I just launched a site to share ‘books’ of code playbacks. These are guided walkthroughs of some code as it evolves with a narrative from the author. The narrative can include text, whiteboard-style drawings, images, and videos.<p><a href="https://playbackpress.com/" rel="nofollow">https://playbackpress.com/</a><p>I have been using these in my programming-focused CS courses for a couple of years. I always give an anonymous survey at the end of the semester and the feedback has been very positive. Students prefer them to traditional programming books (no surprise) and to videos (I was a little surprised). Next, I want to make these available to others. I am hoping to shake up the traditional programming book publishing market.<p>I’m looking for feedback on the medium of playbacks and the likelihood of these replacing books/tutorials/videos. If you are an enthusiastic supporter, I am also looking for new authors and partners/cofounders.
