THINGS YOU NEVER KNEW YOUR CELL PHONE COULD DO

El Prof. José Antonio  Giovannetti Román comparte con nosotros:

THINGS YOU NEVER KNEW YOUR CELL PHONE COULD DO.
There are a few things that can be done in times of grave emergencies. Your mobile phone can actually be a life saver or an emergency tool for survival.
Check out the things that you can do with it:

FIRST: Emergency
The Emergency Number worldwide for Mobile is 112. If you find yourself out of the coverage area of your mobile; network and there is an emergency, dial 112 and the mobile will search any existing network to establish the emergency number for you, and interestingly this number 112 can be dialed even if the keypad is locked.
Try it out.

SECOND: Have you locked your keys in the car?
Does your car have remote keyless entry? This may come in handy someday.  Good reason to own a cell phone: If you lock your keys in the car and the spare keys are at home, call someone at home on their cell phone from your cell phone. Hold your cell phone about a foot from your car door and have the person at your home press the unlock button, holding it near the mobile phone on their end. Your car will unlock. Saves someone from having to drive your keys to you. Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other "remote" for your car, you can unlock the doors (or the trunk).
Editor's Note: It works fine! We tried it out and it unlocked our car over a cell phone!"

THIRD: Hidden Battery Power
Imagine your cell battery is very low. To activate, press the keys *3370# Your cell will restart with this reserve and the instrument will show a 50% increase in battery. This reserve will get charged when you charge your cell next time.

FOURTH: How to disable a STOLEN mobile phone?
To check your Mobile phone's serial number, key in the following digits on your phone: * # 0 6 # . A 15 digit code will appear on the screen. This number is unique to your handset. Write it down and keep it somewhere safe. When your phone get stolen, you can phone your service provider and give them this code. They will then be able to block your handset so even if the thief changes the SIM card, your phone will be totally useless. You probably won't get your phone back, but at least you know that whoever stole it can't use/sell it either. If everybody does this, there would be no point in people stealing mobile phones.

And Finally....

FIFTH: Free 411
Cell phone companies are charging us $1.00 to $1.75 or more for 411 information calls when they don't have to.  Most of us do not carry a telephone directory in our vehicle, which makes this situation even more of a problem.  When you need to use the 411 information option, simply dial: (800) FREE 411, or (800) 373-3411 without incurring any charge at all. Program this into your cell phone now.
This is the kind of information people don't mind receiving, so pass it on to your family and friends

$100 laptops coming soon!

The Universal Learning Machine
By Ken Messersmith

The Universal Learning MachineWe are speeding toward the day when students will bring an electronic learning device with them to school. The MIT $100 laptops are about to ship, and I believe it is inevitable that similar devices will soon be available for American students. This future brings up the question of what would happen if teachers were allowed to design these things. Let me start with a list of features and then see what the Spiral Notebook community thinks.

The device should be small but not too small. It is important that the display be large enough to clearly show the contents of a Web page. Something between a portable game player and a laptop in size should work. A good bright color display will be essential.

The memory, for durability and to conserve power, should be based on flash memory. Some type of wireless battery-charging system would be ideal. Solar power would be best, but we might have to settle for one of those wireless pads for charging the battery during lunch or recess. Wireless capability must be included, and a couple USB ports would add flexibility.

If we could make it durable enough, I would like to see a touch screen, which eliminates the necessity of using a separate mouse. The touch screen might be able to double as a keyboard, or we could include a fold-away keyboard that could be stowed out of the way when we are using the touch screen.

What about software? Necessities would include a browser, a word processor, and photo-editing, video-editing, and multimedia-presentation tools. I would also include a spreadsheet with graphing capabilities for math and some type of graphic-organizer building tool for abstracting and note taking. Some of these tools might be Web based, making it unnecessary to maintain them on the machine.

This device needs to be in the $100-$300 range to make it affordable for families to buy or for school districts to provide. What have I missed, or what have I included that should be modified or eliminated? Please let me know.
