How about Streetview, and webpage indexing?
The only reason anyone should ever used iTunes is if they are forced to (they own an iPod or iPhone) or if they are an idiot.
I have an iPod Touch. Although a lot of Third party programs can sync normal iPods, most can't do iOS devices without iTunes drivers. Although it requires iTunes drivers (which there's ways of installing without the whole stupid program), I use CopyTransManager to sync music and videos to my iPod, and iFunbox to sync files with apps.
Only free as in beer, but a lot better than using iTunes.
This is why I use EasyPrivacy list in adblock plus to keep Facebook from getting that info. They know you read a page if it has a "Like" button on it.
Seems like they should have split up the load to a smaller microcontroller. A cellphone under full load uses what? 5W? My Netbook will use 10W. Lots of computing power to be able to sit and wait for an app to connect, or a keyless entry system.
Don't know why this is rated Troll. Based on a quick Google check the voltage of EVs is typically in the range of 380-400VDC, obviously with lots of current available. Working in an industrial environment I have seen not only accidents on 4160V, but 460V. Out in our world meters have class ratings, and are much safer than a no name meter from Walmart. A Fluke 373 is less than $200 and is CATIII 600V rated, and CSA / UL listed. Is your cheap meter?
Did they have a really fancy multimeter or was it just a piece of shit digital multimeter?
I inherited an Ideal brand meter at work. Many people swear at these meters. On a 480V circuit I was measuring 380V. I got someone else's newer Ideal meter. 380V. I got someone's Fluke meter: 475V. Once someone at work was so pissed at their Ideal meter that they threw it from a scissor lift while measuring a lighting circuit.
On a more serious note, one benefit of modern (quality meters) is the voltage class rating (eg: 1000V Class III rated meter) means the meter won't blow up if you connect it to 480V while it's set to Ohms. Not necessarily the case of the unrated meters sold at Walmart. Though the rating won't help you if you connect a 600V rated meter to live 4160V, or 12470V. . . Apparently people at work have tried in the past. . .
How about something similar that perhaps goes into the headphones jack of a cell phone to add LED notification to THAT?
Blackberry got it right and while a smattering of other phones include notification LEDs, it's very rare.
Nexus One, Nexus S, Galaxy Nexus, Nexus 4, Nexus 5, Galaxy SIII, S4 are popular phones that include it.
1) Commercial buildings, like that school, must have minimally 20 Amp minimally circuits- never 15.
I work in an older industrial facility. All the old crap (1960s-1980s) typically has 15A circuits, with a lot more receptacles per circuit than the newer additions. That said it looks like this school dates from 2006, so it should have 20A circuits.
I doubt it will be huge.
My company (largely) still runs Windows XP. When I started 3 years ago I inherited a laptop with a Vista license sticker (but XP installed). When the lease refreshed a few months later it was replaced with a laptop with a Windows 7 license (downgraded to XP).
We are only now starting to migrate workstations over to Windows 7, and some of the applications I use will keep me out of the group being upgraded (for now). Likely my machine will be refreshed again, and I'll be issued one with a Windows 8 licence, downgraded to XP. Although OEM copies of Windows 8 don't allow downgrade rights to XP, if the machine is covered under volume licence, or software assurance, it will be eligible to downgrade to XP.
So many people probably already have machines capable of running Windows 7, and already paid for the licence, they just aren't using it due to "software issues". End of life of support should push a drive to upgrade business OS installs though. Though I don't think the risk of unpatched XP machines is as grave as it's made out to be, as long as web browsers, shitty plugins (Java, Flash, Adobe reader), and AV software receive updates.
Being less secure (recovering data without the account password) is a feature?
Even on a desktop / laptop if secureboot were "forced", you could take the hard drive out and put it in an enclosure on another workstation and read the data. Having the option to use a boot disc (Be in Linux or WinPE based) is a lot more convenient.
Hell you can still use a boot disk to recover data off a locked out Linux account.
You can install The Windows 8.1 Enterprise Evaluation version for 90 days:
Anything is possible, and accelerator pedal and throttle position sensors have redundant channels and the system is supposed to fault to a power-off state (typically a fast idle limp-mode). So your scenario wouldn't happen if there was an erroneous signal on one channel. It would have to have the ECU believe WOT was requested (even though both channels are at idle). Say the ECU's memory got corrupt and the value in memory got overwritten. For the car to actually go out of control and accelerate, everything else would have to work as designed: crankshaft position sensor will have to work to know when to inject gas and fire plugs, fuel injectors and spark plugs would have to continue to fire properly, all your O2 sensors MAF, etc would have to continue to operate properly to give a correct fuel/air mixture, fuel pump would have to continue running, transmission solenoids (in an automatic) would have to stay engaged.
The hydraulic pump for an automatic is on the input shaft (engine side) so the engine must be turning above a certain minimum speed to provide hydraulic pressure to allow the clutches and bands to engage a gear. Hence why trying to push start an automatic doesn't work. A torque converter does transmit torque back through to the engine, that's why engine braking works in an automatic. In the case of push starting, because the engine isn't turning, there's no hydraulic pressure to engage a gear. Some of the first automatics did have a pump run off the output shaft to allow push starting.
Your Voyager would of had a 3 speed hydraulically controlled automatic. I had a similar transmission in my '97 Neon. When I had the car, I once tested this theory. While driving down a long hill, I shut the ignition off*. The engine was still turning, I still had power brakes, power steering, and if I pushed the accelerator to the floor the transmission would downshift (though obviously the car didn't go any faster). Turn the ignition back to on (not start) and everything picked up just as it should. This wouldn't work in a modern car as they all (typically) have electronically controlled hydraulic automatics, so if you shut off the ignition, the solenoids would all drop out, bands and clutches would release, transmission would be in neutral, and the engine would stop.
As far as why your Voyager stalled, transmission of the torque back through the torque converter isn't going to be 100% efficient (I'd imagine possibly more so since it's going "the wrong direction"), so if the engine RPM is low (say minimum speed in top gear), it might drop the input shaft speed below that required to provide sufficient hydraulic pressure. You wouldn't see the stalling at high speed because the engine would be turning faster, so it might be able to "ride through" the fault before the engine stopped because it has vehicle momentum, not just engine momentum. The torque convertor would have possibly locked up then too, providing better ride-through.
*Someone is going to get upset that the steering wheel could lock. The ignition was moved to "OFF" not "LOCK", and it couldn't be moved to LOCK because the shifter wasn't in park.
Another test I did in that car was stop at the top of a steep hill (facing uphill), and with the car in DRIVE, take my foot off the brake and allow it to coast backwards. At somewhere like 5-10 km/h the car started bucking a bit (like a manual about to stall), then the engine did stall, transmission effectively went to neutral and it started picking up speed quicker. Again this shows torque will be transmitted back through the transmission, to the engine.
On another time with that car, someone driving it meant to shift to neutral while going ~40km/h, and overshot and went into reverse. The engine immediately stalled and the car kept rolling in neutral, though there was no apparent damage from this stunt. Lesson there was you can normally shift to neutral without having to press the button. Also electronically controlled transmissions will not engage reverse if you're moving so fast.
I think he may have been reappropriating the term "drive by wire". It would not be in reference to the ford "drive by wire" system (electronic control system that appears the same as a traditional mechanical column). More likely meaning that power steering and power breaking require the engine chip to be functioning to operate.
And he is correct that those subsystems cut out with the engine. My vehicle recently had a vacuum leak. The engine stalled out as I was breaking. No power steering, no power breaking. It was not a good situation. The car behind me very nearly plowed into me when the light flipped to green.
The Ford system (Active Park Assist, Lane Keeping System) don't replace a mechanical column with something that looks like a column. These vehicles (and most new vehicles) have electronic power assist steering. Active Park Assist just commands the assist motor to turn the wheels. Mechanical linkage is still there. Turn the engine off and you can still crank the wheel over. The system normally works by monitoring how much torque is being applied to the wheel in which direction, and adding assist to bring that down.
I'm not aware of any current mass market vehicle that uses something other than vacuum assist for the power brakes. There is electronic features like ABS, electronic brake force distribution, etc, but even with these systems, the booster normally stores enough energy for 1-2 assisted applications with the engine off.
Even with conventional hydraulic power steering, mechanical throttle linkage, and vacuum assist brakes, when the engine stalls there's no more assist, so it's a moot point.
No need to roll out of bed that day. Leave the stop light for chumps.
Some of us do need to work, or otherwise leave mom's basement for the day.
