Anyone who has investigated SSDs for server applications is aware that flash-based SSDs have a limited life span.

It would therefore be a good idea to monitor for wear indicators in much the same way that we monitor spinning disks for signs of impending failure (reallocated sectors, etc.)[Read More…]

Nevertheless, I think that if you’re going to write something that will be viewed or used by the public, then you should make sure it’s correct. This applies especially to program code. Read on for some fun.[Read More…]
