The paper "Is this the simplest (and most surprising) sorting algorithm ever?" introduces the "Sleep Sort" algorithm, a conceptually simple, albeit impractical, sorting method. It relies on spawning a separate thread for each element to be sorted. Each thread sleeps for a duration proportional to the element's value and then outputs the element. Thus, smaller elements are outputted first, resulting in a sorted sequence. While intriguing in its simplicity, Sleep Sort's correctness depends on precise timing and suffers from significant limitations, including poor performance for large datasets, inability to handle negative or duplicate values directly, and reliance on system-specific thread scheduling. Its main contribution is as a thought-provoking curiosity rather than a practical sorting algorithm.

A few users note its potential educational value for understanding sorting network concepts.
Paul Graham argues that the primary way people get rich now is by creating wealth, specifically through starting or joining early-stage startups. This contrasts with older models of wealth acquisition like inheritance or rent-seeking. Building a successful company, particularly in technology, allows founders and early employees to own equity that appreciates significantly as the company grows. This wealth creation is driven by building things people want, leveraging technology for scale, and operating within a relatively open market where new companies can compete with established ones. This model is distinct from merely getting a high-paying job, which provides a good income but rarely leads to substantial wealth creation in the same way equity ownership can.
Hacker News users discussed Paul Graham's essay on contemporary wealth creation, largely agreeing with his premise that starting a startup is the most likely path to significant riches. Some commenters pointed out nuances, like the importance of equity versus salary, and the role of luck and timing.

A few challenged Graham's focus on tech, suggesting alternative routes like real estate or skilled trades, albeit with potentially lower ceilings. The thread also explored the tension between pursuing wealth and other life goals, with some arguing that focusing solely on riches can be counterproductive.
The blog post "Open and Closed Universes" explores the concept of universe curvature and its implications for the universe's ultimate fate. It explains how a "closed" universe, with positive curvature like a sphere, would eventually collapse back on itself in a "Big Crunch," while an "open" universe, with negative curvature like a saddle, would expand indefinitely. A "flat" universe, with zero curvature, represents a critical point between these two scenarios, also expanding forever but at a decelerating rate. The post uses the analogy of a ball thrown upwards to illustrate these concepts, where the ball's trajectory depends on its initial velocity relative to escape velocity. It concludes by mentioning the current scientific consensus, based on observations, which favors a flat or very slightly open universe, destined for continuous expansion and eventual heat death.
