Move it to moose this is an old abstraction about what is a circle or a line.

[Pharo-project] [ Off Topic ] Smalltalk Everywhere

by Sven Van Caekenberghe

Today I was in Bremen visiting our German partner, and in the corridor of the restaurant we went to, overlooking the airport, I couldn't help noticing this nice piece of art: One has to wonder if the artist even knows there is a programming environment called Smalltalk. I can't claim I 'understand' the piece. Sorry for the terrible quality, bad light, old iPhone. Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

And with OpenQwaq's Smalltalk-Python bridge you might even be able to pretend it's Smalltalk turtles all the way down, without having to attempt to re-implement Paxos? frank

You might look at http://openreplica.org/ if you haven't. Its a python distributed object store that uses Paxos to ensure enough identical copies are preserved across machines. Instead of passing objects the messages sent to objects are sent to enough machines so that there is a quorum that have identical state. If one machine does down a replacement has the objects loaded via serialization. But most of the time its just sending messages around. Or something like that. Also probably need a faster GC.

I thought that I got rid of all the explicit references to FileDirectory and ReferenceStream, so check to make sure you're using the latest version of OSProcess. Maybe I missed a few of the references, there were quite a few.

Move it to the Moose team, please. I extracted it from a previous code and as far as I know, it's only Moose that uses it.
