And everybody knows that males don't ask for directions.
Google Maps navigation is the best thing to happen to us males. No more do we have to stop and ask some stranger for directions, or worse, get yelled at by our wife/girlfriend for being so reluctant to ask for directions when we're out and lost. Instead, we just whip out our smartphone, tap in our destination, and get Google Maps to show us how to get there, whether it's by car, bus, or walking. It's really a godsend.
Exactly. The modes of transport are entirely different. Buses don't always travel in a direct route, and in fact, frequently travel in an extremely indirect route to get more passengers in certain locations. Whether you're a transit rider or a cyclist or a walker or a driver, the only thing you care about is time. But if you're driving a car, the fastest route may be longer than the fastest cycling route, because you can take advantage of high-speed roads (highways) that cyclists aren't allowed to use, even if that adds a few miles to the route. If you're taking a bus, the fastest route may involve taking multiple buses and a circuitous route that no one else would bother with, because that's the only route the bus travels to get there.
Transit riders' perception is totally different too. They have to worry about getting off at the correct stop, so all they care about is the names of various stops, and then how to get from the bus stop or subway station to where they're going. They have no reason to care much about all the roads in between the two transit stops.
This reminds me of my Health class in high school. At the end of the semester (it was a 1-semester class only, usually the other semester was used for driver's ed), the crazy old teacher gave everyone a grade on their notebook. His method for determining the quality of your notebook? The number of pages in it. I got a bad grade, because I wrote small and had few pages, even though I wrote down everything important. The guy next to me had giant writing, and filled up a bunch of pages just writing "Health is cool!" and got a high grade.
You think Universities would be more intelligent in their rating of professors than some idiotic old gym coach, but apparently not.
The problem is, you don't need 40W to run a computer. Look at all the other posts here, where people are posting what their regular laptop computers consume. Typical numbers for dual-core and even quad-core x86-64 laptops are well under 20W, and even under 10W, and that's just idling, not in a sleep state. If I can buy a Thinkpad laptop and let it run idle at less than 10W, with WiFi connected and responding to SSH, then why the heck does the Tesla need 40W when it's supposed to be using an ARM-based computer, which should theoretically need even less power than a typical i5-based laptop? Anyone have the idle power consumption of an iPad? It's probably a lot less than 10W.
A 1% self-discharge rate on an 85kW-h battery works out to a constant rate of 1.16W according to my calculations. That's pretty insignificant really. So where's the other 43.8W going? Something's really off here. We've covered the self-discharge rate (should only be 1-2W), and we've covered the computers in previous posts (should be no more than 10W), so something's really off here.
Sure they are. Lots of high-end cars have dashboard computers.
In addition, tesla must stay alive with WiFi/3g to report battery status.
My mobile phone, and every tablet made, can stay alive with WiFi/3G without using anywhere near 45W. A typical Core i5 laptop can do this with less than 10W, according to someone else here. 45W is what you need to keep a server or very powerful desktop running with multiple hard drives.
AC-DC conversion does incur a loss, but if the batteries are topped off, the float charge should be pretty minimal, and the extra losses through AC-DC conversion only add, at most, 10% to that if you have a decent converter. Someone else mentioned around 9W to keep the batteries topped off due to their inherent self-discharge rate; there's no way your AC-DC converter is going to have a 20% efficiency (if it does, it's a POS).
Well if they're using an ARM chip(s) and mobile GPUs (which should be shut down when the display is off anyway), then something's really wrong, especially if you can run a dual-core i5 laptop at 7W (display off) like another poster here said.
That seems to be the case. Features like keyless entry are apparently run by that computer and so it never goes into a deep sleep state. Even then, 40W is pretty extreme. A typical high end mobile phone with wifi and 3G connections and background sync is more like 1 or 2W maximum (averaged over a day, of course).
Yes, but a mobile phone can't drive dual large displays with Nvidia GPUs; that system is surely comparable to a typical x86-64 desktop system, and one of those would easily use 40W at idle with the displays off. x86-64 CPUs are not low-power like ARMs.
It sounds like the problem is they didn't design this system for power management very well; they should have had some sort of multi-CPU system running both a low-power ARM and a high-power x86-64, so it could keep the ARM running while "off" to manage functions like WiFi/3G, background sync, and keyless entry, and only powering up the big CPU when the car (and its main displays) is "on". Of course, this would be somewhat complex, and require some fancy software architecture since ARMs aren't binary-compatible with x86-64s.
Self discharge on the main battery should be on the order of 9W.
I started thinking about that after I wrote the previous comment, so this answers my question assuming your number is correct. A big-ass battery pack like the Tesla's surely has a significant self-discharge rate, but 9W isn't too bad, and sounds about right considering how fast my cellphone batteries self-discharge (I have spares I keep for days when I'll be using my phone a lot and won't have access to a charger).
Well that's what you get for being a lesser-developed human, Cro Magnon man. At least you're better off than the Neanderthals. There's no telling how bad their singing was.
but if you didn't want to sound like Kenny, you'd also need high quality microphones, sound damped recording studio,
You've never actually needed a sound-damped recording studio. Lots of big bands have recorded and sold "live" albums for decades now, and those obviously weren't recorded in studios. As long as they're recorded from the soundboard, and mixed well, they can sound spectacular (though the vocal part does sound a little different than a studio recording for obvious reasons). If you don't mind your song sounding just a bit imperfect, you can skip the sound-damped recording studio.
Of course, the sound-damped studio isn't exactly expensive to do either: you can do it on the cheap just by buying a bunch of foam and building a box in your garage and lining it with the foam, and putting your nice $500-1000 microphone in it. Or maybe just go into a big field on a sunny (and more importantly windless) day and record the vocals there (wide-open space = no echoes).
Actually, it's shockingly high. I'm a Tesla fan, but this seriously makes me wonder what's eating up all that energy while the car is supposed to be "off".
The Tesla is not the only car out there with "all kinds of gizmos built into it": every high-end luxury car, from the likes of Mercedes, BMW, Cadillac, etc., is loaded with electronic accessories. However, all those cars run on gasoline engines, with a standard 12V battery to keep things alive when the car is "off". No regular car would be able to start its engine in the morning if it were powering a 40W light bulb all night.
So what exactly is the Tesla doing with all that power? Even if it's keeping a WiFi connection alive, that shouldn't take much power: my little smartphone can do that for days with a puny little 5.6Wh battery. Are they running the main computers at full power? It really shouldn't be that hard to put them into sleep states when the car is off. It sounds like maybe they badly architected the computers in this car, so that they could never go into power-saving sleep states and still keep the WiFi/3G connection alive, something every modern smartphone can do with ease.
Exactly, and that's a great point about other people: if you've already piped up and complained to your boss about the problem, and no one else has, if word gets out somewhere about this problem, who do you think is going to be fingered for it? You, because you were the one who obviously thought it was a big problem before.
No one is going to appreciate you for publicly identifying security vulnerabilities on some private company's website. This isn't worth ruining your entire career over.
The important thing to remember about whistleblowing is: if you do it, you will never have a job again. Weigh that cold, hard fact against the severity of whatever it is you think people should know about. If lots of people will die if you don't, then it might be worth it to you. Website vulnerabilities? No one's going to care. No one even cares when millions of credit card numbers or other private details get leaked/hacked from some website.
The US really does not resemble either the DDR or USSR in any way.
Of course it does, it just hasn't gotten really bad, yet. The US is absolutely an imperialist superpower, just like the old USSR, using threats of force to get other countries to bow to its will and routinely sending its army to invade other countries to control resources and establish hegemony, and now it's spying on all its citizens just like the Stasi did in the DDR. It's not a big step from there to abusing all that power and routinely oppressing regular citizens.
No, don't leave. Find a new job, get an offer, accept it, then leave.
It's extremely unlikely they're going to get into any criminal legal trouble in that time, and even if they do, it won't be traced to you. Get out and just find a new job. Don't try to be a hero: America hates whistleblowers, and there are zero protections for them here. If you reveal the problems, you'll never get a job again, because you'll be seen as a liability. Anyone who's ever blown the whistle on anything will tell you this. It just isn't worth it. The only way to blow the whistle is to do it anonymously somehow, so it doesn't taint you with a reputation as a "rat fink".
If the past is any indicator, the judge is going to tell the DOJ to EABOD.
So what? The DoJ is under no obligation to listen, or heed the Judge's ruling. Remember what happened the last time the Judicial Branch tried to tell the Executive Branch it couldn't do something? The Trail of Tears was the result. The Judicial Branch has no ability to enforce its rulings at all.
The people in 1933 Germany probably thought things wouldn't get so bad either.
And it's not going to be Arab-Americans who are hurting, it'll be regular, everyday Americans. It's not Nazi Germany the US is becoming like, it's East Germany after the war was over, all the way until ~1990. The Nazi regime didn't last long, but the East German government lasted for about 45 years. It didn't oppress some disliked minority, it oppressed everyone; did you forget what happened to people who tried to escape? Restrictions on travel and movement are standard with oppressive Stalinist regimes, and the US is resembling that more and more every day (though a little different, since a lot of the power rests in corporations rather than a central government).
Yep, it's funny how everyone acts like the Republicans are the reincarnation of Hitler himself, yet it's really Obama and the Democrats who are in charge now and are fully responsible for the stuff that's going on now. You can't blame the TSA and NSA and their shenanigans on the Republicans when a Democrat is in the Oval Office signing executive orders.
Yeah, Mir is crap for several reasons: it's not an open process (as you complained about), it's being unilaterally forced by a giant, unfriendly gorilla as you said, and it distracts from Wayland, which is a piece of critical infrastructure that everyone else in Linux-land (including all the other major distros, and including all the people who were important developers at X.org including Keith Packard) has agreed is necessary and is working together on. The latter part is especially bad because, unlike infrastructure like systemd/upstart/sysvinit, the display system is intimately tied to the display drivers, so drivers for Wayland won't work for Mir and vice-versa, and we've had a hard enough time getting the GPU companies to support Linux over the years with only one display system.
Wayland's development IS an open process, and is being done by developers from several different companies. What is this "giant, unfriendly gorilla" you talk about? Canonical has nothing to do with Wayland; that's something lots of people have been complaining about.
Again, this isn't the norm. It's just like the other responder with his case of the Buffalo teachers' union and their wacky health plan. Find me some examples of health plans in the private sector that include this stuff today (not in the 80s).
