I think that this apply specially for the first half of the summer, because the project begining was specially hard due I didn't have a lot of the needed knowledge, at this point maybe a task check list would be fine with deadlines. Now I have deeper knowledge than before but I feel that I spend to much time to get it. Any way as I said before this was a good sperience because I have gained experience in a bigger project than my university assignments. > > For example, there's an easy optimization task for JtR jumbo code that > > > runs on all platforms (so not Parallella specific).
