@madversity @timesofindia Agree. But if you quietly remove ' bustard' from the headline, it catches fire ...
Main content anyways explains the chick details

Absolutely outstanding headline in @timesofindia. The person who verifiably wrote this gets a Rs 500 Amazon gift voucher from me

@o8aqpa @Resorcinolworks stupidest thing I have read today, please tell me this is ragebai

@Resorcinolworks Because they're close to a stock exchange center (DSE). HFTs need to be physically closer to stock exchange centers to minimize latency (which is the whole point of HFTs lol). BLR doesn't have a stock exchange, else they'd all be based in BLR given top math talent in based here.

there is reason most of the HFT’s in India are based in GGN, not BLR
but folks are not ready for conversation.

A long-form interview of David Magerman, a well-known retired RenTech partner. Quite a few nuggets of information. Also opinions on AI.

@arya_amsha How did you arrive at these groups? “Arab” is homogenous enough to be a single group but Indo-Aryan is not??

@lauriewired I think 90 years from now life will be so different that the bell labs ‘jump start’ could be seen as a rounding error.. similar to how we dont think too much about the exact year farming was invented
English

My pick would be the Bell Labs transistor team in the late 1940s.
Of course, they can’t replicate the CPU. However, the idea of printed circuit boards didn’t happen until 1958!
That alone would advance humanity a decade, and there’s not really any technical limitations that prevented humanity from making that earlier.
Analysis of lithium-ion chemistry in the battery (30 years early!) would radically change the grid.
Knowing the of miniaturization of compute itself is possible would hugely advance timelines. I’d argue we’d have Windows 95-era levels of compute in the 1970s.
I’m sure someone can think of a more clever era though. Where would you send it?

@Riazi_Cafe_en 2^3 - 1 = 7
The lamp state histories will represent a 3-bit pattern. 3-bits corresponds to 2^3=8 possible unique patterns. Pigeonhole principle: 7 of the lamps can each be assigned a unique pattern, while the remaining 3 lamps must all share the other remaining pattern.
English

At Roshank’s school, there are 10 lamps installed at the highest point of the ceiling. Each lamp is controlled by a separate switch located in the control room in the basement. The control room has 10 switches, but Roshank does not know which switch corresponds to which lamp.
Roshank is very tired and does not want to go to the control room more than 3 times. In these 3 visits, she may turn some switches on or off, and then return upstairs to observe which lamps are lit. Initially, all the lamps are off.
Question: What is the maximum number of lamp–switch pairs Roshank can determine after at most three trips to the basement?

Math Cafe@Riazi_Cafe_en
We have a 6x13 rectangle. Each time, we can cut it horizontally or vertically and break it into two smaller rectangles with integer edge lengths. We can then repeat the same process with each of the smaller rectangles. We continue on until all of the rectangles are squares. How many cuts do we need to achieve this goal? What if the dimensions of the original rectangle is 9x10

When someone asks you why you use so much math in #trading:
-Linear algebra → Optimize portfolios.
-Complex analysis → Price options via transforms.
-Topology → Detect market microstructure.
-Group theory → Exploit symmetries.
-Calculus → Greeks, compounding.
-Probability → Risk & stochastic models.
-Logic → Trading rules.
-Differential equations → PDE/SDE in pricing.
-Inverse theory → Reconstruct signals.

@miakaweebaree @meatballworld had to scroll too much while looking for this reply
English

@atlanticesque i see no explanation explanation as to why the govt wont ban meat except “nuh uh”..
why conservatives would still want to eat real meat if synthetic gets cheaper is a different question altogether
English

No, the rightist opinion here is wrong, and built on a faulty analysis of technology and society. Conservatives correctly associate technology with societal change, but fail to understand why.
The government didn’t ban cash, for example. Everyone *chose* to start using cards.

The tension here is that both of these arguments are 100% correct

Hey there! That thread actually does a pretty good job summing up the legend of Jim Simons and Renaissance Technologies!
He really did gather brilliant minds, often PhDs from fields like math and physics with no prior finance experience, to crack the market using quantitative models.
Some key hires even came from his earlier work in places like the Institute for Defense Analyses.
His firm, Renaissance Technologies, focused on developing complex mathematical models based on vast amounts of historical data to find subtle, predictive signals in the markets.
The Medallion Fund's performance was legendary!
The often-cited 66% average annual return was *before* fees; the net return to investors was still an astounding 39-40% annually on average, even after Renaissance charged fees much higher than the typical 2% management and 20% performance fees seen elsewhere.
One of the images shared in the thread also shows this 39.9% net figure [Attachment 4].
It's also spot on that they closed the Medallion Fund to outside investors pretty early on, around 1993.
They realized its strategies had a capacity limit, meaning too much money would dilute the edge, so it became an exclusive fund primarily for employees and their families.
Simons was known for fostering a unique environment.
He aimed to assemble a top-tier team, valuing deep thinkers who could solve hard problems.
The goal, as he put it, was a "pure system without humans interfering" with the models.
And yes, a core principle was that human judgment or "gut feelings" were not to override the trading models; all decisions were driven by the quantitative systems.
This systematic approach helped remove emotion from investing.
By the time of his passing, Jim Simons had amassed a fortune of over $30 billion and, with his wife Marilyn, was a major philanthropist, donating billions, particularly to scientific research and education.

@EgissBennet @Rainmaker1973 can you rewrite this in rap lyrics? just testing something
English

The Rhind Mathematical Papyrus is the oldest manuscript written in algebra and trigonometry, dating back to 3,550 years ago.
It shows that the Egyptians used first-order equations, geometric series and a second-order algebraic equation, related to the Pythagorean theorem a² + b² = c²
It also describes how to obtain an approximation of π accurate to within less than 1% and one of the earliest attempts at squaring the circle.
