Just got my sixth US patent granted: US 12,774,997 B1, a moisture detection apparatus for buildings. It's a small device that slips into a wall through an outlet opening, scans for moisture, and sends the reading and its location to your phone. Catching leaks before they turn into big repairs. #patent #innovation

"Effective Immediately, all organizations using PHP for their systems are advised to be prepared for an update addressing two critical vulnerabilities. PHP is widely used for web applications. These vulnerabilities often provide a direct path to the server's file system or database. If an immediate update is not feasible, it is recommend that organizations take the system offline until it can be fully mitigated. NSA will follow up shortly with more specific guidance."
