  • Interviewed about microservices

    I got interviewed about Microservice and talk a bit about my last book, Hands-on Docker for Microservices with Python.

    I was an interesting view on what are the most important areas of Microservices and when migrating from Monolith architecture is a good idea. And also talking about related tools like Python, Docker or Kubernetes.

  • Passing a function as an argument to another function in Python

    One of the more hair-raising facts we learn in my introductory Python trainings is that you can pass functions into other functions. You can pass functions around because in Python, functions are objects.

    You likely don’t need to know about this in your first week of using Python, but as you dive deeper into Python you’ll find that it can be quite convenient to understand how to pass a function into another function.

    This is part 1 of what I expect to be a series on the various properties of “function objects”. This article focuses on what a new Python programmer should know and appreciate about the object-nature of Python’s functions.

  • “Microservices require a high-level vision to shape the direction of the system in the long term,” says Jaime Buelta

    To get an understanding of what exactly microservices are, when we should use them, when not to use them, we sat with Jaime Buelta, the author of Hands-On Docker for Microservices with Python. Along with explaining microservices and their benefits, Buelta shared some best practices developers should keep in mind if they decide to migrate their monoliths to microservices.

  • Quick Dive into Selenium with python

    Hi guys, I am chris, a software engineer and I have been building stuff with python since 2016.
    This would be a fast paced introduction to selenium.

    What is Selenium?

    In simple terms, selenium is a tool used to automate browsers, in even simpler terms selenium can be used to control broswers. To find out more visit the selenium site

  • Supercharge Your Classes With Python super()

    While Python isn’t purely an object-oriented language, it’s flexible enough and powerful enough to allow you to build your applications using the object-oriented paradigm. One of the ways in which Python achieves this is by supporting inheritance, which it does with super().

  • 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.
