Justine here. I'm glad to hear you've been enjoying it! A lot of what I do for fun in my spare time is read old code, since I want to understand the hopes and dreams of each generation, and then find some way to capture the essence of that dream using the advantages of modern tools. For example, https://justine.lol/sectorlisp2/ was a really nice blog post that recreates the idea of LISP as it existed around 1960, except much smaller and beautifully polished since we now have better tools than punch cards. I'm obviously much younger than the original LISP hackers, but I put a lot of effort into understanding and faithfully recreating their ideas. I even colorized the LISP 1.5 listing for my blog https://justine.lol/sectorlisp/ while I was reading it, since you really get to know people when you read their code. In any case, you can expect some more content from me in the upcoming weeks.
