  • Fix Chromium signing out from Google under Linux Mint 20 :: Rafael Cavalcanti

    Recently, I started experiencing this issue on Chromium under Linux Mint 20.

    Every time I opened Chromium and tried to use a Google service, I would not be logged on them. For example, opening Gmail would show me the login page. I, then, proceeded to login, and everything worked fine until I closed the browser. Opening Chromium again would bring me back to the same problem: I was signed out from Google and prompted to login.

    This only happened to Google, other websites worked fine.

    Clearing the cache, trying different password stores and even deleting every Chromium file on my home directory and starting clean didn’t solve it.

  • Fix opening locked app from Termux on MIUI :: Rafael Cavalcanti

    Termux has the handy termux-open command, which is aliased as xdg-open. I use it to open markdown notes from Termux on Markor (a markdown editor application), by simply running xdg-open

    This stopped working when I set Markor to use MIUI’s “app lock” feature, which forces you to authenticate before opening selected apps. Termux would open Markor normally and the “app lock” screen would ask for my credentials. However, after logging in correctly, I would be brought back to Termux. Manually opening Markor wouldn’t show the file I opened.

  • Multi-line annotations on Taskwarrior :: Rafael Cavalcanti

    When I started using Taskwarrior, one of the first things that I missed was having plenty of space for writing my annotations.

    Of course, I could add \n's as I wished to break lines, but I wanted a comfier place to write them.

    I quickly stumbled upon a simple script that could solve that. It worked like this: you run it with the task number and your preferred editor opened with a blank screen, ready for your annotation. Now when you saved and closed it, your task was annotated. Very useful.

  • Issuing valid certificates for LAN-only websites :: Rafael Cavalcanti

    The scenario: you have some websites that only face your network. You want to enable SSL on them, and the certificate to be recognized out of the box on the clients, without the need for installing on each of them. For this, you have your own domain name.

    So a self-signed certificate is not an option, and you’ll probably want to use Let’s Encrypt. However, if you try Let’s Encrypt, the HTTP-01 challenge will fail, as your website doesn’t face the internet.

    A solution may be to use the DNS-01 challenge, but your domain DNS may not support it. In that case, what can you do?

  • 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.
