I have a buyer table buyer, about 10,000 records; a seller table sale, about 50,000 records. There is some correlation between the buyer and the seller, which is recorded in the partner table, and the key fields in the partner tables include Buyerid,saleid and Linkmanid, where Linkmanid is one of the sellers ' salesmen. There is also the concept of a contact in the system, for each buyer, if it and the sell
through a mechanism known as a partner system . The partner system manages the spare page and tries to assign pages to the allocation request. It tries its best to keep the memory area contiguous.It is assumed that scattered small pages are not considered. will cause memory fragmentation. and makes it difficult to apply for a large section of pages in a contiguous area. It will result in inefficient memory
1. Principle Explanation
The Linux kernel uses a memory paging model that applies to both 32-bit and 64-bit systems, and two-level page tables are sufficient for 32-bit systems, and four-level page tables are used in the x86_64 system, as shown in Figure 2-1. The Level four page table is:
L Page Global Catalog (page Global directory)
L Page Superior directory (page Upper directory)
L Page Middle directory (page Middle directory)
L Page tables (page table)
The page global catalog contains the
In the area of mobile payments, Alipay pays a huge share, according to the report published by Eric Consulting: 2014Q3, Alipay has won 82.6% of the market share, the dominance of mobile payments is increasingly stable. Tenpay paid the force point in the micro-letter payment and Hand Q payment, in the mobile payment pattern achieved 10% of the market share, ranked second.
Alipay's dominance in the field of mobile payment makes it necessary for us to comb the flow of Alipay mobile development. Th

The bottom layer uses the partner algorithm to manage the Memory Page. The system divides all idle memory pages into 10 groups. The size of memory blocks in each group is 1, 2, and 4 ...... 512 memory pages, each gr

Convert (varchar (10), getdate (), 120) returns:
Reminder: in useDate FunctionsThe date value should be between January 1, 1753 and January 1, 9999. This is the date range that the SQL server system can recognize.

origin masterIf you want to push other branches, such as Dev, change to:$ git push origin devHowever, it is not necessary to push the local branch to the remote, so which branches need to be pushed and which do not?
The Master branch is the main branch, so synchronize with the remote at all times;
The Dev Branch is a development branch, and all members of the team need to work on it, so they need to be synchronized with the remote.
Bug branches are only used to fix bugs locally
