  - by Geo

  I have a form where someone can create a new user. I'd like to add some AJAX to check if a username is taken, as soon as the input field loses focus. I'm not really sure how to go about this, as this could pave the way to bruteforce attack, since you could check for any username and see whether or not it exists. Any suggestions?

  - by Raju

  A lot of web applications having a 3 tier architecture are doing all the processing in the app server and use the database for persistence just to have database independence. After paying a huge amount for a database, doing all the processing including batch at the app server and not using the power of the database seems to be a waste. I have a difficulty in convincing people that we need to use best of both worlds.

• Looping through a directory on the web and displaying its contents (files and other directories) via

  - by al jaffe

  In the same vein as http://stackoverflow.com/questions/2593399/process-a-set-of-files-from-a-source-directory-to-a-destination-directory-in-pyth I'm wondering if it is possible to create a function that when given a web directory it will list out the files in said directory. Something like... files[] for file in urllib.listdir(dir): if file.isdir: # handle this as directory else: # handle as file I assume I would need to use the urllib library, but there doesn't seem to be an easy way of doing this, that I've seen at least.
