  • Montréal-Python 76: Tonic Glacier

    At Montreal Python, we encourage you to stay at home - but not to stop writing Python ! This is why we are launching Montreal Python 76 - Tonic Glacier, a spectacularly virtual combo of a conference and, following a few days later, a hackathon to overcome COVID-19 with our keyboards.

  • The Singleton Design Pattern in Python

    In this article, we'll be diving into the Singleton Design Pattern, implemented in Python.

    As time progresses, software gets more tailored to solving specific problems in different domains. While there are many difference in the application-level of our software, some aspects of software design remain largely the same. These aspects might not remain the same for all software out there but will hold true for a lot of scenarios. Therefore, learning and understanding them will be highly beneficial in helping us build resilient programs.

    This is the first in a series about Design Patterns in Python and the different patterns that we can utilize to build software.

  • Python Docstrings

    In Python, a function is a group of related statements that performs a specific task.

    Functions help break our program into smaller and modular chunks. As our program grows larger and larger, functions make it more organized and manageable.

    Furthermore, it avoids repetition and makes the code reusable.

  • Multiple inheritance and mixin classes in Python

    I recently revisited three old posts on Django class-based views that I wrote for this blog, updating them to Django 3.0 (you can find them here) and noticed once again that the code base uses mixin classes to increase code reuse. I also realised that mixins are not very popular in Python, so I decided to explore them, brushing up my knowledge of the OOP theory in the meanwhile.

    To fully appreciate the content of the post, be sure you grasp two pillars of the OOP approach: delegation, in particular how it is implemented through inheritance, and polymorphism. This post about delegation and this post about polymorphism contain all you need to understand how Python implements those concepts.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
