Comment Re:Signal triangulation = GPS (Score 2) 173

Some weapons are GPS-guided, such as JDAM-assisted bombs.

The world is gearing up for a heated conflict. Wether it occurs or not is a different story. But last month's US chief of armies gave a chilling speech where they expect mass casualties within 10 years, to the likes of WWII.

The nations are placing their pieces on the map and gearing up for defence. GPS denial devices is an obvious counter-measure, assuming it actually deter military -grade GPS systems (which are far more precise than civilian ones).

It's catchy to slide in Tesla in unrelated articles but just because it uses batteries doesn't mean they are prone to fires.

The one that famously caught fire and torched a supercharger in Europe was caused by a genuine one-off assembly line defect.
The one that caught fire in France during a test drive was found to have a a faulty electrical connection.
The one that crashed on autopilot and "battery caught fire" actually didn't burned down: it smashed into a tree separating the front of the vehicle from the cabine, tearing the battery apart where a small number of cells separated from the rest and autopilot tesla crash fire caught fire, away from the vehicle and the rest of the battery pack. Driver dies of impact.
Another one caught fire due to hitting debris where car alerted driver to pull aside.

Complete list of EV fires exonerate batteries for the most part, as most EVs (Tesla and Chevy Volt) have liquid-cooled battery packs, unlike consumer electronics (esp. handheld devices).

Dont want to sound like a fanboi but, lots of hate & vendor lock-in comments in regard to Apple truly isn't warranted.

The iPhone 4s (ancient by any smart phone measure) is capable of running iOS 9 while base line for iOS 10 is the iPhone 5.

Adoption of iOS 10 is now > 50% on all compatible devices.

So, while Linux and Android fans hate on, Apple supports and updates it's users.

In Obj-C, Code Blocks are an awesome way to un-spaghetti-fy source code by doing away with protocols.

Translate that to Java:

In Java, Lambdas are an awesome way to un-spaghetti-fy source code by doing away with interfaces.

In Obj-C, we've been able to clean up and streamline our code a lot using completion blocks. But as with any technique, you can be an idiot using it. It's all about proper usage. Knowing when to eat your spag and when to eat the meat balls.

118,000 EV miles. 53 miles per charge. That's 2,226 full charge cycles. Sparkie travels an average of 66,000 miles per year (long commute) since 2011 (2012 model... 2011... 5 years).

That's more distance than most will do with their dino cars.

Proper thermal management is done on these batteries because GM did their work: they have the largest battery lab.

The Volt's Gen2 battery is 18.5kw but only about 14.5 is available for driving. The remainder is used for thermal management and avoiding deep charge cycles, which is really what destroyes life expectancy of Li-Ion batteries. And that's why they last long.

Gen 1 used different battery capacities but still had that ~20% thermal overhead. Also, unlike laptop and phones, these batteries are liquid-cooled with their own glycol, 5-channel cooling system (Tesla only has a single-chanel system).

Disclaimer: I both a Gen2 Volt and a CSRT4.

My Volt will rot to the ground before I have to worry about the battery.

You wont have to replace your hybrid battery. That's myth brought on by cheap laptop & cell phones horrible power managements. Further propagated by the Cock Brothers (typo intended).

Sparkie raked up more than 118,000 EV miles, on a car with more than 330,000 miles with no loss of charge on his 2012 Chevy Volt.

Chevy has recently mentioned is has replaced exactly NONE of it's > 100,000 Volt batteries out there du to degradation.

Planes do detect other planes in proximity with the aptly-named proximity warning. Miles in advance. With beeps buzzes and autopilot disengagement. They are called ACAS. There are various levels of support depending on version being used by an aircraft.

If the pilot fails to respond, there's a loud bang and a cut on his paycheck.

I dont think this car economy model constructors are aiming for will ever work.

They want to help you subsidize your own car payments by allowing you to "rent" your car through auto-driving capabilities.

But looking at how people disrespect other people propriety, there's no way in hell any sane person would allow total strangers to use their cars, unsupervised.

You'' go back to your car with mud on the seats, semen on the carpet, trash and dead hookers in the trunk.

My car is not your public transport. Dont try to find reasons and means to rise car prices under the pretence that it pays for itself.
