  • An unexpected character replacement

    A few weeks ago I found a replacement in GBIF that I'd never seen before: M<fc>ller. It was a hexadecimal value for the character "ü" enclosed in angle brackets. That particular hex value for "ü" appears in Windows-1252 and other encodings, but what program did this replacement? And why?

    Suspecting the worst, I did a search for other angle-bracket-enclosed strings in the dataset. The search turned up a lot of data items which had originally contained a non-breaking space, and which now contained that character's Unicode representation in brackets, for example Laevicardium. Excluding these, the result is shown here:

  • 40 Simple Yet Effective Linux Shell Script Examples

    Historically, the shell has been the native command-line interpreter for Unix-like systems. It has proven to be one of Unix’s major features throughout the years and grew into a whole new topic itself. Linux offers a variety of powerful shells with robust functionality, including Bash, Zsh, Tcsh, and Ksh. One of the most amazing features of these shells is their programmability. Creating simple yet effective Linux shell scripts for tackling day to day jobs is quite easy. Moreover, a modest knowledge over this topic will make you a Linux power user in no time. Stay with us to for a detailed introduction to Unix shell scripting.

  • Using PostgreSQL with Django

    Django is a high level full-stack open-source web framework written in Python, that encourages rapid development and clean, pragmatic design.

    Django, in its ‘out-of-the-box’ state, is set up to communicate with SQLite – a lightweight relational database included with the Python distribution. So by default, Django automatically creates an SQLite database for your project.

    In addition to SQLite, Django also has support for other popular databases that include PostgreSQL, MySQL, and Oracle.

  • 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.
