Sure. If you'd point a space-based gamma ray telescope at Earth, and said telescope be sensitive enough, you'd surely see the "glowing" truck. I'd think the resolution and sensitivity of such telescopes is such that you'd be lucky if it would be a glowing pixel, though. It's a simple enough matter to check how many gamma ray telescopes are pointed down and used for land surveillance. My bet: zero.
You do realize that a Thunderbolt port on a Mac lets you attach pretty much all of your peripherals via one cable, including PCI and PCIe cards? It's even better than a dock, because it's standardized.
Probably sooner rather than later someone will manage to run it using wine with cpu emulation. Usability might suck, but technically it wouldn't be that hard.

I wish ULA was publicly traded. I'd be shorting the shit out of them right about now:) The parent companies' stake is too small to bet big time on, not yet...
But they are playing fair. The old-space industry is boring. I wouldn't want to work for them, and I'm sure many way more clever people than myself wouldn't work for a lazy corporate behemoth either. There's only so much fun to be had in a stuffy cubicle. I mean, heck, these days you can't even have a nice secretary to look at. Something is to be said for work conditions impacting the creativity, productivity and general willingness of the workforce to, you know, work there. The results - overpriced stuffiness - speak for themselves. I couldn't even fucking tell what ULA's mission is. With SpaceX, it's quite obvious: they want to innovate, they want to do it better and cheaper, and they want to reinvest the profits into bold new stuff nobody else has done before them. You don't need to read anything to know that - their actions stand on their own.
SpaceX started merely as a loss-making venture poaching ex-government and contractor employees, and taking government money - it really had nothing meritocratic to bring to the table.
You call it poaching, I call it free job market. You call it "nothing meritocratic", I call it an exciting work environment. Work for legacy space transport providers is outright boring and mindnumbing, like work for any big corporation these days. SpaceX cares about their employees a bit more.
Even when disengaged, this adds a small amount of drag to the engine.
Yeah. And to evaluate such drag, just realize that all of the energy is dissipated as heat. We're talking a rolling friction dissipation in the belt and the bearings amounting to maybe 10-30W. Maybe. Things would get hot real quick otherwise. It doesn't matter, you won't measure it on the dyno, you won't see it in your lap times, unless you're driving a Geo Metro.
The electric AC will have lower efficiency when it's running by definition, and its losses will easily outpace any losses due to drag. They will be only present when it's running, but overall they'll be relatively gigantic. A good alternator may be 85% efficient. A compressor motor may be 85% efficient. Remember: they run hot. That's ~28% wasted energy. Since an AC compressor can be easily a kW worth of mechanical load, we're talking ~300W wasted when the compressor is running. It'd need to have a real low duty cycle (below 10%) to waste less energy than the all-mechanical counterpart.
There is no such thing as "full power steering", AFAIK. It is a mechanical drive (rack/pinion) with a hydraulic servo. It's a bear at low speeds, especially in heavy cars. Maybe if things are particularly worn out and the car is heavy, you'll be struggling up to 30mph or so. It should be OK after that. For lightweight cars at speeds you get when out of the parking lot, I can't see it being a problem.
Are you sure those are speed limits? If it's on a yellow background, it's not a speed limit, merely a suggestion. I have, frankly said, not seen a "curve" speed limit anywhere in the U.S. as of yet, but plenty of those yellow suggestion signs.
Depending on the vintage and implementation details, traction control may not be applying the brakes. Due to drivetrain inertia, it then won't be anywhere near letting you achieve ideal 0-60 times - it will be losing traction then overcompensating, as all such systems do. They have no way of compensating "just enough" since the engine and drivetrain response is vastly too slow for that. AFAIK, high performance traction control lets the engine develop slightly excessive torque, and bleeds it off through pulsed brake action, maintaining the wheels at a slight slip for maximum forward traction. It'll also detect slippery conditions and revert to zero slip, as that works better on wet pavement.
I agree about higher gear starts. I don't know how to drive a motorbike worth a damn, but when I was trying to learn on a friend's 250cc, I'd simply not use the first gear at all.
There must have been something else wrong with the car. A properly maintained car, at slow speeds on level pavement, should simply drive straight when you take the hands off the wheel, whether power steering is working or not. I check my car's handling by turning off the engine while going 60km/h or thereabouts, it should drive straight, and both the brakes and steering should work reasonably without assist. Yes, they'll make you work harder, but they will work otherwise just fine. Anything else means there's some maintenance to be done.
Wait, so that car loses steering merely due a to a fluid leak? WTF? Are you serious? I mean yeah, it gets harder to steer when you lose the fluid, but it should be steerable allright.
If you seriously think that an unloaded alternator has the same drag as a loaded one, I've got a perpetual motion machine to sell you. Wait, no, I've got a whole lot of them to sell you. Every new one much better than the predecessor, in fact.
Vampire-like? Huh? Are we dumb kids here or sum'thin'? This is beyond anthropomorphization, man.
The energy has to go somewhere. They have power management on that car, as well as engineering telemetry. They know exactly where it goes. Let's cut the bullshit. As far as I can tell from how it looks, the energy is needed for something. I don't know what, maybe the batteries have high leakage, whatever, but it's not like the energy evaporates. The power/charge management system needs this energy, and what they are fixing is not some random energy drain - they are trying, and failing, to fix the underlying cause that is not easy to fix. I don't know if it's a design issue in electronics, or a battery issue, or what. But one thing is for sure: they know exactly where all those kWh end up at, but they're failing at resolving it. If the drain was significant on cold nights, I'd say that it goes into battery pack heaters.
You do not actually own your car. You have a certificate of Title from the State that grants you exclusive privilege to that property, in exchange for an annual fee paid to the state. But, it is not, at the end of the day, "your" car to do with what you please.
What a load of bullshit. You don't pay recurring fees to maintain a title to a car, you dumbass. You only pay them to keep the car registered, and thus legal to drive. If you merely wish to own it without driving it, you pay the title fees once at the acquisition of the title and you're done. I hope you don't own a car in the U.S., because if you're confused about this, I wonder what else you're confused about. I hope you know what side of the road one drives on.
It doesn't matter that it mostly works. There's absolutely no guarantee it works consistently, or that the results are good for anything. It's a medical diagnostic service and it needs to be regulated like one. Case closed.
I've had a brush with LoJack-originated technology, and everything about it appeared super-shady. These days I use Orbicule Undercover. No subscription and you can verify the functionality anytime. Yes, it's not tied into the BIOS, but for your typical thief it'll be an effective countermeasure.
By reasonable I mean fuck yes I'd expect to argue as hell if they were hung up about me driving over the speed limit. I don't want to fucking get killed, mmkay?

Yeah, you see, but you're being rational about it. Others seem ready to be driven by unabated hate.
You do realize that a Thunderbolt port on a Mac lets you attach pretty much all of your peripherals via one cable, including PCI and PCIe cards? It's even better than a dock, because it's standardized.
You think they pay for SolidWorks, or in fact any CAD/CAM licenses in China? Ha ha ha.

Yep. Was available as an option on standard trim on Volvos even in 2000, IIRC.
