Creativity for creating PSK ;-)

Ubee DDW365 XCNDDW365 and DDW366 XCNDXW3WB devices have predictable default WPA2 PSKs that could lead to unauthorized remote access. A remote attacker (in proximity to a Wi-Fi network) can derive the default WPA2-PSK value by observing a beacon frame. A PSK is generated by using the first six characters of the SSID and the last six of the BSSID, decrementing the last digit.

A WIRED investigation into internet censorship in US schools found widespread use of filters to censor health, identity, and other crucial information. Students say it makes the web entirely unusable.

Analysis of more than 117 million censorship records confirms what students and civil rights advocates have long warned: Web filters are preventing kids from finding critical information about their health, identity, and the subjects they’re studying in class.
