I’ve had Indian friends who immigrated to the US ask me if I have experienced racism growing up here. My answer is that I have experienced less racism in the US than most Indians have expressed towards all of their Asian neighbors.

It's been 9 months since @karpathy coined the term "vibe coding" and now we're seeing the result: App AI slop. My social media feed is full of ads for AI powered apps that must have been quickly vibe coded and distributed to the mobile app stores.

It's nearly impossible for old, established companies to change their product and operations to adjust to a fundamental shift in customer behavior. For a while it looked HBO, Disney, etc would pull it off and actually compete with Netflix because of their content backlog and

I spent the last day trying to vibe code an iOS app using @expo and @cursor_ai. I had good success vibe coding a React/Typescript/Django app so thought I'd see what would happen if I tried a mobile app. I had built a few toy apps in native iOS over 5 years ago but hadn't touched

Google AI Studio seems to have better rate limits for Gemini as the audience is devs. But it is clear that Google hasn’t really tried to monetize or integrate Gemini heavily into their consumer or enterprise products yet. They’ve stay focused on nailing the frontier model first.

Mamdani handled Trump like every Indian kid who learned to respectfully handle an opinionated Indian Aunty or Uncle at a dinner party. Quiet deference without getting unnecessarily combative when it’s better to just let them rant and lecture.

This is true until there’s a clear need for specialists in things like HR, finance, engineering, and legal. The hard part is knowing when you’ve crossed this threshold and it’s time to hire a specialist. Hopefully it’s before shit hits the fan.

The Epstein files will be our generation’s JFK files. We won’t know what happened, but maybe our kids will know in their 40s. And by then no one will really give a shit.

It's interesting watching the political aftermath of yesterday's election results and how things are playing out among Democrats and Republicans. Both sides are dealing with their extremists wanting to double down on extreme policies. For Republicans, it's white nationalism and

There probably needs to be a federal law equivalent to Section 230 to limit the liability for foundational model companies if people take their medical or legal advice.

fake news. chatgpt will still give you health and legal advice. what happened was openai updated its acceptable usage policy last week and said you can’t use chatgpt to provide legal and medical advice if you’re not a lawyer or doctor. totally different thing.

Some tech companies hire engineers slowly. Every interview is highly curated, feedback is scrutinized, and there are often several layers of bureaucratic approvals to get a hire approved. Other companies hire faster. Managers make a hiring decision based on interviews, feedback,

I know a few people who've done this. And honestly, it changed them. They got way better at avoiding work than actually doing work. They got better at looking over their shoulder than learning to trust their coworkers. They got more jaded and pessimistic over time. At some

A long, but explosive read. The TL;DR is that Anthropic and Cursor both have unsustainable business models at today’s pricing. If they raise prices, demand will shift to OpenAI and Gemini. But likely those companies are also under similar pressure.

Exclusive: Anthropic spent $2.66 billion on Amazon Web Services in the first three quarters of 2025, around 100% of their estimated revenue. Its costs appear to increase with their revenue, showing little path to profitability. https://t.co/2Sxmx9N4YO

HugOps to all the folks dealing with the AWS outage. Everyone who was struggling to get budget for multi-regional infra failover projects in 2026 just got a lifeline.
