The web seems to be flooded by password removers. I'm however on the other side. I'm interested in security of my files.
If I have a WinRAR archive (> 1 Mbyte) and use a password (> 6 characters length with non-alphanumeric characters), how secure my archive will be?
Since I heard two versions and also read two versions in manuals to various devices, I would now like to hear the community opinion.
How should we connect a power supply to an electronic device?
Option 1: Connect the PS to the device, then plug the PS into the mains
Option 2: Plug the PS into the mains, then connect it to the device
I have two mobile phones from different manufacturers, and their manuals say the opposite thing. Why? Hasn't it always been a golden rule of the radio electronics not to let a PS run without a load?
