In a single-process system, updates to a data source occur sequentially, but in a multi-process system, multiple updates may execute concurrently, leading to potential race conditions that can result in incorrect data states. To prevent this, a process must acquire a lock on the data source before making updates, ensuring no other processes can access the data during this time. This method is referred to as pessimistic locking. In distributed systems, locking is more complex due to challenges like node failures and network partitions. A

The content discusses a new offline motion detection technology designed to help subway travelers keep track of their stops. Subway systems often lack reliable cell service and GPS, making it difficult for passengers to know their location and estimated arrival times when underground. The innovative solution works by utilizing the vibration signature of a mobile phone to predict the user's position between stations. To use the service, passengers simply start a trip, and the app will provide real-time updates on their predicted location, station countdown, and ETA, all without
