Explorations and deep dives across science, technology, finance, investing, economics, and photography.
Design patterns offer proven, language-agnostic blueprints for solving recurring software engineering challenges. While the underlying architectural principles remain universal, their concrete implementations vary meaningfully depending on each language’s type system, memory model, and native...
To the average retail investor, dividends seem straightforward: you own a stock or an ETF, and every few months, cash appears in your brokerage account like magic. It is often celebrated as “passive income”...
In modern global finance, few strategies are as deceptively simple—or as systemically perilous—as the Yen Carry Trade. For decades, it has served as the silent financial engine powering global asset prices, funneling trillions of...
If the universe operated strictly according to the rules of classical Newtonian mechanics, our world would look radically different: the Sun would never have ignited, stars would not shine, and heavy radioactive elements would...
The Repurchase Agreement (Repo) market is often described as the “plumbing” of the global financial system. While it rarely makes headlines during normal times, trillions of dollars flow through it every single day. Without...
Every now and then I encounter algorithms that is both intuitive as well as far-reaching. The algorithm to be described in this post is called Cartesian Matching Algorithm. Bear with me here, as this...
I like seeing elegant algorithms arise out of prodigious mathematical methods. One such is calculating day of any date in O(1). Let’s take a look at the implementation. int getDay(std::vector<int> date){ int m=date[0], d=date[1],...
One of the remarkable features of Modern C++ is variadic templates. Ability of templates to take variable number of was initially designed by Douglas Gregor and Jaakko Järvi and then standardized in Modern C++....
Median is considered one of the important measures in Statistics. Unlike Mean, it is not skewed by a few very large values in the dataset. Computing Median can seem like a trivial problem and...
I recently had a chance to watch an interesting CppCon lecture by Arthur O’Dwyer titled Back To Basics: Smart Pointers. Atleast for me, the talk was a pretty good review/refresher of what Smart Pointers...
Quack is an unique data structure that combines the properties of both Stack and a Queue. The structure can be viewed as a list of items written from left to right. It lets you...
