part of the business to be asynchronous, reduce system pressure. ]Answer: Hair Weibo itself this thing, need to go through a long chain of transactions, so we can interrupt the chain, it will be asynchronous, after receiving the Weibo push it into the MessageQueue, and then let its asynchronous update processing.Question: [v] under the pressure of high concurrent requests, how can the corresponding speed be guaranteed. ]Answer: A wide range of application caches, cache,memcached, and in-memory

address is related:MAC address and IP of the last 3 paragraphs are always the same, the first 3 of the MAC is always fixed, check the multicast IP address and MAC address is mapped, if the guess is right 数据发送 this point we found, and then think about how to receive it on the chip.Since it is stored in the MAC data, and in the sniffer should be able to see the MAC address, check the next 802.11 protocol, the frame head can see the MAC address, the data will be sniffer to the frame header resolut

, under the assumption of the internet security threat model, security control measures at the network boundary can be taken to ensure the security of the entire network. The threat model of Intranet security is more comprehensive and meticulous than the Internet security model. It assumes that any terminal, user, and network in the Intranet network is insecure and untrusted, threats may come from both the Internet and any node on the Intranet. Therefore, in the threat model of Intranet security

the verification code This file function is relatively simple, mainly pop up fake QQ exception box.For details, refer to the "account exception" dialog box, where the color Verification Code image is false: Figure 8 Comparison Between the QQ exception dialog box popped up by the virus and the normal dialog box Vi. Analysis of Technical Points 1. Release the fake System File msimg32.dll to the qq director

and there is a high risk. In addition to vertical scaling, we choose horizontal scaling, that is, adding servers, unlimited performance expansion, of course, there are a lot of content in it. How to back up and synchronize databases is a problem that needs to be considered and solved, in addition, we also need to consider the problem of data duplication between so many machines. In addition, it is possible to cache the database to memcached or use mysql proxy to implement connection pool and ot

Label:Oracle's hints feature is a relatively strong feature and is a complex application, and hints are only a recommendation to Oracle, and sometimes Oracle may not follow the prompts for cost considerations. According to the practical application, the developer is generally not recommended to apply the Oracle hint, because each database and server performance is not the same, it is likely that one local performance improved, but the other place is down, Oracle in the SQL to perform the

consistency guaranteed? Where are the challenges of high complexity systems? Can you identify the areas that your business corresponds to? Is it one or more? Can the business be reasonably abstracted, and the changes in business rules can be achieved at a very small cost? Data consistency, security can be guaranteed? Does it hold the method of object-oriented analysis and design? When I list the questions you are sure to answer, I think technically y

automata technology in TERARKDB, the self-motive is a state transfer diagram, which is used to express data, along the edges of the graph, to access the nodes according to certain rules, so that the required data can be extracted. Using traditional techniques to store this graph, memory consumption is large, and Terark uses succinct technology to compress this state transition diagram. The essence of succinct technology is to use bitmap to represent data structures, and memory usage is greatly
