How to Fix Coffee-Shop Wi-Fi

4/28/2019

When you’re on the road, Starbuck’s ‘third space’ idea can become compelling. You might want to get out of your hotel room for a change of atmosphere, or you might need a better cup of coffee. And you probably still need to get online with something other than your phone, and coffee shops mean Wi-Fi as much as caffeine.

If you pick the big chains, the Wi-Fi is pretty reliable. If you choose a smaller shop, the coffee is often far tastier, but the wireless can be hit and miss. A journalist writing about this problem, went into a little coffee place in Seattle to get out of the rain and catch up on some work over a weekend, his phone warned him that it could connect to the Wi-Fi but not to the internet.

He had the same problem when he connected his laptop to the coffee shop Wi-Fi. It’s not always possible to diagnose what’s wrong with a Wi-Fi connection; often the bandwidth is overloaded by the number of people connected to free Wi-Fi, or the router isn’t correctly configured to hand out IP addresses to devices. That means waiting for a few people to leave or asking the staff to restart the router.

But frequently, the problem with networks is DNS; the wi-fi router is probably using the DNS server of the ISP to which it’s connected. Switch to a public DNS service like Cloudflare’s 1.1.1.1, and you should get connected – and probably find websites a bit more responsive, too.

In Windows 10, click the network indicator in the taskbar to open the network menu and choose Change adapter options to open the Network Connections control panel with the list of network hardware you can use. Right-click on the wi-fi connection and select Properties. Click on Internet Protocol Version 4 (TCP/IPv4) and choose Properties again, then click to fill in your DNS details. Fill in 1.1.1.1 to use the Cloudflare service; you can use 1.1.1.0 for the alternative DNS server if you want Cloudflare as the fallback, or 8.8.8.8 to use Google’s DNS service.

You can do the same thing on a Mac. Choose System Preferences / Network and select your wi-fi connection, then click Advanced and choose the DNS tab. Again, fill in 1.1.1.1 to use the Cloudflare service; you can use 1.1.1.0 for the alternative DNS server if you want Cloudflare as the fallback, or 8.8.8.8 to use Google’s DNS service. 
​
On an iPad, look under Settings / Wi-Fi and tap next to the Wi-Fi network name. Scroll down and select the Configure DNS option, then tap Manual and fill in the addresses. Then you can get back to your coffee and  on with some work.

Amazon’s Plan for 3,236 Satellites to Beam Faster, Cheaper Web to Millions

Amazon has plans to establish a constellation of 3,236 satellites in low Earth orbit to patch up areas with poor or no internet connectivity.

Amazon's planned push into satellite-delivered broadband is taking shape under Project Kuiper, details of which appear in three documents filed with the International Telecommunication Union (ITU) last month. Kuiper Systems LLC filed the reports.  

The documents reveal Amazon plans to put 3,236 satellites at three different altitudes. There would be 784 satellites orbiting at an altitude of 367 miles; 1,296 satellites at 379 miles; and 1,156 satellites at 391miles.  
An Amazon spokesperson confirmed the existence of Amazon's satellite broadband ambitions, noting that it was a "long-term project that envisions serving tens of millions of people who lack basic access to broadband internet.”

The company is also planning to partner with other companies to bring the project to reality.  

That could make companies in the space-broadband race, like SpaceX and OneWeb, potential rivals or partners. The FCC in November authorized SpaceX to deploy and operate 7,000 satellites in very low Earth orbit to deliver broadband. 

OneWeb, which has $2 billion in backing from the likes of Airbus, Coca Cola, Softbank, and Virgin, in February, launched six satellites with the same ambition. Amazon CEO Jeff Bezos' Blue Origin space venture already has a contract to launch satellites for OneWeb and TeleSat. 

Meanwhile, Facebook, Boeing, and LeoSat have revealed plans to beam the internet from space. Alongside SpaceX's FCC authorization, the regulator also authorized spectrum in the US for both TeleSat's and LeoSat's space broadband systems.   

Should Amazon's plans come to fruition, its satellites would provide about 95% of the world's population with coverage between latitudes 56ºN to 56ºS. The two parallels circle the Earth at about the latitude of Sweden and below Australia.  

Amazon will still need to get approval from the FCC and other regulators around the world to move forward with Project Kuiper. 

Satellite internet today is typically costly. However, there is hope that satellites in low Earth orbit will be cheaper and offer lower latency.
​
Amazon said it would "of course look at all options" when asked whether Bezos' Blue Origin would have the edge over others for launching the Kuiper constellation.

Technology Helped Hikers SurviveNearly Five Days in California Mountains

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 Introduces in-Car Cameras to Combat Drunk and Distracted Driving

4/7/2019

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.
