On Debian/Ubuntu, installing ia32-libs used to meet all the dependencies. But then the OS builders/packagers decided that ia32-libs was a hack and "improved" upon it...

Not sure what is the latest but in the VMs/images that I run, no-display meant that some display initialization is bypassed, so VNC into Pharo won't work, while vm-display-null allows VNC, which is how I am managing my image. I wrote some old blog posts on this, I think. Here's my daemontools run file that is running my Pharo-powered blog: #!/bin/sh /usr/bin/setuidgid app1 \ /pkg/pharovm/pharo -vm-display-none -vm-sound-none app1.image "app1" is the uid/gid pair that I run the service on. This is on Ubuntu Trusty. Used to be FreeBSD, and if I ever have the time to get Pharo VM and NativeBoost run on FreeBSD, I may go back. -- Pierce http://www.samadhiweb.com/blog

Re: [Pharo-users] History not available in Playground

Hi, Do you have a package-cache folder in the same location as the image and changes files? The very first time you download a new image in a new location you will have no ... menu. You can use the settings browser to change the path where the playground looks for the package-cache folder.

I didn't build Flow, nor use it on GemStone. But to clarify concepts Flow is a full web stack which *uses* Mapless for its persistence. Mapless is a NoSQL framework using MongoDB by default, but AFAIK there is a Mapless implementation using GemStone/S, which is no surprise given the fact that most NoSQL are key-value storage, way less than what a persistent Dictionary can provide. :) I'm looking forward to bring Mapless to PostgreSQL, considering PG 9.4 have native JSONB storage.
