I've been using Dolphon as my file manager, but it's very heavyweight and a little clumsy to use, I feel. So I had a look around and found xfe, which is advertised as being very like Windows Explorer, which is one of the best products from Microsoft (their optical mouse is the best). And that's what I'm using now.
Dismuke is something I found some years ago; it's a site devoted to music of the 1940s and before. I haven't visited it for a long time, and I went back there today. It's alive and kicking, and I'm currently listening to Radio Dismuke, available via TuneIn Radio on my iPhone. Lovely.
