HTTP response was too large

In case you run into this error:

HTTP response was too large: 3410251. The limit is: 1048576.

(The number 3410251 above might vary completely arbitrarily)

Solutions like this won't help you, because you know for a fact that you have no file that large or anything that could reasonably cause it, then it might be because you have a maximum recursion depth reached error. This causes an enourmous stack trace which will exceed Google App Engines maxiumum response length (1MB). Try sweeping your code for any place where infinite recursion might occur.

Serving static files with Django and AWS - going fast on a budget

Found this little gem linked from TechCrunch today.

Serving static files with Django and AWS - going fast on a budget

Speed matters. When Google tried adding 20 additional results to their search pages, traffic dropped by 20%. The reason? Page generation took an extra .5 seconds. This article will show how Eventseer utilizes an often overlooked way of improving the responsiveness of a web application: Pre-generating and serving static files instead of dynamic pages.

I've been way too hard at work on SlurpBOX to notice, but the fine App Engine Helper for Django guys have made a new release! See the top item in the release notes? I found that bug! :P Go download.
