Hell isn't all that far from Detroit and I have been hearing they have quite a problem with, like, 2 meters of snow this year. So yeah. Hell froze over.
I see 3 possible sources for your problem: a. the MP3 player is badly designed. There should be sufficient capacitance to smooth the power level out to within a few percent of standard even at full read or write. Alternatively the audio traces could be routed too close to the data lines or the designer for the DAC may have had a bad day. This means that the MP3 player was cheap enough that the designers weren't allowed the time to test their design properly. b. Your ears are magnificent. That would cause you to hear sounds that the designers didn't feel were relevant. c. Nocebo effect. You feel there might be a sound so there is a sound. These sounds can be really annoying.
Of course it could be something else that I have missed but these are the parts I would test.
I'd love to hook your MP3 player's audio out to an oscilloscope and see what it could be.
You should have demanded your money back. You let the bastards get away with it and not only did they not fix it, they cripled the CPU freq scaling as a "fix".
Not quite. Samsung has quite sufficient access to cc data. They probably wouldn't abuse mine. No certainty, mind you, but a chance. If a hacker would get access to it the chance it would be abused would increase. That is why it is better to send it to as few people as possible.
Added to that the data in the story is different. It's about data that can be copied losslessly. If I were to be filmed dancing naked to YMCA I would prefer to have it stolen by as little people as possible. My strong preference is 0.
That would be totally impossible by the way because I totally don't do that every Thursday night. *shifty eyes*.
The sites that work with Ideal (my preference) send me to my bank's site to sign the transaction with a simple challenge-response OTP verification involving a separate device where I can insert my card and need to use my PIN to get to the challenge-response part. Safe, but not too cumbersome. I love it.
Kill the antenna, not the chip. The chip is used in contact based payment too. The antenna is usually located on the edge of the card. Get a hole punch to punch a hole in the middle of each edge of the card. Now RFID is dead but chip payment is alive. Test it with a contactless payment point if you come across one. It should not detect anything.
If your cc is used for contactless while you have emails or papers stating that contactless should be disabled then there is no way you are liable. As for how to prove it, well I can't help you there.
Thes guys are quite crafty: The official reason we switched to pin and chip As you can see in the images there are some ways. 1. A sensing and transmitting layer over the keypad. 2. A camera drilled into the ATM, aimed at the keypad. 3. Good old fashioned looking over a shoulder. (could be called lack of reasonable protection).
I think we agree but we are both trying to be as clear as possible. I just posted the chemical toxicity of uranium just because the common thought (in the rest of the world) is that uranium is dangerous because it's radioactive. Once you get to know radioactivity a bit better most people start to think it's cute and cuddly because it isn't all that radioactive. This is the phase many/. posters seem to be in. Next thing some find out is that uranium is toxic, as a chemical. I was trying to guide the group mind in that direction. Multiple levels of insight.
Veterans of both gulf wars suffering 'Gulf War Syndrome' are, in reality, suffering from inhaling radioisotopes, i.e. radiation poisoning. A 1998 report by the U.S. Agency for Toxic Substances confirms that inhaling DU causes symptoms identical to those claimed by many sick vets with Gulf War Syndrome. So they may not be casualties of the war in Iraq, but they suffer for the rest of their lives when they get home due to their own government's policy to deploy du weapons, which is a war crime under UN conventions. That's the effect on the soldiers just for firing the weapons.
Depleted uranium is carcinogenic, causes brain damage and reproductive organ failure among other nasty things. Not because of it's radiation but because it's a really nasty toxin, and the reaction products aren't nice either.
Chemical problems, not radioactive.
For a comparison, about 50 kilograms of uranium were used to bomb Japan and over one thousand tons of DU in Iraq. This is how nuclear waste is being used and what a 'dirty' nuclear war looks like. I don't think the claim that there is no grounding in science has a basis however the effects are plain to see. I agree that it is political theater, based on concealing and deceiving people into what is being done in their name.
The radioactivity of nuclear bombs is different from normal decay. The type of radioactivity in nukes is not relevant if you're not busy getting the mass to critical. The DU in Iraq is spread over a large surface area. It's nowhere near going critical. Ergo the radiation source of a nuclear bomb is not relevant to the discussion. It's like we are talking about being killed by licking the contacts of a bare wire and you think of lightning strikes. Different source, different scale and different just-about-everything.
Having said all that, the US are not exactly playing nice with their DU projectiles. It could plausibly be called chemical warfare and just about as illegal as the use of mustard gas. However, who is going to arrest the US president for it? Do you have any idea what kind of international problems that might cause? The world is a playground and the US is the strongest kid. If you play along with what the US wants there is no problem, but nobody is going to attack them except the joker.
Nope. A cell phone makes a very weak field. A railgun makes a very strong field. It needs the strong field to work.
A railgun makes an EMP every time it launces. The first two sentences of the wikipedia article:
An electromagnetic pulse (EMP), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse may occur in the form of a radiated, electric or magnetic field or conducted electrical current depending on the source, and may be natural or man-made.
(emphasis mine) This is exactly what a railgun does (if unshielded).
In that case the EMP is most likely not the biggest problem. The biggest problem, heat, will destroy conventional weapons just as completely as railguns. Or maybe even more, since the explosives in the conventional shells might react violently to the energy pumped into them.
A rail gun works by creating a massive magnetic field with a huge current. That same current induces massive Lorenz forces. Those Lorenz forces accelerate the projectile. To accelerate effectively the current ramp needs to be steep.
That combination of a massive magnetic field with steep ramps is an ElectroMagnetic Pulse, or EMP. The railguns the Navy develops are big and thus they have big electromagnetic pulses. Any not EMP hardened electronics near them just die.

With 8 a decent controller can keep it up in the air (at degraded wind resistance and maneuverability) when 3 are lost.
I'd mod you down because that is not a "naysayer" thing. It is a "yes we can" thing.
The parent was about naysayers

You are not mistaken.
However, this virus apparently and logically also needs root access. Unknown sources does not grant it that. Rooting your phone does.
It needs both to work.
I have friends on the other side of the planet. I can be loud if I want to but I doubt I could shout hard enough for them to hear me.
No it doesn't. It's better to send my data only to Samsung and not to random hackers then it is to do both.
Not by much, but it is better.
I should go and cyanogen my S4 Active.

And if you, logically, don't trust the manufacturer's tests there are some others who have pushed over a terabyte to SSDs:

I like to limit the amount of people I send my private data to. Preferably to 0, but to add random hackers to it is not the right way to go.
Nope, but "Give me your lunch money or I'll stab you with this chisel I stole in shop" does.

But beer coasters are no telescopes.
Yeah. The problem there might be that I don't always agree with the US courts.
There is a major difference, although it may not matter in US courts.
I am not in the US by the way.
