7-Minute Workout: Science or Hype?

2025-01-01

A blog post challenges the efficacy and comprehensiveness of the 7-minute scientific workout featured in The New York Times. The author argues that while the program claims to be science-based, it heavily emphasizes leg exercises while neglecting a balanced workout for glutes, back, and core muscles—a particularly concerning omission for sedentary professionals. A more balanced approach, the post suggests, would include more hip-dominant, upper-body pulling, and core extension exercises to counteract the muscular imbalances caused by prolonged sitting.

Copyright Reform: A National Security Imperative

2025-02-01

Anna's Archive, the world's largest shadow library containing over 140 million copyrighted texts, is being used to train LLMs by Chinese companies. The authors argue this poses a national security threat requiring Western nations to reform copyright law. They propose shortening copyright terms and creating exceptions for mass preservation and dissemination of texts, allowing LLM training companies legal access to this data. This is not just an economic issue, but crucial for maintaining a lead in the AI race and even national security.

Cryptography Isn't Based on NP-Complete Problems

2025-02-13

This article explains why cryptography doesn't rely on NP-complete problems. While NP-complete problems are hard to solve quickly, cryptography needs problems that are hard on average, meaning a randomly selected instance is difficult to crack. RSA is an example; it relies on the difficulty of factoring large numbers, which is hard on average. NP-complete problems only guarantee hardness in the worst case, not average-case hardness, making them unsuitable for cryptography.

The High Cost and Complexity of Static CT Logs: A Sustainability Debate

2025-07-04

This article compares the operational costs and complexities of two CT log implementations: CompactLog and Sunlight. The author demonstrates that Sunlight's 'served directly from S3' architecture suffers from significantly higher write (22.4x) and read (500x) costs compared to CompactLog. Furthermore, Sunlight exhibits security vulnerabilities (accepting 32 spaces as a cryptographic seed), lacks caching, is complex to deploy, and has poor documentation, resulting in high operational costs and maintainability challenges. The author criticizes this design's prioritization of perceived simplicity over sustainability and security, advocating for the inclusion of smaller operators and monitors in shaping the CT ecosystem to avoid consolidation of control by large corporations or cloud providers.
