I. background The background of this article is the interface between the 12th Five-Year Plan and the systematics Integrated Monitoring of Westinghouse. The history recorder service is deployed as an interface for external data publishing. The history recorder service allows the systematics service to configure object data and list data to be stored and forwarded to external system processing software. The external system processing software needs to

Where did AC v come from?

The earliest commercial alternating current frequency was 60Hz and the voltage was 110 V. Its inventor Nikola Tesla was an American (immigrant) and funded by the boss of Westinghouse Electric, commercial AC power is also the first operation in the United States. The US uses the imperial unit, and the 60Hz/110v specification is used for calculation convenience.After the success of the commercial alternating current (AC) Competition, Europe quickly intr

Alice and Bob take turns and take the last stone to victory.Ideas:Because the range of the number is relatively large, it is best to find the regular solution by the results of the SG table.SG (4k+1) =

big deviation.2. The scheduler must be CFQ.3. The test tool must support cgroup restrictions.4. It is best to have random io.Here is just a rough demo of how to use FIO to constrain the IO used by the process, let's construct the following scenario:We are creating 2 1g size files for random mixed reads and writes, a ratio of 500 to 100, and a total ratio of 1000. Then theoretically you can see that a process can get more than 5 times times the IO capability of the B process.The operation is as

Compression principle and implementation of zip three

above analysis seems to require the smaller the better, but because to save the code table to the Huffman compression results of decompression, each paragraph to save a different code table, so the paragraph is too small, save the Code table after the loss, so that seems to require paragraph to be as big as possible , so as to keep the number of copies of the Code table as little as possible. Gzip took such a policy to determine the size of the paragraph: lz77 compression every

For 32bit Win2K, the size of the page is 4K bytes. The information that the CPU uses to convert the virtual address into a physical address is stored in a structure called a page directory and a page table.Physical memory paging, a physical page with a size of
