To celebrate the finishing of our book on numerical methods (written in Finnish), I'll post the cover picture here.

The book was sent for printing today, and the second edition will appear in two weeks. Editing and writing the book has been a rewarding experience, although it has sometimes been a bit tiring. But I managed to browse through the book one more time, and found additional five missprints. That is not too much in a 415-page book. I made the corrections also to the PDF version of the book available online.
