As per the previous slashdot post about the huge amount of paper needed on aircraft and how replacing it with an ipad caused problems.
Very little of that huge stack of paper and how to handle the paper is related to pre/post flight check lists. The majority is exceptions If there is a problem then the pilots are expected to dig through that to find a remediation (if they do not already know)

In safety critical systems software tends to be designed to shut down if anything unexpected is encountered. It follows from the concept of "do no harm".

In some situations that is obviously not the best of ideas. There is nothing to say that the plane can not continue flying. Even if it requires shuting down the flight computers and deploying the RAT.

Comcasts customers are already paying to access Netflix. They are paying netflix and paying comcast. How comcast can not cope I do not know. As someone earlier pointed out End points will never provide symmetrical data transfers. It is always downloads. But then they are not stupid so they know that. I know they have a big network but how did they not give netfix a chance. Almost like they deliberately chose to mess around.

Station keeping is slightly different.
The wind and waves may shift the ship but the currents in the water are fairly consistent. The bulk of the ship is in the water and predominately affected by the currents. It takes a while for wind to affect it. and there is little to be done about waves apart from ride over them if small or correct for position afterwards if they are large enough to move the vessel.

Dynamically binding, you realize the magic. Statically binding, you see only the hierarchy.
