This was a project I started while getting my master's degree at Umeå University back in 2012. I learned a lot, and I was really proud of what I had created. However, everything must come to an end, and this is the end of Synergy. The application has not been updated since release, and I'm quite certain that a lot of the data by now is past its prime.
I had hoped to retire Synergy a bit more gracefully than this. The reason for the abrupt end was a server update that unfortunately caused a lot of issues, and I don't have time to get things up and running again. I sincerely hope that this is not too inconvenient for anyone, but at the same time I think that whoever would benefit from Synergy now have much better and more up-to-date sources of data.
The source code for Synergy is available on Zenodo, as well as dump of the database. Feel free to pick it up in order to get inspiration, or even reuse any code that you would find useful.
