My posts assume a fairly wide range of levels of background knowledge. For that reason, I’ve labeled posts by the estimated amount of background knowledge you’ll need to be able to make it through the post (+ means little to no background knowledge assumed, +++ means lots).

My posts also tend to vary in length a fair amount, so I’ve also included length information for each post.
