I don't think we're anywhere near the equivalent of any library or application being named starting with a J when it was written in Java - and not even actual words beginning with J - just slap a J at the start of any old name.
Totally agree. Back in 2004 I used it daily to bridge between two PCs running on one network, behind a firewall with one running the synergy server and the other the client, and a laptop running the client. Both PCs were under my desk with my laptop and two screens from the PCs on top. I had one keyboard and mouse across three screens powered by three computers and could seamlessly not only move my mouse across all 3, but also copy paste text across too. I believe a newer version (which may never have materialized before it went closed source) was going to have drag n drop across too. It was so easy to work with and remember it very fondly. It was magic stuff.
And it's also valid for UK postcodes to be reused, e.g. following demolition of the original buildings, e.g. tower blocks, the postcode may be deactivated for a period of time, then reactivated when new buildings elsewhere need a new postcode.
