OK, I admit it - I'm a dinosaur. I still use the command line a lot as I'm subscribing to the belief that I can often type faster than I can move my hand off the keyboard to the mouse, click, and move my hand back. Plus, I grew up in an era when the command line was what you got when you turned on the computer, and Windows 2.0 or GEM was a big improvement.
First, a confession - I actually occasionally call myself a coder, but in a tongue in cheek, post-modern and ironic way. Heck, it does make for a good blog title and license plate.
Like pretty much every other programmer with a Mac, I'm currently looking at Swift. Will I write anything but toy programs in it? I don't know yet - I don't really write any Mac-ish software on my Mac, just unix-ish programs. If Swift doesn't escape the OS X and iOS ecosystems it'll be a nice exercise in a neat language that's not really that relevant to the world at large, or at least to my part of the world at large. Not that this sort of vendor lock-in can't work well - Visual Basic 6, anybody?
When it comes to Emacs, I am an amateur at best, but part of the fun is that I keep discovering new useful functionality.
