You’re Doing It Wrong - ACM Queue
The Bike Shed June 11, 2010 Volume 8, issue 6 PDF You're Doing It Wrong Think you've mastered the art of server performance? Think again.

Python logging from multiple processes | Huy Nguyen
Had a rough day today. I just wanted a log. Not just any log mind you, but one that could handle writes from multiple processes running at the same time. A naive me would have put python’s basic log handler within each process and then watch as each of the processes crash and burn because of conflicting disk write access. But I’ve learned from my past lessons – now I use the python SocketHandler f
