  • Jonathan McDowell: Mainline Linux on the MikroTik RB3011

    I upgraded my home internet connection to fibre (FTTP) last October. I’m still on an 80M/20M service, so it’s no faster than my old VDSL FTTC connection was, and as a result for a long time I continued to use my HomeHub 5A running OpenWRT. However the FTTP ONT meant I was using up an additional ethernet port on the router, and I was already short, so I ended up with a GigE switch in use as well. Also my wifi is handled by a UniFi, which takes its power via Power-over-Ethernet. That mean I had a router, a switch and a PoE injector all in close proximity. I wanted to reduce the number of devices, and ideally upgrade to something that could scale once I decide to upgrade my FTTP service speed.

  • Which file systems support file cloning

    OpenZFS isn’t part of the Linux kernel because of licensing issues, and that is unlikely to change. OpenZFS doesn’t support any of the relevant Linux syscalls for cloning files or blocks. It doesn’t offer a replacement for these syscalls on FreeBSD or Linux. (This is why there are no out-of-band deduplication tools for OpenZFS.)

    Bcachefs isn’t in the kernel yet either, but it’s developed under a Linux-kernel compatible license with the ultimate goal of being merged into the kernel. It supports all the relevant Linux-specific syscalls for file cloning.

    Over the last three years, Apple has switched all of its products to its new CoW-based Apple File System (APFS). Microsoft has decided to go in the opposite direction, and removed its copy-on-write file system, ReFS, from Windows 10 Professional in 2017. ReFS is now only available on Workstation and Server editions. ReFS was not suitable for use on Windows desktops anyway. This does leave Windows as the only computer operating system without a CoW file system.

    I find file cloning fascinating, and I’ll explore several potential use cases for it in the coming weeks. Next up will be how you can identify a cloned file. Something that is surprisingly difficult because the file system doesn’t keep track of it.

  • Intel Platform Monitoring Telemetry Appears Destined For Linux 5.10

    As first outlined earlier this year, Intel has been working on the Linux support for Platform Monitoring Technology as a new hardware telemetry feature first introduced with new Tigerlake hardware. It's looking like the initial Intel PMT support will come with Linux 5.10 while further work is being prepared that builds off its foundation.

  • Announcing updated Oracle Linux Templates for Oracle Linux KVM

    Oracle is pleased to announce updated Oracle Linux Templates for Oracle Linux KVM and Oracle Linux Virtualization Manager.

    Oracle Linux Templates for Oracle Linux KVM provide an innovative approach to deploying a fully configured software stack by offering pre-installed and pre-configured software images. Use of Oracle Linux Templates eliminates the installation and configuration costs, and reduces the ongoing maintenance costs helping organizations achieve faster time to market and lower cost of operations.

    [...]

    New Oracle Linux Templates for Oracle Linux KVM and Oracle Linux Virtualization Manager supply powerful automation. These templates are built on cloud-init, the same technology used today on Oracle Cloud Infrastructure and includes improvements and regression fixes.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
