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。

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
