• pass commands to an running R-Runtime

  - by tiny81

  Hi, is there a way to pass commands (from a shell) to an all ready running R-runtime/R-Gui, without copy&past. So far I only know how to call R via shell with the -f or -e option, but in both cases a new R-Runtime will process the R-Script or R-Command I passed to it. I rather would like to have an open R-Runtime waiting for commands passed to it (via what ever connection is possible). regrads, Tiny

• Render a template in Ramaze

  - by pkulak

  I've got a template for a partial that I'd like to use and I'm wondering if it's possible to just render the thing without needing to send a mock request to a controller. I'm never going to need to render this to an AJAX call, so it seems silly to set up a controller and action, not to mention the security issues with making a private partial open to the world.

• MAC OS X: How to determine if filesystem is case sensitive?

  - by trojanfoe

  I have used the statfs(2) system call to get many characteristics of a Mac OS X filesystem, but it doesn't tell me if the filesystem is case-sensitive or not. I need this information as the application I am developing will be moving many files around and I want to detect potential loss of data due to files being moved from a case-sensitive filesystem to a case-insensitive filesystem. Can anyone suggest a way of detecting this?

• operator overloading c++

  - by segfault

  When overloading operators, is it necessary to overload = <= and !=? It seems like it would be smart for c++ to call !operator= for !=, ! for operator<= and !< for operator=. Is that the case, or is it necessary to overload every function?

• How to do bulk update of views?

  - by Shaul

  My database has about 30 views, most of which have a reference to another database on this server (call it DB1). Now, without going into the reasons why, I need to update all those views to DB2, also on the local server. I would hate to have to do this manually on each view. Is there some SQL query I can run that will replace all occurrences of the string 'DB1' with 'DB2' in all my views?

• Does main() need to be in every script containing handlers?

  - by Will Merydith

  Experienced Java programmer trying to learn Python. I have an applicaiton on Google App Engine and want to move my admin Handlers to a separate file. So now I have main.py and admin.py. I've set up app.yaml to route traffic properly, and have added the call to WSGIApplication() in each file to route to the appropriate Handler. My question is does each script file need def main() and the corresponding if statement: application = webapp.WSGIApplication([(r'/admin/(.*)', Admin)], debug=True) def main(): run_wsgi_app(application) if __name__ == '__main__': main()
