Today is the 106th death anniversary of the amazing genius, Srinivasa Ramanujan. Ramanujan passed away at a young age of 32 on April 26, 1920, at Kumbakonam in Tamil Nadu. Hardy compared #Ramanujan with mathematical geniuses such as Euler and Jacobi. Thread I had compiled in 2020: x.com/aparanjape/sta…



Vasiṣṭhas(sons of Vasiṣṭha) were fair in complexion (śvityañcaḥ) and wore a right-sided hair knot(tuft),(dakṣiṇatas -kapardā). -Ṛgveda 7.33.1



There is 0 recognition of Ramanujan in TN because reasons...

@Deshpacito661 Do u even know that it goes close to 0 degrees C in winters in Florida? India heat + humidity thru summer + monsoon months is exceptional

Open letter to Indians in America. -- Dear brothers and sisters from Bharat: Like I did 37 years ago, you arrived in America with no money but with a good education and cultural heritage from Bharat. You achieved outstanding success. America was good to us. For that we must remain grateful - gratitude is our Bharatiya way. Yet today, a significant number of Americans, may be not the majority but not too far from it either, believe that Indians "take away" American jobs and our success in America was unfairly earned. You may think the next election will fix this, but your choice would be between people who hate our Bharatiya civilisation and people who hate civilisation itself. That is the "hard right" vs "woke left" battle. You are mere bystanders to that conflict. Meanwhile there is one thing that is true now and will be true in the future: the respect Indians command world-wide will substantially depend on the fortunes of India herself. If India remains poor, the woke left will give us moral lectures with pity and the hard right, different moral lectures with scorn ("hellhole") and we must not confuse either with respect. Respect in today's world, along with prosperity and security, comes from one source: a nation's technological prowess. India produces sufficient brain power to achieve that prowess but alas we exported so much of that talent, particularly to America. As we develop that prowess in India, our civilisational strength will assert itself. As difficult as it is for many of you to contemplate this, please come back home. Bharat Mata needs your talent. Our vast youthful population needs the technology leadership you gained over the years to guide them towards prosperity. Let's do it with a missionary zeal. Respectfully Sridhar Vembu

@AgentSaffron i think H have been squeezed to the last drop. so those who were let go to nix future competition from 80s through 2010s ar being called back quite devious

Jane Street made ~$40B in 2025 with 3,500 employees, a ~2x from the year before. At ~65-70% profit margin, that's $8M profit / employee, the highest for a 1000+ ppl company. High-frequency trading continues to be the most efficient money making engine. I want to share an old story about my Jane Street interview in 2014. Jane Street was known for hiring a lot of math, physics and CS olympiad winners from top universities and putting them through many rounds - including, for trading roles, a gauntlet of mental math. It was my 6th interview and my final round and I recall being asked "What is the next day after today in DD/MM/YYYY where all the digits are unique?" They'd toy with you and say "You can use a pencil and paper, if you want" but you knew that was an instant no. Painstakingly and as quickly as I could, I came to an answer. "How confident are you that this is correct on a 0-1 probability scale?" the interviewer said. "0.95", I blurted out, not fully knowing how to answer that. "Are you sure?" After thinking harder for a few more seconds, I realized I could've flipped the digits around to get a closer date. I gave the interviewer my answer. It was correct. "0.95 huh?" he chuckled. That's when I knew I failed. Note: fwiw, other companies that come close in efficiency are - Tether ($90M+ profit/emp) - Hyperliquid ($80M+ profit/emp) and on revenue: - Valve ($50M/emp) - OnlyFans ($37M/emp) - Craigslist ($14M/emp) - Anthropic ($12M/emp, run rate) - OpenAI ($8M/emp, run rate) For comparison, Nvidia is very efficient at scale and is $4.4M/emp.


It’s sad how so many Germany-Jewish veterans were betrayed by their country. German Jews volunteered at very high rates in WWI. It was a Jewish lieutenant who actually recommended Adolf Hitler for the Iron Cross - Hugo Gutmann
