First ssh in to pi and cd in to Downloads directory.

$ cd ~/Downloads

Next you need to download the nodejs tar. Checkout the version you desire make sure you download the the version with the last string ending ‘linux-armv6l.tar.gz’. Raspberry Pi Zero support only ARMv6.

$ wget

Once downloaded cd in to usr/local

cd /usr/local

Extract tar here

sudo tar xzvf ~/Downloads/node-v6.10.3-linux-armv6l.tar.gz --strip=1

And finally remove default npm, node and nodejs.

sudo apt-get remove --purge npm node nodejs

Now check the version

$node -v && npm -v

Only recently I needed to access my iMac GUI whilst I was away aboard. I’ve always ssh to my iMac being a geek. But for this particular occasion I needed to demo things on my iMac.
Anyways I did a little research and here are my findings and conclusion.

Like I said I’ve always ssh in to my box via VPN, takes awhile to setup if you know what you’re doing, but very useful if you want connect to your home network whilst your in another country.

VNC Viewer

If you have VPN the best app to use is VNC viewer and this is free.

On your Mac you first need to download VNC Connect client. See step by step instructions here.

Next download VNC Viewer on you iPad/iPhone. If you sign up and add your mac details and your way!

Usability is ok, I find it a bit slow compare to the other Remote Desktops apps. I feel it’s very graphic heavy and may eat in to your data plan.


Teamviewer is free for personal use only… But you if you have several machine you like to connect to, you are advice to purchase a licence, which I think is fair.

Teamviewer is very simple to install. Again it is best to sign up and user your login to your both desktop and mobile apps:
Desktop – Teamviewer client
iPad/iPhone – Teamviewer app

By far, I think the usability on the iPad/iPhone is very simple compare to all the rest for Remote Desktops apps. The app is optimise to your reduces your mobile bandwidth.

Google Chrome Remote desktop

Google is new to the game. I know Google had done similar in the past using their web browser, but this did not fly too well as it was very sluggish. Chrome Remote Desktop is the new and improve version. Works very well. You do not need VPN enable. You can access again on your iPad/iPhone.

The navigation works very similar to VNC viewer. The app is also optimised to your reduces your mobile bandwidth.

Apple Screenshare

Apple Screenshare is pretty recent with the new macOS Sierra. Screenshare is already intergated to the system. all you need to do is make use you are signed in to iMessage and thats it.

Search Screenshare by holding down Command and spacebar and type in ‘Screenshare’. put in the ip address if you have VPN and your in.

The other way is by sharing your screen or taking control of your friend/family desktop is by going to iMessage select the your user message and click on the ‘i’ icon and you will see the overlapping windows icon. Click on this and you will be presented the two options. Control or view.

Is is simple Remote desktop app which is web based.

To fix this you need to edit .bash_profile. Run these commands in terminal

sudo nano ~/.bash_profile

Add the following line

export PATH="/Applications/MAMP/Library/bin:/Applications/MAMP/bin/php/php5.5.10/bin:$PATH"

Exit and save… next run

source ~/.bash_profile

Restart machine…

Job DONE! to test drush is working correctly

I’ve been using Compass for awhile now… the best tool to compile your SASS. Below are some plugins I use to help create that perfect website.

To get started you first need to install ‘Ruby’ and ‘Compass’ and the below plugins… So when you start writing up your SASS you can call in Mixins from any of those plugins. The rest is magic!!!

Insert these to your ‘config.rb’ file.

# Require any additional compass plugins here.

require ‘compass-recipes’
require ‘compass-css-arrow’
require ‘breakpoint’
require ‘susy’
require ‘rgbapng’
require ‘compass-normalize’
require ‘animate-sass’
require ‘toolkit’
require ‘sassy-buttons’
require ‘font-awesome-sass’
//require ‘bootstrap-sass’ // Some of you would like to use Bootstrap framework


Add these to your ‘_layout.scss’ file.

//Compass Mixins
@import ‘compass’;
@import ‘compass/reset’;
@import ‘breakpoint’;
@import ‘compass-css-arrow’;
@import ‘rgbapng’;
@import ‘bootstrap’;
@import ‘toolkit’;
@import ‘sassy-buttons’;
@import ‘font-awesome’;
@import ‘susy’;
@import ‘toolkit/fluid-media’;
@import ‘toolkit/nested-context’;
@import ‘animate/shared’;
@import ‘animate/animations/attention-seekers’;
@import ‘animate/animations/flippers’;
@import ‘animate/animations/fading-entrances’;
@import ‘recipes/effect/ribbon’;

Hi guys, if you are looking for a quick site build from scratch, i would advice to download Twitter Bootstrap or Skeleton to help you get on your way. You do not need to be an expert in html or css, but you need to have some knowledge to take full advantage. Both Twitter Bootstrap and Skeleton front-end frameworks works are great, but I think Twitter Bootstrap has the upper-hand, in terms of use of JavaScript, JQuery libraries and icons. Both frameworks has the 960 grid, responsive and fluid system.

See links below and let me know what you think?
