I have a secondary window (a sheet) for a dialog controlled by a secondard WindowController. For some reason, the actions never get called in NSObject subclass after the sheet is displayed.

It's not always the same error, but differe...

For each line, I'll pass it to the predicate func, if it returns...
My script.py creates a temporary file in the same dir as the script. When running it: python script.py it works just file but it doesn't work when you run: python /path/to/script.py That's because I'm using a relative path to my temp file in script.py rather than an absolute one. The problem is that I don't know in which path it ...

Hi all, I'm looking for a bit of help with a regex in python and google is failing me. Basically I'm searching some html and there is a certain type of table I'm searching for, specifically any table that includes a background tag in it (i.e. BGCOLOR).

Hello, In GAE, you can say users.get_current_user() to get the currently logged-in user implicit to the current request. This works even if multiple requests are being processed simultaneously -- the users module is somehow aware of which request the get_current_user function is being called on behalf of. I took a look into the code of ...

My brain feels slow today. I'm writing pre/post/invariants in Python using decorators. Currently, I need each call to specify the locals and globals for context, and this feels ugly. Is there a way to get the locals and globals from the decorator application level even though it's an arbitrary depth. That is, I'm trying to make ...
TinyMCE is working just fine, all except for the popup windows. They come up blank, and after a little bit of Google searching, apparently it has something to do with cross domain errors with Firefox and Django. I tried using document.domain, but I have a feeling that it doesn't work when you're using the Django development server (http:...
Hi all, I'd like to start by asking for your opinion on how I should tackle this task, instead of simply how to structure my code.
