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。

n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
