Self awareness. At first, you just sit and let thoughts go through your mind, acknowledging each one. "I am breathing. I feel a little more tired than usual today. My dog is barking again." You just acknowledge and move on. Let yo

10^14 is bits. When you divide 10^14 by 8 you get 12.5 trillion bytes, or 12.5 TB. If you have 4x 4TB drives in RAID5, and one fails, then in order to rebuild with a replacement drive, you have to read all data from all surviving drives (3

This can not be stressed strongly enough. There is never a case when RAID5 is the best choice, ever [1]. There are cases where RAID0 is mathematically proven more reliable than RAID5 [2]. RAID5 should never be used for anything where you va

Best bet is to leave work for lunch. Sit in your car if you have one, wearing sunglasses. Best if your car has tinted windows. If your building has a parking garage, that is ideal, less chance of random person thinking you are dead and call
