Tech Tips, Tricks & Trivia

This Week I Learned -  * A literal disaster recovery - AWS operates 123 Availability Zones across 39 regions globally. One of the AWS Availability Zones in UAE was impacted by objects that struck the data center on March 1st. Vercel's Dubai region (dxb1) setup hosted on AWS me-central-1 is also impacted as a result. The event highlighted risks from physical incidents amid tense regional geopolitics. * Google Cloud is the only major hyperscaler without a data center in Dubai. *   S Anand shares his well-thought out AI prompts publicly on Github . Lots to learn & emulate. I love this prompt -  Think like an expert. In this context: - What patterns would an expert in this field check / recognize that beginners would miss? - What questions would an expert ask that a beginner would not know to? - What problems / failures would an expert anticipate that beginners may not be aware of? - How would an expert analyze this? At each step, explain what they are looking for and w...

This Week I Learned -  *  Supabase is an open-source Backend-as-a-Service (BaaS) built around PostgreSQL. It is a Firebase alternative that can help you set up a backend in less than 2 minutes. * Add the possibility of an Internet Service Provider-level blocking of a service to the list of things you should debug when your code isn't working. Now if your perfectly working code accesses some paid premium AI-Model APIs suddenly throws errors, you'll be losing tokens while you figure that it was in fact your ISP that was glitching.  A subset of users based in India accessing Supabase over JioFiber, Reliance Jio's fiber-to-the-home broadband service, faced routing/block issues. Supabase’s own infrastructure was fully operational but users on JioFiber (and some other Indian ISPs) couldn’t connect to Supabase services like Dashboard, Auth, Edge Functions, Postgres in ap-south-1, etc. The root cause turned out to be ISP-level DNS resolution failure. The ISP’s DNS serv...
