INSTALL: Newly necessary way to snap and share

Color is a deceptively simple photo-sharing app that could be the one none of us realised we needed.

Take a picture and it is shared with everyone within a 50 metre radius.

You can create temporary groups of friends when you are out on the town with them but there are no friends and followers in Color so your snaps are shared with all other users in the space radius.

If you think it's a silly idea just remember Sequoia Capital has invested more in Color before its launch than it poured into Google.

Your cookies for more bargains

CLEAR:Ever regret not booking those bargain flights the first time you saw them?

Andrew Sampson, Stephen Fry's business partner in his digital efforts, posted to Twitter this week that Ryanair flights he viewed for £123 (€140) had increased to £237 the following day.

But being a little tech savvy Sampson cleared his cookies (search in your browser's help settings) and the fare reverted back to the original price of £123.

If you are having a similar experience buying flights online it's got to be worth a try.

Difficult or not, follow your convictions

READ:Bill Liao, the Australian-born serial entrepreneur, who now divides his time between Ireland and Switzerland, features heavily in this post from Om Malik exhorting entrepreneurs to have the courage to follow their convictions.

Malik met Liao at a lunch meeting in San Francisco – after which Liao was planning to head home to Ireland on trains, container ships, buses and whatever other green transport is available, as part of his commitment to the planet.

As Malik puts it, Liao "is one of those entrepreneurs who marches to his own drummer".
