Linux/CentOS/Redhat – How to check for HDD Usage Time


Basicly you can check how long has your harddisk been powered on with the command below

The sample below shows the harddisk has been powered on for 9577 hours which you can calculate to 399 days. Which also means that the harddisk is more then a year old.

# smartctl -a /dev/sda | grep Power_On
  9 Power_On_Hours          0x0032   090   090   000    Old_age   Always       -       9577

How to Sync iCloud Contacts to Android

Sync iCloud Contacts to Android

I managed to get iCloud Contact Sync working on Android devices, this should work for every single CardDav compatible device.

On Android, install a CardDav app, this one is great and free.
  1. Add an account in CardDav
  2. For Server name enter
  3. Make sure SSL is checked
  4. For username enter your iCloud username (example and password enter your iCloud password.
  5. Press Ok, wait a few seconds for it to confirm
And voilla, your iCloud contacts now sync with your Android device, it may take a few minutes for them to show up.

I hope this helps

Update: You may also wish to enable two-way sync with iCloud, I’ve enabled this and have had no issues.
