In this article, I will share some of my experience on installing NVIDIA driver and CUDA on Linux OS. Here I mainly use Ubuntu as example. Comments for CentOS/Fedora are also provided as much as I can.

This gist provides the learning-python3.ipynb notebook file, which can be viewed and edited in a Jupyter Notebook server to learn Python 3.

Ubuntu 12.04 Ruby on Rails Development Environment

I haven't set up an install guide for the latest ubuntu release, largely because the last set of instructions worked pretty closely with the latest and greatest Ubuntu, 12.04 Precise Pangolin, however when installing today, I found that there were enough differences in the way that I configure my setup to justify an update, so here it goes. Yes, I'm late to the party, but a quick google search didn't find anything that I felt was as complete for my requirements as my previous install guides, so here I go.

As always with my install guides, I have included here is just about everything you'll need (and then some) to get started with ruby on rails development with Ubuntu 12.04 as a platform. These are my settings and preferences, and this is certainly not the only way of doing things, so keep that in mind.

Step 1: Get the repos ready and run updates.

sudo apt-get update && sudo apt-get upgrade

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

	# This will use osd.5 as an example
	# ceph commands are expected to be run in the rook-toolbox
	1) disk fails
	2) remove disk from node
	3) mark out osd. `ceph osd out osd.5`
	4) remove from crush map. `ceph osd crush remove osd.5`
	5) delete caps. `ceph auth del osd.5`
	6) remove osd. `ceph osd rm osd.5`
	7) delete the deployment `kubectl delete deployment -n rook-ceph rook-ceph-osd-id-5`
	8) delete osd data dir on node `rm -rf /var/lib/rook/osd5`

	chrome.runtime.onConnect.addListener(port => {
	let recorder = null
	port.onMessage.addListener(msg => {
	console.log(msg);
	switch (msg.type) {

	console.log('Stopping recording')
	if (!port.recorderPlaying \|\| !recorder) {
