The code to make screencasts free has been in for a while, but I rarely used it with the computation series because most of them didn't make sense in isolation.

The code to make screencasts free has been in for a while, but I rarely used it with the computation series because most of them didn't make sense in isolation. These new ones do make sense alone, so I'll probably do this more. I don't work with distributors at all because they tend to (a) want some level of control over content and/or the legal right to modify and reuse it, (b) offer unfavorable royalty rates, and (c) have mixed quality levels between the works they host. I like that DAS is a comparatively small body of work that people know by name and trust to be good.
