  • Digital Security Is as Easy as PGP

    Average computer users would be forgiven for not having any idea what PGP is. There is so much going on below the surface of the modern computing experience that even critically important security tools like PGP are tucked away.

    To be sure, there are specialized circles that make regular explicit use of PGP. Diligent Linux users would have at least a passing familiarity with PGP, since the fact that manufacturers didn’t install our OS for us means we have to verify its integrity ourselves.

    Otherwise, if your work doesn’t touch on information security, PGP would understandably be a mystery to you. But like I said, it is no less important for this reality. In fact, PGP played a significant part in why we have secure communications on the Internet. This actually isn’t because it’s widely used, although it definitely is utilized in software installation utilities the world over. Rather, its significance stems from its defiant challenge to an overzealous government that sought to compromise encryption long before most Americans used the Internet regularly.

    My aim in treating PGP here is twofold. The first is to shed some light on it for the uninitiated. The second, and more importantly, is to teach the daring among you how to wield this powerful tool. Hopefully, you found your way here after reading my security guide. If not, check out the last installment, and you will see that PGP can be useful in certain high-stakes threat scenarios.

    Before we proceed, keep in mind that, as with any tool, the usefulness of PGP adheres to the network effect. Its practicability is extremely limited due to scant adoption software development circles. If you seek to apply PGP toward interpersonal communication, those you communicate with must do the same.

  • 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.
