Supabase, acclaimed as an open-source alternative to Firebase, offers a comprehensive toolkit including database, authentication, and storage solutions. Excelling in crafting Minimum Viable Products (MVPs) and hackathon creations, it's particularly adept for building RAG (Retrieval-Augmented Generation) applications. In this guide, I'll demonstrate how to leverage Supabase to enhance your RAG application's efficiency.

Here's the workflow: Whenever a user uploads a document, we store its vector representation in Supabase. This vector acts as a unique fingerprint of the document's content. Later, when a query is raised, Supabase springs into action, searching for vectors that closely match the query. This search process efficiently retrieves the most relevant documents.

ChatGPT and similar large language models (LLMs) are currently at the forefront of every developer's mind, emerging as the latest trend in 'Silicon Valley'. The hype is real, and the possibilities are endless. But how do you get started? In this article, I will show you how to create a simple chatbot using ChatGPT and Voiceflow. I will also show you how to add it to your portfolio using Docusaurus.

Raspberry Pi, come out of the closet! It's time for you to shine! I'll show you how I give my Pi a good workout and I'll teach you how to do the same in this post. Let's get physical (with technology)!

Welcome to part 2 of our Flatiron Open Source adventure, where we will talk about our backend setup. We fully utilized Cloudflare in our project. We are going to explain this process step by step.

Flatiron School​

Flatiron School is a 15-week coding bootcamp, with courses in software engineering, data science, cybersecurity, and product design.

Upon completion of the course, students lose access to the internal class portal, called Canvas. Students are provided with html and javascript data files, containing information on the modules and courses used throughout the phases of the bootcamp.

Are you intrigued by networked note-taking apps?

Do you want to share your own knowledge base with everyone?

Have you heard about the digital garden craze sweeping the nation and want to make one of your own?

Maybe Obsidian + Netlify will be as good to you as they have been to me.

In this blog post, I describe the steps I took to set up this API, let's dive in!

If you continue to read this article, I assume that you know Ruby, OOP in Ruby, RoR, and Active Record. Yes, Postgresql support Array types to store. Based on their documentation:

PostgreSQL allows columns of a table to be defined as variable-length multidimensional arrays. Arrays of any built-in or user-defined base type, enum type, composite type, range type, or domain can be created. Let's start our journey! (I use Rails API-only as example, but this article can be implemented in normal Rails as well)

It doesn't matter if you are a beginner or a seasoned developer. From time to time, you need to look up certain programming language documentation to help you navigate through specific information to build up your application which then solves a definite task or problem. However, this skill is especially important for beginner developers since beginner developers, like myself, don't have many experiences in using built-in methods nor understanding how to implement the methods and the keywords to look for. For example, some methods require certain numbers of parameters, or even just simply land on the right page on the documentation.

Nowadays, security is very important on websites and apps. That's mainly to ensure that private data is not leaked to the public and someone doesn't do actions on your behalf.

Today, we are going to use Firebase, which is a BaaS that helps us with various services such as database authentication and cloud storage. We are going to see how we can use the authentication service in Firebase to secure our React app.
