The Lorentz force is f=q[E + (v x B)]. That is, if you've only got a magnetic field you need some v in order to get some f. The charge has to be moving in relation to the field. In the paper they use a form of the equation with current instead of a moving charge, but it's the same thing.
They DO test in a static field, and see an effect, which suggests that there is a continuous current in the semicircular canals (which seems weird). A changing field (due to head movement or gradients) would certainly increase the effect though, and might well be much stronger, particularly in the case of quickly changing gradients.
STATIC magnetic fields don't have much effect on tissue. Changing magnetic fields have an effect on anything that conducts electricity, living tissue included. The effects are well known and the rate at which the magnetic fields in an MRI scanner can change is regulated to avoid causing unwanted nerve stimulation.
You might want to be a little more careful before calling a trained professional narrow-minded or pseudo-educated. Unfortunately your post is the one that comes across that way.
I think the worry is that the motherboard manufacturers will get onboard the Microsoft train. If the paranoia pans out then you might have a little difficulty doing that.
"but we are talking about the one in a million type person/personality types. Just like there is little chance any kid you went to school with would ever be a NBA/NFL star or Hollywood A-lister (or even B and C) their chance at this level is equally small."
Hm... maybe that's the problem. HP (and other companies) should stop hiring one in a million, self-important sociopaths with overly inflated egos and try some normal, competent people.
Silly, if you imposed requirements like that you wouldn't be able to attract the best talent to be CEO of your company. You might get some schmuck who actually made your business profitable!
Most smokers seem to have to be reminded that they're not allowed to smoke by frequent, visible, almost obnoxious signs. Even then sometimes they forget....
That video was pretty, but disappointing. Basically, except for full colour e-ink and edge to edge displays, Microsoft thinks that in eight years things are going to be the same as they are today except that we'll all have bought a lot more Microsoft devices.
It's definitely an oversight, but should be fixed pretty quickly. The one line fix at the end of the article (restricting permissions on dscl) seems reasonable.
So? People do all kinds of non-cost effective things, particularly where their kids are concerned. If the daycare finds that having these things makes their customers happy and doesn't hurt the kids, what do you care?
If you have a music teacher who is going to be teaching a new unit on an instrument she doesn't play, she takes lessons or attends a workshop. You don't make the math, phys ed and social studies teachers go too.
Here in Canada we call it professional development and there are several paid days every year for all teachers to do it in subjects relevant to what they teach.
No, it's a stupid idea, no matter who thought of it. Look, I grew up in Texas and Florida. one of my English teachers was dumb as a post, so much so that she just told blonde jokes instead of teaching. I survived. So, I imagine, did everyone else. I even survived learning math from one teacher who couldn't add fractions, nor answer any questions about geometry.
It's just racism, plain and simple.
Incompetence is incompetence. If, as a teacher, something about you makes it difficult to learn, then you are a poor teacher. People who are poor at their jobs should either work to improve their performance or find something they are good at.
You were listening to an accent that's not particularly foreign to most English speakers, and you were presumably in contact with them fairly constantly.
I had several professors (who I saw for a few hours a week) with very strong accents far more foreign to an English speaker than Australian (which I usually have no problem understanding). Figuring out what they were saying in a large lecture hall was not simple.
If your job is communicating to an English speaking class it's not bigotry asking that you be able to do it effectively. It's certainly not bigotry if the school is offering to pay for a class to improve the accent.
Browser passwords on a Mac are in the system keychain, which you have to give the password for. If you're using Mail.app, which I assume you mean by "iMail," it's the same deal. Passwords are stored in the system keychain and are accessible by Mail.app but not by other apps, without the password. I guess it could probably scrape any locally stored e-mail though.
Anyway, I really don't care what happens to someone dumb enough to click on a fake PDF that's sent to them and then click yes, it's okay to run this untrusted program that just got downloaded from the net. So long as their computer isn't sending me spam.
Yup. I've got a little iPhone app that can scrape the usage information from my providers' site and give me how much I've used, when the rollover date is, how much data per day I've got left and whether I'm on pace to come in under the cap or over.
Nobody reuses paper. They recycle it. And that's a whole other ballgame. Wikipedia says recycling paper actually uses MORE fossil fuels than producing new pulp because new pulp mills get energy mostly from burning wood scraps while recycling plants usually use electricity, which tends to be produced from fossil fuels, particularly in the urban areas where you want your recycling plant.
No, if you don't use paper less trees get planted. Paper is a major consumer of forestry products and most of it in the first world comes from managed forests - they're harvested then replanted, just like farms. If they're not harvested, they don't get replanted.
Stop recycling paper. I love suggesting it because people snap to the judgement that not recycling MUST be a bad thing. To be fair, I'm not positive not recycling would be a net carbon sequestration scheme, but it's certainly possible.
In the first world forestry companies usually plant MORE trees than they harvest, so at least 100% of the harvested trees get replaced. The paper products are basically sheets of sequestered carbon. Bury them deep enough and they'll stay that way, until they get turned into coal.
Kinda kills the fun when your DDOS/spam relay etc. gets itself zapped every time the user restarts the computer.
Mac users tend not to restart their computers very often, but the ones who randomly click on executables sent to them by e-mail are probably the few who do.
Oh, and on a Mac your passwords are stored in the system keychain, which is encrypted and yes, does require your password to access.
Just build yourself a cat tracker. They're a famous DIY electronics project. As a bonus, when your niece isn't around you can track your cat. It really is interesting to see where they go (just not in real time).

Unless you enjoy etching PCBs, that is.

There still isn't' one today.
There are a few vulnerabilities, but no malware that exploits them. Yet.
SHA-512, according to the article.

Okay, the MAJORITY of paper reuse/recycling is recycling. Happy?

Come on. Don't tell them the little clip is a GPS. And it's not constant anyway.
I suppose ordinary supervison conditions them to believe that constant surveillance by authority figures is normal.
Presumably they're not allowed to take their stylish reflective orange vests home with them.
So the GPS kills two birds with one stone. The kids are easy to find if you do lose one and it's a lot easier to take them outside to play.
A little GPS tag isn't a climate of fear either. It's not an antikidnapping measure or anything silly like that.
No. They're in jail. They're not allowed to leave.
