NASCAR may be dominated by gas-guzzling racers, but its pace car this weekend is decidedly kinder to the environment. The motorsport league's Sprint Cup race in Richmond on the 26th (delayed from the 25th due to rain) has Toyota's hydrogen-powered Mirai as its pace car -- the first time a fuel cell car has had that distinction at a NASCAR event. This is largely a publicity stunt to build up hype for the Mirai's Californian launch later this year, but it shows that hydrogen cars have the performance needed to keep up with stock cars during yellow flags. The real challenge will be getting the actual competitors to go green. While there have been hydrogen-fueled race cars before, the odds are that NASCAR and its fans aren't eager to abandon roaring V8s any time soon.

Yup, after what seemed like an eternity, it looks to be that the iPhone slowdown fiasco is finally over. This only means that developers can use this moment as an opportunity to ramp up on app development and take advantage of the enhanced speed and feature upgrades of the new operating system. If you want to get in on the frenzy, these training bundles will help you get familiarized with iOS 12 update so you can start writing your own apps: Led by top-rated instructor Rob Percival, this 167-lecture course will guide you through the essentials like Swift 4 and Xcode 10 and help you develop practical skills by letting you build
