Both. It is a live programming (not coding) environment in the spirit of Bret Victor, but it is made possible by automatic time management. You can't really show that however, so the essay focuses on the programming environment making the benefits more tangible while the paper focuses on the programming model (I point people at the essay first because many don't want to read papers). The paper is linked at the top of the essay.
