The article discusses the vulnerabilities associated with automatic disk unlocking using TPM2 and systemd-cryptenroll or clevis. It highlights the ease with which an attacker can decrypt a disk if they gain physical access to a machine, particularly due to weaknesses in verifying the LUKS identity of the decrypted partition. Many setups allow an attacker to exploit filesystem confusion by inspecting the initrd files in an unencrypted boot partition to learn how the system decrypts the disk. By recreating a LUKS partition

The Dragon spacecraft, during its flight to the International Space Station (ISS), conducts a series of burns to progressively position itself closer to the station. After executing final docking maneuvers, it pressurizes the vestibule and opens the hatch for crew ingress. Initially, the Falcon 9 rocket launches the Dragon into orbit, where the two stages separate. The second stage accelerates Dragon to orbital velocity, after which Dragon performs system checks and initiates maneuvers to align with the ISS. It

Heuristic caching is the default behavior in browser caching when no Cache-Control header is specified. Instead of ignoring caching, it allows responses to be cached based on certain conditions. When a response isn't updated for an extended period—that is, up to a year—the client can store it for reuse. The recommended caching duration is roughly 10% of the time since it was last updated; for instance, if a resource has not changed for 10 days, it can be cached for 1 day. This
