c# - Which one to use: Managed vs. NonManaged hashing algorithms -

In a regular C # application, the class is used for hashing: xxxManaged or xxx (i.e. SHA1 managed / <> code vs SHA1 ) and why?

  A non-managed hash that ends in  *** Cng  There are also platform restrictions. They are much faster than managed options, but will run on runtime on Windows XP, for example. If you know that your program will always be run in Windows 7, Vista SP1 or 2008, however, they will generally perform better than managed versions, even with the original interop overhead.  
 If you are writing a general purpose program, working with  *** managed  classes will be easy, because they will always work.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -

Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
