Short session expiration does not help security
Summary: Short session expiration times may not improve web application security as much as previously believed. While current security advice suggests using short timeouts, major platforms like Gmail and GitHub allow users to stay logged in indefinitely. Short session timeouts can have security and user experience costs, and the threats they aim to prevent can be addressed through other measures like disk encryption and HttpOnly cookies. Companies like Google, Microsoft, and Facebook consider longer sessions an acceptable risk.

Sargablock: Bricks from Seaweed
Summary: Sargablock is a construction material made from sargassum seaweed, a brown algae that affects Caribbean beaches and the tourism industry. Developed by Mexican entrepreneur Omar Vasquez, the bricks are made using a mix of 40% sargassum and 60% other organic materials. The first sargassum house, Casa Angelita, was built in Quintana Roo, and the goal is to provide affordable housing in the Riviera Maya. The initiative has gained interest from countries like Belize, Jamaica, Puerto Rico, and the US.
