FIPS 140-3 is not a security guarantee, and auditors know it

Key Points

• FIPS 140-3 validates a cryptographic module in a specific version and configuration, not the security of the full product or deployment.

After Losses, Retail Investors Flock to 3x Leverage as 2x Product Are Restricted

Key Points

• Korean investors sharply increased purchases of U.S.-listed leveraged ETFs after domestic leverage rules were tightened.
• SOXL, KORU, and TSLL were among the most purchased U.S. products, with combined purchases of $5.1744 billion.

From boiling lead and black art: The history of mathematical typography (2017)

Key Points

• Mathematical typesetting has historically been more complex and costly than ordinary text composition.
• Modern tools such as Word and LaTeX make math publishing easier, though they differ in usability and output quality.
• The article links mathematical typography to the broader history of printing, literacy, and human communication.

Cloudflare Wallets: the programmable wallet for the agentic Internet

Key Points

• Cloudflare Wallets are designed to give users and AI agents a stable identity and payment mechanism for APIs and content.
