behind the NAT. To achieve the goal, a hole can be used to find a path, but not by forwarding. When both hosts are located after symmetric NAT, the hole-piercing technology may fail. The turn protocol allows a host after NAT to request another host to forward. The client can transfer to the other end through the server. And you can control how forwarding ends. This client obtains an IP port pair on the server, also known as the forwarding port address. The server forwards the packet to the cli

Because server A cannot see the witness server W or the original mirror partner server B, you must enter the disconnected state and make the database unavailable. Server B and Server w can compose quorum. Server B cannot see server A, so Server B tries to become the primary server and bring its database online. Because Server W also does not see server A, it agrees to server B. Server B now has a quorum, serves as the primary server role fo

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.

MySQL series: Memory Management for innodb Engine Analysis Innodb implements its own memory pool system and memory heap allocation system. In the innodb memory management system, there are roughly three parts: basic memory block allocation management, memory partner allocation, and memory heap allocation. The main purpose of innodb to define and implement a memory pool is to provide memory usage and efficiency, preventing memory fragmentation and memo

Picture + text: This should be more common, only one unit (figure + text) on it.Picture needs to be marked wide, because the engineer to set the picture area, from the background, so to speak, the software in addition to the horizontal screen full of figures, basically all the pictures should be marked wide

increased social interaction. Every time I tell someone that I'm working remotely in my apartment, one of the most common reactions is "I miss the feeling of interacting with my colleagues."

Nickolas means, in his blog post, "Let remote work go smoothly," describes

Title Description Description N Small partners (numbered from 0 to n-1) sit around and play the game. The n positions are numbered in a clockwise direction, from 0 to n-1. Initially, the No. 0 partner at position No. 0, the 1th small partner in the 1th position, ..., and so on.The rules of the game are as follows: each round of the No. 0 position of the small partner
