Direct block transfer, that is, in the process of transferring a block of data between the memory and the I/O device, without any interference from the CPU, only need the CPU at the start of the process (that is, to send a "send a piece of data" to the device The process ends when the CPU polls or interrupts to see if the process is complete and the next operation is ready. The actual operation is done directly by the DMA hardware, and the CPU does something else during this transfer.Letter

This morning, I looked at Facebook's old news about one person managing 20,000 servers. is also idle oneself probably to forget a bit. It is calculated by using the 1U server for all of the Facebook servers. A standard cabinet probably puts 20 units (ideally, no network devices, no storage). A total of 1000 enclosures are required for 20,000 services. Also find a news about IDC (Century interconnection is very good in IDC, take it as an example.)

Method for obtaining pipe standard and tube outer diameter
The pipe standards determine whether the defaultpipe field exists in the second flasys. If yes, the data in cadpipe is obtained.
The uniqueness of defaultpipe is determined by the flasys drop-down list.
If "with metric tube" is true, replace the HGA obtained in defaultpipe with HGB.
If defaultpipe is PP, take the A1A field in cadflang

The above is a circuit diagram. j16 is connected to j15, and J6 321 corresponds to P2 ^ 0--p2 ^ 2, which is conducive to saving MCU resources. Among them, P1 ^ 0 and Le are connected, segment selection (determines what the digital display is), and bit selection (which one of the digital tubes is bright) is determined by the 138 decoder. Let's write the program first:
