Cisco Router Hack Inspires New Patching Religion

ancientribe writes "The dirty little secret about patching routers is that many enterprises don't bother — for fear of the fallout any changes to their Cisco router software could have on the rest of their infrastructure. But the recent discovery of a way to easily hack these devices has put pressure on organizations to change their ways and patch. This article in Dark Reading gives tips on how to patch without taking down the network, including input from Cisco's own director of IT on how Cisco itself handles router patching."

Why should they? It has little bearing on the basic things that are important in day-to-day life.

      Humanity will always have leaders. Leaders have always exploited those they lead. It is no different with science. It can just as easily be bent towards corrupt goals as religion can, or for that matter sports, wealth, comfort, etc. Most religious people could give a shit about how old the Earth is. It's when their leaders have stake in that claim for political reasons that it becomes an issue. Especially when the followers of reason tell them they are stupid for having faith. I am convinced that what needs to be made clear to religious people is that, like you say, science comes up with the best explanation given the facts at hand and by testing observations. We should be making it clear to religious people that to simply brush these observations away at a whim is intellectually dishonest. We need to make it clear to them that we believe in their freedom of religion - and we truly should believe that. We need to make it clear to them that censoring science is an insult to their faith. If there faith is so weak it cannot stand to reason, it is no faith at all (in the sense that if the Earth were 6000 years old, their higher power could make millions of years of geological processes happen in 6 days by speeding up time or something, higher powers are supposed to be all powerful right?).
