Meta’s smart glasses privacy problem has taken another turn. After WIRED found inactive face-identification references inside the Meta AI app, the same code has now reportedly vanished in a follow-up app update.

The code was reportedly connected to an internal effort called “NameTag.” WIRED found that the system was not switched on for users, but its presence suggested Meta had gone beyond a loose concept and had started testing how face identification might work inside its smart glasses ecosystem.

Shoppers looking for a cool-weather comfort item may want to take note of a new federal warning about heated insoles sold online. According to the U.S. Consumer Product Safety Commission, some of the products can catch fire even when switched off.

Federal regulators are urging consumers to stop using COOWALK and COOWALI heated insoles right away. The agency says a lithium-ion battery in the heel can overheat, explode, or ignite, creating a serious risk of burns and house fires.
