Between the years of 1825 and 1843 , through floods and financial failures, Marc Isambard Brunel and his son dug a tunnel under London’s Thames River. Our ambitions have grown since then, but the technology we use still bears a striking resemblance to Brunel’s shipworm-inspired device.

In this article, I look at some of the worlds most breathtaking underwater tunnels and delve into how they were constructed.

How do you build an underwater tunnel?

Cloudy With a Chance of Hacking: Remote File Access

In the internet’s early days, bottom-of-the-barrel bauds would choke on anything bigger than a  byte-sized file. Today, bandwidth has opened wide enough to gulp down gigabyte-sized games and stream movies, enabling companies to provide  access to your media and work files anywhere and any time you want it. If you are curious about virtual private networks, remote file access and cloud services, here is a nice friendly article that breaks it all down for you and includes a brief tour of the more popular options available.

Baseball seems like a fairly simple game . . . until you try to explain it to someone. Even ignoring the infield-fly rule, there’s a surprising amount of complexity packed into a few pages of guidelines.

Case in point: baseball’s part-rule, part-event, part quantum physics experiment, the fourth out. Most fans have never heard of it, although they’ve probably seen it in action. But not understanding the ins-and-outs of this technical twist can cost games.

What is the fourth out?

The Art of the Bunt: Deconstructing Dickey’s “Tricky Hit”

Bunting, says Bill James of Sabermetrics fame, is “the only play in baseball that both sides applaud.” But years ago, every player – even sluggers like Babe Ruth and Mickey Mantle – used bunting as a fundamental part of the game, and some coaches still prefer the bankable bunt when it comes to advancing runners, especially when a weak hitter steps to the plate.

Whatever your viewpoint, there’s little doubt that bunting is an art. Read on for the ins-and-outs of this venerable and controversial technique.
