Observation - Living a low key life helps with mental peace!

[Aakash Gupta @aakashgupta]

There's a physicist at Stanford named Safi Bahcall who modeled this exact principle and the math is wild.

He calls it "phase transitions in human networks." When you're stationary, your probability of a lucky event is limited to your existing surface area: the people you already know, the places you already go, the ideas you've already been exposed to. Your opportunity window is fixed.

When you move, your collision rate with new nodes in a network increases nonlinearly. Double your movement (new conversations, new cities, new projects) and your probability of a serendipitous encounter doesn't double. It roughly quadruples. Because each new node connects you to their entire network, not just to them.

Richard Wiseman ran a 10-year study at the University of Hertfordshire tracking self-described "lucky" and "unlucky" people. The single biggest differentiator wasn't IQ, education, or family money. Lucky people scored significantly higher on one trait: openness to experience. They talked to strangers more, varied their routines more, and said yes to invitations at nearly twice the rate.

The "unlucky" group followed the same routes, ate at the same restaurants, and talked to the same 5 people. Their networks were closed loops. No new inputs, no new collisions.

Luck isn't random. Luck is surface area. And surface area is a function of movement.

The lobster emoji is doing more work than most people realize. Lobsters grow by shedding their shell when it gets too tight. The growth requires a period of total vulnerability. No protection, no armor, soft body exposed to the ocean.

That's the cost of movement nobody posts about. You have to be uncomfortable first. The new shell only hardens after you've already moved.

Been working on this for 2 months, and it's finally ready to share!

This piece not only *describes* how B-trees and database indexes work, but gives you the opportunity to interact with them, reinforcing the concepts, and providing a bit of fun along the way.

@TataMotors @TataCompanies, why is Tata Service Center in Pune not accepting any other payment method apart from UPI. They forced me to pay via UPI, but later got a link saying pay online on this link which accepted other payment methods.

@TataMotors @RNTata2000 @TataCompanies, why are you sharing my number and details everywhere?

I've been getting calls from Insurance providers for about a year now.

I've never shared consent to share details elsewhere while purchasing a vehicle

OpenAI just acquired Rockset to power RAG.

Rockset was founded in 2016 by an ex-Facebook team that built RocksDB, a fork of Google's LevelDB, an embeddable NoSQL DB written by Jeff Dean himself.

Over time, the 100 person co built hybrid search - vector (FAISS) and keyword.

Hear me out - If you are in big data, you should pay attention to rust lang if not Cpp along with whatever language you are using.

This is not a mere hypothesis anymore, apache has several rust projects and they are gaining popularity fast.

Here are some projects -
- Datafusion
- Datafusion Comet
- Arrow Flight
- DuckDB (cpp)

Big data was dominated by JVM for more than a decade and to be honest it did well.

However, the 'composable data stack' has decided to go towards Rust, I think.

Thoughts?

advice from OG industry veteran:

While working on large-scale projects, small PR check-ins are more valuable and right way to move ahead because, in future, people will refer a PR and it would become extremely difficult to answer the whys with other changes

@rshakoor12 Pure torture debugging deadlocks in Rust. You can only add 100s of debug logs and go through 1000s of lines as it's very difficult to get thread dumps / debug with gdb
