Hi Sean, Stephan, I just updated the PharoLauncher and it should now work fine for 64-bits images. I just had time to test it roughly but you can give it a try (https://ci.inria.fr/pharo/view/Launcher/job/Launcher/149/) Christophe. > Le 20 sept. 2017 Ã 10:52, stephan <stephan(a)stack.nl> a Ã©crit : > > On 20-09-17 08:26, Ben Coman wrote: > >> Must be something environmental in lookup paths.

So actually I use > the one built on CI. ) I really like describing domain objects with Magritte and using chains of visitors to add cross-cutting concerns like translations, styling and access control. The resulting domain code is very clean and DRY. To map to database/Glorp I would just add properties to the description wherever needed, and add a visitor creating the mappings. We didn't need that as we developed in Pharo and deployed on Gemstone. At the moment QC generates applications using jQuery, and the live updating needs a round-trip to the server. You might want to substitute that with something that does more client side. I haven't looked in detail at what Johan Brichau is doing. An open issue is live updates that update each other. That needs automatically calculating dependencies and update order. I've copied the latest configuration and added #'pharo6.x' but that is not enough. Stephan

I'm trying it with Pharo 7 images for the first time.

Its a shame nog being able to read the article, because it is not posted in the open web and I don't have Facebook or Google to pay with my privacy for the "privilege" of reading Fast Company. Anyway, I agree with Hilaire. It's pretty difficult to be between worlds trying to bridge education and informatics (or activisms) when one part is extremely focused in their own extreme of the bridge and the stuff at the other side is so alien.
