Osmium is now no longer.
In previous guides and posts I put often links to osmium.org for ship fittings and as an item database. Sadly those links now only lead to a blank page with some text where the raw data can be downloaded.
I’m pretty sure this was caused by the recent changes to EVE’s API and other services that where discontinued.
For me that means I have to think about how I will update all my guides. I’ll do that at some point but not in the near future.
