@kaveh808 - since you mentioned spending a lot of time on the Common Lisp tutorial for your friend - it would be awesome if you'd repurpose it as a general tutorial for people new to or interested in Common Lisp, maybe as YouTube videos?!
I certainly second this. The entries on that blog are amazing, really. Thanks for them!
That's an interesting idea...
Been developing my software and updating the blog while I think about YouTube tutorials. Have to figure out how the screen recording works, whether I need to film myself, audio and editing, etc.
