5th June and my fourth day of training was a busy day. I first tried to installed rt^3 as I want to work on BRL-CAD. I tried to install and compile it but unfortunately it was locked with some kind of password, that is there was some password problem. So now I am trying to find a way to install it. And side by side I worked with the soverneir team and helping them to solve their problems as our progress is quite slow. I planned everything with them what to do, specified targets that we need to acheive. I also helped the junior members to install LAMP server as they were tired of struggling with the localhost. So, I just helped them out and also took some other problems of the beginners. My all day till 5pm passed with this only.
