I’m having a terrible time with the web today; it’s like half the internets are offline, including Google. But some sites are available, so I don’t think it’s a technical problem at my end. Are your links working where you are?
Update: Whatever the problem was has fixed itself. Carry on.
I seem to remember that Isaac Asimov formulated a set of rules for machines, perhaps in I, Robot. One of them was that a machine must be able to repair itself. I smile when the technology around me does exactly that.
