The avionics system in the F-22 Raptor, the current U.S. Air Force frontline jet fighter, consists of about 1.7 million lines of software code.

These are impressive amounts of software, yet if you bought a premium-class automobile recently, "it probably contains close to 100 million lines of software code,"

Late last year, the business research firm Frost & Sullivan estimated that cars will require 200 million to 300 million lines of software code in the near future.

Ive got a car that doesn't even have a transistor in it.
Electromagnetic Pulse resistant...

(except when i plug the laptop into it haha)

I can only grimace thinking about the code base in
some of these code cars and wonder what happens
when your car gets nimda attacked or something
and you get like a 500 internal server error or something
when you go to start it. Technology is just getting invasive
and into EVERYTHING for all the wrong reasons...

I mean in five years, marty mcfly should be hoverboarding
but we cant even do speech recognition worth a shit still.
Its gonna be until after jobs and gates die and the corporate
dickheads take over the superpower companies before new
tech is developed in a different way.. So much of what we
have going on branches from a 6502 put together by these
guys in a garage (not leaving wozniak out..) but still i mean

What kinds of changes do you think will happen to technology
after jobs and gates die?

>500 internal server error

I do not have a problem with new or exotic technology (see my house) but I do feel that the on-going binge of replacing any & all mechanical and electro-mechanical systems with electronics & firmware is out of control.  Some very worthwhile innovations like airbags require them, sure. But do I really need fore and aft driveshaft sensors to monitor the engine rpm and continuously compare that to the driveshaft rpm to tell me that the transmission is slipping? (BTW, replacing the sensors that caused the false-positive which then forced the transmission into LOW gear while I was 35 miles out in the hinterland was $200 including the diagnostic session on the dealer's computer.)

Whats really fucked up is those cars all have a code
you can enter without the machine like 'up up down down
on the window switch while holding the door open and
double stomping the accelerator in sync with a certain
indicator light' and it goes away... 200$ to the mechanic.

Yah, i worked at an auto shop last summer.  The scam is
outrageous.

Brakes, for instance.... WTF do I need computer-controlled brakes on a non-hybrid?  Give me an oversized 4-wheel disc system.  If you want to upscale me, make the master cylinder out of 306 stainless (one of my buddies retrofits these into Land Rover Series 2's -works great, lasts forever, looks awesome).

>hummer

A couple of years ago I bought a low-mileage 1994 F150 for a maintenance truck for one of our real estate businesses INSTEAD of a new model because the '94 was relatively was low tech.  This past weekend (late Friday evening. out on the barrier islands where everything costs a fortune to get fixed) it wouldn't start. No power to the starter. My first thought was oh-uh, computer module gone bad, must get tow-truck. Then, NO! It's a '94, Probably has a starter solenoid.   It did. I bridged the terminals with a screwdriver and drove it home.  Replaced the solenoid the next day for <$20.

I know a mechanic who plants gps-text message tracker devices on customers
cars and then hell go find the car somewhere remote and crawl underneath
the car and short out the solenoid on the starter with a rubber handled screwdriver..
Or wreak havoc with the dewalt cordless and just the right few sockets...

 ... then he just goes back to the tow truck and waits for them to
 call the 'free towing with repair' number on the keychain he gave them previously
and waddya know the parts in stock... i can get you back on the road right away,
will that be cash or check.

I had to buy a new car and move before i stopped having so many
car problems.

That sounds like a mechanic that needs to be fixing old engines in the prison yard.   Police
