I wish my university would start something like this for their students.

Coursera – a free online university.

I thought I’d quickly share something I came across a few weeks ago. Coursera is a free online university that offeres various university quality courses online for free. Each course has about 2+ hours of video lectures per week with weekly quizes and a few assignments. So far I’ve been enjoying the courses I’ve enrolled in however I won’t be planning to finish then by the course end date due because I don’t have enough time and I’m already studying. So if you have some spare time it’s worth a look.

Pizza Vending Machine

Came across this yesterday on reddit, a vending machine that make pizzas in 3 minutes.

For about $5 a pizza the ‘Lets Pizza’ vending machine you see each process of you pizza been made (forming dough, toppings, cooking) until three minutes later you can retrieve your freshly made pizza. Have a look at the promo video.

Also if you (like me) are more interested in the internals of how the machine works check out this video of the machine been put together. (Skip to around 5:35)
