- It is now permissible to use urllib, urllib2 or httplib to make HTTP requests. (previously users were restricted to using urlfetch. Python programmers will be familiar w/ urllib, urllib2, and etc, and welcome this (they won't have to revise modules that use urllib2, as I did with my Blip API wrapper).
- The dreaded 10-second deadline for a request has been expanded to 30 seconds. While it's still not good form (actually, it's horrible form) to keep a user waiting for 30 seconds, this prevents errors if a website or API you are querying behind the scenes is slow.
- No more 'high CPU request' warnings. Note that just as George Carlin once observed that buying a 'safe car' doesn't excuse you from the responsibility of learning how to drive, it's also true that this is not Google's way of saying 'to hell with everything, write wasteful code now'
- The old 1MB limit on requests and responses was raised to 10MB
The good people of Blip were, as has always been my experience, quick to respond, and a fix is on the way, but it's not in place yet. As I mentioned in the previous post, the API is still private beta, so this is more a 'shame on me' matter, but as also mentioned in the previous post, this exercise is mostly an excuse to play around with Python and Google App Engine in order to learn more about it and generally 'keep brain from freezing', and as far as that goes, success was had. We'll re-visit it once Blip.fm has a fix in place.
For now, some good resources I've found for learning about the Google App Engine follow.
Web App Wednesday - Michael Bernstein puts out a new web app, plus the code, every week.
Giftag - BestBuy used Google App Engine to put together Giftag, a gift registry add-on for Firefox and Explorer. The blog is a good source of GAE info.
App Engine Fan - This guy has been experimenting with GAE since it was first released, recording the results of his efforts in this blog.
App Engine Samples - code samples from Google itself.
