@Haseeb9Bukhari @prakdadlani India will be growing no matter what. I hope Pakistan does too because countries that focus on growth and development don't have time to think of cross border terrorism.

@ProfKiRaquel @prakdadlani @SaffronAgni Rahul Gandhi should be thanked as well 😂

@Nihar_t2 @AskAnshul Switzerland is not part of the EU. Also, they are historically known to be neutral on world issues. That's why their findings/reports are trusted.

@E__Strobel @AlexFinn Could you share the list?

[Sahil Mehra @ThisIsSMehra]

@amuldotexe @bryan_johnson Jains who have a protein rich diet have it all figured out

@lalopenguin @marclou @grok Love San Diego but California is expensive af.

[Sahil Mehra @ThisIsSMehra]

@abhjeet141 @marclou @grok Lol he said ocean, tax friendly and clean air. Jaipur isn't even considered a tech hub in India.

4/4 Kornia isn't just a library - it's a layer in your neural network.
I can't believe I didn't know this existed. Game changer!

Stop using OpenCV in your Deep Learning pipelines. 🛑

Most engineers treat vision like a "black box" - once the image is processed, the math stops.

But with Kornia, the math is just getting started.

Here is why Kornia is the "OpenCV for PyTorch"🧵👇

3/4 Learnable Filters vs. Static Tools 🛠️
Imagine a camera in changing light
• OpenCV: You hard-code a threshold and hope it works.
• Kornia: The threshold becomes a "learnable parameter."

The system "squints" or "adjusts" its own filters in milliseconds to see through glare

San Diego is like that Indian kid who is asked to show their talent to guests at home.
Sunny and beautiful 300 days of the year but when someone comes to visit from far away:

@BharukaShraddha Totally agree. I've learnt it the hard way, trying to bring myself out of tutorial hell. Took some time but helped so much in the long run.
I have made it a point to only learn by building now.
Currently, building PyTorch from scratch to learn C++ and brush up on ML basics.

[Sahil Mehra @ThisIsSMehra]

@Hesamation Thanks for the inspiration that I needed! Building pytorch from scratch in C++ and will be posting about the performance comparisons with PyTorch. Do you know of any use cases (embedded systems?) where a slightly different framework is needed? Want it to be useful, if possible.

[Sahil Mehra @ThisIsSMehra]

Is there a need for pytorch like library but for embedded systems with hardware constraints?

[Sahil Mehra @ThisIsSMehra]

I want to build PyTorch from scratch (mainly, for learning purposes). I don't just want it to be a worse clone of something that is already pretty good. What can be a good twist/use case that I can build this for so that it is actually useful? I'll be building in C++ of, course.

Major life trap: Getting your dopamine from information gathering. Dopamine from information is a dangerous drug. Your entire life will change the moment you stop looking for more information and start acting on the information you already have. Get your dopamine from action.

@HiBro443883 This is great analysis. I don't think there is any record of which pitch was used on that day. Why not use the furthest pitch from that spot on the roof to eliminate any doubt?

ATS deserves more credit. They are unsung heroes.

[THE SKIN DOCTOR @theskindoctor13]

Ricin is one of the deadliest poisons known. Tasteless, odourless, you wouldn’t even realise if it was mixed into your food or water.

Meet Dr. Ahmed Mohiuddin Syed, an MBBS from China. Using his medical knowledge, he had been extracting ricin from castor seeds for a long time to carry out what would have been one of the biggest mass poisonings in the world by mixing it in water and likely temple prasad in Delhi, Ahmedabad, and Lucknow.

He, along with two others, Mohd. Suhel and Azad, was arrested by the Gujarat ATS. They were in contact with ISIS handlers through Telegram. They were also in contact with Pakistani handlers who were dropping weapons for them through drones.

Another reminder that we don’t thank our anti-terror agencies enough. Their job is like that of a goalkeeper: you are noticed not for how many goals you save, but only for the ones you fail to stop. We will never know how many terror plots our agencies have foiled in the last decade. It must be many. There are so many radicals who want to harm us all the time, and yet we’ve seen mostly peace in civilian areas over the past decade. Hats off, and gratitude.
