For PHP developers who only know how to preview PHP pages using Apache or nginx, this is an undiscovered gem. Although you cannot use the PHP built-in web server in the product environment, this function is a perfect tool for local development. Whether or not I

Uncover new features of SQL Server 2014 (2)-SSD Buffer Pool (buffer Pool) expansion, 2014 Buffer 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

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

Its data fragments will be moved from SSD blocks to SAS blocks.Benefits of the new FAST layered strategyThe new policy enables the most expensive and fastest-performing hard disks to be put into use first, making full use of the disk to get the most cost-ef

C #4.0 new features (2) named parameters, optional parameters for interoperation with COM 1. Introduction C # (2.0) is a pure object-oriented language like Java. They all use overload rather than optional parameters. However, for other external programs used, COM components often do not require all parameters to be specified (this is common in many components written by VC and VB or ironpython objects, they

the light field display technology.Now the solution for Microsoft's patent display is to combine two display technologies to achieve HoloLens's wide field of view objectives. Simply put, the virtual object is rendered by selecting one of the display systems based on the characteristics of the virtual objects. For example, in a device that has two display systems at the same time, a device based on the waveguide display technology provides the user with a virtual object in the face space. The di

At the same time, programmers should pay special attention to the relationship between the probation period and the labor contract to protect their rights and interests from infringement. No fixed period contract is not a safe deposit box In the past, many people thought that as long as they have been working in an enterprise for

password is the password you fill in when you install it. What if you forget the password? At this point, turn off SQL Plus, open the cmd command prompt, and then enter: Set ORACLE_SID=ORCLSqlplus/as SYSDBA This will enable you to log in as a sysdba. You can then modify the password for all users: Alter user username identified by password; You can also unlock the user: Alter user username account unlock; Also, viewing dba_user can only be done under the DBA's capacity: Copy Cod
