Comment Re:PSA: on "fingerprint scanners" (Score 1) 430

Your typical phone stylus causes a change in capacitance when touched to a phone's screen, which is good enough for it to register that there's something touching it and trigger an event.

The sensors in the fingerprint scanner on a phone are much more accurate than the rest of the screen, to the degree that it's easy to tell the difference between the changes in capacitance caused by rubber vs. human skin, and also it can detect the gaps between ridges on your fingers, which a stylus doesn't have.

Do people have trouble fingerprint-unlocking their phones?

The false negative rate is actually quite high. When calibrating a phone's fingerprint scanner, it'll typically have you place your finger on the scanner several times at several different angles so that it can see what your finger's response is like in a variety of positions; even with all of those measurements, it's not uncommon for it to take two or three attempts for your finger to be accepted if you don't put your finger down in just the right place at the right angle.

Comment PSA: on "fingerprint scanners" (Score 2) 430

I see a lot of people here who are repeating the "why would you use fingerprints for authentication when your fingerprints can just be lifted off of any nearby surface?!" line, which is ignorant of how fingerprint scanners in modern cell phones actually work. Read up on it a bit:

The short version is that no, the police will not be able to fool your phone's fingerprint scanner by using a print collected off of something else you've touched. Modern scanners do not record visual images of your fingerprint and match against that; they measure either changes in capacitance associated with the ridges of your finger touching the phone or your finger's response to an ultrasonic pulse. Both forms are incredible hard to fool with a prosthetic (and probably won't even work if your finger has been severed, although I don't know if anybody's tested that).

If somebody in your back seat reaches forward, grabs the steering wheel, and forces you to get into an accident, who is liable? You, because you didn't stop them? The car maker, because they didn't prevent anybody but the driver from grabbing the steering wheel?

The hacker is obviously the liable party.

Aha, I figured it out. I've been trying to figure out what kind of point you were even trying to make, as it seems like you've been trying to argue that you're not a hypocrite if you're doing it for moral reasons, and you've been doing so by trying to trick me into saying the magical words "free speech" so that you can trot out the typical censorship-apologist line about how it's only illegal if the government does it, and then you can try to convince everybody that because it's not illegal for private entities to do it, it must be moral...

But I didn't actually say "free speech," nor did I imply what the companies in question are doing was illegal at all, and you're going off on a tanget and putting lots of words into my mouth. Stop it.

Let me try to clear up the cognitive dissonance you're going through right now. You've always been told that, as an American, free speech is paramount. On the other hand, you believe that when somebody says something you think is immoral, it's your job to stop them. You don't like being labeled a hypocrite; you internally associate that with being bad because you've been raised to believe that suppressing speech is bad, and you don't want to acknowledge that's what you're doing. Internally you realize that it's true, so rather than acknowledge the dissonance you're doing your best to convince everybody that it's not hypocrisy if you're doing it for moral reasons.

What the companies in question (and you) are doing is perfectly legal, and possibly even morally correct, but I haven't commented on that at all. It's still hypocrisy. Stop trying to weasel out of it.

If you have evidence that somebody is "purposefully spamming deliberate lies," that's libel and you should go through the appropriate legal channels. The purpose of a business is to make money, not to enforce morality. But you're not a hypocrite unless you claim to support those peoples' speech at the same time that you're taking action against it.

Also apparently Luckey's girlfriend has been harassed off of Twitter, and you'll get banned from NeoGaf if you suggest that maybe she shouldn't be harassed. Stay classy, internet.

GPS with full spectra is accurate to 0.1 meters

Are you talking about RTK / CPGPS? I'd love it if you could show me a consumer cell phone that's capable of that. Every cell phone I've ever seen is lucky to get 3 m accuracy when it's outside and quickly degrades to >10 m indoors.

As to deets on in-building, there are tons of scientific papers on this, grandpa.

But you can't actually produce any at the moment, of course.

We can locate you within a meter based on cell tower logs, actually

Would you care to share the whitepaper describing how to get sub-meter accuracy from cell tower triangulation? As somebody who has actually done radio direction finding for a living I was under the impression that cell tower triangulation was considerably less accurate than GPS -- usually to within about 3/4 of a square mile.

If it's so accurate, why do cell phones even bother using GPS, which is accurate to about 3 meters if you're lucky?

NMS promised a lot of things you cannot possibly test in the first few hours of grind and surprise these things are missing.

That's true, but five hours is still enough time to tell whether you're having fun or not. If you force yourself to push through something you're not enjoying for five hours just because you're hoping it'll get good, you're a sucker.

Well, at least you're willing to admit that you're acting entitled.

Even if a game has enough content to last a thousand hours, you should be able to tell whether you're enjoying it or not within the first few. If you play a game for two hours and you want your money back, that's totally reasonable. Heck, I'd even say five; there are some games that take a while to get to the meat of them. If you spend 50 playing a game you don't like, you're a moron and should consider the $60 you spent to be the cost of the lesson you just learned.

I'm not a gamer, but the thing that interests me that no one is talking about is the fact that they apparently know how long you have played the game. Why is anyone OK with that?

Because that's very, very old news. Steam has been doing that for about twelve years now. Every game on Steam has Steam's DRM integrated into it, which makes it trivial for them to track which games you're playing, how long you've played them, who you've played them with, and so on. You can launch Steam in offline mode, but it'll sync up your stats next time you go online, which you'll have to do if you want to buy more games or play multiplayer, anyway.

As a non-gamer you might see it as a "grotesque invasion of privacy," but to most gamers it's not just fine, it's a welcome feature. They like being able to show their friends what they're playing, compare stats, and so on, and Steam facilitates that.

So, it doesn't even warrant a mention because most people like it and the ones who don't have still been used to it for over a decade now.
