How a Wall of Lava Lamps Makes the Web a Safer Place

A secure internet network relies on bits of data that hackers can’t predict: in other words, random numbers. Randomization is an essential part of every encryption service, but spitting out a meaningless stream of digits isn't as easy as it sounds. Computerized random number generators depend on code, which means it's possible for outside forces to anticipate their output. So instead of turning to high-tech algorithms, one digital security service takes a retro approach to the problem.

As YouTube personality Tom Scott reports in a recent video, the San Francisco headquarters of Cloudflare is home to a wall of lava lamps. Those groovy accessories play a crucial role when it comes to protecting web activity. The floating, liquid wax inside each of them dictates the numbers that make up encryption codes. Cloudflare collects this data by filming the lamps from a wall-mounted camera.

Unlike computer programs, lava lamps act in a way that's impossible to predict. They're not the only secure way to generate randomness (tools used by other Cloudflare offices include a "chaotic pendulum" and a radioactive source), but they may be the prettiest to look at.

How to Perform the Star Wars Theme—On Calculators

The iconic Star Wars theme has been recreated with glass harps, theremins, and even cat meows. Now, Laughing Squid reports that the team over at YouTube channel It’s a small world have created a version that can be played on calculators.

The channel’s math-related music videos feature covers of popular songs like Luis Fonsi’s "Despacito," Ed Sheeran’s "Shape of You," and the Pirates of the Caribbean theme, all of which are performed on two or more calculators. The Star Wars theme, though, is played across five devices, positioned together into a makeshift keyboard of sorts.

The video begins with a math-musician who transcribes number combinations into notes. Then, they break into an elaborate practice chord sequence on two, and then four, calculators. Once they’re all warmed up, they begin playing the epic opening song we all know and love, which you can hear for yourself in all its electronic glory below.

This Cuddly Robot Is Designed to Lull You to Sleep

For people seeking all the benefits of a human sleeping companion without the human part, there’s a new Kickstarter-backed product. As Mashable reports, Somnox, the self-proclaimed “world’s first sleep robot,” is designed to give you a more comfortable, energizing night’s rest.

The bean-shaped cushion is the perfect size and shape for cuddling as you drift to sleep. Beneath its soft exterior is hardware designed to get you to deep sleep faster. Somnox rises and falls to mimic the movements of human breathing. Lay with the pillow long enough and the designers claim your breath will naturally sync to its rhythm, thus prepping your body for sleep.

Somnox can also be set to play sounds and music. Some content, like guided mediation, lullabies, and gentle heart beats, come built-in, but you can also upload audio of your own. And you don’t need to worry about shutting it off: Once you've customized its breathing and audio behaviors through the app, the device does what it's programed to do and powers down automatically.

Having a robotic sleep aide will cost you: You need to pledge about $533 to the team’s Kickstarter to reserve one. Even with the steep price tag, the campaign surpassed its funding goal.
