iPhone 5S: Problems with all motion sensors!

Some units of the DayOne iPhone 5S showed serious problems with regard to the motion sensors!

Apple has always been known for the quality of the Assembly and the reliability of the hardware used, however the new devices are highlighting serious problems for youth, particularly with regard to the reliability of the iPhone's motion sensors, adopting for the first time the M7 co-processor dedicated to managing those sensors.

Some of them had already talked about some issues regarding the compass and level, but Gizmodo has made ​​a careful analysis in which the results are compared to those smartphone tools for measuring physical activity. The outcome of the tests is negative on two drives that show inaccurate values ​​even up to 6 ° with respect to the reference ones. The problems are due to calibration errors of accelerometer, compass and gyroscope.

Inside of the tests is also used an iPhone 5, that with the same operating system does record values ​​in line with respect to those of the instrumentation. This element would suggest the possibility that the problems in the new iPhone 5S is not to promote software. With regard to the accelerometer, also, this seems to have a delay in the response higher than that recorded by the previous model.

Gizmodo points out that its test methodology is far from definitive, however it seems in line with the results from other American newspapers had. It is not clear to what extent the inaccurate readings from the motion sensors are hardware related, although some users have provided for the warranty replacement iPhone 5S, reporting that the problem has disappeared altogether.

How to block websites on Android

Do you find yourself often to lend your smartphone to friends, brothers, cousins, etc. and you'd like to be able to block certain websites on your phone, in order to limit Web browsing and you don't know how to do it?  If your smartphone is equipped with the Android operating system, you can do it.

If you want to know in detail how, take five minutes of free time and read the directions that I am going to give you. We will see quickly how to block websites on Android using two separate applications, one for unlocked phones (that was done the root) and a somewhat more limited but also works on locked phones. Let's start now!

If you want to know how to block websites on Android and you have an unlocked phone, I suggest you install Hosts Editor. This is a free application, as suggested by the name, it lets you modify the hosts file on your smartphone. If you don't know what I'm talking about, the hosts file is a file on your computer that lets you force the redirection of Internet sites to IP addresses. Taking advantage of its features, you can then make sure that the phone redirects the sites you want to block an IP address different from the real one (in this case, localhost, or the same device) making it unavailable.

To block a site with Hosts Editor, what you have to do is launch the app, press the Menu button on your phone and select New entry from the menu that appears at the bottom. In the screen that opens, type 127.0.0.1 in the field IP address, the address of the site you want to block in the Host entries (e.g. facebook.com) and presses the Save new host that is located in the upper left corner to save your changes. For the changes to take effect, the phone will restart automatically.

After restarting your Android device, try visiting the site you've stuck with the Host Editor and this should be unreachable by any browser. To unblock the sites previously obscured in the application, put the check mark next to their name, press the Menu key and tap Delete this entry first in the menu at the bottom of the screen, and then click Yes. Even in this case, to save the changes, your phone will restart automatically.

If you do not wish to run as root on your smartphone, you block websites on Android using Safe Browser. It is a browser, to use in place of the default, allowing you to create a blacklist of  Web addresses to be blocked. Unfortunately it does not obscure the sites also in other browsers installed on your phone, but without root it is difficult to get more.

To block a site with Safe Browser, you must first create an administrative password for the application. Press the Menu button of your smartphone, select voice Admin from the menu that appears and set your password in the screen that opens. If the first time you launch the app,it asks you to enter a user name and password combination, ignore the request by pressing the Back button on your phone.

Once you set the admin password, you can block any site you want to,by  simply  visiting it and pressing the Menu key on your smartphone. Next, select Other from the menu that appears at the bottom and tap on  Add blacklist button to complete the operation.

When you change your mind, you can unblock sites blocked out in Safe Browser by pressing the Menu button on your phone and going in the Settings menu of your application. In the screen that opens, you should then press on the item Blacklist and select the address to be viewable again. That's it!

Wifi makes room for Li-Fi

In this Start-Up from Paris's all about two years only one: LI-FI.

"Light Fidelity", that is data transmission via beam, says Cedric Mayer:

"Here we see a LI-FI receiver. He reads the data of the beam and then turns them into music. If I cover the receiver... or under a different light source in place..."

It is now possible to not only music, but also video transmission through beam.

The images of this surveillance camera sends a LED beam at the screen.

How does it work?

Cedric Mayer:

"The LED light is on at high speed and switched off. Lights out is for 0, light on for 1. So zeros and ones in fast rhythm will be shipped. A transmission speed of up to 3 GB per second could be achieved, at least in theory."

Thus, LI-FI is 150 times faster than Wi-Fi (Even though some people try to crack wifi password for getting free access to Interet).

Soon, it might be possible to send information by means of a light-sensitive sensor to a computer.

A classic modem, which is connected to a LED light bulb, would suffice.

The new technology also emit no electromagnetic waves. You could go online then so also on the plane or in the hospital without any risk.

Despite its many advantages, the light fidelity has also limitations, said Jean-Yves Le Boudec:

"The device, for example your Smartphone must be exactly positioned. Otherwise it can beam of the light bulb of course a fundamental problem for the mobile use of the technology."

Several German, Japanese and American companies try to make use of the system for the Web. Paris is already talked about a product, which will be from 2014 for under 80 euros on the market.
