Getting started with Celery and Python
In this post, I am going to talk about Celery, what it is, and how it is used. What is Celery From the official website: Celery is a simple, flexible, and reliable distributed system to process vast amounts of messages, while providing operations with the tools required to maintain such a system. Wikipedia says: Celery is an open source asynchronous task queue or job queue which is based on distributed message passing. While it supports scheduling, its focus is on operations in real time. In short, Celery is good to take care of asynchronous or long-running tasks that could be delayed and do not require real-time interaction. It can also…

Develop Ali Express Scraper in Python with Scraper API
This is another post in ScrapeTheFamous, in which I will be parsing some famous websites and will discuss my development process. The posts will be using Scraper API for parsing purposes which makes me free from all worries about blocking and rendering dynamic sites since Scraper API takes care of everything. In this post, we are going to scrape AliExpress. AliExpress is a Chinese B2C portal to buy stuff. The script I am going to make consists of two parts, or I say, two functions: fetch and parse. The fetch will accept a category and return all links of individual items and parse will parse an individual entry and returns a few data points in…

Using Apache Airflow ETL to fetch and analyze BTC data
This post is part of the Data Engineering and ETL Series. I am taking a short break from Blockchain-related posts. In the past, I have covered Apache Airflow posts here. In this post, I am discussing how to use the CCXT library to grab BTC/USD data from exchanges and create an ETL for data analysis and visualization. I am using the dockerized version of Airflow. It is easy to set up and use proper different images to run different components instead of a one-machine setup. The docker-compose.yml file is available here but I have made a few changes to install custom libraries. Therefore, it is advised you use the file I have…

The video demo of this project can be seen below: In this post, I will be discussing how to mint ERC721 NFT tokens and then integrate them with new or existing websites.

Visualizing Python modules and dependencies with Neo4j
I am taking a short break from the Blockchain Programming series and writing this post because I found it pretty interesting. The other day I found a tweet(which unfortunately I forgot to bookmark and can’t find it anymore) about visualizing python modules in Neo4J. Guido, the Python creator had responded to that tweet. That tweet got stuck in my mind and I thought it a great excuse to explore Neo4j. I had been thinking of exploring some Graph Databases other than Neo4j. For some weird reason, I had been ignoring Neo4j for a long time, most probably because of the Java thing which I do not like at all. I…
