Well rolled: the AI ​​manages it in record time (photo:

Developers have trained an AI on solving Rubik’s Cube. For some time, robots and machines have been able to turn the colorful magic cubes in less than a second. The project DeepCubeA surprises the world of technology according to a report by Nature but with a completely new approach:

This time, AI is used to solve the puzzles. With 1.2 seconds, this still takes a comparatively long time for the solution. It takes an average of 28 steps to properly spin a cube.

To achieve this, more than 10 billion puzzles were submitted to the AI. In more than 60 percent of cases, the AI ​​finds the shortest route to the destination.

By voice command can be deleted for the first time all records of Alexa

Pssssst! Amazon’s language assistant Alexa has learned the whisper (Photo:

Already earlier in the year it had promised Amazon, now the plan was implemented. With the voice commands “Alexa, delete everything I said today” or “Alexa, delete everything I’ve just said”, you can play it safe with the smart language assistant and Amazon removes all the sayings of the day from the servers.

Whether the promise is actually put into action, of course, can not be checked. But hope dies last.

Important: Who wants to use the delete function, must in the Alexa app under “Settings” -> “Alexa Privacy” checkmark in “voice record history” set. Only then the deletion by voice command is possible. Exactly at this point in the settings, the history of all voice recordings can also be deleted manually.

The US start-up Connected Wise is working on developing the traffic solutions of tomorrow with artificial intelligence. Motto: “We help the world’s tanzportation become smarter and safer”.

With its new project, the company is now receiving a lot of attention. The company claims to have developed a solution for traffic signs for self-driving cars.

Normal traffic signs are designed for human drivers. Computers can not recognize them very efficiently. As an alternative, radio signals come into question, but to install and operate them is relatively expensive.

The solution: films that reflect UV light. For humans, they are transparent and therefore not visible. However, computer cameras can detect the printed information, reports Heise, These slides then show combinations of colors and shapes for cars.

They are relatively easy and reliable to assign a road sign. The UV films will simply stick to existing traffic signs.

Wonderfully nostalgic: All macOS-X intros in a YouTube video

Long-time Mac users will have tears of joy in their eyes when they remember it: Mac OS X greeted its users for a long time with a short video as a welcome. This was established with OS X 10.0 Cheetah: the first time the system was launched, an intro video was shown up to OS X 10.2: a water animation with effects and the word “welcome” in various languages.

All clips of a past macOS era are now available in a new YouTube clip, of course with sound. To the handkerchief grab for the memory tears – and film:

Not at all: TV makes friends (Photo:

A recent British study titled “Visually attending a video together with great ape social closeness” shows, according to a report by Slashgearthat chimpanzees and bonobos can share their experiences with each other. When two of the animals do something together, they get closer – as do humans.

To demonstrate this, two monkeys were given a TV and they could watch TV together. After the date in front of the TV set, the monkey couples spent more time together. Even if no television has been shown. This also worked for a mixed group of humans and monkeys.

The study of Royal Society has so far only dealt with the short-term effects of the experiment. How the effects are to be considered in the long term, the authors Wouter Wolf and Michael Tomasello still have to evaluate in the future.

The end of the LEAD: Mondays for future

Futureme can be used for free. Optionally, you can also purchase the pro version for up to 100 users for $ 49 a year. This allows more customization options for emails, better message management and more. Please, Mister Postman: So let’s hope that Futureme still exists in 50 years.

I wish you a lively Monday. See you tomorrow at TechTäglich!

By the way: TechDaily is also available as a newsletter and as a skill (“Alexa, open LEAD digital Tech”).
