  • Why You Should Use A Computer Specifically Meant For Bitcoin Transactions And How To Do It

    Tails is an operating system that boots from a USB thumb drive and temporarily takes over the hardware of any computer. It uses Tor connections only, so you’d need to be comfortable using Tor. None of the data that you write to memory during your session is saved to the drive (it starts fresh every time), unless you tweak the settings and create a permanent storage option (on the USB thumb drive), which you lock with a password.

    It’s not a bad option and it’s free, but it’s a little clunky for our purposes. Installing new software on it is not a breeze. One good feature is that it comes with Electrum, but the downside of this is that you didn’t install it yourself. Make sure the USB drive you use is at least 8GB.

    Your flexibility is reduced if you use Tails. You may not be able to follow various guides to set up what you need and get it working properly. For example, if you follow my guide to installing Bitcoin Core, there are modifications needed to make it work. I don’t think I’ll be making a Tails specific guide, so you’d need to build your skills and do it alone.

    I also am not sure how well hardware wallets will interact with this OS.

    Having said all this, a Tails computer for bitcoin transactions is a nice additional option, and it will certainly help your overall privacy skills to learn to use Tails.

  • 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.
