  • How To Boot A Raspberry Pi 4 From An SSD

    In this tutorial, we’ll work through setting up a Raspberry Pi 4 to boot from a USB connected SSD or other USB storage media. There is quite a bit of information on this online already, but I’ve had a lot of questions recently about how to do this, so I thought I’d share my method.

    I’m going to be doing this on my latest plywood Pi case build with an M.2 NVME drive, but the process is the same for any USB attached solid-state, flash or disk drive. It also doesn’t matter what type of SSD you’ve got, as long as you’ve got an adaptor to convert the SSD interface to a USB interface, then you should be able to get your Raspberry Pi 4 to boot off of it.

  • How I keep my file folders tidy with Ansible | Opensource.com

    I try to use Ansible often, even for tasks that I know how to do with a shell script because I know that Ansible is easy to scale. Even though I might develop an Ansible playbook just for my personal workstation, sometimes it ends up being a lot more useful than intended, and it's easy to apply that same playbook to all the computers on my network. And besides, sometimes the greatest enemy of getting really good at something is the impression that it's only meant for serious professionals, or big projects, or whatever you feel that you're not. I use Ansible because it's a great open source tool, but I benefit from it the most because it scales.

  • How to find mixed Latin+Cyrillic words

    I thought confusions like these were interesting but unimportant oddities until I audited some UTF-8 data files from Russia. Some of the scientific names in those files were made up of mixed Latin and Cyrillic letters. A real-world example was "Aporreсtodea caliginosa caliginosa (Savigny, 1826)", in which the "c" in Aporrectodea was Cyrillic, not Latin.

    This had the potential to cause data-parsing errors, so I needed a way to find mixed Latin-Cyrillic words in the files I audit, which are all TSVs, UTF-8-encoded and mostly in Latin script.

  • 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.
