Here's what a VPN can't protect you from (but you need to use it)

The abbreviation " VPN " has slowly become established among average Internet users, which is certainly good, but the problem is that people have started to see VPN as the ultimate solution to all problems.

Make your own Multitouch Pad

Make your own Multitouch Pad

Build your own Multitouch Pad at home in five minutes? It is possible to! See how.

For this you will need the following materials:

  • Cardboard box,
  • Plexiglas (or some ordinary transparent plastic),
  • White paper,
  • Web camera (any),
  • Computer.

Assembly:

  • Raise the sides of the box and glue them to make the box higher.
  • Cut the paper and transparent plastic to the dimensions of the top surface of the box.
  • Glue the paper to the transparent plastic.
  • In the middle of the bottom of the box, attach the camera so that it "looks" up.
  • Somewhere near the bottom of the box, on a page, drill a hole where you will pass the USB from the camera.
  • Place transparent plastic with paper on top of the box, and fasten it all so that it does not fall.

Software part:

  • Connect the USB from the camera to the computer.
  • Download these three programs and install: Finger Tracking, Mouse Driver, Multi-Touch
  • Start Finger Tracking and you will see what the camera sees. Touch your fingers and you will see white dots. So it works.
  • Mosue Driver allows you to control the cursor using another device.
  • Multi-Touch will allow you to use 2 or more fingers.

How it works?

The camera records white paper and since it is dark inside the box, the camera will recognize your fingers when you put them on the paper because a shadow is created. The Finger Tracker program recognizes these shadows and inverts them to white. It then tracks the white color that the camera sees. And the Mouse Driver program moves the cursor when the Finger Tracking program detects the movement of those white dots (your fingers).

New Google mobile internet saving application - Datally

I wrote an article on how to save internet traffic on an Android device and I suggested the Onavo Extend and Opera Max apps because they were the most popular back then. Meanwhile, Opera Max has been discontinued and Onavo has been completely redesigned and is now a VPN application with the option to save internet traffic. Their compression technology is probably now used by Facebook in its application because they bought Onavo - link . Google has decided to seize the opportunity and "push" with a new application called " Datally ".

How to change IMEI number on Android phone?

IMEI is an abbreviation of "international mobile equipment identity" and each mobile phone should have a unique IMEI number. You cannot change this number with the operator, but you can temporarily change it on your device. It allows the operator to accurately identify your device and thus enable/disable network services. Also, you can use the possibility of changing the IMEI number, at least for a short time, if you know exactly what you want, but I leave those ideas to you because this is an educational article.
