Wiki Leaks and Computer Hacking.

NBC says  the Wiki Leak things reveals a major hacking tool used by CIA.

But now the attention is about who told. The government reaction is al about who told and not about the harm that was done. Here is a quore from the NBC news website:

A MAJOR mole hunt is now underway as the Federal Bureau of Investigation tries to find out how anti-secrecy site WikiLeaks got its hands on alleged CIA hacking tools.

Here’s the link for the Full Story y from NBC.

Recalibrate Your Laptop Battery

The battery meter has to be adjusted to keep it accurate.

No, it will not hurt anything if you ignore it. But don’t you want to know how much life is in your battery? Here is the general method.

First, charge the battery fully and then a little more. That way you know it is at 100 per cent full.Next, make a note of the time. Unplug the charger and use your laptop and use it the way you normally do. Do not turn it odd. Just continue to run it on battery until it shuts down by itself.  Note how long it took.

With this information you can now calibrate the charge meter of your laptop. Look in your user guide to see how to doit.

For Apple iPad click here. Apple Battery Adjust.

For HP subnotebook here. HP Battery Meter Fix.

For Dell use this link. Dell notebook Battery calibrate.

Also, there are some video son You Tube about battery calibration.  Take a look at some of the videos and learn how.

You can skip the ads and look for a video that best describes your mobile device. It is not hard. Take a look.

 

 

 

 

 

How to visualize what yu can not see.

Impossible? Almost. But some man have done just that. Think about silicon  CPU in your computer.

About 30 years ago Intel introduced the 036 CPU for desktop computers and workstations. That tiny slice of silicon had some features as small as one micro meter in width. Can you imagine how small one micro meter is?  A human hair is about a 50 micro melter in thickness. Think of a copper wire 50 times smaller.

But now Intel and others make silicon chips with traces as small as 22 nanometers. And they say then can go done to 10 nm and below.

Wikipedia has some articles about how semiconductor chips are made.

How hey make Silicon Wafers and Computer Chips.

That is amazing!
