Another magic number to remember
Today's message is brought to you by the numbers 787 and 248.
This condition is caused by a software counter internal to the GCUs that will overflow after 248 days of continuous power.
What's 248? Well, a 32 bit signed number rolls around 2.1 billion, with 86400 seconds in a day (usually!) and a 100 Hz counter...
$ echo '(2^31) / (86400 * 100)' | bc -l 248.55134814814814814814
There you go. Another one of life's magic numbers.
