There are generally two ways to play a slide file offsite. The first method, the target computer must have PowerPoint software, directly open the file playback. Alternatively, after packaging the slide file, copy the corresponding file to the target machine to unpack the playback. These two methods are more troublesome, I think I can translate ppt file into Flash file, so it is very simple to play. Kung Fu not negative, the author found a powerconvert

the city's delay is usually only a few milliseconds, with the same room is not very good. 2, if it is an off-site 30 millisecond delay will need to focus on, because if the application is repeatedly invoked, the magnification time is not just 30 milliseconds, may be 300 milliseconds, 500 milliseconds, for many applications is unacceptable. In terms of scalability, if you're doing a lot of work offsite, your scalability doesn't theoretically have too

In large commercial applications, the data disaster recovery backup is very important and necessary. Based on his own practical experience, the author designs A set of methods for automatic data backup in different places, which can be used for reference by database administrators.

In order to ensure the recoverability of the data in the server, a remote backup database scheme is used. Offsite backup data are divided into off-site backup file data and off-site backup database data two kinds. The off-site backup file data is designed to back up files uploaded by users in the site. and offsite backup database data is the database of data backup files uploaded to the remote server. Firs

Microsoft has a hobby called binding. The one thing I hate most is that IIS is bound to Windows-upgrade IIS to upgrade the operating system, the server is not a PC, the system is not ready to reload. When using SQL Server log shipping for offsite backups, Microsoft's binding strategy pits it once again. Log shipping only supports Windows file sharing in these 1 and only 1 ways, and the server for offsite b
