2. Exploring competitive features in Node.js v18 and v19
Written by Stanley Ulili✏️

Node.js has been a popular JavaScript runtime since its release in 2009. But the advent of two new runtimes, Deno and Bun, has brought a lot of hype for the new features they present in contrast to Node.

From afar, it may seem like Node.js is stagnating and nothing exciting is happening — but the reality is different. Two recent Node.js releases, v18 and v19, came with a lot of significant features:

2. Nairobi Stock Exchange Web Scraper (MongoDB Atlas Hackathon 2022 on DEV)
What I built

I built a web scraper using Python (specifically the Scrapy Framework and Beautiful Soup library), MongoDB Atlas as the database, Atlas Charts for data visualization and Africas Talking as the SMS API. The web scraper scrapes the NSE website for the latest stock prices and stores them in a MongoDB Atlas database. The data is then retrieved from the database and sent to the user via SMS.

Additionally I added CI/CD to the project using GitHub Actions. The CI/CD pipeline runs the tes…

Welcome gentle reader. My name is Silent-Mobius, also known as Alex M. Schapelle. Today I'd like to introduce you a small project that I have developed while tinkering with various tools.

In this quest of proof of concept, we set to prove that python/flask application can be used to manage working node of Linux Distribution while running docker-compose environment.

Initial recognition is due, to one @andreagrandi, who inspired me for this project, thus: Thank you for your docker-puller project…

1. How to Validate Password Strength Using Regex and JavaScript
Validating the strength of a password is an important step in ensuring the security of user accounts. One way to do this is by using regular expressions (regex) and JavaScript.

To start, let's define what we mean by a strong password. A strong password is typically one that is difficult for someone else to guess or crack. This can be achieved by using a combination of upper and lower case letters, numbers, and special characters, and having a minimum length of at least 8 characters.

Now let's …

2. Deploy AI Models with RabbitMQ Message Broker
⚠️ Disclaimer

This blog is focused on the situation when you need to handle a low number of users to access your AI models, like in a hackathon or a prototype of a product which may not be accessed by more than 500s people concurrently. More optimization and robust design are required for production usage. But this blog can be a good starting point.

🏊 Let's discuss the problem with Client-Server architecture.

We all know maximum AI models are resource-hungry operations and take at least from…

1. The Fastest Way to Generate QR Codes: The QR Generator API
Hey everyone,

I'm excited to announce that I have just released my first API - the QR Generator API! This API allows users to easily create QR codes for any purpose, such as linking to a website, sharing contact information, or accessing digital coupons. The API is simple and easy to use, and requires no technical expertise. All you need to do is send a GET request to the API endpoint with the URL or string that you want to encode, and receive a response with the QR code image.

To build the QR…
