Your server appearing pretty slow could be many things from wrong configs, scripts and dodgy hardware – but sometimes it could be because someone is flooding your server with traffic known as DoS ( Denial of Service ) or DDoS ( Distributed Denial of Service ).
Denial-of-service attack (DoS attack) or Distributed Denial-of-service attack (DDoS attack) is an attempt to make a machine or network resource unavailable to its intended users. This attack generally target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers. DoS attacks are implemented by either forcing the targeted computer to reset, or consuming its resources so that it can no longer provide its services or obstructs the communication media between the users and the victim so that they can no longer communicate adequately.

Have you had enough of nice and friendly heroes? Then become the villain of the piece! Get your own back on the pathetic forces of the good and make them finally understand that evil is something to be taken seriously, and must be well done.

Evil spirits, boastfulness and a tendency towards machievelic laughter will finally be rewarded through a title which renews the codes of the genre. You can find all of this and a great cartoon style graphics in this new title (it’s been released on 16 of April for Linux):
