My experiment on wifi and sleep indicates that wifi damages to sleep if you are in the same building.
If wifi is in the neighborhood it does not seem to matter.
Intensity declines proportionally to the square of distance from wifi source.
So neighborhood wifi cannot penetrate multiple walls and distance very well.
Caffeine is a bigger problem that wifi.
And carbohydrates and blood sugar.
Eat carbos late and sugar will crash while you sleep and you will wake up anxious.
Eat a light fatty early dinner so you will be in ketogenic state all night and sleep better.
Wake up hungry
No wifi on the phone
Use a separate device for free wifi.
Use a VPN with wifi.
I am using free wifi now on my Apple ipod that is for nonimportant stuff.
Apple is good on music and photos.
Important stuff on my android phone that is turned off almost always.
I may go back to dumb phone Tmobile Nokia for phone and text.
Save android for checking email and banking and shopping.
And tethering to a bigger computer for much interaction.
I will probably get a Chromebook this week.
Trying to decide which one.
May be my main computer.
I hate typing on smart phone screens.
My LG has a bug that ruins the keyboard typing.
My Moto Sprint works better. But not as good as a real keyboard
It is nearly not worth the effort to buy and learn any electronics except a dumb phone.
Computers, TV, radio, gone downhill since mass market to sheeple.
Have been a tool for mind control and tracking
so elites can better control the sheeple.
Badmouth anybody who wants to fix the political and economic system.

Go to Las Vegas.
Rooftop solar could be exploited by hackers, some cybersecurity workers are warning.

We know emails can get hacked. But what about solar panels?
The computer security industry’s annual pilgrimage to Las Vegas this week for a trio of conferences will hash out the myriad, creepy ways criminals can breach our increasingly connected world.
Among this year’s talks: the possibility drones perched high up on buildings could link into unsecured networks, the ease even a bored teen-ager could take over an Airbnb rental’s Wi-Fi, ransomware used to hijack connected cars, and how a hacked roof-top solar array could destabilize an entire power grid.
A drone avoids a perimeter fence at a water treatment plant in Georgia.
Black Hat is the largest of the three gatherings, counting over 11,000 in attendance last year, and the most prestigious. Of the two others, DefCon is more for hackers while BSides is more technical.
“The bad guys communicate really, really well. They have an entire ecosystem for sharing and monetizing techniques. Our corporate security community doesn’t have those tools, but we have Black Hat and DefCon and BSides,” said Gunter Ollmann, chief security officer at Vectra Networks, a security firm based in San Jose.
These are the hacking scenarios that have got the cybersleuths talking:
Wi-Fi dangers at vacation rentals
In the “so easy, and yet so dangerous” category comes a talk Thursday by security intelligence researcher Jeremy Galloway ofcloud software company Atlassian in Austin, Texas.
When on a snowboarding trip in Colorado with some friends recently, he realized their Airbnb rental came equipped with Wi-Fi — and that the Wi-Fi router was sitting in plain sight.
All he had to do to get into the server was pick up the router, unbend a paperclip and use it to reset the router. At that point he could have put a snooping program in place that could watch the Wi-Fi network long after he had checked out, sending updates that could include other guests’ login credentials and passwords to multiple networks.
The danger is not simply to Airbnb rentals but any home-based rental where the hosts are not tech or security savvy. He recommends home property owners who have Wi-Fi in their rental space physically lock up the device, either in a closet or another secure area.
With connected cars coming up fast in the rear-view mirror, researchers at ESET, a security company, see ransomware aimed at cars as a likely future exploit.
The nightmarish scenario is that you get into your self-driving car, the doors lock and a message pops up on the screen saying, “Pay us ransom or we won’t let you out.” Or perhaps even threatens to take you somewhere you don’t want to go.
“Everything I see points to jackware as a logical development. It’s not inevitable, but it’s up to the people who make cars to prevent it from becoming a reality,” said Stephen Cobb, a senior researcher for the firm based in San Diego.
Installing solar panels can open homeowners up to hackers, according to a presentation scheduled for Friday by security researcher Frederic Bret-Mounet.
After installing solar panels on his home near San Francisco, he noted the array was connected to the cloud. It took him a single weekend to hack into his own system.
Once there, he realized that had he been malicious, he could have overridden the safety limits on the system, causing it to overheat and then be knocked offline. He could also have remotely set off the solar array’s emergency shutdown protocol.
He also realized he could have potentially compromised devices in thousands of homes. Not only that, but “I could have installed spying software that would have had visibility into their home networks, seeing their emails and everything they did online,” he said.
While having one or two solar power systems in a neighborhood go out might inconvenience a few people right now, California has set a goal of 50% of the state’s power coming from renewable sources by 2030.
Tomorrow, when solar arrays are ubiquitous, ”these lightly-protected systems could then be all too easily infiltrated, possibly with catastrophic effects on the state’s power grid”, he said.

A drone perched near an industrial site.
To Jeff Melrose, a strategist for cybersecurity at engineering services supplier Yokogawa US, drones are a terrifying threat to industrial installations, from power and chemical plants to factories.
“In the old days, a fence kept people out of your plant. Now a drone can just fly right over it,” he said.
A drone can almost silently creep in, perch and watch for days. It can also find its way to a hidden corner of a building and then serve as a connection to any open Bluetooth or Wi-Fi networks or even a wireless mouse or keyboard.
Drones are also close to risk-free to the attacker. “You can put up an untraceable drone and if it gets caught, it gets caught. It’s basically risk free,” said David Latimer, a security analyst at Bishop Fox, a security consulting firm in Tempe, Ariz.
