Re: [Pharo-project] OSProcess - working on gnuplot

by Schwab,Wilhelm K

Stef, The only problems I have found are in the unit tests, which somewhere along the line cause a vm crash. Otherwise, it seems to work. Until it either proves unstable or otherwise lets me down, I'm trying to press forward with it, since I agree that it is REALLY important that this and other other FFI-like features work and work well. In general, I find the Linux vm to be too willing to crash w/o leaving a trace, or at least a trace that I know how to find(??).

Re: [Pharo-project] Socket accepts ipv6 addresses, but can not connect to them

by Schwab,Wilhelm K

Bart, Good question, and there is no easy answer. The Linux world seems to be having convulsions over it, and every time I re-learn how to shut it off (it does bad things to my DNS lookup times), I find comments about how poorly designed it is. I'm not saying the comments are correct, but I note them. For now, IPv6 is probably better left for opt-in than opt-out. There should probably also be very good separation between IPv4 and IPv6 name resolvers, allowing a clear separation of the associated primitives and methods that depend on them.

I am more interested into Figure 13 (http://www.svgopen.org/2009/papers/58-Interactive_Documentation_using_JavaS…) and 14. In Morphic (with the exception of the arrows) this is easy to do when nesting some containers into each other.
