Bungie's Content Vault: A Digital Black Hole?

In a bizarre twist in a copyright lawsuit, Bungie is unable to provide the court with evidence of early Destiny 2 content, including the Red War campaign, due to its “content vault” system. This reveals the vault isn't simply storage; it functions more as a content shredder, inaccessible even to Bungie itself. This explains the scarcity of returning original Destiny 2 content, while remakes of Destiny 1 content are more common. Unless significant effort is made, the content within the vault is likely lost forever.

Stop Explaining e with Compound Interest

2025-04-11

Math classes often introduce the natural constant *e* using compound interest: a 100% annual interest account doubles with yearly compounding, becomes 2.25 times with semi-annual compounding, approximately 2.714 times with daily compounding, and exactly *e* times with continuous compounding. However, this is misleading. Compound growth is exponential, but the example uses linear division of compounding periods. Banks must separately publish the interest rate, compounding interval, and annual percentage yield. There are far more elegant ways to introduce *e*, such as its unique property of being its own derivative, or its crucial role in Euler's formula. These approaches don't require prior knowledge of *e* and are mathematically more rigorous.

Google Translate Bug Turns 'Yes' into 'Forks' in Online Surveys

A bizarre bug in a Pew Research Center's 2024 online survey replaced the 'yes' option with 'forks' for some respondents. The investigation revealed a 'lightbox popup' design feature caused some browsers to misinterpret the English survey as Spanish, triggering Google Translate's auto-translation. Google Translate, however, contained a peculiar error: translating 'yes' from Spanish to English resulted in 'forks'. Pew Research Center resolved the issue by disabling the browser's translation function and improving its programming. Analysis showed the bug had a negligible impact on the survey data.

OpenAI's PostgreSQL at Scale: Best Practices and Challenges

2025-05-23

At PGConf.dev 2025, OpenAI shared its best practices for using PostgreSQL, revealing insights into database usage at one of the world's leading AI companies. They utilize a single-writer, multi-reader, unsharded architecture, successfully handling massive read loads for its 500 million active users. However, write requests became a bottleneck, prompting optimizations including load control on the primary database (offloading writes, lazy writes), query optimization (avoiding long transactions, optimizing complex queries), addressing single points of failure (prioritizing high-priority requests), and careful schema management (restricting schema changes). Despite these efforts, OpenAI encountered challenges related to index management, observability, and schema change history, prompting suggestions for PostgreSQL improvements. Veteran PostgreSQL expert Lao Feng provided insights based on his experience, showing that many issues could be solved with existing tools or methods, or even using his open-source Pigsty system. Ultimately, OpenAI's PostgreSQL cluster successfully processed over one million QPS, demonstrating the potential of PostgreSQL in large-scale applications.

Debunking the Airplane Lift Myth: The Bernoulli Fallacy

2025-04-23

The common explanation for airplane lift using Bernoulli's principle—faster air over the top, lower pressure, thus lift—is fundamentally flawed. This article argues that this "equal transit time" fallacy, while simple and intuitive, neglects crucial factors like viscosity, entrainment, and the Coanda effect, and violates Newton's third law. Lift primarily results from the downward deflection of air by the wing, a consequence of Newton's third law; even symmetrical airfoils generate lift. While Bernoulli's equation itself isn't wrong, its application in explaining lift often involves erroneous assumptions and additions.
