time when the Linux 5.15 merge window opens. Everything is finally aligning and looking like the code is in good enough shape for its initial merging though not necessarily replacing the existing NTFS driver at this point.

  • Linux Changes Pipe Behavior After Breaking Problematic Android Apps On Recent Kernels - Phoronix

    At the end of 2019 a rework to the Linux kernel's pipe code saw some of its logic reworked to only wake up readers if needed and avoid a possible thundering herd problem. But it turns out some Android libraries abused the functionality and this has led to broken Android applications when moving to recent kernels. While the user-space software is in the wrong, the kernel is sticking to its policy of not breaking user-space and as such Linus Torvalds has changed the code's behavior for Linux 5.14 and to be back-ported to prior stable kernels.

    Rather than only waking up readers if needed, the change merged into the Linux kernel on Friday will make pipe writes always wake up readers. Due to some Android libraries like Realm misusing the EPOLL interface, the pipe change at the end of 2019 ended up breaking some Android apps.

  • Linux's FWUPD Expands Poly High-End Web Camera Support - Phoronix

    For those looking to purchase a high-end Linux-friendly web camera for your home office or other environment, there are a few more options now compatible with Linux's fwupd if interested in having the capability of updating the camera firmware under Linux.

    FWUPD has had support for updating firmware on the Poly Studio P30 web camera while now it's been expanded to handle additional Poly web cameras. This expanded Poly support can be found with the new FWUPD 1.5.12 release.

  • More RT Code Out For Review, RT Patches Updated Against Linux 5.14 - Phoronix

    The real-time (RT) patches for the Linux kernel still appear a ways off from mainline but at least there is movement on this important patch series for embedded and other use-cases needing real-time support.

    While mainlining the long out-of-tree Linux "RT" patches has been brought up many times in recent years, earlier this year the developers noted the mainlining has been held up by a lack of funding in getting the patches across the finish line. The PREEMPT_RT "development and maintenance is currently stalled" at least as was the case earlier this year but does seem to be loosening up a bit now.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
