A couple of people have emailed in to ask what the answer was to our competition brain teaser this year...
So, this year we went for something a little less PHP-specific.
About 30% of entrants got this one right - so well done to all of you!
The very first step with this challenge is recognising base64 encoded data when you see it - which is pretty easy if you've ever worked with email content or the CSS embedded image data-uri feature.

Decoding this second string give us some binary output - but with one give-away human-readable prefix:
So, writing the output of the last decode to a gif file completes the process:
And finally, the magic phrase:
Which is a nod to the competition prize - a brand new MacBook Air 13".
