As software developers, we know our software will fail; someone will use it in a way we did not anticipate, we will forget to properly check input, a process will time out, and we will make typos.
For these reasons, and many more, people spend time and efforts on reproducing problems, and finding and fixing root causes. If this hasn’t caused too much of a delay, there may even be time to make sure these problems never show up again.
It is inevitable. Or is it?
