Programming languages have widely varying ability to communicate logic succinctly.

If you look at character counts of 10 basic programs in each, Java has 2x higher entropy than Python.

Very different result for natural spoken languages. Heres a sample of 5 algorithms that were compared and their respective character counts.

Height in China has exploded faster than any country in history at 1.75cm/decade!

Studies show the average male height over the last ~50yrs went from 5'6" to 5'9", leaving only Lebanon, Russia and Turkey are higher in Asia.

This is proof of how economy affects genetics.

1/4 Causes of growth:
— Socioeconomic improvements
— One-child policy may have led to concentration of resources
— Increased protein and dairy consumption.

The 2.5cm/decade growth in the 70s far outdoes the 1cm/decade the west saw in the 1870-1970 period!

Compilers was was known to be the hardest CS class at Cornell which was hard as it is.

We were handed a 8-page PDF at the start of sem for a language spec we'd be implementing by the end of sem, split into 6 parts.

On part 5, the median was a 0/100 and most the class failed. For those curious, here's the rest of the spec. Part 1:

BREAKING: One of India's most massive hacks is happening right now!

~31M rows of Star Health Insurance data — name, DOB, address, phone, PAN card and salary for Indians is selling it for $150k.

Hacker claims CISO Amarjeet Khurana sold him the data.

Nothing is private in India. You can buy and see a sample of the data here: starhealthleak.st

Nobel Physics Prize winner Geoff Hinton's middle name is Everest.

It comes from his great-great-granduncle Sir George Everest, once British surveyor-general of India, after whom Mount Everest was named.

Talk about lofty family expectations. His lineage is full of shockers.

His great-great-grandfather? George Boole, the namesake of "boolean" that is essential to computers and the Information Age.

Indian startup Dotpe, that raised ~$100M to build point of sale systems for restaurants left their entire API fully public.

A clever hacker found out the most ordered thing at every Social in India.

And did a prank to order what he wanted for a person next to him!

I want to dispel certain accusations made about my EB-1 blog on X.

I wrote that to help people. To not gate-keep knowledge. It's not great to be punished for that. The primary reason I write online is to help.

I'll break down the claims and why they're patently false:

1/8 On low quality science journals.

1 I did not use them, you can check Scholar.
2 These were recommended in the onboarding email of one of the biggest immi law firms that I used at first who have done 1000s of EB-1s.

I don't recommend it, but people have the right to know.

My GREEN CARD just came in the mail today! 🇺🇸

I've spent the past 13yrs in the US afraid of being fired, anxious about travel paperwork, and not knowing if I'd spend New Years with family. Takes 100+yrs for India-borns unless you do an EB-1A.

Things immigrants go through:

1/8 You can't study what you want.

A close friend, a star mechanical engineer, learnt by soph year that most of the jobs he wanted didn't hire intls — Lockheed, Boeing, SpaceX. At his lowest point, he almost switched to CS. He ended up powering through a top PhD to get a job.

When I write about leaving India, many say I'm biased. Let's look at data.

Every year, ~2.5M Indians move abroad.

Indians are the largest overseas diaspora with 30M+ people. In comparison, ~30M in India make 10LPA ($12k/yr). People who leave far outnumber those who return!

1/7 The topic of moving to and from India is so prone to narrative building on both sides..

Indians overseas feel patriotic and say "I want to move back" without doing so. Indians in India for 30yrs have said "India's future is now, why leave?" and cherrypick flaws abroad.

Redditor goes from failing their college Algorithms and Data Structures class to cramming Leetcode for months and getting an E5 offer at Meta.

If the system is this broken, you might as well exploit it and take home $500k/yr.

Common myths:
"They're not hiring anymore"
"They don't ask leetcode questions anymore, maybe others but not us"
"Leetcode won't work, you need my course"

90% of teams espp at FAANG don't care about your experience, just interview scores. Hardest part is getting an interview.

Claude Artifacts allow you to go from English to an entire app, and share it!

A PM friend of mine who couldn't code now creates apps in minutes. The cost of a lot of software is nearing ~0.

Here are the best Artifacts I found on the internet (include a Rubik's cube sim) —

What are the top 10 ranks from IITJEE, the hardest exam in India, 1987 doing today?

1M compete for 10k slots in engineering at IIT. People believe a top rank is a made life. Is it, 37 years on?

4 Profs, 2 founders, 2 financiers, 2 tech and 4 in India and 1 big on X!

🧵

1/13 Rank 1 — Rajesh Gopakumar

One of the best string theorists.
— From Calcutta, did Physics at IITK, not CS
— Princeton PhD, research at Harvard
— Moved back to India to be a Prof at TIFR in Bangalore
— Fun fact: ICTS was funded in large part by Jim Simons of RenTech

Hack to tell if an image is AI-generated: bump up the saturation and look at the microphone patches and teeth.

What are the top 10 ranks from IITJEE, the hardest exam in India, 1986 doing today?

Tons of professors in the US, founders and 2 IAS officers!

Rank 1 — Sanjeev Arora
Princeton CS professor, 2x Godel Prize winner and overall legend. Didn't finish IITK, transferred to MIT

1/11 Rank 3 — Manoj Govil

Information on him is scant, but all I could find is that he has a PhD in Corporate Affairs from Princeton before going into IAS — an elite wing of the Indian government which requires an equally competitive examination, the UPSC.

I built this open-source app to write outbound emails for hiring, fundraising or selling a product using a LinkedIn link and a company URL and Claude.

Best part? Claude built it all in 30mins!

Everyone not building with AI will be left behind.

Step-by-step guide 🧵

1/8 Prompt 1. I fed it the Anthropic API docs raw, and I described what I wanted to build.

Prompt 2. I asked "how do I build this locally on my Mac"

What are the top 10 ranks from IITJEE, the hardest exam in India, 2009 doing today?

The craziest thing is India won 4 International Physics Olympiad Golds, and all 4 were in the top 6!

IPhO Gold, IIT Delhi, Twitter, Google SWE. 1 of 2 who is in India.

1/11 Rank 2 — Shubham Tulsiani

Also IPhO Gold.
— PhD from UC Berkeley

What are the top 10 ranks from IITJEE 1992 doing today?

The IIT exam is the hardest exam in India — 1M students compete for 10k slots in engineering. People believe a top rank is a made life.

List includes a billionaire, 2 who went to MIT & Caltech, and one woman!

🧵

1/12 Rank 1 — Anil Kumar Ruia

Went to Princeton and maybe transferred to Rutgers and then spent most of his life at Microsoft where he's a very senior engineering manager.

The IMO is the hardest high school Math test. A lesser known sibling, the IOL (International Olympiad for Linguistics), starts tomorrow!

Students are asked to translate lesser-known languages purely using logic. 5 problems, 6hrs.

The problems seem absolutely impossible. And if that wasn't hard enough, they also have a 3-4hr team challenge!

This entire idea of the self-sufficient linguistics problem originated in the 1960s by Russian linguistics at Moscow State University.

HUGE Immigration News for International Entrepreneurs!!

If you own 10%+ of a US startup entity founded <5yrs ago with $264k+ of funding, you+spouses of up to 3 co-founders can come work in the US for 2.5yrs with renewal to 5yrs.

Startups globally can now come build in SF!

1/5 A "qualified investor" has to be a US citizen or PR who has made $600-650k in prior investments with 2+ startups creating 5+ jobs or generating $530k revenue growing 20% YoY.

If you don't meet the funding requirement, don't lose hope. You CAN provide alternate evidence.

A theory of why Claude 3.5 Sonnet is insane at coding: mechanistic interpretability.

Anthropic showed that there are clever ways to understand what the weights of LLMs do and "steer" them to behave differently.

Doing this on Sonnet may be why it crushes it at code:

🧵

1/12 When you try to understand each weight of a model on their own, they don't make sense.

This is superposition: each neuron represents many features, but combinations of them may represent a single "feature" that we can make sense of.
