@spirovskib You were on the left side of the tree, still inside the tunnel, enjoying the shadow on a hot summer afternoon. (estimated 3 pm, about this time of year)
@spirovskib Third was cruising above the Löwengasse and recognizing "der gockel" as a name of a restaurant. Remembering the rooster. Logo seemed to match. Using street view at the Radetzkyplatz was kind of a challenge of its own.
@OSINTDojo How to find? Ask Google, it's almost too easy to be true: Wikipedia tells some things about Naenara, I had in mind that Red Star OS was derived from Fedora (confirmed by Wikipedia again). On my way I stumbled upon the user-agents database, that lists exactly one entry from 2013.
@OSINTDojo Naenara was intended to be an intranet browser for North Korea, so this user-agent appearance should be one of very rare occasions. Probably for this reason only one single entry of 2013 is found in the developers database of whatismybrowser. com
