A new app called ZuckOff has been developed to detect and alert users when someone is recording them with Meta Glass smart glasses. The app uses AI to scan the surroundings for the glasses and alert the user before they see the glasses, giving them a chance to take action.

A user, going by the handle 'bkovac', has successfully modified a $20 4G wireless hotspot, specifically the ZTE MF823, into a device that can send text messages. The modifications involve replacing the device's original firmware and adding a small microcontroller to handle serial communication. This allows the user to send and receive SMS messages using the device's 4G connectivity. The process of modification is outlined in a detailed guide on the author's GitHub page, including the necessary hardware and software components, step-by-step instructions, and code examples. The author notes that the device's original purpose was for internet access, but the modified device can be used as a dedicated SMS sender or receiver, potentially useful for IoT applications or other use cases where a dedicated text messaging device is needed.
