Some news from the growing pharo teacher front

by stepharo

Hi guys I want to let you know that there will be a new pharo lecture in YaoundÃ©. I presented Pharo during a seminar and the previous minister of education was there and asked us to do a lecture. In June we did it with Damien C. by skype. And now there is an official lecture at YaoundÃ© given by Prof. Metalagia. This is an excellent news. I will give some lectures in december there. In Togo my first visit was quite successful: 120 participants to the conferences I gave (it was still vacation time there). There were 60 students following lectures from 8h to 17h during 4 days... Yes I'm exhausted ;) A new Pharo lecture will start in north Togo. I will go back in December. One of the idea is to help students to get good in Pharo and pharo web stack and build web apps and other. I hope that we can have within 2/3 year There is a competition AppTogo. People are learning C# and others. I hope that some students will compete with Pharo so I will be looking for potential mentors to help them. Giving them advices, pointing them to the right solution/framework and may be a bit of pair rogramming if skype works. I distributed the Pharo Starter Kit (we will announce it officially now that I have 10 gb space on my server) People love the Youtube videos folder I'm collecting. Yes internet is a pain there. Chloupis I put your great youtube tutorial! Thanks for it. some students watched it. Stef

The gouverment in really pushing in that direction. There is a competition AppTogo. People are learning C# and other languages. So nothing is that easy :). I hope that some students will compete with Pharo so I will be looking for potential mentors to help them. Because I will be busy working on the mooc and other actions.

Re: [Pharo-users] Problem Loading Roassal 2 development in Pharo 4

alex did you add this version as stable for pharo40 in the configuration? Because this is a nice way to document that a version can load in a given version.

Hi, I have changed the grafoscopio install script by this: http://ws.stfx.eu/8ACI49YES8Y4 trying to refer to a stable version of Roassal. Still I get this error: ~~~~~~~~ This package depends on the following classes: GTExampleFinder You must resolve these dependencies before you will be able to load these definitions: RTExampleFinder gtExampleInstance class:selector:method:to: newExample ~~~~~~~~ Any way to refer to a stable version of Roassal that shows the examples gallery? Thanks, Offray Select Proceed to continue, or close this window to cancel the operation.
