to live well. Add a Trunkbitforce32bit method, the number of all arithmetic operations after the high shielding, is to deal with the 64-bit system redundant bit problem. The result is a 32-bit Linux environment run is not compatible, because PHP in the arithmetic processing overflow, will automatically try to convert int float. When a negative number overflows, this operation correctly preserves accuracy under windows, but there is a problem with Linux. The following code: $a =-4294967295; ec

Introduction Another good feature in SQL Server 2014 is that SSD can be virtualized into a portion of the memory for the SQL server data page buffer. By using SSD to expand the buffer-pool, a large number of random iops can be carried by SSD, thus greatly reducing random iops and page-out for data pages. SSD as buffer pool SSD is a solid state drive. Unlike traditional disks, SSD has a head moving part. Therefore, random read/write iops is much larger than traditional disks. Using SSD as an

Brief introduction Another very good feature of SQL Server 2014 is that SSD can be virtualized as part of memory for use by SQL Server data page buffers. By using SSD to extend Buffer-pool, a large number of random IOPS can be hosted by SSD, which reduces the random IOPS and page-out for data pages. SSD as Buffer Pool SSD is a solid-state drive, unlike a traditional disk with a magnetic head moving part, so random read and write ioPS far larger than the traditional disk. Using SSDs as an exte

{ get { return _prodcutname; } set { _prodcutname = value; } } } Automatic attribute writing: public class Prodcut { public string _productid { get; set; } public string _prodcutname { get; set; } } If the get/set attribute is empty, a member variable and a public get/set will be automatically generated in the class. You can also set the access level of get/set separately, as shown below: public class Prodcut { public
