I decided to look at the Rails Rumble projects today and have found several that look very promising. Some could be applied to the cloud and some just solve some interesting problems. Below are some of my top picks:
GitWrite – A Blogging Platform backed using Git, Rails, and Twitter!
Monitoring:
StillAlive– Focuses on website monitoring, but at a new deeper level not just simple pinging
Monitaur – Looks at server statistics and tracks details of processes, disk, swap and more
Miss Monitor – (this is their summary, the project isn’t up yet) > Collect, aggregate and visualize static and dynamic data about your application and libraries. This includes for instance performance data collected from services like New Relic or code statistics like flog score and lines of code.
