Re: [Pharo-users] Pharo consultants

by StÃ©phane Ducasse

Thanks for your feedback. I agree with most of them (to me seasie is lacking a nice library of premade components), now you have also reef (lacks a good oducmentation that encapsulates javascript) and amber for the client side. With Pharo our goal is to make sure that people can make business. We are trying hard and I'm kind of obsessed by that :). So I love to hear that people created new projects, businesses with Pharo. I got some no public information from time to time that indicate that this is happening more and more :). Now we want more success stories. ;D So let us know how we can help you to arrive to the point where you want to get into pharo business.

Most probably you know that already, but you can load the changes of another image. That might help to ease the migration a bit :/: simply drag and drop a .changes file onto an image and you can replay whatever was in there...
