  • The Best Programming Language for Data Science: Python vs Julia vs R

    Programming language is practically the backbone of data science and in the modern advancement of technology, we have a lot of languages available at our expense. But the question is which one among them is the most suitable for a data scientist. Currently, the latest group of programming languages that data scientists use are Python, Julia, and R. All these languages have their unique attributes and they also have areas of expertise. For example, the Python ecosystem is loaded with libraries, tools, and applications that make the work of scientific computing and data analysis fast and convenient, but Julia aims to give scientists and data analysts not only fast and convenient development but also blazing execution speed. On the other hand, R language enhances the speed of statistical computing like no other.

  • LibreOffice With Linux

    A more advanced option is the other longtime go-to in the Linux world: LibreOffice. If you want to use it, you will have to install Linux on your Chromebook first. Then you can install LibreOffice in the default Debian installation using APT.

    sudo apt install libreoffice
    To launch LibreOffice Writer, just look for it in the app launcher, as you would with any other app. When you launch it, you'll see the standard OpenOffice Writer interface in all its clunky glory.

    You can then compose your document as on any other system. When you save it, don't forget to save it as a Microsoft Word document (DOCX), not the standard OpenOffice format (ODT).

  • 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.
