The article discusses the phenomenon of "zombie" companies that continue operating despite being financially insolvent. It examines how these companies persist through various economic mechanisms and government support programs.

The article describes a weekend project called the Chicken Squisher 3000, which appears to be a humorous or experimental device related to poultry. The author references the saying "If it clucks like a duck..." suggesting a playful approach to identifying or interacting with chickens.

The article explores various practical applications of diodes, highlighting their versatility beyond basic rectification. It covers uses in signal mixing, voltage regulation, and circuit protection, demonstrating how this fundamental component enables numerous electronic functions.

The article examines Euler's identity, tracing its origins to a 1748 formula by Leonhard Euler. It explores the mathematical context and significance of this fundamental relationship between exponential functions and trigonometric functions.

The author, a middling writer, states they can easily detect LLM-generated articles. This suggests AI writing has become sophisticated enough to pass as human-authored content in many cases.

The article discusses the technical challenges involved in building a functional oscillator circuit. It explains why creating a reliable oscillator is more difficult than it might initially appear.

The article discusses a circuit known as a charge pump voltage halver, which appears deceptively simple but operates in a counterintuitive manner. It explains how this seemingly basic circuit can halve voltage through clever switching and capacitor charging.

The article discusses switched capacitor lowpass filters as an alternative to traditional resistor-based designs. It explores how these circuits work and their advantages in modern electronics applications.

The article explains operational amplifier (op-amp) arithmetic circuits in an accessible manner, covering how these electronic components can perform mathematical operations like addition, subtraction, and integration through their circuit configurations.

The article discusses phase-locked loop (PLL) frequency multipliers, which can transform a 1 MHz input signal into a 100 MHz output through frequency multiplication techniques.

The blog continues its tradition of addressing unconventional questions that most people wouldn't think to ask.

The article discusses the value and effort involved in creating blog art, noting that images can have significant monetary worth despite the labor required to produce them.

The article examines the tesseract, a four-dimensional hypercube, and explores various methods for rendering it on a two-dimensional screen. It discusses the mathematical concepts and visualization techniques involved in representing higher-dimensional geometry.

The article discusses the design of a subtly deceptive blur filter and then examines its vulnerabilities and limitations. It explores how such filters can be manipulated or broken through various techniques.

The article discusses the peculiar nature of real numbers, highlighting their counterintuitive properties and mathematical oddities that challenge conventional understanding of numerical systems.

The article discusses mathematical concepts including the approximation 22/7 for pi and the pigeonhole principle attributed to mathematician Peter Gustav Lejeune Dirichlet.

The author examines the prevalence of AI-generated content on Hacker News, noting the platform's dual role as a major traffic source and a site with toxic commenters. The analysis explores how much of the discussion may be driven by artificial intelligence rather than human users.

The article describes a physical implementation of Conway's Game of Life using mechanical switches and relays. It explores how this classic cellular automaton can be built with real-world components rather than computer simulation. The implementation demonstrates the principles of the game through physical hardware.

The author explains why they avoid information security punditry despite their professional background in the field. They choose not to use their platform to discuss infosec topics that are their primary area of expertise.

The article discusses electronic circuit design topics that are regularly featured on the blog, which attracts many readers interested in this technical subject matter.
