Boot Camp
For the last couple of weeks we have been talking about how to hand over hosting and maintenance of Activities.sugarlabs.org. In order to transfer the necessary knowledge to the Students at Rochester Institute of Technology, I am putting together a 'Deploying and Maintaining a Scalable and Reliable Web Service' bootcamp.
The format is series of 5 talks and hands on session in which students learn about systems in general while using activites.sugarlabs.org as a case study.
The High level question is, "What do I wish I knew when I started working on ALSO."
