For the past two days I have been working on a hard problem. The kind that eventually end up on my desk when everybody else have had their try. I'm the last hope, the one thing to try if all else fails.
I don't always have the answers. Actually I rarely do. At least in these kind of cases. If I would have known the solution I would have been able to teach it to somebody else. And if there would have been somebody to ask how to do it somebody would have already done so.
