EdX: Take a free course
edX is a massive open online course (MOCC) platform launched in 2012. Beginning with a single free course in electronics, edX has expanded its free offerings to include medical courses, physics, law, ethics and beyond.
Established by Harvard and MIT, the non-profit allows students to register before undertaking courses through pre-recorded lectures, forums and virtual labs.
Make good use of your 404 page
If you are a website owner with a bland 404 page, why not put it to good social use?
This is the concept behind the NotFound project, which gives website masters an application that automatically publishes a picture of a missing child on every 'not found' page of a website.

Check out the plane's interior for your next flight
Sitting for hours in a cramped metal tube isn't generally much fun, unless you have pockets deep enough to hang out in first class. If you'd like a more comprehensive look at the plane you've booked yourself on, then Seatguru can give you airline seat maps, flight updates and photos.
In addition, previous fliers are able to comment on particular craft or flights.
One of the coolest features available on the website is a Beta comparison service between different economy flights. The prices vary -- as does seat width and leg room.
