There was a command for rate per second. Could anybody help me?

Every server will happily fill in the blank for you, saving you from figuring out what JID your client has. | 1 | 1 | 0 | Okay, this isn't a question. All the examples of wokkel and twisted I have seen do not properly observe generated resources in the JID.
Google talk clients built using wokkel/twisted generally break because they do not set the full JID on responses, resulting in (very hidden, low level) errors like:

If a dict was hashed, its hash would change as you changed its contents. | 1 | 29 | 0 | I mean why cant we put key of dict as dict?
that means we can't have dictionary having key as another dictionary... | why dict objects are unhashable in python? | 1.2 | 0 | 0 | 31,172 |
