Because it ch is a pointer in itself, we can pass the Goroutine function call directly to the ch past, instead of ch taking pointers, so all the same goroutine point to the ch same actual memory space.

enterprises, IT loses 5 hours of productivity.
In the data center and telecom fields, technical staff will also create additional risks when they accidentally unplug some plug that should not be pulled. Assume that a VoIP switch or a key server is accidentally disconnected. As I have reported many times in recent news, what if a device with critical information gets disconnected? How does the network administrator know who is on the network? How are these operations recorded?
The biggest benefi

file store. Because the resilient hashing algorithm is used, Glusterfs does not require a dedicated Meta-data server to hold the metadata, thus avoiding the entire cluster being unavailable due to a meta-data server outage.
It is precisely because the metadata server does not need, so glusterfs in multiple mount points at the same time to read and write data, its overall performance is very prominent.

The output parameter h equals 0 or 1, if h=0, the original hypothesis is accepted at the significant level 0.05, the X obeys the normal distribution, and if 1, the original hypothesis is rejected at the significant level 0.05.
