urllib.urlopen(url).read() ?
what if it's a huge file?

what if it's the URL to your private,

Debugging in
development rocks!
django_debug_toolbar = awesome
assert False = instant useful 500 page
import pdb; pdb.set_trace() adds a
command line debugger to your running
application!

django_instrumented
(Unreleased) code I wrote for Lanyrd
Collects various runtime stats about the
current request, stashes a profile JSON in
memcached
Writes out the profile UUID as part of the
HTML
A bookmarklet to view the profile

Django improvements
DEBUG as a global setting is an anti-
pattern
More low-level hooks for measuring,
well, pretty much everything
Live profiling tools (as a third-party
product)
46. Lanyrd.com
Deploy DB changes
separately from code changes
Make backwards compatible schema
changes
We deploy code to a none-web server
just so we can run "./manage.py migrate"
(you are using South, right?)
Use symlinks for instant rollback to
previous code
47. Lanyrd.com
Read-only mode
If you can flip your site in to read-only mode,
upgrades become a lot easier
Flip to read only mode
Replicate DB to a new machine
Run migrations, then test
Switch app servers to new database
(On EC2, fire up an entire new web cluster)
