Things I learned lately 11 May

• California became the first state in the US to require all new homes to be built with rooftop solar panels. The California Energy Commission voted unanimously in favour of the rule. Starting January 2020 any new home that's 3 stories or less, will need to include energy-harvesting solar panels on top, unless they are in the shade or the roof is too tiny.
• By 2020, it is estimated that Canada's marijuana industry will be bigger than its alcohol industry, possibly $6.5 billion.
• 53% of polled Canadians said it's not necessary for couples to tie the knot to spend their lives together, and 1 in 6 said they're not interested in the marriage at all.
• Google is working on visual positioning for Google Maps (see right). Using AI, Maps will be able to tell exactly where you are using what your phone's camera sees and help guide you to your destination while walking. Using augmented reality, Maps will also superimpose points of interest onto the image you see on the screen.
• Google Photos will soon be able to automatically add colour to old black and white photos.
• Americans got 3.4 billion spam calls in April.
• 250 years ago, 1/3 of children in the world's richest countries didn't live to see their 5th birthday.
