• Application lifetime in ASP.NET

  - by fearofawhackplanet

  This should be a simple question but I haven't managed to find the answer on google. I would like to know, in terms an idiot can understand, exactly what application lifetime means in ASP.NET (and therefore when you can expect application start and end events to run). I assumed it would be when you run and stop the app in IIS, but I've read things that suggest it's related to number of requests.

• Python get raw_input but manually decide when string is done

  - by Jasie

  I want someone to type words in the console, and autocomplete from a list when they hit "tab" key. However, raw_input won't return a string until someone hits [Enter]. How do I read characters into a variable until the user hits [Enter]? *Note: I don't want to use import readline for autocompletion because of OS issues.

• CSS Doozie: Replacing BG Image on SELECT dropdown

  - by ToiletOverflow

  I need to be able to change the background-image property of a SELECT drop-down using JavaScript/CSS. We have been able to accomplish this in Firefox, but it doesn't appear to be supported at all in IE. From what I've read, IE won't support this. But I'm wondering if there's anything else I could try. Does anyone here have any recommendations?

• Is it bad practice to 'mix class and interfaces in the same package'?

  - by DerMike

  Hello, I just found something that I never heard of before and I do not agree with (by now). In an (upvoted and not further commented) answer I read "why to mix class and interfaces in the same package" So I wonder, if there are reasons to separate Interfaces and implementations in Java. I know that we are not obliged to have all implementations in the package of the interface, but is it (sometimes) wise to have none there? Regards Mike [;-)

• Starting a C++ project. Should I worry about freeing dynamic allocated memory?

  - by Luca Matteis

  I am pretty proficient with C, and freeing memory in C is a must. However, I'm starting a new C++ project, and I've heard some things about how you don't need to free memory using shared pointers and other things. Where should I read about this? Is this a valuable replacement for proper delete C++ functionality? How does it work?

• Why can't my function access a variable in an enclosing function?

  - by nailer

  I know about the LEGB rule. But a simple test of whether a function has read access to variables defined in an enclosing function doesn't seem to actually work. Ie: #!/usr/bin/env python2.4 '''Simple test of Python scoping rules''' def myfunction(): print 'Hope this works: '+myvariable def enclosing(): myvariable = 'ooh this worked' myfunction() if __name__ == '__main__': enclosing() Returns: NameError: global name 'myvariable' is not defined Am I doing something wrong? Is there more to it than the LEGB resolution order?

• Creating a "virtual" path (/bla) in Mac OS X and Linux that calls custom code

  - by Michael Stum

  Just something I'd like to play with, I would like to create a "virtual" file/directory in the File System of Linux or Mac OS X (Not sure if I can share the same code - does POSIX help?), for example /foo and then perform custom code when something is read or written to it. Similar how /dev/null allows for stuff like echo "Hello!" > /dev/null I don't care if it's in /dev, /proc or anywhere else, as said it's mainly something to play with...
