ruby - Fiber#alive? not defined -

मैं ruby1.9.2p180 (2011-02-18 संशोधन 3090 9) i686-linux का उपयोग करता हूं। फाइबर # जीवित है? एक अपरिभाषित त्रुटि देता है:

  फाइबर = फाइबर। नया {'हैलो' डालता है} फाइबर.लिव? = & Gt; अन्य तरीकों, उदाहरण के लिए,  फाइबर # पुनरारंभ करें ,  Fiber.ield  ठीक काम करने लगते हैं। क्या गलत है?   वैसे,  Fiber # resume  और  फाइबर # स्थानांतरण  में क्या अंतर है?   
 
  आप  को 'फाइबर' की आवश्यकता भूल गए  पहले:  
  f = फाइबर .new {डालता है 'हैलो'} = & gt; # & LT; फाइबर: 0x896109c & gt; f.alive? # नॉट विधि एरर: अपरिभाषित विधि 'जिंदा?' # & Lt; फाइबर के लिए: 0x89610 9c & gt; # से (irb): 2 # से /home/johnf/.rvm/rubies/ruby-1.9.2-rc1/bin/irb:17:in `& lt; मुख्य & gt; ' 'फाइबर' की आवश्यकता है & gt; सच है f.alive? = & Gt; सच

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? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   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...
