is used when reading a byte from the stream inside this method, which causes a large try block to be dispersed into several small try blocks. The test, the time is 1089ms, eh, or a little slow. Speed is now more demanding than space, not to mention that reducing the 10 bytes saved by the try block is largely negligible. So this optimization has failed again. Summary: When you can use simple flow, do not use complex flow, do not believe in theory, only to try to know. Note: The test data is No

, horror so! We are using the word "SLR camera" to compare, to see Baidu Library rankings: Results on the third page has Baidu library rankings. That is also the library, why SEO rankings far away, and SLR camera ranking is really good? is not the two key words compared, SEO heat, index less than the latter? We compare the Baidu index of these two words. The figure is as follows: From the above figure we can see, SEO Baidu Index probably between 7000--18000, and SLR camera the

Label:MongoDB can be started by command line and configuration file, the specific command is as follows: Command line: [[email protected] MongoDB] # ./bin/mongod--dbpath=/data/db Configuration file: [[email protected] MongoDB] # ./bin/mongod-f mongodb.conf However, both of these methods start the MongoDB process in the foreground, and if the session window is closed, the MongoDB process also stops. But MongoDB also provides a background daemon way to start, only need to add a "--fork" parameter,
