软件调试的基础方法: 控制变量法。即在保持大环境不变的情况下，改变少量参数来确定是不是这些参数引起的问题。比如两个客户端连接同一服务器，一个连不上一个连得上。可用的方法有: 1) 比较两个客户端配置文件的差异 2) 在两个客户端上使用相同的配置文件 3) 检查客户端版本 4) 检查环境，如操作系统版本。 当确定是某一个地方出问题时，比如配置文件不一样，则可以把可连通的配置文件逐条修改至不可连通的配置文件，以确定是哪一条产生的问题。

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
With the help of the Search Filters option, users can now filter search results by type. They can do that by using the new tabs: Media, Links, Files and others. Searches can be done based on the particular time period like by typing in the date or even “Yesterday”. If users type in the name of a person, group, channel or bot, an extra filter will be applied to the searches.
