Hacked Rotary Phone Demonstrates How the Internet Works

Untangling the inner workings of the internet gets complicated fast, partly because the World Wide Web isn’t a single entity. Rather, it’s a vast network of networks in communication with one another. To demonstrate this complex process at work, a group of students from Copenhagen reduced it to something most people are familiar with: a rotary telephone.

As Co.Design reports, the Internet Phone looks like an old-fashioned telephone with a rotary dial, but students at the Copenhagen Institute of Interaction Design have modified it to function like a web browser. To use it, callers dial the IP address of whichever website they wish to visit. When the call is answered, a voice reads the text aloud as it would appear on the webpage.

If a caller wants to hear the raw HTML, they can switch the phone to “developer” mode. There’s also an “article” option for skipping irrelevant content and a “history” mode for redialing the last five IP addresses that were called.

It may be hard to connect the act of calling a website on a rotary phone to opening a site on your smartphone, but the two aren’t that far apart. The students write in the project description:

“Each step in the user experience is comparable to the process that a browser takes when retrieving a website. Looking up the IP addresses in a phone book is similar to how a browser gets an IP address from DNS (Domain Name System) directories. Dialing the twelve digits and waiting for the phone to retrieve the HTML content mimic how a browser requests data from servers. The voice-to-speech reading of the website is comparable to how a browser translates HTML and CSS code into human understandable content.”

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.
