Comment Re:Mask this by violating TCP rules? (Score 4, Interesting) 81

What you're talking about is a forward proxy. Forward proxy servers do this (and will even proxy SSL traffic).

In the whitepaper, they're actually talking about making a new protocol that measures the one way distance time and compares it to their database of network speeds and distances to determine your location. Their solution is an application-level solution, which depends upon a Forward Proxy to know about the protocol and spoof it correctly.

The problem with their solution is that network speeds are fluid and a computer with a problem (e.g. a local neighborhood node or a legitimately slow client that is delaying all traffic 20-30ms) can make their estimates wildly inaccurate. Even today, Cogent to Level 3 has a 197ms ping in LA. In the paper, they used average speeds for various known networks. This can be mitigated somewhat by measuring client traffic and only counting outliers (e.g. all traffic from a certain area being delayed the same, except for our rogue client) but it still doesn't mitigate the local computer problem.

A second problem with their solution is that it only measures distance - a server in Miami, Florida accepting data from a client in Seattle, Washington is 2732 mi and the same distance (roughly) as Lima, Peru. This means that a client in Lima should pretend to be from Seattle when they connect to their combo VPN/Forward Proxy in Miami. Satellite customers are will almost always have extremely high latency because of the round trip between Earth and the Satellite, even if they're legitimately in the correct area.

In addition, they were only able to make this accurate to about 400km, which means if you have a nearby beneficial country within that range, you can use a VPN in that country and they still won't know.

That's why the states have the ability to raise the minimum wage in their state above the federal minimum wage to better reflect costs of living, but they are unable to make it lower. For example, California is $10/hour and New York is $9/hour while the federal minimum wage is $7.25/hour.

In this case, a more accurate example would be you doing a search for transaction data using the bank's own search feature and finding transactions from your neighbor mixed in with your own data. The guy wasn't hacking. It was openly displayed and mixed with their own data. The first time it happened, they reported it immediately and the vendor said they would fix the issue. This time, he did some searches to find out what was going on and got locked out and accused of looking at his neighbor's transaction data.

The sad part is that the X1 boxes are an upgrade from the old boxes that didn't even work properly on 1080p televisions.

Good luck getting on demand programming to work properly on those. Most of the time they would crap out with some unknown error that Comcast couldn't fix over the phone.

Comment Re:Does it matter? (Score 2) 668

Have you gone to the grocery store or local quick stop to pick up some over the counter medicine? That homeopathic crap is sitting next to the real drugs in the same exact section, both of which cost the same (or the homeopathic crap costs more!) and both of which declare in big letters that they cure similar symptoms.

You have to read the box to find out which one has real drugs in it that have been scientifically proven to have actual effectiveness at the proper dosages for the symptoms that you have or you'll very easily pick up the homeopathic crap by mistake.

Comment Re:cordless phone charger (Score 1) 75

Yeah, my mouse had similar tech. You dropped it into a cradle and it would charge...

Unfortunately, it had the nasty problem of the contacts corroding or wearing off, preventing it from charging. Given that it was corroding in a mostly temperature and humidity controlled environment, I won't give good odds to these things lasting in a hot and muggy car.

As an ancillary comment to this, you'll sometimes run into this issue with cheap or older hardware as the components begin to heat up. Turning it off after a little while would allow it to cool down or putting the modem in a location where there's more airflow would keep it cooler.

In particular with Centurylink, their cable boxes will freeze and reset if they get too hot, and their power tolerance is really low - to the point where we had to plug it directly into the wall because the voltage / resistance difference from a normal power strip would cause it to lock up.

Yes, because they will realize that being a mouthpiece for a propaganda machine and catering to a small core of their demographic is alienating to a large segment of the population.

Some day, those people that are making the decision to pander to their base will be replaced, and hopefully there will be a culture shift towards moderate. At that point, we will stop thinking of that as clever, because it will no longer be true.

Comment Re:Still a niche company (Score 2) 111

I live in a metropolitan area of a red state on the east coast, and not only have I seen Teslas in person, but I know people (friend of a friend) that have them. It helps that there's a supercharger at a nearby mall that I almost always see a Tesla parked at, but I've seen them parked around town, too.

Your anecdotal evidence is just as good as my anecdotal evidence, and neither one is indicative of the actual popularity, supply or demand of the car.

Comment Re:Sound waves as quantum particles? (Score 1) 66

Well, we already know that individual atoms have sound so they're probably talking about sound in a way that the layman wouldn't consider is sound. At this level, they're probably talking about the vibration or movement of energy within the rubidium Bose-Einstein condensate traveling at the speed of sound and generated from the Hawking Radiation at the Sound Event Horizon.

I think his point is that an ASCII log is human readable with any text editor without needing an interpreter program.

Binary logs tend to be full of garbage to the average human and transferring the log file and/or running the log program aren't always feasible when you're in recovery mode.

Given that systemd is the boot up daemon for the entire system, being able to read the logs when the system won't boot properly is incredibly important.

Comment Re:Franchise laws = Racket laws (Score 3, Insightful) 157

If you only read the laws themselves, you wouldn't think that. In theory, the laws are there to give you better service through a dealership because the evil large corporation gives you poor service at a steep price. They're there to prevent a monopoly on service so that you're not required to go to a Ford Garage so that a Ford Mechanic can fix your car with Ford Parts and price gouge the hell out of you.

In practice, they still do it and with the kickbacks and other ties to the parent company, they might as well be the same thing. The dealer ends up being the middle man that takes his cut and raises the price by thousands of dollars. The laws have effectively enshrined the dealership business model and Tesla threatens that.
