We have learned that you can use the following days commands to view information about the Linux kernel version and the Ubuntu release:Uname-rUname-aCat/proc/versionLsb-release-aWait a minuteYou can see that the kernel version of the current ubuntu12.04.5lts is Linux 3.2.0-23-generic-pae, so what are the rules for version numbering? What does generic and PAE mean?First, the Linux kernel version number sequenceThe kernel version number for Linux is typically:The major version number. minor versio

This section is about two commands su and sudo are all about getting root permissionsThe parameters of the sudo band are-l-c-m-v, etc.-L gives Sudo permission for the current user-C Execute Command-V time stamp-M Delete timestampAnd then there's the Setup command for sudo.Usually use regular visudo.And then step by step, this doesn't easily cause a big mistake.You can also edit the configuration file/etc/sudoersAbout configuration formatsRoot AllThat's probably all I remember.20161128l04-

thread will be freed, and the other blocked threads will be able to get to the page successfully. This avoids the need for multiple threads to put the corresponding page in the cache while the get-to element is null, resulting in unnecessary resource wastage. It would be appropriate to use Blockingcache if there is a need for page caching. More information about Ehcache using page caching will be introduced in the next Article blog post.The Blockingcache just mentioned is designed for page cach

Portal: http://poj.org/problem?id=3693Title: Give a string, the repetition of the most repeated number of consecutive substrings;Analysis:Enumerates the length of a repeating cell, and then naturally enumerates the starting point. With RMQ processing, the longest prefix of the suffix i,i+l is used.Lcp/l+1, the number of repetitions of the string for the current adjacent L-length unit, but because of the i+=l, improves the efficiency, but I do not necessarily happen to be the starting point of th
