When I get up at 5h45 it is softly raining but by the time I hit the road to work it has stopped and the roads are steaming, returning the rain whence it came. Leaving a kind of thin mist that slowly rises, greying out the sky. Whatever goes up must come down and in the afternoon the water is back. As rain.

The correction program works but testing is not at all easy because we cannot recreate the actual, error condition that must be solved. And because there is no margin of error allowed. This is a program that can only run once. The only way back is a database restore. The problem is that to verify the correctness of the program it must run before the backup and the result can only be checked after the backup. Thus restoring would cause the loss of a full day worth of orders (and unhappy clients) or the running would require a double backup which doesn't fit in a single night. Running over a weekend would be the best option but the opco's are not willing to call in staff for a weekend to solve a problem we created.

One dart and bulls-eye is required.

 

Did a third round of spraying the potatoes. The spraying did stop the blight so maybe it is the last round.

Adios
