The True Purpose of Solitaire, Minesweeper, and FreeCell

If you haven't ever played Solitaire, Minesweeper, Hearts or FreeCell, it's safe to say you're in the minority. These simple Windows games have probably caused more lost worker hours than anything short of a worldwide coffee shortage. Whichever one was your favorite, the temptation to take just one more go at beating them—to get a faster time or a better score—was hard to ignore.

But as fun as these games were, they weren't actually designed for entertainment. At least not in their Windows incarnations.

The oldest of the four, Microsoft Solitaire, was first added to Windows 3.0 in 1990. Although the game (sometimes called "Patience") has existed since the late 1700s, this digital version seemed to be demonstrating that in the future we would no longer require a physical deck to play simple card games. But that's not what it was doing at all. Its real aim was far more modest: it was teaching mouse-fluency by stealth.

The intention was that Solitaire would get a generation of computer users still most familiar with a command-line input to teach themselves how to drag and drop, without realizing that's what they were doing. The fact that we're still dragging and dropping today suggests that it worked rather well.

Minesweeper, too, has a similar place in technological culture. The numbers-based logic puzzle has roots in the mainframe gaming scene of the 1960s and 1970s, where a version called "Cube" by Jerimac Ratliff became incredibly popular. Decades later, in 1992, the Microsoft version Minesweeper was introduced to Windows 3.1—not to demonstrate that Windows was an adept gaming operating system, but to make the idea of left and right clicking second nature for Windows users, and to foster speed and precision in mouse movement.

If you needed any proof that this isn't a coincidence, look at another Microsoft card game: Hearts. It was introduced with 1992's Windows for Workgroups 3.1—the first network-ready version of Windows—and used Microsoft's new NetDDE technology to communicate with other Hearts clients on a local network. Again, this wasn't just a card game. It was a way to get people interested in (and hopefully impressed by) the networking capabilities of their new system.

And finally, there's FreeCell. Released for Windows 3.1 as part of the Microsoft Entertainment Pack Volume 2, FreeCell was bundled with the Win32s package that allowed 32-bit applications to run on the 16-bit Windows 3.1. Its purpose was actually to test the 32-bit thunking layer (a data processing subsystem), which had been introduced as part of Win32s. If the thunking layer was improperly installed, FreeCell wouldn't run. So what you thought was a game was actually a stealth test of software systems.

Of course, none of this explains why those games persisted once their remit was fulfilled. The answer is simple: people had too much fun with them. Any time Microsoft tried to remove the games from a release of Windows, testers went crazy. Eventually, in 2012, Microsoft released a version, Windows 8, without any of the games. Users could download the Solitaire Collection and Minesweeper separately, but you had to pay extra to play without ads.

However, with this year's release of Windows 10, Microsoft has at least brought back Solitaire. If you go looking for the others in your search bar, you'll instead be shown search results from the Windows Store where you can download the latest versions. And maybe that's intentional, because what better motivation do you need to learn how to use the Windows Store than to get your hands on your favorite games? Maybe they're still teaching by stealth, even after all these years.

Undersea Internet Cables Could Be Key to the Future of Earthquake Detection

Considering that 70 percent of the planet is covered by oceans, we don't have all that many underwater earthquake sensors. Though there's plenty of seismic activity that happens out in the middle of the ocean, most detection equipment is located on land, with the exception of a few offshore sensor projects in Japan, the U.S., and Canada.

To get better earthquake data for tremors and quakes that happen far from existing sensors, a group of scientists in the UK, Italy, and Malta suggest turning to the internet. As Science News reports, the fiber-optic cables already laid down to carry communication between continents could be repurposed as seismic sensors with the help of lasers.

The new study, detailed in a recent issue of Science, proposes beaming a laser into one end of the optical fiber, then measuring how that light changes. When the cable is disturbed by seismic shaking, the light will change.

This method, which the researchers tested during earthquakes in Italy, New Zealand, Japan, and Mexico, would allow scientists to use data from multiple undersea cables to both detect and measure earthquake activity, including pinpointing the epicenter and estimating the magnitude. They were able to sense quakes in New Zealand and Japan from a land-based fiber-optic cable in England, and measure an earthquake in the Malta Sea from an undersea cable running between Malta and Sicily that was located more than 50 miles away from the epicenter.

Seismic sensors installed on the sea floor are expensive, but they can save lives: During the deadly Japanese earthquake in 2011, the country's extensive early-warning system, including underwater sensors, was able to alert people in Tokyo of the quake 90 seconds before the shaking started.

Using existing cable links that run across the ocean floor would allow scientists to collect data on earthquakes that start in the middle of the ocean that are too weak to register on land-based seismic sensors. The fact that hundreds of thousands of miles of these cables already crisscross the globe makes this method far, far cheaper to implement than installing brand-new seismic sensors at the bottom of the ocean, giving scientists potential access to data on earthquake activity throughout the world, rather than only from the select places that already have offshore sensors installed.

The researchers haven't yet studied how the laser method works on the long fiber-optic cables that run between continents, so it's not ready for the big leagues yet. But eventually, it could help bolster tsunami detection, monitor earthquakes in remote areas like the Arctic, and more.

AI Remade Old Music Videos, and You'll Never See 'Sabotage' the Same Way Again

From rewriting Harry Potter scripts to naming guinea pigs, getting artificial intelligence to do humans' bidding is the latest trend in internet entertainment. Now, we can all enjoy AI remakes of iconic music videos such as "Sabotage" by the Beastie Boys, "Total Eclipse of the Heart" by Bonnie Tyler, and "Take On Me" by A-Ha.

As spotted by Co.Design, these "neural remakes" were uploaded to YouTube by Mario Klingemann, an artist-in-residence at Google Arts. The AI model he created is capable of analyzing a music video and then creating its own version using similar shots lifted from a database of publicly available footage. The results are then uploaded side-by-side with the original video, with no human editing necessary.

"Sabotage," a spoof on '70s-era cop movies, might be the AI's "most effective visual match," at least by Co.Design's estimate. The AI model found accurate matches for vintage cars and foot chases—and even when it wasn't spot on, the dated clips still mesh well with the vintage feel of the original video. Check it out for yourself:

"Total Eclipse of the Heart," a bizarre video to begin with, spawned some interesting parallels when it was fed through the AI model. Jesus makes a few appearances in the AI version, as does a space shuttle launch and what appear to be Spartan warriors.

And finally, 11 years after the original rickroll, there's now a new way to annoy your friends: the AI version of Rick Astley's "Never Gonna Give You Up," featuring John F. Kennedy and Jesus, yet again. This one is presented on its own in full-screen rather than split-screen, but you can rewatch the original video here.
