2018-08-21 "Everyone does cool to IT system". For example, [長年日記]

"Everyone does cool to IT system". For example,

(1)"My wife suspected an affair of me" by error detection from GPS system of the smartphone.

(2)"I was shaken out of bed in the mid night" by an accident warning audible signal from emergency earthquake alert system

(3)"I was ignored by the other" by delivery delay of e-mail and SNS.

By the above case, not a few people come to be inflamed with rage.

However, I think that this accidents are inevitable because malfunctions occur and performance come down in any system. If anything, I think "they are natural".

-----

(1)Location detection functions of GPS go out of order, if the system lost the GPS satellite. The errors extend to more than ten kilometer.

(2)The emergency earthquake alert system is useless against inland earthquakes, and the alert should sound, even when the existence of earthquake is not fixed.

Above all, most message communication system don't guarantee the arrival, and never in realtime.
