One of the most frustrating aspects of Microsoft Windows is the automatic reboot after an important update. It is especially infuriating when you left the PC with a big download or a lengthy task ongoing and you return to find the login screen and your download/task interrupted.
Eventually, on the latest Windows versions, Microsoft implemented a prompt window that ask you if you want to delay the reboot:
But often it is not enough since it doesn’t offer the option to postpone the reboot indefinitely, but only for a specified time between 10 minutes and 4 hours, and more importantly it stays up only for a limited time and then, if it doesn’t get any input (that it may happen if you already left the PC), it takes the initiative to reboot the PC.

How to completely erase a file on Linux
As we have seen, simply deleting a file with a file manager or with ‘rm’ is not enough to really remove it from your hard disk and it is still possible to recover a deleted file.
Good news if you delete a file accidentally, but what can you do if you are in the opposite situation and you actually need to make sure that the file you are deleting doesn’t have chance to be recovered?
Fortunately in Linux there are some tools dedicated to totally erasing the file data: Shred and Wipe
How to fix the Heartbleed bug on your Linux Server
In the last few days a serious bug, nicknamed Heartbleed, has been found in the cryptographic software library OpenSSL.
This bug allows any ill-intentioned hacker to read the memory of the systems with the vulnerable versions of the OpenSSL software installed; with this kind of access an attacker can read the secret keys used to encrypt the traffic to the server including the usernames and passwords of the users and the actual content.
Fortunately only the 1.0.1 series (up to 1.0.1f) and 1.0.2-beta series (up to 1.0.2-beta1) of OpenSSL are affected by the Heartbleed bug.
