If folks are interested in having a person to talk to while doing SICP, we're doing it in the iPad app we released last Thursday. We were going to do a Show HN, but hey, HN's already talking SICP!<p>Understudy: <a href="https://itunes.apple.com/us/app/understudy/id782635884" rel="nofollow">https://itunes.apple.com/us/app/understudy/id782635884</a><p>The setup is basically like private music lessons. We pair you with a somewhat more advanced student also doing SICP. The deal is to<p>(1) Work on SICP by yourself during the week<p>(2) Once a week, discuss the material with your more advanced partner. The app builds in a videochat + whiteboard communication tool (you can see it in the app screenshots).<p>(3) When you get about a month in, also start discussing with someone who is just starting out. When you help that person understand, it very much improves your own understanding.<p>Basically, it gives you good discussion with people who are genuinely interested in SICP.<p>We've been running it in beta for a while – see <a href="https://twitter.com/understudyapp" rel="nofollow">https://twitter.com/understudyapp</a> .
