When I start "recover node <storage_node_name>" message of type QUEUE_ID_RECOVERY_NODE seems to be
blocking processing of other messages (mainly, QUEUE_ID_PER_OBJECT ones).

I tried to visualize message processing using StatsD:
http://ns2.1888.spb.ru/2015-02-24-024731_1366x768_scrot.png
A graph at the lower right corner depicts calls to
handle_call({consume, ?QUEUE_ID_RECOVERY_NODE, MessageBin}).
It is my understanding that recover_node_callback(Node) should generate a lot
of QUEUE_TYPE_PER_OBJECT messages synchronously for a single QUEUE_ID_RECOVERY_NODE
message but the graph shows that QUEUE_ID_RECOVERY_NODE messages are constantly processed.

groupby and countby for python

Python has the standard methods for applying functions over iterables, viz. map, filter, and reduce.

For example, we can use filter to filter some numbers by some criterion:

even = lambda x: x % 2 is 0
odd  = lambda x: not even(x)
data = [1, 2, 3, 4]

Moved

Now located at https://github.com/JeffPaine/beautiful_idiomatic_python.

Why it was moved

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!

On Mac OS (host):

Shutdown your VM and do:

VirtualBox > Settings > Network > Add (you will get vboxnet0)

On a terminal ifconfig will show you new interface vboxnet0

VM's Settings > System > check "Enable I/O APIC." VM's Settings > Network > Adapter 2 > host-only vboxnet0
