How technology for Drones can help cars too.

For drones to be safe, they need to be aware of other drones. To navigate, they anyway need GPS without line of sight operator control.

First, let us look at drones. Even operator controlled line of sight drones need to obey air traffic rules. If all drones are mandated to have internet connectivity at least when not flying above certain altitude, one could download the GPS co-ordinates and altitude limitations at a given GPS co-ordinates. In addition, enforcement authorities can have the ability to send real time GPS no-fly co-ordinates in peer to peer network to a flying drone. So, in case of a fire or an accident or the need to protect VIPs such as our President from drones, it can be done by the authorities.

What if the same technology is in cars? GPS in cars can help avoid congestion or accidents as cars communicate with each other in a mesh network even without internet. Under normal conditions, cars can be sent the speed limit signal to limit the speed automatically and give new meaning to dynamic or adaptive cruise control. That said, there is danger of hacking....

Who said technology is always great?

Home food for 4 yr old Female German Shepherd.

We came to know that a German Shepherd lived 19yrs on home food of raw meat, veggies. So, we dumped the factory processed dry food. Ziva weighs 73lb. Our target weight for her is 70 to 71lb.

Our Ziva's diet:

Morning: 7:30am

Half cup mix of cooked brown rice, frozen peas, beans, corn and some fresh carrots. about 8oz of raw boneless skinless Chicken thighs bought at Costco, 1 boiled egg, 3 squirts of Fish oil, 2 tablets of Glucosamine Chondroitin for Dogs, 1 capsule of Vit E.

Evening: 7:30pm

Half cup mix of cooked brown rice, frozen peas, beans, corn and some fresh carrots. about 8oz of raw boneless skinless Chicken thighs, 3 squirts of Fish oil.

Afternoon: 3pm

A dozen peanuts roasted in the shell or a piece of Chicken jerkey.

Exercise:

Equivalent of 4 miles, elevation gain 500ft at least 4 times a week and walk on surface streets for about 10 miles a week.

She loves to run after a squeaky ball about 25 times a day or more.

If she gets less exercise, we cut out the egg and afternoon snack.

Her coat is lot more shiny. She is not scratching as much as before. Very athletic when she jumps on all fours to catch a ball in the air.

Phone getting hot and draining battery? May be you should try disabling GPS when not in use.

I wrote a review on Android My Tracks App:

This is for Samsung Galaxy Note 3 SM-N900T T Mobile current version
experiencing "waiting for gps"
Andriod 5.0
Google Play Services 7.5.74
My Tracks 2.0.10
Kernel version 3.4.0-4086253

See https://code.google.com/p/mytracks/issues/detail?id=1579

Based on suggestions by others, I did the following before opening My Tracks.
1. Close all Apps which use GPS.
2. Open App GPS Status.
3. Background Behavior is set to Use GPS when screen is off.
4. Leave GPS Staus App running after ensuring that all satellites are green and error is lowest.
5. Open My Tracks.
6. Touch he GPS button and wait till it is blue.
7. Touch the Record button..

Open Maps tab and ensure that there is no message "waiting for GPS"
The App should work as you expect. Problem is that by itself My Tracks App is not enabling GPS but looking for GPS signal. It is ridiculous that Google cannot fix its own App. It used to work fine in Android 4.3, started acting up in Android 4.4 and needs this work around to work in Android 5.0.
There is one other thing I found. The battery was draining faster without this because My Tracks was looking for signal constantly. I disabled GPS after I no longer needed it. After using GPS for 1hr15min and using the phone as usual battery life is now 59%. Projected battery life is 13hrs. Phone is not getting hot now.
