120v @ 15A is 1800 watts. As I said, I was able to measure the wattage being delivered at the end of my 100 foot 16 gauge "home depot" orange extension cord connected to a space heater and found less than 900 watts being delivered to a load that normally pulls 1750. The voltage had also dropped below 100 volts.

Its possible that the Tesla simply won't charge at all if the current or voltage on the line becomes too low. In this case, it would be "plugged in" but not charging.

Edit: Lets figure it out: Range=244mi. Battery capacity=58kWh. So: 5 miles takes 1.086kWh. 10% is lost in chemical conversion so we really need 1.207kWh for those miles. We pull at a rate of 1.8kWh/h from the plug. So 600 watts or so is lost elsewhere. We know the "always on" battery cooling system alone takes around 150 watts. Its not that far fetched.

Edit: I deleted my comment below where I calculated the cost of keeping the car on standby because I don't think I made clear enough (and didn't want to type it all twice) the difference between the actual discharge rate of the battery and the amount of power required at the charger to stop it. It just seems to take a lot of power at the charge port before any gets to the battery. The battery seems to discharge at an average rate of just 30 watts, but it seems to take a much, much greater amount of power input to prevent this and failing to provide this power has dire consequences. Why?

It's harder to debug and extend a bitmap, and in the real world, single service instances don't scale infinitely, more layers are added. You will never have enough back-ends behind a single proxy for the time spent parsing to be measured.

This is a textbook premature optimization. You're designing for academic purity instead of the real world.
This is one concerning I would NOT want hanging over my head every time I left the car for an extended period of time :-\

After reading that I looked down at the desktop I'm writing this from.

I laughed.

Desktops are by no means "rare". Cell phones have just become ubiquitous, theres a difference. (Laptops too for that matter.)

One of my problems with current generation laptops and netbooks (Besides costing almost twice as much for the same performance.) is that despite being "mobile" computers I end up having to set it down on a flat surface every time I want to use it. Walking around and using your laptop at the same time? Not going to happen. (Unless you buy one of those chest-strap things I saw in the first splinter cell...) The OLPC solved this pretty elegantly with the handle on the back, which is made just perfectly so that you can actually hold the computer with one hand and operate it with the other. (This mainly works because the OLPC is more netbook than laptop.)

And then you get two more problems I have with the laptop form factor: Trackpad vs Mouse, "Keyboard" vs Keyboard.

Trackpads, even when you have a responsive one, are awful. They're like touch screens, but not as cool. If you have anything on your hands, it gets on the trackpad when you use it. Trackpads are too slow if they're set at a speed where your mouse can actually point, and uncontrollable if the speed is turned up.

The "Keyboard"s that comes with most laptops barely qualify for the word. Traditional desktop keyboards can have keys with a height greater than five millimeters. (I'm exaggerating obviously, but laptop keyboards are very flat.) and I much prefer this to keyboards that feel like I'm tapping on a piece of plastic cardboard. I'd almost rather forgo the keyboard entirely and just push down on the little gelatinous circles underneath directly. And don't get me started on replacing one of those keys if they break. (Which they often do.)

And no, touch screens aren't the answer. On laptop screens, touchscreen == dirty display. I already have a rant here about touch screens on mobile devices. On displays bigger than a laptop, you better not have been planning to sit more than an arm's length away from your monitor. Oh right, the future doesn't have big screens in it.

Desktops might not even be common in a decade, but they'll be there. If for nothing else because theres people like me who still like to sit down to a (awesome) computer setup.
This is akin to leaving the headlights on when the car is turned off in a regular car. You're asking for trouble. (though not to the tune of $40,000)

When the car is turned off, there should be some kind of indication of how long it will take to brick the thing. If that indication is days rather than weeks, it should yell at you. Loudly. At least that way all owners will know of the threat. The car will educate them. (important, because they probably won't RTFM)

Although I'm sure you could still end up with the odd user who leaves the car with a three week brick time, receives no loud warning because of the significant charge remaining , comes back five weeks later and curses Tesla.
I don't think cultural elitism or musical hipsterdom is a useful response. There's major label music that easily matches the artistic merit of anything you could name, and while it largely would have existed with or without major label support, it would not have reached as many people or received the same production values.
Failing open would be bad, a "unscrew this small panel and pull this switch" would be fine.

My car is old Saab and there are places to move aside bits of trim to manually operate the sunroof and fuel tank cover if the battery is completely gone.

The boundaries of what defines a derivative work is a bit fuzzy, and how much you need to take from a work in order to create new work that would be classified as derivative is open to debate/common law.

Suppose that HP holds a patent related to the keyboard layout in webOS, of which the source code of their implementation is released under the Apache licence. If Apple took that code and mashed it into iOS, it would (I believe) clearly be a derivative work and protected by the licence. But suppose they didn't look at the code (or any material released by HP under the Apache licence), they just saw a picture/read a description of it/used it on a device and implemented it based on those experiences; in this case I think it's difficult to say that Apple's implementation is a derivative (and therefore protected) because of the lack of connection to the Apache-licensed work (except that their code produces the same runtime effect that HP's does, which I don't believe is necessarily covered by the Apache licence as they are separable from the original work).
At long last, I can see how much Whuffie people have!

You could take that argument as far as you'd like. He used oxygen to help him commit the crimes, thus we should take away his oxygen.

No, the internet has directly helped him commit crimes. It is a tool he used. As it is non-essential, and we may disagree on that point but the courts are agreeing with me, then it is logical to remove his privilege.

I don't believe my rationale is asinine at all. I think you're equating this man's freedom with the protection of the internet itself, and are overstepping your position because of it.
The pack is 53kWh according to wikipedia and discharges in 11 weeks from full according to the article. Unless I botched a decimal place, that is a 29 watt idle load. (53000 watt hours / (11 weeks * 7 days/week * 24 hours/day) ). In perspective, that is about the same as 4 night lights.

Clearly there is about 20 times that much power available at the end of a 100 foot extension cord in a standard household outlet.

Failure modes available:

• Was not actually plugged in.

• Was unplugged then plugged back in much later, possibly unbeknownst to owner. (Someone in my household unplugs my DVR to use an outlet. Grr.)

• Was on a switched outlet. (I once bought a new drill over that. Who knew one of the duplex outlets was switched and the other not? But the new drill wasn't $40k.)

• The Tesla charger could have a cutoff where it stops charging if unable to pull X amps where X is somewhere between 7 and 15. This could be either intentional or unintentional. Brown out protection circuitry, if needed by the design, could do this. They also might fear they are setting your house on fire by dropping 800+ watts somewhere in a wall and shut off.

• Broken charger.

• Broken extension cord.
It was :)
How is the slowing down of list block after the cross/check image was shown done? Read through the github code, still can't pinpoint the code that does that.
You were probably downvoted because you didn't read the article.
That's because a 16 gauge extension cord isn't supposed to supply 120v @ 15A. A 16 gauge cord is only good for around 10 amps.

Which means you have a point. If the owner in question plugged the Tesla supplied 120v cord in to an additional 100-foot, 16 gauge cord, they might have a net loss situation on their hands.

Er, no, this is probably wrong. The voltage drop is due to resistive losses in the long (and skinny) cable, and the resistive losses depend on current flowing. So, unless there are some weird effects due to the car's electronics, you cannot stop the charging, only slow it down.
Thanks for adding the clickable link.
the demo is your advertisement for the framework. It should ahem demonstrate the benefits of using the engine. Don't you think? If the demo looks bad, the framework looks bad (Often regardless of its actual quality)
I should be able to calculate this... but what's the resistance of that cord then? That's quite a voltage drop.

EDIT: Wow, apparently this is pretty typical and expected as per this calculator: http://www.csgnetwork.com/voltagedropcalc.html

I'd prefer the government stay out of it all together. Producing vehicles isn't what the government is for.

Second, using a 2500 pound car to transport a 150 pound person 15-20 miles to work every day is incredibly inefficient any way you look at it. If the government is going to be involved at all, it should be to promote walking, cycling, and public transportation. Researching more efficient cars is like trying to replace arsenic in drinking water with mercury - maybe it's not as bad, but it's still bad.

Third, if people were serious about saving the environment and reducing pollution then they'd start living closer to the places they need to go, and stop driving so much altogether. They're not doing that, so I don't think the interest is there.
I would point out that both the Model S and X may very well have the circuitry to completely disconnect the cell pack at something below 10% actual charge (not displayed charge). I'm also really wondering how much of this is self discharge, and how much of this is poor load control of the standby electronics.
For the record, "This presents a troublesome, albeit interesting, avenue for further data aggregation, which could be used to target ads or sold to third parties" is a lousy comment too. The problem is not the form, it's the content. What do you mean, it's "troublesome, albeit interesting?" That is totally devoid of insight.

The reason I read a comment thread is because I want to find things that experts have to say. If grellas has some comment about the applicability of privacy law to the monitoring of someone's immediate surroundings, then great, let's hear it. But if I don't walk away from the comment having learned something, I would rather it not be there.
It's a bug in the same sense that internal combustion engines will begin to have problems if their motor oil is not changed. It's inherent to this kind of battery.
Elsewhere in the thread I calculate the life support draw at 29 watts from available data (53kWh battery, 11 weeks to idle to empty). I think you can afford the $100 if you have a Tesla.
That's awesome, really exciting to know that he actually started experimenting with the tech.

Yeah, I've been told it falls under the standard AppleCare warranty if this happens to anyone. (Likewise with fraying of charger cords).

Personally, I don't see why it's "your fault". I've seen it happen many times, all you need to do is let your computer drain completely and leave it for a few days (not months as some people have stated in this post). Although I'm sure it says something about it in the manual somewhere, it's hardly common knowledge that this is something you need to be careful of.

Unlike a laptop, the Tesla was never designed to be run while plugged in. Combined with the fact that they arent designed to hit zero battery. This is an easy oversight of design, where the laptop can run directly off of wall power not due to fix the problem of a dead battery, but to provide less stress on the battery while being used and plugged in. A usage case that does not exist under normal usage of a tesla.

Additionally. Do we know that it is actually impossible to engage tow mode while plugged in? That still doesn't solve all cases of having to manually move it.

So the charger sees the 120 V, decides to begin charging, current flows, and the voltage drops. If the voltage drops out of range, the charger aborts because it's out of design spec and/or there's a significant amount of power being dissipated, probably by resistive heating (i.e., risk of fire).

This is probably necessary to achieve UL rating.

The prosecution took it that far and the judge does not understand the implications of Internet as a necessity. I even highlighted that it restricts many needs to function as a member of society. The reality is that there are electronics that can easily tap into the World Wide Internet, which gives credence to my argument that his electricity should be shut off along with all electronics (may be battery powered) as part of the effort to prevent access to the Internet.

The Internet did not help him commit crimes, it's a neutral platform. They are merely carriers just like roads, servers, etc.

> I think you're equating this man's freedom with the protection of the internet itself, and are overstepping your position because of it.

Nope, I'm talking specifically about the human right to the Internet due to the necessities, abundance of electronics with access to Internet, many potential outlets and most of all; unenforceable to prevent access. I think you're overstepping your position again by implicating me with other positions when I've been quite clear.
I am one of the co-founders of Clickpass and I think this is a great move.

I wrote the HN code in about 2 days and I was learning lisp/arc so it was awful code (RTM did the openID part) and literally no one has touched Clickpass code for 2.5 years. The fact that it still works is always surprising to me :).

Also I think Oauth beat OpenID hands down.
No, leaving the headlines on on your car is unlikely even to ruin your $100 car battery. You'll just need a jump start.

That is true, but I'd say swiping backward is about as intuitive as the now-famous "pinch-to-zoom" gesture: once you know it, it makes sense. It just takes warming people up to the idea; a luxury Palm didn't really have.
They have things completely backwards. Github didn't make coding more decentralized, Git did. Github made it more centralized, though in a mostly non-binding way thanks to Git.
Why what? Why we are happy with it? It is easy to implement and the people creating it are smart. They've done a good job so far, I see no reason why it won't be successful in the future.

The browser integration will be amazing when its ready, but until then, it is the closest thing to FB auth without requiring FB or people to give up their friends list or other information they are concerned about.

I'm not sure what 'crucial component' you are talking about, but we are just using browserid.org.
Did you mean "no one has touched the code in 2.5 years?" If so, then that is indeed, surprising.

And yes, OAuth did beat OpenID, but they're not really the same kind of thing.
