A great explanation of real time bidding and how your personal information does get shared by google (and many others) with thousands of third-parties, some in China and Russia. Whatever sneaky language they use to reassure you, this is the reality of the online advertising world.
Two women reminisce about their teenage years in the 1890s. They were obviously better off than many of their counterparts of the day but it's still quite fascinating to get first-person accounts that go so far back. I'm also impressed by one woman's cycling endurance. London to Brighton and back on what was effectively a fixed-gear bike is quite something.
