Our Nattu is back and he’s stronger than ever 💙❤️

@siddharth_iitm @paraschopra The cupboard of requirement

@paraschopra Interesting! We have an everything-cupboard for this, where you can find... yes, everything! 😄

Steal this idea. A dark store which stocks your own rarely-used household objects. You ship those occasionally-used but space occupying things and simply get them back within 10 mins from an app, whenever you need them. A minimalist’s dream service :)

WELCOME BACK, NATTU…!!! 🫡 - 3/29 at the Ekana in the opening match of Delhi Capitals in IPL 2026. Great to see Nattu in form, he’s bowled a great spell. ✅

Other team players leaving team bus Vs New Zealand players leaving team bus, The difference is very clear 🫡❤️

So, my first ever manager at my current org got promoted to the CTO at the sister company. I'm really happy for the man, you know. He comes from a C# background, but he learnt about how things work on the electronics side of things, understood how Linux and embedded linux works, and made significant contributions to the product. He helped me a LOT when I first came in, and he worked unnecessarily hard for the product. He switched from simple software engineering to Embedded product development when he was well in his 30s, you know. Just goes to show you that, well, you can just do things you see. I'm sharing this as a success story for anyone who's willing to come to the hardware side of things - it is possible, and can very much be done !

Everyone stop scrolling: there is a team of undergrads in IIT Bombay building a semiconductor fab. Their goal is not to build commercially valuable products on day 1, but rather to build a culture of learning, growth, and innovation. Engineers studying semiconductors don't get to even touch a wafer today until they are doing post-grad work or they join industry. For a country that wants to be become self-reliant in the critical domain of semis, this is a travesty. We need our students to gain exposure and begin working with real tools and materials as soon as possible. This is what HackerFab is doing. They built their own light source by repurposing a commercial projector. They made plasma and RF sputters for metal deposition. They sent first years into the Mumbai street markets to procure sheet metal and make their own tube furnace. In the process, they learned so much about each individual tool and process in the supply chain. They even learned how to navigate the real world of vendors, suppliers, and logistics. But most crucially - they set a standard. The entire team at HackerFab is full of energy, agency, and ambition. They trust each other to get shit done, and they all push themselves to learn more than they ever thought they could. In just a few months, they can already produce chips with feature sizes of one micron. I have no doubt they will make better tools, processes, and transistors as they move forward. The best part of this is that they have already inspired other colleges to take up the journey - they are sharing their learnings and techniques so that students and hobbyists around the country can begin working with semis. I'm sure it won't be long before the ethos and capabilities sparked by HackerFab spring up across the country. This is they have my utmost respect, and they deserve support from the whole community. If you ever want to have the most inspiring, white-pilling day - just visit HackerFab at IIT B! Thank you @aryamman_bhatia, @shaashvats30, @jaibellare, and team @hackerfabindia!

I respect that the leaked source code for the @claudeai client is protected by copyright. But wouldn’t it be ok for me to train my LLM on it? You know, fair use and all that. Asking for a friend.

<Something serious> Workers in factories are not able to afford black market cylinders. Cylinder bookings are getting cancelled. If this is not solved, we are looking at emergency migration of workers back to villages.

Some of my favorite ones: • Shubhcron → github.com/razorpay/shubh… • RQuery → github.com/razorpay/rquery • CryptoCows → github.com/razorpay/crypt…

For years, @RazorpayTech did April Fool’s launches mostly as an inside joke. This year, we couldn’t 😔 Nothing we came up with was crazier than what we’re already building.

The research behind this is wild. If you played Pokémon as a kid, you have a tiny region in your brain that exists only because of Pokémon. Not a metaphor. Stanford put people in brain scanners and found it. The study was published in Nature Human Behavior in 2019. They scanned 11 adults who grew up glued to their Game Boys and 11 who never played. When they showed both groups images of the original 151, the players' brains lit up in one specific spot every time. Same spot across all 11 people. The non-players showed zero response. That spot is a little fold in the back of your brain that normally processes things like animal shapes and cartoon faces. In the Pokémon players, a chunk of it had been permanently reassigned. Their brains carved out a Pokémon department sometime around age 6 or 7 and just never took it down. And the reason it ended up in the same place in everyone's brain comes down to the Game Boy itself. The screen was 2.6 inches. Every kid held it at roughly the same distance. So those 151 characters hit the exact same patch of each kid's retina, thousands of times, during the years when the brain is still soft enough to reorganize itself. Where an image hits your retina in childhood is what tells your brain where to build the wiring. Reading works the same way. Humans invented writing about 5,000 years ago. There's zero evolutionary reason for a brain region dedicated to recognizing words. But every person who learns to read grows one, roughly the size of a dime, in the same part of the brain. Brain-imaging research from 2018 actually watched it appear in children's heads as they learned their letters. It grew by quietly taking over nearby tissue that wasn't doing much yet. Stanford published a follow-up this year showing this region is way smaller or missing entirely in kids with dyslexia, and that 8 weeks of intense reading practice physically grew it back. London taxi drivers show the same thing in a completely different part of the brain. Brain scans from a 2000 study found the region that stores mental maps had physically expanded, and the longer they'd been driving, the bigger it got. These drivers spend 3 to 4 years memorizing 25,000 streets before they get licensed. About half wash out. The common thread is childhood. Harvard researchers trained young monkeys to recognize new shapes and they developed brand-new brain regions in predictable locations. Adult monkeys trained on the same shapes never got those structural changes. The young brain wires itself in a way the adult brain cannot replicate. If you're wondering whether a Pokémon patch in your brain means you lost something else, no. The region sits alongside your normal visual processing areas, not on top of them. Your brain has hundreds of millions of neurons in that zone alone. The lead author noted that every participant in the study had gone on to earn a PhD.

FFmpeg is moving to Rust 🦀 Our use of C and Assembly in FFmpeg has been an unacceptable violation of safety. FFmpeg will be running 10x slower - but we're doing it for your safety. All your videos will appear green - safety first, working software later.

What an end to the financial year 😀😀 Upgraded to saying “do bachhon ka baap hu yaar” Both mother and baby doing well. Grateful 🙏🏻🙏🏻

- Drafted a blog post - Used an LLM to meticulously improve the argument over 4 hours. - Wow, feeling great, it’s so convincing! - Fun idea let’s ask it to argue the opposite. - LLM demolishes the entire argument and convinces me that the opposite is in fact true. - lol The LLMs may elicit an opinion when asked but are extremely competent in arguing almost any direction. This is actually super useful as a tool for forming your own opinions, just make sure to ask different directions and be careful with the sycophancy.

Dps, tank, utility, healer

Didn’t expect these to reach that high number
