I have now re-examined this document:

November is here, and that means a massive shift is coming. And by "massive" I am of course referring to the redefinition of the kilogram unit of mass that the world has been building up to for more than 100 years. Let me explain:

1/ I've had an unhealthy fascination with metrology (the study of measurement) ever since my 2nd year as a physics major when I took a class devoted to duplicating historic physics experiments, so please indulge me for going into heavy detail (get it?) about the kilogram.

2/ So what actually *defines* a unit of measurement? If you're American, you probably know a mile is 5280 feet and a foot is 12 inches and an inch is 2.54 centimeters etc. But where does this chain of definitions end? Is it turtles all the way down?

3/ It's actually not! For all units (even the imperial units used in America) the answers all end with the Système International (SI) unit definitions established and maintained for over 100 years by the Bureau International des Poids et Mesures (BIMP) in France.

4/ At the base of this tower are the SI base units. Just 7 SI base units define every other unit in existence. They are:

Kilogram, kg (mass)
Meter, m (distance)
Second, s (time)
Kelvin, K (temp)
Ampere, A (electric current)
Candela, cd (luminous intensity)
Mole, mol (quantity)

THE BATTLE OF SARAIGHAT (1671)

Lachit Borphukan's humiliation of Aurangzeb.

The battle of Saraighat was a naval engagement fought on the Brahmaputra river near Saraighat between the M0ghul empire and Ahom kingdom in 1671.

Guts, resolve and glory!

(Elaborate thread)

Koch was a state situated between the dominions of M0ghuls and Ahoms. For Ahoms, it was a buffer state for keeping M0ghul territorial expansions at bay.(1)

Times changed when the ruler of the Koch kingdom, Nara Narayana passed away in 1587 resulting in Koch being divided into 2. Western Koch was ruled by his son Lakshmi Narayan and the eastern Koch by his nephew, Raghudev.(2)

Lakshmi Narayan formed an alliance with M0ghuls after which he attacked Parikshit, son of Raghudev, in 1602. Parikshit Narayan was defeated while his brother Bali Narayan took refuge in the Ahom Kingdom.(3)

The M0ghuls used it as a pretext to invade Ahom kingdom. The first battle between them took place in 1615 leading to a series of engagements in which both sides had their shares of ups and downs resulting in a stalemate.(4)

Published a new essay: The red flags and magic numbers that investors look for in your startup’s metrics – 80 slide deck included!

This was a deck that I created on my (longish) interview process with @a16z. It was a long path, starting with meeting folks at the firm 10 years ago. But the purpose of the deck was to explain how I would use my superpower in an investing context

Here's what I explain in the deck. As investors (whether angel or VC) we're often confronted with an up-and-to-the-right graph. Is it going to go up? Or down?

One solution to forecast these growth curves is the Growth Accounting Framework, where you add up New+Reactivated and subtract churned users. In each time period that gives you the difference in monthly actives.

The problem with this is that it's a lagging metric, not a leading one. We need to go one level deeper and look at the underlying loops that drive these numbers, to understand the quality.

How to Get Rich (without getting lucky):

Seek wealth, not money or status. Wealth is having assets that earn while you sleep. Money is how we transfer time and wealth. Status is your place in the social hierarchy.

Understand that ethical wealth creation is possible. If you secretly despise wealth, it will elude you.

Ignore people playing status games. They gain status by attacking people playing wealth creation games.

You’re not going to get rich renting out your time. You must own equity - a piece of a business - to gain your financial freedom.
