This article aims to illustrate that when the Telethon library uses the send_file and send_message functions, it cannot set or forge the send timestamp of the message. The design philosophy of the Telegram platform determines that all messages display their true sending time to ensure data integrity and prevent the spread of false information. For users who want to archive files according to the original creation date, other auxiliary methods need to be used to label historical information, rather than relying on the platform's own timestamp function.

This article discusses whether a traceable historical timestamp can be set when sending a Telegram message or file using the Python Telethon library. The core conclusion is that Telegram's API design does not allow users to forge or modify the sending time of messages, and all messages will display the date and time when they were actually sent. The article will explain the reasons for this limitation and provide alternatives to how to include historical date information in the message content to achieve a "timeline" effect.

Telegram API, including the ability to set messages or files to send as historical dates when operating through the Telethon library. All sent messages and files will be marked with the server time when they are actually sent, which is to maintain the integrity of the message and prevent timestamp forgery. Users should manage the context of historical data through message content, file naming, or local organization.

This article discusses the problem that the output does not match expectations when executing SQLPlus commands through Runtime.exec(String) in Java applications. The main reason is that Runtime.exec(String) improperly parses command strings containing complex parameters such as spaces and quotes. The article provides two solutions: passing command parameters as an array using Runtime.exec(String[]), and the more recommended ProcessBuilder class, which provides finer process control and standard flow management to ensure that commands are executed correctly and capture the expected output.

This article aims to explore the limitations on message timestamps when sending messages and files using the Python Telethon library. The core thing is that the Telegram API (and therefore Telethon) does not allow users to set the sending time of messages in a custom or retroactive manner. The timestamps of all messages and files sent through functions such as send_file or send_message are defaulted to the current time when they were actually sent. This is a security mechanism designed by Telegram to maintain platform data integrity and prevent information tampering.

This article explores two main database design patterns that deal with polymorphic many-to-many relationships in Prisma (such as a note that can be associated with a course or lecture). The first solution adopts a single Note table, which correlates different entities through nullable foreign keys. The advantage is that the table structure is simple, but there may be field redundancy. The second solution creates independent Note tables for each entity, avoiding redundancy, but increasing the number of tables and query complexity. The article analyzes the advantages and disadvantages of the two solutions in detail and provides Prisma model code examples, aiming to help developers choose the most suitable database design based on specific business needs.

When an SQLSTATE[23000]: Integrity constraint violation: 1452 error is encountered in a Laravel application, it usually means that when trying to insert or update data into a child table, the parent table record referenced by its foreign key does not exist. This is common in batch data import scenarios. The core reason is that the value of the external key field of the child table cannot be found in the parent table, or the data type and length of the two do not match. This article will explore the causes of this error in depth, provide specific diagnostic and resolution steps, and provide preventive measures.
