Since the new blog merges what was Coyote Tracks and my rarely-updated writing blog, Coyote Prints, you may get more than what you want here. If you only want tech posts, you can subscribe to the tech category feed. If you only want writing posts, you can subscribe to the writing category feed. (You can get a feed for any of the categories by going to the category page itself, if you really insist.)
And, if you’re following this as a link from Goodreads (hi?), note that the Goodreads blog is only pulling from the writing category.
Last but not least, if you’re subscribed to the Tumblr feed directly somehow (tracks.ranea.org/rss), you’re going to get what’s cross-posted to Tumblr, which is going to be mostly tech but probably kind of random.
