  • Python Datetime Module

    The datetime module provides classes for manipulating dates and times. There can be numerous applications that require processing dates and times. The datetime module is very useful for dealing with different types of dates and times format.

    The date and time objects can be either categorized as aware or naive depending on whether or not they include timezone information.

    An aware object can identify itself relative to other time objects with the help of other parameters such as timezone and daylight saving information.

    A naive object on the other hand doesn't contain enough information to identify itself to other date/time objects.

    Datetime objects have an optional timezone information attribute tzinfo which we will cover later. The tzinfo lets us handle offset from UTC time, timezone name and whether daylight saving time is in effect.

    With the Linux 5.15 kernel merge window likely opening next week, Matthew Wilcox of Oracle has already sent in a prominent pull request to Linus Torvalds: the initial work around landing of the memory folios patches.

  • 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.
