AI Thread Summary
The user is experiencing a version mismatch between Python (2.7.3) and IPython (2.2.0) while attempting to open the IPython notebook, resulting in an error related to the I/O handler. The error traceback indicates a KeyError in the event loop. There is a suggestion to resolve the issue by downgrading to IPython version 0.12.1, but the user is unsure how to perform this downgrade. A link to a Stack Overflow discussion is provided for further guidance on starting the IPython notebook.

Hello,

By typing "python -V" i get 2.7.3 and by typing "ipython -V" i get 2.2.0.

Now when i am trying to open "ipython notebook" i get the following error:

ERROR:root:Exception in I/O handler for fd 3
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/zmq/eventloop/ioloop.py", line 330, in start
self._handlers[fd](fd, events)
KeyError: 3

Anyone know what is going on??
can i fix it by switching to the 0.12.1 version of ipython ... but i don't know how to do this...

Thread 'Is this public key encryption?'

I've tried to intuit public key encryption but never quite managed. But this seems to wrap it up in a bow. This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher. Is this how PKE works? No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.
