Created May 18, 2012 07:51
Queue based consumer/producer.
;; This example shows how to create a single producer and multiple consumers.
;; Each consumer will receive the message. I'm not sure if internally it's handled in a round-robin manner,
;; but when queue does not listen for messages (e.q. it's processing them), it won't receive one.
;;
;; In order to run it, use:
;;
;; lein2 run --mode consumer

;; And in other window:

fundon / python-vs-go.mdown
Created April 16, 2012 07:47 — forked from sma/python-vs-go.mdown
Ich versuche Go zu lernen, indem ich das Grundgerüst für einen Python-Interpreter schreibe

Python vs. Go

Bekanntlich kann CPython Code nicht parallel in Betriebssystem-Threads ausführen. Es gibt den Global Interpreter Lock (GIL), der verhindert, dass dies passiert. Auf einem Computer mit mehr als einer CPU (dem Standard heutzutage), kämpfen alle paar Millisekunden die CPUs um den GIL, was dazu führt, dass die Laufzeit von CPython in diesem Fall deutlich schlechter als das theoretische Maximum ist.

Dieses Python-Programm braucht auf meinem Rechner etwa 9,5s:

def count_down(n):
    while n > 0:

n -= 1
