UFW

I use Ubuntu’s Uncomplicated firewall because it is available on Ubuntu and it's very simple.

Install UFW

if ufw is not installed by default be sure to install it first.

I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.

As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:

group browsers {
    cpu {
#       Set the relative share of CPU resources equal to 25%
        cpu.shares = "256";
 }

This module provides a simple WSGI profiler middleware for finding 
bottlenecks in web application. It uses the profile or cProfile 
module to do the profiling and writes the stats to the stream provided

To use, run `flask_profiler.py` instead of `app.py`

# The difference between the `sep` and `collapse` arguments
# in paste can be thought of like this:
# 
# paste can accept multiple *vectors* as input, and will
# concatenate the ith entries of each vector pairwise 
# (or tuplewise), if it can.
# 
# When you pass paste multiple vectors, sep defines what
# separates the entries in those tuple-wise concatenations.
