WeChat does not have an official "read" function, but it can be determined whether the message is viewed by the following methods: 1. Check the chat prompt status, "delivered" means that the message has arrived at the other party's device, provided that both parties enable the "message receipt"; 2. Observe the other party's online status, reply speed, avatar signature changes or withdrawal of messages to make speculations; 3.

Message deduplication can be achieved through three strategies: 1. Unique identifier combined with cache or database record processed message ID, suitable for scenarios such as order processing; 2. Current-limited deduplication based on time window, suitable for anti-flash and frequency limit requirements; 3. Persistence state plus idempotence verification, used for strong consistency systems such as financial transactions. Appropriate mechanisms should be selected according to business characteristics, and cached Bloom filters should be used in high-throughput and low-latency scenarios, and key services should adopt persistent idempotence verification, and the time window is suitable for frequency control. The design needs to take into account performance and reliability, and consider scalability and fault tolerance.

The network configuration of the Debian system is mainly implemented through the /etc/network/interfaces file, which defines network interface parameters, such as IP address, gateway, and DNS server. Debian systems usually use ifup and ifdown commands to start and stop network interfaces. By modifying the ifeline in the interfaces file, you can set a static IP or use DHCP to dynamically obtain the IP address. It should be noted that Debian12 and subsequent versions no longer use NetworkManager by default, so other command-line tools, such as IP commands, may be required to manage network interfaces. You can edit /etc/netwo
