I've been a big fan of Julia Evans' writing since I discovered https://jvns.ca/ a few years back, but I didn't dig too much into other areas of her site. I was reading through my feed on Mastodon and saw mention of her zines and assumed they were comics or something like that that she did as a hobby.
I was wrong! Julia's zines are exactly the kind of thing I adore: accessible presentation of foundational technical concepts, beautifully crafted. The topics are excellently chosen...here's a quick sample:
These are paid, but I have no affiliation or interest beyond sharing a cool thing. If you want to get a feel, she also has some free zines, like So You Want to be a Wizard.
If you're interested, you can check out the whole collection at wizard zines!
