1. Teslas don't need oil changes. You know what's better than a great dealer experience for required maintenance? Not needing maintenance in the first place!

2. Tesla doesn't have a dealer network, but they do have a service center network: http://www.teslamotors.com/ser...

3. You want a loaner? You'll get a loaner. From http://www.teslamotors.com/ser...:

Tesla Valet Service
Tesla is putting in place a valet service, so that your car is seamlessly picked up and replaced with a loaner and then returned as soon as we are done. There is no additional charge for this.

Tesla Rangers Come to You
Tesla Rangers are service technicians who make house calls. For an additional fee, they can come to your home or office to perform most maintenance and warranty repairs.

4. "air conditioned seats, rear DVD, 360 degree camera surround support, automatic parking, adaptive cruise control, automatic crash braking". Ok, Teslas don't have any of that.

>You have to manage an inventory of expensive $20k+ parts that could be stolen,

All inaccessible and underground. They're also fairly useless to thieves; who would they sell a stolen Tesla Model S battery pack to?

The battery packs are heavy, unwieldy, and can't be resold to anyone. If you're a thief, there are much better targets.

>you have multiple sizes and model of battery,

All the loaner packs can be the same size and model.

> and different wear states. The batteries lose power constantly.

Since they're at the charging station, they can keep the batteries topped off. As they wear out, they'll be replaced. Tesla owns the loaner packs. The battery swap is actually a loan, not a true swap like propane. You have to go back to that station and get your original pack back.

>You have to manage liability, if you install a defective battery and it catches fire who pays.

Tesla, since they're both the manufacturer and the battery swapper.

>You have complicated machinery that you need to have many of to handle rushes that go unused at other times

It takes 93 seconds to swap batteries. http://www.teslamotors.com/bat...
They really only need one swapping machine on site for the foreseeable future, and if they get to the point where they need more swapping machines, then they're doing very very well.

Especially since swapping isn't going to be used day-to-day; you'll charge at home or work. Swapping is really only for long-distance trips.

>And you still need to have the same order of magnitude of power available to charge up the swapped out batteries as you would to just charge them in the car.

Of course. The advantage of battery swap is that you can run out your current battery, swap at the station, drive wherever you're going, come back, swap back for your now-recharged pack, and go home. 186 seconds during the trip, versus having to stop and charge for a few hours.

>A quick check at one service which lists such large amounts, you would be looking at almost $20k/year to keep a single offsite copy of tha

Amazon Glacier would be about $205/year to store 20 TB. A full restore would be like $2,000 though, unless you want to restore 1 GB/month. Still, that's a significant difference from $20k/year.

>But you must keep in mind (as I mentioned above) that to get monetary renumeration--rather than an injunction--you must have registered your work with the Copyright Office before the violation. And it must be registered--before or after the violation--to be able to make a claim.

I thought you were wrong, so I started looked up references. As it turns out, you're right.

> More data does cost more, it's simple.

No. A 600 MB/s pipe costs the same to operate whether you send 30 GB or 300 GB down it over a month.

Metering by the bit (instead of by bandwidth) is pure profit-taking.

>The idea of unmetered pricing is kind of insane.

Why? If an ISP's peak bandwidth is 600 MB/s, then they have to buy 600 MB/s of bandwidth. It doesn't matter how much you download during non-peak times; the pipe has to be sized for peak bandwidth.

Someone that uses 5 GB monthly, but expects 30 MB/s bandwidth during peak time, means the ISP needs 30 MB/s more peak bandwidth (so 630 MB/s total)
Someone that uses 300 GB monthly mostly during non-peak time, and only uses about 5 MB/s during peak time means the ISP only needs 5 MB/s more of bandwidth (so 605 MB/s total).

Metering by the bit is only vaguely related to costs. If you want to meter by bandwidth, that would make sense - but we already do that. You can have 10 MB/s for $x.xx, 20 MB/s for $y.yy, etc. Why should we *also* meter by the bit when we already meter by speed?

NZ's problem is likely that the trans-Pacific cables meter by the bit in order to increase their profit, and the local ISPs are just passing those costs on. In that case, the trans-Pacific cable operators shouldn't be metering by the bit, since it has no relation to their costs.

>RDP and VNC aren't much help if that server is waiting in the bios to tell you a SCSI disk is offline.

You can set up a gateway VM (or physical machine) on the same local network and RDP to that, then connect to your iLO/DRAC/IPMI/KVM. The bandwidth-intensive KVM will stay on the same network, and you can use a lower-bandwidth protocol like RDP to connect to the gateway machine.

Many places use this as a security measure - users from the VPN are only allowed to RDP/SSH to the gateway machine, then access internal systems from there. It makes it easy to firewall off systems from the outside.

>What should I do

There's a big difference between what you *should* do, and what you are *legally obligated* to do.

It's not clear from the FTC's website whether you are legally obligated to return the mistake.

>Yes it is, If you knew anything AT ALL about computers or electronics you would know that. Go look up how audio pathways work in a computer kid.

Two computers sitting in the same room, with both speakers and microphones, could easily communicate by emulating a 300 baud half-duplex modem, for example.

For even lower bit rates, use something like DTMF tones.

What is it that you find implausible about computers using sound to communicate, considering we've been doing it for decades?

> I do not know if that would be faster/better to do 'join' statement over multiple huge data tables compared to nested queries.

Yes. Someone who is writing SQL queries for a living should already know that, so asking him to rewrite it using JOIN would be useless unless it's an entry-level job, because he isn't going to get hired.

You're right in that asking people "why did you do it that way?" is a good way to find out if they understand what they are doing, but it should be asked open-ended like that at first, so that the candidate can demonstrate their knowledge. If you don't get a good answer, then ask "why didn't you use JOIN?".

>Also, why would GET & POST requests be involved in security?

GET parameters go in the URL and may be logged inadvertently or captured via Javascript. Search engines and browser pre-caching may trigger GET requests accidentally, so having a 'delete' action be a GET request, for example, would be bad.

More to the point, anyone in an internet security job should know this, because it's a building block to understanding more complex things. The candidate should understand the HTTP protocol thoroughly. If they don't know GET vs POST, they certainly don't know any advanced concepts that the job requires.

IRS mileage rate for 2013 is 56.5 cents per mile, so 500 miles would be $282.50.

Subtract the cost of gas (US new car average of 24.9 mpg, so 20.08 gallons @ $3.269 US average = $65.64) and you're left with $216.86 as the cost of operating a car for a 500 mile trip.

The IRS rates are high, you say. This calculator says between $0.15 - $0.30 per mile for wear and tear. Let's use the low figure, $0.15, which gives us 500 x $0.15 = $75.

Note that "wear and tear" includes depreciation, because the more miles you drive, the lower the car is worth. A 2002 car with 20,000 miles is worth more than the same car with 200,000 miles. It also includes tires, brakes, oil, timing belts, etc because the more you drive, the more often you have to change these things.

Many people don't count those as per-mile costs, and instead act like a new clutch or timing belt is a total surprise, instead of an expected result after so many miles of driving. However, they are valid per-mile costs, and if you budget appropriately, you likely won't ever have $1,000 surprise repairs - you'll just have expected repairs.

So if it costs the rental car company $75 and they charge you $50, how do they make money? Well, it doesn't cost *them* $75.. they have their own mechanics to do oil changes, brakes, tires, etc, and they get bulk rates on parts and fluids.

http://en.wikipedia.org/wiki/Double_negative#Slavic_languages

In Slavic languages other than Slavonic, multiple negatives are grammatically correct ways to express negation, and a single negative is often incorrect [...] For example, in Serbian, Niko nikada nigde nita nije uradio ("Nobody never did not do nothing nowhere") means "Nobody has ever done anything, anywhere", and Nisam tamo nikad ila ("Never I did not go there") means "I have never been there".

If it runs in a virtual machine, that would be enough to start. They can add device drivers later.

The other problems with the project are all too real though.
