"Subject of the week | What are your favorite smartphone apps?"
Having recently switched from a Blackberry to an Android phone, I am discovering a whole new world of apps. However the main apps I have used so far other than social media are Gasbuddy for finding the best fuel prices, and Fuelly for tracking my fuel consumption.
I have also been looking into an application called Torque for live tracking of vehicle performance data, but have recently changed cars and want to see if it will still do what I want. In fact may even write an an article about that once I get it set up properly.

I am learning about a new interesting app every time someone is posting.  For sure I will try some of them.  I also remember when I moved to Sao Paulo (population 12 million) / Brasil I had to buy a huge, heavy book with the city directory, with the street maps. Sometimes to find a place it was a complete nightmare.  Nowadays, with google maps, it would be a dream.

I was trying to figure out why my 1986 F150 wasn't holding charge and found out it was the battery. I had pulled the alternator and battery off to have them tested. While reinstalling the alternator I touched a hot wire to the frame and now it won't crank. When I turn the key I no longer hear the file pump or anything under the hood turn on. It will turn over but not fire. Any help would be appreciated.

I bought this vehicle a month ago. Before that I have 2015 RAM 1500 Pickup truck and this truck gave me a very good average miles on highway. The new GMC burn gas like a hell I feel that it might given me under 10 miles a gallon. Do I need to take it back to the dealer?

I'm programming Infineon TC29x Aurix Tricore Microcontroller based embedded system in 'C' language.
 
Consider stack starting at address 0x5000 0000.  The stack size is 0x1000.  

If I add 0x1000 to current stack pointer(Register A10) and store result in A10, then I should get underflow error.

What might be the code in assembly to change stack pointer?  something like following:

stw a10, 0x1000(a10)   # I'm not sure if stw is correct opcode ?

what are other options to create stack undeflow exception?

Btw petrol = gasoline (UK / US terms).

Occasionally I drive past petrol kiosks (that have offer) for
Octane 100 & I thought of topping them to the max (as my
wife doesn't want me to keep petrol at home & there's a
legal requirement to register for using container to buy
them as petrol could be used for malicious purpose).

So if my petrol is half tank & I fill up a nearby kiosks with
Octane 92 petrol (the kiosks also have Octane 95 & 98),  

Q1:
Does the 2 grades of petrol mix well or they form 2 separate
layers in my car's petrol tank?  If they don't mix, which one
will float to the top

Q2:
if they mix well, do we then get an average of Octane 96?

Q3:
Any degradation / adverse effects of mixing the 2 petrols?

Trending Tech Everyone Should Know About - My Thoughts
I've been thinking about this subject for a few days now, trying to come up with something unusual. But the thing that keeps coming to mind—even though I feel it's an obvious answer that everyone already does know about—is Artificial Intelligence & Machine Learning.

Why? Well first, it's technology that impacts everyone, regardless of how involved you are in the tech industry. I've got little doubt that we're right on the cusp of major social change as a result of machine learning—change as significant as the Industrial Revolution. We've got self-driving cars inevitably hitting the mainstream in the near future. There's cancer detection systems that are faster and more accurate than human analysts. AI systems being trained to defend against cyberattacks. Movie dialog being written by algorithms. The list goes on and on...

And second, while these advancements will absolutely push us forward in exciting new ways, they'll also destroy many jobs. And while that job loss can be terrifying, AI opens us up for entirely new sorts of jobs, major changes to the way work is done, and more that we can't even fully conceive of yet.

Will most knowledge workers of the future become "bot wranglers"? Will some sort of universal basic income

Lyft has been making some exciting strategic partnerships lately - yesterday they announced a partnership with Disney, launching the "Minnie Van", and today they announced a partnership with Amtrak.

Do you have a preference between Uber and Lyft, and why? If you are an Uber fan, would either of these entice you to give Lyft a try?

Haven't used either one yet, but I'm way more inclined to try out Lyft for the same reasons as Alicia noted. Uber seems like they've really not treated drivers and employees well.

Plus, that Minnie Van is pretty awesome and looks like a lot of fun. I'm sure kids will get a real kick out of it! :-)

I used to use Uber because Lyft wasn't available here.  Now that Lyft is available where I live I use them over Uber every time (mainly because of the way they treat their employees, but pickup times are usually faster, too).

It's interesting that every Lyft driver I've had also drives for Uber.

Every once in a while I can smell my brakes on the front left burning and you can feel that it is warmer in the wheel well compared to the right side. It doesn't happen all of time though. I took the whheel and caliper off but, the brakes look fine and the rotor is still smooth. I am wondering if the piston on the caliper is freezing up sporactically. I took it to the dealer but, the tech said that he isn't finding a problem and of course the problem doesn't occur when I take it in so, I can't prove that it is happening.
 Could it still be the caliper or is there some other reason why I can smell the brakes burning and feel the higher temerature in the wheel well?

I'm programming Infineon TC29x Aurix Tricore Microcontroller based embedded system in 'C' language.  

Consider stack starting address 0x5000 0000.  The stack size is 0x2000.  

If I take current stack pointer minus 0x2000, will that create stack exception?  If yes, what might be 'C' or assembly language code that will achieve this?

My thought is if I subtract negative 0x2000 from current stack pointer or add 0x2000 to current stack pointer, I'll be outside stack and stack exception will occur ?

 I need to set program counter to illegal address, i.e. 0x00FF FFFC.  Can this be done with assembly language instructions?
 If yes, please instrument assembly language instruction that would set program counter to 0x00FF FFFC while code is running.

"Experts say that widespread hacks of cars may soon become a reality." In the very near future, I expect an extra upsell for a top of the line security package, in addition to the usual upsells, like leather or heated seats.

Intriguing... When it comes to handling security issues like the one described in the article, it sounds like the automaker either had a breach of their key code database and/or a bad process for authenticating duplicate key requests. I'd say the automaker should deal with fixing those sorts of issues just like they would a safety recall. A certain baseline of security is to be expected. Like, if there was a mistake in an old-style non-electronic key that meant the same key would work in all cars of that model... You'd better believe we'd expect the automaker to cover that cost of fixing it.

But just like a car alarm can be a security upsell, I could easily envision new high-tech security add-ons to help against potential theft. Like maybe a car that would text you if it was taken for a drive at a time you don't usually drive it?

We are using TC29x Microcontroller. The flash size is 6Mbytes. There are Three banks, 2Mbyte each.

Program Flash 0 (PF0) is bank 1. Program Flash 1 (PF1) is bank 2. Program Flash 2 (PF2) is bank 3.

 PF0 address range is: 0x8000 0000 - 0x801F FFFF
 PF1 address range is: 0x8020 0000 - 0x803F FFFF
 PF2 address range is: 0x8040 0000 - 0x805F FFFF

 Where is Program Flash ECC stored. Is it within 6Mbyte ? Or is there additional storage space for ECC that we don't have access to ?

 How does Flash ECC work ? For how many bytes of data, how many bytes of ECC are there ? Whenever we write to flash, ECC updates? When we erase flash ECC updates?

 How is it possible to create Flash ECC Error ? Because everytime you write or erase flash, ECC will update?

hi Folks

i have been stuck on this issue for days and found no clue to fix it.

the navigation unit of my Toyota Prius makes some kind of clicking noise when it is powered on, finally i have figured out that the noise is related to its maps DVD. once the DVD disc is removed, the noise disappears. initially i thought it was caused by an aged DVD disc as the disc was used in the unit for years. i thought a new backup disc could fix the issue, but I was wrong.

now, all DVD discs can't be recognised by the navigation unit, whatever they are original copy, or burned backup discs in DVD -R, +R or RW, speed 1x or 16x, the same message keeps showing on the unit's screen. all discs can be loaded, but nothing works at all.

how can i fix the issue?

the car is out of manufacturer warranty, i am thinking if it is feasible to remove the navigation unit and clean it myself. If yes, how?

thanks heaps in advance,

bbao
