I thought this was interesting, now your beating on your laptop does something useful
QUOTE
For the first time, you can hit your computer and get a meaningful response! Using Linux and the Hard Drive Active Protection System (HDAPS) kernel drivers, you can access the embedded accelerometers on Lenovo (formerly IBM®) ThinkPads, then process the accelerometer data to read specific sequences of "knocking" events -- literally rapping on the laptop case with your knuckles -- and run commands based on those knocks. Double tap to lock the screen, and knock in your secret code to unlock. Tap the display lid once to move your mp3 player to the next track. The possibilities are endless.
IBM first intoduced this technology in 2003, originally to protect hard drives if the laptop was dropped. But, thanks to some clever enterprise hackers at IBM, Linux has been modified to take advantage of accelerometers located on ThinkPads. On-screen display orientation, desktop switching, even game control and real-time 3D models of the tilt of the laptop are now available. This time they added a new twist -- knock codes -- and a simple program to run commands when specific knock codes are detected.
lol How ever interesting that sounds I think I'll pass. So many people can hear your little knock for your password and I think your the screen would get damaged by this because of overusage. I mean sure it's probably durable but think about it. You enter your password twice a day, five days a week for two years. I don't think thatit would really be able to withstand all that. I think I'll stick with what I have.
Nice idea, but I can just imagine people sitting in a library or something, all hitting eachother's laptops. You're trying to write an essay and suddenly some wiseguy decides you're gonna start blaring out Pink Floyd, while playing the nearest available DVD and then locks the computer with a special passknock known only to them... It still seems quite cool though.
Very interesting but depending on how hard you have to hit the laptop for it to pick up a response, the knocks still could be detromental to the rest of the computer. Just because you wont damage the harddrive you could mess up your video card, rom, or even the processor since they are positioned so close to each other inside the case. Good idea but i dont think it is going to be very useful.
As I was reading I thought it was a joke. I cant believe it really, sounds kind of dumb to tap on the notebook. I would rather stick to the keyboard, I wouldnt want the knock device failing and keeping me out of my system.
Wow. People never actually realized that, like all OS features that are non-Mac, Linux programmers had copied this idea from Apple and their latest MacBook Pro notebook. It contains a sudden motion sensor that detects sudden movement and turns off the harddrive. Programmers had decided to use this so that whenever you "smack" your MacBook, it will change desktops. (Link - http://www.gizmodo.com/gadgets/laptops/sma...pro-176255.php). Also, there is something known as the MacBook Lightsabre, where this motion sensor can equally be used to create appropriate lightsabre sounds, as if you were swinging around a lightsabre. (Link - http://gizmodo.com/gadgets/laptops/matt-ha...deo-175802.php).

Sounds pretty cool to me cool.gif
Sounds pretty dumb,but its original

I think that if we hit the computer, it should have sensors to sense that the person using the computer is pissed, and it should fix the problems NOW...
If i got a laptop computer i dont see me using it. If you hit your laptop you would either have to hit the sides (and hopefully not pop open the cd/dvd slot) or turn it over and hit it.
If you hit the key board who knows what would happen...
As I was reading I thought it was a joke. I cant believe it really, sounds kind of dumb to tap on the notebook. I would rather stick to the keyboard, I wouldnt want the knock device failing and keeping me out of my system.
I agree with that, what ever happens if the "Knock" system fails? Who can you ever get back into your system? Does it have a backup login so that if you fail "3 times" for example a password enter dialog box appears so that you may type your password in. then again if the "Knock" system fails how might you "Fail" Password Guesses? It should then have a Keyboard shortcut to open that Password entry dialog box, right?
This seems like it would need a really strong computer, and when I hit my laptop, it's usually because it just lagged me out of a game, so I'm not sure I'd actually use it for the functions.
a good idea but cannot be that good in reality. too many problems i can see with this one and with just that function, i know the price with double because of the add ons

Hi there guys, I just bought a brand new Dell Inspiron laptop for $729.99. It has a
processing speed of 2.0ghz, 3GB RAM, and a 250gb hard drive. I'm really satisfied, especially
with the wireless internet and the fact that I can carry my computer around with me, allowing you to
use your computer in comfortable spots -- outside in the shade, on the train, or even in your bed
where I'm using it write now as I type. If you didn't already guess, this is my first
laptop. But I do have some issues. Does anyone happen to know an easy way to transfer some ....
well in just a little over a year i'll be going to college and i was wondering what would be a

would turne into typed text. but one thing i want to make sure is that if i do get one, would i
still be able to get all the different softwares i like and if i could play games on it? what do

I was hoping some linux tech heads here could give me some pointers about installing linux onto a
laptop I have which has no cd drive. To make things worse it does not even boot from usb. I had
installed XP on it with an unattended install using the /makelocalsource switch which copies files
to the local hdd then finishes setup from there after reboot. Is there an easy switch function to
install any linux distro once you have the files on your hdd? (I have a mapped network drive to my
laptop and sharing from my desktop so i can access my files. I just don't know if....

Well, my mom is buying me a graduation laptop and my budget is about $2500. This is the laptop
I've found to be the biggest bang for the buck, but as I'm not great at this stuff I figured
I'd ask for help. The speed and memory of the laptop is pretty much set at the speed it's
at (2.5GB L2 6MB, 4 GB RAM, 640GB HDD). Also I don't want to lose bluetooth either. So, if you
have any comments or suggestions, please let me know, if you find better offers for the same machine
I'd be happy to know about them as well. Thank you for your time!....
As some of you may know the macworld expo was today, and as even less of you know I

posted up the way that I found to do it, so here I go. Supplies: Laptop connected to internet Xbox

You may think that this is very wierd but I believe that we have another sense that even we do not

when you feel like someone is watching you just to turn arpund and see that someone is actually
there? It sounds crazy but I do believe that this is true and scientist need to do some research.

This is the laptop created by Nicholas Negroponte. He is the co-founder of the MIT Media library.
Well basically he had this idea of allowing children in poverty stricken countries or developing
countries to have a laptop that cost only $100 USD. Its really interesting how they were able
to produce such a laptop and at a low cost too. The laptops are designed to educate and develop
their intellect. QUOTE O creates its own mesh network out of the box. Each machine is a
full-time wireless router. Children in the most remote regions of the globe—as well ....
For those of you (er, any -if that's the case) who've heard about the Synthesis Kernel in
Massalin's PhD thesis, has anyone tried to make an x86 version? And to everyone who doesn't
know what I'm talking about: The Synthesis Kernel was a self-modifying os kernel written in 68k
assembly that emulated unix. (a Sun's version I think, I can't remember) Seems that the
emulation went faster than the real thing, maybe the only time that ever happened. /laugh.gif"

My aunt gave me her old laptop, and I want to reinstall Windows on it. For sarters, the DVD-ROM
drive is not first in the boot order. So I need to open the BIOS Setup program to change it. I tried
pressing about half a dozen key combos, and couldn't get it to run. I called Dell, and they gave
me some garbage, saying that I would have to pay to get help. So I come here, to ask you, how does
one open the BIOS Setup program on a Dell Inspiron 8000 laptop?....

I have a personal laptop for my own use, which I left at home for about 6 hours. The problem was
that I forgot to put on the adapter, so that the battery won't run out. And there I was, when I
came back home, the laptop's battery was out. I immediately connected the charger but the
"Charging Light" was not going on. I tried to turn on the laptop after a while, but it was not
working. I am not sure why my laptop is not recharging. Does anyone know how to fix this problem?
