  • Sven Hoexter: PV - Monitoring Envertech Microinverter via envertecportal.com

    Some time ago I looked briefly at an Envertech data logger for small scale photovoltaic setups. Turned out that PV inverter are kinda unreliable, and you really have to monitor them to notice downtimes and defects. Since my pal shot for a quick win I've cobbled together another Python script to query the portal at www.envertecportal.com, and report back if the generated power is down to 0. The script is currently run on a vserver via cron and reports back via the system MTA. So yeah, you need to have something like that already at hand.

  • Some site updates

    We’re in the process of upgrading to Debian 11 (bullseye). If you come across any issues, feel free to raise them on the #debian-social IRC channel on oftc (also accessible via Matrix) and we’ll look into it as soon as we have a chance.

  • Matrix Synapse updated and new plumbed IRC rooms

    Matrix synapse was updated to 1.40.0, during the upgrade the server was upgraded to Bullseye.

  • Infrastructure in place to run each app as a separate user

    Running an app as a non-root user also means that it can't write just anywhere in the filesystem, can be constrained to only write in its own home folder. And if required, can be prevented from reading critical files.

    Of course Easy already has "crippled root" in containers, so running, say, SeaMonkey, on the main desktop as a non-root user would have to be seen as an alternative security strategy. SeaMonkey will run a little bit faster, and won't have the issues that some people have reported with running SM in a container, such as problem with network connectivity.

    If each app is run as its own user, this means that EasyOS can implement a permissions management GUI like in Android. Like, do you want this app to be able to access the camera, network, audio, folders outside the "home" folder? ...etc.

    So, have started to setup the infrastructure to support this. The idea is that top-level /clients folder will have these non-root users, though I would like to refer to them as "clients".

  • 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.
