Two hikers missing for five days on California’s Mount Baldy have been found alive after rescuers tracked their footprints to their camp, according to authorities.

Eric Desplinter and Gabrielle Wallace had gone hiking in the San Gabriel Mountains in San Bernardino County, California, on Saturday, April 6th and were expected to return that night. But when the two hadn't returned by 8 p.m., friends reported the two missing.

The San Bernardino County Sheriff said late Wednesday the two had been rescued after days of desperate searching over a 30 square mile area.

Authorities said rescuers found two sets of footprints in Cucamonga Canyon Wednesday at which point they alerted a search-and-rescue helicopter to fly over the area. The rescue team spotted Desplinter, 33, and Wallace, 31, at a campfire and lifted them to safety late Wednesday.

The pair lost the trail and when they tried to descend through a valley, it "was more treacherous than we thought," Desplinter said.

Desplinter was an experienced hiker, but authorities previously said the two had limited supplies of food and water.

The campers rationed what little food they had and drank water through a LifeStraw. This technology can filter dirty water. The ability to stay hydrated was one of the mitigating factors rescuers said helped to make the recovery a success.

LifeStraw products use a hollow fiber membrane. These membranes have microscopic pores that trap contaminants. Bacteria and parasites are bigger than the pores in the filter. Water can pass through, but contaminants larger than 0.2 microns remain trapped. Some LifeStraw products use a two-stage filtration process. In addition to the hollow fiber membrane, a carbon capsule absorbs chemicals like chlorine, pesticides, and even heavy metals like lead.

"Eric and Gabrielle will be flown to the Mt. Baldy Fire Station where they will be reunited with their families and loved ones," the sheriff's office said in a statement.

Volvo announced that it would use cameras installed inside its vehicles to monitor driver behavior and intervene if the driver appears to be drunk or distracted. It’s a risky move by an automaker, even one with a reputation for safety like Volvo, which could raise concerns among privacy advocates. 

Volvo’s in-car cameras will monitor eye movements to gauge driver distraction or intoxication. If a driver looks away for some time, such as at a smartphone, or fails to keep their hands on the steering wheel, a representative from Volvo’s on-call assistance centers will call them to check in. Drivers who aren’t watching the road, or even have their eyes closed, will be warned as well. If they don’t respond, the car will slow and also stop. The system will roll-out to all Volvo cars by early 2020. 

This follows Volvo’s recent announcement that it will be limiting the top speed on all of its vehicles to 180 km/h (112 mph) in a bid to reduce traffic fatalities. Volvo is framing these new policies as crucial components in its Vision 2020goal, in which no one is killed or seriously injured in a Volvo vehicle by 2020. Over the years, the company built its reputation on safety and quirky designs, and today’s announcement is meant to underline that.

“When it comes to safety, our aim is to avoid accidents altogether rather than limit the impact when an accident is imminent and unavoidable,” Henrik Green, senior vice president for research and development at Volvo Car Group, said in a statement. “In this case, cameras will monitor for behavior that may lead to serious injury or death.”

The use of in-car cameras to monitor drivers is not entirely unprecedented. Cadillac uses infrared cameras facing the driver to power its advanced driver assist system, Super Cruise. The camera tracks the driver’s eye movements, allowing for a “hands-free” driving experience. If the driver’s attention wanders, Super Cruise uses an escalating series of audible and vibrating alerts to ensure the driver keeps their eyes on the road.

As camera use increases in the name of safety, there’s a real chance they can be misused to invade privacy. At an event in Sweden, the company preemptively dismissed this criticism by likening it to early objection to seatbelt laws. 

A spokesperson for Volvo did not immediately respond to questions about the storage of video footage or whether law enforcement could have access to it. Automakers are already collecting lots of information from your car today, but mostly for vehicle analytics. 
​
GM has said that the camera in its Cadillac cars isn’t recording anything; it’s just a buffered video feed to make sure Super Cruise works as it should.

Drivers will soon have an extra set of eyes on the road, courtesy of Google.

Google’s navigation app, Google Maps, is starting to roll out speed limit and speed trap features. 

With the speed limit feature, drivers using Google Maps will be shown the posted speed limit of the road they’re driving on in the lower left side of the app. Speed traps are designated with a small camera icon and shown on the visible area of the map. The Maps app provides an audio warning for drivers when they are approaching a speed trap.

Users have had the ability to report speed traps in Google Maps since late last year. However, until now, the app wasn’t yet making the reported speed traps visible for users in maps. 

Google Maps users have long wondered when such features were going to make their debut on the service. Crowdsource-powered navigation app, Waze, grew in popularity for providing this sort of detailed information on the road. Google acquired Waze back in 2013 for around $1 billion. 

Now, nearly five and a half years later, some of the Waze features are finally making their way to Google Maps.

A lot of people have become bored with SMS messaging, and the tech industry is very aware of it. While services such as Apple’s iMessage, Facebook Messenger, and the WhatsApp app allow you to add photos, GIFs and videos to your messages, they are not universal solutions – for example, you can’t send a WhatsApp message if your correspondent uses Facebook Messenger. The answer – or so Google and other companies are hoping – is Rich Communications Services or RCS.

What is it? RCS is a new online protocol that was chosen for adoption by the GSM Association(CSMA) in 2008 and is meant to replace the current texting standard SMS (Short Message Service), which has been around since the 1990s. The GMSA represents a wide variety of organizations in the mobile industry, including device, software, and Internet companies. Naturally, given all those players, it took a while to come to an agreement, and so it wasn’t until 2016 that the GSMA was able to come up with something resembling a standard.

How is RCS better than SMS? RCS will add a lot more multimedia capabilities to your messaging. Besides the usual texts (plain and fancy), it will make it simple to send GIFs, high-resolution still photos, and videos. It will let you know if the person you’re texting is available and can send you a receipt to prove they received your message. It will allow you to create longer messages and attach larger files. It also enables much better group messaging than SMS can handle. In other words, it can make standard text messaging look and work a lot like iMessage.

As of this writing, support for RCS has been promised by 55 carriers including AT&T, Verizon, T-Mobile, and a slew of secondary companies; 11 hardware manufacturers such as Samsung, Lenovo, and LG (but not Apple), and both Microsoft and Google.

Is anyone using RCS yet? Google has been a significant backer of RCS and even offers back-end services to carriers to help them quickly spin up support for it. But at the end of the day, it’s the carriers that are responsible for launching and supporting it. The big recent news is that Verizon is beginning its rollout of the service, but only in a minimal way to start. Currently, Verizon only offers it on Pixel 3 and Pixel 3 XL phones – and even then, it hasn’t hit all those customers yet. But because Verizon is supporting the standard, it will work with any other phone that supports it.

Why are people saying it’s not secure? One issue that a lot of security specialists are pointing out is that RCS – and, therefore, apps such as Chat – lack the end-to-end encryption available in some current messaging tools such as WhatsApp. End-to-end encryption means that the message is impenetrable to everyone – including the app vendor and the network provider – except the message sender and receiver. If you want to text someone with no chance that the authorities will ever see it, Chat / RCS is not the way. 
On the other hand, RCS does have all the standard security protocols, including Transport Layer Security (the underlying tech behind HTTPS), and IPsec (Internet Protocol Security), which is used in VPNs. So, for the most part, it’s pretty secure. Whether you’re comfortable using Chat / RCS depends on your security needs.

What’s next? Right now, support for RCS is limited to only a few carriers and even fewer devices, which means that most people can’t yet take advantage of it. Stay tuned to see what – and who – follows.

Honda Research Institute has announced a breakthrough battery chemistry developed in collaboration with Caltech and NASA JPL researchers. The technology, which was detailed in a newly published study, has a better eco-footprint while enabling the use of higher energy density materials in comparison to existing battery tech.

Honda says the new technology sidesteps fluoride-based battery technology temperature limitations. The team successfully demonstrated the operation of fluoride-ion based energy cells at room temperature, opening the door for high energy-density batteries that better meet the high capacity needs of modern technology.

Even better, the researchers say that unlike popular lithium-ion batteries, which are known to be volatile, fluoride-ion batteries are safer without the risk of overheating. As well, this battery technology is better for the environment due to the lower environmental impact of its source materials.
​
Batteries created with this new chemistry may have up to 10 times the high energy density of lithium-ion batteries, according to the study. Despite the upsides, this type of battery hasn’t replaced lithium-ion due to its temperature limitations – until now, it has required temperatures above 302º F degrees to work correctly.
Researchers with Honda, NASA, and Caltech, overcame this limitation and developed a fluoride-ion cell that can operate at room temperature. The team achieved this using a fluoride-conducting liquid electrolyte that has high ionic conductivity, as well as a wide operating voltage. Such technology may one day be behind batteries that power everything from consumer gadgets to electric vehicles.

Sirius XM’s recent all-stock $3.5-billion purchase of the music-streaming service Pandoraraised a lot of eyebrows. A big question was why Sirius paid so much. Is Pandora’s music library and customer base worth that amount? The answer is that this was a strategic move by Sirius in a battle that is far bigger than radio. The real fight, which will become much more visible in the coming years, is over the driving experience.

People spend a lot of time commuting in their cars. That time is fixed and won’t likely change. However, what is changing is the way we drive. We’re already seeing many new vehicles with driver-assist features, and automakers (and tech companies) are working hard to bring fully autonomous cars to the market as quickly as possible. New vehicles today already contain an average of 100 million lines of code that can be updated to increase driver-assist options, and some automakers like Tesla already offer an “autonomous” mode on highways.

Even conservative estimates predict that we are likely to see significant changes in autonomous driving in the next ten years.

These changes will impact the driving experience. As cars become more autonomous, we can do more than just listen to music or podcasts. We may be able to watch videos, surf the web and more. The value of car real estate is already valuable, but it’s going to skyrocket as we change the way people consume media while driving. 

The Pandora acquisition was a strategic move by Sirius to gain the necessary assets so that it won’t fall behind in this space – and to get into the fast-growing music-streaming business, where users consume music at home, work and play. While Pandora’s music library is arguably second-tier, it’s also good enough that it can provide pretty much every artist most people want. This is often how high-priced mergers happen – one party is concerned about falling behind and pays a premium to purchase the other company’s assets. It’s also a bet by Sirius about the driving experience of the future.

For now, Sirius probably doesn’t need to worry about competition from startups. They won’t be able to grow big enough, fast enough to get a sizable share of the market. A more likely scenario is that startups will work on software that offers unique functionality, making it an attractive acquisition target by a larger company.
​
This is going to be an interesting battle to watch in the coming years, as cars essentially become software with four wheels attached. Companies like Sirius know this is a valuable space and that the battle over the driving experience will be won in software. The acquisition of Pandora is only the beginning.

Google frequently touts that the “next billion users” will come from developing nations with different focuses and needs. To that end, the company has developed several optimized services, with one being a consistent and straightforward addressing system that works globally.

Google created “Plus Codes”for addresses that are not easily located through conventional descriptors. First introduced in February 2018, Plus Codes allow users to locate almost any spot on the planet. What many people in traditional civilizations fail to realize is that, according to a World Bank estimate, half of the world’s urban population lives on unnamed streets.

Notably, this open source solution composed of 10 characters works globally and can be incorporated by other products and platforms for free, with a developer page available here.

It works offline and in print when overlaid as a grid on existing maps. Places that are close together share similar plus codes, while the system is identifiable by the “+” symbol in every address.

This system is based on dividing the geographical surface of the Earth into tiny ‘tiled areas,’ attributing a unique code to each of them. This code comprises a ‘6-character + City’ format that can be generated, shared and searched by anyone – all that’s needed is Google Maps on a smartphone.

                   •   The first four characters are the area code, describing a region
                        of about 100 x 100 kilometers.

                   •  The last six characters are the local code, describing the neighborhood
                       and the building, an area of approximately 14 x 14 meters – about the
                       size of one half of a basketball court.

The area code is not needed when navigating within a town, while another optional character can be appended to provide additional accuracy down to a 3 x 3-meter region. Plus codes for any location can be found with this tool.

Thirty years ago, it was a big deal when schools got their first computers. Today, it's a big deal when students get their own laptops.

According to Thomas Frey, the senior futurist at the DaVinci Institute think tank, “In 14 years it'll be a big deal when students learn from robot teachers over the Internet.”

It's not just because the technology will be that sophisticated, Frey says, but because the company responsible for it will be the largest of its kind.

"I've been predicting that by 2030 the largest company on the Internet is going to be an education-based company that we haven't heard of yet," Frey said.

Frey's prediction comes amid a boom in artificial intelligence research. Google is developing DeepMind; a complex piece of machine-learning software and IBM is developing Watson-powered robots.

"Nobody has quite cracked the code for the future of education," Frey contends.

His vision for 2030 includes a massively enhanced version of today's open online courses – the kind of instruction you may find with Khan Academy, Coursera, or MIT OpenCourseWare. Only, the instructors won't be humans beamed through videos. They'll be bots, and they'll be smart enough to personalize each lesson plan to the student sitting in front of the screen.

Frey suspects that a new kind of efficiency will allow students to learn at much faster rates than if they had to compete with 19 other students for the teacher's attention. Students will breeze through their material at four or 10 times the speed, completing an undergraduate education in less than half a year.

"It learns what your proclivities are, it learns what your idiosyncrasies are," Frey explains. "It learns what your interests are, your reference points. And it figures out how to teach you in a faster way over time."

He uses the example of Google's DeepMindlearning to play the Atari video game "Breakout." Not only did it quickly pick up on the rules, but within a half hour it figured out a way to achieve incredibly high scores – all with little human input.

Machine learning will accelerate similarly in the education space, Frey says. Online bots will pick up on a student's strengths and weaknesses and use a series of algorithms to tailor the lessons accordingly. Research suggeststhis personalized method is among the most effective at raising kids' overall achievement.
Frey doesn't go so far as to argue education bots will replace traditional schooling outright. He sees them more as a supplement or a kind of tutor. If a child struggles with algebra, a bot may be able to offer some help during homework time or over the weekend.

It's up for debate whether AI can master the subtleties of language, thought, and reason all within the next 14 years. One of the most significant hurdles for machine learning is grasping social interactions. Many AI systems today are still less capable cognitively than a 6-year-old.

Frey trusts 14 years isn't too generous a timeline for the technology to ramp up, given how quickly technology innovation builds on itself. The Internet was beginning to enter a lot of people's homes 14 years ago. But by 2007 people were already surfing the Web on their iPhones, and today the Internet is almost omnipresent in daily life.
​
Frey predicts that artificial intelligence will have the same trajectory in the education space. By 2030, DeepMind's ability to master "Breakout" could seem as quaint as dial-up modems do today, and what seemed like a massive library of online content in 2016 could look to future students like a skimpy collection that hardly does anything.

Last Monday was the first day that French schoolchildren under 15 could not use their cellphones at any point during the school day, thanks to a new nationwide law.

The ban, passed in July following a campaign pledge made by French President Emmanuel Macron, will affect elementary and junior high schools across the country as they return from the summer break.

The new law, which went into effect on August 5, bans all types of cellphones, as well as tablets and smartwatches.

While a ban on cellphones during class hours was already in place since 2010, the new law extends to breaks and mealtimes.

Schools are free to choose themselves if they implement the ban for students over 15. There are also some exceptions to the prohibition, such as for students with disabilities.

Under the new law, students have to turn their phones off during the day or put them in lockers. Schools will independently deal with the logistics of how students will be kept away from their phones.

The law was introduced amid fears that students were becoming too dependent on and distracted by their smartphones.
​
Education Minister Jean-Michel Blanquer in June hailed the legislation as "a law for the 21st century," and said it would improve discipline among France's 12 million schoolchildren.
