Nothing against this content creator in particular (they are an outcome of a social system, and are one among millions) - but like wow, this is a lot of “skilled labour” going into this type of work - but to what end exactly?

Imagine you land in Bangalore from outside India. Let's connect to the airport wifi. Oh nice, there are two of them. "BLR Free Wifi" - the name is self evident, lets try. Oh no, no captive portal. 😖 Ok PM WANI - whatever it might mean - lets try this too. "You need this special app access this" How to download said app without internet in the first place? 🤯 Bonus: Even if BLR Free WiFi captive portal worked like before, it would require OTP Bonus 2: The PM WANI app looks super sketchy with 3 bland screenshot, and zero reviews

You can now just stare at an UPI QR code till your bill is paid. (Meta Ray Bans can scan the QR code and pay it via your Whatsapp UPI account) Try it next time when paying and see the shocked reaction of the shopkeepers 😅

Absolutely hooked on to a Instagram multi part thriller series on Toty the street dog who picks fights with street dogs from other localities. 🤣🤣🤣 Next level content. Netflix has nothing on this.

It has been a long time since I made a video. I am sharing a deep dive into 2fac, a new 2FA app I built to replace Authy. What makes this project special is its massive scope, running natively across Android, iOS, watchOS, desktop, CLI, browser extensions, and the web. Building this many features across so many platforms was only possible through agentic coding. Huge thanks to Copilot, Claude, OpenCode, and Pi for completely changing how I write software. Here is what is covered in the video. In the pre-AI world, so many features, taking it to such a polished state (ui, design, relialibility of how it works, and quality of code too, you can take a look for yourelf) single handedly, that too working on spare time on the side from a day job, was simply not possible for non 10x, mid engineers like me 00:00:00 Project Overview & Motivation 00:03:31 Android App Demo 00:04:19 iOS & watchOS App Demo 00:05:32 Desktop App Demo 00:06:05 System Tray Integration 00:07:05 CLI Demo 00:08:44 Browser Extension Demo 00:10:00 Web App (PWA) Demo 00:11:40 Secure Unlock & Passkeys 00:16:30 GitHub Repo & Release Plans 00:17:30 CI/CD Pipeline Setup 00:19:00 AI Agentic Coding Workflow 00:23:50 Production Usage Warning 00:26:00 Custom AI Agent Skills 00:28:30 Automated Planning & Roadmaps 00:31:14 UI Testing with Maestro 00:35:12 Creating Custom AI Agents 00:38:34 Codebase Test Coverage 00:41:30 AI-Driven TDD

A short demo of how I use these extensions that I created for myself in Pi - pi-context-prune - pi-context-usage - pi-cache-graph (they are all on npm if you want to install for yourself)

IPL season is upon us soon, and what better way to restart Season 2 of #ScalerPod than to talk about challenges of scaling up Fantasy Sports platforms to hundreds of millions during sports seasons! Catch me in conversation with Amit Sharma from Blog - coming tomorrow!

People have asked why would Netflix crash with Mike Tyson and Jake Paul at 5-6M streaming it when they have 300M users and 100M view Squid Game series drop on day 1? Well live and recorded content works different. Hacked together a quick explainer on my phone for this.

As you watch results and counting on JioCinema today you can browse through an extensive set of data from every constituency which the team has added below the video - key battles - leads and results of counting - detailed stats of past elections - candidate information

I would simply have not gotten a side project of this size and scale off and running with an MVP out of the door in less than 2 weeks without Claude Code, Cursor, Junie etc (+blog post by Gemini) I don't care about AGI, the coding productivity unlock is right here, right now.

Me to junior dev: You’re getting stuck on very basic stuff, why don’t you RTFM before you use a framework? Junior Dev: I have watched the React docs on TikTok Me: Wtf does that even mean? Junior Dev:

AI truly unlocks experiences that were just unimaginable before. For example I liked playing a game but I wanted to build a slightly different version of the game with some changes. 4 hours with Claude Code, Gemini 3 and Copilot, and I am easily 50% there to an MVP.

In my latest #ScalerPod episode where I had Rahul Chari as the guest - asked the one question everyone wants to ask fintech founders - "Do you want to become a bank?" Check out the full episode to hear his detailed answer to why does he not want to become a bank.

It is so over. And we are so back. I get why Varun Mayya makes videos with AI clone now. I love writing text - but people love watching videos. And AI can bridge this gap now! Even the introverts can be podcast bros now.

Reached 150k population for the first time on Cities Skylines 2. The game starts to get really choppy after ~120k though. It was interesting to see, how initially GPU was at 100% utilisation but CPU at 10% and by the time you reach 100k population, even CPU cranks up to 50%
