get_mac_addr()

source code

Simply parses the output of ifconfig or ipconfig to estimate this machine's IP address. This is not at all reliable, but tends to work "well enough" for my own purposes.

retry_exp_backoff(initial_backoff, multiplier, func)

source code

Repeatedly invoke func until it succeeds (returns non-None), with exponentially growing backoff delay between each try.

Parameters:

initial_backoff (float) - The initial backoff.
multiplier (float) - The amount by which the backoff is multiplied on each failure.
func (function) - The zero-argument function to be invoked that returns True on success and False on failure.

Returns:

The result of the function
