Late yesterday I put up a follow-up video to Friday's video on piping: the update is here. I give a pratical example of two of the biggest pitfalls for cli newbies: problems with spacing and understanding streams. We write a command that gives you a choice of all videos in a directory from which you can select and watch one.
I also just released a video "Everything I Want to Do Is Illegal" on the book by Joel Salatin by the same name. Superficially, it might not sound too relevant to too many of my subscribers' interests, but I think you'll find it pretty important.
