Panasonic has developed vacuum insulating glass units made of tempered glass

Panasonic entered the nascent vacuum insulating glass market in 2017. The company produces thin pairs of glass with a vacuum inside, the thermal conductivity of which is much lower than that of traditional double-glazed windows with air or inert gases.

We write our own capped expirationd module for tarantool

Why hacker attacks on IoT devices are dangerous: real stories
