  • youtube-dl is too slow

    The world of YouTube downloaders is a kakistocracy and youtube-dl is the undisputed king.

    I've been using JWZ youtubedown instead for the past five years even though youtubedown is designed only to download files and I want links. With a few modifications I can make youtubedown produce links and it's faster than youtube-dl. Everything is faster than youtube-dl.

  • Using split DNS for websites hosted locally

    The dev.freshports.org website is hosted on server in my basement. For you, that IP addresses resolves to a publicly available IP address. For me, that IP address resolves to an RFC 1918 address:

    $ host dev.freshports.org
    dev.freshports.org has address 10.55.0.24

    Sometimes this is referred to as split dns, also known as split-horizon DNS, split-view DNS, split-brain DNS, or a fricking stupid thing to do).

  • Unlock encrypted disks on Linux automatically | Opensource.com

    Open encrypted disks without having to manually enter a passcode by using Network-Bound Disk Encryption (NBDE).

    From a security viewpoint, it's important to encrypt your sensitive data to protect it from prying eyes and hackers. Linux Unified Key Setup (LUKS) is a great tool and a common standard for Linux disk encryption. Because it stores all pertinent setup information in the partition header, it makes migrating data easy.

    To configure encrypted disks or partitions with LUKS, you will need to use the cryptsetup utility. Unfortunately, one of the downsides of encrypting your disks is that you have to manually provide the password every time the system is rebooted or the disk is remounted.

  • 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.
