postmarketOS 22.06 aims to revive end-of-life smartphones

A Linux distro for smartphones abandoned by their manufacturers, postmarketOS, has introduced in-place upgrades.

Alpine Linux is a very minimal general-purpose distro that runs well on low-end kit, as The Reg FOSS desk found when we looked at version 3.16 last month. postmarketOS's – pmOS for short – version 22.06 is based on the same version.

This itself is distinctive. Most other third-party smartphone OSes, such as LineageOS or GrapheneOS, or the former CyanogenMod, are based on the core of Android itself.

The project is quite different. It uses the mainline Linux kernel, and a standard userland, to support a wide variety of devices. The theory is that not needing a manufacturer's outdated firmware or drivers means that pmOS can use more current components, direct from the various upstream Linux projects. The project's own wiki currently lists over 200 supported devices, including phones, tablets, and e-book readers, ranging back to the venerable Nokia N900.

They're not all equally supported, though. Most of them can can boot, many have Wi-Fi support, but currently just two actual phones work as phones: the open-source hardware PinePhone and the Purism Librem 5. Even saying that, though, the ability to connect to Wi-Fi and use an old device as a pocketable terminal could make obsolete hardware useful again.

  • 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.
