The article compares the health risk of a full-body MRI to that of smoking for one year, listing alternative activities with equivalent risk such as a high-risk pregnancy, climbing the Matterhorn, riding 10,000 km on a motorcycle, two BASE jumps, or a day on the frontline in Ukraine.

The author explores data-directed programming in Haskell, as introduced in SICP section 2.4.3, focusing on complex numbers that can be represented in both rectangular and polar forms with operations to query real, imaginary, magnitude, and angle values.

The article explores SICP's concept of tagged data to handle multiple representations of complex numbers (rectangular vs. polar forms) in Haskell. The author deliberately mirrors the original Lisp-based SICP solution, including dynamic typing, to demonstrate how code can support different data representations without forcing a single storage format.

The author tests the new open-weights GLM 5.2 model against Gemini 3 Flash by having them play text adventure games within a fixed budget of $0.15 per attempt. A harness tracks achievements earned in each game to compare the models' performance.

The article examines a Formula One driver's claim that winning the Monaco Grand Prix is determined nine out of ten times by qualifying position. It questions whether this is an accurate statistical prediction or just an offhand remark, given the narrow Monte Carlo street circuit's limited overtaking opportunities.

The author argues that top-tier LLMs generate code that is about 10% more complex than necessary for easy tasks, and that this added complexity is often overlooked because it immediately solves the problem at hand. This pattern, observed while using a frontier model to generate CRUD plumbing code, could have negative consequences for long-term maintenance.

The article argues that Lucas Costa's concept of "backpressure" for systems handling code-generating AI is a misnomer. Backpressure signals upstream processes to slow down, while Costa's suggestions are about improving quality, not reducing quantity. The author proposes "lean manufacturing" as a more accurate analogy for managing unstable inputs from AI-generated code.

William Sealy Gosset, a Guinness brewer, improved beer by developing new statistical methods, publishing under the pseudonym "Student." He recognized that calculating 90% confidence intervals for the mean by assuming a normal distribution is incorrect.

The article argues that commonly cited stock market return figures (6–16%) are misleading, recommending 4% as a more realistic assumption. This accounts for compounding (CAGR of 8–11%), inflation of 3–4%, and 1–3% in costs/taxes, resulting in a net real return of 2–6%.

The article explains the alpha-max plus beta-min algorithm, a mental shortcut for estimating the Pythagorean sum c = √(a² + b²) without heavy computation. It approximates c as max(a, 0.9a + 0.5b), which is useful for combining variances, computing radii, and similar tasks.

At Henley Royal Regatta, teams are randomly assigned starting stations (Berkshire or Buckinghamshire), but historical data shows the Berkshire station winner in 53.5% of 7,555 races—a statistically improbable result suggesting either non-random assignment or unequal starting advantage.

The author describes how their RSS feed previously only included titles and dates, and explains the two-step technical process used to generate it: first constructing an Org-mode syntax tree in Emacs Lisp, then exporting it via the ox-rss backend.

The article demonstrates how to implement the classic Fizz Buzz programming problem using monoids in functional programming, showing how combining semigroups and monoids can elegantly solve the problem by composing transformations.

The article explores how to understand complex systems by breaking them into components, identifying feedback loops, and observing behavior over time rather than focusing on static snapshots.

Spaced repetition is a learning technique that uses increasing intervals between review sessions to improve long-term memory retention. This beginner guide explains how it works, its benefits, and answers common questions about implementing the method effectively.

The article argues that transparent leadership, which involves openly sharing information and decision-making processes, is more effective than servant leadership. It suggests transparency builds trust and empowers teams better than the traditional servant leadership approach.

The article discusses using the Dialog programming language to solve Advent of Code challenges. It explores how Dialog's natural language processing capabilities can be applied to programming puzzles and problem-solving tasks.

The article discusses software deprecation strategies, emphasizing the importance of clear communication, providing migration paths, and setting realistic timelines. It argues that effective deprecation requires treating it as a feature rather than an afterthought, with proper documentation and tooling support.

The article explains how to package Perl and shell scripts for deployment on NixOS, covering dependency management and reproducible builds. It demonstrates creating Nix expressions to handle Perl modules and shell dependencies in the Nix ecosystem.

MIL-STD-882E establishes a standardized approach to software control levels for military systems. The standard defines categories for software control based on criticality and safety impact. It provides guidelines for managing software throughout the system lifecycle to ensure safety and reliability.

The article discusses the benefits of playing Go on a 9x9 board, highlighting how it offers faster games and clearer strategic patterns compared to larger boards. It emphasizes that 9x9 Go provides an excellent learning environment for beginners while maintaining the game's core strategic depth.

The article presents benchmark results for Gemini 3 Flash, comparing its performance across various tasks including reasoning, coding, and mathematics against other large language models. The updated evaluation provides insights into the model's capabilities and relative strengths in different domains.

Global disaster costs have risen dramatically from 1900 to 2024, with inflation-adjusted losses increasing significantly in recent decades. The data shows a clear upward trend in economic damage from natural disasters worldwide over this 124-year period.

The article argues that a kitchen slide rule is a useful tool for cooks, allowing for quick conversions between measurement units and recipe scaling. It explains how this analog device can simplify cooking calculations without requiring digital technology.

The ACX 2025 Prediction Contest Retrospective analyzes the results of the annual forecasting competition, examining participant performance and prediction accuracy across various events. It discusses statistical outcomes and insights gained from the contest's questions and scoring methodology.

Nvidia's stock price has experienced significant volatility, with some analysts predicting a potential crash due to concerns about overvaluation and market saturation. The company faces challenges despite its strong position in AI and semiconductor markets. Market observers are closely watching for signs of a correction in Nvidia's stock valuation.

The article applies survival analysis techniques to examine the tenure of U.S. Supreme Court justices, analyzing factors that influence how long justices serve on the Court. It uses statistical methods to study judicial longevity and potential retirement patterns.

The article discusses methods for solving systems of equations more efficiently, focusing on computational techniques and algorithmic approaches that can accelerate the process beyond traditional methods.

The article discusses principles of succession planning, examining how organizations and systems transition leadership and authority. It explores various models and frameworks for ensuring continuity during leadership changes.

Wilks' tolerance intervals provide a statistical method to determine intervals that contain a specified proportion of a population with a given confidence level. The approach is based on order statistics and is particularly useful when dealing with limited sample sizes. This method has applications in various fields including engineering, manufacturing, and environmental monitoring.
