I have 4 reasonably complex r scripts that are used to manipulate csv and xml files. These were created by another department where they work exclusively in r.
My understanding is that while r is very fast when dealing with data, it's not really optimised for file manipulation. Can I expect to get significant speed increases by converting these scripts to python? Or is this something of a waste of time?
The title says it all, how do I access properties (title, state,...) of instance variables from within a class method of an other implementation file? I tried @synthesize but I couldn't get it to work.
Hi there,
So I'm following thiese instructions:http://mark-kirby.co.uk/tag/osx/
and so far i've cloned the project I want to work on and created a branch.
Now I wish to add files that exist in another folder on my machine... but I keep getting the following:
fatal: pathspec 'Users/mic/OnePageCRMVC/MKTsite25-05/index.html' did not match any files
However, the file definitely does exist...
Am I trying to do something that is not allowed and the error message is throwing me off?

Thanks!

I have a BASE_DIR setting in my settings.py file:
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
I need to use this variable in my logging.ini file to setup my file handler paths.
The initialization of logging happens in the same file, the settings.py file, below my BASE_DIR variable:
LOG_INIT_DONE=False
if not LOG_INIT_DONE:
logging.config.fileConfig(LOGGING_INI)
LOG_INIT_DONE=True

Given a compressed archive file such as application.tar.gz which has a folder application/x/y/z.jar among others, I'd like to be able to take my most recent version of z.jar and update/refresh the archive with it.
Is there a way to do this other than something like the following?
tar -xzf application.tar.gz
cp ~/myupdatedfolder/z.jar application/x/y
tar -czf application application.tar.gz
I understand the -u switch in tar may be of use to avoid having to untar the whole thing, but I'm unsure how to use it exactly.

Does anyone know how to Unzip password protected files in an SSIS package?

We are using a SQL server 2008 with .Net 3.5 on the windows server 2008 R2.
Is there a way (without buffering the whole Inputstream) to take the HttpServletRequest from a Java Servlet and write it out to a file using all NIO? Is it even worth trying? Will it be any faster reading from a normal java.io stream and writing to a java.nio Channel or do they both really need to be pure NIO to see a benefit? Thanks.
