We didn't stress test it so I don't know how it would react with big files and conflicts. It's a first version to say that we are compatible with it. If people shows interest in it, we'll improve it to handle edge cases if needed.
Whatever, I imagine you could find most of the answers to your question on the Remote Storage forum and website:
Thank you guys for the feedback! About the ease of use we are working on it via partnerships with hosting companies and ISPs. If you can't wait, you can check cozycloud.cc too.
Thank you 616c for your message!
About the minimum hardware required, Cozy made some progress on the memory footprint (lighter framework and usage of javascript runtime instead of coffescript one). Now you can use it with only 512MB of RAM instead of 1024MB. You can make it run on a RaspberryPi (B model) too.
You are right. I worked as BI consultant before. In our company the three main challenges we had were :
* collecting data
* having clean data
* extracting the right indicators and analytics from the data
I think the problems remain the sames with QS. Actual QS solutions lack of interoperability, do not really allow experimentations and do wrong about privacy. That's why Cozy could help: it allows to build data collectors in a few hours, a data browser is available to clean wrong data, and the best of all it allows anyone to hack new stuff on top of this new set of data without compromising privacy.
You are definitely right. About the motivation, I think that when people can actively participate to the decisions and are responsible of a subject, they are more motivated. Because agile and specially Light Agile empower every member of the team, they act as good motivators.
They are the easiest trackers to build. But I would like to add stuff like weather tracking (based on forecast API), number of posted tweets, number of github commits...
Cozy is free and open source, so you can host it at home on your NAS, your RasPi or an online server you rent. Cozy Cloud offers facilitators to host your cloud, if Cozy make bad things of your data, most of the users will leave and Cozy Cloud will probably close.
You can host it on your own machine. Even if you host it via an hosting provider, you can export all your data and your apps to any new servers like an home server for example!
