Facebook CEO Mark Zuckerberg Posts Video of Jarvis Robot Assistant at Work

December 21, 2016

Dec 21: Mark Zuckerberg has a new housemate: Jarvis, an artificial intelligence assistant he created this year that can control appliances, play music, recognize faces and, perhaps most impressively, entertain his toddler.

The Facebook founder spent 100 hours putting together the virtual assistant - named after the artificial intelligence system in "Iron Man" - which understands spoken commands as well as text messages, he wrote in a 3,000-word Facebook post Monday.

Among Jarvis's skills: Adjusting the home thermostat, turning on lights and operating the toaster. The virtual assistant texts Zuckerberg images of visitors who stop by during the day, and opens the front door for those it recognizes. It can also tell when Zuckerberg's 1-year-old daughter, Max, wakes up "so it can start playing music or a Mandarin lesson," he wrote.

In a tongue-in-cheek video he posted on Facebook Tuesday, Zuckerberg offers an example of Jarvis at work: "Max woke up a few minutes ago. I'm entertaining her," the virtual assistant (voiced by Morgan Freeman) tells Zuckerberg, before turning his attention to the toddler. "Good morning Max, let's practice our Mandarin."

The year-long project was part of an effort to learn about the state of artificial intelligence, Zuckerberg wrote, and also an opportunity to experiment with cutting-edge technology at a time when voice-activated assistants like Amazon's Echo and Google Home are gaining widespread popularity.

"At this point, I mostly just ask Jarvis to "play me some music" and by looking at my past listening patterns, it mostly nails something I'd want to hear. If it gets the mood wrong, I can just tell it, for example, "that's not light, play something light", and it can both learn the classification for that song and adjust immediately. It also knows whether I'm talking to it or Priscilla is, so it can make recommendations based on what we each listen to. In general, I've found we use these more open-ended requests more frequently than more specific asks. No commercial products I know of do this today, and this seems like a big opportunity."

Building the robot was the easier - and less time-consuming - of his two goals for the year, he said. The other was to run 365 miles in 2016.

"Now I have a pretty good system that understands me and can do lots of things," Zuckerberg, adding that he's tried to give his robot a sense of humor. "I've taught it fun little games like Priscilla or I can ask it who we should tickle and it will randomly tell our family to all go tickle one of us, Max or Beast. I've also had fun adding classic lines like 'I'm sorry, Priscilla. I'm afraid I can't do that.'"

But there are also some kinks to work out, particularly around voice commands. When Zuckerberg demonstrated the technology for a Fast Company story, he had to ask the robot to turn off the lights four times before it complied. Shutting down the music took another two tries. ("Wow, that's like the most fails that it's ever had," the 32-year-old told the reporter, visibly embarrassed.)

Next up, Zuckerberg plans to create an Android app for the robot and connect it to more appliances around the house, such as his Big Green Egg grill. The ultimate challenge, he says, is "to build a system that could learn completely new skills on its own."

"In the longer term, I'd like to explore teaching Jarvis how to learn new skills itself rather than me having to teach it how to perform specific tasks," he wrote. "If I spent another year on this challenge, I'd focus more on learning how learning works."

After a year of coding, here's Jarvis.

In a first, the Supreme Court on Friday allowed the service of summons and notices, a necessity in almost all legal proceedings, through instant messenger like WhatsApp as well as by e-mail and fax.

A bench headed by Chief Justice SA Bobde observed that it has been brought to the notice of the court that it is not feasible to visit post offices for service of notices, summons, and pleadings. The bench also comprising Justices AS Bopanna and R Subhash Reddy observed that notice and summons should be sent through e-mail on the same day along with instant message through WhatsApp and other phone messenger services.

The bench clarified that all methods should be deployed for a valid service on the party. "Two blue ticks would convey that the receiver has seen the notice," noted the bench.

The bench declined the request of the Attorney General for specifically naming WhatsApp as a mode of effectuating service. The top court noted that it would not be practical to specify only WhatsApp. The apex court also permitted RBI to extend the validity of cheques in the backdrop of lockdown to contain the coronavirus outbreak.

Senior advocate V Giri representing RBI informed the bench that he had circulated the note regarding validity of a cheque as directions issued on the previous hearing.

The bench noted that it will be in discretion of the RBI to issue orders which are suitable to alter the validity of the period of a cheque.

During an earlier hearing on the matter on July 7, the Attorney General contended before the top court that the Centre had some reservations in connection with the utilization of mobile applications like WhatsApp and other apps for service of summons. The Centre's top law officer informed the apex court that these apps claimed to be encrypted, and they were not trustworthy.

The RBI counsel had contended before the top court that it was considering clarifying the validity of a cheque which has been reduced to 3 months from 6 months.

Leiden, Jul 2: Astronomers have discovered a luminous galaxy caught in the act of reionizing its surrounding gas only 800 million years after the Big Bang.

The research, led by Romain Meyer, PhD student at UCL in London, UK, has been presented at the virtual annual meeting of the European Astronomical Society (EAS).

Studying the first galaxies that formed 13 billion years ago is essential to understanding our cosmic origins. One of the current hot topics in extragalactic astronomy is 'cosmic reionization,' the process in which the intergalactic gas was ionized (atoms stripped of their electrons).

Cosmic reionization is similar to an unsolved murder: We have clear evidence for it, but who did it, how and when? We now have strong evidence that hydrogen reionization was completed about 13 billion years ago, in the first billion years of the universe, with bubbles of ionized gas slowly growing and overlapping.

The objects capable of creating such ionized hydrogen bubbles have however remained mysterious until now: the discovery of a luminous galaxy in which 60-100 percent of ionizing photons escape, is likely responsible for ionizing its local bubble. This suggests the case is closer to being solved.

The two main suspects for cosmic reionization are usually 1) a population of numerous faint galaxies leaking ~10 percent of their energetic photons, and 2) an 'oligarchy' of luminous galaxies with a much larger percentage (>50 percent) of photons escaping each galaxy.

In either case, these first galaxies were very different from those today: galaxies in the local universe are very inefficient leakers, with only <2-3 percent of ionizing photons escaping their host. To understand which galaxies governed cosmic reionization, astronomers must measure the so-called escape fractions of galaxies in the reionization era.

The detection of light from excited hydrogen atoms (the so-called Lyman-alpha line) can be used to infer the fraction of escaping photons. On the one hand, such detections are rare because reionization-era galaxies are surrounded by neutral gas which absorbs that signature hydrogen emission.

On the other hand, if this hydrogen signal is detected it represents a 'smoking gun' for a large ionized bubble, meaning we have caught a galaxy reionizing its surroundings. The size of the bubble and the galaxy's luminosity determines whether it is solely responsible for creating this ionized bubble or if unseen accomplices are necessary.

The discovery of a luminous galaxy 800 million years after the Big Bang supports the scenario where an 'oligarchy' of bright leakers emits most of the ionizing photons.

"It is the first time we can point to an object responsible for creating an ionized bubble, without the need for a contribution from unseen galaxies.

Additional observations with the upcoming James Webb Space Telescope will enable us to study further what is likely one of the best suspects for the unsolved case of cosmic reionization," said Meyer.

Washington D.C., Jan 20: An American bride asked for money from her invitees so that they can be on the 'exclusive guest list'.

Weddings can be surely expensive. But is it feasible for one to charge the guests to make up for the expenses?

According to Fox News, that is exactly what happened in a recent American wedding. A 19-year-old shared on Reddit that her cousin was getting married on Sunday and announced that she would charge 50 dollars to those who wanted to attend her wedding.

"She said that they can Venmo her money so there won't be no [sic] problems and everyone who paid will be added onto the 'exclusive guest list' which basically means you won't have to wait in line while other guests pay," wrote the user named DaintySheep.

While she refused to pay for entry into her cousin's wedding the bride-to-be contacted the elders in the family which ended up in an embarrassing situation.

"She wanted to get the money she spent on her special day back. I told her I wouldn't be able to come because this was outrageous and that I wish her well on her special day. She contacted my aunt and my aunt called me cheap and rude. My parents offered to pay for my entry, but I refused," continued the disheartened girl.

While in almost every nook and cranny of the world gifting the bride-groom with money is a tradition, asking for money from friends and family to replenish the money spent on a wedding is can be said to be a rare scenario.
