Cum convertesti diferite formate ( JPEG, PNG, TIFF ) pe Mac

Aplicatia ,,Preview’’ din Mac OS este mult mai mult decat un instrument de vizualizare a imaginilor. De exemplu, poate converti si exporta aproape orice imagine intr-un format diferit. Acestea sunt: PNG, JPEG, TIFF, HEIC si PDF. Aplicatia accepta noul format HEIC de la Apple. Daca descarcati imagini de pe IPhone sau IPad pe Mac si constatati ca ele au format HEIC, le puteti incarca in program si converti in JPEG pentru a le putea partaja usor cu prietenii.

Reset Your Ubuntu Password Easily from the Live CD

Our last article on how to reset your Ubuntu password easily through the grub menu was quite popular, so I’ve decided to make a series on all the different ways to reset your password on either Linux or Windows… today’s lesson is how to use the Live CD to reset the password.

Note that we’ll also cover how to protect yourself against somebody else resetting your password, so stay tuned!

Of course, this method will also work if you’ve installed your Ubuntu Live CD to a thumb drive.

Resetting the Password

You’ll want to boot from your Ubuntu Live CD, choosing “Try Ubuntu without any change to your computer” from the boot menu.

Once the system boots, open up a new Terminal window from Applications \ Accessories and then type in the following command:

sudo fdisk -l

This command is used to tell what device name the hard drive is using, which in most cases should be /dev/sda1, but could be different on your system.

Now you’ll need to create a directory to mount the hard drive on. Since we’re actually booting off the live cd, the directory doesn’t really get created anywhere.

sudo mkdir /media/sda1

The next command will mount the hard drive in the /media/sda1 folder.

sudo mount /dev/sda1 /media/sda1

Now it’s time for the command that actually does the magic: chroot. This command is used to open up a shell with a different root directory than the current shell is using, and we’ll pass in the folder where we mounted the hard drive.

sudo chroot /media/sda1

Now you should be able to use the passwd command to change your user account’s password, and it will be applied to the hard drive since we are using chroot.

passwd geek

Note that you’ll have to type your username after the passwd command in order to change the right password.

Now you should be able to reboot your system and log yourself in with your new password.
