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

By Administrator
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?

By Administrator
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!

SIM card sizes (Mini, Micro, Nano) - explanation

By Administrator
Many users still complain about the size of SIM (subscriber identification module) cards. Which one goes on the phone? Can it be shortened? Can a smaller one into a larger slot? Although we are slowly switching to eSIM (more on this in this article ), we still use classic SIM cards. Newer phones usually require a Nano sizes, but operators issue SIM cards in all sizes. More precisely, now SIM cards are made so that the user can choose the size immediately, and later change it if necessary. More on that at the end of the article.

The difference between Sleep, Hibernate and Hybrid sleep options

By Administrator
What is the difference between regular Sleep mode and Hybrid sleep mode? And what is Hibernate ? I will try to explain in the simplest way possible so that everyone understands nicely. 1. Sleep When you select Sleep mode , all components of the computer except RAM are shut down to store data. So, if you do something on the computer and press Sleep, the computer shuts down and everything you did (left open windows, documents, etc.) is stored in RAM.
