‘Channels’ uses Django and extends its power beyond HTTP – to enable handling WebSockets, chat protocols, IoT protocols, and others. It is built on a Python specification called ASGI (Asynchronous Server Gateway Interface). ‘Channels’ is built on the native ASGI support provided in Django since v3.0, providing an implementation for Django v2.2. Django still handles … Read more Chapter 1 – Building a simple Real-Time stock market price tracker using Django Channels, Redis, Celery, and JavaScript
One of the most important stages in software design engineering is to understand the problem and establish a design scope. In many cases, when it comes to the back-of-the-envelope estimation, redundant requests towards the databases and/or the resources represent a tricky challenge that must be carefully taken into consideration if the product in question might … Read more Why Redis … in a few words
GitHub Actions is GitHub’s new build server, just like Gitlab’s gitlab pipeline. It allows you to automate your workflow directly from your GitHub repository, without having to configure and manage a third-party server like jenkins, Bamboo, CircleCI. For example, we can define an action that allows us to build our project and run a set … Read more Setup a CI/CD pipeline using Github Actions, Docker
This study shows you why the celery line is so relevant and how celery can be used in your Django app in conjunction with Redis.

Generative Pre-trained Transformer 3 (GPT-3) is an artificial intelligence model that uses deep learning to generate human-like English Text. A GPT-3 model is a very complex neuron network composed of billions of neurons, it has 175 billion parameters such as layers, number of neurons per layer, hidden layers, number of training iterations, etc.
When you deploy multiple containers each in a specific pod inside a Kubenetes Cluster, you’ll face new challenges compared to the monolith application concept. Each micro-service has its own business logic (BL), communication configs (COMM), retry logic (R), metrics – tracing logic (MT) as well as security logic (SEC). Therefore, managing those logics individually for … Read more Managing Communication Between Microservices Using Istio
