Ubuntu on Acer Aspire Switch

The problem

What's the problem with this tablet? Why can't I just insert the USB and mash F12 until it boots? The tablet is made to run Windows 8.1 and Windows 8.1 only. Some absolute genius at Acer decided to put a 32-bit UEFI on a 64-bit system, which no reasonable Linux distro supports out-of-the-box.

NOTE: This guide focuses on installing Ubuntu alongside Windows. If you're trying to replace Windows, then I assume you know enough about Linux to know which parts to change.

What works:

Installing Python 2.7 on Centos 6.5

Centos 6.* comes with Python 2.6, but we can't just replace it with v2.7 because it's used by the OS internally (apparently) so you will need to install v2.7 (or 3.x, for that matter) along with it. Fortunately, CentOS made this quite painless with their Software Collections Repository

sudo yum update # update yum
sudo yum install centos-release-scl # install SCL 
sudo yum install python27 # install Python 2.7

To use it, you essentially spawn another shell (or script) while enabling the newer version of Python:

# Ubuntu 14.04 don't have nsenter - the straight forward way required me to install build tools and etc.
# I preferred to keep the system clean and install nsenter in a container and then copy the command to the host
# Note - its also possible to run nsenter from a container (didn't tried) https://github.com/jpetazzo/nsenter

# start a container
docker run --name nsenter -it ubuntu:14.04 bash

## in the docker
apt-get update
apt-get install git build-essential libncurses5-dev libslang2-dev gettext zlib1g-dev libselinux1-dev debhelper lsb-release pkg-config po-debconf autoconf automake autopoint libtool

Conditions

Two Storm supervisors running in a 3-node configuration: one "head" node (nimbus) and two worker nodes. Each supervisor node runs a supervisor under supervision.

Topology

Multi-lang topology using Python and our streamparse library. Works fine when running on a single machine. Spout reads off Kafka and inserts tuples into
