Recently, we have made object-oriented extensions for JScript so that you can define classes in JScript (TM) and write real object-oriented code. I named the extended JScript oxscript. The features to be implemented are as follows: Oxscript is an object-oriented extension for JavaScript.The following features will be provided by oxscript:1. class definition;2. Final class;3. abstract class;4. Inheritance;5. Overriding;6. abstract function;7. polymorph

First, install and load the TM package. 1. Read text x = readLines("222.txt") 2. Build a corpus > r=Corpus(VectorSource(x)) > r A corpus with 7012 text documents 3.

Java HotSpot (TM) 64-bit Server VM warning:ignoring option maxpermsize=256m; Support was removed in 8.0 The JDK 8 compatibility Guide indicates that, in Java 8, the command line flag MaxPermSize has been deleted. The reason is that the permanent generation is removed from the hotspot heap and transferred to local memory. So to delete this message, edit the maven_opts environment user variable: Java 7 maven_opts-xmx512m-xx:maxpermsize=128m Java 8

(distributed lock): For OPS (parallel server);(5). PCM Locks (parallel cache management Lock): For OPS (parallel server).The most important lock in Oracle is DML (also known as data locks, lock). The purpose of a DML lock is to ensure data integrity in the case of concurrency. In Oracle databases, DML locks mainly include TM and TX locks, where TM locks are called table-level locks, and TX locks are called

remote nodes (hosts) can be synchronized in real time and Data Consistency can be ensured. Therefore, when the host on the local node fails, the host on the remote node will retain a copy of identical data for continuous use to achieve high availability.Because DRBD synchronizes data in blocks over the network, it does not depend on upper-layer devices such as file systems, LVM, and Soft RAID, it can be used for database file synchronization (different from rsync file synchronization ).

Linux/unix-time timestamp processing conversion functionThe time function under LinuxWe can often use time in programming, such as getting the system time (to get the system's year, month, day, hour, minute, second, week, etc.), or to do something at intervals, then we use some time functions.There are two common ways to store storage time under Linux:One is from 1970 to now after how many seconds;One is to use a structure to store the date and time of each month and seconds.time_t This type is
