America's Protein Obsession: What's Driving It---and How to Navigate It Safely

In the United States, protein isn't just a macronutrient---it's a cultural symbol. Whether it's emblazoned on snack bars at the checkout line or fueling Instagram influencers' morning routines, protein has become the star of the nutritional show. But what's behind this fixation, and how should health-conscious individuals navigate it?

How Protein Became a Cultural Icon

Protein has long been associated with strength and vitality, but in recent decades, that connection has evolved into a full-blown obsession. Starting with the bodybuilding boom of the 1970s and later amplified by the low-carb craze of the 1990s and 2000s, protein earned a reputation as the "clean" nutrient---unlike fats, which were demonized, or carbs, which still struggle under the shadow of dietary suspicion.

Today, the narrative goes beyond physical health. A high-protein, mea

Kawaii: a dumb little JSX front-end library, purely created for educational purposes

I wrote this to teach myself on how React and other JSX library work behind the scenes.

Usage

First, you will need a bundler that doesn't exclusively work with React. Unfortunately, how to configure it is beyond the scope of this README file, since every bundler has their own way of converting JSX to JavaSript.

That said, there are some tutorials on how to do that.

Bounded Variable

Think of a bounded variable no different than a bounded queue to solve the consumer—producer problem.

A very common use case is for me is to push to a single variable from one producer, and pull from that single variable from one consumer.

Go has a very simple solution: channels.

But I was curious: can we improve the performance?

We want to prove that

$$ \left(1+\dfrac{1}{n}\right)^n < e < \left(1+\dfrac{1}{n}\right)^{n+1} $$

We will assume that $n \in \mathbb{N}$, $n &gt; 0$.
