尝试从公司电脑链接家里的服务器，结果ssh总是提示失败，一脸懵逼，心想貌似也没错误。为什么家里能连，在群晖上就不能连了，直到昨天晚上才发现用户名错了，脑子是个好东西，不过我貌似也不大有。
昨天下午就在派送的快递今天还没到，快递员手机关机了也联系不上
刚刚又看了下终于换人派送了，神奇~~
cdn问题续
之前的理解是错误的，应该还是百度cdn证书的问题，刚客服回复取消部署重新部署就可以了。于是拿另外一个网站试了一下果然是这么个问题。之前的恢复了应该是客服帮忙给重新部署了，和自己oss的cdn关系不大。哈哈哈。
图片镜像cdn异常
昨天晚上百度cdn突然挂了，到晚上十一点多恢复了，但是自己的图片域名还是有问题。一直访问不了，今天早上又看了一下，另外一个域名有的图片能访问，这个就很神奇。今天早上想着是不是oss的问题，进去之后发现配置了阿里的cdn但是没启用，删除阿里的cdn配置之后问题竟然解决了。这尼码~~
百度云加速挂了~~

是UPS吖（三）–-树莓派
装ups的另外一个目的就是为了保证树莓派的存储卡不会因为意外断电而出现问题。其实要解决这个问题个人觉得也简单，毕竟也是个linux啊。可以基于nut实现。
The primary goal of the Network UPS Tools (NUT) project is to provide support for Power Devices, such as Uninterruptible Power Supplies, Power Distribution Units, Automatic Transfer Switches, Power Supply Units and Solar Controllers. NUT provides a common protocol and set of tools to monitor and manage such devices, and to consistently name equivalent features and data points, across a vast range of vendor-specific protocols and connection media types.
NUT provides many control and monitoring features, with a uniform control and management interface. If you are just getting acquainted with NUT, that page also explains the technical design and some possible set-ups.
More than 170 different manufacturers, and several thousands of models are compatible.
