postgresql - PostqreSQL in Rails: How do I make the server run locally AND accept connections on the Unix domain socket? -


Then I'm a newbie for the rail which only uses the first SQLite3, and I also run a simple rake command I'm struggling for when using PostgreSQL.

I am just trying to follow the first 5 minutes of this screencast while setting up Postgrad:

But whenever I gave directions, even when I ran rake db: create: all I get a universal error message: 

  Could not connect to the server: Permission is denied Whether the server is running locally and unix Accepts connections on domain socket "/var/pgsql_socket/.s.PGSQL.5432"?   
 I see it everywhere, but did anyone surely answer it, once and for all (if such a task was very easy)?  
 I posted Homebrew to PostgreSQL  
 When I run  which runs psql , it says that I am using one of the  usr / bin / psql  Which I believe is the origin of Mac OSX Lion (is not it a bad thing?) How can I switch to any one installed by the Homebrew, which can be found in the  usr / local / bin / psql  Is in).  
 I'm pretty sure the postgrace is running at the very least: when I  ps auxw | Grep postgres run , I get my four processes, such as:  
  Postgrej: statistics collector process postgrad: autovoke launcher process postgrad: wall author process postgrasser: author process   
 And I was also able to set my own  pg  gem just fine. I am trying to run just PostGrace all day, I appreciate any and all help!  
 Edit (with solution):  
 Reference to this link:  
  
 Actually there was a path problem, .bash_profile, and switch homebrew, using one of the  usr / local / bin / psql  usr / bin / psql  is. >.  
 After that, I uninstalled my PG Mani, and then reinstalled it, and then make the DR: Make: All started working. :)  
 Edit 2:  
 Actually, I still have problems! It's so disappointing! :)   
 
 
 Your permission may have been compromised  
  sudo Chmod-r 777 / var / pgsql_socket /   
 This allows open access to everyone, so it's OK to require your development server.  
 Now it should work.

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
