GSoC 2012: we're in!

by Carla Griggio

Hi everybody!! I'm glad to announce that ESUG has been accepted as an organization this year :) So Google will be funding some Smalltalk projects of our choice. Soon you'll be able to find the next steps into the program at http://gsoc2012.esug.org/. Cheers! Carla Griggio & Janko MivÅ¡ek GSoC Admins

Ok, I updated the configuration, now it should work. Also, I temporarily uploaded the Arduino.dirTree.unix.3.zip<http://dl.dropbox.com/u/43706148/Arduino.dirTree.unix.3.zip> to dropbox because I can't seem te be able to access the ftp server I usually use. Feel free to try it out and tell me if it works for you. I'm sorry I haven't tested it properly but here at work I don't have access to a linux computer.
