Wouldn't it be nice, I thought, if there was a version of GSAK that works with Linux. Then I thought about Wine, which gives you something not completely unlike Windows, working in Linux, and I tried it.
It's a bit umpty. It sort of works, but things crash at unanticipated moments, and geocaching.com access doesn't seem to work at all. But it works, kind of. And maybe I can get gc access to work.
So I can use my Windows machine for doing the geocaching.com access - that tends to take a long time. Then I can backup the database, restore it on the Linux box, and then make the necessary export of a GPX file from there. The file export is *much* faster from my Linux machine, which is at least partly because it's a much faster machine with a lot more memory.
I've also started dabbling in GSAK macros.
