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.

How to hide a file in a plain image?

How to hide a file in a plain image?

One "hacking" type tutorial where I will show you how to hide a file (song, document, text...) in a regular picture!

For this you will need:

  • An image in which you will hide some files,
  • That same file,
  • CMD ( an integral part of every Windows OS ).

Hide file:

So, create a folder where you will insert a picture and a document (or simply put them on the desktop).

Open CMD:

  • For Win7/Vista users – open Start and type CMD and enter in the search.
  • For XP users – open start, click Run and type CMD.

Now type "cd desktop" (without quotes) if you have placed the files on the desktop. If you placed them in a folder on your desktop, type "cd desktop/folder_name" (where you will replace folder_name with the name of the folder where your files are).

Now type the following command "copy /b image.jpg + song.mp3 newname.jpg" (without quotes).

image.jpg – the name of the image in which you want to hide the file (if the image has the name balloons.jpg, then enter it as such),

song.mp3 – the file we want to hide (if the file is named secret.mp3, then enter it as such).

Ok, now click Enter and in the folder where you have those two files, a new file (more precisely, an image) named newname.jpg will appear because we entered that name in the command.

File detection:

Now you can send that new picture to a friend, or transfer it to a flash drive, etc. and everyone will see only the image and will not even know that there is a hidden file in it (in our case it is a song).

How to discover that file? First, we need to configure something in Windows.

Open MyComputer and click the left ALT (on XP, that Menu is already at the top). Now click on "Tools" and "Folder options".

Click on the "View" tab and leave the box named "Hide file extensions for known file types" empty.

Now go back to the new file you received and you will see that it says "newname.jpg", change that .jpg to .mp3 and THAT'S IT! The song is here!

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.
