  • Encapsulation in Python

    Encapsulation is an essential aspect of Object Oriented Programming.

    Let’s explain encapsulation in plain words: information hiding. This means delimiting of the internal interface and attribute from the external world.

    The benefit of information hiding is reducing system complexity and increasing robustness.

    Why? Because encapsulation limits the interdependencies of different software components. Suppose we create a module. Our users could only interact with us through public APIs; they don’t care about the internals of this module. Even when the details of internals implementation changed, the user’s code doesn’t need a corresponding change.

    To implement encapsulation, we need to learn how to define and use private attribute and a private function.

  • Functional strategies in Python

    I got into a debate about Python’s support for functional programming (FP) with a friend. One of the challenging parts was listening to him say, “Python is broken” a number of times.

    Python is not broken. It’s just not a great language for writing pure functional programs. Python seemed broken to my friend in exactly the same way that a hammer seems broken to someone trying to turn a screw with it.

    I understand his frustration. Once you have fully embraced the FP mindset, it is difficult to understand why people would write programs any other way.

    I have not fully embraced the FP mindset. But that doesn’t mean that I can’t apply some FP lessons to my Python programs.

    In discussions about how FP and Python relate, I think too much attention is paid to the tactics. For example, some people say, “no need for map/­filter/­lambda, use list comprehensions.” Not only does this put off FP people because they’re being told to abandon the tools they are used to, but it gives the impression that list com­pre­hensions are somehow at odds with FP constructs, or are exact replacements.

  • How to use shared in-browser consoles to cooperate while working remotely.

    One of the challenges of remote work is when you need to work together on one thing.

    Our in-browser consoles are one of the core features of our service. Almost since the beginning, PythonAnywhere has been able to share consoles -- you entered the name of another user or an email address, and they got an email telling them how to log in and view your Python (or Bash, or IPython) console. If you use an email, the person you invite doesn't have to be PythonAnywhere registered user.

  • Python Vs JavaScript: Which One Should You Use For A Project?

    Are you confused which web app development technology is the right fit for you: JavaScript or Python? Do you want to know the real difference between these two most popular tools for web development? You have landed at the right place. In this blog, we will talk about various pros and cons of choosing these two languages as well as JavaScript vs Python performance and JavaScript vs Python speed and learning curve. In addition, we will compare these two languages on various parameters. So, let’s start:

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.
