Not what I'm talking about. I've had some ignorants attempt to convince me that touching the leads of a 12v car battery can lead to electrocution. The reason given was "it is current not voltage that kills and car batteries can push 1000 amps!".
It is all well and good if you don't know, but please don't try to inform others.
Hydrogen explosions are a real possibility on the other hand, but this is not to what I'm referring.
I took electrical engineering so I may have a touch of knowledge upon the subject.
A 9V battery is <40V and no one mentioned actually piercing the skin or actually removing your skin (what?) so I really don't think a 9V battery is a danger here.
Also, how are you going to ensure all the current from 2 electrodes placed ANYWHERE on the outside of the body go through your heart?
Anyways, if we were talking about higher voltages I might agree, but anyone touching themselves with a 9V battery ANYWHERE is probably a safe thing to do. Hell putting one on your tongue does not even generate enough current to make the muscle go into any kind of serious contraction, and that is about as close and low resistance as you can get.
Again, if you don't step the voltage up, or start driving nails into your skull/chest cavity and hook batteries up to them, i posit that 9V batteries can generally be considered safe, even to the uninformed.
3 replies and no pointers to the fact of how absurd it is to point out that you can kill yourself with a 9v battery?
Maybe with a massive amount of autotransformation to get it up to 20 volts and running it through your brain directly, but come on.
Like one of the misinformed people who are afraid to work on their cars 12v system because it can push "1000 amps OMG!". Just a clear misunderstanding of how electricity works.
Haha I go to Mexico every year. Mostly to relax. Spend a couple hours at the beach, some time in town, rest at the place just relaxing. Usually read a couple hrs in the morning and couple in the afternoon.
I try to fit the spear fishing, scuba diving, freediving, etc in, in between:)
I know slashdot tends to be a little Luddite-ish when it comes to ebooks/ereaders for some reason, but as an avid reader I couldn't be more happy.
When I go to Mexico on vacation, I usually go through a book every day or two. This means I would almost need an entire suitcase for books. With my Kindle, I just bring it! When I still manage to run out of books, the kindle has 3G damn near anywhere on earth for free, and I simply buy more. I have any book I want within seconds pretty much.
They are FAR more comfortable to read with than a real book as they are light and small, and don't have a fat side depending how far into the book you are. Nothing more annoying than starting a book and wanting to lay on your left side to read it. You also never have the problem of dry fingers having trouble getting a grip on the page, or accidentally grabbing 2 pages by accident.
Some people like to show off their book collections, or bring up that dropping a book and an ebook reader off a building only the book is more likely to survive, but for the massive massive convenience benefits, I suggest you store your ego, and take better care of your stuff. I'll worry about not being able to get new books (even though you can put text files on it over USB fine) when Amazon goes out of business.
This way books are cheaper, faster/easier to get, lighter, and easier to read. For me it is a no brainer.
While it does have creep, the creep really is very low, and with some jiggerpokery, can be reduced to be less than steel for much less weight, though more volume. Jiggerpokery being a bit of stretching it while heating it up. Dynex Dux is such a product, and they make standing rigging for sailboats. It ends up being much stronger than the steel you need since you size for creep, but with a bit of oversizing the creep is a good bit less than the stainless rigging it replaces.
Dyneema SK75 is also a good bit stronger than 1x19 aircraft cable in steel, and much stronger than stainless 1x19 of equal diameter. Obviously all of these options blow steel away in strength/weight. But even per diameter it is stronger.
The main drawback is of course the fact that they melt at low temperatures, similar to nylon ropes etc. In normal environmental conditions though all of the good stuff is retained.
Without the signal they simply use their quartz timing. If you think the clocks are simply displaying some received signal for time,that isn't how it works. They have a clue.
My Casio Pathfinder is always accurate to within a good deal less than a second, and the face is a solar panel so it keeps itself charged.
What site is there where I can instantly filter out all the crap, see the more relevant interesting/insightful posts on any nerdy news story that is posted?
Most sites have impossible un-threaded crappy comment systems,with crappy moderation etc.
I want to see 5-30 interesting comments on any given story,not 250 I have to sort through myself. I would also like there to be a higher percentage of people 'in the know' than the average population.
Is there another site just like slashdot basically,but with better story picking ? I'm not being sarcastic I'd actually like to know so I can read it.
What's stupid is the wrong stuff is being concentrated on.
If google maps loads in 3 or 4 seconds doesn't matter to me. What I want is for the whole browser not to hang its UI anytime one website is doing stuff. I hate opening tabs in the background and having the browser be unusable until they load.
Both apple laptops and my big fat gaming laptop have very easy to replace hard drives. My 2008 Macbook anyways had one panel with a clicky switch thing that let it go. You then had battery and hdd access easily.
My g73 has an access panel with 2 screws, then you can see ram, hdd, pcie, and some of the (replaceable) video card.
I don't read comics or graphic novels and have no desire to, but I found Watchmen fantastic. It is a bit of a slow movie in the sense that there is not action every five minutes, but it was a very watchable, very cool movie.
I wouldn't hesitate to recommend it as long as you don't need "Die Hard" or "The Expendables" level shoot em up action to enjoy a movie.
Put your games all in a folder on the second page.
If you're on another page and want to quickly get back to the first page just hit the home button again. Always brings you to the first page. (unless you are already on the first page, then it brings you to the search page).
Also, a free cydia tweak called '5 row dock' or something similar allows an extra icon in your bottom dock. Love it.
Not sure why exactly you would NOT include ebooks in best seller lists. They are books that are sold, money has been made, and the books have (in theory) been read.
I suppose you could make a separate list, but it sure seems like books are being sold, in one format or the other, those sales should be included in the counts for books sold.
Look at Music iTunes is far and away the largest retailer of music in terms of amount of music sold. I wouldn't say the iTunes bestselling list is worthless that's for sure.
Slashdot Mirror
Agreed on all points haha.
Just wanted to drive the point home that 9v batteries are not dangerous and no one should consider them so.
Remember the OP's point was that 9v on your skin can "KILL YOU". Absurd claim.
Not what I'm talking about. I've had some ignorants attempt to convince me that touching the leads of a 12v car battery can lead to electrocution. The reason given was "it is current not voltage that kills and car batteries can push 1000 amps!".

True, I did not consider that maybe you could shoot the battery out of a rail gun to kill someone!
Sorry 20kV, not 20V

This is a April fools thing I;m assuming but I bet some people would really benefit from this. Both eyes with same polarization I assume.
A lot of people bitch about 3D and how it gives them headaches, and the movie only being avail in 3D. This would solve that.
While I'm sure its a joke, thinkgeek should actually sell these.
Not like you're likely to ever see this, but the iPhone connector is a hell of a lot more than a USB connector.
Look at the pinout:
http://pinouts.ru/PortableDevices/ipod_pinout.shtml
Some notable mentions are Serial RxD and TxD, composite, svideo, AND component video, 3.3/5/12V, and others.
Other than only being used on apple, it is a really cool connector.
UHMWPE is used widely in bullet proof vests.

Atomic syncing clocks are fantastic.
Without the signal they simply use their quartz timing. If you think the clocks are simply displaying some received signal for time,that isn't how it works. They have a clue.

The organization is the important part, not the location of the tabs.
You would make millions happy if you found something like this for chrome. Its the main reason I haven't switched. That and the fake adblock.
Yes

And this is on a quad core i7, 8gb of ram.
Ya the energy densite is worse than 'not quite' by a long margin.
Just doing some napkin calcs here...
2.5V 50F (and you usually shouldn't put em right at 2.5 volts but anyways) is about 156 joules.
A NiMH battery is 1.2 volts 2.1WH is 9072 joules.
Not even in the same order of magnitude.
Both apple laptops and my big fat gaming laptop have very easy to replace hard drives. My 2008 Macbook anyways had one panel with a clicky switch thing that let it go. You then had battery and hdd access easily.
My g73 has an access panel with 2 screws, then you can see ram, hdd, pcie, and some of the (replaceable) video card.
Until the software 'engineer' is legally responsible for his code and problems resulting of his code, he isn't an engineer. He's just a programmer.

You want the US Govt to expend energy GIVING rights?
Not sure if you read the news but they don't do that sort of thing these days.
