  • Python: Streaming Input with Subprocesses

    - by beary605
    Since input and raw_input() stop the program from running anymore, I want to use a subprocess to run this program... while True: print raw_input() and get its output. This is what I have as my reading program: import subprocess process = subprocess.Popen('python subinput.py', stdout=subprocess.PIPE, stderr=subprocess.PIPE) while True: output=process.stdout.read(12) if output=='' and process.poll()!=None: break if output!='': sys.stdout.write(output) sys.stdout.flush() When I run this, the subprocess exits almost as fast as it started. How can I fix this?

  • database design: table with large amount of columns (50+) or many sub tables with small amount of co

    - by Guillaume
    In our oroject we already have a lots of tables (100+). Some of them contains a lot of columns (50-100) and we are facing the need of adding more columns from time to time.

  • How do I connect StaticListableBeanFactory with ClassPathXmlApplicationContext?

    - by Aaron Digulla
    In the setup of my test cases, I have this code: ApplicationContext context = new ClassPathXmlApplicationContext( "spring/common.xml" ); StaticListableBeanFactory testBeanFactory = new StaticListableBeanFactory(); How do I connect the two in such a way that tests can register beans in the testBeanFactory during setup and the rest of the application uses them instead of the ones defined in common.xml? Note: I need to mix a static (common.xml) and a dynamic configuration. I can't use XML for the latter because that would mean to write 1000 XML files.

  • Is there a template engine for Node.js?

    - by Seb
    I'm kind of falling in love with Node.js not because you write app code in javascript but because of its performance. I really don't care a lot about how beautiful a server side language might be but how much requests per second it can handle. So anyway I'm looking forward to experiment building an entire webapp using Node.js (and going back to the actual question) is there a template engine similar to let's say the django template engine or something similar (that at least allows you to extend base templates) available for Node.js?

    I would like to take out a parameter from url by it's name without knowing if it is the first, middle or last parameter and reassemble url again. I guess it is not that hard to write something on my own using CGI or URI, but I imagine such functionality exists already. Any suggestions? in: http://example.com/path?param1=one&param2=2&param3=something3 out: http://example.com/path?param2=2&param3=something3
