Due to my enormously busy life, I no longer update this blog. However, I’ll be leaving it up indefinitely so you can grab a tutorial every now and then. I’m also closing comments at this time because I won’t be stopping by that often. My thanks to all of you who still visit! I’ll be starting another blog shortly, but it will be a bit more general, to accommodate more of the things I’m interested in. I’ll post here as soon as that site is available.
