Ben Simon has a post up on his blog describing how he set up a scheme development environment on his Galaxy S9 Android phone. It was also an especially timely post as I had been eyeing a Mac Quadra with a Symbolics Lisp Machine extension card on eBay. As if we needed another reminder just how powerful current phones have become!
And no, I didn't put a bid on that Quadra - not quite feeling this flush at the moment.
Ben also mentioned that he installed vim, git and Emacs as part of the development environment. That alone is worth a blog post, and I think he has one on that topic, too. The screenshots show Emacs in a Scheme mode, how cool is that?
I'm very tempted to trying something like this on my Essential PH-1. I just need to get some sort of Bluetooth keyboard for it first.
