You can help me

by horrido

I'm writing an article about Pharo. I would like to list the Top 10 "really big" things that have been developed in the past several years, /or are being developed right now/. Please word it in a way that laypeople (like CTOs and non-Smalltalkers) can understand. Thanks. (I know "really big" is rather subjective. I leave it to your discretion.) -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Stef Done - https://pharo.fogbugz.com/f/cases/20363/ThemeIcons-downloadTo-has-an-argume… What really puzzled me is that this situation was not picked up by a code critic.

Re: [Pharo-users] How to create a minimal image ?

by Stephane Ducasse

We are talking about **Pharo Core** and we will reduce it even more. Then you can load the UI. And no UI is not the very essence of Smalltalk. You can connect remotely to a live kernel and program it and this is still a live system.

Esteban, I'm happy to report this package works for me, in my RH/CentOS 6 environment. I have to do a bit more since I have to install it in a network path (can't install in each server). If there's a download option instead of an rpm, such as that in Pharo 5 download website, that would be great. But I don't want to complain about it.
