Before installing the system to do a ghost, in order to achieve perfection, every time you do ghost will manually clear the Event Viewer all Windows EventLog log.
Later, after using Windows 2008 r2/win7, the incident was much more complicated, so it was out of control.
Then some colleagues asked how to clear them all, because one by one, at the Microsoft level there are many directories, to completely clean up half an hour, and then after the removal, not practical.
Today, when I play Hyper-V, I
The ASP's system defaults to GB2312, and sometimes the output XML encounters a problem: In most cases, XML is required to be UTF-8 format.
If we directly specify is not enough.
The correct one should be:Dim originalcoagepage
Originalcoagepage = Session.CodePage ' remembers the original CodePage (default is 936)
Session.CodePage = 65001 ' Set new CodePage (UTF-8)
Response.Charset = "UTF-8"
Response.ContentType = "Text/xml"

Session.CodePage = Originalcoagepage ' CodePage recovery

Just last December, one idea was to use node to crawl the data of the microblog, so it simply encapsulated a Nodeweibo library. After a year, not how to maintain, midway also changed the function form to the configuration file. Some of the other projects that have been done are offline, in order to be more focused on front-end Node.js. Occasionally see more than 60 downloads a day, the continuous use of this library, but see a few
