400 or 403 for invalid form submission?

Conclusion: use 400

The Spec ( http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html )

I spend a few hours banging my head against this, and finally got it to work. There may be a better way, but I couldn't find it.

Ardiuno-Makefile instructions for OS X

Examples for Arduino Nano V3.0.

First, install the Arduino software from arduino.cc as usual, as well as the FTDI driver (if needed for your board). https://github.com/mjoldfield/Arduino-Makefile

You'll need a couple of Perl modules:

Since Django 1.5.5, CSRF tokens are rotated on login. That makes it trivial to trigger a CSRF error in the following way:

Open your app's login page in two different browser tabs.
Log in using tab 1
Log in using tab 2

The CSRF token sent along with the second login attempt (in a cookie) won't match the token that was embedded in the form, and so a CSRF error will be displayed.

It could be argued that the above is an odd/contrived thing to do, and so displaying a CSRF error here isn't too bad. Fine. But there's another, more subtle, way to trigger the same thing:
