Huge, detailed, brightly coloured images flickered across the screen, illuminating the whole room like the lights off one of those laser light disco balls at the skating rink. My brother's eyes bulged. "It's too much," he gasped as I scrambled for the remote just to pause the vivid assault on our eyeballs. He'd just come over to help me set up the enormous 65-inch Q9 television from Samsung, and after adding on the feet — which required laying it across my entire bed, and then wrestling it onto the stand (it weighs over 27kg), we sat down to watch one of my favourite test shows Sense8.

The show is great for testing TVs because it's bright and colourful with a wide array of skin tones that can end up looking orange or muddy on a cheaper TV. I wanted to know if a super expensive set like the Q9 was ever worth it when it's totally possible to get great TVs for $1500 or less. As soon as I hit play I had my answer — a pricey TV can be a real game changer.

Uber has rightfully taken heat for its past privacy overreaches: Tracking riders after they get dropped off, tracking Lyft drivers, tracking and circumventing law enforcement, tracking critical journalists. A lot of tracking in situations where people expected not to be tracked!

It's now clear that wasn't the case, and it appears the attackers may have been targeting tech firms for the purposes of industrial espionage.

Earlier this month, President Donald Trump nominated Jim Bridenstine — a Republican representative in Oklahoma — as NASA's new leader. Like most people in this administration, Bridenstine actively supports ideas antithetical to his (soon-to-be) agency: he's an avid supporter of private space companies and denies that human activity impacts climate change. Now, Bridenstine wants to take a seemingly good idea — studying Mars' weather — and turn it into a misleading talking point about climate change on Earth. Probably.
