I really like the idea of using Pharo/ROASSAL for data viz especially in the context of southern countries (you talk about about Global South in your document). Having a portable environment is definitively a plus in the context of countries where the bandwidth is really limited. My lab is working with developing countries (including south-america) and we could exchange some private emails on how to sustain such a project. I'm interested by such tool in the context of health and/or crisis issues for example.

Data Kitchen: A data visualization project powered by Pharo. Feedback welcomed.

by Offray Vladimir Luna CÃ¡rdenas

Hi, In my effort to more create more meaningful computer mediated experiences for me and other and to use Pharo as a medium for that I have proposed the following project: --- - Name: Data Kitchen: Frictionless data, moldable tools, pocket infrastructures & permanent workshops for community empowerment - url: https://www.newschallenge.org/challenge/data/entries/data-kitchen-frictionl… --- It combines the ideas of moldable tools, agile visualization in this community with some of other like frictionless data, by Open Knowledge Foundation and what I call "pocket infrastructures". Any feedback is welcomed. You can make it here in this list, but if you can made it on their platform, from a simple "heart" (+1) or drop me a line, it would be greatly appreciated and it will help to make more visible the project. Thanks, Offray

Re: [Pharo-users] Roassal3D is moving...

by Offray Vladimir Luna CÃ¡rdenas

Wow! Pretty awesome :-). I remember some "hacker" movies where 3D interfaces where used to navigate the system... now we're closer :-). This works with Pharo 4? Some package to install? (or is available only on 5?) Cheers and keep the good work. Offray On 09/10/15 10:28, Alexandre Bergel wrote: > Hi All! > > We are (secretly :-) working on Roassal3D.

Hi Ben, Thanks for looking into this. I've gone through your steps on my machine (the image filename is Pharo-40622.image so I assume that is a build number) and I get the same error you do. As you say, the errors are not identical but hopefully this will lead to a fix for both. For continuing my work, I am going to install a fresh image, and hopefully I can still rename classes as long as there are no MessageBrowsers open. I'd be interested in hearing other workarounds.

Pharo 4 debugger

by bsselfridge＠gmail.com

In Pharo 3.0 there was a Add/Remove breakpoint (experimental) method popup menu option. I do not see this capability in version 4.0. Is this feature still available or has it been removed? If still available, then how does one get it instantiated?
