How to make google chrome only for internal use? Sounds like another braindead corporate policy. Pain without a gain. |

Why does a hardware router perform better than a Linux router with better specs (RAM & CPU)? It works both ways, too. The hardware doesn't need to deal with rare, complex cases either. It just throws those to software. Routing loops? Don't try to figure out in hardware how to deal with those. |

Is there any DNS system or Service that is HTTPS aware? This would also require all DNS clients to cooperate; standard DNS clients do not include the application. Hence, there is no way that the DNS server could respond differently, even if you could modify the DNS server. |

How it was detected if last ACK lost in TCP connection termination procedure? @sonali: It's a fundamental issue known as the "Two Generals problem". You cannot detect the loss of the last message, because that would require another "past-the last" message. |

Utility to LOGICALLY compare two xml files? XML InfoSet can actually specify order constraints, so the idea that XML is unordered is debatable. And you're certainly not allowed to merge the attributes of two elements just because the elements have the same tag. That would only be valid in specific XML applications, but a generic tool will not assume that. |

Convert a Smart Array RAID5 array to a RAID6 (ADG) variant @SmallClanger: RAID6 can survive any 2 disk failures; RAID1+0 has a 33% chance of data loss when two disks fail. |

Blade servers in small office server room (90db)? "Long periods of repeated exposure to workplace noise levels between 75 dB(A) and 80 dB(A) present a small risk of developing a hearing disability". 90dB is twice as loud, and therefore simply unacceptable. Manageable doesn't even enter into the picture. |

Available EMP protection devices? @TevoD: No, but if the UPS is close enough to the faraday cage (either inside or outside) then the conductors (antenna's) will be too short to effectively radiate. |

How to stop users from running CPU heavy programs on a server? A bit more effective would be a small script that selects the top 5 CPU-consuming processes ( ps -eo pcpu,pid,user | sort -k 1 -r | head -5) and renice those. You could do so from a cronjob. |

How to stop users from running CPU heavy programs on a server? Considering it's referencing ulimit, seems this is implemented as RLIMIT_CPU : "CPU time limit in seconds. When the process reaches the soft limit, it is sent a SIGXCPU signal. The default action for this signal is to terminate the process. However, the signal can be caught, and the handler can return control to the main program. If the process continues to consume CPU time, it will be sent SIGXCPU once per second until the hard limit is reached, at which time it is sent SIGKILL" |

Engineers are using explosives to remove hard rock outside our office building. What countermeasures should we take? Silicon Valley is one of the most earthquake-prone areas in the world. Stuff that works there will survive a few shakes. |
