Hi Mark, can you send me an example implementation on this? I'll try to find a solution that might work for both of us. It is easier to find the reason with a second reference implementation, I guess. Sebastian Am 28.01.2015 um 07:27 schrieb Mark Rizun: > I have the same problem with PolygonMorph.

It was a bit easy to say that. You can get frustrated by the state of certain libraries and I can tell you that we are fighting daily to improve the system (writing doc, fighting to get funds for engineers, coding).

> I see and appreciate your effort really, but there is no reason to > hide NumericalMethods from the book announcement. I do not know NumericalMethods. I vaguely recall that you were no happy that serge wants to change the code because it would not be in sync with the book. Now we can co-evolve them. Every I do is open-source and freely accessible so position yourself and join effort (I do not like SciSmalltalk as a name). Now we have the possibility to make on nice library but you need to sync. > I am trying to avoid what the Python community did with NumPy and > SciPy which is a mess. > Ah you see you have to sync with Serge. I think that Serge was not aware about that you publish the code in your repository. Now we want to rename the acronym (because DHB is not good) and probably improve the code of the library while keeping the book in sync (like using String streamContents for printing). I personally hate to see all the comment with a copyright and a commit dates.
