Automount software RAID array in Ubuntu

I’ve spent ages trying to get automounting of a RAID array to work; and after many failings I now have it working, so I figured now would be a good time to document the process.

Now i’ll assume you have a working software RAID array (or a standard RAID Array) which you can manually mount.

Step 1 – Get the correct UUID

A lot of the guides to this tell you to find the UUID of the RAID array by using ‘mdadm –detail -scan’ – this is WRONG! It took me a while to find that the correct UUID for your array can be found by using the blkid command (blkid is a command-line utility to locate/print block device attributes):

blkid /dev/md127

Once you have the correct UUID you can move on…

ReSrc.it – Responsive images done right

The image you’re about to see is not residing on my server; it’s being served by ReSrc.it – a new cloud-based service which will actively deliver the optimum-sized image for your device. Don’t believe me? resize the browser window (so that the image size is reduced); reload the page and check out the source. you should be getting a new image every time the window is resized!

Sunset in Norfolk - ReSrced!

This is a massive leap forward for responsive design; it means that the right image, at the right resolution, at the right time can be delivered to your device. ISPs and Network providers are going to love this (as it saves on bandwidth); Web designers, photographers, content producers and anyone who works with images online have been crying out for this sort of a service since the whole ‘responsive web’ thing started.

I encourage you to check out their demo page (they have a load of image effects and switches to alter the loaded image) and if you think its awesomesauce then register for the Beta programme!

Working with Twitter Bootstrap on OS X

After messing with some of Twitter’s Bootstrap files locally, I decided it was time to get a build environment established on my Mac. It quickly became apparent that there wasn’t a whole lot of guidance on setting up the build environment in OS X; so i’ve posted my efforts here so that someone in my shoes can follow these steps:

Step 1: Install Node (and Node Package Manager)
Visit http://nodejs.org/ and download the installer for OS X (Lazylink: http://nodejs.org/dist/v0.8.12/node-v0.8.12.pkg)

Step 2: Clone and build Less.js
Install Less.js via folowing command (Assumes GIT CL Tools is installed):
git clone git://github.com/cloudhead/less.js.git

Next, go to the less.js directory, type: ‘make’.

Then copy the install directory to /usr/local/less.js

Add ‘export PATH=$HOME/local/less.js/bin:$PATH’ to ~/.bash_profile:

Open a terminal and type:

touch ~/.bash_profile; open ~/.bash_profile

Paste following in:

export PATH=$HOME/local/less.js/bin:$PATH

and save…

Step 3: Install Bootstrap Dependencies
Twitter Bootstrap depends on a number of packages; you can install all of them by using the following command with NPM:

npm install uglify-js less jshint recess -g

Step 4: clone and make Twitter Bootstrap
Clone Bootstrap:
git clone git://github.com/twitter/bootstrap.git

Go to the bootstrap directory, type: ‘make’.
Built files are output in the ‘docs’ directory…

Enjoy!
