The article discusses the relevance of Nagle's algorithm, introduced in RFC 896 in 1984, in the context of modern distributed systems. The author highlights that enabling the TCP_NODELAY socket option can often resolve latency issues caused by small packet transmissions, which Nagle aimed to optimize. Nagle's algorithm was designed to reduce the overhead associated with sending numerous small packets by preventing the transmission of new TCP segments until previously sent data is acknowledged, thereby improving throughput. However, it can interact poorly with

HistoSonics has developed the Edison system, which utilizes a water-filled membrane to deliver focused ultrasound for treating pancreatic cancer. This system exploits cavitation—the formation and collapse of tiny gas bubbles—causing mechanical stress that destroys cancer cells and liquefies tumors. Initially viewed as a harmful side effect, cavitation was studied by researchers at the University of Michigan starting in 2001, leading to breakthroughs in harnessing it for medical purposes. Zhen Xu, then a Ph.D. student,

In high-scale distributed systems, even a slight increase in latency in a leaf service can lead to cascading failures, where localized performance degradation escalates into complete site outages. A core issue in microservices architectures is the use of synchronous, blocking I/O within fixed thread pools. When a downstream service experiences significant latency, it blocks the worker threads in the calling service, leading to resource exhaustion. For instance, an API gateway with 200 worker threads can quickly become saturated if it waits on a slow downstream service

Generating crossword puzzles is an NP-Complete problem due to the constraints that intersecting words create across the grid. As a result, there is no efficient algorithm that guarantees a solution, but effective heuristics can produce satisfactory outcomes. In late 2021, the author, inspired by a passion for the New York Times Crossword during lockdown, embarked on a project to create a crossword app. This led to the development of "Crosswarped," an iOS and Android game utilizing an algorithm for generating cross

The essay "When 2 + 2 Does Not Equal 4.0" explores the concept of equality in programming languages, highlighting the distinction between functional equality and semantic equality. It begins by discussing how incorrect assumptions about equality can lead to unexpected behaviors, as illustrated by JavaScript's treatment of different values like "" and [0], which are equal to 0 but not to each other. The essay references Leibniz’s Law, which posits that two things are identical if they share
