Re: [Pharo-project] [ANN] ESUG supports once again SqueakDBX

by Alan Knight

As far as the item of updating the Glorp port, that would be great. I note that there is a crude porting tool that generates Squeak fileouts included in Glorp. There is also the work that was done for Seaside that can convert back and forth between a Store database and a Monticello repository. I think that it is not trivial to set up, but since I am the manager of the authors it should be possible to get some help. That would also be nice to then have fixes flowing in both directions.

[Pharo-project] Bigger cursor

by Torsten Bergmann

Works for me on Windows with Pharo 1.2/1.3 and Standard as well as Cog VM. Haven tried on Linux or other platforms. Since it's code from OLPC I guess it should work also on non-windows platforms - but maybe the VM code was not integrated. You may ask on vm-dev list.
