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。

If riding a bucking bronco is your idea of fun, you’re going to love what the stock market has in store. Consider this past week’s ride a preview.The week’s action didn’t look like much, if you didn’t know better. The Dow Jones Industrial Average rose 213.12 points or 0.6%, while the S&P 500 advanced 0.5%, and the Nasdaq Composite ended little changed.
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
